Partnering on CWR research at three scales: commonalities for successCWR Project
The potential for crop wild relatives (CWR) to contribute to crop improvement is growing due to improvements in information on species and their diversity, advancements in breeding tools, and the growing need for exotic genetic diversity to address compounding agronomic challenges. As wild plants, CWR are subject to a myriad of human caused threats to natural ecosystems, and their representation ex situ is often far from comprehensive. Ex situ conservation of many of these wild plants is also technically challenging, particularly in an environment of insufficient resources. Enhancing conservation, availability, and access to CWR requires a spectrum of action spanning basic and applied research on wild species to inform on-the-ground collecting, ex situ maintenance, and germplasm utilization. The development of effective information channels and productive partnerships between diverse organizations are essential to the success of these actions. Here we report on a spectrum of CWR activities involving broad partnerships, at three levels: a) the collaborative compilation and distribution on over 5 million occurrence data records on the CWR of major food crops, b) the analysis of conservation concerns and genetic resources potential of the CWR of potato, sweetpotato, and pigeonpea, and c) ongoing efforts to map the diversity and conservation concerns for CWR in the USA. Although differing in scales and depth of collaborations, the success of these initiatives are largely due to commonalities in research orientation, e.g., inclusiveness, offering clear incentives for involvement, and service providing to the crop science community.

Understanding properties of food webs, such as their topology or stability, and the rules underlying food web structure, has been a key issue in ecology for now more than half a century. Because obtaining data on food webs has long been a hard task by itself, this research field has progressed slowly, and its dynamical aspects have seldom been empirically considered. However, technical advances, like next generation sequencing or the possibility of retrieving past ecosystems in sediment cores, have paved the way for massive data and the analysis of time series on food webs, while new models allow better predictions about food web dynamics. Making use of such existing data sets, this working group aimed at assessing the effects of biological invasions on food web topology, the fluxes of energy and nutrients throughout the network, and its ultimate effects on biodiversity. The working group has provided an integrative view on this topic, simultaneously tackling empirical, theoretical and applied aspects of biological invasions in food webs. Obvious applications will arise both from the numerous transports of invasive species and from the reshuffling of natural communities that is expected under global change scenarios. The working group comprised theoreticians and empiricists, biological invasion specialists as well as food web and host-parasite network experts, and benefited from existing experience in the field of ecoinformatics and massive data management in ecology.
THE EFFECTS OF CLEARCUT SIZE ON THE BIRD COMMUNITY IN THE SECOND COLLEGE GRANTjoshmooney
Abstract. This study examines the effects of forest opening (clearcut) size on the surrounding forest-bird community with the objective of offering management suggestions for foresters who employ the clearcut method. I hypothesized that large and small clearcuts would have different effects on the forest-bird assemblage associated with each. I used the point-count method to assess bird abundance in clearcuts, on the edges, and 100 m into the forest from the edges of large and small clearcuts. I found that Neotropical migrant birds and forest-interior birds were the most affected by large clearcuts showing significantly lower abundance in forest areas 100 m from large clearcut edges than in forest areas 100 m from small clearcuts. Edge-open birds were more abundant in large clearcut openings and edges than in small clearcut openings and edges. Blue jays (an avian nest predator) were more abundant on the edges of large clearcuts than on the edges of small clearcuts. A recent study found that forest-interior bird abundance levels off after 100 m distance from small (0.4 ha) forest openings. This result combined with my findings suggest that small openings in the Second College Grant represent less of a disturbance to Neotropical migrants and forest-interior birds. Additionally, given higher abundances of an avian nest predator in large clearcuts, reproductive success could be much lower in areas associated with large clearcuts. Some species such as the White-throated Sparrow (Zonotrichia albicollis), however preferred large clearcuts suggesting that there are some benefits to overall bird abundance by including large clearcuts in a managed landscape.
predator prey interactions are of great importance in the agro ecosystems. insects being the largest group of arthropods have a major role in designing various management strategies against different crop pests. these interactions influence the structure and dynamics of an agro ecosystem.

