Direct and indirect effects of cougar predation on bighorn sheep fitness

Ecology, Volume 105, Issue 9, September 2024.
Abstract Predation has direct effects on prey population dynamics through mortality, and it can induce indirect effects through fear. The indirect effects of predation have been documented experimentally, but few studies have quantified them in nature so that their role in prey population dynamics remains controversial.

Transmission ecosystems of Echinococcus multilocularis in China and Central Asia [PDF]

, 2017
From continental to regional scales, the zoonosis alveolar echinococcosis (AE) (caused by Echinococcus multilocularis) forms discrete patches of endemicity within which transmission hotspots of much larger prevalence may occur.

Herbivorous mammals adjust their feeding patterns according to the abundance of available diet to adapt to the effects of grassland degradation

Global Ecology and Conservation
The degradation of grasslands on the Qinghai–Tibet Plateau has severely impacted the region’s ecology and productivity, subsequently affecting the dietary niche of the region’s herbivores.

Evolutionary analysis of mitochondrially encoded proteins of toad-headed lizards, Phrynocephalus, along an altitudinal gradient. [PDF]

, 2018
BACKGROUND: Animals living at high altitude must adapt to environments with hypoxia and low temperatures, but relatively little is known about underlying genetic changes.

Effect of bioturbation by plateau pika (Ochotona curzoniae) on soil carbon and nitrogen stocks in alpine meadows

Global Ecology and Conservation
The plateau pika (Ochotona curzoniae) is a predominant small burrowing herbivore that plays a vital role within the alpine meadow ecosystem of the Qinghai-Tibet Plateau.
