Motivation Here, we make available a second version of the BioTIME database, which compiles records of abundance estimates for species in sample events of ecological assemblages through time. The updated version expands version 1.0 of the database by doubling the number of studies and includes substantial additional curation to the taxonomic accuracy of the records, as well as the metadata. Moreover, we now provide an R packag...
Broadening diversity, equity, accessibility, and inclusion in the process and development of climate assessmentsNARA Subscribed
Comprehensive assessments of scientific knowledge are essential to inform efforts to mitigate greenhouse gas emissions and adapt to climate change impacts. The Fifth National Climate Assessment (NCA5), released in late 2023, adopted clear diversity, equity, accessibility, and inclusion (DEAI) goals and trainings, which helped diversify expert participation, broaden the types of knowledge included, and widen public engagement....
Translating and embedding equity-thinking into climate adaptation: an analysis of US citiesNARA Subscribed
Cities increasingly recognize the importance of furthering social equity in their climate adaptation planning. Such efforts are often in response to grassroots mobilizations, yet it is not clear to what extent they translate into urban coalitions, policy designs, and implementation efforts within city governments. In this paper, we respond to this knowledge gap by assessing how equity-thinking is translated into cities’ adapta...
Identifying dominant environmental predictors of freshwater wetland methane fluxes across diurnal to seasonal time scalesNARA Subscribed
While wetlands are the largest natural source of methane (CH 4 ) to the atmosphere, they represent a large source of uncertainty in the global CH 4 budget due to the complex biogeochemical controls on CH 4 dynamics. Here we present, to our knowledge, the first multi‐site synthesis of how predictors of CH 4 fluxes (FCH4) in freshwater wetlands vary across wetland types at diel, multiday (synoptic), and seasonal time scales. We...
Impact of Water Mixing and Ice Formation on the Warming of Lake Superior: A Model‐guided Mechanism StudyNARA Subscribed
The Laurentian Great Lakes are one of the most prominent hotspots for the study of climate change induced lake warming. Warming trends in large, deep lakes, which are often inferred by the observations of lake surface temperature (LST) in most studies, are strongly linked to the total lake heat content. In this study, we use a 3D hydrodynamic model to examine the nonlinear processes of water mixing and ice formation that cause...
Ice Cover in the Great Lakes has significant impacts on regional weather, economy, lake ecology, and human safety. However, forecast guidance for the lakes is largely focused on the ice-free season and associated state variables (currents, water temperatures, etc.) A coupled lake-ice model is proposed with potential to provide valuable information to stakeholders and society at large about the current and near-future state of...
Anthropogenic nitrogen deposition predicts local grassland primary production worldwideNARA Subscribed
Humans dominate many important Earth system processes including the nitrogen (N) cycle. Atmospheric N deposition affects fundamental processes such as carbon cycling, climate regulation, and biodiversity, and could result in changes to fundamental Earth system processes such as primary production. Both modelling and experimentation have suggested a role for anthropogenically altered N deposition in increasing productivity, nev...
