S.eubayanus & reticulate evolution
Saccharomyces has become a model genus for evolution and genomics. Improvements in genome sequencing and isolation protocols will allow us to produce high-quality genome sequences for all the major populations and lineages. In the mean time, multilocus phylogenetic and population genetic approaches are helping classify our strain collection for population genomic studies. In this talk, I will introduce some of the advances we have made in the description of populations of the newly discovered species S. eubayanus, the wild stock of lager-brewing hybrids. Using a combined pipeline of population and phylogenetic studies, we have described two well-differentiated populations in Patagonia (Argentina), indicating that S. eubayanus is native. Although S. eubayanus may not be endemic to South America, it is likely native. Lager-brewing hybrids isolated in Europe showed shared alleles with the S. eubayanus population P-B (L) and had low genetic diversity, suggesting the S. eubayanus alleles involved in hybridization were drawn from a small subpopulation derived from P-B (L). From our Wild YEAST Program, a yeast isolation project conducted by undergraduate students and citizen scientists from across the world, we identified three new S. eubayanus strains from Sheboygan, WI (USA). In contrast to the clear population differentiation in Patagonia, the North American strains represent a recent and possibly transient admixture of the two Patagonian populations. To capture reticulation and summarize it in a phylogenetic framework, we combine state-of-the-art Bayesian methods with phylogenetic network analysis. Our findings support the hypothesis that genetically divergent microbes can produce rare but economically important hybrids when they migrate from their natural ecological context.

This document discusses a study investigating land use and water quality in the Wilgerfontein Catchment in Edendale, South Africa via analysis of E. coli levels. The study aimed to assess E. coli levels at different points along the river, identify potential land uses associated with E. coli counts, and examine relationships between E. coli, temperature, and pH. Water samples were collected from 10 sites along the river and analyzed for E. coli, pH, and temperature. Results showed highest E. coli counts downstream with elevated levels of pH and temperature. The study concludes land use impacts water quality in the river.

The document discusses the niche and habitat of bald eagles. Bald eagles prefer living near water bodies like seas, lakes, and rivers where they can hunt for fish and other animals. Their home ranges can vary significantly depending on food availability, but are usually between 1700 to 10,000 acres. Bald eagle populations were impacted by factors like habitat loss and degradation but have increased in recent years after protections.
Water pbl
There is not enough clean drinking water globally, leading to health issues. Half of hospital beds are occupied by people suffering from lack of safe water, and 2.2 million people die annually from water-related diseases. The US has safer drinking water than places like Afghanistan - 90% is safe in the US compared to just 25% in Afghanistan. Water is treated differently in the US through coagulation, sedimentation, filtration, and disinfection. Boiling water can make it safer by removing chemicals, and using a lid allows it to boil faster.

Aquaponics (environmental science)
Aquaponics is a sustainable food production system that combines aquaculture and hydroponics. It allows fish and plants to symbiotically support each other - the fish waste provides nutrients for the plants, and the plants help filter the water for the fish. Aquaponics systems can be simple backyard set-ups or more complex commercial operations. They provide a local source of both fish protein and vegetables while conserving water and working with natural nutrient cycles. Starting an aquaponics system requires setting up tanks for fish and plants, as well as pumps, tubing, and water testing equipment, with total start-up costs ranging from $300-700.
Macroinvertebrates (EEE)
The Department of Environmental Protection monitors stream quality in Pennsylvania to protect the state's air, land, and water from pollution. Macroinvertebrates are useful for assessing water quality as some are tolerant of pollution while others are not, so their presence indicates the stream's pollution levels. Their role in nutrient cycles also makes them important to the whole ecosystem.

