This document discusses how ecological scaling laws are linked and can covary due to eco-evolutionary dynamics. It presents a stochastic model of eco-evolutionary dynamics that can analytically characterize the stationary state and linking relationships among scaling exponents. The model shows that different values are possible for scaling exponents as long as they satisfy relationships ensuring consistency and constraints on total metabolism.

Impact of Environmental Noise in communities of neutral species - Jordi Hidalgo
Impact of Environmental Noise in communities of neutral species - Jordi HidalgoLake Como School of Advanced Studies
This document discusses the impact of environmental noise on neutral community dynamics and species coexistence. It first introduces neutral theory and its assumptions of equivalence among species. It then notes that most neutral models do not consider how abiotic conditions may change and affect species differently. The document examines how environmental variability is incorporated into population dynamics models through tools like the unified color noise approximation. Simulation results show that environmental noise can smear phase transitions and increase the number of coexisting species under certain conditions by creating a storage effect. The key messages are that environmental variability changes our understanding of phase transitions, can favor or disfavor species coexistence depending on how it modulates fitness, and that the interplay between timescales is important.Ess Topic 1 - Systems and Models
This document outlines concepts related to systems thinking from pages 69-90 of the IB ESS Course Companion. It defines key terms like systems, open and closed systems, feedback loops, and equilibria. It also explains how systems can be analyzed on different scales from cells to biomes to the whole Earth. The document provides examples and details about how systems thinking is applied in environmental science.

1.3. Energy and equilibria
The document discusses key concepts related to energy, equilibria, and feedback mechanisms in ecological systems. It defines the first and second laws of thermodynamics, explaining that energy is neither created nor destroyed, but can be converted to different forms. Systems can exist in stable or unstable equilibria between which there are tipping points driven by positive and negative feedback loops. Positive feedback amplifies changes while negative feedback contributes to stability. Tipping points occur when small changes cause large effects and a shift to a new equilibrium state.

1 s2.0-urbag ecoservices concept
This document introduces the EPPS (Ecosystem Properties, Potentials, and Services) conceptual framework. It discusses how ecosystem properties describe the biophysical structures and processes of ecosystems. Ecosystem potentials are then derived from the properties to represent the potential for ecosystems to provide services. Finally, ecosystem services are defined as the benefits ecosystems provide to humans. The framework aims to better integrate ecosystem services into spatial planning by linking potentials and services. The document then applies the EPPS framework to analyze urban ecosystems, their properties, potentials, and services.
Improved N Retention Through Plant-Microbe Interactions
- This poster examines the impact of crop diversification (4-year rotation) versus conventional (2-year) cropping systems on soil and rhizosphere microbial communities of maize.
- Diversified systems had richer, more even microbial communities that differed in structure from conventional systems. Diversification decreased AOA and AOB populations.
- Maize roots hosted distinct microbial communities that varied by cropping system. Diversification led to lower AOA and AOB abundances in the rhizosphere.
- Overall, diversification modified the microbial community in ways that could improve nitrogen retention through tighter coupling of carbon and nitrogen cycles.

Emergence of elevated levels of multiple infection in spatial host-virus dyna...Lake Como School of Advanced Studies
This document discusses how spatial dynamics can affect the distribution of multiple infections in hosts. It finds that high virus adsorption leads to clustering of viruses around hosts. This clustering causes the distribution of multiplicities of infection (MOI) to have "fat tails" that deviate from the geometric distribution expected from a well-mixed model. The dynamics are driven by invasions of clusters, which skew the MOI distributions to have more hosts with higher MOIs. Future work aims to model spatial dynamics of viruses that infect other viruses.A quantitative view on mRNA translation: the relative role of initiation and ...

