Population dynamics and harvest management of eastern mallards
Managing sustainable harvest of wildlife populations requires regular collection of demographic data and robust estimates of demographic parameters. Estimates can then be used to develop a harvest strategy to guide decision-making. Mallards (Anas platyrhynchos) are an important species in the Atlantic Flyway for many users and they exhibited exponential growth in the eastern United States betweenAuthorsAnthony J. Roberts, Jeffrey A. Hostetler, Joshua C. Stiller, Patrick K. Devers, William LinkMonitoring abundance of aggregated animals (Florida manatees) using an unmanned aerial system (UAS)
Imperfect detection is an important problem when counting wildlife, but new technologies such as unmanned aerial systems (UAS) can help overcome this obstacle. We used data collected by a UAS and a Bayesian closed capture-mark-recapture model to estimate abundance and distribution while accounting for imperfect detection of aggregated Florida manatees (Trichechus manatus latirostris) at thermal reAuthorsHolly H Edwards, Jeffrey A. Hostetler, Bradley M Stith, Julien MartinA hidden Markov model for estimating age-specific survival when age and size are uncertain
Estimates of age-specific survival probabilities are needed for age-structured population models and to inform conservation decisions. However, determining the age of individuals in wildlife populations is often problematic. We present a hidden Markov model for estimating age-specific survival from capture–recapture or capture–recapture–recovery data when age is unknown and indicators of age, suchAuthorsTimothy A. Gowan, Michael D. Tringali, Jeffrey A. Hostetler, Julien Martin, Leslie I. Ward-Geiger, Jennifer M JohnsonReconstructing population dynamics of a threatened marine mammal using multiple data sets
Models of marine mammal population dynamics have been used extensively to predict abundance. A less common application of these models is to reconstruct historical population dynamics, filling in gaps in observation data by integrating information from multiple sources. We developed an integrated population model for the Florida manatee (Trichechus manatus latirostris) to reconstruct its populatioAuthorsJ. Hostetler, Julien Martin, M. Kosempa, H. Edwards, K. Rood, S. Barton, Michael C. RungeUpdated statewide abundance estimates for the Florida manatee
Knowing how many manatees live in Florida is critical for conservation and management of this threatened species. Martin et al. (2015) flew aerial surveys in 2011–2012 and estimated abundance in those years using advanced techniques that incorporated multiple data sources. We flew additional aerial surveys in 2015–2016 to count manatees and again applied advanced statistical techniques to estimateAuthorsJeffrey A. Hostetler, Holly H. Edwards, Julien Martin, Paul SchuellerStatus and threats analysis for the Florida manatee (Trichechus manatus latirostris), 2016
Trichechus manatus (West Indian manatee), especially T. m. latirostris, the Florida subspecies, has been the focus of conservation efforts and extensive research since its listing under the Endangered Species Act of 1973. To determine the status of, and severity of threats to, the Florida manatee, a comprehensive revision and update of the manatee Core Biological Model was completed and used to peAuthorsMichael C.

MahonStatus and threats analysis for the Florida manatee (Trichechus manatus latirostris), 2012
The endangered West Indian manatee (Trichechus manatus), especially the Florida subspecies (T. m. latirostris), has been the focus of conservation efforts and extensive research since its listing under the Endangered Species Act. On the basis of the best information available as of December 2012, the threats facing the Florida manatee were determined to be less severe than previously thought, eithAuthorsMichael C. Runge, Catherine A. Langtimm, Julien Martin, Christopher J. FonnesbeckEstimating migratory connectivity of birds when re-encounter probabilities are heterogeneous
Understanding the biology and conducting effective conservation of migratory species requires an understanding of migratory connectivity – the geographic linkages of populations between stages of the annual cycle. Unfortunately, for most species, we are lacking such information. The North American Bird Banding Laboratory (BBL) houses an extensive database of marking, recaptures and recoveries, andAuthorsEmily B. Cohen, Jeffrey A. Hostelter, J. Andrew Royle, Peter P. MarraEffects of harvest and climate on population dynamics of northern bobwhites in south Florida
Context: Hunting-related (hereafter harvest) mortality is assumed to be compensatory in many exploited species. However, when harvest mortality is additive, hunting can lead to population declines, especially on public land where hunting pressure can be intense. Recent studies indicate that excessive hunting may have contributed to the decline of a northern bobwhite (Colinus virginianus) populatioAuthorsV. Rolland, J.A. Hostetler, T.C. Hines, Fred A. Johnson, H. Franklin Percival, M.K. OliFactors influencing reproductive performance of northern bobwhite in South Florida
Reproductive success is a critical component of individual fitness, and also an important determinant of growth rates of populations characterized by early maturity and high fecundity. We used radiotelemetry data collected during 2003–2008 to estimate reproductive parameters in a declining northern bobwhite (Colinus virginianus) population in South Florida, and to test hypotheses regarding factorsAuthorsV. Rolland, J.A. Hostetler, T.C. Hines, H. Franklin Percival, M.K. OliPatterns of space and habitat use by northern bobwhites in south Florida, USA
The manner by which animals use space and select resources can have important management consequences. We studied patterns of habitat selection by northern bobwhites (Colinus virginianus) on Babcock-Webb Wildlife Management Area, Charlotte County, Florida and evaluated factors influencing the sizes of their home ranges. A total of 1,245 radio-tagged bobwhites were monitored for 19,467 radio days dAuthorsA. Singh, T.C. Hines, J.A. Hostetler, H. Franklin Percival, M.K. OliImpact of harvest on survival of a heavily hunted game bird population
Context. Despite their economic importance and intensive management, many game bird species, including the northern bobwhite Colinus virginianus, are in decline. Declines may be explained, at least in part, by low survival due perhaps to poor habitat quality, high predation or excessive hunting pressure.Aims.
