Book Description
Nonconsumptive outdoor recreation has increased greatly in recent years, and there is growing concern about the effects of such activities on wildlife and wildlife habitats. Unfortunately, information concerning these effects is scare and widely scattered. To stimulate research and assist resource planners and managers in utilizing available information, an annotated bibliography of human-wildlife interactions is provided. The report reviews interactions between wildlife and humans participating in nonconsumptive outdoor recreation activities. Also provided are indexes to authors, species, keywords and geographic regions; an annotated list of keywords; and a list of bibliographies on related topics.

Book Description
Most mourning doves (Zenaida macroura) banded in eastern Missouri in 1968-76 and recovered outside the State moved south-southeast into Kentucky, Tennessee, Mississippi, Alabama, Georgia, Florida, and South Carolina. Most doves banded in central and western Missouri and recovered elsewhere moved south-southwest into Kansas, Oklahoma, Louisiana, Texas, Mexico, and Central America. Several central Missouri doves moved southeast.

Book Description
A banding program for mourning doves (Zenaida macroura) was conducted by the 14 Central Management Unit (CMU) States and the U.S. FIsh and Wildlife Service during 1967-74. Banding and recovery records, as well as data from annual call-count and harvest surveys, were subsequently analyzed by a subcommittee of the Central Migratory Shore and Upland Game Bird Technical Committee. This paper presents information on mourning dove habitat, hunting regulations, and harvest in the CMU; distribution and derviation of band recoveries in and from CMU; distribution of mourning dove harvest in Mexico and Central America; chronology of migration; survival and recovery rates; effects of hunting on CMU mourning dove populations; and indirect nationwide mourning dove population estimates.

Book Description
This paper describes a technique for ordering wildlife information according to physical strata and vegetative structure so that a variety of statistical analyses can be accomplished. Individual wildlife species are assigned to cells in a species-habitat matrix on the basis of feeding and breeding activities within physical strata in representative types of vegetative cover: the cells within the species-habitat matrix are assigned numeric values. The statistical analyses are thus based on the areas that individual species occupy within the species-habitat matrix. Computer graphics are used to represent the structure of wildlife communities and cluster analysis routines are used to describe the potential wildlife guilds that may exist in different vegetative communities. Different numbers of wildlife guilds will occur in species and presumably also of wildlife guilds present within a type of cover is modified by physical attributes of the vegetation within that cover type. The products of this analytical technique may be suitable for evaluating habitat quality, impact assessments, regional inventories and assessments of wildlife resources, and land-use planning activities.
