On the origin of Acochlidia and other enigmatic euthyneuran gastropods, with implications for the systematics of Heterobranchia

BMC Evolutionary Biology, 2010
BackgroundA robust phylogenetic hypothesis of euthyneuran gastropods, as a basis to reconstructing their evolutionary history, is still hindered by several groups of aberrant, more or less worm-like slugs with unclear phylogenetic relationships.

Prioritising research on endocrine disruption in the marine environment: a global perspective

Biological Reviews, EarlyView.
ABSTRACT A healthy ocean is a crucial life support system that regulates the global climate, is a source of oxygen and supports major economic activities. A vast and understudied biodiversity from micro‐ to macro‐organisms is integral to ocean health.

Cretaceous Nerineacean gastropods [PDF]

, 1989
The Nerineacea form a distinctive and significant component of shallow marine Mesozoic Tethyan macrofaunas. They occur in shelf sediments deposited in tropical regions during the Jurassic and Cretaceous. The group first appears in the early Jurassic and high diversity levels had developed by late Jurassic and early Cretaceous times.

Monitoring small‐scale fisheries through participatory, app‐based surveys in the tropical archipelago of São Tomé and Príncipe

Conservation Science and Practice, EarlyView.
Small Island Developing States have limited capacity to monitor Small Scale Fisheries, despite their high dependence on marine resources. Participatory monitoring of Small Scale Fisheries can fill data gaps while integrating resource users into fisheries management.

Susceptibility of the early growth stages of volunteer oilseed rape to invertebrate predation

Plant Protection Science, 2012
Chemical and agronomical control of volunteer plants is difficult, especially in reduced-input cropping systems where feeding by natural herbivores may become an important cause of their mortality.

Sclerite formation in the hydrothermal-vent “scaly-foot” gastropod — possible control of iron sulfide biomineralization by the animal [PDF]

, 2006
A gastropod from a deep-sea hydrothermal field at the Rodriguez triple junction, Indian Ocean, has scale-shaped structures, called sclerites, mineralized with iron sulfides on its foot.

Early Elements in Gastropod Neurogenesis

Developmental Biology, 1996
The first elements of the nervous system of pond snails appear in the very early veliger stage of development at much earlier times than any previously described neurons. The first three cells are reactive to antibodies raised against both the neuropeptide FMRFamide and tubulin and their somata are located posteriorly within the embryo, not in anterior

Spatial habitat partitioning enables coexistence of three Gobiidae species in estuarine environments

Journal of Fish Biology, EarlyView.
Abstract This study examines resource partitioning (feeding morphology, diet and habitat partitioning) among three gobiid species, the Knysna sandgoby Psammogobius knysnaensis, the prison goby Caffrogobius gilchristi and the river goby Glossogobius callidus, within an estuarine environment.

Nonapeptide cell size differs between male morphs of the West African cichlid, Pelvicachromis pulcher

Journal of Fish Biology, EarlyView.
Abstract Alternative male morphs are found in many species of fishes. These morphs often differ in suites of social behaviours, such as aggression and territoriality, associated with alternative reproductive tactics. Such consistent morph‐typical behavioural profiles suggest common differences in underlying neuroendocrine mechanisms.
