Comparative genomics of chondrichthyan Hoxa clusters

BMC Evolutionary Biology, 2009
Background The chondrichthyan or cartilaginous fish (chimeras, sharks, skates and rays) occupy an important phylogenetic position as the sister group to all other jawed vertebrates and as an early lineage to diverge from the vertebrate lineage following ...

Molecular markers reveal spatially segregated cryptic species in a critically endangered fish, the common skate (Dipturus batis) [PDF]

Proceedings of the Royal Society B: Biological Sciences, 2010
Many sharks and skates are particularly vulnerable to overfishing because of their large size, slow growth, late maturity and low fecundity. In Europe dramatic population declines have taken place in common skate (Dipturus batisL.), one of the largest demersal fish in regional shelf seas, leading to extirpations from substantial parts of its former ...

Commercial catches, reproduction and feeding habits of Raja asterias (Chondrichthyes: Rajidae) in a coastal area of the Tyrrhenian Sea (Italy, northern Mediterranean) [PDF]

Acta Adriatica, 2007
A total of 52 “rapido” (towed toothed beam gears) trawls were monitored in late winter-summer of the 1999-2000 period to assess the R. asterias size structure at this time of higher yields as well as 36 fishing operations performed by “volantina” (trawl ...

Recent advances in multifunctional soft robots: A materials–structures–systems co‐design perspective for synergistic integration

FlexMat, EarlyView.
Abstract Soft robots, engineered from highly compliant materials, offer superior adaptability and safety in unstructured environments compared to their rigid counterparts. Recent advancements, fueled by bio‐inspiration and material programmability, have led to the rapid co‐evolution of their core modules: actuation, sensing, protection, energy, and ...
