APPENDIX: Habitat and population viability analysis (PHVA 2001)…………………….. …....89 3 SUMMARY The Mediterranean monk seal ( Monachus monachus Hermann, 1779) is one of the most threatened mammals in the world. According to the IUCN, there may be less than 500 seals remaining in the Mediterranean and along the Eastern Atlantic coastline. It has disappeared from most of its distribution range, except for a few isolated groups. The low numbers and negative trends are a cause for concern, even based on the most optimistic estimates. There are two breeding colonies of Mediterranean monk seal in the Eastern Atlantic: one on the Desertas Islands (Madeira) and the other on the Cabo Blanco Peninsula (Morocco-Mauritania). Since the colonies are probably isolated demographically and genetically (with less than 200 seals each concentrated along a few kilometres of coastline), experts regard its status in the Atlantic as very critical. The alarming decline of seals at Cabo Blanco in 1997 increased international concern, to the point that the most important nature conservation bodies urge prompt and effective action. The monk seal populations in the Mediterranean area have been the focus of attention since 1986 (UNEP/MAP 1987). Efforts have centred on implementing the Monk Seal Management Plan (an international strategy), within the framework of the Action Plan for the Mediterranean (Barcelona Convention 1976). Important initiatives and projects have been developed in the Atlantic that are cause for a renewed optimism with regards to monk seal conservation. These include the setting up of the Desertas Islands Nature Reserve in Madeira and the Fisheries Protected Area in the Moroccan waters of Cabo Blanco peninsula. However, there is still a need for a coordinated international strategy and a regional action plan for the monk seal in the Atlantic area. This document contains an Action Plan based on strong international collaboration to recover the Atlantic populations of monk seal and guarantee its continuity as a self-sustaining part of the ecosystem. The Plan reflects international concern about the critical status of the Mediterranean monk seal and the responsibility of Morocco, Spain, Mauritania and Portugal (the four countries in its distribution range in the Atlantic, in the framework of the Bonn Convention), to promote and undertake concerted and effective actions to reverse its decline and recover the species. The threats that have been identified to date and which are reflected in the document range from massive die-offs due to red tides, diseases and sub-optimal pupping sites to interactions with fisheries and habitat disturbance. The Plan seeks to encourage the states involved to implement a series of measures to maintain or re-establish favourable conservation status, the seal’s natural habitat and the seal populations in the region. The main action is the creation of a Network of Special Areas of Conservation for the Monk

  • Exploitation of Fur Seals and Sea Lions from Australian, New Zealand and Adjacent Subantarctic Islands During the Eighteenth, Nineteenth and Twentieth Centuries
    Exploitation of fur seals and sea lions from Australian, New Zealand and adjacent subantarctic islands during the eighteenth, nineteenth and twentieth centuries John K. Ling P.O. Box 271, Clare, South Australia 5459 ABSTRACT Details of skin cargoes of fur seal Arctocephalus spp. and sea lion Neophoca cinerea and Phocarctos hookeri, originating from southern Australia, New Zealand and the adjacent subantarctic islands in the lath, 19th and 20th centuries have been collated from several secondary historicsl sources. These sources quoted quantities of skins in terms of actual tallied numbers, as untallied "cargoes" or as casks, sacks or bundles. Untallied cargoes were Downloaded from http://meridian.allenpress.com/australian-zoologist/article-pdf/31/2/323/1473420/az_1999_036.pdf by guest on 30 September 2021 converted into numbers by averaging tallied cargoes; and casks, sacks and bundles were arbitrarily deemed to contain 40, 20 and 5 skins respectively. Annual and total yields of skins are presented for ten separate areas in the region: Bass Strait, King Island, Kangaroo Island. Western Australia, New Zealand, Bounty Islands, Auckland Islands, Antipodes Islands. Campbell Island and Macquarie island. At least 1 367 000 fur seal skins were harvested between 1792 and 1948149 in the whole of the Australasian region. More than 1309 000 skins - 96% of the total - were taken up to 1830. Records indicate that only about 4 100 Neophoca and 5 800 Phocarctos were obtained from their respective areas. These figures must be regarded as minimal, as it is likely thatmany cargoes were obtained by English, American and French vessels and shipped directly to European or Asian markets.

