Survival of Male Merriam's Turkeys in the Wyoming Black Hills
… annual survival rates were calculated in Program MARK and were different between years and among age classes, with the exception of the between-year comparison for 2 year old birds. Extrapolated annual survival rates were 0.1539 for jakes in 2008 and 0.4929 in 2009; 0.1827 for 2 year olds …

Survival of Male Merriam's Wild Turkeys in the Northern Black Hills of South Dakota
… wild turkeys (n = 137) were captured and radio-marked during January and February of 2008 and 2009. Marked turkeys were monitored two to four times per week during the field season of January through the end of May in 2008 and 2009. Mortality sources during this study included hunting (both …

Survival, family breakups, and dispersal of yearling and subadult black bears in western Virginia
… Virginia during 1999 - 2002. We captured and marked 307 different individual yearling and subadult bears on 2 study sites, and attached ear tag transmitters or radio collars to 54 (34M : 20F) 1-year-old, 52 (23M : 29F) 2-year-old, and 35 (8M : 27F) 3-year-old black bears. We used the known …

Dangerous misperceptions with consequences: survival of Eastern cottontails on restored grasslands surrounded by agriculture
… these effects, large-scale restoration programs have been developed. In the Midwestern United States, where tallgrass prairies have been reduced by >99%, the Conservation Reserve Program has created patches of grassland habitat within a larger matrix dominated by agricultural fields that …

Nesting Ecology Of Red-Headed Woodpeckers (Melanerpes Erythrocephalus) In Central Minnesota
… on the study site were color banded, and using Program MARK, I analyzed mark-resighting data using a Cormack-Jolly-Seber (CJS) model to estimate annual apparent survival and detection probability. In the most parsimonious model, apparent survival varied by year and detection probability differed …

Population Ecology of Rocky Mountain Elk in the Black Hills, South Dakota and Wyoming
… and cause–specific mortality using individually marked adult cow and neonate elk (Cervus elaphus) occupying the southwestern region of the Black Hills. We used known-fate analysis in Program MARK for survival analysis of adult cows and calves. We estimated survival and cause-specific mortality of …

Nesting and Brood-Rearing Success and Resource Selection of Greater Sage-Grouse in Northwestern South Dakota
… Female sage-grouse were captured and radio-marked (n = 53) on traditional display grounds. Radio-marked hens were tracked to estimate nesting effort, nest success, and associated habitats. Nest initiation was 95.9%, with an overall nest success of 45.6 ± 5.3%. Hens selected habitats with …

Nesting Success of Grassland Birds in Fragmented and Unfragmented Landscapes of North Central South Dakota
… grassland. I used the nest survival model in program MARK to determine nest survival probabilities as a function of vegetation, patch and landscape variables. I also used logistic regression to construct models to evaluate the influence of vegetation, patch and landscape variables on the …

Using Noninvasive Genetic Sampling to Assess and Monitor Grizzly Bear Population Status in the Northern Continental Divide Ecosystem
… no rigorous data were available to evaluate the program’s success. We assessed population status using data from a large noninvasive genetic sampling project and 33–years of physical captures. Our abundance estimate, Nˆ= 765 (CV = 3.8%), was more than double the working estimate. Based on our …

Analyses of Greater Sage-Grouse (Centrocercus urophasianus) Translocation Release Methods and Chick Survival in Strawberry Valley, Utah
… of chick mortality. Survival data on radio-marked chicks were analyzed using a known fate model in program MARK. Chick survival in Strawberry Valley was greater than all reported estimates from other studies. Our study did not identify any unsuspected causes of chick mortality, and the …

An Evaluation of Duck and Ring-Necked Pheasant Nest Survival and Nest Density in Relation to Patch Size and Landscape Variables in Eastern South Dakota
… 2008 and 2009. I analyzed nest survival data in Program MARK and developed models that best explain the interactions between nest survival and vegetation variables, patch size, presence of woody cover, and landscape composition. Three out of four duck species exhibited increased nest survival in …

Towards the ecology and conservation of sand lizard (Lacerta agilis) populations in Southern England
… 17.5oC and 27.5oC.<br/><br/>An intensive capture-mark-recapture study was performed on independent sand lizard populations and pattern matching software was used to assist with the identification of individual sand lizards from their dorsal patterning. The low recapture rate of sand lizards proved …

Evaluating the Use of Autonomous Recording Units to Monitor Yellow Rails, Nelson's Sparrows, and Le Conte's Sparrows
… and used the robust design occupancy model in program MARK to estimate detection probabilities for each species by survey method. I found, on average, that ARUs detected 0.59 (LCSP), 0.76 (NESP), and 1.01 (YERA) fewer individuals per survey than were detected using the standard protocol. …

The Program Goes South: Australian Prose and the University, 1970-2020
‘Is the creative writing program’, Mark McGurl archly wonders in his landmark work of literary history *The Program Era* (2009), ‘an exceptionally *American* phenomenon?’ As he is well aware, the last half-century has seen the establishment of such programs throughout and beyond the anglosphere. If …

An Evaluation of Adult Freshwater Mussels Held in Captivity at the White Sulphur Springs National Fish Hatchery, West Virginia
… estimated (August 2002 to August 2003) using the program MARK. Glycogen, protein, and lipid concentrations in mantle tissue of three captive species (Actinonaias ligamentina, Cyclonaias tuberculata, and Tritogonia verrucosa) were compared to those of wild mussels in the New River. Gametogenic …

Monitoring for Chronic Wasting Disease in Mule Deer and White-Tailed Deer at Wind Cave National Park: Investigating an Emerging Epizootic
… type, and capture, using known-fate analysis in Program MARK as a precursory evaluation for multi-state modeling. We created multi-state models within Program MARK using a capture-recapture framework with 3 states: 1) 1= alive; 2) A = dead with CWD; and 3) B = dead, non-CWD. Transition …

Habitat selection and survival of juvenile black-capped vireos during the post-fledging period
… of 71 juveniles and, using known-fate models in Program MARK, estimated overall post-fledging survival to be 55% (86% for females and 40% for males). Movement patterns varied among individuals and males tended to make more foray movements than females. Both sexes were frequently seen in …

Fitness and Implications of Reproductive Decisions for Black Brant Nesting on the Yukon-Kuskokwim Delta, Alaska
… and nesting data were used from 2338 marked pairs of brant from the Tutakoke River colony in southwest Alaska. The Barker model in program MARK was used to examine effects of mate loss on annual survival, reporting rate, and permanent emigration. The best supported CMR model allowed …
