Osteological correlates of the respiratory and vascular systems in the neural canals of Mesozoic ornithurines Ichthyornis and Janavis

open access: yesThe Anatomical Record, EarlyView.
Abstract In birds, the neural canal houses a variety of anatomical structures including the spinal cord, meninges, spinal vasculature, and respiratory diverticula. Among these, paramedullary diverticula and the extradural dorsal spinal vein may leave behind osteological correlates in the form of pneumatic foramina and fossae, and a bilobed geometry of ...

Skeletal pathologies in extant crocodilians as a window into the paleopathology of fossil archosaurs

open access: yesThe Anatomical Record, EarlyView.
Abstract Crocodilians, together with birds, are the only extant relatives to many extinct archosaur groups, making them highly important for interpreting paleopathological conditions in a phylogenetic disease bracketing model. Despite this, comprehensive data on osteopathologies in crocodilians remain scarce.

Heat Stress and Gut Microbiome Dynamics in Poultry: Interplay, Consequences, and Mitigation Strategies

open access: yesAnimal Research and One Health, EarlyView.
Heat stress disrupts gut microbial balance in poultry, impairing nutrient absorption and immunity. This review outlines the interplay between thermal stress and microbiome dynamics and discusses integrative mitigation strategies, probiotics, phytogenics, cooling systems, and genetic adaptation to enhance poultry resilience.

Digital Spatial Technologies to Compose the Map of the Southeast Iberia Megalithic Phenomenon. The Case Study of Fonelas (Granada, Spain)

open access: yesArchaeological Prospection, EarlyView.
ABSTRACT Megalithic landscapes in Southeast Iberia remain unevenly and insufficiently documented, particularly in rugged areas where traditional survey methods are limited. This paper addresses this gap by applying a multiscalar approach to the megalithic necropolises of the Fardes River (Granada, Spain), with the objective of detecting, documenting ...
