Tracing the evolutionary history of the morpho‐anatomy of baculum in primates

open access: yesThe Anatomical Record, EarlyView.
Abstract Animal morphology reflects both evolutionary history and present‐day adaptation. Male mammal copulatory structures such as the baculum (penile bone) are ideal for studying these processes because of their complexity and high interspecific variability. In primates, however, research has focused mostly on baculum length.

Home and away: allometry and climate drive morphology of European rabbits in their native and introduced range

open access: yesOikos, EarlyView.
Climatic conditions shape phenotypic evolution by driving adaptations that optimise organismal function. Invasive species provide valuable systems to study these processes, as they often encounter novel climatic conditions in their introduced ranges. The European rabbit Oryctolagus cuniculus, native to the Iberian Peninsula, has established populations

Host Phylogeny and Feeding Habit Jointly Govern Mammalian Gut Microbiota Composition

open access: yesIntegrative Zoology, EarlyView.
Herbivores showed higher alpha diversity than carnivores/omnivores, while omnivores had the highest beta diversity. Host phylogeny influenced gut microbiota more strongly in herbivores/omnivores, with phylogenetic distance correlating to microbiota dissimilarity.

Phylogenetic and Functional Originality Shape Species Positions in Flea–Mammal Networks Across Biogeographic Realms

open access: yesIntegrative Zoology, EarlyView.
The relationship between the position of a flea species in the networks and its functional originality was found to be consistently positive in all realms, independently of which originality index was used. ABSTRACT We investigated the relationships between a species’ network position (measured as the combined normalized degree, species strength, and ...

Female‐Biased Sexual Size Dimorphism and Its Potential Causes in Hairy‐Winged Bats

open access: yesIntegrative Zoology, EarlyView.
Based on the integration of molecular genetics, traditional and geometric morphology, and acoustic characteristics of hairy‐winged bats (a species that was historically misclassified into two species due to extreme craniodental divergence between the sexes) in multiple regions of China, we quantified the sexual size dimorphism (SSD) between males and ...

Simple Method for Establishing Primary Leporidae Skin Fibroblast Cultures

open access: yesCells, 2021
Commercial hare and rabbit immortalized cell lines are extremely limited regarding the many species within the lagomorpha order. To overcome this limitation, researchers and technicians must establish primary cell cultures derived from biopsies or ...

Environmental Drivers of Geographic Isolation in Three Pika Species in Northeast Asia

open access: yesIntegrative Zoology, EarlyView.
Using bias‐corrected species distribution models, we found that geographic isolation among three northeastern Asian pika species (Ochotona coreana, Ochotona mantchurica, and Ochotona hyperborea) reflects both divergent environmental preferences and potential competitive interactions. O.

Evolutionary history of lagomorphs in response to global environmental change. [PDF]

open access: yesPLoS ONE, 2013
Although species within Lagomorpha are derived from a common ancestor, the distribution range and body size of its two extant groups, ochotonids and leporids, are quite differentiated.
