A hedgehog-like signal is involved in slow muscle differentation in Sepia officinalis (Mollusca)

open access: yesInvertebrate Survival Journal, 2007
In the tentacle of Sepia officinalis, smooth-like, helical and cross-striated fibres deriving from different populations of myoblasts are present. Myoblasts appear at different times during the development and express two muscle-specific transcription ...

Rotenone Induces Morphological Damage and Reduction in Catecholamine Levels in the Central Nervous System of the Ascidian Styela plicata

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Ascidians are invertebrates that occupy a key phylogenetic position as a sister group of the vertebrates. The organization of their central nervous system (CNS), with cortex and medulla, indicates a plesiomorphic character of the gray and white matter of vertebrates, making this group of animals useful for studies of neurodegenerative events ...

Microplastics and the Endocrine–Metabolic Interface: Novel Diagnostic Tools Targeting Thyroid–Adipose Axis

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Microplastics (MPs) have been identified as major environmental contaminants that can affect organisms directly and act as carriers of particles and chemical additives, thereby aggravating endocrine networks that coordinate metabolic homeostasis.

Trace Element Contamination in Top Predatory Elasmobranchs From the Southern Black Sea: Implications for Ecosystem Health and Risk Assessment

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Environmental pollution resulting from the rapid increase in human population, urbanization, intensive use of chemicals in agriculture, and industrial development has reached a level that threatens natural life today. Trace elements are one of the most important factors causing significant levels of pollution in the environment and are added ...

Field evaluations of thermal optics and tracking tunnels for small mammal surveys at airports and grass dominated habitats

open access: yesWildlife Society Bulletin, EarlyView.
Small mammal survey tools are needed at airports to help inform aircraft strike‐risk management. We evaluated thermal optics and tracking tunnels as small mammal survey tools. We conclude that thermal optics would not be a viable survey tool for mouse‐sized mammals (19‐41 g) at airfields and other thick grass habitats unless grass height was maintained

Hydrodynamic gradients affect facilitation in soft sediment communities

open access: yesJournal of Animal Ecology, EarlyView.
This study extends ecological theory on facilitation to marine soft‐sediment systems and offers insight into the functional role of habitat‐forming infauna. Abstract Positive species interactions, or facilitation, are fundamental drivers of ecological community assembly and stability.

A global assessment of national vulnerability to ocean acidification through the mollusc industry.

open access: yes, 2017
Mollusc harvests have considerable economic and nutritional benefits globally. However, the ability of many mollusc species to reproduce, grow and survive is threatened by ocean acidification.

A reappraisal of the Middle to Later Stone Age prehistory of Morocco Réévaluer la préhistoire du Maroc, du Middle Stone Age au Later Stone Age

open access: yesJournal of the Royal Anthropological Institute, EarlyView.
Over the last 25 years, perceptions of the early prehistory of Northwest Africa have undergone radical changes due to new fieldwork projects and a corresponding growth in scientific interest in the region. Much of this work has been focused in Morocco, known for its extremely rich fossil and archaeological records in caves and rock shelters.

D-Aspartic Acid in the Nervous System of a Mollusc: An Immunohistochemical Protocol

open access: yes, 2009
D-Aspartic acid (D-Asp) was first detected by biochemical methods in the nervous tissue of cephalopod mollusc. Subsequently, this endogenous amino acid has been described in various tissues of the representatives of most vertebrate and invertebrate ...

False kings and imagined protestants: why schismogenesis does not explain variation in inequality among Indigenous societies of the Pacific Coast Faux rois et protestants imaginaires: pourquoi la schismogenèse n'explique pas les variations des inégalités parmi les sociétés autochtones de la côte pacifique nord‐américaine

open access: yesJournal of the Royal Anthropological Institute, EarlyView.
Indigenous societies along the temperate Pacific coast of North America embody diverse cultural institutions. This variation is conventionally classified into two distinct cultural areas: the Northwest Coast (NWC) and California (CAL). Discussion of the environmental, material, social, and ideological variation in these societies has a long and ...