Bio 2 bobcat for school
This document discusses the bobcat (Lynx rufus) including its habitat, diet, reproduction, mortality factors, and role in the food chain. It also examines how stream quality, soil conditions, and various types of pollution could positively or negatively impact bobcat populations by altering the ecosystem and food web. Key factors discussed include nutrient levels, dissolved oxygen, pH, temperature, and turbidity in streams as well as pH, phosphorus, nitrogen, and potash levels in soil.
Final presentation draft 3.14.14
This study examined the population densities of purple marsh crabs and cordgrass in three sites within South Carolina's ACE Basin estuary. Population surveys found varying densities of purple marsh crabs (6.67-25 burrows/m2) and cordgrass (219-270 stalks/m2) across sites. A correlational analysis showed a weak negative relationship between crab and cordgrass populations. Compared to an unhealthy marsh in Cape Cod, the ACE Basin sites showed equally healthy crab and cordgrass densities, suggesting crab overpopulation is not negatively impacting cordgrass there as was seen in Cape Cod. The study aims to establish a baseline of these populations for future monitoring.
Invasives
The document discusses the invasive zebra mussel species in the Great Lakes region. Some key points:
- Zebra mussels were first discovered in the Great Lakes in 1988 and have since spread to over 180 introduced species. They can cause major economic and ecological damage.
- They proliferate rapidly and can filter large volumes of water, affecting water clarity and passing pollutants up the food chain. Their sharp shells also pose hazards for recreation and infrastructure.
- Controlling and eradicating the mussels is challenging as they are tolerant of chemicals. Researchers are studying new control methods like bacteria that could provide environmentally-friendly solutions.
Initial Assessment Microcystin-RTMDW
This document summarizes a study on microcystin levels in raw and treated municipal drinking water sources in Alberta. Microcystin is a toxin produced by some cyanobacteria (blue-green algae) that can be harmful to human health. The study analyzed water samples from 18 municipalities over 10 weeks and found microcystin present in 67% of raw water samples, with concentrations up to 14.8 μg/L in some sources. Microcystin was detected less often and at lower levels in treated water, indicating conventional treatment removes some toxin. All samples complied with Health Canada guidelines. The study recommends further sampling of rural communities to fully evaluate microcystin occurrence in municipal surface drinking water supplies.
CWRA Presentation
On Monday, Crozier & Associates Partner and Senior Water Resources Engineer Nick Mocan presented alongside Dr. Kevin Stevens of Wilfrid Laurier University at the 2019 CWRA National Conference on how targeted vegetation plantings can be used to enhance water quality treatment in stormwater management facilities.
Their presentation covered the last 8 months of site visits, vegetation surveys, and water sampling at a stormwater management (SWM) pond near a subdivision in the Credit Valley Conservation Authority watershed. Dr. Stevens, an expert in wetland plant ecology, discussed the science behind how plants can contribute to water quality treatment, the types of vegetation found at the site, and preliminary water quality analysis results. Mocan drew on his expertise in stormwater management to review the impact of climate change on SWM facility inputs, hydrology, and hydraulics. Mocan also highlighted how this multi-disciplinary research can help stormwater facilities cope with the effects of a changing climate.
Preliminary results show that vegetation in the subject SWM pond is performing nutrient removal year-round, but that removal rates are diminished during colder periods. However, there appear to be increasing removal efficiencies as vegetation begins to re-establish itself. Vegetation surveys also noted that volunteer species are contributing to increased species richness, but these plants may not all be desirable.
The second stage of this project will involve developing targeted planting mixes based on local hydrologic, hydraulic, and environmental conditions. We anticipate these mixes will provide improved water quality treatment in SWM facilities, prevent incursions of invasive plant species, and contribute to the reduction of nutrient loading in urban stormwater that reaches lakes and streams.
Role and requirement of water
This document discusses the role and requirement of water for animals. It notes that water is essential but availability is limited due to poor management and waste. The importance of water is that even a 10% loss can be fatal, and it facilitates many critical functions in the body. Water requirements vary based on species, age, productivity, temperature, feed composition and more. Specific water needs are provided for various livestock like cattle, pigs, poultry and small ruminants.
White tailed deer Jesse Murray Pd. 4

Water quality data from a stream is analyzed, showing the stream has low pollution levels and is a healthy habitat for deer. Factors like nitrates, phosphates, pH, and dissolved oxygen are compared between the stream, marsh, and abandoned mine, finding the stream best supports the deer.
Freshwater Matters from the FBA
The document summarizes upcoming courses being offered by the Freshwater Biological Association (FBA), including a two-day course on identifying chironomid midge pupae to assess water quality. It also provides brief summaries of recent research articles covering topics like female sticklebacks preparing offspring for climate change, lawsuits to protect endangered freshwater fish species, and the potential of swamps to store large amounts of carbon. The bulletin aims to keep readers informed of current freshwater issues and research involving the FBA.
Abstract: Aquaponics and aquaculture going back to basics
Aquaponics systems often require fish that provide an important protein source, like tilapia, which increases costs and complexity through requirements for extensive services, permitting, and knowledge of fish aquaculture. However, using ornamental fish instead could increase the likelihood of project success as they are cheaper and easier to cultivate, feed, and provide waste. This study tested a backyard raft aquaponics system using goldfish or koi as the waste source, and found that koi provided better crop growth than goldfish, with no significant difference between using LED lights or sunlight.

