The estimation of survival distributions for radio-tagged animals is important to wildlife ecologists. Allowance must be made being lost (or censored) due radio failure, loss, or emigration the animal from study area. Kaplan-Meier procedure (Kaplan and Meier 1958), widely used in medical studies subject censoring, can applied this problem. We developed a simple modification that allows new added after has begun. present 2 examples using telemetry data collected northern bobwhite quail...

ABSTRACT DNA‐based mark‐recapture has become a methodological cornerstone of research focused on bear species. The objective such studies is often to estimate population size; however, doing so frequently complicated by movement individual bears. Movement affects the probability detection and assumption closure required in most models. To mitigate bias caused individuals, size density estimates are adjusted using ad hoc methods, including buffering minimum polygon trapping array. We used...

Education programs designed to reduce conflicts between American black bears (Ursus americanus) and humans are often implemented by diverse groups of wildlife practitioners who may devote significant resources these programs, yet little has been done characterize the content, structure, effectiveness programs. We review 6 education in North America. build on a common performance indicator used 5 programs—a reduction number bear–related complaints authorities—and suggest that incorporate...

Abstract Outreach programs are interventions that have the potential to influence unique context of human–wildlife conflict as well political, economic, and social systems within which occurs. However, evaluation these is limited. The purpose this research was determine a outreach intervention's effect on environmentally responsible behavior using case human–black bear in New York, York NeighBEARhood Watch Program, Elaboration Likelihood Model. We found no short‐term evidence change after...

SummaryWith the introduction of changes to our health service in April 1991, we found that patients infertility clinic and vitro fertilisation were becoming increasingly concerned about how reforms would affect them. Many funding for drugs they required.We conducted a survey local general practitioners try determine their management infertile couple, with particular reference prescribing drugs. There seem be only small decline number likely refer treatment or prepared prescribe these since reforms.

The attitudes and feelings of people concerning conservation policies wildlife conflicts affect their behaviour, understanding this is important in involving local planning decision-making processes. This paper examines these issues Jigme Singye Wangchuck National Park, located central Bhutan. A survey 274 house-holds was carried out to assess farmers' perceptions the influence Park management protection regimes on traditional resource uses, towards set forth Forest Nature Conservation Act...

Summary OBJECTIVE The association of adrenal hyperactivity with ovarian dysfunction may involve direct inhibition steroidogenesis by glucocorticoids. Therefore, the objectives this study were to investigate effects Cortisol on luteinizing hormone (LH) action in human granulosa‐lutein cells and modulation interaction 11 β ‐Miydroxysteroid dehydrogenase (11βHSD). DESIGN AND PATIENTS Effects investigated cultured isolated from follicular aspirates 14 patients undergoing oocyte collection for...

AbstractWhite-tailed deer (Odocoileus virginianus) are managed to yield diverse impacts, including effects ecosystems. Many conventional hunting systems manage abundance through rules that strive produce recreation opportunities and an equitable distribution of antlered bucks among hunters. To protect against excessive harvests, antlerless harvests often regulated quotas. This approach is effective when productivity does not outstrip capacity the hunter population harvest required numbers...

New York State's Adirondack Park is home to an estimated 6,000 black bears (Ursus americanus), about 75% of the state's total population. Human-bear interactions at Park's nearly 100 campgrounds are commonplace. Some conflicts that include risks personal safety and property damage. Between 19 June 2003 18 August 2003, we interviewed 54 campers caretakers 7 determine stakeholder-perceived risks. We structured interviews assess 9 possible constructs influencing not yet reported in literature...

In the protected areas of Bhutan, crop damage by wildlife impacts livelihoods local agropastoralists. We interviewed a stratified-random sample 274 farmers living in Jigme Singye Wangchuck National Park an attempt to better understand and manage growing concerns. Most suffered major financial losses annually due wild pigs (Sus scrofa), barking deer (Muntiacus muntjak), macaques (Macaca mulatta), sambars (Cervus unicolor). All respondents reported animals, pig was most common cause (97%)....

We explored factors influencing people's perceptions of human–wildlife interactions in residential areas, reporting to authorities, and potential conservation implications. Data were obtained from a mail survey 1,439 landowners. used logistic regression predict probabilities having non-positive authorities. Our models predicted relatively well; included attitudes toward wildlife, experiences with age, urban or rural upbringing, location current residence. did not reports satisfactory...

Interactions between humans and white-tailed deer (Odocoileus virginianus) have become common, often resulting in management actions to mitigate negative impacts. Changes population size are generally used judge actions. We examined estimation techniques during 2 mark-resighting experiments a woodland- grassland habitat central New York State suburban area. compared program NOREMARK, Lincoln-Peterson estimates, Jacobson's (1997) buck:doe ratios (BDR) for estimating abundance. In the fi rst...

Abstract After decades of high deer populations, North American forests have lost much their previous biodiversity. Any landscape‐level recovery requires substantial reductions in herds, but modern societies and wildlife management agencies appear unable to devise appropriate solutions this chronic ecological human health crisis. We evaluated the effectiveness fertility control hunting reducing impacts at Cornell University. estimated spring populations planted Quercus rubra seedlings assess...

Breeding behavior ofradio-tagged northern bobwhite (Colinus uirginianus) was observed at Fort Bragg Military Reservation (n = 19), North Carolina, in 1985-88, and Tall Timbers Research Station 27), Florida, during 1984-86. We apparent polygamous breeding 95% (18 of 19) the radio-tagged Bragg, 93% (25 27) birds Timbers. documented 5 cases double-clutching by females. Twenty-seven percent clutches 30), 20% 56) were incubated males. Northern exhibited characteristics both rapid multiclutch am...

Urban wildlife management is growing in importance the U.S. and Canada. This paper describes archetypical history of population exploitation, recovery, impact management, anthropogenic root-causes for many species urban environments. Although traditional situations differ ways, both contexts, some are welcome to co-exist with humans, while other considered intolerable. Management approaches techniques tailored still early days development. issues tend be “wicked problems” (problems where...

Growing populations of resident Canada geese (Branta canadensis) have caused increased nuisance problems in urban and suburban communities. Hazing, or persistent harassment, is often recommended as a nonlethal management strategy to alleviate these problems. Does hazing simply cause local redistribution birds, can it solve by pushing rural areas where hunting mortality could reduce the population? To answer this question, we marked 368 adult 400 juvenile with leg bands 1 community western...
