Salinity causes widespread restriction of methane emissions from small inland waters

Nature Communications
Inland waters are one of the largest natural sources of methane (CH4), a potent greenhouse gas, but emissions models and estimates were developed for solute-poor ecosystems and may not apply to salt-rich inland waters.

Evaluation of thyroglobulin autoantibodies in dogs at the time of diagnosis of hypoadrenocorticism and during treatment

Veterinary Record, EarlyView.
Abstract Background Autoimmune thyroiditis (AIT) may occur more frequently in dogs with hypoadrenocorticism (HA) than previously recognised. The objective of this study was to determine the presence of thyroglobulin autoantibodies (TgAAs) in dogs with HA.

Spraying drones: efficacy of integrating an avian repellent with drone hazing to elicit blackbird flock dispersal and abandonment of sunflower fields

Wildlife Biology, EarlyView.
Multiple management strategies exist to combat bird damage to agriculture. We explored combining two tools, drones as frightening devices and an avian repellent, to assess effectiveness of an integrated method to deter large flocks on complex landscapes. We evaluated the ability of a spraying drone (DJI Agras MG‐1P) deploying Avian Control (i.e. active

Dusky grouse seasonal resource selection in the Great Basin isolated mountain ranges of Nevada, USA

Wildlife Biology, EarlyView.
Dusky grouse Dendragapus obscurus are a montane forest grouse species with a paucity of information regarding their temporal and spatial resource use during critical times of high mortality and reproductive output. This lack of vital data may leave dusky grouse at risk of sub‐optimal management in many areas of their distribution, especially in the ...

New perspectives on temperate inland wetlands as natural climate solutions under different CO2-equivalent metrics

npj Climate and Atmospheric Science
There is debate about the use of wetlands as natural climate solutions due to their ability to act as a “double-edged sword” with respect to climate impacts by both sequestering CO2 while emitting CH4.
