Grazing and climate interact to regulate greening trends in Mediterranean grasslands

Journal of Applied Ecology, Volume 63, Issue 1, January 2026.
Our results show that traditional grazing systems can maintain grassland stability without causing degradation, but they can also increase the ecosystem's vulnerability to climate change. We provide clear evidence that GPS‐based livestock monitoring is a powerful and scalable tool for sustainable rangeland management.

Resource suitability drives low use of avian‐excavated tree cavities: A multi‐state occupancy dynamics approach

Journal of Animal Ecology, Volume 94, Issue 11, Page 2295-2307, November 2025.
Birds that nest in tree cavities are sometimes dependent on a few cavity‐excavating bird species to make nesting sites available. Such interdependency, however, does not always materialize because excavated cavities may be unsuitable for continued use, even when available for several years after excavation.

Inhibition of rhizobial cheaters by the host Medicago truncatula involves repression of symbiotic functions and induction of defense

New Phytologist, Volume 248, Issue 3, Page 1458-1474, November 2025.
Summary In symbiotic plant–microbe interactions, the host invests considerable amounts of resources in the microbial partner. If the microbe does not reciprocate with a comparable symbiotic benefit, it is regarded as a cheater. The host responds to cheaters with negative feedback mechanisms (sanctions) to prevent fitness deficits resulting from being ...

Escribir en comunidad: Construcción de relaciones y responsabilidad en la producción de conocimiento

American Anthropologist, Volume 127, Issue 3, Page 447-465, September 2025.
ABSTRACT As anthropology reckons with its past, present, and future, anthropologists increasingly seek to challenge inequities within the discipline and academia more broadly. Anthropology, regardless of subdiscipline, is a social endeavor. Yet research often remains an isolating (though not necessarily solitary) process, even within research teams and

Expression patterns of melanin‐related genes are linked to crypsis and conspicuousness in a pumpkin toadlet

Molecular Ecology, Volume 34, Issue 15, August 2025.
Abstract Colour signals play pivotal roles in different communication systems, and the evolution of these characters has been associated with behavioural ecology, integumentary production processes and perceptual mechanisms of the species involved. Here, we present the first insight into the molecular and histological basis of skin colour polymorphism ...

Policy &Internet, Volume 17, Issue 2, June 2025.
ABSTRACT Tools developed for the purpose of unilaterally exploiting computer systems and their communications will pose a persistent policy and regulatory problem. Regulation of hacking tools to date, however, has been piecemeal, inconsistent and often incoherent.
