Significance Environmental temperatures drive major ecological processes, largely because the physiology of any organism depends on its temperature. For this reason, many animals behave in ways that prevent their body from fluctuating, even as climate changes dramatically. Using a combination computer simulations and controlled experiments, we show thermoregulation not only mean variance operative environmental but also spatial arrangement these temperatures. Our results have further...
Significance The salinity of freshwater ecosystems is increasing worldwide. Given that most organisms have no recent evolutionary history with high salinity, we expect them to a low tolerance elevated caused by road deicing salts, agricultural practices, mining operations, and climate change. Leveraging the results from network experiments conducted across North America Europe, showed salt pollution triggers massive loss important zooplankton taxa, which led increased phytoplankton biomass...
The application of road deicing salts in northern regions worldwide is changing the chemical environment freshwater ecosystems. Chloride levels many lakes, streams, and wetlands exceed chronic acute thresholds established by United States Canada for protection biota. Few studies have identified impacts stream wetland communities none examined lake communities. We tested how relevant concentrations salt (15, 100, 250, 500, 1000 mg Cl- /L) interacted with experimental containing two or three...
The relationship between an island’s size and the number of species on that island—the island species–area (ISAR)—is one most well-known patterns in biogeography forms basis for understanding biodiversity loss response to habitat fragmentation. Nevertheless, there is contention about exactly how estimate ISAR influence three primary ecological mechanisms drive it — random sampling, disproportionate effects, heterogeneity. Key this estimates are often confounded by sampling measures (i.e.,...
Abstract Human‐induced salinization increasingly threatens inland waters; yet we know little about the multifaceted response of lake communities to salt contamination. By conducting a coordinated mesocosm experiment across 16 sites in North America and Europe, quantified zooplankton abundance (taxonomic functional) community structure broad gradient environmentally relevant chloride concentrations, ranging from 4 ca. 1400 mg Cl − L −1 . We found that crustaceans were distinctly more...
Abstract The quality of freshwater ecosystems is decreasing worldwide because anthropogenic activities. For example, nutrient over‐enrichment associated with agricultural, urban, and industrial development has led to an acceleration primary production, or eutrophication. Additionally, in northern areas, deicing salts that are evolutionary novel stressor have caused chloride levels many freshwaters exceed thresholds established for environmental protection. Even if excess nutrients road often...
Summary The application of deicing road salts began in the 1940s and has increased drastically regions where snow ice removal is critical for transportation safety. most commonly applied salt sodium chloride (NaCl). However, costs NaCl, its negative effects on human health, degradation roadside habitats driven agencies to seek alternative organic additives reduce rate NaCl or increase effectiveness. Few studies have examined aquatic ecosystems, but none explored potential impacts...
Abstract The salinization of freshwaters is a global threat to aquatic biodiversity. We quantified variation in chloride (Cl − ) tolerance 19 freshwater zooplankton species four countries answer three questions: (1) How much Cl present among populations? (2) What factors predict intraspecific tolerance? (3) Must we account for accurately community conducted field mesocosm experiments at 16 sites and compiled acute LC 50 s from published laboratory studies. found high multiple species, which,...
Most organisms experience environments that vary continuously over time, yet researchers generally study phenotypic responses to abrupt and sustained changes in environmental conditions. Gradual changes, whether predictable or stochastic, might affect differently than do changes. To explore this possibility, we exposed terrestrial isopods (Porcellio scaber) collected from a highly seasonal environment four thermal treatments: (1) constant 20°C; (2) 10°C; (3) steady decline 20° (4) stochastic...
Abstract As the numbers of chemical contaminants in freshwater ecosystems increase, it is important to understand whether interact ecologically ways. The present study investigated independent and interactive effects 2 that frequently co‐occur environments among higher latitudes, including a commonly applied insecticide (carbaryl) road salt (NaCl). hypothesis was addition either contaminant would result decline zooplankton, an algal bloom, subsequent both periphyton consumers.

Abstract Habitat heterogeneity is a primary mechanism influencing species richness. Despite the general expectation that increased should increase richness, there considerable variation in observed relationship, including many studies show negative effects of on One can create such disparate results predicted trade‐off between habitat area and heterogeneity, sometimes called area‐heterogeneity‐trade‐off ( AHTO ) hypothesis. The hypothesis predicts positive richness large habitats, but small...
Abstract Single‐lake studies offer an opportunity for understanding, predicting, and mitigating local or regional threats to lake ecosystems. Our goal was understand how concurrent environmental stressors such as climate change, eutrophication, salinization affect long‐term water quality. We report epilimnetic changes in 18 water‐quality parameters collected at seven sites from 1980 2016 Lake George, a large oligotrophic the Adirondack Park, New York, USA. Improvements deteriorations quality...
The global increase in the application rate of road salts such as sodium chloride (NaCl) has led to concern about their negative effects on roadside habitats and freshwater ecosystems. To reduce NaCl minimize ecological salts, transportation agencies are continuously seeking alternative magnesium (MgCl 2 ) organic additives beet juice distillation byproducts. Yet, there is remarkably little information how these salt alternatives affect aquatic communities, including mosquito populations....

In case, we report patient with treatment-resistant epilepsy GABRB3 genetic variant phenotype who was admitted for sepsis found to have significant thrombocytopenia clinical manifestations epistaxis easy bruising, which be due VPA use rather than secondary other pathologies. The patient's condition improved supportive treatment...
Human modification of landscapes has substantially altered the quality and quantity terrestrial subsidies to freshwater ecosystems. The same modifications frequently lead addition chemical contaminants environments. Both types environmental change can alter abundance species ecological interactions that affect entire communities. We examined how variation tree litter inputs interacts with road salt deicers, which are an increasingly common contaminant in northern latitudes. Based on studies...
Abstract Increased dispersal of individuals among discrete habitat patches should increase the average number species present in each local patch. However, experimental studies have found variable effects on richness. Priority effects, predators, and heterogeneity been proposed as mechanisms that limit effect size a patch could affect how regulates able to persist. We investigated whether interacted with rate habitats. hypothesized increased rates would positively richness more small...
Prey often reduce predation risk at the cost of lower resource intake. The cumulative effects such tradeoffs can alter allocation, demography and evolutionary processes. We show how accumulation reduces growth rate wild North American porcupines Erethizon dorsatum , simulate three responses related to lifetime reproductive success. Individual experiencing from fishers Pekania pennanti grew slower gave birth fewer offspring. Simulations that alone lead population declines, a female replace...
The shape of the species–area relationship (SAR) often varies with amount available energy; SARs from high‐energy habitats typically have higher intercepts and steeper slopes than low‐energy habitats. Such patterns are assumed to result a shift in mechanisms coexistence between high low energy However, plausible but unexplored alternative mechanism emerges proportional sampling, if there simply more individuals larger or productive habitats, without need invoke differing mechanisms. Here, we...
Most studies of home ranges occur over short time periods and may not represent the spacial requirements long-lived organisms such as turtles. Home 18 individual Blanding’s Turtles (Emydoidea blandingii) were measured using minimum convex polygons. Annual space use was compared to multi-year by We found a significant difference between annual range size (25.5 hectares) (two six years) (65.7 hectares; n = 18, P 0.016). Caution should be employed when making management decisions based on...
