Species which may act as vectors or reservoirs of diseases covered by the Animal Health Law: Listed pathogens of crustaceans. [PDF]

EFSA J, 2023
Abstract Vector or reservoir species of three diseases of crustaceans listed in the Animal Health Law were identified based on evidence generated through an extensive literature review, to support a possible updating of Regulation (EU) 2018/1882.

Nematopsis Schneider, 1892 in Nerite Gastropods From Saint Kitts, With a Phylogenetic Study of the Genus, and Placement Within the Phylum Apicomplexa Levine, 1970. [PDF]

J Eukaryot Microbiol
ABSTRACT The Apicomplexa are obligate unicellular parasites found in terrestrial and aquatic environments. Nematopsis are found infecting marine invertebrates in a life cycle involving mollusks and crustaceans. In the present study, mantle and muscle tissues from nerite gastropods were microscopically examined for Nematopsis using wet mounts and ...

Biomineralized Materials as Model Systems for Structural Composites: Intracrystalline Structural Features and Their Strengthening and Toughening Mechanisms. [PDF]

Adv Sci (Weinh), 2022
The mineral building blocks in biomineralized composites exhibit salient intracrystalline structural features, such as organic inclusions, trace elements, varying crystalline features, residual stress/strain, and twinning, which significantly modifies the mechanical properties of biogenic minerals.

A survey of Dinophysis spp. and their potential to cause diarrhetic shellfish poisoning in coastal waters of the United States

Journal of Phycology, Volume 59, Issue 4, Page 658-680, August 2023., 2023
Abstract Multiple species of the genus Dinophysis produce diarrhetic shellfish toxins (okadaic acid and Dinophysis toxins, OA/DTXs analogs) and/or pectenotoxins (PTXs). Only since 2008 have DSP events (illnesses and/or shellfish harvesting closures) become recognized as a threat to human health in the United States.

Is Ocean Acidification Really a Threat to Marine Calcifiers? A Systematic Review and Meta‐Analysis of 980+ Studies Spanning Two Decades

Small, Volume 18, Issue 35, September 1, 2022., 2022
Marine calcifiers are widely believed to be impaired by ocean acidification, but this concept has been increasingly challenged by recent evidence. This systematic review and meta‐analysis of nearly 1000 studies reveal that many calcifiers are indeed more resistant to ocean acidification than initially thought, which can result from the positive effects

Biomineralized Materials as Model Systems for Structural Composites: 3D Architecture

Advanced Materials, Volume 34, Issue 20, May 19, 2022., 2022
Biomineralized load‐bearing materials are intrinsically 3D composites and are widely used as model systems for developing novel structural materials with improved mechanical performance. This review presents recent progress in understanding the 3D architectural design of biomineralized composites.

Testing small‐scale ecological gradients and intraspecific differentiation for hundreds of kelp forest species using haplotypes from metabarcoding

Molecular Ecology, Volume 30, Issue 13, Page 3355-3373, July 2021., 2021
Abstract DNA metabarcoding has been increasingly used to detail distributions of hundreds of species. Most analyses focus on creating molecular operational taxonomic units (MOTUs) from complex mixtures of DNA sequences, but much less common is use of the sequence diversity within these MOTUs.

Shellfish subsidies along the Pacific coast of North America

Ecography, Volume 43, Issue 5, Page 668-681, May 2020., 2020
Spatial subsidies are associated with pronounced ecosystem responses, as nutrients cross ecological boundaries and cascade through food webs. While the importance of subsidies is known, the role of shellfish, specifically molluscs, as a marine subsidy has not been formally described. Focusing primarily on the Pacific coast of North America, we identify

Precarious livelihoods: Examining the intersection of fish work and ecological change in coastal Jamaica

People and Nature, Volume 2, Issue 1, Page 152-162, March 2020., 2020
Abstract Precarity has not been applied in the context of fisheries‐based work, even as working conditions in fisheries are emerging to be a real issue. There has been limited analysis of fish work outside the media spotlight or how changing ecological and biophysical conditions (e.g.

Multiple Twinning in Nacre and Aragonite

Advanced Functional Materials, Volume 36, Issue 20, 9 March 2026.
Electron backscatter diffraction map of a cluster of geologic aragonite, exhibiting single, double, and triple twins. The whole cluster is approximately 2 cm wide. Colors indicate crystal orientations, so that pixels where the a‐, b‐, and c‐axis is perpendicular to the image plane are green, red, and blue, respectively.
