Experimentos a alta presión y alta temperatura: Ventanas al universo

Física de la Tierra, 1970
A partir de los indicios sobre la composicion terrestre que proporcionan los metodos indirectos, como la propagacion de ondas sismicas, es posible recrear en el laboratorio condiciones de presion y temperatura similares a las del interior de la Tierra y de otros planetas, y estudiar como afectan estas condiciones a un metal o mineral determinado.

Surviving in a Warming and Fragmented World: Long‐Term Population Dynamics of the Lizard Gonatodes humeralis

Austral Ecology, Volume 50, Issue 10, October 2025.
ABSTRACT Climate change presents significant challenges to species survival; however, the long‐term effects on tropical lizard populations remain poorly understood. Previous studies have predicted contrasting outcomes, with some forecasting a high risk of extinction due to rising temperatures, while others suggest greater resilience in tropical ...

Urban developmental environments alter tadpole phenotypes depending on origin

Journal of Animal Ecology, Volume 94, Issue 9, Page 1707-1719, September 2025.
Urbanisation has rapidly altered the ecological and evolutionary contexts for many species. Using a reciprocal transplant experiment with frog larvae, we find that urban environments can alter morphological, developmental and behavioural traits at both ecological and evolutionary scales.

Using aerial thermography to map terrestrial thermal environments in unprecedented detail

Methods in Ecology and Evolution, Volume 16, Issue 8, Page 1688-1702, August 2025.
Abstract The accurate quantification of thermal environments is crucial for predicting the impacts of climate change across ecosystems. Two major obstacles exist in mapping biologically relevant thermal landscapes: (1) overcoming the mismatch between the scale at which environmental data are typically collected and the scale at which a particular ...

Habitat dynamics of flagship species for conservation prioritization in southern Europe

Conservation Biology, Volume 39, Issue 4, August 2025.
Abstract Biodiversity loss is accelerating due to human actions, and decision‐making for conservation needs to be streamlined. Ex situ biodiversity modeling and monitoring based on satellite time‐series data could be an affordable and cost‐efficient tool for improving the prioritization of conservation areas.

Thermal tolerance is linked to anatomical but not morphological leaf traits in woody species of Andean tropical montane forests

Functional Ecology, Volume 39, Issue 6, Page 1537-1549, June 2025.
Read the free Plain Language Summary for this article on the Journal blog. Abstract The world is experiencing a rise in global temperatures as a result of climate change. Higher temperatures along with more frequent heat waves negatively impact physiological levels and ultimately lead to plant death.
