Regulation of nematode fecundity in the ring-necked pheasant (Phasianus colchicus): not just density dependence.
Patterns of nematode fecundity were investigated for infections of the caecal worm Heterakis gallinarum in the ring-necked pheasant (Phasianus colchicus). Worm length was a good predictor of parasite fecundity. After controlling for worm length no other factors, including parasite intensity, were related to worm fecundity. Density dependence in worm size was detected in natural infections at pa...
متن کاملSerum Biochemical Parameters in the Ring-Necked Pheasant (Phasianus colchicus) on Breeding Season
The influence of sex on serum biochemical parameters was investigated in adult (52 week-old) ring-necked pheasants on reproductive activity. Statistical comparisons were made for differences in values between male and female birds. Adult females had higher values for serum total protein and albumin. Significant variations were not observed in the analyses in relation to the sex of the birds for...
متن کاملLong‐term and widespread changes in agricultural practices influence ring‐necked pheasant abundance in California
Declines in bird populations in agricultural regions of North America and Europe have been attributed to agricultural industrialization, increases in use of agrochemical application, and increased predation related to habitat modification. Based on count data compiled from Breeding Bird Survey (BBS) from 1974 to 2012, Christmas Bird Count (CBC) collected from 1914 to 2013, and hunter data from ...
متن کاملRing-Necked Pheasant Hens Select Managed Conservation Reserve Program Grasslands for Nesting and Brood-Rearing
The Conservation Reserve Program (CRP) has provided critical wildlife habitat for many species since 1985. However, the quality of this habitat for early successional species, such as ring-necked pheasant (Phasianus colchicus), may decrease with field age. Late successional grasslands may lack valuable vegetative and structural diversity needed by pheasants, especially during nesting and brood-...
