Summary of Foreign Game Bird Propagation and Liberations, 1960 to 1963
Author: Gardiner Bump
Publisher:
ISBN:
Category : Animal introduction
Languages : en
Pages : 60
Book Description
State reports covering the propagation and trial liberation of foreign game birds are summarized from the period 1960 through 1963. Details are then provided in tabular form. Of the 21 species and subspecies and 6 crosses reported, only the sandgrouse and the Himalayan snowcock have not yet been produced in numbers in captivity. Increasing consideration is being given to the production of well-reared birds conditioned for survival in the wild following release. In all 78,217 individuals, mostly pheasants, are reported to have been raised for trial liberation from breeders provided through the Foreign Game Introduction Program. These releases supplement 16,145 birds wild-trapped and sent to cooperating States for trial release. While, for most species under trial, it is still too early to evaluate results, some are evident. Iranian pheasants, black francolin and gray francolin have demonstrated the ability to survive, reproduce and increase substantially on release areas. Conversely, Indian sandgrouse and two other species have probably failed to adapt themselves and the semi-domestic strain of Reeve's pheasant is barely hanging on. Six other species are maintaining themselves in numbers sufficient to justify guarded optimism.

Book Description
This compilation summarizes releases of exotic game birds into the United States by 23 States, 1969-78. The 32 entries of taxonomic units include 6 species (and 1 additional subspecies) of tinamous (family Tinamidae) and 13 species (and 12 additional subspecies or hybrid combinations) of partridges and pheasants (family Phasianidae).

Mourning Dove Status Report, 1968

Category : Bird populations
Languages : en
Pages : 38
Book Description
The Density Index of breeding doves declined in each management unit between 1967 and 1968 at the following rate: Eastern, 4 percent ; Central, 2 percent ; Western, 13 percent ; and the entire contiguous United States, 5 percent. Regression analyses suggest that the trend in populations has been downward in all units since 1958. Although biased to an unknown degree, data collected in conjunction with the Annual Waterfowl Mail Questionnaire Survey suggest that the harvest in the United States increased 28.9 percent and that dove hunters (who also purchased duck stamps) increased 31.5 percent during the period 1965-1966 through 1967-1968. The increase in harvest was due chiefly to an increase in hunter numbers.

Conceptual Ecology and Invasion Biology: Reciprocal Approaches to Nature
Author: Marc W. Cadotte
Publisher: Springer Science & Business Media
ISBN: 1402049250
Category : Science
Languages : en
Pages : 506
Book Description
In this edited volume, global experts in ecology and evolutionary biology explore how theories in ecology elucidate the processes of invasion, while also examining how specific invasions inform ecological theory. This reciprocal benefit is highlighted in a number of scales of organization: population, community and biogeographic. The text describes example invaders in all major groups of organisms and from a number of regions around the globe.
