Hair Microstructure Diversity in Neotropical Marsupials: Roles of Phylogenetic Signal and Adaptation
Guard hair microstructure in Neotropical marsupials has been described in two different patterns: medullar and cuticular. The main objective of this...

Metabolic rate and ecological traits of ectoparasites: a case study with seven flea species from the Negev Desert
We studied the relationship between fleas’ metabolic rate and their ecological traits, using data on standard metabolic rate (SMR), mean abundance,...

Understanding flammability and bark thickness in the genus Pinus using a phylogenetic approach
Pinus species dominate fire-prone ecosystems throughout the northern hemisphere. Their litter drive fires that control plant community flammability...

Hair Microstructure Diversity in Neotropical Marsupials: Roles of Phylogenetic Signal and Adaptation
Guard hair microstructure in Neotropical marsupials has been described in two different patterns: medullar and cuticular. The main objective of this...

Phylogenetic comparative analysis of the cerebello-cerebral system in 34 species highlights primate-general expansion of cerebellar crura I-II
The reciprocal connections between the cerebellum and the cerebrum have been suggested to simultaneously play a role in brain size increase and to...

Ecological correlates of cranial evolution in the megaradiation of dipsadine snakes
BackgroundDipsadine snakes represent one of the most spectacular vertebrate radiations that have occurred in any continental setting, with over 800...

Geographic, climatic, and phylogenetic drivers of variation in colobine activity budgets
Folivorous primates are typically considered time minimizers because the constraints of their unique digestive systems require them to spend a large...

Ecological factors and parity mode correlate with genome size variation in squamate reptiles
BackgroundEvidence of correlation between genome size, the nuclear haploid DNA content of a cell, environmental factors and life-history traits have...

The evolutionary drivers of primate scleral coloration
The drivers of divergent scleral morphologies in primates are currently unclear, though white sclerae are often assumed to underlie human...

Morphological convergence and adaptation in cave and pelagic scale worms (Polynoidae, Annelida)
Across Annelida, accessing the water column drives morphological and lifestyle modifications—yet in the primarily “benthic” scale worms, the...

Do body size and habitat shape call frequencies of Brazilian hylids (Amphibia: Anura)?
Despite acoustic signals playing a fundamental role on animal behavior and reproduction, our understanding of the mechanisms driving their evolution...

Measures and models of visual acuity in epipelagic and mesopelagic teleosts and elasmobranchs
Eyes in low-light environments typically must balance sensitivity and spatial resolution. Vertebrate eyes with large "pixels" (e.g., retinal ganglion...

Quantitative analysis of body colouration in Sebastes rockfishes
Body colouration, a trait under strong selection, is influenced by the visual background of the environment. The stable influence of depth on visual...

Semicircular canal shape diversity among modern lepidosaurs: life habit, size, allometry
BackgroundThe shape of the semicircular canals of the inner ear of living squamate reptiles has been used to infer phylogenetic relationships, body...

Shark genome size evolution and its relationship with cellular, life-history, ecological, and diversity traits
Among vertebrates, sharks exhibit both large and heterogeneous genome sizes ranging from 2.86 to 17.05 pg. Aiming for a better understanding of the...

Languages with more speakers tend to be harder to (machine-)learn
Computational language models (LMs), most notably exemplified by the widespread success of OpenAI's ChatGPT chatbot, show impressive performance on a...

An evolutionary ecomorphological perspective on the assembly of a neotropical bat metacommunity
The evolution of the bat skull has been extensively studied at broad spatial scales. While ecomorphological partitioning of niches has been...

Biological traits as determinants in the macroecological patterns of distribution in loliginid squids
Macroecological studies have primarily focused on investigating the relationships between body size and geographic distribution on large scales,...

Using a Phylogenetic Framework to Assess the Role of Fruit Size in Food Selection by the Andean Night Monkey (Aotus lemurinus)
The study of diet and food selection is foundational to understanding how primates interact with their environment. Due to the potential evolutionary...
