Assessing habitat suitability for black grouse broods at the bioregional scale
Wildlife Biology, EarlyView.The black grouse Lyrurus tetrix, a galliform species emblematic of the European Alps, is currently threatened by habitat change, particularly given the closure of heathland linked to the rising tree line at higher altitudes. The presence of heathlands in good ecological condition is, however, imperative for the species' reproduction.

Wildlife Letters, EarlyView.Climate change drives shifts in suitable habitats for Eurasian lynx and its prey (hare, roe deer) in Mohe, Daxing'anling Mountains. Under RCP scenarios, moderate warming (RCP4.5) promotes substantial habitat expansion, while high‐emission conditions (RCP8.5) lead to strong expansion in the 2050s but slower gains and partial contraction by the 2070s ...

Winter severity for white‐tailed deer in Alberta, Canada
Wildlife Society Bulletin, EarlyView.Abstract Winter Severity Indices (WSIs) are especially important for white‐tailed deer (Odocoileus virginianus), a species for which population dynamics often are tied to winter conditions throughout much of their range. However, existing WSIs often oversimplify environmental variability, limiting their ability to support effective management decisions.

Riding out the storm: Behavioural responses of a large herbivore to high‐Arctic winds
Journal of Animal Ecology, EarlyView.Using 11 years of GPS data from 61 muskoxen in Northeast Greenland, we show how increasing wind speed and Arctic storms reshape movement modes and habitat selection. Muskoxen respond by bedding in dense vegetation, prioritizing energy conservation over foraging, revealing a simple behavioural strategy with potential fitness consequences under ...

Variations and Correlation between NDVI and Meteorologic Factors in the Pearl River Basin
, 2010 对于一个特定的区域特定的时间段来说影响植被覆盖变化的主要因素是气候因素，主要包括降水、温度和光照。珠江流域地形复杂，东西狭长，气象因子差异较大，地表植被覆盖较好，研究珠江流域植被覆盖变化与气象因子之间的关系具有重要意义。 本文利用1982-1999年月平均NDVI和气象因子资料，分析了珠江流域植被和气象因子的时空分布特征，采用奇异值分解（SVD）方法和联合EOF方法研究了珠江流域NDVI和降水在年和年际尺度上的异常关系，利用相关系数 ...

Elephant space use and habitat selection change across drought timescales
Journal of Animal Ecology, EarlyView.Drought threatens wildlife worldwide, but little is known about wildlife behaviour during drought. This study combines 19 years of elephant GPS data with drought conditions at three timescales. Key findings include that elephants (i) move less during drought at a 1‐month timescale and (ii) change habitat selection across drought timescales.
