Using mark-recapture methods to estimate population size and survival of pyjama sharks (Poroderma africanum) in Mossel Bay, South Africa
… design (with the conventional tag data) and Cormack-Jolly-Seber (CJS) models (with the acoustic tag data) to analyze the mark-recapture data. In addition, a von Bertalanffy model was fit to the data to estimate individual growth. The best-fit robust design model showed the population as …

Nesting Ecology Of Red-Headed Woodpeckers (Melanerpes Erythrocephalus) In Central Minnesota
… 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 by sex. Annual apparent survival ranged from …

On the use of demographic models to inform amphibian conservation and management: A case study of the reticulated flatwoods salamander
… their final body size. In chapter 3, we employ a Cormack-Jolly-Seber model, modified to include continuous covariates, to generate size-dependent survival curves. Survival of A bishopi exhibits dramatic annual and seasonal variability, but is always positively correlated with body size. Lastly, in …

Assessing the global conservation status of ecologically poorly undertood, threatened chelonian species : the case of the critically endangered Madagascar spider tortoise (<i>Pyxis arachnoides</i>)
… area of occupancy. A Mark-Capture-Recapture, Cormack-Jolly-Seber model and a stage class, projection matrix was developed to model mean annual survival, finite growth rate and population survival. Finally, remotely sensed habitat loss was monitored within the core of the species range. These …

Population Dynamics of Threatened Piping Plovers on the Niobrara River, Nebraska
… River, 2010–2016, using logistic exposure and Cormack-Jolly-Seber models, respectively. We monitored 1,874 banded hatch-year and adult birds across the regional population (Niobrara River, Lewis and Clark Lake, Gavins Point Reach segment of the Missouri River), and used multi-state …

Management and Mother Nature: piping plover demography and condition in response to flooding on the Missouri River
… model to estimate nest success, a random effects Cormack-Jolly-Seber model in RMARK to estimate pre-fledge chick survival and the Barker model in RMARK to estimate hatch-year (HY) and after hatch-year (AHY) survival and fidelity to our study area. We then used estimates from these analyses to …

Piping Plover (Charadrius melodus) demography, behavior, and movement on the Outer Banks of North Carolina
… used a logistic exposure nest survival model and Cormack-Jolly-Seber model to estimate reproductive success. We uniquely banded 77 adults and 49 chicks to understand annual survival and fidelity rates using a live encounter mark-recapture model. During the pre-fledge period, we observed movements …

Population Dynamics of Piping Plovers (Charadrius melodus) on the Missouri River
… Adult and juvenile survival was calculated using Cormack-Jolly-Seber based models in Program MARK. We used the estimates from these studies to create a matrix population model for piping plovers nesting on the Gavins Point Reach. We used this model to predict the effects of engineered habitat on …

Population Parameter Estimation and Stable Isotope Analysis of Gulf Sturgeon (Acipenser oxyrinchus desotoi) in the Pascagoula River
<p>Gulf Sturgeon (GS), <em>Acipenser oxyrinchus desotoi</em>, are a threatened, anadromous fish species in the northern Gulf of Mexico. Their range is from the Pearl River, LA, in the west to the Suwannee River, FL, in the east with a longitudinal divide at Mobile Bay, AL, creating a western …

Fitness Consequences of Clutch Size Decisions and Mate Change in Black Brant
… the number of goslings leaving the nest and a Cormack-Jolly-Seber mark-recapture analysis to estimate prefledging survival. I found that females breeding with an unfamiliar, but otherwise experienced male fledged at least as many goslings as females breeding with an experienced, familiar mate. …
