Chinese Pangolin Changes Local Vertebrate Assemblages and Contributes to Their Interspecific Interactions by Burrowing and Revisitation

Integrative Zoology, EarlyView.
In this study, we systematically analyzed the utilization patterns of Chinese pangolin burrows by sympatric species in Guangdong Province, China, including differences in species composition using burrow mounds and burrow tunnels. We found that repeated visits to burrows by Chinese pangolin promoted the use of burrows by sympatric species, suggesting ...

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.

Museomics Deciphers the Phylogeographic Differentiation and Conservation Status of a Montane Pheasant

Integrative Zoology, EarlyView.
Museum specimens provide a rich source of historical DNA, enabling insights into phylogenetic relationships and demographic history of the endangered Koklass Pheasant. Our findings uncovered a previously unrecognized population in Guizhou province and highlighted elevated extinction risk in populations from Anhui province and Southern China, informing ...

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 ...
