Mechanisms driving variation in American marten winter rest site use across the Western Great Lakes RegionNARA Subscribed
At high latitudes, the thermal protection of snowpack is important for many small-bodied mammal species during the winter. As depth and persistence of snow changes due to climate change, species that rely on snowpack’s insulation must increasingly depend on alternative thermal refuges. For the American marten ( Martes americana ), winter rest sites are predominantly in ground microsites. In some regions, however, martens prima...
SNAPSHOT USA 2024: Year 6 of the Coordinated National Camera Trap Survey of the United StatesNARA Subscribed
Motivation SNAPSHOT USA is an annual, multi‐contributor camera trap survey of mammals across the United States. The growing SNAPSHOT USA dataset is intended for tracking the spatial and temporal responses of mammal populations to changes in land use, land cover and climate. These data will be useful for exploring the drivers of spatial and temporal changes in relative abundance and distribution, as well as the impacts of speci...
To better understand and address global human–environment crises, interdisciplinary collaborations across the natural and social sciences have become increasingly common in conservation. Within such collaborations, the question of scale can cause tensions: how to agree on the unit of measurement and analysis? We contend there is value in scrutinizing the relationship between interdisciplinarity and scale more closely. Drawing...
Substrate availability and not thermal acclimation controls microbial temperature sensitivity response to long‐term warmingNARA Subscribed
Microbes are responsible for cycling carbon (C) through soils, and predicted changes in soil C stocks under climate change are highly sensitive to shifts in the mechanisms assumed to control the microbial physiological response to warming. Two mechanisms have been suggested to explain the long‐term warming impact on microbial physiology: microbial thermal acclimation and changes in the quantity and quality of substrates availa...
Early reduction of SARS-CoV-2-replication in bronchial epithelium by kinin B2 receptor antagonismNARA Subscribed
SARS-CoV-2 has evolved to enter the host via the ACE2 receptor which is part of the kinin-kallikrein pathway. This complex pathway is only poorly understood in context of immune regulation but critical to control infection. This study examines SARS-CoV-2-infection and epithelial mechanisms of the kinin-kallikrein-system at the kinin B 2 receptor level in SARS-CoV-2-infection that is of direct translational relevance. From acut...
Climate Change Modulates Multitrophic Interactions Between Maize, A Root Herbivore, and Its EnemiesNARA Subscribed
How climate change will modify belowground tritrophic interactions is poorly understood, despite their importance for agricultural productivity. Here, we manipulated the three major abiotic factors associated with climate change (atmospheric CO 2 , temperature, and soil moisture) and investigated their individual and joint effects on the interaction between maize, the banded cucumber beetle ( Diabrotica balteata ), and the ent...
Alternative futures for global biological invasionsNARA Subscribed
Scenario analysis has emerged as a key tool to analyze complex and uncertain future socio-ecological developments. However, currently existing global scenarios (narratives of how the world may develop) have neglected biological invasions, a major threat to biodiversity and the economy. Here, we use a novel participatory process to develop a diverse set of global biological invasion scenarios spanning a wide range of plausible...
Climate change decreases the cooling effect from postfire albedo in boreal North AmericaNARA Subscribed
Fire is a primary disturbance in boreal forests and generates both positive and negative climate forcings. The influence of fire on surface albedo is a predominantly negative forcing in boreal forests, and one of the strongest overall, due to increased snow exposure in the winter and spring months. Albedo forcings are spatially and temporally heterogeneous and depend on a variety of factors related to soils, topography, climat...
Impact of Seasonal and Temperature-Dependent Variation in Root Defense Metabolites on Herbivore Preference in Taraxacum officinaleNARA Subscribed
Plants experience seasonal fluctuations in abiotic and biotic factors such as herbivore attack rates. If and how root defense expression co-varies with seasonal fluctuations in abiotic factors and root herbivore attack rates is not well understood. Here, we evaluated seasonal changes in defensive root latex chemistry of Taraxacum officinale plants in the field and correlated the changes with seasonal fluctuations in abiotic fa...
