Exploring consumer preferences for wild meat and other animal proteins in Gamba, Gabon: Implications for conservation and management of natural resources alongside extractive industry

People and Nature, EarlyView.
Abstract The town of Gamba in southwest Gabon represents an exceptional example of how the development of an extractive industry (in this case oil production) may impact wild meat consumption in an area of global importance for biodiversity. Studies in the 1990s identified an active wild meat trade; however, no studies have been undertaken since, and ...

Biological invasions disrupt the relationship between size spectrum and trophic interactions in freshwater fish communities

Journal of Animal Ecology, EarlyView.
Our study shows that non‐native species alter the relationship between the size‐spectrum slope and the predator–prey mass ratio (PPMR) in freshwater fish communities by occupying distinct trophic niches. Abstract The size spectrum, which describes the relationship between abundance (or biomass) and body size, is an ataxic approach that can provide ...

Recovery of Four Commercial Fish Stocks in Lake IJsselmeer (The Netherlands) After Major Fishery Management Interventions

Fisheries Management and Ecology, EarlyView.
ABSTRACT Sustainable management of inland fisheries presents major challenges because it often involves complex and open access systems. Lake IJsselmeer is among the largest freshwater lakes in western Europe and supports active commercial fisheries.

Characterization data of gilthead sea bream (Sparus aurata) IGF-I receptors (IGF-IRa/Rb)

Data in Brief, 2016
In this data article we describe the coding sequence of two IGF-IR paralogues (IGF-IRa and IGF-IRb) obtained from gilthead sea bream embryos. The putative protein architecture (domains and other important motifs) was determined and, amino acid sequences ...

Application of Environmental DNA for Monitoring Red Sea Bream Iridovirus at a Fish Farm

Microbiology Spectrum, 2021
Red sea bream iridoviral disease (RSIVD) causes high economic damage in mariculture in Asian countries. However, there is little information on the source of infection and viral dynamics in fish farms. In the present study, the dynamics of RSIV in a fish

Territorial behavior in juvenile red sea bream Pagrus major and crimson sea bream Evynnis japonica

Fisheries Science, 2004
: The territorial behavior of juvenile red sea bream Pagrus major and crimson sea bream Evynnis japonica was examined at Morode Cove, Ehime Prefecture. Four exclusive types of behavior (attack, mutual attack, head down threat and mutual display) and one escaping behavior (fleeing) were observed in both species.

Dragonfly taxonomic and functional responses to urbanized streams in southeastern Europe, with management recommendations

Insect Conservation and Diversity, EarlyView.
Urbanization drives turnover in dragonfly species composition, traits, and habitat conservation value. Natural stream sections have a higher conservation value (higher DBI) due to presence of specialists. Properly managed urban streams can support diverse dragonfly assemblages.

Expression of corticoid‐regulatory genes in the gills of Atlantic salmon (Salmo salar) parr and smolt and during salinity acclimation

Journal of Fish Biology, EarlyView.
Abstract In teleost fishes, cortisol is the major corticoid and has both glucocorticoid and mineralocorticoid actions. However, how fish tissues discriminate between these distinct corticosteroid actions is unclear. In mammals, the major factors responsible for intracellular corticosteroid regulation are glucocorticoid receptors (grs) and the ...
