Assessing habitat suitability for black grouse broods at the bioregional scale

open access: yesWildlife 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.

Dusky grouse seasonal resource selection in the Great Basin isolated mountain ranges of Nevada, USA

open access: yesWildlife Biology, EarlyView.
Dusky grouse Dendragapus obscurus are a montane forest grouse species with a paucity of information regarding their temporal and spatial resource use during critical times of high mortality and reproductive output. This lack of vital data may leave dusky grouse at risk of sub‐optimal management in many areas of their distribution, especially in the ...

Soil Phosphorus Fraction Characteristics in Different Alpine Grassland Types of the Qinghai–Tibet Plateau

open access: yesAgronomy
The alpine grassland ecosystem of the Tibetan Plateau is a vital base for animal husbandry and a key ecological security barrier in China. Phosphorus (P), an essential nutrient, is among the primary factors limiting grassland productivity.

Assessing physiological, behavioral and movement responses to Suprelorin implant delivery methods in free‐ranging eastern grey kangaroos Macropus giganteus

open access: yesWildlife Biology, EarlyView.
Overabundant populations of eastern grey kangaroos Macropus giganteus in peri‐urban areas pose ecological and social challenges. Current management strategies are often hindered by animal welfare and logistical concerns. This study aimed to assess stress responses of kangaroos to two contraceptive delivery methods.

Ecology of reintroduced Rocky Mountain bighorn sheep in Dinosaur National Monument La Ecología de Borrego Cimarron de las Montañas Rocosas Reintroducido en el Monumento Nacional de Dinosaurio

open access: yesWildlife Monographs, EarlyView.
We synthesized GPS telemetry, genetic, and pathogen data to evaluate metapopulation processes in a reintroduced Rocky Mountain bighorn sheep (Ovis canadensis canadensis) population in Dinosaur National Monument. We estimated subpopulation‐specific abundances and found 4 small subpopulations with high genetic diversity, partial connectivity, and ...

Soil N:P ratio influences species coexistence via nitrogen‐form niche differentiation in alpine grasslands

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Plant species coexistence in nutrient‐limited ecosystems is often maintained by niche differentiation in nitrogen (N) uptake. However, how this partitioning responds to changes in nutrient stoichiometry is still poorly understood.

Treeless vegetation of the Australian Alps

open access: yes, 2013
Based on 1222 floristic quadrat samples, 56 plant communities were identified in treeless vegetation in the Australian Alps of south-eastern Australia. (c. 35º 30´–38ºS, 146°–149°E). The study encompassed vegetation from above the upper limit of trees on

Shrub encroachment influences root traits and mycorrhization in subalpine grasslands

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Shrub encroachment into grasslands modifies ecosystem functions, species composition and soil properties. However, knowledge about its detailed below‐ground effects and specifically on concurrent changes in root traits and mycorrhizal associations is missing. We studied
