Nudibranchs of Britain, Ireland and Northwest Europe
A strikingly illustrated photographic identification guide to sea slugs in all their colourful variety Nudibranchs, or sea slugs, are a group of marine gastropod molluscs whose adults lack shells, an evolutionary loss that has led to a wide variety of body shapes, colours and colour patterns, making them popular with divers and underwater photographers. In this book, experienced nudibranch experts Bernard Picton and Christine Morrow provide an accessible and authoritative photographic identification guide for anyone interested in finding and identifying nudibranchs in the coastal waters of Britain, Ireland and Northwest Europe. Covers more than 195 species, each on its own two-page spread Includes in situ photos to aid finding nudibranchs under water and on the shore Features photos of nudibranchs’ distinctive spawn coils and studio photos showing detailed anatomy Presents key distinguishing features and essential information on size, habitat, diet and distribution

River Ecology and Management
Touching all parts of the natural environment and nearly all aspects of human culture, streams and rivers act as centres of organization within landscapes. They provide natural resources such as fish and clean water, transportation, energy, diffusion of wastes, and recreation. Today, with unprecedented demands on streams and rivers by an exponentially increasing human population, a basic ecological understanding of the structure and dynamics of running waters is essential for formulating sound management and policy decisions. The vast Pacific coastal ecoregion of the United States contains an extraordinary array of physical settings and examples of the range of dynamics associated with rivers and their management. The interface between the science and policy of natural resource management is illustrated by examples from this ecoregion, including the protection of riparian forest, the marbled murrelet, salmon, and amphibians.

갈대 속의 영원
수천 년 동안 살아남은 책의 환상적인 모험 그리고 책을 지켜온 사람들의 비밀스러운 노력 무엇보다도 현재에 이르기까지 책을 고안하고 지켜낸 사람들에 관한 이야기다. 책은 지금껏 무수한 파괴에 맞서며 자리를 지켜왔다. 화재로부터, 홍수로부터, 분서갱유로부터, 검열로부터. 러시아의 시인 안나 아흐마토바의 열한 명의 친구들은 작가에게 생길지 모르는 불행에 대비해 작가가 쓰고 있던 『레퀴엠』을 모두 암기해뒀다. 그리스어 텍스트는 아프가니스탄과 이란에서까지 발견되며 교육과 문화의 기회가 전파되었음을 증명...
Oceans in Decline
What is happening in our oceans? By describing their main elements, this book shows how and why the oceans are being transformed, and suggests possible future scenarios to address this complex, yet often-asked, question. The ocean is being dramatically transformed, but the magnitude of this transformation remains unclear since the ocean is largely inaccessible and still unknown: there is more information about the outer universe than about the deepest parts of our oceans. The author, a marine biologist with extensive research experience, offers a holistic view of our oceans. Focusing on fishing, pollution and the effects of climate change, he identifies and describes the changes occurring in all marine ecosystems, and discusses the long-passed state of equilibrium.
Anàlisi històrica de la identitat catalana
Anàlisi històrica de la identitat catalana és una obra col·lectiva de recerca històrica que renova la visió del sorgiment de la identitat catalana a l’edat mitjana a partir de vectors com la convergència de trets socioeconòmics, la percepció externa, el desenvolupament institucional i la representativitat política; ressegueix l’adaptació i les expressions d’aquesta identitat sota els canvis dels segles XVI-XVIII; analitza l’adequació, represa i formulació de la identitat catalana dins de l’Espanya contemporània fins a la fi del franquisme, i atén la funció transmissora d’uns eixos transversals al llarg del temps com poden ser la llengua, el dret i l’art. Es tracta d’una publicació emparada per l’Institut d’Estudis Catalans, fruit d’un projecte de recerca europeu de l’European Science Foundation (ESF) i desenvolupat per quatre grups de recerca reconeguts amb la màxima qualificació científica com a grups de recerca consolidats i finançats per l’Agència de Gestió d’Ajuts Universitaris i de Recerca (AGAUR).
