Practical considerations for trace DNA recovery and detection of an invasive reptile across different deposition scenariosNARA Subscribed
Trace DNA detection methods are increasingly applied to biomonitoring, in conservation, biosecurity, and wildlife forensic sciences. Reptiles are high risk invasive alien species that can cause damaging environmental impacts, yet the dynamics around terrestrial reptile DNA deposition and subsequent detection are poorly understood. Concerns around the role of the pet trade in introducing key reptile pests have resulted in calls...

Temperature dependence of leaf breakdown in streams differs between organismal groups and leaf speciesNARA Subscribed
Increased temperatures are altering rates of organic matter (OM) breakdown in stream ecosystems with implications for carbon (C) cycling in the face of global change. The metabolic theory of ecology (MTE) provides a framework for predicting temperature effects on OM breakdown, but differences in the temperature dependence of breakdown driven by different organismal groups (i.e., microorganisms vs. invertebrate detritivores) an...
The Toxicology Investigators Consortium 2022 Annual ReportNARA Subscribed
The Clean Water Act (CWA) of 1972 regulates water quality in U.S. inland waters under a system of cooperative federalism in which states are delegated implementation and enforcement authority of CWA provisions by the U.S. Environmental Protection Agency. We leveraged heterogeneity in state implementation of the CWA to evaluate the efficacy of its nonpoint source provisions in reducing nutrient pollution, the leading cause of w...
Is the future female for turtles? Climate change and wetland configuration predict sex ratios of a freshwater speciesNARA Subscribed
Climate change and land‐use change are leading drivers of biodiversity decline, affecting demographic parameters that are important for population persistence. For example, scientists have speculated for decades that climate change may skew adult sex ratios in taxa that express temperature‐dependent sex determination (TSD), but limited evidence exists that this phenomenon is occurring in natural settings. For species that are...
Food insecurity and disasters: predicting disparities in total and first-time food pantry visits during the COVID-19 pandemicNARA Subscribed
In the U.S. state of Arizona, nearly one-third of households experienced food insecurity during the COVID-19 pandemic, an increase from one-fourth of households before the pandemic. Previous research on food insecurity in the wake of natural and human-instigated disasters demonstrates that groups vulnerable to food insecurity before a disaster are more susceptible to food insecurity during and after that disaster; however, les...
Analyses of three‐dimensional species associations reveal departures from neutrality in a tropical forestNARA Subscribed
The study of community spatial structure is central to understanding diversity patterns over space and species co‐occurrence at local scales. Although most analytical approaches consider horizontal and vertical dimensions separately, in this study we introduce a three‐dimensional spatial analysis that simultaneously includes horizontal and vertical species associations. Using tree census data (2000–2016) and allometries from t...
Growing‐season warming and winter soil freeze/thaw cycles increase transpiration in a northern hardwood forestNARA Subscribed
Climate models project higher growing‐season temperatures and a decline in the depth and duration of winter snowpack throughout many north temperate ecosystems over the next century. A smaller snowpack is projected to induce more frequent soil freeze/thaw cycles in winter in northern hardwood forests of the northeastern United States. We measured the combined effects of warmer growing‐season soil temperatures and increased win...
TRY plant trait database – enhanced coverage and open accessNARA Subscribed
Plant traits—the morphological, anatomical, physiological, biochemical and phenological characteristics of plants—determine how plants respond to environmental factors, affect other trophic levels, and influence ecosystem properties and their benefits and detriments to people. Plant trait data thus represent the basis for a vast area of research spanning from evolutionary biology, community and functional ecology, to biodivers...
Drier tropical forests are susceptible to functional changes in response to a long‐term droughtNARA Subscribed
Climatic changes have profound effects on the distribution of biodiversity, but untangling the links between climatic change and ecosystem functioning is challenging, particularly in high diversity systems such as tropical forests. Tropical forests may also show different responses to a changing climate, with baseline climatic conditions potentially inducing differences in the strength and timing of responses to droughts. Trai...
