What Goes First? Effects of Starvation on the Body Condition of a Neotropical Dung Beetle

Entomologia Experimentalis et Applicata, Volume 174, Issue 4, Page 321-328, April 2026.
We investigated how prolonged starvation affects key physiological traits in the dung beetle Dichotomius bos. Prolonged starvation leads to significant reductions in body dry mass and fat reserves, while muscle mass remains unchanged. These findings indicate that dung beetles prioritize the maintenance of locomotor muscles while mobilizing stored ...

Hyperdominant Trees Reveal Savanna Vulnerability Under Climate Change

Global Change Biology, Volume 32, Issue 4, April 2026.
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.

Ecología-mundo, un nuevo paradigma para el estudio de las migraciones internacionales

EMPIRIA: Revista de Metodología de Ciencias Sociales, 2020
A lo largo del siglo XX y comienzos del XXI la comunidad académica ha desarrollado numerosas teorías para explicar el fenómeno de las migraciones internacionales, tal como Massey et al. (1998) recogieron en su famoso libro “Worlds in motion”. Sin embargo,

Mixture models unveil the origin of the enigmatic Satyrinae butterfly genera Calisto and Llorenteana (Lepidoptera, Nymphalidae, Satyrinae) Los modelos de mezcla revelan el origen de los enigmáticos géneros de mariposas Satyrinae Calisto y Llorenteana (Lepidoptera, Nymphalidae, Satyrinae)

Systematic Entomology, Volume 51, Issue 2, April‐June 2026.
We provide the first reliable hypothesis on the phylogenetic position of Calisto and Llorenteana within the tribe Satyrini, based on genomic data representing all subtribes. We apply for the first time nucleotide mixture models, which overcame the inconsistencies resulting from the use of partitioned models in this and previous studies, obtaining a ...

Importance and spatial patterns of invisible fisheries in Amazonian clear‐water rivers as revealed by fisher knowledge and collaboration

Conservation Biology, Volume 40, Issue 1, February 2026.
The graphical abstract highlights the research collaboration with fishers through interviews to record fishers' knowledge and participatory monitoring, to provide data on small‐scale fisheries in three clear water rivers (Trombetas, Tapajos and Tocantins).

Plant conservation in a changing Mediterranean world

PLANTS, PEOPLE, PLANET, Volume 8, Issue 1, Page 49-72, January 2026.
The Mediterranean is one of five climatic regions on the planet characterised by a prolonged summer drought, exceptional plant diversity and high rates of endemism. We provide a framework to link the ecology of plant species conservation in the context of rapid and extreme climate deregulation to a philosophical typology of temporal attitudes (i.e ...

A Novel Sampling Protocol for Fruit‐Feeding Butterflies in Grasslands and Open Habitats

Austral Ecology, Volume 51, Issue 1, January 2026.
This study proposed a novel sampling protocol for fruit‐feeding butterflies in grasslands and open areas in the subtropical region. The new method involves the use of Van Someren‐Rydon bait traps placed on specific supports closer to the ground, aiming to capture the true diversity of butterflies in these habitats.
