Variation in thermal tolerance plasticity and the costs of heat exposure in the estuarine sea hare, Phyllaplysia taylori

open access: yesEcosphere, Volume 16, Issue 2, February 2025.
Abstract Climate change is increasing average temperatures and the frequency and intensity of thermal extremes in coastal marine environments. Organisms in coastal marine habitats are accustomed to environmental fluctuations and possess physiological plasticity that may be advantageous in response to increased occurrence of extremes. To examine whether

Genomics of Terpene Biosynthesis in Dictyoceratid Sponges (Porifera) – What Do We (Not) Know?

open access: yesChemistry &Biodiversity, Volume 21, Issue 9, September 2024.
Abstract Sponges are recognized as promising sources for novel bioactive metabolites. Among them are terpenoid metabolites that constitute key biochemical defense mechanisms in several sponge taxa. Despite their significance, the genetic basis for terpenoid biosynthesis in sponges remains poorly understood.

A novel target‐enriched multilocus assay for sponges (Porifera): Red Sea Haplosclerida (Demospongiae) as a test case

open access: yesMolecular Ecology Resources, Volume 24, Issue 2, February 2024.
Abstract With declining biodiversity worldwide, a better understanding of species diversity and their relationships is imperative for conservation and management efforts. Marine sponges are species‐rich ecological key players on coral reefs, but their species diversity is still poorly understood.
