Expression of phenotypic plasticity depends on reaction norms adapted to historic selective regimes; anthropogenic changes in these selection regimes necessitate contemporary evolution or extirpation. Adaptation of conditional strategies following a change in the...

The development of citizen science has brought together scientific expertise and volunteer involvement to answer both scientific and societal questions. In this study, a consortium of citizens, journalist, scientists and non governmental organisations reports the...

The abundance and species richness of the cartilaginous fish community of the continental shelf and slope off central Chile is described, based on fishery-independent trawl tows made in 2006 and 2007. A total of 194,705 specimens comprising 20 species (9 sharks,...

A real dynamic population model calculates change in population sizes independent of time. The Beverton & Holt (B&H) model commonly used in fish assessment includes the von Bertalanffy growth function which has age or accumulated time as an independent variable....

We built climate envelope models under contemporary and future climates to explore potential range shifts of the invasive Red Shiner-Cyprinella lutrensis. Our objective was to estimate aquatic habitat vulnerability to Red Shiner invasion in North America under...

Background. The identification and characterisation of appropriate management units (stocks) is important as a basis for responsible fisheries management as well as conservation of within species biodiversity. The Banggai cardinalfish Pterapogon kauderni (F.P....

Understanding patterns of larval dispersal is key in determining whether no-take marine reserves are self-sustaining, what will be protected inside reserves and where the benefits of reserves will be observed. However, explicitly incorporating dispersal data into...

The directed harvest and global trade in the gill plates of mantas, and other mobulid rays, has led to increased fishing pressure and steep population declines in some locations. The slow life history, particularly of the manta rays, is cited as a key reason why...

The wasteful practice of discarding catch is one of the major problems associated with European fisheries. Despite this, estimates of discarded catch are not included in the ‘Official Catch Statistics’ database (1905 to present) collected and maintained by the...

Mumby et al. (2011) tested the biotic resistance hypothesis by comparing the biomass of invasive lionfish (introduced from the Indo-Pacific) and native grouper (Serranidae) at 12 sites within and adjacent to the Exuma Cays Land and Sea Park, The Bahamas. They reported...

Biotic resistance is the idea that native species negatively affect the invasion success of introduced species. We tested the hypothesis that native grouper are controlling the abundance of exotic lionfish on Caribbean coral reefs by assessing the relationship...

Background: The whale shark feeding aggregation in the Seychelles has been studied in detail since 2002, including aerial survey and collection of environmental data. In these coastal waters previous tagging studies have shown whale sharks spend considerable time...

The purpose of this study was to infer the possible impact of unmonitored discard of by-catch on a recreational fishery. We recorded by-catch of fishes at a recreational fishery in Northeast Texas, statistically analyzed them, and then projected estimates of mortality...

Characterization of DNA methylation patterns in the Pacific oyster, Crassostrea gigas, indicates that this epigenetic mechanism plays an important functional role in gene regulation and may be involved in the regulation of developmental processes and environmental...

The spotted sand bass (Paralabrax maculatofasciatus) is an important recreational sport and subsistence food fish within San Diego Bay, a large industrialized harbor in San Diego, California. Despite this importance, few studies examining the species life history...
