PROCESSES OF POPULATION INCREASE, GEOGRAPHICAL DISTRIBUTION, AND INTERACTIONS WITH PHYSICAL ENVIRONMENT AND OTHER CREATURES ARE ALL EXAMPLES OF THE QUANTITATIVE ASPECT OF MANY OF WILDLIFE ECOLOGY’S MOST PRESSING CHALLENGES. DEALING WITH THESE ISSUES CALLS FOR A CONCEPTUAL KNOWLEDGE OF QUANTITATIVE ECOLOGY. DECISIONS ABOUT WILDLIFE MANAGEMENT AND CONSERVATION OFTEN INCLUDE THE USE OF MATHEMATICAL MODELS. DUE TO THE FACT THAT IT IS UNUSUAL TO BE ABLE TO DEPEND ON ONE’S OWN PRIOR EXPERIENCES TO CHOOSE THE BEST COURSE OF ACTION. EACH ISSUE ARISES IN A NEW PHYSICAL ENVIRONMENT, WITH NEW SPECIES, DIFFERENT DIFFICULTIES, AND DIFFERENT LIMITATIONS. FORTUNATELY, MATHEMATICAL MODELS MAY BE A USEFUL TOOL FOR HANDLING THESE COMPLEXITIES IN A RESPONSIBLE MANNER. MATHEMATICAL MODELS CAN AID IN MAKING CLEAR THE REASONING THAT UNDERLIES HUMAN IDEAS. THE CONSERVATION OF THE ANIMAL POPULATIONS AND THEIR NATURAL ENVIRONMENTS IS GAINING PROMINENCE IN THE FIELD OF WILDLIFE MANAGEMENT. SINCE THIS IS A SIGNIFICANT CHANGE, WE HAVE RECOGNISED TO INCLUDE “CONSERVATION” INTO THE TEXT’S NEW TITLE. THE NEW QUANTITATIVE APPROACHES TO MANAGEMENT DEVELOPED OVER LAST DECADE ARE NOW INTEGRATED AT THE MOST FOUNDATIONAL LEVELS. IN ADDITION, THE BOOK HAS VARIOUS CHAPTERS THAT MIGHT BE OF SERVICE TO PROFESSIONAL WILDLIFE MANAGERS.
