Chapter 20: Protecting Marine Mammals and Endangered Marine Species
Preliminary Report CHAPTER 20: PROTECTING MARINE MAMMALS AND ENDANGERED MARINE SPECIES Protection for marine mammals and endangered or threatened species from direct impacts has increased since the enactment of the Marine Mammal Protection Act in 1972 and the Endangered Species Act in 1973. However, lack of scientific data, confusion about permitting requirements, and failure to adopt a more ecosystem-based management approach have created inconsistent and inefficient protection efforts, particularly from indirect and cumulative impacts. Consolidating and coordinating federal jurisdictional authorities, clarifying permitting and review requirements for activities that may impact marine mammals and endangered or threatened species, increasing scientific research and public education, and actively pursuing international measures to protect these species are all improvements that will promote better stewardship of marine mammals, endangered or threatened species, and the marine ecosystem. ASSESSING THE THREATS TO MARINE POPULATIONS Because of their intelligence, visibility and frequent interactions with humans, marine mammals hold a special place in the minds of most people. Little wonder, then, that mammals are afforded a higher level of protection than fish or other marine organisms. They are, however, affected and harmed by a wide range of human activities. The biggest threat to marine mammals worldwide today is their accidental capture or entanglement in fishing gear (known as “bycatch”), killing hundreds of thousands of animals a year.1 Dolphins, porpoises and small whales often drown when tangled in a net or a fishing line because they are not able to surface for air. Even large whales can become entangled and tow nets or other gear for long periods, leading to the mammal’s injury, exhaustion, or death. -

Harmful Environmental Exposures and Vulnerable Populations Environmental Health in Nursing
Unit II: Harmful Environmental Exposures and Vulnerable Populations Environmental Health in Nursing Unit 1I: Harmful Environmental Exposures and Vulnerable Populations INTRODUCTION Unit 1 highlighted various roles of the nursing profession where knowledge of environmental exposures is central to practice. In Unit 2, the focus is upon population groups who are most vulnerable to harmful environmental exposures. While risks to adverse health outcomes can vary according to geography, housing and location of environmental exposures, some humans are at greater risk due to their biophysical and sociopolitical vulnerability. Unit 2 explains risk and vulnerability across the lifespan with a focus upon specific vulnerabilities and harmful effects at various developmental stages. A second chapter highlights anticipatory guidance for parents and caregivers to reduce environmental exposures for children from infancy to adolescence. Third, Unit 2 considers the impact of social determinants of health, which are commonly referred to as factors where people live, learn, work, play and pray. Social determinants at neighborhood and community levels impact individual level exposures. Finally, Unit 2 includes a chapter about the effects of social determinants on the vulnerability of immigrants and refugees. See Unit 5: Sustainable Communities, for the chapter about Environmental Justice, which addresses the adverse outcomes for those who live in more environmentally hazardous areas.

Issue 1, Dec 2019 Distribution and Abundance in India
OCEAN DIGEST Quarterly Newsletter of the Ocean Society of India Volume 6 | Issue 1 | Dec 2019 | ISSN 2394-1928 Ocean Digest Quarterly Newsletter of the Ocean Society of India Marine Mammals — Indian Scenario Chandrasekar Krishnamoorthy Centre for Marine Living Resources & Ecology Ministry of Earth Sciences, Kochi arine mammals, the most amazing marine organisms on earth, are often referred to as “sentinels” of ocean Porpoising - Striped dolphin health.M These include approximately 127 species belonging to three major taxonomic orders, namely Cetacea (whales, dolphins, and porpoises), Sirenia (manatees and dugong) and Carnivora (sea otters, polar bears and pinnipeds) (Jefferson et al., 2008). These organisms are known to inhabit oceans and seas, as well as estuaries, and are distributed from the polar to the tropical regions. These organisms are the top predators in many ocean food webs except the sirenians, which are herbivores. However, cetaceans become the dominant group of marine mammals, as well as widest geographic range. Marine mammals have been deemed “invaluable components” of the naval force as their natural senses are superior to technology in rough weather and noisy areas. India, with a rich diversity of marine mammals has a history of documenting these animals for the last 200 years. Leaping - Spinner dolphin However, until the year 2003, information on these organisms in our seas was restricted to incidental capture by fishing gears and stranding records (Vivekanandan and Jeyachandran, 2012). Published reports indicate that only a few scientific studies have addressed the distribution of marine mammals in the Indian EEZ, and there exist huge lacunae on the baseline information such as abundance and density for many species due to limited resources and lack of systematic surveys. -

Almost all crime at sea takes place beyond the horizon line, hidden from view. This vast wilderness is exploited not only for fish, but as a hiding place for criminal activities. Stolen fish are caught illegally, evading a wide range of safeguards to undercut the costs of doing business. Blatant violation of catch limits, gear restrictions and safety precautions are frequently carried out by a small fraction of fishermen, undermining the efforts of responsible “Illegal, unregulated and unreported fishing is a fishing companies.

Best Fish for Your Health and the Sea's
Nova In Vitro Fertilization Best Fish for Your Health and the Sea's By The Green Guide Editors (National Geographic) Fish provide essential nutrients and fatty acids—especially for developing bodies and brains and make a perfect protein-filled, lean meal whether grilled, baked, poached or served as sushi. Yet overfishing, habitat loss and declining water quality have wreaked havoc on many fish populations. Furthermore, many are contaminated with brain-damaging mercury and other toxic chemicals. If the pickings appear slim, check out our "Yes" fish where you'll find many options available. As for our "Sometimes" fish, these may be eaten occasionally, while "No" fish should be avoided entirely. Photograph Courtesy Shutterstock Images Warnings are based on populations of highest concern (children and women who are pregnant, nursing or of childbearing age). To learn which fish from local water bodies are safe to eat, call your state department of health, or see www.epa.gov/waterscience/fish. Besides mercury, toxins can include PCBs, dioxins and pesticides. In compiling this list, the Green Guide referred to resources at the web sites of the Food and Drug Administration, Monterey Bay Aquarium, Environmental Working Group, Environmental Defense Foundation and Oceana among others.

Multiple Stable States and Regime Shifts - Environmental Science - Oxford Bibliographies 3/30/18, 10:15 AM Multiple Stable States and Regime Shifts James Heffernan, Xiaoli Dong, Anna Braswell LAST MODIFIED: 28 MARCH 2018 DOI: 10.1093/OBO/9780199363445-0095 Introduction Why do ecological systems (populations, communities, and ecosystems) change suddenly in response to seemingly gradual environmental change, or fail to recover from large disturbances? Why do ecological systems in seemingly similar settings exhibit markedly different ecological structure and patterns of change over time? The theory of multiple stable states in ecological systems provides one potential explanation for such observations. In ecological systems with multiple stable states (or equilibria), two or more configurations of an ecosystem are self-maintaining under a given set of conditions because of feedbacks among biota or between biota and the physical and chemical environment. The resulting multiple different states may occur as different types or compositions of vegetation or animal communities; as different densities, biomass, and spatial arrangement; and as distinct abiotic environments created by the distinct ecological communities. Alternative states are maintained by the combined effects of positive (or amplifying) feedbacks and negative (or stabilizing feedbacks). While stabilizing feedbacks reinforce each state, positive feedbacks are what allow two or more states to be stable. Thresholds between states arise from the interaction of these positive and negative feedbacks, and define the basins of attraction of the alternative states. These feedbacks and thresholds may operate over whole ecosystems or give rise to self-organized spatial structure. The combined effect of these feedbacks is also what gives rise to ecological resilience, which is the capacity of ecological systems to absorb environmental perturbations while maintaining their basic structure and function. -
