Parallel changes in genital morphology delineate cryptic diversification of planktonic nudibranchs. [PDF]

open access: yesProc Biol Sci, 2013
The relative roles of geographical and non-geographical barriers in the genesis of genetic isolation are highly debated in evolutionary biology, yet knowing how speciation occurs is essential to our understanding of biodiversity.

Narrowly defined taxa on a global scale: The phylogeny and taxonomy of the genera Catriona and Tenellia (Nudibranchia, Trinchesiidae) favours fine‐scale taxonomic differentiation and dissolution of the “lumpers & splitters” dilemma

open access: yesEvolutionary Applications, Volume 16, Issue 2, Page 428-460, February 2023., 2023
Abstract By applying morphological and molecular data on two genera of the nudibranch molluscs it is shown that the tension between taxonomic practice and evolutionary processes persists. A review of the related genera Catriona and Tenellia is used to demonstrate that the fine‐scale taxonomic differentiation is an important tool in the integration of ...

Heterotopic Gastric Mucosa Causing Rectal Bleeding in a Young Child

open access: yesJPGN Reports, Volume 3, Issue 2, May 2022., 2022
Heterotopic gastric mucosa (HGM) in the colon and small bowel is a very rare finding. We report a case of HGM in the rectum of an 8‐year‐old child with a history of eosinophilic esophagitis after having a colonoscopy to evaluate for inflammatory bowel disease. The colonoscopy was normal except for rectal tissue erythema and edema.

Ingestion and Toxicity of Polystyrene Microplastics in Freshwater Bivalves

open access: yesEnvironmental Toxicology and Chemistry, Volume 40, Issue 8, Page 2247-2260, August 2021., 2021
Microplastic ingestion by freshwater mussels depends on the exposure time, body size, food availability, and microplastic concentration. Polystyrene fragments (≤63 µm) affected mussels' clearance rate but not mortality, energy reserves, or oxidative stress. PS = polystyrene; MP = microplastics.
