Zoologi: fisk (iktyologi)

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.

"Tales of rewards and challenges experienced while studying amphibians and reptiles in nature. Written by fifty herpetologists from around the world, the stories reveal the passion these field herpetologists have for adventure, exploration, and discovery and the love they have for the animals they study"--

Hver beskrivelse afsluttes med tips til, hvordan man lettest får fisken på krogen. Sidst i bogen findes en faktaside om fisk og fiskeri.Bogen er en del af serien ”Opdag naturen”, hvor der foreligger tre andre titler, der alle er udgivet på forlaget Bogoo. Emma Jansson er en svensk forfatter og tegner. Hun holder rigtigt meget af naturen. Emma Jansson står bag de populære bøger ”Mine første fugle”, ”Mine første bær og svampe” og ”Mine første blomster og spiselige planter”.

In this groundbreaking work Anthonie Cornelis Oudemans, explores the mysterious and elusive creature known as the great sea-serpent. Originally published in 1892, this book remains one of the most comprehensive and well-researched studies of sea serpents to date. Oudemans became immensely fascinated by this often enormous creature, and spent three years of intensive research before publishing his work.He argues for the existence of a sea-serpent that can grow up to 60 feet long, which, according to the many recorded sightings, often resembles a prehistoric Plesiosaur. Oudemans relied on nearly 200 eyewitness accounts and many publications, and named the creature Megophias Megophias in Latin, in accordance with scientific convention. However, Oudemans' colleagues did not approve of his work on sea monsters, as they believed such creatures could not exist. Despite this, his work gained recognition posthumously. In the 1950s, Belgian biologist Bernard Heuvelmans rediscovered Oudemans' work and found in his sea-serpent the missing link in cryptozoology.This new revised edition features a clear distinction between Oudemans' ongoing text and the many included eyewitness accounts, as well as all original images that have been cleaned up for clarity. Additionally, readers will find a Post Scriptum containing biographical information about the author and - as a bonus - the first English translation of Oudemans' original 1934 Dutch-language essay on the Loch Ness Monster.WITH 82 ILLUSTRATIONS

"This new edition is a modified version of our 2012 book, updated to reflect advances in the knowledge of the natural history of snakes, and improvements in their taxonomy and classification"--Page 6 of ECIP galley.

Med FISK – scaled-up får man et fuldstændig unikt billede af den dyregruppe, der befolker to tredjedele af vor klodes areal, her med specielt fokus på arter i danske farvande, og hvis livsbetingelser vi i højere og højere grad skal værne om. FISK – scaled-up er en reminder til os alle om deres skønhed og deres eksistensberettigelse.Bogens hovedattraktion er billederne, hvor Søren Skarbys objektiv har kunnet forstørre fiskene og tillade, at vi kommer helt, helt tæt på disse, overraskende, meget farvestrålende danske arter. Med sine utroligt skarpe og usædvanlige billeder og med tekstbeskrivelser af 27 danske fiskearter sættes der fokus på fisks skønhed og vores lokale havbiodiversitet. De 27 fotograferede arter repræsenterer de fleste fiskefamilier i både fersk- og saltvand herhjemme, og på den måde fortælles der om de fleste former for liv med finner i dansk farvand.Udgivelsen giver læseren mulighed for at se forskellige fiskearter med helt andre øjne og samtidigt læse en beskrivelse af hver enkelt art.Bogen er trykt med åben ryg (uden lim i ryggen), så fotografierne virkelig kommer til deres ret, når de breder sig over et helt opslag.Søren Skarby (f. 1964) er uddannet pressefotograf. Han har haft sin egen freelancevirksomhed siden 1990 primært med base i Svendborg, hvor han skriver og fotograferer for en lang række dag- og fagblade, magasiner, virksomheder og offentlige institutioner. Han har foretaget adskillige reportagerejser rundt i hele verden, men særligt Mellemøsten og Arktis har været et tilbagevendende rejsemål.
