Genetic considerations for mollusc production in aquaculture: current state of knowledge.

open access: yesFrontiers in Genetics, 2014
IIn 2012, world mollusk production in aquaculture reached a volume of 15,171,000 tons, representing 23% of total aquaculture production and positioning mollusks as the second most important category of aquaculture products (fishes are the first).

Bryozoan‐Rich Carbonate Units of the Erfoud Area (SE Morocco) Record Latest Katian to Early Hirnantian Interglacial Intervals

open access: yesGeological Journal, EarlyView.
In this study, we re‐examine the depositional architecture of the Erfoud limestone in Morocco. Introducing new biostratigraphic constraints from chitinozoan assemblages, we show that Katian to Hirnantian bryozoan‐pelmatozoan meadows reflect flooding events linked to a series of interglacial transgressions known to have occurred immediately prior to the

Nanoplastics: Methods, Exposure and Effects on Domestic, Farm and Wild Animals

open access: yesJournal of Applied Toxicology, EarlyView.
ABSTRACT Nanoplastics (NPs) are synthetic polymer particles ranging in size from 1 nm to 1 μm that have been identified as a major concern for ecosystems and organisms due to their plethora of negative effects. The aim of this review is to provide a comprehensive overview of the knowledge relating to exposure and effects of NPs in domestic (i.e., farm ...

The Minimal Nonplanar Strong Digraphs

open access: yesJournal of Graph Theory, EarlyView.
ABSTRACT Kuratowski's theorem says that the minimal (under subgraph containment) graphs that are not planar are the subdivisions of K 5 ${K}_{5}$ and of K 3 , 3 ${K}_{3,3}$. Here we study the minimal (under subdigraph containment) strongly‐connected digraphs that are not planar.

Morphological characterization of the hemocytes of the pulmonate snail Biomphalaria tenagophila

open access: yesMemorias do Instituto Oswaldo Cruz, 1993
The blood cells of the pulmonate snail Biomphalaria tenagophila, an important transmiter of the trematode Schistosoma mansoni in Brazil, were examined by ligth and transmission electron microscopy (TEM).

Stable isotope analysis of freshwater gastropod carbonates from Swanscombe: Insights into climate stability and seasonality during MIS 11c

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT Stable isotope analyses of freshwater mollusc carbonate can record environmental conditions at the time of mineralisation, yet this technique remains underused in British Middle Pleistocene fluvial sequences, despite the abundance of fossil shell material in these deposits.

Anaerobically functioning mitochondria: evolutionary perspective on modulation of energy metabolism in Mytilus edulis

open access: yesInvertebrate Survival Journal, 2015
The mitochondrion represents a compelling biological model of complex organelle development driven by evolutionary modification of permanently enslaved primordial purple non-sulphur bacteria.
