Avian phylogenetic and functional diversity are better conserved by land‐sparing than land‐sharing farming in lowland tropical forests

open access: yesJournal of Applied Ecology, Volume 61, Issue 10, Page 2497-2509, October 2024.
To minimise the loss of avian phylogenetic diversity and functional traits from farming in the Amazon, it is imperative to protect large blocks of undisturbed and regenerating forests. The intensification required within existing farmlands to make space for spared lands while meeting agricultural demand needs to be sustainable, avoiding long‐term ...

La vegetación briofítica rupícola en relación con los gradientes altitudinal e hígrico en el Montseny (Barcelona) [PDF]

open access: yes, 1986
Bryophytic vegetation along an elevation gradient of 1350 m in Montseny has been studied by sampling 36 stones or walls with different moisture index, calculated from the distance to the nearest running water.

Physiological thermal niches, elevational ranges and thermal stress in dendrobatid frogs: An integrated approach

open access: yesJournal of Biogeography, Volume 51, Issue 10, Page 1880-1893, October 2024.
Abstract Aim We investigated the relationship between thermal physiology, elevational distribution and thermal stress among nine closely related dendrobatid frogs during their aquatic stage by employing an integrated approach, combining thermal physiology, environmental temperature modelling and predictive assessments of current and future exposure to ...

Effects of increasing soil moisture on Antarctic desert microbial ecosystems

open access: yesConservation Biology, Volume 38, Issue 4, August 2024.
Abstract Overgeneralization and a lack of baseline data for microorganisms in high‐latitude environments have restricted the understanding of the microbial response to climate change, which is needed to establish Antarctic conservation frameworks. To bridge this gap, we examined over 17,000 sequence variants of bacteria and microeukarya across the ...

Vegetation Dynamics along the Altitudinal Gradient

open access: yes
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.
