Predicting the distributions of under-recorded Odonata using species distribution models [PDF]

, 2012
1. Absences in distributional data may result either from the true absence of a species or from a false absence due to lack of recording effort. I use general linear models (GLMs) and species distribution models (SDMs) to investigate this problem in ...

Physiological Variation in Jarillo Peach Across Altitudinal Gradients

Agronomy
Environmental factors affect plant physiological processes. Understanding these factors can increase productivity, especially in tropical mountain ecosystems, where they vary with altitude. This study aimed to analyze the physiological variations related

Tropical rainforest bird community structure in relation to altitude, tree species composition, and null models in the Western Ghats, India

, 2005
Studies of species distributions on elevational gradients are essential to understand principles of community organisation as well as to conserve species in montane regions.

Manual of tropical bryology [PDF]

, 2003
Bryophytes belong to the oldest land plants. They existed already in the Palaeozoic 300 mio years ago in forms which were hardly different from the extant species. They remained relatively unchanged with relatively low evolution rates (and are thus often

Carbon sequestration and elevational gradient: The case of Yegof mountain natural vegetation in North East, Ethiopia, implications for sustainable management

Cogent Food & Agriculture, 2020
Environmental gradients (altitude) are the factors that determine the carbon capturing the potential of a given forest. This study was conducted to determine the influence of elevation in the Yegof mountain forest’s carbon sequestration potential.

Natural variation in abiotic stress responsive gene expression and local adaptation to climate in Arabidopsis thaliana. [PDF]

, 2014
Gene expression varies widely in natural populations, yet the proximate and ultimate causes of this variation are poorly known. Understanding how variation in gene expression affects abiotic stress tolerance, fitness, and adaptation is central to the ...

Altitudinal distribution of birds in a mountainous region in southeastern Brazil

Zoologia (Curitiba), 2010
We studied the altitudinal distribution of 426 bird species in the Serra dos Órgãos, a mountainous region in southeastern Brazil. Thirty-four localities were visited between 1991 and 2009.

From lowlands to highlands: how elevation and habitat complexity drive anuran multidimensional diversity? [PDF]

PeerJ
Background Montane environments in Neotropical regions are known for their rich diversity of amphibians, but the ecological drivers behind this diversity along altitudinal gradients remain poorly understood. We investigated the effects of the altitudinal