1) The bobcat lives in dense vegetation with plenty of prey like rabbits, hares, birds, and rodents. It has one main den and several auxiliary dens in places like rock shelters, caves, hollow logs, and fallen trees.
2) Bobcats mate in late winter and gestation lasts 50-70 days, resulting in litters of 1-6 kittens. Kittens are weaned at around 2 months and begin hunting at 5 months.
3) Bobcats have a lifespan of 10-12 years. Their death rate is affected by hunting, ticks/mosquitoes, and avoiding humans by moving to less populated areas.

Minks live near bodies of water like rivers and lakes, where they prey on small animals. They mate between January to April and give birth to litters of 4-6 kits after a 50 day gestation. Their natural predators include coyotes, cats and owls. Minks typically live 3 years in the wild and are at risk of disease from bacteria. Their population is regulated by territorial aggression and conflict between individuals.

Dan Molloy - Zebra mussels presentation 9/12/11
Dan Molloy is a research scientist studying diseases in aquatic organisms like zebra mussels. Zebra mussels were accidentally introduced to North America in 1988 and have caused ecological, recreational, and industrial problems. Molloy discovered the bacteria Pseudomonas fluorescens CL145A is lethal specifically to zebra mussels when ingested. Laboratory and field tests showed it is an effective and environmentally-safe control method. However, more research is still needed to determine if it can be used in lakes and rivers for containment purposes.
Bioindicators in river ecosystems
This document provides a review of biomonitoring approaches and bioindicators used for river ecosystems. It discusses key concepts in biomonitoring and defines bioindicators. The most common bioindicators for rivers - periphyton, benthic macroinvertebrates, and fish - are described in detail. Their importance in river ecosystems and advantages for biomonitoring are highlighted. Commonly used biomonitoring approaches include diversity indices, biotic indices, multimetric indices, and functional trait approaches. Biotic indices and multimetric approaches are frequently applied to evaluate river health, but functional measures are increasingly used as a complementary approach. Recent research also demonstrates the potential of molecular techniques to enhance taxonomic

Water monitoring presentation
Monitoring natural waters provides important information about environmental health and human impacts. There are four main methods: visual surveys assess appearance and conditions; biological inventories examine macroinvertebrate diversity and pollution tolerance; water quality tests measure factors like pH, temperature, dissolved oxygen, and contaminants; and flow rate can be monitored. Together these methods generate data for understanding watersheds and informing management decisions.
Paper mill waste treatment
The document summarizes waste treatment and disposal practices in the pulp and paper industry. It describes how the paper manufacturing process generates hazardous waste in the forms of wastewater, solid waste, and gaseous emissions. The wastewater contains chemicals like Na2CO3 and chlorinated compounds, while solid waste includes lime mud and treatment sludges. The document outlines steps taken for environmental improvements like wastewater management and air pollution control. It also details the multi-stage treatment strategies used, including chemical precipitation, activated sludge processing, and air floatation to treat various waste streams.
plant indicators
Biological indicators like lichens can be used to monitor environmental conditions over time. Lichens are especially good indicators of air pollution levels as different lichen species have varying sensitivities. In polluted areas, fruticose lichens which are the most sensitive will disappear first, followed by foliose lichens, while crustose lichens are the most resistant. Studies tracking changes in lichen populations can determine how air pollution levels have changed in a given location.
Toxicological screening
Toxicity studies are important for developing new drugs and extending the use of existing drugs. They help determine the potential pharmacological effects and toxicity of new molecules in animals according to FDA guidelines. Toxicity tests examine adverse events like cancer, organ toxicity, and skin/eye irritation. They also help calculate the no observed adverse effect level dose for clinical trials. Acute, subchronic, and chronic toxicity studies in rodents and nonrodents are commonly used to identify target organs of toxicity and determine safe dosage levels over different time periods. Proper ethics approval is required before conducting any animal studies.
Bioindicators
Bioindicators are organisms, such as lichens,birds and bacteria, that are used to monitor the health of the environment. The organisms and organism associations are monitored for changes that may indicate a problem within their ecosystem. The changes can be chemical, physiological or behavioural. Bioindicators are relevant for Ecological health

EPA Marine Phytoplankton Fact Sheet
This plain English fact sheet outlines the work done by the EPA in monitoring phytoplankton in Ireland's marine environment.
The EPA and the Marine Institute sample phytoplankton in estuaries and coastal waters around Ireland. They carry out sampling three times during the summer and once during winter. At each location, they take water samples just below the surface and above the seabed. They use the samples to assess how much phytoplankton is in the water and what species are present.
Phytoplankton are tiny, free-floating plants found suspended in the world’s oceans. Their name comes from Greek and means ‘plant drifter’. They are carried along by ocean currents and are usually found floating near the surface of the water. Like all plants they need sunlight to grow.
The main sources of nutrients around Ireland’s coast are discharges from wastewater treatment plants and run off from agricultural land. Phytoplankton in the estuaries and coastal waters around Ireland are monitored by the EnvironmentalProtection Agency (EPA) and the Marine Institute. They monitor phytoplankton to assess the quality (status) of our marine environment. They must do this as part of the requirements of the European Water Framework Directive.