The document summarizes research on quantifying and modeling mRNA translation, specifically the relative roles of initiation and elongation. It describes studying ribosome traffic to quantify protein production rates. Experiments show that the relative positioning of codons during elongation can affect translational efficiency. A quantitative model is developed that can predict translation efficiency based on initiation and elongation rates and how depletion of ribosomes affects gene expression. The model is consistent with experimental data on how initiation rate affects mRNA efficiency and ribosome density.Evolution of transcription factor families along the human lineage

How can cells precisely measure time-varying external signals? - Giulia MalagutiLake Como School of Advanced Studies
This document discusses how cells can precisely measure time-varying external signals. It summarizes that cell sensing systems are surprisingly accurate, but are limited by noise and cellular resources. The key resources that limit sensing precision are the number of receptors on the cell surface, readout molecules inside the cell, and available chemical energy like ATP. The document argues that the optimal allocation of these limited cellular resources determines the fundamental precision limit of concentration measurements by cells of time-varying signals.Sticky bacteria and the growth of biofilms on surfaces - Rosalind Allen
Sticky bacteria and the growth of biofilms on surfaces - Rosalind AllenLake Como School of Advanced Studies
This document summarizes a study on how pre-formed bacterial aggregates affect biofilm development. Experiments tracking Pseudomonas aeruginosa biofilms in a flow cell showed that initial aggregates drastically change the final biofilm structure depending on competition levels. Computer simulations similarly found that aggregates can outcompete surrounding single cells at high competition due to better nutrient access. Being in an aggregate is disadvantageous at low competition due to nutrient limitations. The findings have implications for biofilm shape, evolution, and the potential for cooperative behavior within aggregates.Stacking the odds for Golgi cisternal maturation - Somya mani
The document discusses a model of Golgi cisternal maturation, which is the process by which cargo moves through the Golgi apparatus. The model includes three steady states - static, balanced, and vesiculating - that depend on the rates of homotypic vesicle fusion and budding. Simulation results found the vesiculating state, where cisternae constantly form and disassemble, occurred 61% of the time and best matched current understanding of Golgi cisternal maturation.

Genetic switch between redundancy and synergy in a multicellular gene express...Lake Como School of Advanced Studies
This document summarizes research on the genetic encoding of environmental information by neurons in C. elegans. It finds that under normal conditions, the neurons ADF, ASI and NSM redundantly encode information about food levels in a redundant coding strategy. However, without the gene daf-7, this switches to a synergistic coding strategy where the neurons provide unique information. The redundancy provided by daf-7 helps maintain robust encoding and allows the worm to better regulate its lifespan in response to environmental food levels. The study uses imaging and information theory to analyze the coding strategies and how disrupting different genes like daf-7 and tph-1 impact the redundancy vs synergy of the neuronal encoding.ELUDING CATASTROPHIC SHIFTS - Paula Villa Martín, Juan A.

ELUDING CATASTROPHIC SHIFTS - Paula Villa Martín, Juan A. Bonachela,, Simon A...Lake Como School of Advanced Studies
The document discusses catastrophic shifts, which are large, abrupt changes in a system towards a completely different state. Catastrophic shifts can affect ecosystems like lakes, coral reefs, and woodlands. They are characterized by jumps in time series data, bistability between alternative stable states, hysteresis, and other patterns. Catastrophic shifts can be first-order transitions, meaning they are abrupt and not easily reversible, unlike second-order transitions which are smooth and reversible. A simple deterministic equation and stochastic equation are presented as the simplest ways to model these types of shifts between states in systems. High diffusion and low noise in the equations result in behavior that is nearly deterministic and more smoothly reversible compared to low diffusion/high noise scenariosGene expression noise, regulation, and noise propagation - Erik van Nimwegen
Gene expression noise, regulation, and noise propagation - Erik van NimwegenLake Como School of Advanced Studies
This document discusses gene expression noise and stochasticity. It begins with an overview of the basic processes in gene expression and the differential equations that describe them. It then notes that in reality, the numbers of molecules involved are often low and subject to random fluctuations due to Brownian motion. This stochasticity means that gene expression occurs as a probabilistic process that can be modeled using the master equation and results in Poisson distributions. The document explores how mRNA and protein noise is propagated and amplified, and discusses experimental measurements of variability within and between cells in bacteria.A generalized receptor law governs phototaxis in the phytoplankton Euglena gr...

