Trade-off analysis for marine protected area management
This paper outlines an approach to natural resource management that incorporates multiple objectives for protected area management within a decision-making framework. Both regulators and other major stakeholders are directly incorporated into the approach to enhance decision-making processes. We call this approach trade-off analysis. The approach uses a framework based on multi-criteria analysi...
متن کاملStepwise strategic environmental management in marine protected area
In recent decades, necessity to protect environment has been a serious concern for all people and international communities. In appropriate development of human economic activities, subsistence dependence of the growing world population on nature decreases the natural diversity of ecosystems and habitats day by day and provides additional constraints for life and survival of wildlife. As a resu...
متن کاملHearing measurements from a stranded infant Risso's dolphin, Grampus griseus.
An infant Risso's dolphin (Grampus griseus) was rescued from the beach in Southern Portugal, and an audiogram was measured using auditory evoked potentials (AEP) and envelope following response (EFR) techniques for frequencies from 4 to 150 kHz. The stimuli used were custom sinusoidally amplitude-modulated (SAM) tone-bursts, and the AEP responses were collected, averaged and analyzed to quantif...
متن کاملMixed-species associations of striped dolphins (Stenella coeruleoalba), short-beaked common dolphins (Delphinus delphis), and Risso’s dolphins (Grampus griseus) in the Gulf of Corinth (Greece, Mediterranean Sea)
Surveys to assess cetacean presence were conducted in July 1995 and 1997 in the Gulf of Corinth, which is an almost-enclosed sea in Greece, Eastern Mediterranean. The dolphin sighting frequencies were high (0.043 sightings/km). Four dolphin species were encountered: striped dolphins (Stenella coeruleoalba), short-beaked common dolphins (Delphinus delphis), Risso’s dolphins (Grampus griseus) and...
متن کاملMolecular Evidence of a Captive-Born Intergeneric Hybridization Between Bottlenose and Risso’s Dolphins: Tursiops truncatus × Grampus griseus
Natural hybridization occurs rarely in mammals, but it is thought to have the potential to produce viable hybrid offspring in cetaceans more easily than in other mammals. Among cases of cetacean hybridization, hybrids between bottlenose dolphins (Tursiops truncatus) and Risso’s dolphins (Grampus griseus) have been documented in both the wild and in captivity. However, until now, no molecular ev...
