    Shallow Seas

    Shallow Seas

    Mooi ex. Engelstalige paperback, iets dikker formaat, nog helemaal in nieuwstaat. LIKE NEW. Geillustreerd in kleur.

    Shallow Seas are the most biologically rich and productive areas of the world ocean. This latest New Naturalist volume provides a natural history of this environment and its biological communities.

    The margins of the continents, especially broad in the North Atlantic region, are drowned by shallow seas, creating a sea floor environment which is part of the wider and deepening benthic realm – the ecological region at the lowest level of a body of water such as an ocean or a lake, including the sediment surface and some sub-surface layers. These ‘shelf seas’ are the most biologically rich and productive areas of the world ocean. In his latest New Naturalist volume, Peter Hayward addresses some aspects of the natural history of the benthic environment of the shelf seas of northwest Europe and its biological communities.

    Away from rocky coastlines the seafloor is rather flat, often muddy, beneath turbid water with low or no visibility. Benthic faunas mostly live within the sediment of the seafloor, or are sparsely and patchily distributed upon it, and if at all motile are likely to withdraw into burrows or move quickly away on disturbance. Yet, dredges and grabs reveal an often extraordinary diversity and density of animals, suggestive of complex interacting communities. This is not a textbook of marine benthic ecology, nor is it a comprehensive review of the benthic communities of the northwest European shelf seas. Rather, it describes the natural history of some benthic habitats and associations characteristic of our region.

    Field Guide to the Bees of Great Britain and Ireland

    Engels, paperback, als nieuw

    Bees are a fascinating and indispensable group of insects, but many species are in decline, and efforts to help determine distributions and changes in abundance have to date been compromised by a serious lack of identification resources. This eagerly anticipated new addition to the highly acclaimed British Wildlife Field Guides series will unravel the complexities of identification, and is designed to cater for people new to the bee world as well as to more experienced recorders who wish to identify every species accurately. It provides the latest information on the identification, ecology, status and distribution of all 275 species of bee in Britain, Ireland and the Channel Islands.- Written by Steven Falk, professional naturalist and conservationist with over forty years' experience of working with bees- Illustrated with over 1,000 colour and black & white artworks by Richard Lewington, one of Europe's leading insect artists- Stunning photographs of living insects as seen in the wild- 234 up-to-date distribution maps- Comprehensive introduction to bee classification, ecology, field techniques and recording, a full glossary, and information on how to separate the sexes and distinguish bees from other insects- Introductions to families and genera, describing key characters and life histories- Detailed species descriptions covering field and microscopic characters, similar species, variants, flight season, habitat, flowers visited, nesting habits, status & distribution, and parasites & associates- A series of innovative illustrated keys to genera and species, designed to guide the user step by step through the identification process
