Evidence for adaptive explanations of semelparity in animals
Biological Reviews, EarlyView.ABSTRACT Semelparity, the reproductive strategy of reproducing once, is widespread but uncommon in animals. Classes of models to explain the evolution of semelparity are based either on age structure and mortality schedules – demographic models in which high post‐reproductive mortality risk favours high reproductive effort and semelparity results from ...

New Contributions to the Euthyneura Biodiversity of Colombia’s Pacific and Caribbean Coasts
DiversityThe infraclass Euthyneura (Mollusca, Heterobranchia) exhibits significant diversity in morphology, size, life habits, and color. Several species are important for research in evolution, ecology, chemistry, and pharmacology.

Gene Expression and Structural Differences Underpinning Black and White Colouration in Spiders
Molecular Ecology, Volume 35, Issue 12, June 2026.ABSTRACT The presence of multiple color variants within a single population, known as color polymorphism, is a striking example of intraspecific phenotypic variation and a model for studying evolutionary processes. These processes depend on the underlying mechanisms such as the genes and pigments involved; but we currently lack such information for non‐

Oxygenated Terpenes from the Indo-Pacific Nudibranchs and
Natural Product Communications, 2018 Three new terpenes each with a highly oxygenated or rearranged spongian framework were characterized from organic extracts of the nudibranchs G. splendidus and G. collingwoodi collected from Eastern Australia.

New Records of Four Doridoidean Nudibranchs from Korea [PDF]
Animal Systematics, Evolution and Diversity, 2013 Specimens of nudibranchs have been surveyed by scuba diving from 9 localities along the Korean coast. By examination of morphological characteristics, four species in the superfamily Doridoidea which are new to Korea were identified, and re-described ...

Molecular Ecology, Volume 35, Issue 12, June 2026.ABSTRACT Southern right whale (Eubalaena australis; SRW) populations are recovering from the impacts of commercial whaling, however, recovery has been spatially variable, with strong associations between reproduction and prey availability. The diet of SRWs has not been widely examined, and with SRW foraging shifting away from high‐latitude foraging ...

Mollusca, Nudibranchia: new records and southward range extensions in Santa Catarina, southern Brazil [PDF]
Check List, 2011 Nudibranch molluscs constitute a group of marine gastropods little studied in most of the Brazilian coast extension. Up to date, only ten species are known from Santa Catarina state, southern Brazil.

Feeding in nudibranch larvae [PDF]
Journal of the Marine Biological Association of the United Kingdom, 1959 No account exists of the mechanism of food collection of nudibranch larvae, and, in fact, it has been considered unlikely that feeding does take place in these forms. Thorson (1946, p. 275) states ‘Nudibranch larvae will normally take no—or only little—food from the plankton’.

Ecology and Evolution, Volume 16, Issue 5, May 2026.We compared the traditional two‐dimensional (2D: δ13C and δ15N) isotopic niches with a three‐dimensional (3D: δ13C, δ15N, and δ34S) framework to evaluate changes in niche size and overlap. Overall, invertebrates and benthic‐associated species showed greater changes in niche size and reduced overlap using the 3D approach.
