Life usually goes according to a scenario written for you beforehand. You go to school, graduate from college, get a job, get married, etc. Even if some of you have problems with these, you struggle to get what you are meant to have. But what if a ‘system failure’ occurs? What if someone wise and powerful decides to intervene in yourlife? Will such intervention turn out to be a happy blessing, or will it become the test beyond your strength?

Winner of the Marsh Book of the Year Award 2012 by the British Ecological Society. In A Resource-Based Habitat View for Conservation Roger Dennis introduces a novel approach to the understanding of habitats based on resources and conditions required by organisms and their access to them, a quantum shift from simplistic and ineffectual notions of habitats as vegetation units or biotopes. In drawing attention to what organisms actually use and need in landscapes, it focuses on resource composition, structure and connectedness, all of which describe habitat quality and underpin landscape heterogeneity. This contrasts with the current bipolar view of landscapes made up of habitat patches and empty matrix but illustrates how such a metapopulation approach of isolated patchworks can grow by adopting the new habitat viewpoint. The book explores principles underlying this new definition of habitat, and the impact of habitat components on populations, species’ distributions, geographical ranges and range changes, with a view to conserving resources in landscapes for whole communities. It does this using the example of butterflies – the most alluring of insects, flagship organisms and key indicators of environmental health – in the British Isles, where they have been studied most intensively. The book forms essential reading for students, researchers and practitioners in ecology and conservation, particularly those concerned with managing sites and landscapes for wildlife.

The most complete guide to fishing fliesDescribes every type of fly – freshwater and saltwaterCovers flies from around the worldEvery fly is illustrated with a specially taken photographFlies are tied by some of the world’s most famous fly-tiersCollins Fishing Flies is the encyclopaedic guide to the huge range of flies now being used by the modern fly-fisherman, whether they are fishing for the traditional quarry of salmon and trout, chasing bonefish on the tropical flats of the Caribbean, or stalking pike in the cold fens of East Anglia, and everything in between. Collins Fishing Flies not only describes every type of fly used to catch all types of fresh- and saltwater fish, it also describes every type from every country that is currently used. This unique combination allows the fisherman to select flies that may have never been used in their area, or never used to catch that species of fish, or perhaps both, and thus allow the fish to be offered something different.Collins Fishing Flies is divided into fourteen sections:EARLY FLIESNORTH COUNTRY SPIDERSLARVAE & PUPADRY FLIES AND FLOATING FLIESCUT- OR BURNT-FEATHER WINGSUPWINGED FLY SPINNERFANCY WET FLIES OR LOCH/SEA TROUT FLIESSTREAMERS AND BUCKTAILSFLIES FOR SALMON, SEA TROUT AND STEELHEADSHRIMPS AND PRAWNSSALMON DRY FLIESFLIES FOR SEA-RUN TROUT: SEA TROUT, STEELHEAD, CUTTHROAT AND CHARFLIES FOR FRESHWATER PREDATORSSALTWATER FLIESFor each fly the exact recipe is given, with hints on how to tie the perfect fly, plus a specially commissioned photograph of that fly.
