This book was released on 2015 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 1981, Leatherback Sea Turtle populations in Canadian waters were assessed by the Committee on the Status of Endangered Wildlife in Canada (COSEWIC) as Endangered. This status was confirmed in 2001, and in 2003, the Leatherback Sea Turtle was listed as Endangered on Schedule 1 of the Species at Risk Act (SARA). In May 2012, the species was reassessed as two separate populations (Atlantic and Pacific). Both populations continue to be designated as Endangered. As part of the SARA recovery process, the?Recovery Strategy for the Leatherback Turtle populations in Pacific Canadian waters? was published on the SARA Registry in February 2007. For species listed as Threatened or Endangered, SARA requires identification of the habitat necessary for the survival or recovery of a listed wildlife species. Once this habitat is identified in the final recovery strategy or action plan, it is deemed the species??critical habitat? and afforded legal protection from destruction under the Act. Leatherback Sea Turtles feed on scyphozoan prey in temperate high latitude locales, such as the Canadian Pacific coast. An envelope model was used to locate suitable habitat for Leatherback Sea Turtle foraging, and describe the biophysical function and features of suitable habitat in Canadian Pacific waters.

This book was released on 2012-08-15 with total page 170 pages. Available in PDF, EPUB and Kindle. Book excerpt: The leatherback sea turtle (Dermochelys coriacea; leatherback) is the largest and most migratory of the world's turtles, with the most extensive geographic range of any living reptile. This highly specialized turtle is the only living member of the family Dermochelyidae. It exhibits reduced external keratinous structures: scales are temporary, disappearing within the first few months and leaving the entire body covered by smooth black skin. Dorsal keels streamline a tapered form. The species has a shallow genealogy and strong population structure worldwide, supporting a natal homing hypothesis. Gravid females arrive seasonally at preferred nesting grounds in tropical and subtropical latitudes, with the largest colonies concentrated in the southern Caribbean region and central West Africa. Non-breeding adults and sub-adults journey into temperate and subarctic zones seeking oceanic jellyfish and other soft-bodied invertebrates. Long-distance movements are not random in timing or location, with turtles potentially possessing an innate awareness of profitable foraging opportunities. The basis for high seas orientation and navigation is poorly understood. Studies of metabolic rate demonstrate marked differences between leatherbacks and other sea turtles: the “marathon” strategy of leatherbacks is characterized by relatively lower sustained active metabolic rates. Metabolic rates during terrestrial activities are well-studied compared with metabolic rates associated with activity at sea. The species faces two major thermoregulatory challenges: maintaining a high core temperature in cold waters of high latitudes and/or great depths, and avoiding overheating in some waters and latitudes, especially while on land during nesting. The primary means of physiological osmoregulation are the lachrymal glands, which eliminate excess salt from the body. The leatherback was re-classified in 2000 by the International Union for the Conservation of Nature (IUCN) Red List of Threatened Species as Critically Endangered. It remains vulnerable to a wide range of threats, including bycatch, ingestion of and entanglement in marine debris, take of turtles and eggs, and loss of nesting habitat to coastal processes and beachfront development. There is no evidence of significant current declines at the largest of the Western Atlantic nesting grounds, but Eastern Atlantic populations face serious threats and Pacific populations have been decimated. Incidental mortality in fisheries, implicated in the collapse of the Eastern Pacific population, is a largely unaddressed problem worldwide. Although sea turtles were among the first marine species to benefit from legal protection and concerted conservation effort around the world, management of contemporary threats often falls short of what is necessary to prevent further population declines and ensure the species' survival throughout its range. Successes include regional agreements that emphasize unified management approaches, national legislation that protects large juveniles and breeding-age adults, and community-based conservation efforts that offer viable alternatives to unsustainable patterns of exploitation. Future priorities should include the identification of critical habitat and priority conservation areas, including corridors that span multiple national jurisdictions and the high seas, the creation of marine management regimes at ecologically relevant scales and the forging of new governance patterns, reducing or eliminating causal factors in population declines (e.g., over-exploitation, bycatch), and improving management capacity at all levels.

Book excerpt: The Law Library presents the complete text of the Endangered and Threatened Species - Critical Habitat Designation for Endangered Leatherback Sea Turtle (US National Oceanic and Atmospheric Administration Regulation) (NOAA) (2018 Edition). Updated as of May 29, 2018 We, the National Marine Fisheries Service (NMFS), issue a final rule to revise the current critical habitat for the leatherback sea turtle (Dermochelys coriacea) by designating additional areas within the Pacific Ocean. This designation includes approximately 16,910 square miles (43,798 square km) stretching along the California coast from Point Arena to Point Arguello east of the 3,000 meter depth contour; and 25,004 square miles (64,760 square km) stretching from Cape Flattery, Washington to Cape Blanco, Oregon east of the 2,000 meter depth contour. The designated areas comprise approximately 41,914 square miles (108,558 square km) of marine habitat and include waters from the ocean surface down to a maximum depth of 262 feet (80 m). Other Pacific waters within the U.S. Exclusive Economic Zone (EEZ) were evaluated based on the geographical area occupied by the species, but we determined that they were not eligible for designation, as they do not contain the feature identified as essential to the conservation of the species. The total estimated annualized economic impact associated with this designation is estimated to range between $188,000 and $9.1 million U.S. dollars.

This book was released on 2014 with total page 8 pages. Available in PDF, EPUB and Kindle. Book excerpt: "This document provides information for the identification of critical habitat for Leatherback Sea Turtles to the extent possible based on best available information. A key distinguishing characteristic of critical habitat (as defined by The Species at Risk Act or SARA) is that critical habitat is the component of habitat 'necessary' for survival or recovery of the species. The critical habitat identification process is an inherently iterative approach that is only complete when the recovery goal(s) is/are achieved."--Document.

Book excerpt: "The Leatherback Sea Turtle (Dermochelys coriacea) was listed as Endangered under the Species at Risk Act (SARA) in 2003. This action plan is considered one in a series of documents that are linked and should be taken into consideration together, including the Committee on the Status of Endangered Wildlife in Canada (COSEWIC) status report, the recovery strategy, and the progress report on the recovery strategy. This document is considered a partial action plan because current best available information is insufficient to identify critical habitat (DFO 2014). Identification of the habitat necessary to support survival and recovery of the species may be addressed in an amendment to the recovery strategy at a later date"--Executive summary, page ii.

Book excerpt: The most comprehensive book ever written on leatherback sea turtles. Weighing as much as 2,000 pounds and reaching lengths of over seven feet, leatherback turtles are the world’s largest reptile. These unusual sea turtles have a thick, pliable shell that helps them to withstand great depths—they can swim more than one thousand meters below the surface in search of food. And what food source sustains these goliaths? Their diet consists almost exclusively of jellyfish, a meal they crisscross the oceans to find. Leatherbacks have been declining in recent decades, and some predict they will be gone by the end of this century. Why? Because of two primary factors: human redevelopment of nesting beaches and commercial fishing. There are only twenty-nine index beaches in the world where these turtles nest, and there is immense pressure to develop most of them into homes or resorts. At the same time, longline and gill net fisheries continue to overwhelm waters frequented by leatherbacks. In The Leatherback Turtle, James R. Spotila and Pilar Santidrián Tomillo bring together the world’s leading experts to produce a volume that reveals the biology of the leatherback while putting a spotlight on the conservation problems and solutions related to the species. The book leaves us with options: embark on the conservation strategy laid out within its pages and save one of nature’s most splendid creations, or watch yet another magnificent species disappear.
