Effective conservation depends largely on people’s compliance with regulations. We investigate compliance through the lens of fishers’ compliance with marine protected areas (MPAs). MPAs are widely used tools for marine conservation and fisheries management. Studies show that compliance alone is a strong predictor of fish biomass within MPAs. Hence, fishers’ compliance is critical for MPA effec...

Minor Physical Anomalies (MPAs) are subtle abnormalities of the head, face, and limbs, without significant cosmetic or functional impact to the individual. They are assumed to represent external markers of developmental deviations during foetal life. MPAs have been suggested to indicate severity in mental illness and constitute external markers for atypical brain development. Higher frequencies...

Marine protected areas (MPAs) have attracted much attention as a tool for sustainable fisheries management, restoring depleted fisheries stocks and maintaining ecosystems. However, even with total exclusion of fishing effort, depleted stocks sometimes show little or no recovery over a long time period. Here, using a mathematical model, we show that multiple stable states may hold the key to und...

BACKGROUND A variety of human activities have led to the recent global decline of reef-building corals. The ecological, social, and economic value of coral reefs has made them an international conservation priority. The success of Marine Protected Areas (MPAs) in restoring fish populations has led to optimism that they could also benefit corals by indirectly reducing threats like overfishing, w...

Coral reefs and associated fish populations have experienced rapid decline in the Caribbean region and marine protected areas (MPAs) have been widely implemented to address this decline. The performance of no-take MPAs (i.e., marine reserves) for protecting and rebuilding fish populations is influenced by the movement of animals within and across their boundaries. Very little is known about Car...

Pollution caused by shipping accidents or by intentional discharge of harmful materials can be transported by currents to locations far from the source, and therefore poses a potential risk to marine protected areas (MPAs). The risk of current-driven pollution to MPAs in the Gulf of Finland is assessed by analysing the paths from 23 surface drifters crossing a major fairway in the western and c...

Marine protected areas have been widely touted as both as an insurance policy against fishery management failures and as an integral part of an optimal management strategy for some fisheries. However, incorrectly sized or located MPAs may actually increase the risk of depletion or collapse of some species, and can easily reduce the sustainable value of the system of fisheries they impact. Furth...

SUMMARY There have been many matching pursuit algorithms (MPAs) which handle the sparse signal recovery problem, called compressed sensing (CS). In the MPAs, the correlation step makes a dominant computational complexity. In this paper, we propose a new fast correlation method for the MPA when we use partial Fourier sensing matrices and partial Hadamard sensing matrices which are widely used as...
