Around the globe, coral reefs and other marine ecosystems are increasingly overfished. Conventionally, studies of fishing impacts have focused on the population size and dynamics of targeted stocks rather than the broader ecosystem-wide effects of harvesting. Using parrotfishes as an example, we show how coral reef fish populations respond to escalating fishing pressure across the Indian and Pa...

The choice to conserve or be greedy in a commons dilemma may be influenced by the behavior of others and by pro-environmental values. Participants completed a measure of pro-environmental values one week before taking part in an Internet-based commons dilemma microworld consisting of a shared fishery with three computer-controlled virtual fishers whom participants believed to be real people. Th...

Tuna fisheries around the world are governed by Regional Fishery Management Organizations (RFMOs), whose membership includes both harvesting nations and nations in whose waters the targeted fish populations reside. The outcomes of the policies established by an RFMO will depend on subsequent interactions among the fleets, the fishing sites and the RFMO itself – an interplay that can be formally...

BACKGROUND Conventional autologous skin grafts are associated with significant donor-site morbidity. This study was conducted to determine feasibility, safety, and efficacy of a new strategy for skin grafting based on harvesting small columns of full-thickness skin with minimal donor-site morbidity. METHODS The swine model was used for this study. Hundreds of full-thickness columns of skin ti...

Size-selective harvesting is one of the most widespread anthropogenic impacts on marine species. The loss of larger (older) individuals due to such harvesting has numerous cascading effects on the biology of affected species and populations, including changes in life history, demography, reproductive output, and even ecological interactions (Fenberg & Roy 2008). Size-selective harvesting has be...

Sustainable harvesting of wild populations relies on evidence-based knowledge to predict outcomes for species and the ecosystems they inhabit. Although may elicit compensatory density-dependence, it is generally size-selective, which induces additional pressures that are challenging forecast. Furthermore, responses harvest be population-specific whether generalizable patterns exist remains uncl...