Multi-source connectivity as the driver of solar wind variability in the heli...Sérgio Sacani
The ambient solar wind that flls the heliosphere originates from multiple
sources in the solar corona and is highly structured. It is often described
as high-speed, relatively homogeneous, plasma streams from coronal
holes and slow-speed, highly variable, streams whose source regions are
under debate. A key goal of ESA/NASA’s Solar Orbiter mission is to identify
solar wind sources and understand what drives the complexity seen in the
heliosphere. By combining magnetic feld modelling and spectroscopic
techniques with high-resolution observations and measurements, we show
that the solar wind variability detected in situ by Solar Orbiter in March
2022 is driven by spatio-temporal changes in the magnetic connectivity to
multiple sources in the solar atmosphere. The magnetic feld footpoints
connected to the spacecraft moved from the boundaries of a coronal hole
to one active region (12961) and then across to another region (12957). This
is refected in the in situ measurements, which show the transition from fast
to highly Alfvénic then to slow solar wind that is disrupted by the arrival of
a coronal mass ejection. Our results describe solar wind variability at 0.5 au
but are applicable to near-Earth observatories.
Cancer cell metabolism: special Reference to Lactate PathwayAADYARAJPANDEY1
Normal Cell Metabolism:
Cellular respiration describes the series of steps that cells use to break down sugar and other chemicals to get the energy we need to function.
Energy is stored in the bonds of glucose and when glucose is broken down, much of that energy is released.
Cell utilize energy in the form of ATP.
The first step of respiration is called glycolysis. In a series of steps, glycolysis breaks glucose into two smaller molecules - a chemical called pyruvate. A small amount of ATP is formed during this process.
Most healthy cells continue the breakdown in a second process, called the Kreb's cycle. The Kreb's cycle allows cells to “burn” the pyruvates made in glycolysis to get more ATP.
The last step in the breakdown of glucose is called oxidative phosphorylation (Ox-Phos).
It takes place in specialized cell structures called mitochondria. This process produces a large amount of ATP. Importantly, cells need oxygen to complete oxidative phosphorylation.
If a cell completes only glycolysis, only 2 molecules of ATP are made per glucose. However, if the cell completes the entire respiration process (glycolysis - Kreb's - oxidative phosphorylation), about 36 molecules of ATP are created, giving it much more energy to use.
IN CANCER CELL:
Unlike healthy cells that "burn" the entire molecule of sugar to capture a large amount of energy as ATP, cancer cells are wasteful.
Cancer cells only partially break down sugar molecules. They overuse the first step of respiration, glycolysis. They frequently do not complete the second step, oxidative phosphorylation.
This results in only 2 molecules of ATP per each glucose molecule instead of the 36 or so ATPs healthy cells gain. As a result, cancer cells need to use a lot more sugar molecules to get enough energy to survive.

introduction to WARBERG PHENOMENA:
WARBURG EFFECT Usually, cancer cells are highly glycolytic (glucose addiction) and take up more glucose than do normal cells from outside.
Otto Heinrich Warburg (; 8 October 1883 – 1 August 1970) In 1931 was awarded the Nobel Prize in Physiology for his "discovery of the nature and mode of action of the respiratory enzyme.
WARNBURG EFFECT : cancer cells under aerobic (well-oxygenated) conditions to metabolize glucose to lactate (aerobic glycolysis) is known as the Warburg effect. Warburg made the observation that tumor slices consume glucose and secrete lactate at a higher rate than normal tissues.

Earliest Galaxies in the JADES Origins Field: Luminosity Function and Cosmic ...Sérgio Sacani
We characterize the earliest galaxy population in the JADES Origins Field (JOF), the deepest
imaging field observed with JWST. We make use of the ancillary Hubble optical images (5 filters
spanning 0.4−0.9µm) and novel JWST images with 14 filters spanning 0.8−5µm, including 7 mediumband filters, and reaching total exposure times of up to 46 hours per filter. We combine all our data
at > 2.3µm to construct an ultradeep image, reaching as deep as ≈ 31.4 AB mag in the stack and
30.3-31.0 AB mag (5σ, r = 0.1” circular aperture) in individual filters. We measure photometric
redshifts and use robust selection criteria to identify a sample of eight galaxy candidates at redshifts
z = 11.5 − 15. These objects show compact half-light radii of R1/2 ∼ 50 − 200pc, stellar masses of
M⋆ ∼ 107−108M⊙, and star-formation rates of SFR ∼ 0.1−1 M⊙ yr−1
. Our search finds no candidates
at 15 < z < 20, placing upper limits at these redshifts. We develop a forward modeling approach to
infer the properties of the evolving luminosity function without binning in redshift or luminosity that
marginalizes over the photometric redshift uncertainty of our candidate galaxies and incorporates the
impact of non-detections. We find a z = 12 luminosity function in good agreement with prior results,
and that the luminosity function normalization and UV luminosity density decline by a factor of ∼ 2.5
from z = 12 to z = 14. We discuss the possible implications of our results in the context of theoretical
models for evolution of the dark matter halo mass function.

