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 ...

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.

Morphological Characteristics, Mitochondrial Genome, and Evolutionary Insights Into a New Sea Squirt From the Beibu Gulf

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.

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.

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.

Sublethal exposure of eastern oyster Crassostrea virginica to the goniodomin‐producing dinoflagellate Alexandrium monilatum: Fate of toxins, histopathology, and gene expression

Journal of Aquatic Animal Health, Volume 36, Issue 4, Page 374-394, December 2024.
Abstract Objective The dinoflagellate Alexandrium monilatum forms blooms during summer in tributaries of the lower Chesapeake Bay. Questions persist about the potential for A. monilatum to negatively affect aquatic organisms. Its main toxin, goniodomin A (GDA), a polyketide macrolide, has been shown to have adverse effects on animals, for example ...

Phenoloxidase and cytotoxicity in the compound ascidian Botryllus schlosseri

Developmental & Comparative Immunology, 1998
The vacuoles of morula cells (MC) of the colonial ascidian Botryllus schlosseri contain phenoloxidase (PO). As the release of their vacuolar content at the border of incompatible contacting colonies is associated with the formation of necrotic masses which characterize the rejection reaction, the role of PO in Botryllus cytotoxicity was investigated ...

Mitochondria: great balls of fire

The FEBS Journal, Volume 291, Issue 24, Page 5327-5341, December 2024.
What are the implications of hot mitochondria? Recent experimental studies indicate that mitochondria in mammalian cells are maintained at temperatures of at least 50 °C. Here, we consider the ramifications of this finding for cellular functions, evolution, and disease.

A Method for Conveying Confidence in iNaturalist Observations: A Case Study Using Non‐Native Marine Species

Ecology and Evolution, Volume 14, Issue 10, October 2024.
Data quality, reliability and accuracy have long been recognised as barriers to unlocking the full potential of citizen science derived data. This study developed a score to assign confidence in iNaturalist observations and streamline the verification process.

Deep quantitative proteomics of North American Pacific coast star tunicate (Botryllus schlosseri)

PROTEOMICS, Volume 24, Issue 15, August 2024.
Abstract Botryllus schlosseri, is a model marine invertebrate for studying immunity, regeneration, and stress‐induced evolution. Conditions for validating its predicted proteome were optimized using nanoElute® 2 deep‐coverage LCMS, revealing up to 4930 protein groups and 20,984 unique peptides per sample.
