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...

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...

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...

Morphological disparity and structural performance of the dromaeosaurid skull informs ecology and evolutionary history
Non-avialan theropod dinosaurs had diverse ecologies and varied skull morphologies. Previous studies of theropod cranial morphology mostly focused on...

Evolutionary History and host Ecology Determine Acanthocephalan Egg Shape
Egg morphology varies among and within groups of parasites. Morphological variation is tightly coupled with transmission, and prior work suggests...

Host diversity, phylogenetic relationships and local environmental factors drive infection patterns of a non-native parasite in tropical floodplain fish assemblages
Biodiversity, biological traits of potential host species, and environmental conditions may mediate the emergence of new diseases. We assessed the...

How Aestivation Evolved in Turtles: A Macroevolutionary and Morphological Approach
Aestivation (summer dormancy) is a long-term multiday torpor in response to hot and dry periods. It has been detected in many species of terrestrial...

Ecomorphology of toothed whales (Cetacea, Odontoceti) as revealed by 3D skull geometry
Extant odontocetes (toothed whales) exhibit differences in body size and brain mass, biosonar mode, feeding strategies, and diving and habitat...

Genomic insights into body size evolution in Carnivora support Peto’s paradox
BackgroundThe range of body sizes in Carnivora is unparalleled in any other mammalian order—the heaviest species is 130,000 times heavier than the...

Derived faunivores are the forerunners of major synapsid radiations
Evolutionary radiations generate most of Earth’s biodiversity, but are there common ecomorphological traits among the progenitors of radiations? In...