OTARIIDAE AND PHOCIDAE DEFINITION AND GENERAL DESCRIPTION Pinnipeds are aquatic carnivores. They differ from other mammals in their streamlined shape, reduction of pinnae and adaptation of both fore and hind feet to form flippers. In the skull, the orbits are enlarged, the lacrimal bones are absent or indistinct and there are never more than three upper and two lower incisors. The cheek teeth are nearly homodont and some conditions of the ear that are very distinctive (Repenning 1972). Both superfamilies of pinnipeds, Phocoidea and Otarioidea, are represented in Australian waters by a number of species (Table 56.1). The various superfamilies and families may be distinguished by important and/or easily observed characters (Table 56.2). King (1983b) provided more detailed lists and references. These and other differences between the above two groups are not regarded as being of great significance, especially as an undoubted fur seal (Australian Fur-seal Arctocephalus pusillus) is as big as some of the sea lions and has some characters of the skull, teeth and behaviour which are rather more like sea lions (Repenning, Peterson & Hubbs 1971; Warneke & Shaughnessy 1985). The Phocoidea includes the single Family Phocidae – the ‘true seals’, distinguished from the Otariidae by the absence of a pinna and by the position of the hind flippers (Fig.

The auditory biology of monk seals is compelling from behavioral, evolutionary, and conservation perspectives, but we presently lack substantive bioacoustic infor- mation for this species, with no formal descriptions of underwater vocalizations and limited data concerning hearing. These seals have been isolated for more than 10 million yr and have auditory structures differing from those of related species. Additionally, unlike other aquatically mating phocids, monk seals breed asynchronously and are not known to produce social calls in water. To address existing knowledge gaps, we trained a mature male Hawaiian monk seal to perform a psychophysical task while submerged. Detection thresholds were measured for narrowband sounds across the frequency range of hearing. We also conducted a year-round characterization of the seal’s spontaneous underwater vocalizations. This individual demonstrated best hearing between 0.2 and 33 kHz, with a lower high-frequency roll-off than that of related species.

All material known to us as of February 10, 1978, which deals either exclusively or in part with Monachus schauinsl.andi, has been included. A special feature of the bibliography is the incorporation of references to articles from the " Honolulu newspapers and to unpublished reports, which we were in a strategic position to locate. It should be noted that an unknown number of publications also exist on the Mediterranean monk seal (Monachus monachus) , as well as the Caribbean monk seal (Monachus tY'opical.is) which is now thought to be extinct.

Canine teeth collected during the last 2 decades from 45 dead monk seals inhabiting Greek waters were processed for age estimation. Ages were best estimated by counting growth layer groups (GLGs) in the cementum adjacent to the root tip using un - processed longitudinal or transverse sections (360 µm thickness) observed under polarized light. Decalcified and stained thin sections (8 to 23 µm) of both cementum and dentine were inferior to unprocessed sections. From analysing patterns of deposition in the cementum of known age- maturity class individuals, one GLG was found to be deposited annually in M.

  • Letter to K. Baker, 1-29-07
    Marine Mammal Commission 4340 East-West Highway, Room 905 Bethesda, MD 20814 29January 2007 Mr. Kyle Baker National Marine Fisheries Service 263 13th Avenue, South St. Petersburg, FL 33701 Dear Mr. Baker: The Marine Mammal Commission, in consultation with its Committee of Scientific Advisors on Marine Mammals, has reviewed the National Marine Fisheries Service’s 29 November 2006 Federal Register notice announcing its intent to conduct a review of the Caribbean monk seal, Monachus tropicalis, under the Endangered Species Act and requesting information on the species’ status. We have reviewed our files and, with great regret, we have concluded that the species is extinct and should be removed from the list of endangered and threatened species. Fossil and archeological evidence, along with sighting records, indicate that the species once occurred from the southeastern United States through the Bahamas and the Caribbean Sea. A review of those records by Rice (1973) concluded that the last authoritative sighting was of a small colony of animals at Seranilla Banks between Jamaica and the Yucatan Peninsula in 1952. A few other unconfirmed sightings were reported from the 1950s into the 1970s, but at least some of those were reported to involve escaped California sea lions (Gunter 1968 cited in Rice 1973). Although the species may have been extinct when the Endangered Species Act was passed in 1973, the Marine Mammal Commission wrote to the National Marine Fisheries Service on 26 January 1977 recommending that the Caribbean monk seal be listed as “endangered” under the Endangered Species Act and “depleted” under the Marine Mammal Protection Act.
