Post-Embryonic Development and Formation of the Heterocoelic Aquiferous System in Two Species of Calcareous Sponges (Calcarea, Porifera). [PDF]

Mol Reprod Dev
ABSTRACT We characterized the morphogenetic processes of larval metamorphosis and the development of the olynthus and heterocoelic aquiferous system (AS) in Sycettusa hastifera (syconoid) and Paraleucilla magna (leuconoid) (Porifera, Calcarea). Metamorphosis and development up to the olynthus were similar in both species.

Morphological Adaptations for Shell Anchoring in Calcinus tibicen: Insights From µCT Imaging, Histology and Scanning Electron Microscopy. [PDF]

J Morphol
ABSTRACT Hermit crabs rely on external shells for protection due to their non‐calcified pleons. This study focuses on the anatomical features and functional roles of various appendages in Calcinus tibicen to understand their mechanisms for shell anchoring.

Chemodiversity of Essential Oils From Eugenia uniflora L. Collected in Different Phytophysiognomies of the Coastal Region of Rio de Janeiro. [PDF]

Chem Biodivers
Essential oils from Eugenia uniflora collected in different coastal phytophysiognomies of Rio de Janeiro showed notable chemodiversity. GC‐MS and GC‐FID analyses revealed nine chemotypes, mainly rich in curzerene and selina‐1,3,7(11)‐trien‐8‐one. ABSTRACT This study aimed to evaluate the yield, color, and chemical composition of Eugenia uniflora ...

Adapting the growth-form concept to geniculate coralline algae (Corallinales, Rhodophyta). [PDF]

J Phycol
Abstract Geniculate coralline algae (Corallinales, Rhodophyta) are a diverse group of calcifying macroalgae, loosely united by flexible upright axes formed by alternating calcified (intergenicula) and uncalcified segments (genicula), a trait that has independently arisen several times.

First report of articuliths (free-living geniculate corallines, Corallinales, Rhodophyta) in the northern hemisphere revealed during diversity surveys of Haida Gwaii, British Columbia, Canada. [PDF]

J Phycol
Abstract Free‐living coralline beds are typically composed of rhodoliths, or unattached non‐geniculate coralline algae. In 2017, the first beds comprised primarily of free‐living geniculate coralline algae, termed articuliths, were documented in Arraial do Cabo Bay in southeastern Brazil.

An updated classification of growth forms in non-geniculate coralline algae (Corallinophycidae, Rhodophyta). [PDF]

J Phycol
Abstract The current challenge of defining growth forms in the non‐geniculate coralline red algae was addressed. Since the 19th century, those who have worked on this large and globally distributed group of algae have tried to summarize and systematically describe their growth forms. This effort resulted in a plethora of terms, which could sometimes be
