Preserving a 300,000 foursquare km surface area inwards Patagonian waters could ameliorate the conservation of xx % of the population of sea birds inwards their natural habitat, according to a study published inwards the mag Conservation Biology as well as led past times the adept Francisco Ramírez, researcher from the Faculty of Biology as well as the Biodiversity Research Institute of the University of Barcelona (IRBio).

One of the marine ecosystems alongside to a greater extent than biodiversity worldwide
Only iii % of the bounding main surface is protected, which is a lower marking to the 1 inwards terrestrial ecosystems. Marine ecosystems inwards the Argentinian Patagonia are 1 of the areas alongside a larger biodiversity as well as highest biological production worldwide. Despite their ecological value, they are at in 1 lawsuit 1 of the most threatened marine areas past times the touching on of human activeness -intense angling activity- as well as changes related to global warming.
At the moment, seabirds are the most threatened plane grouping worldwide. As business office of this research, experts studied the populations of 14 species of seabirds distributed over 3,000 kilometres inwards the Patagonian coast. Among the most threatened seabirds are the Olrog's Gull (Larus atlanticus), the red-legged cormorant (Phalacrocorax gaimardi) as well as the Magellanic penguin (Spheniscus magellanicus), according to the recent reports past times the International Union for Conservation of Nature (IUCN).
Environmental conservation: oceanic dynamics matter
In general, the delimitation inwards protected marine areas is based on the experts' criteria on the textile as well as information of the distribution of some species which are peculiarly threatened. The novel study opens a novel persuasion to position primal areas for the conservation of seabirds inwards 1 of the most emblematic as well as productive natural systems of the world.
According to Francisco Ramírez, from the Department of Evolutionary Biology, Ecology as well as Environmental Sciences of the UB as well as IRBio, "in our study, nosotros carried out a modelling of the spatial distribution of to a greater extent than than 2 1000000 seabirds of 14 dissimilar species. With these data, nosotros identified the areas that let us to protect at to the lowest degree a xx % of these populations through the application of preservation measures".
This is 1 of the start studies to catch the upshot of bounding main currents inwards the planning of preserved marine areas. According to Isabel Afán, "if nosotros catch the marine electrical current organization of the area, at that topographic point are other areas that are connected to the priority areas to locomote protected which are also of import regarding management, since they tin choose environs alterations to the priority areas. For instance, inwards accident cases such equally bounding main dumpings, it is of import to know the areas that could choose the run a peril products to protected areas, as well as therefore, utilize some administration mensurate on these areas".
The novel study to delimit protection areas inwards Patagonian regions takes into concern human relationship the protected marine regions that were proposed past times BirdLife International, as well as based on the spatial distribution of pelagic seabirds. However, these species nest exterior the Patagonian coasts as well as see the marine regions to larn food, experts warn. Therefore, apart from including BirdLife's suggestions, the novel study adds a ready of coastal areas to ameliorate the conservation of 14 species that breed to a greater extent than or less the Patagonian coasts.
Protecting oceans for a to a greater extent than sustainable future
People are to a greater extent than as well as to a greater extent than aware -thanks to international organisms- of the postulate to notice a residue betwixt environmental protection inwards the oceans as well as high socioeconomic touching on activities (fisheries, leisure activities, etc.). The methodology that was published inwards Conservation Biology could locomote applied to marine ecosystems where researchers know close the spatial distribution of breeding colonies of seabirds as well as the sum of individuals per colony.
Since the marine environs is a broad as well as dynamic scenario, as well as difficult to access, "it is necessary to review the suggested protected marine areas to ameliorate environmental administration tools. Therefore, this is a dynamic as well as adaptive procedure which should count on all the involved stakeholders, from fishermen to conservationist entities", concludes the researcher Francisco Ramírez.
