Marine protected area (MPA) designs are likely to require iterative refinement as new knowledge is gained. In particular, there is an increasing need to consider the effects of climate change, especially the ability of ecosystems to resist and/or recover from climate-related disturbances, within the MPA planning process. However, there has been limited research addressing the incorporation of c...

Many governments have recently gone on record promising large-scale expansions of protected areas to meet global commitments such as the Convention on Biological Diversity. As systems of protected areas are expanded to be more comprehensive, they are more likely to be implemented if planners have realistic budget estimates so that appropriate funding can be requested. Estimating financial budge...

Abstract Context Habitat connectivity is key when designing reserve networks for conservation of species at risk. Acquiring land over time to achieve multiple in a systematic plan can pose challenge because not all high priority parcels will be acquired, occurrence data often limited, and using models together complex. Objectives We evaluated four possible acquisition strategies such their abil...

Concerns over worldwide declines in marine resources have prompted the search for innovative solutions for their conservation and management, particularly for coral reef ecosystems. Rapid advances in sensor resolution, coupled with image analysis techniques tailored to the unique optical problems of marine environments have enabled the derivation of detailed benthic habitat maps of coral reef h...

Protected areas (PAs) are often considered the most important biodiversity conservation areas in national plans, but PAs often do not represent national-scale biodiversity. We evaluate the current conservation status of plant biodiversity within current existing PAs, and identify potential additional PAs for South Korea. We modeled species ranges for 2,297 plant species using Multivariate Adapt...

برای حفاظت از تنوع زیستگاه‏ها و جمعیت‏های حیات ‏وحش باید به انتخاب مناطق معرف و نمونه از کل طبیعت پرداخت. هدف اصلی این پژوهش انتخاب مناسب‏ترین شبکة مناطق تحت حفاظت در استان مازندران است. به این منظور، زیستگاه بالقوه 8 گونه پستاندار، مناطق مناسب پراکنش 4 گروه پرنده و 26 تیپ پوشش جنگل به عنوان معیارهای انتخاب مناطق تحت حفاظت استفاده شدند. اولویت‏بندی توسط الگوریتم مذاب‏سازی شبیه‏سازی ‏شده تحت نرم...
