Comparative histological, histochemical, and histometric evaluation of the esophagus in two avian species with different feeding habits (Ciconia ciconia and Buteo buteo)

open access: yesThe Anatomical Record, EarlyView.
Histological structure of esophagus. Abstract The aim of this study was to conduct a comparative evaluation of the histological and histochemical organization of the esophagus in two avian species with different feeding ecologies. A total of 6 individuals were used for this purpose (3 storks, 3 common buzzards).

Diet and Oviposition Deprivation Effects on Survivorship, Gonotrophic Dissociation, and Mortality of Anopheles gambiae s.s.

open access: yesJournal of Parasitology Research, 2022
Diet quality is of paramount importance for egg batch size, longevity, and mortality of vector mosquitoes. Oviposition site presence and absence assumed to be dry season means a lot to the survivorship and mortality of most anthropophilic malaria vectors

Evaluating Bergmann's and Allen's rules in the long bones of the eastern gray squirrel

open access: yesThe Anatomical Record, EarlyView.
Abstract Ecogeographical rules predict variation in body size and appendage proportions across climatic gradients, yet intraspecific tests using long bones from wild populations remain limited among small mammals. This study tests the hypothesis that eastern gray squirrels (Sciurus carolinensis) conform to Bergmann's rule, that is, body size increases ...

The “costly son” hypothesis: Sons exacerbate obstetrical dilemmas in humans and other mammals

open access: yesThe Anatomical Record, EarlyView.
Abstract Human childbirth has often been considered uniquely difficult among mammals, yet recent evidence suggests that obstructed labor and fetopelvic disproportion are widespread across placental mammals. Here, we propose the “costly son” hypothesis: because male offspring are typically larger at birth, they impose greater obstetric risk on mothers ...

Body mass and sex estimation from lower carnassial tooth morphometry in the endangered Iberian wolf (Canis lupus signatus): An ecomorphological analysis of sexual size dimorphism

open access: yesThe Anatomical Record, EarlyView.
Abstract The Iberian wolf (Canis lupus signatus) is an endangered subspecies characterized by highly fragmented populations and increasing human–carnivore conflict across the Iberian Peninsula. Although body mass strongly influences predator–prey dynamics and ecological performance, quantitative assessments of sexual size dimorphism (SSD) and body mass

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 ...

Labor conditions in wildlife fieldwork and implications for scientific integrity and safety

open access: yesThe Bulletin of the Ecological Society of America, EarlyView.
Abstract Wildlife fieldwork underpins ecological and sustainable science, yet the labor conditions of those who conduct it remain uneven. Wildlife technicians routinely operate under hazardous conditions while working on short‐term contracts with limited job security, restricted decision‐making power, and insufficient structural protections.
