Monitoring Vertebrate Populations


Book Description

This book is written to serve as a general reference for biologists and resource managers with relatively little statistical training. It focuses on both basic concepts and practical applications to provide professionals with the tools needed to assess monitoring methods that can detect trends in populations. It combines classical finite population sampling designs with population enumeration procedures in a unified approach for obtaining abundance estimates for species of interest. The statistical information is presented in practical, easy-to-understand terminology. - Presented in practical, easy-to-understand terminology - Serves as a general reference for biologists and resource managers - Provides the tools needed to detect trends in populations - Introduces a unified approach for obtaining abundance estimates










Management of Amphibians, Reptiles, and Small Mammals in North America


Book Description

Historically the management of public lands from a multiple use perspective has led to a system that emphasizes those habitat components or faunal elements that primarily resulted in some sort of definable economic value. While this often benefitted other species that were not even considered in the original prescriptions, it also negatively impacted others. We no longer can afford to take this simplistic view of ecosystem management. We need to use a more holistic approach where ecological landscapes are considered as units, and land management practices incorporate all elements into an integrated policy. This includes examining the impacts of proposed land uses on amphibian, reptile, and small mammal populations.




Analysis of Wildlife Radio-Tracking Data


Book Description

With the substantial advances in the miniaturization of electronic components, wildlife biologists now routinely monitor the movements of free-ranging animals with radio-tracking devices. This book explicates the many analytical techniques and computer programs available to extract biological information from the radio tracking data. - Presentation of software programs for solving specific problems - Design of radio-tracking studies - Mechanics of data collection - Estimation of position by triangulation - Graphic presentation of animal migration, dispersal, fidelity, and association - Home range estimation, habitat utilization, and estimation of survival rates and population size
