Available in PDF, EPUB and Kindle. Book excerpt: This advanced text focuses on the uses of distance sampling to estimate the density and abundance of biological populations. It addresses new methodologies, new technologies and recent developments in statistical theory and is the follow up companion to Introduction to Distance Sampling (OUP, 2001). In this text, a general theoretical basis is established for methods of estimating animal abundance from sightings surveys, and a wide range of approaches to analysis of sightings data is explored. These approaches include: modelling animal detectability as a function of covariates, where the effects of habitat, observer, weather, etc. on detectability can be assessed; estimating animal density as a function of location, allowing for example animal density to be related to habitat and other locational covariates; estimating change over time in populations, a necessary aspect of any monitoring programme; estimation when detection of animals on the line or at the point is uncertain, as often occurs for marine populations, or when the survey region has dense cover; survey design and automated design algorithms, allowing rapid generation of sound survey designs using geographic information systems; adaptive distance sampling methods, which concentrate survey effort in areas of high animal density; passive distance sampling methods, which extend the application of distance sampling to species that cannot be readily detected in sightings surveys, but can be trapped; and testing of methods by simulation, so that performance of the approach in varying circumstances can be assessed.

Download or read book Cetacean Abundance in the California Current Estimated from a 2008 Ship based Line transect Survey written by Jay Barlow and published by . This book was released on 2010 with total page 19 pages. Available in PDF, EPUB and Kindle. Book excerpt: The abundance of most cetaceans along the US West Coast was estimated from data collected on a 2008 ship-based survey. Line-transect methods were used on the survey, and analyses were based on the multiple-covariate line-transect approach used by Barlow and Forney (2007) in their analysis of previous West Coast Surveys. Shortbeaked common dolphins, long-beaked common dolphins and Dall's porpoises were the most abundant small cetaceans with abundances of ~370,000, ~62,000 and ~30,000 (respectively). Fin whales and humpback whales were the most abundant large whales, with abundances of ~3,000 and ~1,000 (respectively). In total, abundances were estimated for 17 cetacean species plus several categories of cetaceans that could not be identified to species.

This book was released on 2024-05-24 with total page 342 pages. Available in PDF, EPUB and Kindle. Book excerpt: The ocean is under increasing threat from the expansion of human activities. The combined impacts of these threats as well as the potential impacts of climate change and ocean acidification have placed thousands of species at risk of extinction, and have impaired the structure, function, productivity and resilience of marine ecosystems. Currently, some parts of the world's oceans are significantly impacted, yet are without any form of effective management. Only a small proportion of the oceans are within protected area systems. Globally, measures are being taken to increase protection and sustainable management, but application is uncoordinated and not always effective. In order to support effective policy action by countries and competent international and regional organizations, it is critical to build a sound understanding of the most ecologically and biologically important ocean areas that support healthy marine ecosystems so that the necessary steps to ensure the long-term function and resilience of these systems can be taken.