Observation of Io’s Resurfacing via Plume Deposition Using Ground-based Adapt...Sérgio Sacani
Since volcanic activity was first discovered on Io from Voyager images in 1979, changes
on Io’s surface have been monitored from both spacecraft and ground-based telescopes.
Here, we present the highest spatial resolution images of Io ever obtained from a groundbased telescope. These images, acquired by the SHARK-VIS instrument on the Large
Binocular Telescope, show evidence of a major resurfacing event on Io’s trailing hemisphere. When compared to the most recent spacecraft images, the SHARK-VIS images
show that a plume deposit from a powerful eruption at Pillan Patera has covered part
of the long-lived Pele plume deposit. Although this type of resurfacing event may be common on Io, few have been detected due to the rarity of spacecraft visits and the previously low spatial resolution available from Earth-based telescopes. The SHARK-VIS instrument ushers in a new era of high resolution imaging of Io’s surface using adaptive
optics at visible wavelengths.

4. Research Question: Do changing rates of Bruchid Beetle
predation have a significant effect on the survivorship and
equilibrium stage structure of A. humilis?
NULL HYPOTHESIS
• The population persistence
and equilibrium stage structure
of A. humilis is not strongly
affected by Bruchid Beetle
predation
• Leading eigenvalue and
eigenvector of the stage-
structured matrix will be
relatively similar with different
levels of predation
ALTERNATIVE HYPOTHESIS
• The population persistence
and equilibrium stage structure
of A. humilis is strongly
impacted by Bruchid Beetle
predation
• Leading eigenvalue and
eigenvector of the stage-
structured matrix will be
significantly different with
different levels of predation

fragment 3 as extracted from the Souza and Martins study.
The survivorship of seeds to seedlings (the box with an “x”)
was modified for our sensitivity analysis to summarize the
effect of varying rates of predation by Bruchid Beetles.
9. Key Concept: Eigenvalue
• A is a
matrix:
• V is a vector: • w is A x v:
• λ is a scalar: • w is λ x v:• V is a vector:
10. Calculating Eigenvalues
• Create the stage-structured
matrix
• Create an Index for seed
survival to seedling stage
class
• Calculate eigenvalues for
the index
11. … And plot!
Figure 2. Sensitivity analysis of seed survivorship on population growth rate. At eigenvalues smaller
than 1 the population is declining while at eigenvalues larger than 1 the population is growing. It
appears that the seed survivorship needs to be very small before the population will begin declining.
13. Eigenvector Analysis
Fragment 1 Fragment 3
Survivorship 0.01% 1% 0.01% 1%
Seed 98.03% 95.50% 99.61% 96.65%
Seedling 0.05% 2.48% 0.03% 1.62%
Juvenile 0.01% 0.39% ~0.00% 0.08%
Immature 0.24% 0.61% 0.22% 1.47%
Virgin 1.52% 0.85% ~0.00% ~0.00%
Reproductive 0.15% 0.17% 0.14% 0.17%
Table 2. Equilibrium stage structure
of the two populations of A. humilis
with a seed survivorship of 0.01%
and 1%. We see that as seed
survivorship increases, the proportion
of individuals in the seed stage class
decreases and the proportion of
individuals in the other stage classes
increases (except for the virgin stage
class in fragment 1).
14. Results
• Beetle predation needs to be relatively
high in fragment 1 and 3 to drive the two
populations of A. humilis to extinction
• Seed survivorship of 0.04% in
fragment 1 and 0.09% in fragment 2
• Higher levels of seed survivorship result
in a smaller proportion of seeds and a
larger proportion of individuals in all
other stage classes

15. Discussion
• Previous research has shown that A. humilis is more effective at
dispersing seeds in smaller fragments than most palms
• Higher survivorship of the seeds in the small (I) fragment
• Lower rates of predation correspond to a more diverse stage structure
(healthier population of A. humilis overall)
• Our findings (resilience of the population under high rates of seed
predation) support previous findings that palm populations are
generally quite resilient to beetle predation
16. Discussion – future work
• The stage structures in our analysis came from a study at a very specific
location in Northern Brazil
• Stage structure between fragment 1 and fragment 3 varied
markedly (high variability in stage-structured matrices of A.
humilis)
• Meta-sample the reproduction and fecundity of A. humilis throughout
Central and South America to better understand stage-structured
variability
• Conduct eigenvalues and eigenvectors for each sample
• Summarize the range and variance in potential predation rates that
could drive any local population of A. humilis extinct
