Survival and Reproduction of Female Wild Turkeys in New York

Abnormal Eggs of Rio Grande Wild Turkeys on the Edwards Plateau, Texas

“…Survival of hens during the breeding season in our stable region is among the highest reported for Rio Grande wild turkeys (Miller et al 1995), but is similar to values reported for eastern wild turkeys M. g. silvestris (e.g. 0.81 (Palmer et al 1993), 0.74-0.86 (Roberts et al 1995) and 0.72 (Wright et al 1996)). Life-history theory predicts that in variable environments, such as the semiarid regions of Texas (Riskind & Diamond 1988), limiting or foregoing reproduction (i.e.…”

Fall-Winter Survival of Ruffed Grouse in New York State

“…We compared survival distributions using the log-rank test. We used a 2-tailed Z statistic to test for differences in survival rate at the end of the hunting season, with a signifi cance level of = 0.05 (Pollack et al 1989a, Roberts 1993. We compared survival distributions within study areas between years after Migoya and Baldasarre (1995).…”

“…We estimated fall-winter survival through the hunting season for study areas, sexes, and age classes via the Kaplan-Meier product-limit estimator in SAS (Kaplan andMeier 1958, SAS Institute Inc. 1999), using code from White and Garrott (1990) to allow for staggered entry (Pollack et al 1989a, b;Roberts 1993). We compared survival distributions using the log-rank test.…”

Eastern wild turkey nest site selection in two frequently burned pine savannas

“…Wild turkey populations are strongly influenced by reproductive success (Palmer et al 1993, Roberts et al 1995, Roberts and Porter 1996, Miller et al 1999, Thogmartin and Shaeffer 2000, and predation is a driver of this success (Speake 1980, Still and Baumann 1990, Miller and Leopold 1992, Lovell et al 1997. Lower nesting success of turkeys may depend on multi-scale processes including differences in vegetation structure around nest sites, land cover composition and configuration at larger spatial scales, and predator densities (Thogmartin 1999).…”
