Structure on lower montane secondary forests and shrublands in northern Antioquia, Colombia

open access: yesColombia Forestal, 2012
Tropical montane forests have the highest biodiversity in the world. However, they are being seriously threatened by deforestation, degradation and climate change. Their conservation is also at risk because we know little about their ecology.

Predicting the future of species assemblages under climate and land use land cover changes in Himalaya: A geospatial modelling approach

open access: yesClimate Change Ecology, 2022
Community ecology is driven by the patterns and drivers of species assemblages. Montane communities, in particular, are extremely vulnerable to climate change and are one of the first ecosystems to experience climate-induced biological responses. Loss of

The response of spider (Araneae) assemblages to structural heterogeneity and prey abundance in sub-montane vegetation modified by conservation grazing

open access: yesGlobal Ecology and Conservation, 2015
The effect of experimental livestock grazing regimens (4 treatments×6 replicates) on spiders via habitat structure and prey abundance was investigated on sub-montane habitats in the Southern Highlands of Scotland. The study, 2002–2004 included a baseline
