International Aquatic Research, 2018 Communities of benthic invertebrates from a series of intermittent headwater streams spanning over a short elevation gradient (i.e., ~ 180–500 m) were investigated in April–July 2010 and May–July 2011.

A continuous/discontinuous Galerkin formulation for a strain gradient-dependent damage model [PDF]
, 2004 The numerical solution of strain gradient-dependent continuum problems has been hindered by continuity demands on the basis functions. The presence of terms in constitutive models that involve gradients of the strain field means that the $C^0$ continuity

ISPRS International Journal of Geo-Information, 2021 The Three-River Source Region (TRSR) is vital to the ecological security of China. However, the impact of global warming on the dynamics of vegetation along the elevation gradient in the TRSR remains unclear.

Comparison of female and male behavior in the elevated gradient of aversion [PDF]
Brazilian Journal of Medical and Biological Research, 2022 The elevated gradient of aversion (EGA) is an apparatus for investigating the exploratory behavior of rats in 3-min sessions, consisting of three different sections of the same size: tunnel, closed arm, and open arm. Factorial analyses have defined three factors: exploration, impulsivity, and self-protection.

Ecological and evolutionary drivers of the elevational gradient of diversity [PDF]
Ecology Letters, 2018 AbstractEcological, evolutionary, spatial and neutral theories make distinct predictions and provide distinct explanations for the mechanisms that control the relationship between diversity and the environment. Here, we test predictions of the elevational diversity gradient focusing on Iberian bumblebees, grasshoppers and birds.

Geomorphic controls on elevational gradients of species richness [PDF]
Proceedings of the National Academy of Sciences, 2016 Significance How biodiversity changes with elevation has long attracted the interest of researchers because it provides key clues to how biota respond to geophysical drivers. Experimental evidence reveals that biodiversity often peaks at intermediate elevations, and yet a clear explanation is still elusive.

Evolutionary dynamics of the elevational diversity gradient in passerine birds [PDF]
Nature Ecology & Evolution, 2021 Low-elevation regions harbour the majority of the world's species diversity compared to high-elevation areas. This global gradient suggests that lowland species have had more time to diversify, or that net diversification rates have been higher in the lowlands.

Shifts in community composition and co-occurrence patterns of phyllosphere fungi inhabiting Mussaenda shikokiana along an elevation gradient [PDF]
PeerJ, 2018 The altitudinal effects on the distributions of phyllosphere fungal assemblages in conspecific plants remain poorly elucidated. To address this, phyllosphere fungal communities associated with Mussaenda shikokiana were investigated at four sites across a
