Connectivity and Population Structure in a Marginal Sea—A Review
Diversity and Distributions, Volume 31, Issue 7, July 2025.ABSTRACT Aim The current biodiversity crisis calls for conservation measures that limit or reduce the negative human impact on key habitats and vulnerable wild populations. To effectively protect biodiversity at all levels, including intra‐specific diversity, conservation measures should, ideally, be aligned with the connectivity and genetic structure ...

An unusual membrane system in the oocyte of the ascidian Botryllus schlosseri
Tissue and Cell, 1994 During vitellogenesis, oocytes of Botryllus schlosseri always exhibit an unusual system scattered in the cytoplasm. It consists of an association between a single fenestrated endoplasmic reticulum cisterna and one or a few smooth vesicles (cisterna vesicle association: CVA) containing a dense core facing the cisterna itself.

Journal of the World Aquaculture Society, Volume 56, Issue 3, June 2025.Abstract Biofouling‐induced increases in labor costs are among the most impactful factors determining the technoeconomic feasibility and profitability of aquaculture operations. Understanding how different cultivation methods and environmental conditions influence the severity of biofouling is crucial to support informed decision‐making by farmers and ...

Insights on cytotoxic cells of the colonial ascidian Botryllus schlosseri [PDF]
Invertebrate Survival Journal, 2015 Morula cells (MCs) represent the most abundant circulating hemocyte of the compound ascidian Botryllus schlosseri. They are cytotoxic cells involved in the rejection reaction between contacting, genetically incompatible colonies.

Modular co-option of cardiopharyngeal genes during non-embryonic myogenesis
EvoDevo, 2019 Background In chordates, cardiac and body muscles arise from different embryonic origins. In addition, myogenesis can be triggered in adult organisms, during asexual development or regeneration.

Squishy and Crunchy Invasive Invertebrates: Environmental DNA Is Not Shed Equally
Environmental DNA, Volume 7, Issue 2, March/April 2025.Environmental DNA has been used to detect invasive species in aquatic ecosystems with varying degrees of success. Here, using laboratory experiments and a two‐year time series, we found that squishy species (those lacking an exoskeleton) generally shed eDNA consistently with their abundance, whereas crunchy species (those with a shell or exoskeleton ...

Ecology and Evolution, Volume 15, Issue 1, January 2025.ABSTRACT A new species of the genus Microcosmus was described in this study based on specimens collected from the coast of Xilian Town, Xuwen County, Zhanjiang, Guangdong Province, China. The morphological and molecular characteristics of this new species, Microcosmus sp. z YZ‐2024 (YZ‐2024), distinguish it from other sea squirts.

Kin Competition Drives the Evolution of Earlier Metamorphosis
Ecology and Evolution, Volume 15, Issue 1, January 2025.We develop a mathematical model to investigate how kin selection shapes the optimal timing of metamorphosis. We consider the full range of larval competition intensities and the full range of relatedness coefficients. This yields testable predictions as to how kin selection modulates the timing of metamorphosis.
