Fit for purpose? Analysis of the relationship between skull, beak shape and feeding ecology in Psittaciformes

Journal of Anatomy, EarlyView.
Psittaciformes exhibit high levels of morphological diversity, particularly in skull and beak structure, previously linked to diet and body size. Although there were some levels of significance between diet and beak shape, body mass was a much stronger co‐variate. Diet is not determining beak shape within the clade.

The raphe nuclear organization and serotonergic system in the bat (Artibeus planirostris)

Journal of Anatomy, EarlyView.
Schematic representation of the methodological workflow used to characterize the serotonergic (5‐HT) system in the bat Artibeus planirostris. Serotonin (5‐HT) immunohistochemistry was performed on brainstem sections to identify and map the distribution of serotonergic neurons within the raphe nuclei.

The Keystone‐Pathogen Hypothesis Updated: The Role of Porphyromonas gingivalis in Periodontitis

Journal of Periodontal Research, EarlyView.
Porphyromonas gingivalis orchestrates a coordinated manipulation of immune and inflammatory responses in periodontal tissues which leads to the generation of a dysbiotic, subgingival biofilm community, and progression of periodontitis. The type 9 secretion system, lipid A modification, and the formation of outer membrane vesicles are important ...

Limited contribution by non‐volant small mammals to regeneration in ironstone rocky outcrops

Restoration Ecology, EarlyView.
Abstract Introduction Animal‐mediated seed dispersal contributes substantially to natural regeneration in degraded areas. However, the role of seed dispersal by non‐volant small mammals (NVSM), mainly marsupials and rodents, in contributing to regeneration remains underexplored, especially in mountaintop, open‐canopy ecosystems.

Detection of antibodies against Leptospira spp in free-living marsupials caught in the Eastern Amazon

Revista da Sociedade Brasileira de Medicina Tropical
INTRODUCTION: Serological surveys are important to assess the health status of wild animals. In this study, antibodies against Leptospira spp, causal agents of leptospirosis, were detected in free-living marsupials in the State of Pará, Brazil. METHODS:
