Abstract. Island systems provide powerful natural laboratories for studying the processes that maintain species boundaries. The lacertid lizard Gallotia ga

Understanding how communication systems evolve across heterogeneous environments requires examining multiple signalling modalities. In 2017 and 2018, we examined geographic variation in chemical sign...

Aim Understanding how body size and geographic range size influence species abundance is central to macroecology. Here, we characterized these relationships for reef fishes, the world's most diverse...

Storch et al. [1] argue that equilibrium theory provides the most coherent framework for reconciling cradles, museums, and large-scale biodiversity patterns. Their Equilibrium Theory of Biodiversity D...

In this study, we assess the ecological and environmental factors associated with population decline in the world's anurans, taking into account their evolutionary relationships. A large majority of ....

Brachycephalus are miniaturized diurnal frogs inhabiting the leaf litter of the Brazilian Atlantic Forest, mainly in montane areas. The genus includes 42 currently recognized species, 35 of which bein...

Gallotia galloti scale traits are driven by climate and human pressures. High dorsal density correlates with hotter, dryer environments and larger scales with higher sun exposure, while ventral scale....

Mitonuclear discordance—evolutionary discrepancies between mitochondrial and nuclear DNA phylogenies—can arise from various factors, including introgression, incomplete lineage sorting, recent or anc...

We analyzed global anuran diversity across six ecotypes to understand how environmental factors shape distribution patterns. Terrestrial and arboreal species emerged as primary contributors to overal....

The study of environmental DNA (eDNA) is a powerful tool for detecting and monitoring aquatic species, but sample preservation methods can critically affect analytical outcomes. Here, we examined the ...

Despite their critical role in maintaining organismal health, the factors driving intraspecific variation in gut microbiotas in the wild are poorly understood. Gallotia galloti is a lizard endemic to ...

The study of environmental DNA (eDNA) is becoming an increasingly valuable tool for investigating and monitoring aquatic communities. However, significant gaps remain in understanding its dynamics and...

Heads of ant workers harbour the mouthparts and respective musculature, varying drastically in morphology. The mandible adductor muscles occupy most of the head's internal volume, and their contractio...

Abstract. There is considerable variation of sexual size dimorphism (SSD) in body mass among animal groups, yet the drivers of interspecific variation in S

My research integrates phylogenies, maps and functional traits to uncover the processes that generated the diversity of life.

We are looking for an NSF-funded post-doc in our lab in the Department of Integrative Biology at the University of Texas at Austin. The work will examine immune mechanisms that potentially underlie…

The invasive mollusc Limnoperna fortunei, commonly known as the golden mussel, poses significant threats to ecosystems and economic sectors, primarily hydroelectric power generation, due to the encrus...

The “win-stay, lose-switch” (WSLS) strategy used by birds involves decisions to maintain or alter the characteristics of the subsequent nest according to the...

Habitat fragmentation and climate change affect both pest and engineering species of termites that are widely distributed from the tropics to temperate regions. Our study mechanistically uncovered how...

This study investigates the impact of clade density (CD), a measure of potential interspecific competition, on the geographical range evolution of terrestrial vertebrates. By analysing distribution a....

Revision of the conservation status and assessment of the Green Status of the Parana Antwren Formicivora acutirostris with management proposals - Volume 34

Understanding the interplay between rarity and vulnerability in the decline and extinction of species is a major challenge for modern conservation bio…

Body size is a fundamental trait in evolutionary and ecological research, given that it varies allometrically with several relevant features, such as life-history and physiological traits. Although pr...
