Geological Substrate Is Related to Tooth Senescence and Population Dynamic: The Case Study of Alpine Chamois (Rupicapra rupicapra L.)

Integrative Zoology, EarlyView.
In Alpine chamois, the complete wear of the first molar coincides with the beginning of senescence and the progress of tooth wear on calcareous substrate is slower than the one on other substrates, increasing life expectancy. Thus, the first molar wear may actually be considered as an effective descriptor of senescence stage.

Small Object Detection Method for Bioimages Based on Improved YOLOv8n Model

Integrative Zoology, EarlyView.
This study proposes a small object detection method for bioimages based on an improved YOLOv8n model. Experimental results demonstrate that the proposed approach effectively enhances detection precision, recall, and mAP50, offering a novel solution for the technical challenges in biological microscopy research.

Effects of Vector Density on Blood Parasite Spread and Health Consequences for Avian Hosts: An Experimental Epidemiology Blueprint

Integrative Zoology, EarlyView.
In an experimental epidemiology setup, groups of pigeons were exposed to different numbers of infective malaria vectors. Vector number explained the speed of transmission, the final prevalence, and changes in host behavior. ABSTRACT Vector density plays a critical role in the transmission dynamics of vector‐borne diseases and thus in their health and ...

Volatile Compounds in Feathers of the Scarlet Macaw (Ara macao) Reflect Sex and Pair‐Bond Status

Integrative Zoology, EarlyView.
Scarlet macaws exhibit sex‐ and pair‐related differences in plumage volatile composition, with males showing greater chemical richness. Partnered individuals differ in specific compound classes, whereas no clear association with immune function was detected. These results support a potential role for olfactory cues in sexual and social communication in

Scene gist categorization by pigeons [PDF]

, 2014
Scene gist categorization in humans is rapid, accurate, and tuned to the fundamental statistical regularities in the visual world. However, no studies have investigated whether scene gist categorization is a general process shared across species, or ...
