A technique for optimal temperature estimation for modeling sunrise/sunset thermal snap disturbance torque [PDF]

open access: yes
A predictive temperature estimation technique which can be used to drive a model of the Sunrise/Sunset thermal 'snap' disturbance torque experienced by low Earth orbiting spacecraft is described.

The Impacts of the COVID‐19 Pandemic and Urbanization Vary Among Coyotes, Red Foxes, and Gray Foxes Across the Contiguous United States 新冠疫情和城市化对美国大陆的郊狼、赤狐和灰狐的影响变化

open access: yesWildlife Letters, EarlyView.
How did COVID‐19 reshape wild canid behavior across urban and rural landscapes? We calculated the kernel density estimates of diel activity for three canid species (coyote, gray fox, and red fox) using independent detections from standardized camera traps across the USA.

Can edge AI mitigate environmental effects on camera trap performance?

open access: yesWildlife Society Bulletin, EarlyView.
A camera trap enabled with edge artificial intelligence (AI) mitigated the effects of increased air temperature on the probability of false positive detections, but at the cost of an increased probability of missed detections. Other environmental variables affected camera trap performance differently, suggesting the need to account for camera trap ...

Greater prairie‐chicken nest survival and changes in vegetation structure and composition with conservation grazing

open access: yesWildlife Society Bulletin, EarlyView.
We studied how conservation grazing influenced vegetation composition and structure and greater prairie‐chicken nest survival in northwestern Minnesota. We observed effects of grazing on vegetation in the year of grazing, but these changes dissipated by August of the post‐grazing year.

Vision at high latitudes: High sensitivity without specific boreal adaptations in photoreception in reindeer (Rangifer tarandus L.)

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract The light climate at high latitudes, in particular the extended twilight of winter and the reduced diel variation in light level in midsummer and midwinter, potentially constrains visual function and the synchronisation of temporal organisation in polar species. In this

Fine‐scale spatial risk models to predict avian collisions with power lines

open access: yesJournal of Applied Ecology, EarlyView.
Our study illustrates a framework for using bird movement data to provide insights into avian behaviour and the risk they encounter around power line infrastructure. Electricity delivery industries can use these models to identify the electrical infrastructure that poses the highest risk to avian survival and prioritise mitigation efforts, thereby ...
