Report on the Progress of Recovery Strategy Implementation for the North Atlantic Right Whale (Eubalaena Glacialis) in Canadian Waters for the Period 2009-2014


Book Description

"This Progress Report describes the progress made from 2009 to 2014 toward meeting the recovery objectives listed in the Recovery Strategy for the North Atlantic Right Whale (Eubalaena glacialis) in Canadian Waters (hereafter "Recovery Strategy). This report is one in a series of documents for this species that are linked and should be considered together, including a recovery potential assessment (DFO 2007), the Committee on the Status of Endangered Wildlife in Canada (COSEWIC) status report (COSEWIC 2013), a Recovery Strategy (DFO 2014a), and any future Action Plans. Section 2 reproduces the COSEWIC assessment summary, recaps the threats to the population and its critical habitat, along with the recovery objectives, performance indicators, and the critical habitat schedule of studies from the Recovery Strategy. During the reporting period, many activities were undertaken to support the recovery objectives. These activities, along with an assessment of recovery progress according to the performance indicators, are presented in Section 3. Section 4 provides a concluding statement about the implementation of the Recovery Strategy during the reporting period, as well as suggestions to guide future recovery efforts"--Intro.







Marine Faunal Diversity in India


Book Description

More than 70% of the earth’s surface is covered by water, making it an ideal and abundant resource for studying species diversity, faunal communities, and ecosystems. India’s massive coastline (5,044 miles) means it plays a major role in housing these faunal communities. Of the 32 animal phyla, 15 are represented in India’s marine ecosystem, covering more than 15,000 species. Marine and coastal ecosystems of India provide supporting services in the form of wide range of habitats. Major ecosystems such as estuaries, mangroves, coral reefs, lagoons, seaweeds and sea grasses serve as nurseries for both inshore and offshore fishes and others, many of which are supposed to be commercially exploited. Marine Faunal Diversity in India describes different marine faunal group ranges from sponges, corals, mollusks, crabs, fishes, reptiles, birds, marine mammals, mangrove fauna and tsunami impact on marine faunal diversity. The chapters, written by reputed experts in their respective fields, illustrate diversity and distribution of marine faunal communities. Key aspects of the ecology and conservation of this important ecosystem are also discussed. Marine Faunal Diversity in India provides marine biologists and related researchers with access to the latest research and field studies from this major region. Provides the latest field research on marine faunal diversity throughout the vast and species-rich Indian region Brings together expertise from top marine biology researchers in the country Covers a diverse array of aquatic environments, including coastal and island areas Discusses conservation ecology of marine faunal groups




Biology and Ecology of Antarctic Krill


Book Description

This book gives a unique insight into the current knowledge of krill population dynamics including distribution, biomass, production, recruitment, growth and mortality rates. Detailed analysis is provided on food and feeding, reproduction and krill behaviour. The volume provides an overview on the aspects of natural challenges to the species, which involve predation, parasites and the commercial exploitation of the resource and its management. A chapter on genetics shows the results of population subdivision and summarizes recent work on sequencing transcriptomes for studying gene function as part of the physiology of live krill. The focus of Chapter 4 is on physiological functions such as biochemical composition, metabolic activity and growth change with ontogeny and season; and will demonstrate which environmental factors are the main drivers for variability. Further discussed in this chapter are the bottle necks which occur in the annual life cycle of krill, and the mechanisms krill have adapted to cope with severe environmental condition.