The document discusses a study that found a generalized receptor law governs phototaxis in the phytoplankton Euglena gracilis. The study used experiments and modeling to determine that phototactic behavior in Euglena gracilis follows a generalized receptor law, where phototactic potential is determined by a function of light intensity divided by a constant plus intensity. This receptor law provided good agreement with measured distributions of algae in experiments with different light intensities and qualities.Exploratory Adaptation in Large Random Networks - Hallel Schreier and Naama ...
Exploratory Adaptation in Large Random Networks - Hallel Schreier and Naama ...Lake Como School of Advanced Studies
This document summarizes research on exploratory adaptation in large random networks. It presents a model where a network of interacting elements can reorganize through random walks in interaction strengths to reach a stable state where global demand is satisfied. The model demonstrates that successful adaptation depends on network topology. Exploratory adaptation works best for scale-free networks with hubs having many outgoing connections. Hubs play a key role in the adaptation process, and removing hubs reduces the network's ability to adapt. Some results show adaptation is most effective for scale-free topologies with large hubs and less effective for networks with binomial or exponential degree distributions.Reciprocity between robustness and plasticity as a universal quantitative law...
Reciprocity between robustness and plasticity as a universal quantitative law...Lake Como School of Advanced Studies
The document discusses a quantitative law of reciprocity between robustness and plasticity in biology. It presents evidence that more robust circadian rhythms and oscillatory dynamics demonstrate greater plasticity in response to environmental changes. This reciprocity relationship holds across different levels of biological organization, from molecular oscillations to spatial and temporal pattern formation. The proposed mechanism involves adaptation on a limit cycle via a buffer molecule, allowing robustness of a key parameter like period while permitting plasticity in other parameters like phase.Exploratory Adaptation in Random Networks - Naama Brenner
1. Gene regulatory networks have properties that enable exploratory adaptation, such as context-dependent binding and alternative splicing, that allow for a large number of expression patterns.
2. A theoretical model of a random network model with a feedback stress signal driving exploratory dynamics demonstrates how convergence to a stable phenotype is possible through a "drive reduction" principle without selection.
3. While convergence is possible, it is non-universal and depends on network properties like connection sparsity; the model shows how exploratory dynamics in gene expression can produce individual cellular adaptation within a few generations to unforeseen challenges.

Kuramoto dynamics, glassy synchronization and rare regions in the human conne...Lake Como School of Advanced Studies
The document discusses the Kuramoto model of synchronization and its application to modeling the human connectome. It finds that the connectome exhibits a hierarchical synchronization process, with local phase transitions leading to an intermediate synchronized phase. This behavior is also seen in hierarchical modular network models of the connectome. Both the real connectome data and model networks show switching or "up and down" states of metastability in the intermediate synchronization phase.Viewers also liked (20)

Metadynamics
Metadynamics is a computer simulation method in computational physics, chemistry, and biology. It is used to estimate the free energy and other state functions of a system, where ergodicity is hindered by the form of the system's energy landscape.
A statistical physics approach to system biology
- Systems biology is an interdisciplinary field that studies biological systems using a holistic approach, focusing on complex interactions within systems.
- Statistical physics approaches, like the Ising model of magnetism, can be applied to study biological systems and emergent phenomena. These simple models reveal how complex collective behavior can arise from local interactions.
- Critical phenomena observed in models like the Ising model provide insights into how biological systems may benefit from operating near a critical point, with long-range correlations and sensitivity to perturbations.

EEB 321 Community Ecology: phylogenetics lecture
This document outlines a lecture on community phylogenetics, which is the study of how evolutionary relationships among species affect community structure. It discusses classic theories of limiting similarity and how relatedness may influence communities. Contemporary approaches use phylogenetic tools to infer patterns of community assembly from evolutionary processes. The lecture also examines how phylogenetic distances can estimate species similarity and tests for phylogenetic over- and under-dispersion in communities. It further explores how differences in stabilizing niche differences versus fitness differences influence coexistence across evolutionary time.

Abstract:Reactive Power Optimization is a complex combinatorial optimization problem involving non-linear function having multiple local minima, non-linear and discontinuous constrains. This paper presents PS2O, which extends the dynamics of the canonical PSO algorithm by adding a significant ingredient that takes into account the symbiotic co evolution between species, Hybrid Evolutionary-Conventional Algorithm (HECA) that uses the abilities of evolutionary and conventional algorithm and Genetical Swarm Optimization (GSO), combines Genetic Algorithms (GA) and Particle Swarm Optimization (PSO).All the above said algorithms is used to overcome the Problem of premature convergence. PS2O, HECA , GSO is applied to Reactive Power Optimization problem and is evaluated on standard IEEE 57, practical 191 test Bus Systems. The results shows that all the three algorithms perform well in solving the reactive power problem and prevent premature convergence to high degree but still keep a rapid convergence. Of all the three PS2O has the edge in reducing the real power loss when compared to HECA & GSO.

