Marine Bivalve Mollusks and Emerging Pollutants: Toxicological Impacts provides the most updated and comprehensive knowledge of the toxicological impacts of a variety of emerging pollutants on marine bivalve mollusk species. In addition to synthesizing recent toxicological findings, the book also discusses toxification mechanisms, current challenges, and future research prospects. Written by international experts, this book assesses new advances in the toxicological impacts of pollutants, including microplastics, bromide flame retardants, nanomaterials, pharmaceutical residues, personal care products, pesticides, and perfluorinated compounds. In addition, it details how these can affect reproduction, embryonic development, metabolism, and immune systems of marine bivalves. Behavioral responses and neuroendocrine regulation is also discussed. Toxification mechanisms are interpreted at both physiological and molecular levels. The book concludes with current research and environmental challenges and potentials for further, future study techniques.

Encyclopedia of Fish Physiology, Second Edition is a comprehensive, introductory-level reference work that aims to unite readers in the wonders of this discipline. Chapters highlight where physiological systems and processes are conserved across vertebrate groups, which supports the use of fish as a vertebrate model for investigating fundamental problems in physiology and knowledge transfer to the medical field. Other chapters highlight unique specializations and adaptations that allow fish to survive in challenging environments, leading to a deeper appreciation of the natural world. Final sections demonstrate the consequences of perturbing physiological systems and how this knowledge can empower conservation strategies to protect fish. Much has changed in the field of fish physiology since publication of the previous, Prose award winning, edition. For example, we understand better the impacts of global climate change on the physiological systems of fish, and we have gained a deeper mechanistic understanding of physiological processes through technological advancements such as gene editing with CRISPR, whole genome sequencing, and quantitative 'omic` approaches. The new edition greatly expands the closing thematic section focused on applying fish physiology to real world challenges with topics including ocean acidification, declining habitat quality due to human activities, and the use of zebrafish in biomedical studies on tissue regeneration, neurological disorders and cancer.

The true story of a deeply murderous intent that lurked menacingly beneath the waves during world war two. The torpedoes strike explosively and nine thousand people die - five thousand of them are just defenceless children. Another ship founders after being attacked by a brutal submarine commander and the ship's crew and passengers are used in a murderous kind of blood-sport. Merchant seamen are savagely machine-gunned in the water, callously slaughtered with hand-grenades or simply left to the circling sharks. Inside monsters & marine mysteries you will find:Research on mysterious land cryptids like sasquatch as well as deep-sea lifeMore about sharks - is megalodon alive or is something even nastier out there?Compelling images backed by scientific evidenceInterviews with eyewitnesses and much moreIf you're avoiding fiends that swim with fins, the wagon trail is where you'll fit in! Scaly beasts from the deep try to find a home among the tumbleweeds and desert ranches of the old west. Intense sunshine, sneaky bandits, and angry farmers make it difficult for the monsters to feel welcome, but the locals soon accept the lonesome creatures and throw a shindig in their honor. Whimsical rhymes over thirty full-color illustrations explain why there are no sea monsters in the wild west!
