Reproductive success under constraints: Does increased maternal activity during lactation offset poor habitat and individual quality in an income breeder?

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Human‐induced environmental modifications may alter forage access and, hence, how animals manage energy trade‐offs during critical periods. Reproduction, especially lactation, is the most energetically costly process for female mammals.

Plant functional diversity of alpine grasslands in the central and eastern Qinghai-Tibet Plateau

Research in Cold and Arid Regions
Alpine grasslands are fragile ecosystems that are characterized by low species richness, where plant diversity plays a crucial role in maintaining the functioning, stability, and sustainability of the ecosystem.

Soil Fauna Affects Dissolved Carbon and Nitrogen in Foliar Litter in Alpine Forest and Alpine Meadow

PLOS ONE, 2015
Dissolved organic carbon (DOC) and total dissolved nitrogen (TDN) are generally considered important active biogeochemical pools of total carbon and nitrogen. Many studies have documented the contributions of soil fauna to litter decomposition, but the effects of the soil fauna on labile substances (i.e., DOC and TDN) in litter during early ...

Fungal Batrachochytrium dendrobatidis infections proliferate during amphibian terrestrial dormancy

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract The spread and impact of wildlife pathogens is often seasonal, and identifying the season(s) of highest impact can be critical to biodiversity and public health management.

Productive Overcompensation of Alpine Meadows in Response to Yak Grazing in the Eastern Qinghai-Tibet Plateau

Frontiers in Plant Science, 2019
Understanding the interaction between large herbivores and pasture production, especially with respect to the grazing optimization hypothesis, is critical for pasture management and generating theoretical and testable predictions.

Community assembly on inland cliffs is context‐dependent

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Under harsh environmental conditions, community assembly processes are expected to drive pronounced functional convergence, with communities dominated by stress‐tolerant species.

Elements on the move: How ungulate migration expands Alpine biogeochemical footprints

Journal of Animal Ecology, EarlyView.
Using a spatially explicit model parameterized with GPS telemetry, we show that migratory and resident red deer play distinct roles in nitrogen redistribution across alpine landscapes. Migrants uniquely transport nitrogen upslope and up elevation, linking ecosystem element pools and revealing how the loss of migration alters large‐scale ecosystem ...

Climatic conditions, landscape, and habitat quality drive patch occupancy and larval density of a threatened mire butterfly

Insect Science, EarlyView.
The Moorland Clouded Yellow (Colias palaeno) benefited from cattle grazing in three different ways by (i) fostering the nectar supply; (ii) enhancing rejuvenation of the host plant (Vaccinium uliginosum); and (iii) improving microclimatic conditions for successful development of the immature stages.

Geological Substrate Is Related to Tooth Senescence and Population Dynamic: The Case Study of Alpine Chamois (Rupicapra rupicapra L.)

Integrative Zoology, EarlyView.
In Alpine chamois, the complete wear of the first molar coincides with the beginning of senescence and the progress of tooth wear on calcareous substrate is slower than the one on other substrates, increasing life expectancy. Thus, the first molar wear may actually be considered as an effective descriptor of senescence stage.