Dr Lael Parrott at the Landscape Science Cluster Seminar, May 2009
This document summarizes how concepts from complex systems studies can inform natural resource management. It discusses how ecosystems and landscapes are complex systems with emergent properties arising from local interactions. Agent-based models are useful for modeling ecological complexity across scales. Examples shown include a model of grassland resilience under disturbance and the relationship between grazing and spatial complexity. Understanding community assembly is explored through a spatial model linking local communities. The document concludes that embracing complexity requires new tools like multi-scale models and monitoring to manage social-ecological systems.

The document discusses the CEECEC project and EJOLT project, which aim to teach ecological economics and political ecology concepts to environmental NGOs. It describes how NGOs can inform academic concepts through case studies, and how academic concepts like "ecological debt" have informed activist movements. It summarizes several case studies from the CEECEC project handbook that examine topics like mining, waste management, and protected areas from an ecological economics perspective. It also discusses how the concept of "degrowth" has moved from activist movements to academic research on transitioning to a steady-state economy in a socially and environmentally sustainable way.

Martin Hewitson is a physicist who has worked on projects including GEO600 calibration, LISA Pathfinder data analysis, and the LISA mission. In his lectures, he discusses why space-based gravitational wave observations are needed at lower frequencies than ground-based detectors can achieve. Lower frequencies allow observation of mergers of larger black hole and neutron star systems. The main challenges for low-frequency detection are isolating test masses from external forces and displacements, which is achieved through free-fall in space versus suspended masses on the ground. LISA will use interferometry between test masses in separate spacecraft to precisely measure gravitational waves.Space based Gravitational Wave Observations II - M Hewitson
The document discusses the Laser Interferometer Space Antenna (LISA) mission and its goal of achieving a strain sensitivity of around 10^-20 1/√Hz to measure distance changes of around 25 picometers per √Hz. It notes that frequency noise is currently around 0.9 millimeters per √Hz and aims to reduce this. LISA will consist of three spacecraft in an equilateral triangle formation with 2.5 million km sides to perform gravitational wave observations from space.
Space based Gravitational Wave Observations III - M Hewitson
The document summarizes the LISA Pathfinder mission to test technologies needed for the future LISA gravitational wave observatory. It describes how LISA Pathfinder contains two test masses inside a spacecraft to test keeping the masses in near-perfect free fall, similar to individual LISA spacecraft. The document outlines the various sensors and actuators used to control the test masses and spacecraft, the goal of demonstrating positioning of test masses to less than 10 picometers. It concludes by detailing the multi-step control process used to keep the test masses and spacecraft stabilized based on sensor readings.

Gravitational Waves and Binary Systems (2) - Thibault Damour
1) Gravitational waves are predicted by Einstein's theory of general relativity and are generated by accelerating masses like binary star systems.
2) Modeling the motion and gravitational wave emission of compact binary systems like neutron stars and black holes requires using techniques like post-Newtonian theory, effective field theory approaches, and numerical relativity simulations.
3) Understanding strong gravitational fields like those near black holes requires tools from general relativity like multipolar expansions, matched asymptotic expansions, and analytic continuation techniques.
Gravitational Waves and Binary Systems (1) - Thibault Damour
The document discusses gravitational waves and binary systems. It provides context on the history of gravitational wave detection, from Einstein's early work developing the theory of gravitational waves to Joseph Weber's pioneering efforts to detect them in the 1960s. It also summarizes the development of laser interferometer gravitational wave detectors by researchers in the US, Germany, Italy, and the UK beginning in the 1970s and 1980s. Key detections by LIGO and Virgo are noted, including GW150914 in 2015.

The document discusses econophysics and the instability of the financial system caused by credit risk. It outlines the topics to be covered, including a structural model of credit risk, numerical simulations, and a random matrix approach. The conclusions discuss how risk reduction through diversification in credit portfolios is limited by correlations between credit exposures and the presence of jumps in the economic variables modeling the credit risks. Large portfolios do not necessarily converge to a Gaussian loss distribution due to these effects.Econophysics VI: Price Cross-Responses in Correlated Financial Markets - Thom...

