Canalized to heat, plastic to cold: adaptive coordination of leaf and seed strategies in populations spanning an elevational gradient. [PDF]

New Phytol
Summary In tropical mountains, surviving temperature extremes demands finely tuned strategies. We investigated how populations of the bromeliad Pitcairnia flammea across a 2200 m elevational gradient balance genetic canalization and plasticity, and whether thermal strategies are coordinated between seeds and leaves.

Hyperdominant Trees Reveal Savanna Vulnerability Under Climate Change. [PDF]

Glob Chang Biol
The Brazilian Cerrado's forest structure relies disproportionately on just 30 hyperdominant tree species, which represent 50% of all individuals despite accounting for only 2% of species richness. This study evaluates their vulnerability under climate change scenarios for 2100.

Tropical Land-Use Change Disrupts Zeta-Diversity Across Taxa. [PDF]

Glob Chang Biol
We studied birds, dung beetles, and orchids across natural and human‐transformed habitats in the Colombian Andes to understand how land‐use change affects biodiversity. We found that deforestation simplifies ecological communities and reduces both rare and widespread species, especially orchids.

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.

Drivers of Collembola assemblages along an altitudinal gradient in northeast China [PDF]

Ecology and Evolution, 2022
AbstractAltitudinal changes in the diversity of plants and animals have been well documented; however, soil animals received little attention in this context and it is unclear whether their diversity follows general altitudinal distribution patterns. Changbai Mountain is one of few well‐conserved mountain regions comprising natural ecosystems on the ...

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.
