Resource Selection by Animals

We have written this book as a guide to the design and analysis of field studies of resource selection, concentrating primarily on statistical aspects of the comparison of the use and availability of resources of different types. Our in tended audience is field ecologists in general and wildlife biologists in particular who are attempting to measure the extent to which real animal populations are selective in their choice of food and habitat. As such, we have made no attempt to address those aspects of theoretical ecology that are concerned with how animals might choose their resources if they acted in an optimal manner. The book is based on the concept of a resource selection function, where this is a function of characteristics measured on resource units such that its value for a unit is proportional to the probability of that unit being used. We argue that this concept leads to a unified theory for the analysis and interpretation of data on resource selection and can replace many ad hoc statistical methods that have been used in the past.

The Burying Beetle

It was after I ate King that everything started to go wrong in our entire family, as if someone had put an evil spell onto us, a hex - like a bad fairy godmother had said at my birth, when you are eleven you are going to be struck by a sorrow so big it will be like a lightning bolt. There will be grief like a sharp rock in your throat. Twelve-year-old Gussie was born with a rare, life-threatening heart disease, but it hasn't hampered her curiosity. When she reads about the Burying Beetle, which has the unusual habit of burying dead birds, mice, and other small animals by digging away the earth beneath them, it becomes her mission to find one. As she searches the Cornish coast for the elusive insect, Gussie learns to be like the Burying Beetle, to bury things past and to live. BACK COVER Meet Gussie. Twelve yhears old and settling into her new ramshackle home on a cliff top above St Ives, she has an irrepressible zest for life. She also has a life-threatening heart condition.
