Overlap of nonbreeding wandering albatrosses with fisheries and implications for colony‐specific population trajectories at South Georgia

open access: yesConservation Biology, EarlyView.
Abstract Bycatch in fisheries is one of the most serious threats to pelagic seabirds, causing major population declines. Mitigation measures can reduce bycatch substantially, but many fisheries fail to apply best practices, and seabird mortality remains high.

A simplified semi-empirical model for multifrequency seafloor backscattering angular response (ESAB)

open access: yesFrontiers in Remote Sensing
A new approach to seafloor acoustic backscatter prediction and inversion is presented here and applied to an experimental dataset. Based on a frequency-dependent semi-empirical geometrical-physical description, the Extended Seabed Acoustic Backscatter ...

Preliminary use of oxygen stable isotopes and the 1983 El Niño to assess the accuracy of aging black rockfish (Sebastes melanops) [PDF]

open access: yes, 2005
Black rockfish (Sebastes melanops) range from California to Alaska and are found in both nearshore and shallow continental shelf waters (Love et al., 2002). Juveniles and subadults inhabit shallow water, moving deeper as they grow. Generally, adults are

Assessing differences among elasmobranch nurseries to aid conservation based on a genomics framework

open access: yesConservation Biology, EarlyView.
Abstract Elasmobranch nurseries often differ in environmental conditions, demographics, and use patterns. These differences affect the distribution of genetic variation among nurseries. However, conservation and management strategies often fail to account for such differences because they are difficult to characterize.

Sources and mechanisms for the enrichment of highly reactive iron in euxinic Black Sea sediments [PDF]

open access: yes, 2004
The deep basinal euxinic sediments of the Black Sea are enriched in iron that is highly susceptible to sulfidization compared to oxic/suboxic continental margin sediments in the Black Sea and oxic/dysoxic continental margin and deep-sea sediments ...

Reconsidering the role of introduced species in the climate‐affected and highly invaded eastern Mediterranean

open access: yesConservation Biology, EarlyView.
Abstract Bioinvasions are considered mostly as a biodiversity and conservation hazard, but in specific situations, introduced species can bring ecological or socioeconomic benefits. We assessed the social–ecological role of marine introduced species in the eastern Mediterranean Sea—a global hotspot of bioinvasions and extirpations—and their potential ...
