Estimation and rapid identification of later stages during embryonic development of the oviparous lizard Sceloporus aeneus (Squamata: Phrynosomatidae)

open access: yesThe Anatomical Record, EarlyView.
Abstract Stages of embryonic development for reptiles have been presented in tables that may include all or part of embryonic development. When oviposition occurs in some lizards, embryos are already in the later stages of development; likewise, the size of the eggs increases as incubation time progresses.

Ontogeny of murine bony semicircular canal form

open access: yesThe Anatomical Record, EarlyView.
Abstract The labyrinthine geometry and functional anatomy of the semicircular canals have intrigued scientists for decades, and there has been considerable interest in understanding how these complex structures grow and develop with evidence emerging from human studies that size maturation occurs exceptionally early by comparison with other systems ...

From armadillos to sloths: Patterns and variations in xenarthran coronary anatomy

open access: yesThe Anatomical Record, EarlyView.
Abstract Species of the superorder Xenarthra play a vital ecological role in the Neotropics. Despite their evolutionary significance, anatomical studies on their coronary circulation remain scarce. This study investigated the coronary anatomy of 82 hearts from nine Xenarthra species across the Dasypodidae, Myrmecophagidae, and Bradypodidae.

Patterns of interspecific variation in labial microarchitecture among anthropoid primates and the evolution of the hominin lips

open access: yesThe Anatomical Record, EarlyView.
Comparative histological and semi‐automated image analysis of primate lips: Masson's trichrome‐stained sagittal sections were segmented to quantify the connective tissue, adipose, and muscular components, enabling interspecific comparisons of labial architecture.

Endothermy, neuron counts, and other issues: Further remarks on neurocognitive evolution in fossil vertebrates

open access: yesThe Anatomical Record, EarlyView.
Abstract Last year, we challenged the view that large‐bodied theropod dinosaurs such as Tyrannosaurus rex resembled primates in cognition and behavior, a proposition made by Herculano‐Houzel in 2023. More recently, Jensen et al. have criticized our work on this topic, raising methodological and conceptual issues.

Selenomethionine Regulates the Arachidonic Acid Metabolism‐Ferroptosis‐Inflammation Axis to Ameliorate Colitis

open access: yesAnimal Research and One Health, EarlyView.
Selenomethionine can ameliorate arachidonic acid‐induced colonic injury through synergistic mechanisms, including alleviating inflammatory responses, improving barrier integrity, enhancing antioxidant capacity by upregulating selenoprotein expression, selectively regulating AA metabolism to reduce pro‐inflammatory oxylipins and promote the production ...

ISOLATION AND MOLECULAR CHARACTERIZATION OF Leptospira borgpetersenii SEROVAR BALLUM

open access: yesTropical and Subtropical Agroecosystems, 2013
Rodents are the main reservoirs of pathogenic leptospires, spreading the organism to the environment and so the major risk factor for both, animals and humans to acquire leptospirosis.

Individualised niches: an integrative conceptual framework across behaviour, ecology, and evolution

open access: yesBiological Reviews, EarlyView.
ABSTRACT Individuals differ. While seemingly trivial, this insight has nevertheless led to paradigm shifts, as three key fields of organismal biology have seen marked changes in key concepts over the past few decades. In animal behaviour, it has become increasingly recognised that behavioural differences among individuals can be stable over time and ...
