Computational fluid dynamics simulations of airflow through the nasal passages of rhinolophoid bats

open access: yesThe Anatomical Record, EarlyView.
Abstract The nasal passages of bats that emit their echolocation call through their nostrils have adapted for sound emission as well as standard respiratory and olfactory functions. Rhinolophids, hipposiderids and rhinonycterids all use a high duty cycle (HDC) echolocation strategy.

Historical birth records from 1896 to 1944 from the Basel maternity hospital, Switzerland, reveal significant obstetric selection pressures

open access: yesThe Anatomical Record, EarlyView.
Abstract Maternal and neonatal morbidity and mortality have declined dramatically during the last century. Historical data are therefore important sources to study the evolutionary selection pressures related to childbirth and how they have fluctuated over time.

Variable grouping patterns in primates: A test of the better competitor hypothesis in male Verreaux's sifaka (Propithecus verreauxi)

open access: yesThe Anatomical Record, EarlyView.
Abstract Intraspecific variation in social organization (IVSO) within primate populations can arise due to male mating competition. Verreaux's sifaka (Propithecus verreauxi) populations exhibit both single‐male and multi‐male groups, providing an opportunity to examine the relationship between male competitive ability and social organization.

Ursolic Acid Alleviates Orchitis via Modulating Ferroptosis in Peritubular Myoid Cells of Testis

open access: yesAnimal Research and One Health, EarlyView.
Ursolic acid modulates key ferroptosis‐related pathways in the peritubular myoid cells of the testis in forest musk deer. ABSTRACT Chronic stress adversely affects reproductive health, increasing susceptibility to pathologies such as orchitis. Additionally, the maintenance of iron homeostasis is essential for preserving the function of the testicles ...
