Resilience and recovery of overexploited marine populations.
Recovery of overexploited marine populations has been slow, and most remain below target biomass levels. A key question is whether this is due to insufficient reductions in harvest rates or the erosion of population resilience. Using a global meta-analysis of overfished stocks, we find that resilience of those stocks subjected to moderate levels of overfishing is enhanced, not compromised, offe...
متن کاملSignatures of the collapse and incipient recovery of an overexploited marine ecosystem
The Northwest Atlantic cod stocks collapsed in the early 1990s and have yet to recover, despite the subsequent establishment of a continuing fishing moratorium. Efforts to understand the collapse and lack of recovery have so far focused mainly on the dynamics of commercially harvested species. Here, we use data from a 33-year scientific trawl survey to determine to which degree the signatures o...
متن کاملPredation, competition, and the recovery of overexploited fish stocks in marine reserves
Community interactions alter the management actions necessary to recover overfished species using marine reserves. For example, in communities where a larger species preys on their juveniles’ competitors, overfishing of the larger species may cause prey population expansion; subsequent increased competition for the juveniles of the overfished species may impede its recovery within reserves. We ...
متن کاملP21: Local Administration of Methylprednisolone Laden Hydrogel Enhances Functional Recovery of Transected Sciatic Nerve in Rat
The repair of peripheral nerve injuries is still one of the most challenging tasks and concerns in neurosurgery. Effect of methylprednisolone-laden hydrogel loaded into a chitosan conduit on the functional recovery of peripheral nerve using a rat sciatic nerve regeneration model was assessed. A 10-mm sciatic nerve defect was bridged using a chitosan conduit (CHIT/CGP-Hydrogel) filled with CGP-h...
متن کاملThe use of COCOON in teaching silviculture
At the Institute of Silviculture at the University of Natural Resources and Applied Life Sciences, Vienna, students learn to cross-link ecological, socio-economic and technical knowledge of maintaining, regenerating, tending and utilizing forests in a sustainable way. They learn complex concepts and processes most successfully when they are actively engaged in the learning process. Therefore, t...
