A Case Report on Rehabilitation of the Asiatic Black Bear (Ursus thibetanus ussuricus) in the Wild 亚洲黑熊 (Ursus thibetanus ussuricus) 野外放归野化案例报告

open access: yesWildlife Letters, EarlyView.
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.

Identifying Causes of Reproductive Failure in Zoo‐Housed Bush Dogs (Speothos venaticus) to Improve Ex Situ Management

open access: yesZoo Biology, EarlyView.
We distributed a survey to global institutions housing bush dogs (Speothos venaticus) to collect data on factors which may affect litter survival. Information from the Zoological Information Management System (ZIMS) and studbook records supplemented this dataset. We found that within northern temperate regions, the number of pups reared to the age of 1

Half-Heard Voices of the Primal Zone; Sleep and Waking in a Poem by Cao Shuying

open access: yes, 2017
Initially touching artifacts and sculpture from ancient Greece, and the risk of misreading thought or emotion cross-culturally, this essay draws briefly on Wordsworth’s testimony that poetic process arises first in a primally sensual and pre-verbal zone.

Social network dynamics under experimental manipulations of predation risk and food abundance in wild rock hyraxes

open access: yesJournal of Animal Ecology, EarlyView.
This study combines replicated experimental manipulation, social network analysis, network permutations and meta‐analysis to disentangle active from spatially‐induced changes in animal network structure in the wild. It reveals that short‐term environmental changes primarily alter space use, with limited effects on social structure.

No Evidence for Seasonal Variations in Fatigue, Sleepiness, and Insomnia Symptoms: Spring Fatigue is a Cultural Phenomenon rather than a Seasonal Syndrome

open access: yesJournal of Sleep Research, EarlyView.
ABSTRACT Although not as prominent as in other animals, humans also experience seasonal variations in sleep duration and circadian processes. These variations are likely primarily driven by changes in photoperiod length. Anecdotally, many people report experiencing fatigue and low energy levels, particularly during spring in Germany, Switzerland and ...

Torpor‐assisted migration: Regular use of shallow torpor reduces rest‐phase energy expenditure for songbirds during migration

open access: yesJournal of Animal Ecology, EarlyView.
Migrating songbirds regularly use shallow torpor (up to 98% of birds for some species) to save energy (up to 42%) during inactive periods. This Ruby‐crowned Kinglet Corthylio calendula that was captured after a spring snowstorm highlights the value of being able to save energy when encountering unfavourable conditions.
