Life-History Responses to the Altitudinal Gradient [PDF]
, 2017 We review life-history variation along elevation in animals and plants and illustrate its drivers, mechanisms and constraints. Elevation shapes life histories into suites of correlated traits that are often remarkably convergent among organisms facing the same environmental challenges.

Lauraceae Along an Altitudinal Gradient in Southern Brazil [PDF]
Floresta e Ambiente, 2019 ABSTRACT We performed a phytosociological study on an altitudinal gradient in Lauráceas State Park (Parque Estadual das Lauráceas/PR), aiming to describe the Montane Atlantic Rain Forest, to verify the importance of Lauraceae, and to evaluate the communities’ successional stage.

Altitudinal Gradient of Evapotranspiration in Tropical Highlands
, 2022 Tropical highlands supply water for large cities in the Andes. Based on meteorological records from three weather stations in the paramo Chingaza, Colombia evapotranspiration (ET) is estimated based on the Penman-Monteith (P-M) approach to compare the altitudinal variation and assess the radiation and aerodynamic effects on the water losses.

Diversity of springtails (Hexapoda) according to a altitudinal gradient [PDF]
Pesquisa Agropecuária Brasileira, 2009 The objective of this work was to elevate gradient effect on diversity of Collembola, in a temperate forest on the northeast slope of Iztaccíhuatl Volcano, Mexico. Four expeditions were organized from November 2003 to August 2004, at four altitudes (2,753, 3,015, 3,250 and 3,687 m a.s.l.). In each site, air temperature, CO2 concentration, humidity, and

Ephemeroptera Along Altitudinal Gradients: a Scientometric Review
Anais da Academia Brasileira de CiênciasAbstract Altitude is a key environmental factor influencing ecological patterns and biodiversity in ecosystems. In aquatic organisms, taxonomic richness typically declines with increasing altitude, although studies on Ephemeroptera show variability in this trend.

Artropofauna epigea del páramo Estambul (Tolima), Colombia
Biota Colombiana, 2016 Los páramos almacenan y capturan gas carbónico atmosférico y son clave en el equilibrio del ciclo hídrico y regulación del clima regional. Dada su relevancia, en el 2013 se evaluó la fauna epigea del páramo Estambul (Tolima, Colombia), entre 3100 m a ...

Diversification and coexistence amid widespread and persistent gene flow in Andean trees
New Phytologist, EarlyView.Andean Prunus species diversify into and occupy distinct elevation zones, remaining morphologically distinct. Yet, ancient introgression and recent admixture cross both phylogenetic and ecological distances. This suggests these species function as a long‐lived syngameon rather than fully isolated lineages, which may help explain how tree diversity ...

Methane-cycling microorganisms in soils of a high-alpine altitudinal gradient [PDF]
FEMS Microbiology Ecology, 2016 Methanogens and methanotrophs play unique roles as producers and consumers of the greenhouse gas methane (CH4) in soils, respectively. Here, we aimed to reveal whether and to which extent methane-cyclers occur in high-alpine soils, and to assess their spatial distribution along an altitudinal gradient (2700-3500 m) in the Austrian Alps at sites located

Functional responses in a lizard along a 3.5‐km altitudinal gradient
Journal of Biogeography, 2023 AbstractAimPhysiological and metabolic performance are key mediators of the functional response of species to environmental change. Few environments offer such a multifaceted array of stressors as high‐altitude habitats, which differ markedly in temperature, water availability, UV radiation and oxygen pressure compared to low‐altitude habitats. Species

Trait‐based plant ecology: some history and some future
New Phytologist, EarlyView.Schematic of plant species range boundaries, some mechanisms that might set them, and some traits that might explain them. Summary Since around the year 2000, trait‐based ecology has become self‐aware as a strand of research within ecology. How did this happen? What is trait‐based ecology now? And where might it go in future?