1) The document analyzes price formation and cross-responses between correlated financial markets using empirical data from NASDAQ stocks. It finds long-memory correlations between the trades and prices of different stocks.
2) Specifically, it measures the cross-response of one stock's price changes to the trades of other stocks, and the cross-correlation between stocks' trade signs. It finds these cross-responses and cross-correlations decay slowly over time, indicating long-range correlations.
3) Averaging the cross-responses and cross-correlations across stocks reduces noise and more clearly reveals their long-memory nature. The analysis provides evidence that liquidity and trading in one stock can have prolonged impacts on price formationEconophysics V: Market States and Subtleties of Correlations - Thomas Guhr

This document discusses market states and correlations between financial time series. It begins by introducing the Epps effect, where measured correlations decrease with smaller time intervals, and describes compensating for this using asynchronity and tick size corrections. Non-Gaussian dependencies are then covered, showing correlations can misrepresent relationships. Market states are identified using similarity measures between correlation matrices over time. Eight distinct market states are found for the US market between 1992-2010 based on industrial sector correlations.More from Lake Como School of Advanced Studies (20)

Deep Behavioral Phenotyping in Systems Neuroscience for Functional Atlasing a...
Functional Magnetic Resonance Imaging (fMRI) provides means to characterize brain activations in response to behavior. However, cognitive neuroscience has been limited to group-level effects referring to the performance of specific tasks. To obtain the functional profile of elementary cognitive mechanisms, the combination of brain responses to many tasks is required. Yet, to date, both structural atlases and parcellation-based activations do not fully account for cognitive function and still present several limitations. Further, they do not adapt overall to individual characteristics. In this talk, I will give an account of deep-behavioral phenotyping strategies, namely data-driven methods in large task-fMRI datasets, to optimize functional brain-data collection and improve inference of effects-of-interest related to mental processes. Key to this approach is the employment of fast multi-functional paradigms rich on features that can be well parametrized and, consequently, facilitate the creation of psycho-physiological constructs to be modelled with imaging data. Particular emphasis will be given to music stimuli when studying high-order cognitive mechanisms, due to their ecological nature and quality to enable complex behavior compounded by discrete entities. I will also discuss how deep-behavioral phenotyping and individualized models applied to neuroimaging data can better account for the subject-specific organization of domain-general cognitive systems in the human brain. Finally, the accumulation of functional brain signatures brings the possibility to clarify relationships among tasks and create a univocal link between brain systems and mental functions through: (1) the development of ontologies proposing an organization of cognitive processes; and (2) brain-network taxonomies describing functional specialization. To this end, tools to improve commensurability in cognitive science are necessary, such as public repositories, ontology-based platforms and automated meta-analysis tools. I will thus discuss some brain-atlasing resources currently under development, and their applicability in cognitive as well as clinical neuroscience.

Nucleophilic Addition of carbonyl compounds.pptx
Nucleophilic addition is the most important reaction of carbonyls. Not just aldehydes and ketones, but also carboxylic acid derivatives in general.
Carbonyls undergo addition reactions with a large range of nucleophiles.
Comparing the relative basicity of the nucleophile and the product is extremely helpful in determining how reversible the addition reaction is. Reactions with Grignards and hydrides are irreversible. Reactions with weak bases like halides and carboxylates generally don’t happen.
Electronic effects (inductive effects, electron donation) have a large impact on reactivity.
Large groups adjacent to the carbonyl will slow the rate of reaction.
Neutral nucleophiles can also add to carbonyls, although their additions are generally slower and more reversible. Acid catalysis is sometimes employed to increase the rate of addition.

