Pigeons in the sun: Thermal constraints of eumelanic plumage in the rock pigeon (Columba livia).
Journal of Thermal Biology, 2020 In wild vertebrates, several species exhibit eumelanic color polymorphism with the coexistence of dark and light morphs. The maintenance of such polymorphism suggests the existence of a selective balance between the morphs and a large body of literature ...

CTX-M-producing Escherichia coli Isolated from urban pigeons (Columba livia domestica) in Brazil.
Journal of Infection in Developing Countries, 2019 INTRODUCTION Worldwide urban pigeons (Columba livia domestica) are an important reservoir of pathogenic and multidrug-resistant bacteria (MDR). Plasmids are key genetic elements in the dissemination of antimicrobial drug resistance in bacteria, including

Injuries in deep time: interpreting competitive behaviours in extinct reptiles via palaeopathology
Biological Reviews, EarlyView.ABSTRACT For over a century, palaeopathology has been used as a tool for understanding evolution, disease in past communities and populations, and to interpret behaviour of extinct taxa. Physical traumas in particular have frequently been the justification for interpretations about aggressive and even competitive behaviours in extinct taxa.

Ontogeny of foraging behaviour in an opportunistic gull inhabiting urban marine ecosystems
Wildlife Biology, EarlyView.Urbanization affects ecosystems by reducing biodiversity and displacing species from native habitats. While some suffer, others, like urban wildlife, adapt through innovative feeding and behaviours that improve their fitness in human‐altered settings. Despite research on wildlife in urban areas, the development of foraging behaviour in urban species is

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.
