Lack of thermal acclimation in multiple indices of climate vulnerability in bumblebees.

Indices of climate vulnerability are used to predict species' vulnerability to climate change based on intrinsic physiological traits, such as thermal tolerance, thermal sensitivity and thermal acclimation, but rarely is the consistency among indices evaluated simultaneously. We compared the thermal physiology of queen bumblebees between a species experiencing local declines () and a species exhibiting continent-wide increases (). We conducted a multi-week acclimation experiment under simulated climate warming to measure critical thermal maximum (CT), critical thermal minimum (CT), the thermal sensitivity of metabolic rate and water loss rate and acclimation in each of these traits.

Coastal deoxygenation impacts phytoplankton communities crucial for marine productivity. The inter- and intra-annual variability in phytoplankton communities at a shallow (27 m) station over the Western Indian Shelf (CaTS site, off Goa) during deoxygenation events of the late southwest monsoon (LSWM September-October) were studied from 2020 to 2023. The water column (0-27 m depth) experienced seasonal hypoxia/anoxia at subsurface depths (0-1.

Department of Soil, Water, and Climate, University of Minnesota, Saint Paul, MN, USA. Electronic address:
Ash byproducts have been used as soil amendments to recycle nutrients and modify soil properties such as pH or density. Interest in these practices has continued with increasing emphasis on sustainability, particularly regarding phosphorus reuse from incinerated sewage sludge. Given recent advancements in microbial analyses, the impacts of these practices can now be studied from the soil microbiome perspective.

Department of Ecology and Environmental Protection, University of Rzeszów, Poland.
Mountain environments, as biodiversity hotspots, are subject to numerous anthropological pressures. In mountain areas, a common threat to stream biocenoses is the timber industry. Timber industry increases the fine sediment input into the mountain rivers; furthermore, timber transport requires the construction of low-water crossings across streams.

Department of Biological Sciences, University of Illinois at Chicago, Chicago, IL 60607, USA.
Changes in winter precipitation accompanying emerging climate trends lead to a major carbon-climate feedback from Arctic tundra. However, the mechanisms driving the direction, magnitude, and form (CO and CH) of C fluxes and derived climate forcing (i.e.
