In May 2006, the Australian Government released its final plan for a representative network of MPAs in the country’s South-east Region, comprising a proposal for 13 new MPAs in Commonwealth waters. Totaling 226,000 km, the MPA network is substantially larger than a proposal the government released in December 2005 (171,000 km), yet reportedly will have a 90% lower impact on commercial fisheries...
Message passing algorithms (MPAs) are an algorithmic paradigm for the following generic problem: given a system consisting of several interacting components, compute a new version of each component representing its behaviour inside the system. MPAs avoid computing the full state space by propagating messages along the edges of the system interaction graph. We present an MPA for verifying local ...
Incorporating warming disturbances into the design of marine protected areas (MPAs) is fundamental to developing appropriate conservation actions that confer coral reef resilience. We propose an MPA design approach that includes spatially- and temporally-varying sea-surface temperature (SST) data, integrating both observed (1985-2009) and projected (2010-2099) time-series. We derived indices of...
Meta-analyses of field studies have shown that biomass, density, species richness, and size of organisms protected by no-take marine reserves generally increase over time. The magnitude and timing of changes in these response variables, however, vary greatly and depend upon the taxonomic groups protected, size and type of reserve, oceanographic regime, and time since the reserve was implemented...
There is broad interest in the development of efficient marine protected areas (MPAs) to reduce bycatch and end overfishing of speckled hind (Epinephelus drummondhayi) and warsaw grouper (Hyporthodus nigritus) in the Atlantic Ocean off the southeastern U.S. We assimilated decades of data from many fishery-dependent, fishery-independent, and anecdotal sources to describe the spatial distribution...
The MBNMS study area appears to be heavily protected from overfishing and the many layers of regulations from the different management agencies prevent a large number of exploitable species from being fished at any appreciable level. This is particularly true of species in soft bottom areas of the nearshore and shelf habitats, the shelf break habitat, the deep slope habitat and the rise habitat...
BACKGROUND A prospective randomized study was used to compare surgery times for laparoscopic ovariectomy and salpingectomy in female African lion (Panthera leo) (n = 14) and cheetah (Acinonyx jubatus) (n = 20) and to compare the use of a multiple portal access system (MPAS) and single portal access system (SPAS) between groups. Two different portal techniques were used, namely MPAS (three separ...
This month’s First International Marine Protected Areas Congress (IMPAC1), to be held 23-28 October in Geelong, Australia, is one of the first global conferences devoted solely to the subject of MPAs. Hopefully many more will follow. Unanswered questions still abound on aspects of MPA science (e.g. the effects of reserves on neighboring fisheries) and on best practices in planning and managemen...
