We collected Amur tiger track data and occurrence data through snow track tracking, sample line surveys, and camera traps. The study concluded that forest roads, scrub vegetation, and human landscape factors were the main factors influencing Amur tiger movements at fine scales and examined the negative correlation between tiger path curvature values ...

Survey optimization for invasive Burmese pythons informed by camera traps 基于自动相机监测技术的入侵物种缅甸蟒的调查优化
We evaluated the utility of camera traps to survey invasive Burmese pythons in the Florida Keys by deploying cameras pointed towards target areas of known radiotagged snakes under two trigger mechanisms—motion‐triggered or timelapse. We estimated detection probability and diel activity to optimize future surveys using timelapse camera traps and paired ...

Trends and progress in studying butterfly migration 蝴蝶迁徙行为的研究趋势与进展
We show (i) the potential importance of non‐English‐language literature for understanding butterfly migration globally, (ii) studies are mostly concentrated in North America and Europe with very few from the tropics, (iii) most studies are focused on three species: the Monarch (Danaus plexippus), Painted Lady (Vanessa cardui) and Red Admiral (Vanessa ...

Unravelling the processes between phenotypic plasticity and population dynamics in migratory birds
This work highlights the critical role of the stopover stage of northward migration in the influence of migration tactics and population dynamics of migratory birds across the whole annual cycle. The authors also demonstrate the key processes linking individual migration tactics and population dynamics.

This paper presents evidence relating to a forecast‐based cash and non‐food item distribution among vulnerable herder households during the 2017–18 dzud (extreme winter) season in Mongolia, and analyses the results of a quasi‐experimental study evaluating its impacts. An innovative approach in disaster risk reduction, forecast‐based financing (FbF) can

Asiatic black bears in Russia face conservation threats such as habitat destruction and fragmentation, which exacerbate food shortages caused by crop failures. This study explores an innovative approach to rehabilitating bears that abandon hibernation in mid‐winter due to extreme exhaustion by providing supplemental food near their den sites.

Tracking with GPS and accelerometers shows that great evening bats in subtropical China use two overwintering strategies: some remain in continuous hibernation, while others switch between torpor and activity as temperatures change. This behavioral flexibility, shaped by climate, underscores the importance of protecting diverse roosting habitats for ...
