Comparative immunogenomics of molluscs [PDF]

open access: yesDevelopmental & Comparative Immunology, 2017
Comparative immunology, studying both vertebrates and invertebrates, provided the earliest descriptions of phagocytosis as a general immune mechanism. However, the large scale of animal diversity challenges all-inclusive investigations and the field of immunology has developed by mostly emphasizing study of a few vertebrate species.

Evaluation of Candidates for Systemic Analgesia and General Anesthesia in the Emerging Model Cephalopod, Euprymna berryi

open access: yesBiology, 2023
Cephalopods’ remarkable behavior and complex neurobiology make them valuable comparative model organisms, but studies aimed at enhancing welfare of captive cephalopods remain uncommon.

Distribution and diversity of commercial mollusc species at shallow depths in the Saloum delta, Senegal

open access: yesFrontiers in Marine Science
Shellfish harvesting in Saloum Islands is crucial for economic and socio-cultural income, particularly for women. However, the industry is facing decline in stocks and harvested individuals, necessitating urgent shellfish assessment and mapping in the ...

Sexual selection gradients change over time in a simultaneous hermaphrodite

open access: yeseLife, 2017
Sexual selection is generally predicted to act more strongly on males than on females. The Darwin-Bateman paradigm predicts that this should also hold for hermaphrodites.

Nitric oxide is not a negative regulator of metamorphic induction in the abalone Haliotis asinina

open access: yesFrontiers in Marine Science, 2014
Nitric oxide (NO) is a second messenger molecule synthesized by the enzyme nitric oxide synthase (NOS) that requires the molecular chaperone heat shock protein 90 (HSP90) for normal enzymatic activity.

Neuro-endocrine control of reproduction in hermaphroditic freshwater snails: mechanisms and evolution

open access: yesFrontiers in Behavioral Neuroscience, 2010
Invertebrates are used extensively as model species to investigate neuro-endocrine processes regulating behaviours, and many of these processes may be extrapolated to vertebrates.

Investigation of the electrophilic reactivity of the biologically active marine sesquiterpenoid onchidal and model compounds

open access: yesBeilstein Journal of Organic Chemistry, 2018
The structure of the sesquiterpene onchidal (6), a component of the defensive secretion of the shell-less mollusc Onchidella binneyi, contains a masked α,β-unsaturated 1,4-dialdehyde moiety, the presence of which has been proposed to be the cause of the ...

Maintenance of Octopus vulgaris Type II paralarvae in an estuarine area

open access: yesRevista Brasileira de Zootecnia, 2018
We assessed the survival of paralarvae kept in a floating wooden box attached to an oyster extensive cultivation system with no extra food supply. A total of 7700 newly hatched paralarvae were maintained in a 10.5-L floating box (7 cm height × 30 cm ...

Predicting the Response of Molluscs to the Impact of Ocean Acidification

open access: yesBiology, 2013
Elevations in atmospheric carbon dioxide (CO2) are anticipated to acidify oceans because of fundamental changes in ocean chemistry created by CO2 absorption from the atmosphere.