EWOCS-I: The catalog of X-ray sources in Westerlund 1 from the Extended Weste...
Context. With a mass exceeding several 104 M⊙ and a rich and dense population of massive stars, supermassive young star clusters
represent the most massive star-forming environment that is dominated by the feedback from massive stars and gravitational interactions
among stars.
Aims. In this paper we present the Extended Westerlund 1 and 2 Open Clusters Survey (EWOCS) project, which aims to investigate
the influence of the starburst environment on the formation of stars and planets, and on the evolution of both low and high mass stars.
The primary targets of this project are Westerlund 1 and 2, the closest supermassive star clusters to the Sun.
Methods. The project is based primarily on recent observations conducted with the Chandra and JWST observatories. Specifically,
the Chandra survey of Westerlund 1 consists of 36 new ACIS-I observations, nearly co-pointed, for a total exposure time of 1 Msec.
Additionally, we included 8 archival Chandra/ACIS-S observations. This paper presents the resulting catalog of X-ray sources within
and around Westerlund 1. Sources were detected by combining various existing methods, and photon extraction and source validation
were carried out using the ACIS-Extract software.
Results. The EWOCS X-ray catalog comprises 5963 validated sources out of the 9420 initially provided to ACIS-Extract, reaching a
photon flux threshold of approximately 2 × 10−8 photons cm−2
s
−1
. The X-ray sources exhibit a highly concentrated spatial distribution,
with 1075 sources located within the central 1 arcmin. We have successfully detected X-ray emissions from 126 out of the 166 known
massive stars of the cluster, and we have collected over 71 000 photons from the magnetar CXO J164710.20-455217.

As the population is increasing and will reach about 9 billion upto 2050. Also due to climate change, it is difficult to meet the food requirement of such a large population. Facing the challenges presented by resource shortages, climate
change, and increasing global population, crop yield and quality need to be improved in a sustainable way over the coming decades. Genetic improvement by breeding is the best way to increase crop productivity. With the rapid progression of functional
genomics, an increasing number of crop genomes have been sequenced and dozens of genes influencing key agronomic traits have been identified. However, current genome sequence information has not been adequately exploited for understanding
the complex characteristics of multiple gene, owing to a lack of crop phenotypic data. Efficient, automatic, and accurate technologies and platforms that can capture phenotypic data that can
be linked to genomics information for crop improvement at all growth stages have become as important as genotyping. Thus,
high-throughput phenotyping has become the major bottleneck restricting crop breeding. Plant phenomics has been defined as the high-throughput, accurate acquisition and analysis of multi-dimensional phenotypes
during crop growing stages at the organism level, including the cell, tissue, organ, individual plant, plot, and field levels. With the rapid development of novel sensors, imaging technology,
and analysis methods, numerous infrastructure platforms have been developed for phenotyping.

The use of Nauplii and metanauplii artemia in aquaculture (brine shrimp).pptx
Although Artemia has been known to man for centuries, its use as a food for the culture of larval organisms apparently began only in the 1930s, when several investigators found that it made an excellent food for newly hatched fish larvae (Litvinenko et al., 2023). As aquaculture developed in the 1960s and ‘70s, the use of Artemia also became more widespread, due both to its convenience and to its nutritional value for larval organisms (Arenas-Pardo et al., 2024). The fact that Artemia dormant cysts can be stored for long periods in cans, and then used as an off-the-shelf food requiring only 24 h of incubation makes them the most convenient, least labor-intensive, live food available for aquaculture (Sorgeloos & Roubach, 2021). The nutritional value of Artemia, especially for marine organisms, is not constant, but varies both geographically and temporally. During the last decade, however, both the causes of Artemia nutritional variability and methods to improve poorquality Artemia have been identified (Loufi et al., 2024).
Brine shrimp (Artemia spp.) are used in marine aquaculture worldwide. Annually, more than 2,000 metric tons of dry cysts are used for cultivation of fish, crustacean, and shellfish larva. Brine shrimp are important to aquaculture because newly hatched brine shrimp nauplii (larvae) provide a food source for many fish fry (Mozanzadeh et al., 2021). Culture and harvesting of brine shrimp eggs represents another aspect of the aquaculture industry. Nauplii and metanauplii of Artemia, commonly known as brine shrimp, play a crucial role in aquaculture due to their nutritional value and suitability as live feed for many aquatic species, particularly in larval stages (Sorgeloos & Roubach, 2021).

Editor's Notes
- All the ecological patterns that I mentioned, those related to mass and abundance of species, can be obtained from the probability distribution P(n,m|A), representing the probability to find a species with abundance n and mass m in an ecosystem of area A. To characterize analytically this pdf, we formulated a model for the dynamics of an ecosystem subject to birth death and speciation, where we incorporated the following ingredients
