Download or read book Northern Elephant Seal Monitoring (Mirounga Angustirostris) at Point Reyes National Seashore 2008-2009 Breeding Seasons written by Sarah Allen and published by CreateSpace. This book was released on 2013-08-06 with total page 38 pages. Available in PDF, EPUB and Kindle. Book excerpt: Northern elephant seals (Mirounga angustirostris) established a breeding population at Point Reyes National Seashore (PORE) in 1981 and since then the colony has grown steadily (Allen et al. 1989). Currently, elephant seals breed at numerous sites within PORE, with four primary sites located at Drake's Beach (DB), Point Reyes Headland (PRH), South Beach (SB), and Chimney Rock Loop (CRL). PORE began to monitor the elephant seal population to contribute to the understanding of population changes and management needs, and to develop research, interpretation and enforcement strategies. A pinniped monitoring protocol was developed in 2009 and includes objectives for monitoring elephant seals to determine trends population growth and productivity.

Book Synopsis A Coast to Explore by : Miles O. Hayes
Download or read book A Coast to Explore written by Miles O. Hayes and published by Pandion Books. This book was released on 2010-12-01 with total page 354 pages. Available in PDF, EPUB and Kindle. Book excerpt: From wave-cut rock cliffs and sea caves to gravel beaches and coastal dunes, California’s coastline has enthralled visitors from around the world. A Coast to Explore describes the origins of these coastal features and unravels the wonderful mystery of how the birth of the San Andreas Fault system created what we see today. Miles O. Hayes and Jacqueline Michel have been mapping the coast of California since the 1980s as part of a larger initiative to protect coastlines around the world from hazardous oil spills. A Coast to Explore is the culmination of their work. Through a delightful narrative, it details the geological evolution of central California’s coast from Bodega Bay to Point Conception, including the effects of erosion during El Niños, the impacts of tsunamis, and the formation of spectacular raised marine terraces. Key ecological resources are described for each of the major subdivisions of the coast. Through richly illustrated diagrams, full-color photographs, and satellite images, A Coast to Explore takes readers on a fascinating journey of discovery so they can better understand why the Central California coast is so remarkable.

Book Synopsis Best Practice Guidelines for Great Ape Tourism by : Elizabeth J. Macfie
Download or read book Best Practice Guidelines for Great Ape Tourism written by Elizabeth J. Macfie and published by IUCN. This book was released on 2010 with total page 87 pages. Available in PDF, EPUB and Kindle. Book excerpt: Executive summary: Tourism is often proposed 1) as a strategy to fund conservation efforts to protect great apes and their habitats, 2) as a way for local communities to participate in, and benefit from, conservation activities on behalf of great apes, or 3) as a business. A few very successful sites point to the considerable potential of conservation-based great ape tourism, but it will not be possible to replicate this success everywhere. The number of significant risks to great apes that can arise from tourism reqire a cautious approach. If great ape tourism is not based on sound conservation principles right from the start, the odds are that economic objectives will take precedence, the consequences of which in all likelihood would be damaging to the well-being and eventual survival of the apes, and detrimental to the continued preservation of their habitat. All great ape species and subspecies are classified as Endangered or Critically Endangered on the IUCN Red List of Threatened Species (IUCN 2010), therefore it is imperative that great ape tourism adhere to the best practice guidelines in this document. The guiding principles of best practice in great ape tourism are: Tourism is not a panacea for great ape conservation or revenue generation; Tourism can enhance long-term support for the conservation of great apes and their habitat; Conservation comes first--it must be the primary goal at any great ape site and tourism can be a tool to help fund it; Great ape tourism should only be developed if the anticipated conservation benefits, as identified in impact studies, significantly outweigh the risks; Enhanced conservation investment and action at great ape tourism sites must be sustained in perpetuity; Great ape tourism management must be based on sound and objective science; Benefits and profit for communities adjacent to great ape habitat should be maximised; Profit to private sector partners and others who earn income associated with tourism is also important, but should not be the driving force for great ape tourism development or expansion; Comprehensive understanding of potential impacts must guide tourism development. positive impacts from tourism must be maximised and negative impacts must be avoided or, if inevitable, better understood and mitigated. The ultimate success or failure of great ape tourism can lie in variables that may not be obvious to policymakers who base their decisions primarily on earning revenue for struggling conservation programmes. However, a number of biological, geographical, economic and global factors can affect a site so as to render ape tourism ill-advised or unsustainable. This can be due, for example, to the failure of the tourism market for a particular site to provide revenue sufficient to cover the development and operating costs, or it can result from failure to protect the target great apes from the large number of significant negative aspects inherent in tourism. Either of these failures will have serious consequences for the great ape population. Once apes are habituated to human observers, they are at increased risk from poaching and other forms of conflict with humans. They must be protected in perpetuity even if tourism fails or ceases for any reason. Great ape tourism should not be developed without conducting critical feasibility analyses to ensure there is sufficient potential for success. Strict attention must be paid to the design of the enterprise, its implementation and continual management capacity in a manner that avoids, or at least minimises, the negative impacts of tourism on local communities and on the apes themselves. Monitoring programmes to track costs and impacts, as well as benefits, [is] essential to inform management on how to optimise tourism for conservation benefits. These guidelines have been developed for both existing and potential great ape tourism sites that wish to improve the degree to which their programme constributes to the conservation rather than the exploitation of great apes.

Book Synopsis Mammals and Birds as Bioindicators of Trace Element Contaminations in Terrestrial Environments by : Elżbieta Kalisińska
Download or read book Mammals and Birds as Bioindicators of Trace Element Contaminations in Terrestrial Environments written by Elżbieta Kalisińska and published by Springer. This book was released on 2019-03-01 with total page 708 pages. Available in PDF, EPUB and Kindle. Book excerpt: The population explosion that began in the 1960s has been accompanied by a decrease in the quality of the natural environment, e.g. pollution of the air, water and soil with essential and toxic trace elements. Numerous poisonings of people and animals with highly toxic anthropogenic Hg and Cd in the 20th century prompted the creation of the abiotic environment, mainly in developed countries. However, the system is insufficient for long-term exposure to low concentrations of various substances that are mainly ingested through food and water. This problem could be addressed by the monitoring of sentinels – organisms that accumulate trace elements and as such reflect the rate and degree of environmental pollution. Usually these are long-lived vertebrates – herbivorous, omnivorous and carnivorous birds and mammals, especially game species. This book describes the responses of the sentinels most commonly used in ecotoxicological studies to 17 trace elements.
