Phylogenetic analyses of complete mitochondrial genome sequences suggest a basal divergence of the enigmatic rodent Anomalurus

open access: yesBMC Evolutionary Biology, 2007
Background Phylogenetic relationships between Lagomorpha, Rodentia and Primates and their allies (Euarchontoglires) have long been debated. While it is now generally agreed that Rodentia constitutes a monophyletic sister-group of Lagomorpha and that this

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.

Demographic buffering in natural populations: A multi‐level perspective

open access: yesJournal of Animal Ecology, EarlyView.
We introduce a multi‐level framework that unites stochastic elasticities with nonlinear selection to test demographic buffering. Applying it across mammals reveals a key insight: ecological robustness to variability often decouples from evolutionary constraint, reshaping how we understand resilience under environmental stochasticity.

Urogenital myiasis caused by Lucilia sericata (Diptera: Calliphoridae) in a domestic rabbit in Italy

open access: yesVeterinaria Italiana, 2020
The report describes a case of urogenital myiasis in a domestic rabbit Oryctolagus cuniculus L. (Lagomorpha: Leporidae) caused by Lucilia sericata (Meigen; Diptera: Calliphoridae) in region Emilia-Romagna (Northern Italy).

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.

Estudio del cráneo mediante morfometría geométrica en dos especies de Sylvilagus Gray, 1867 (Mammalia: Lagomorpha) [PDF]

open access: yes, 2019
Within the genus Sylvilagus Gray, 1867, Sylvilagus brasiliensis (Linnaeus, 1758) and Sylvilagus floridanus (J.A. Allen, 1890) are some of its recognized species, for whom morphological studies in both species are extensive. Therefore, a comparative study

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 ...

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 ...

An intriguing shift occurs in the novel protein phosphatase 1 binding partner, TCTEX1D4: evidence of positive selection in a pika model [PDF]

open access: yes, 2017
T-complex testis expressed protein 1 domain containing 4 (TCTEX1D4) contains the canonical phosphoprotein phosphatase 1 (PPP1) binding motif, composed by the amino acid sequence RVSF.

Historical shifts, geographic biases, and biological constraints shape mammal species discovery

open access: yesJournal of Systematics and Evolution, EarlyView.
Taxonomic descriptions of mammals have become more robust from 1990 to 2025, with increased specimen sampling, broader comparisons, and more integrative methods. However, disparities remain: tropical and small‐bodied species are less comprehensively described, reflecting ongoing geographic and biological biases.
