The Mediterranean monk seal M onachus monachus : status, biology, threats, and conservation priorities (original) (raw)
Related papers
Over the last few decades a dramatic decline in the number of Mediterranean monk seals (Monachus monachus) limited scientific studies on the biology, behaviour, and ecology of the species. This lack of information impaired the effectiveness of conservation strategies. Thus, any further information gathered on the monk seal has utmost value in the work to halt and reverse the plight of the species. A hitherto unknown Cilician Basin colony of the Mediterranean monk seal has been investigated during a 6-year period between 1995 and 2001. Results of direct in-cave surveys and land based seal-watch observations enabled the evaluation of habitat use and preliminary demographic information. A total of 39 caves were discovered among which only three were used for breeding. Scarcity of the breeding caves emphasised the importance of breeding habitat in the survival of the colony. Common features of the breeding caves are found as an entrance with a protective barrier against strong waves; a chamber with a wide beach; and a wellsheltered shallow pool. Supplementary data obtained from infrared monitors installed in three actively used caves were used to assess the number of individuals. Throughout the study period, 25 individuals were identified and 11 newborn pups were found. Evaluation of the results suggests the presence of sub-regions inhabited by an individually identified sub-group of monk seals. Recommendations for conservation guided by this information is a Marine Protected Area consisting of two zones; a restricted core zone prohibiting any human activity securing breeding habitat and a restricted fishery zone securing sustainability of the food source. #
Ecological changes in the Kizilliman Marine Protected Area which was designated for the conservation of Mediterranean monk seal have been evaluated. The major parameters taken into consideration are i) the size distribution of the key trawl species, ii) changes in the daily catch records of the local artisanal fishermen, iii) Inside / outside MPA comparison of the diversity of fish in the near shore rocky habitats, and iv) annual breeding rate of the monk seal:

The Mediterranean monk seal is categorized as Critically Endangered on the IUCN Red List and is in urgent need of effective conservation measures. Following a steep decline in the 20th century, the National Park Service of Madeira initiated efforts to protect the species in the archipelago of Madeira, including habitat protection, scientific research and public awareness. The aim of this study was to analyse data collected during a monitoring project (1988À2005) to assess the conservation status of the species and identify priority conservation actions for the future. The study recorded the presence of the species at key pupping sites in a strictly protected area at the Desertas Islands, increased sightings in recent years around the main island of Madeira, an increase in the number of pups born, and low mortality. The population in the archipelago of Madeira is currently estimated to be 20-30 adults. These findings suggest that the species remains Critically Endangered in the area but that its conservation situation has improved because of the implementation of effective conservation actions. Conservation priorities identified include protecting suitable monk seal habitat at Madeira, investigating sealÀfisheries interactions, increasing environmental education, and strengthening regional legislation for the protection of the species.

Once widespread throughout the Black and Mediterranean Seas and the coasts of north Africa, the Endangered Mediterranean monk seal Monachus monachus has disappeared throughout most of its original range. In Cyprus evidence suggests that the species became effectively extinct at the end of the th century. Following an increase of seal sightings around the island, a monitoring programme was established in to evaluate the status of the species. During -, using field surveys, photographs from camera traps and an information network, we recorded an increasing number of seal sightings, and the birth of several pups, indicating the permanent presence of the species on the island. This is the first recorded reestablishment of a Mediterranean monk seal population in an area of its former range following near eradication.

In Cyprus evidence suggests that the species became effectively extinct at the end of the 20th century. Following an increase of seal sightings around the island, a monitoring programme was established in 2009 to evaluate the status of the species. During 2009–2018, using field surveys, photographs from camera traps and an information network, we recorded an increasing number of seal sightings, and the birth of several pups, indicating the permanent presence of the species on the island.

The Mediterranean monk seal gives birth almost exclusively in coastal caves. Given its critical conservation status, the identification and protection of such sites is important for the survival of the species. From 1990 to 2004 we collected data on physical and environmental ...