This document discusses trophic ecology of fishes. It defines trophic ecology as the study of feeding relationships between organisms in communities and ecosystems. Food webs and food chains are used to represent trophic relationships. The trophic level of an organism indicates its position in a food chain. Fishes can be categorized based on their feeding habits as herbivorous, carnivorous, or omnivorous. Polyculture is discussed as an effective way to utilize different trophic niches. Methods for analyzing fish gut contents and food habits are also outlined. Common skeletal deformities in fishes are described which can be caused by genetic or environmental factors like pollution.
Role of Bio Markers In Water Monitoring
Biological monitoring uses organisms to assess environmental changes, especially those caused by human activity. Biomarkers are species that indicate ecosystem status through physiological or behavioral responses. Biomonitoring involves using indicator species like benthic macroinvertebrates, fish, algae, and plants to monitor water quality at individual, population, and community levels. Common biomonitoring techniques sample organisms or their tissues to detect genetic, reproductive, or other biological impacts from pollution.

Cluster Analysis of Aerobic Heterotrophic Bacteria from Clarias gariepinus an...Agriculture Journal IJOEAR
Abstract— Fish is a major source of protein for humans, and it is patronized by many in the tropics – where fishes can either be cultivated in the farms domestically or caught from open water bodies such as rivers, ponds and streams. These various sources of fishes and their attendant diversity of microorganisms particularly the bacteria make fishes as potential sources of pathogens. The maintenance of the microbiological quality of food and water is important to prevent waterborne/foodborne diseases in any community, thus the need for this study. A total of 14 samples of water at different points (upstream, midstream and downstream) and 50 samples of live fishes were used for this study. Each of the fish sample was bacteriologically analyzed using the pour-plate and spread plate techniques on culture media plates. And the isolated bacteria were identified using standard microbiological identification techniques. The water samples were subjected to physicochemical analysis to determine the physical and chemical properties of the water. The relatedness of the isolated bacteria was established using cluster analysis/dendogram. The highest bacterial count was obtained from downstream water sample (5.6x10 cfu/ml), indicating a possible pollution of water at this point. Both aerobic heterotrophic Gram positive and Gram negative bacteria were isolated. The Gram positive bacteria isolated include Staphylococcus lugdunensis, S. hominis, S. cohnii, Streptococcus pyogenes, S. pneumoniae, Kocuria varians while the Gram negative bacteria include Raoutella ornithinolytica, Klebsiella pneumoniae, Aeromonas hydrophila, A. veronii, Proteus vulgaris, Serratia fonticola, and Enterobacter gergoriae. Cluster analysis using dendrogram showed some degree of similarity among the different clusters of isolated bacteria. The result of this study presumptively shows that the water sample is polluted; and this in turn affects fresh water fishes in the river. Therefore the microbiological examination of the water at this study site is necessary for monitoring and controlling the quality and safety of the water for usage by the locals.Angelo Martello Pd 5

Cellular respiration has three parts: glycolysis, the citric acid cycle, and the electron transport chain. It occurs in the cytoplasm and mitochondria of cells. Glycolysis breaks down glucose and yields pyruvate, NADH, and ATP. The citric acid cycle further oxidizes pyruvate and produces more NADH, FADH2, ATP, and carbon dioxide. The electron transport chain uses NADH and FADH2 to power the synthesis of additional ATP. Without oxygen, lactic acid fermentation occurs, converting glucose to lactate and yielding less ATP.

