Twins! Microsatellite analysis of two embryos within one egg case in oviparous elasmobranchs.

PLoS ONE, 2019
Elasmobranchs display various reproductive modes, which have been key to their evolutionary success. In recent decades there has been a rise in the number of reported cases of foetal abnormalities including fertilised, double-embryos held within one egg ...

The fin-to-limb transition as the re-organization of a Turing pattern

Nature Communications, 2016
Mouse digit patterning is controlled by a Turing network of Bmp, Sox9, and Wnt. Here, Onimaru et al. show that fin patterning in the catshark, Scyliorhinus canicula, is controlled by the same network with a different spatial organization; thus, the ...

Classification of sharks in the Egyptian Mediterranean waters using morphological and DNA barcoding approaches. [PDF]

PLoS ONE, 2011
The identification of species constitutes the first basic step in phylogenetic studies, biodiversity monitoring and conservation. DNA barcoding, i.e. the sequencing of a short standardized region of DNA, has been proposed as a new tool for animal species

Key drivers of at-vessel mortality in demersal sharks. [PDF]

Conserv Biol
Abstract Chondrichthyans are highly vulnerable to fisheries overexploitation, and postcapture mortality poses a significant threat to most species. Global bycatch mitigation guidelines recommend adopting hierarchical decision‐making approaches tailored to species‐specific vulnerabilities and socioeconomic and regulatory contexts.
