Marine sponges are able to process a variety of carbon (C), nitrogen (N), phosphorous (P),
and silicon (Si) dissolved compounds, in addition to the particulate C, N, and P obtained …

Silica deposition is a fundamental process in sponges. Most sponges in the Classes
Demospongiae and Hexactinellida secrete siliceous elements, which can subsequently …

Les éponges sécrètent une variété de squelettes minéraux de calcite, d'aragonite et (ou) de
silice amorphe qui les renforcent et les protègent des perturbations physiques. La …

Being sessile filter feeders, sponges may be disadvantaged by sediments in many ways, eg
through clogging and burial. However, in order to correctly recognize negative effects of …

Sponges (Porifera) belong to an ancient metazoan lineage that represents one of the
earliest branches of the animal tree. The superficial region of the sponge body is devoid of …

Most sponges produce skeletons formed by spicules, structural elements that develop in a
wide variety of sizes and tridimensional shapes. The morphologies of spicules are often …

Um dos motivos pelos quais sempre considerei um privilégio dirigir uma instituição com as
características do Museu Nacional é a diversidade de temas que esta instituição abriga …

Siliceous sponges, one of the few animal groups involved in a biosilicification process,
deposit hydrated silica in discrete skeletal elements called spicules. A multidisciplinary …

Sponges (Porifera) are recognized as aquatic multicellular organisms which developed an
effective biochemical pathway over millions of years of evolution to produce both biologically …

Marine bioerosion is projected to increase under future environmental conditions, and
interest in investigating the ecological roles of bioeroding sponges has grown substantially …
