Thermal ecology of montane Atelopus (Anura: Bufonidae): A study of intrageneric diversity

Journal of Thermal Biology, 2016
Harlequin frogs (Bufonidae: Atelopus) are among the most threatened frog genus in the world and reach very high elevations in the tropical Andes and the Sierra Nevada de Santa Marta (SNSM). Learning about their thermal ecology is essential to infer sensitivity to environmental changes, particularly climate warming. We report on the activity temperature

Combined community ecology and floristics, a synthetic study on the upper montane evergreen broad-leaved forests in Yunnan, southwestern China

Plant Diversity, 2016
The upper montane evergreen broad-leaved forest in Yunnan occurs mainly in the zone of persistent cloud and has a discontinuous, island-like, distribution. It is diverse, rich in endemic species, and likely to be sensitive to climate change.

Chimpanzee (Pan troglodytes ellioti) ecology in a Nigerian montane forest

, 2012
Due to high levels of exploitation, habitat loss and habitat degradation, Pan troglodytes has experienced such a significant population reduction over the past 20 to 30 years that it is now on the IUCN (International Union for the Conservation of Nature and Natural Resources) Red List of Endangered Species.

Role of topography, soil and climate on forest species composition and diversity in the West Usambara Montane Forests of Tanzania

Folia Oecologica, 2023
Understanding the variables that determine the variation in forest species composition and diversity in tropical montane systems remains a topic for discussion in plant ecology. This is especially true in areas where the topography is complex and forests

Unravelling spatial scale effects on elevational diversity gradients: insights from montane small mammals in Kenya

BMC Ecology and Evolution
Background Montane ecosystems play crucial roles as global biodiversity hotspots. However, climatic changes and anthropogenic pressure increasingly threaten the stability of montane community dynamics, such as diversity-elevation interactions, creating a

Stable functional structure despite high taxonomic variability across fungal communities in soils of old-growth montane forests

Microbiome, 2023
Background Major advances over the past decade in molecular ecology are providing access to soil fungal diversity in forest ecosystems worldwide, but the diverse functions and metabolic capabilities of this microbial community remain largely elusive.

American Bison Ecology and Bison-Cattle Interactions in an Isolated Montane Environment

, 2021
As bison are considered to be ecologically extinct, and negative interactions between bison and cattle are perceived to limit bison restoration and cattle production, I designed a series of studies to test for potential competition between bison (Bison bison) and cattle (Bos taurus) for forage on the Henry Mountains in southern Utah.

Seasonal variation in the behavioural ecology of samango monkeys (Cercopithecus albogularis schwarzi) in a southern latitude montane environment

Primates, 2021
Samango monkeys (Cercopithecus albogularis schwarzi) in the Soutpansberg Mountains, South Africa, experience a highly seasonal climate, with relatively cold, dry winters.

Genetics, Ecology, and Conservation of Montane Populations of Colorado Chipmunks (Tamias quadrivittatus) [PDF]

Journal of Mammalogy, 1996
Population genetics and ecological characteristics were assessed in relictual montane populations of the Colorado chipmunk ( Tamias quadrivittatus ). This study focused on conservation and systematic relationships of two endangered populations of T. quadrivittatus inhabiting the Oscura and Organ mountains of central and southern New Mexico, relative to
