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 ...

Studying Fauna of Parthenites and Trematoda Larvae of Fresh-Water Crimean Mollusks

open access: yes, 1976
During four seasons of 1970-1973 8763 mollusks of 17 species from reservoirs, rivers and ponds of the Crimea were studied. Cercaria of 24 Trematoda species belonging to 15 genera from 12 families and metacercaria of 5 species are found in the mollusks ...

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 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.

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 ...

Agri‐food Trade between Visegrad Countries and Taiwan: Opportunities, Limitations and Twists and Turns Commerce agroalimentaire entre les pays du groupe de Visegrad et Taïwan : Opportunités, limites et rebondissements Agrar‐ und Lebensmittelhandel zwischen den Visegrad‐Ländern und Taiwan: Chancen, Grenzen und Wendungen

open access: yesEuroChoices, EarlyView.
Summary This study examines the dynamics and potential of agri‐food trade between the Visegrad Four (V4) countries and Taiwan, using this regional case to highlight broader opportunities for EU–Taiwan economic engagement. While the V4 countries have not historically been major agri‐food trading partners with Taiwan, the analysis reveals untapped trade ...

Sensory Biology of the Franciscana (Pontoporia blainvillei, Pontoporiidae, Cetartiodactyla): Ontogenetic Modifications of Vibrissae and Vibrissal Crypts

open access: yesIntegrative Zoology, EarlyView.
The transition of cetaceans from a terrestrial to an aquatic environment involved a crucial sensory adaptation to environments with limited visibility. Vibrissae, important mechanoreceptors, undergo an ontogenetic transformation in odontocetes. This research describes the histomorphology of vibrissae and crypts at different developmental stages ...
