Plant Species and Functional Diversity along Altitudinal Gradients, Southwest Ethiopian Highlands
… central focus of ecologists and biogeographers. Altitudinal patterns of richness gradients are one of such striking patterns in the landscape. Despite its historical and ecological importance as a heuristic natural experimental site for development of ecological theories, the emergent patterns …

Climate control on plant performance across an Andean altitudinal gradient
… most pressing challenges of biology. The use of altitudinal gradients as 'natural experiments' to test the influence of climate on species distributions and performance has a long history in ecology and biogeography. This approach is a powerful way to gain insight into how species and ecosystems …

ECOLOGY OF GROUND-DWELLING CARABID BEETLES (COLEOPTERA: CARABIDAE) IN THE PERUVIAN ANDES
… zones along both disturbed and undisturbed gradients.

Soil respiration, microbial respiration and mineralisation in soils of montane rainforests of Southern Ecuador: influence of altitude
… soil organic carbon stocks. Furthermore, along altitudinal gradients, changes in stand structure and net primary production can be observed that have not been fully explained yet. As causes reduced microbial activity and nitrogen turnover in soils of tropical montane forests have been suggested. …

Bee diversity in Angola and community change along an altitudinal gradient at Serra da Chela (Bruco)
… of climate variation on species richness along altitudinal gradients. Climate variables and weather conditions are of extreme importance for insects particularly since their capacity of body temperature regulation is determined by the ambient temperature. Additionally, bee diversity has proven …

Fire Ecology of Northern Andean grasslands: Estimating recent fire history and its impact on páramo plants
… to account for varying growth of plants along altitudinal gradients and within different microclimates. Espeletia population structure and environmental conditions did vary with different fire intensities, but the patterns were not clear enough to predict post-fire intensity at a fine scale. …

Fine-Scale Mechanisms Influencing Germination Success, Seedling Growth and Survival in an Alpine Forest-Tundra Ecotone
Despite the expectation that treeline will advance as climate continues to warm, it has only done so in approximately half of all sites studied. One of the explanations for the nonresponse of treelines is based on reproductive limitations including seed production, germination, establishment and …
