Functional Anatomy of the Pharynx of Glycera tridactyla Schmarda, 1861 (Annelida: Glyceriformia: Glyceridae). [PDF]
J MorpholMicro‐CT technology was used to investigate the functional anatomy of the pharynx in the polychaete Glycera tridactyla. The study revealed a complex system of pharyngeal muscles, including ring muscles, retensor muscles, intestinal retractor muscles, and longitudinal muscles of the buccal tube and oesophagus.

Seasonal Dynamics of the Gut Microbiome in Urban Feral Pigeons Are Associated With Environmental Conditions, Not With Diet Shifts. [PDF]
Ecol EvolUsing feral pigeons in urban environments, we show that microbiome diversity and composition vary seasonally despite stable diet composition. ABSTRACT Gut microbiomes play a crucial role in host physiology and seasonal adaptation. While seasonal shifts in avian gut microbiota are often attributed to seasonal diet variation, environmental factors may be

Lethaia, EarlyView., 2021 Biomineralization is a generic term used to indicate biological‐mediated mineral formation. In carbonate mineralization, nucleation of crystals can be: (1) controlled directly by the organisms, like in the skeletal formation of most metazoans; (2) induced by microbial communities, by indirect precipitation mediated by their metabolic activities; or (3)

Anais da Academia Brasileira de Ciências, 2022 Maldanids are tube-building polychaetes, known as bamboo-worms; inhabit diverse marine regions throughout the world. The subfamily Euclymeninae was proposed to include forms with anal and cephalic plates, a funnel-shaped pygidium, and a terminal anus ...
