The document summarizes ecological succession and the key processes involved. It describes primary and secondary succession, with primary occurring in new areas and secondary following a disturbance. Succession proceeds through seral stages from pioneer to climax community. It provides examples of primary succession for bare rock, sand dunes, and ponds/lakes. The nutrient and energy cycles that drive ecological communities, including water, carbon, oxygen, and nitrogen are also overviewed.
I didn't make this powerpoint, this is from my IB Biology teacher but it's one of the only topics I actually really enjoyed sooo I'm putting it up, ^_^
• Nutrient cycles referred to as biogeochemical cycles
• Gaseous forms of carbon, oxygen, and nitrogen occur in the atmosphere and cycle globally
• Less mobile elements, including phosphorous, cycle on a more local level
• Still, gains and losses from outside of the ecosystem are generally small when compared to the rate at which nutrients are cycled within the system.

ABSTRACT- Fresh water resources are not unlimited. The high rate of increase of human population of Nepal and the
rapid rate of industrialization have created problems of disposal of waste water products. The domestic wastes, excretory
materials of both human and animals and industrial effluents are discharged into the nearly lakes, rivers, reservoirs and
tanks and even in the catchment area of the above water bodies. The undesirable substances are regularly mixed into the
water of pond through surface run-off that degrades the water quality. Since last several years, there have been added an
array of agricultural pesticides and insecticides, which are further seriously aggravating the problem of pollution both for
public health and aquaculture. The detailed information of water quality and status of affected living organisms of water
bodies are necessary for the implementation of any management plan. The present investigation encompasses on plankton
identifying the ecological quality of Chhapakaiya pond Birgunj, Nepal. Seasonal sampling from all the sampling sites (site
A, B, C, D) in winter, summer and rainy season for period of 12 months (November 2014 – October 2015) at 9:00-11: 00
AM. A total of 27 taxa from different classes of zooplankton were reported. The zooplanktons were reported to be
maximum (774.4 unit/L) during summer and minimum (539.2 unit/L) during the rainy season in Chhapakaiya pond.
Key-words- Zooplankton, Biological productivity, Habitat degradation
In terms of biomass, the greatest migration in the world is the migration of Zooplankton .
Zooplankton migration is different because it moves up and down through the ocean's depths rather than traversing a landscape.
Nutrient cycling is one of the most important processes that occur in an ecosystem. The nutrient cycle describes the use, movement, and recycling of nutrients in the environment.

Elevating Tactical DDD Patterns Through Object CalisthenicsDorra BARTAGUIZ
After immersing yourself in the blue book and its red counterpart, attending DDD-focused conferences, and applying tactical patterns, you're left with a crucial question: How do I ensure my design is effective? Tactical patterns within Domain-Driven Design (DDD) serve as guiding principles for creating clear and manageable domain models. However, achieving success with these patterns requires additional guidance. Interestingly, we've observed that a set of constraints initially designed for training purposes remarkably aligns with effective pattern implementation, offering a more ‘mechanical’ approach. Let's explore together how Object Calisthenics can elevate the design of your tactical DDD patterns, offering concrete help for those venturing into DDD for the first time!

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

Pushing the limits of ePRTC: 100ns holdover for 100 daysAdtran
At WSTS 2024, Alon Stern explored the topic of parametric holdover and explained how recent research findings can be implemented in real-world PNT networks to achieve 100 nanoseconds of accuracy for up to 100 days.
2. Succession
• PRIMARY succession
– Development of a community in an area that has
not supported life before.
• Requires the building of soil by PIONEER PLANTS
– Small fast-growing & fast-reproducing plants
– Lichen, moss, crabgrass, plankton
3. Primary succession
• Seral stages
– Developmental stages of an environment
– Ecological communities that succeed one
another in the biotic development of an area
– Species will eventually be replaced by
successive species based on conditions such as
Soil quantity Sunlight
Soil type Water
4. Seral stages
• Can be determined by an index species
• Index species Definition
– Species that are used as a reference point to
indicate relative placement in an ecosystem
5. Primary succession
• Climax Community
– Will be established eventually
– Community will prevail unless the area is
disturbed again
– Hardwood trees (maple, beech, birch)
6. Examples of Primary Succession
• Bare Rock Succession
• Sand Dune Succession
• Pond/Lake Succession
7. Bare rock succession
• Pioneer Plants:
– Lichens
Help break down rocks
Adds humus for
new soil building
What’s humus?
Substance that provides nutrients
Increases the ability of soil to retain H2O
8. Bare rock succession
• Seral stages:
– Mosses/fern
– Grasses/weeds
– Bushes
– Softwood trees
• Each stage paves the way for the next stage
9. Bare rock succession
• Climax community
– Hardwood trees
• Species of plant remain constant for a long
period of time until a disturbance occurs
10. Lichen
Hardwood
Softwood
trees
Bushes trees
Mosses, Grasses,
ferns weeds
Bare rocks
11.
12. Sand dune succession
• Pioneer plants:
– Beach grass
• Roots stabilize the sand
• Humus is added
to the foredune
– An area directly
behind the beach
13. Sand dune succession
• Seral stages
– Cottonwood
– Pines
– Oaks
• Continue to add
humus and shade
to the soil
17. Pond/lake succession
• Pioneer plants/organisms
– Microscopic plants and animals
• Phytoplankton - producers
• Zooplankton - consumers
• Found in
open water
• Humus is added
and soil develops
18. Pond/lake succession –
Seral stages
• Rooted submerged zone
– Closer to the shore
– Light penetrates all the way to the bottom so
young plants can grow
– Algae/Kelp
19. Pond/lake succession –
Seral stages
• Rooted floating zone
– Rooted in the bottom and leaves float on the
surface
– Water lilies
• Emergent zone
– Very shallow water
– Rooted in the bottom and
extend through the surface
– Cattails
22. Process of lake/pond succession
• As the plants die and as sediment washes in
from the surrounding land the lake (pond)
fills-in
• First the open water zone disappear
• Then the rooted submerged zone,
• Then the rooted floating zone,
• Then the emergent zone
23. Process of lake/pond succession
• Succession of an open field now takes place
(grasses and weeds, bushes, softwood trees,
finally hardwood trees)
• Climax community will depend on the biome
the lake (pond) was in.
32. Energy Flow
• Producers have the most energy.
• As an organism eats the next, available energy
decreases.
• Only 10% is passed on to the next trophic
level. (Ten Percent Law)
• What happens to the other 90%?
– Transferred as heat to the environment
33.
34. Pyramid of Energy
• A measure of the
amount of energy
available in each
trophic level
35. Ecosystem Recycling
• All molecules are recycled naturally in the
environment through a biogeochemical cycle.
• Biogeochemical cycle
– Movement of elements through various
compartments (at least one being biological).
– Water cycle
– Carbon/oxygen cycle
– Nitrogen cycle
36. Water Cycle
• Movement of water through various reservoirs
• Precipitation
– Water falling from the atmosphere to the ground
• Transpiration
– Water entering the atmosphere from plants
• Respiration
– Water entering the atmosphere from animals
• Evaporation
– Water entering the atmosphere through a phase change
(liquid to gas)
37. Water Cycle
• Absorption
– Water taken in by a plant
• Urination
– Water added to the ground by an animal
• Runoff/Seepage
– Excess water entering land or another body of water
• Aquifer/Groundwater
– Underground water stored in porous rocks
41. Carbon/Oxygen Cycle
• Movement of organic compounds through
various reservoirs.
• Based on concepts of photosynthesis and
cellular respiration
• Photosynthesis
– Autotrophs used CO2 found in the atmosphere
and convert it into an organic compound C6H12O6
42. Carbon/Oxygen Cycle
• Respiration
– Hetertrophs consume the glucose and release carbon
compounds in the form of CO2 wastes
• Decomposition
– When detritivores feed off of the remains of dead
organisms
• Fossil fuel
– Formed from years of high temperature and pressure of
decaying, organic matter
• Combustion
– The burning of organic matter
45. Nitrogen Cycle
• Movement of nitrogen-containing compounds
(proteins, nucleic acids, atmospheric
nitrogen, urine, ammonia, nitrates and nitrites.)
• Cycle could not exist if it wasn’t for BACTERIA
• Ammonification
– Decomposition
– When detritivores feed off the remains of dead
organisms and convert protein and nucleic acids into
ammonia
46. Nitrogen Cycle
• Nitrification
– When bacteria convert ammonia into nitrates (NO3) and
nitrites (NO2)
• Absorption
– When plants take up nitrates and form amino acids which
consumers will acquire as protein
• Denitrification
– When bacteria break down nitrates and produce nitrogen
gas
47. Nitrogen Cycle
• Nitrogen Fixation
– When bacteria found on special plants
(legumes – beans, peas, alfalfa) converts
atmospheric nitrogen into ammonia.
– Lightning can also perform this process.
