Abstract

Brackish water can be found wherever sea water is diluted by freshwater to form water of intermediate salinity. The ephemeral habitats of estuaries, coastal lagoons and inland seas are rich in fauna, but are threatened by rising sea levels, drainage and reclamation of low lying coastal land, storms and sea defences. This is the first identification guide to the fauna of these ecologically important areas. The ecology of these animals and their habitats are examined and reviewed. The keys are designed to be used with living material, and illustrations are provided for all species likely to be found in brackish-water habitats in northwestern Europe, making identification easy. Fieldworkers, naturalists and students interested in these fragile and ephemeral habitats will find this an indispensable reference.

Abstract

Ecoregions applies the principles described in Bailey's Ecosystem Geography to describe and characterize the major terrestrial and aquatic ecological zones of the Earth. Robert Bailey's system for classifying ecoregions has had a major influence, and has been adopted by major organizations such as the US Forest Service and The Nature Conservancy. This book includes numerous photographs of representative ecoregions, and outstanding color figures are complemented by two full-color maps showing the major ecoregions of the continents and of the oceans.  .

Abstract

Salamandres, tritons, crapauds, grenouilles, lézards et serpents composent le monde des amphibiens et reptiles de Wallonie. Plusieurs espèces sont remarquables, comme le spectaculaire escaladeur qu'est le Lézard des murailles, ou l'Alyte accoucheur dont le mâle transporte la ponte sur son dos. Au total, 21 espèces indigènes, presque toutes confrontées à une dégradation de leur situation, au point que deux amphibiens ont récemment disparu. En regard, la récente multiplication de quelques grenouilles exotiques et les nombreux lâchers de tortues aquatiques sont source d'inquiétude, compte tenu de leurs interactions potentielles avec le reste de la faune indigène. "Amphibiens et Reptiles de Wallonie " est le fruit d'un vaste travail collectif. L'ampleur de la collaboration (plus de 800 contributeurs) est en soi un signal de l'intérêt croissant porté à cette petite faune, encore souvent méconnue et parfois honnie à tort, notamment dans le cas des serpents. L'enquête de terrain a permis de rassembler plus de trente mille données et de dresser un bilan précis pour ce groupe faunique reconnu pour sa sensibilité aux agressions environnementales. L'état des connaissances, l'analyse des problèmes et des pistes pour une meilleure conservation sont détaillés dans cet ouvrage. Il dépasse donc le simple atlas de répartition des espèces au fil d'un ensemble de petites monographies qui abordent l'identification, le cycle de vie, les déplacements, le régime alimentaire, les habitats, la répartition wallonne et dans les régions alentour, les effectifs et les tendances perceptibles pour chaque espèce, y compris celles introduites dans notre environnement naturel.
