Bryophyte diversity patterns in flooded and tierra firme forests in the Araracuara Region, Colombian Amazonia [PDF]

, 2004
We investigated patterns of bryophyte species richness and composition in two forest types of Colombian Amazonia, non-flooded tierra firme forest and floodplain forest of the Caquetá River.

Evaluation of Phenological Cycles and Thermal Time of Apple Crop Growing at Different Altitudinal Gradients in North Western Himalayas

International Journal of Economic Plants, 2019
A field study was conducted in 2015 and 2016 to evaluate the phenological cycles and thermal time of apple crop of economic importance growing at different climate represented by varied altitudinal gradients in Himachal Pradesh, India.

Ecotype differentiation in the face of gene flow within the diving beetle Agabus bipustulatus (Linnaeus, 1767) in northern Scandinavia.

PLoS ONE, 2012
The repeated occurrence of habitat-specific polyphyletic evolved ecotypes throughout the ranges of widely distributed species implies that multiple, independent and parallel selection events have taken place.

Determinants of species richness patterns in the Netherlands across multiple taxonomic groups [PDF]

, 2009
We examined the species richness patterns of five different species groups (mosses, reptiles and amphibians, grasshoppers and crickets, dragonflies, and hoverflies) in the Netherlands (41,500 km2) using sampling units of 5 × 5 km. We compared the spatial

Vegetation Dynamics along the Altitudinal Gradient

In mountainous or hilly terrain, the term “altitudinal gradient” describes a change in environmental parameters such as temperature, precipitation, and soil properties with increasing altitude. This gradient has a significant impact on vegetation dynamics and its association.

Physical and land-cover variables influence ant functional groups and species diversity along elevational gradients [PDF]

, 2013
Of particular importance in shaping species assemblages is the spatial heterogeneity of the environment. The aim of our study was to investigate the influence of spatial heterogeneity and environmental complexity on the distribution of ant functional ...

Biodiversity is a cauliflower under the sunlight [PDF]

, 2012
For a long time ecologists have questioned the variations of biodiversity across the latitudinal gradient. Recently it has emerged that the changes in [beta]-diversity are caused simply by changes in the sizes of species pools.

The Relative Influences of Climate and Competition on Tree Growth along Montane Ecotones in the Rocky Mountains

, 2016
Distribution shifts of tree species are likely to be highly dependent upon population performance at distribution edges. Understanding the drivers of aspects of performance, such as growth, at distribution edges is thus crucial to accurately predicting ...
