Conservation Strategies for a Changing Climate

by Weronika Konwent

     Conservation of marine species, especially as a response to climate change, requires a reliable conception of current and future spatial distribution of species to allow for the protection of biodiversity and the establishment of conservation at the most appropriate sites. Gormley et al. use Species Distribution Modeling (SDM) to predict how Priority Marine Habitats (PMH) in the NE Atlantic might shift and change according to climate change induced changes.

A Strategy for Response to Climate Change in Marine Conservation

by Weronika Konwent

     An effect of global warming is an increase in sea-surface temperatures (SST), which impacts the distribution and range of corals. As temperatures increase, coral distribution will shift poleward. This is problematic because current marine protected areas do not take into account the distribution effects of climate change. Continual shifting of MPAs as conditions worsen is more than likely to meet political and logistical roadblocks. Makino et al (2014) established an integrative system by which to determine priority selection of habitats for MPAs. This research aims to create a process through which climate change can be factored into subsequent MPA planning, and will cater to coral distribution trends not only now but in the future as well.

Partial Protection in Mexican MPA Only Marginally Effective in Restoring Reef Ecosystem

by Katie Huang

Loreto Bay National Park (LBNP) is a marine protected area (MPA) in the Gulf of California, Mexico, which bans fishing in some areas and allows limited amounts in others. However, since only a small region of the MPA is completely protected, it is possible that the benefits of a no-take area do not offset the effects of the permitted fishing. From 1998 to 2010, Rife et al. (2013) surveyed the biomasses of fish in sites within the LBNP and in open control areas and compared the data from before and after the MPA was established. They found that the biomasses of protected and open area fish were not significantly different. Although the biomasses of herbivorous and zooplanktivorous fish increased significantly within the MPA’s restricted area, the authors did not observe changes in apex predator and carnivore biomasses which suggests that the reef ecosystem is still unhealthy even after 13 years of protection. Possible explanations include poor enforcement of regulations as well as the small size of the restricted area, and management solutions should address these issues to make the LBNP more effective.