Coniferous forests biome
Coniferous forests are dominated by cone-bearing evergreen trees adapted to cold climates. They have reduced leaf surfaces and remain green year-round to maximize growth during short northern seasons. Species like pines, spruces, and firs are common. Porcupines, squirrels, and birds consume their seeds. Owls and weasels control rodent populations. Moose are the largest browsing herbivores. Fires, though once suppressed, play a natural role in renewing coniferous forests.
Tundra biome
The Tundra biome has very harsh conditions, with frozen soil and low biodiversity. Summers are short, with temperatures barely rising above freezing. Plants must grow and reproduce rapidly in this short summer season. They have adaptations like small leaves and the ability to grow through snow. Animals also have adaptations like thick fur and changing fur color between seasons. Predator and prey populations fluctuate together based on the availability of food sources like lemmings.
Grassland
The grasslands biome is dominated by grasses and other herbaceous plants called forbs. It covers more of the Earth's surface than any other biome. North American grasslands can be divided into tallgrass, mixed grass, and shortgrass prairies depending on the average precipitation and height of the dominant grasses. While grasses remain green and growing in the spring and summer, they become brown and dried out in the autumn and winter. Grasslands support a diversity of primary consumers and provide habitat for species like bison, prairie dogs, meadowlarks and rattlesnakes. However, over 99% of North American grasslands have been converted to agricultural use like growing corn and wheat.
Desert
The North American deserts are located east of mountain ranges where moisture-laden winds drop their precipitation on the western slopes, creating rain shadows. These include the Sierra Nevada mountains, which block moisture from reaching deserts. North American deserts experience large temperature ranges from 20-110 degrees Fahrenheit but are generally dry, receiving less than 10 inches of annual precipitation. Vegetation and animals are limited by the arid conditions and low-nutrient soils. Common plant adaptations include shallow, widespread roots and fleshy stems for water storage. Many reptiles, including rattlesnakes, lizards and tortoises, are well-adapted to the desert climate through behaviors like burrowing and crepuscular activity patterns. After rare

Tropical rainforests power pt
1) Tropical rainforests have four distinct vegetation layers: the emergent layer, canopy layer, understory layer, and ground layer.
2) Trees in the rainforest have adaptations like buttress roots and drip tips to withstand the wet conditions.
3) Biodiversity is extremely high in the rainforest, with many species of plants, animals, birds, mammals, reptiles, amphibians, and arthropods adapted to life in the dense canopy.
Goldenrod galls
The document describes the goldenrod gall fly larva parasite-predator guild found on Canada goldenrod. It details how the gall fly larva initiates formation of ball galls by secreting a plant growth hormone. The gall provides shelter and food for the larva. However, some gall fly larvae are parasitized by wasp larvae that eventually kill the fly larva. Other insect larvae like the tumbling flower beetle may also inhabit the gall, preying on its other occupants. A guild is formed by organisms that are tightly interconnected and dependent on each other for survival.

Mobile Security Framework - MobSF is a free and open source automated mobile application security testing environment designed to help security engineers, researchers, developers, and penetration testers to identify security vulnerabilities, malicious behaviours and privacy concerns in mobile applications using static and dynamic analysis. It supports all the popular mobile application binaries and source code formats built for Android and iOS devices. In addition to automated security assessment, it also offers an interactive testing environment to build and execute scenario based test/fuzz cases against the application.
This talk covers:
Using MobSF for static analysis of mobile applications.
Interactive dynamic security assessment of Android and iOS applications.
Solving Mobile app CTF challenges.
Reverse engineering and runtime analysis of Mobile malware.
How to shift left and integrate MobSF/mobsfscan SAST and DAST in your build pipeline.

Chris Jones, Director of Product Management at BrainChip , presents the “Temporal Event Neural Networks: A More Efficient Alternative to the Transformer” tutorial at the May 2024 Embedded Vision Summit.
The expansion of AI services necessitates enhanced computational capabilities on edge devices. Temporal Event Neural Networks (TENNs), developed by BrainChip, represent a novel and highly efficient state-space network. TENNs demonstrate exceptional proficiency in handling multi-dimensional streaming data, facilitating advancements in object detection, action recognition, speech enhancement and language model/sequence generation. Through the utilization of polynomial-based continuous convolutions, TENNs streamline models, expedite training processes and significantly diminish memory requirements, achieving notable reductions of up to 50x in parameters and 5,000x in energy consumption compared to prevailing methodologies like transformers.
Integration with BrainChip’s Akida neuromorphic hardware IP further enhances TENNs’ capabilities, enabling the realization of highly capable, portable and passively cooled edge devices. This presentation delves into the technical innovations underlying TENNs, presents real-world benchmarks, and elucidates how this cutting-edge approach is positioned to revolutionize edge AI across diverse applications.Harnessing the Power of NLP and Knowledge Graphs for Opioid Research

- 8. What can the biota (living things) tell us?
- 9. What can the biota (living things) tell us? There are organisms that are very tolerant of poor water quality. If they are present, and other species, which require high water quality are absent, then the quality of the water is poor.
- 10. What can the biota (living things) tell us? If those species that require high water quality are present, then there is nothing in the water that is harmful to them. The water quality must be high.
- 11. What can the biota (living things) tell us? If those species that require high water quality are present, then there is nothing in the water that is harmful to them. The water quality must be high. *Even if those species that require high water quality are present, those that tolerate poor quality will be present too.
