An Evaluation of Population Restoration and Monitoring Techniques for Freshwater Mussels in the Upper Clinch River, Virginia, and Refinement of Culture Methods for Laboratory-Propagated Juveniles
… in 2011 and 2012 by systematic quadrat and capture-mark-recapture sampling to assess reintroduction success, evaluate reintroduction techniques, and compare survey approaches for monitoring freshwater mussels. Estimates of abundance and density of translocated adults ranged from 450-577 …

Searching for answers to the silent decline: first estimates of survival and recruitment for the critically endangered Rose's mountain toadlet, Capensibufo rosei
… and recruitment rates for the species, using Capture-Mark-Recapture (CMR) methods, over a 7-year period, in order to identify demographic trends over time. I also used covariate models to test whether any observed trends in these demographic parameters were significantly related to variation …

Ornate box turtle (Terrapene ornata) demography in northern Illinois
… To estimate annual survival, I conducted capture-mark-recapture surveys. Annual apparent survival was 0.970 at Ayers Sand Prairie and 0.860 at Nachusa Grasslands. Matrix population models showed the Ayers Sand Prairie population as stable, whereas the Nachusa Grasslands population was in …

Demography of the spotted turtle (clemmys guttata) in Illinois
… supplementing an existing dataset by conducting capture-mark-recapture in 2015–2016. I used the subsequent capture and reproductive data spanning 1988–2016 and Package RMark to analyze deterministic measures of change for both populations. Both populations exhibited an even sex ratio, a strong …

Tales of an 'invisible' life stage : survival and physiology among terrestrial juvenile Ambystomatid salamanders
… and A. texanum) by conducting an 11-month capture-mark recapture study within semi-natural enclosures. I found juvenile survival rates to be constant through time and comparable among species. These similarities indicated that vital rate estimates from congeneric, ecologically similar …

An assessment of coping strategies in the marketing of produce by street vendors
… elevation in the Soutpanberg Mountains. Capture mark recapture method was conducted at five altitudinal sites ranging from 1000-174 7m above sea level in the southern slopes of the western Soutpansberg. Data on different environmental variables (Microhabitat and climate) were collected. …

Predator Behavior and Prey Demography in Patchy Habitats
… of Masticophis flagellum (Coachwhip) using capture-mark-recapture and radio telemetry techniques. I also examined the influence of saurophagous snake abundance on the survival rate of Sceloporus woodi (Florida Scrub Lizard) populations. Masticophis flagellum positively selected lizard and …

EFFECT OF COVER ON SMALL MAMMAL ABUNDANCE AND MOVEMENT THROUGH WILDLIFE UNDERPASSES
… served as control with no cover added. Capture-mark-recapture using live traps was conducted in the fall of 2012 to record abundance and movement of small mammals in and around the underpasses. There was no statistically significant effect of cover on small mammal abundance detected by …

Population Dynamics of Ouachita Dusky Salamanders (Desmognathus brimleyorum) in a Managed Forest Landscape
… shifts, survival and movement. We conducted a capture-mark-recapture (CMR) study at three streams within intensely managed pine forests in west-central Arkansas from May 2014-October 2016. The pine stands surrounding two of the streams were harvested following state Best Management Practices …

Amphibian and Reptile Community Responses to Forest and Riparian Disturbance
… (Desmognathus brimleyorum). We used intensive capture-mark-recapture at three headwater streams embedded in intensely managed pine forests of west-central Arkansas, employing a Before-After-Control-Impact (BACI) design. Collectively, our results indicate that SMZs surrounding small first-order …

Microhabitat requirements of the great crested newt (<i>Triturus cristatus</i>) in a woodland area
… which is situated to the north-east of London. Capture-mark-recapture of adults in four ponds over 5 years within a 1 km area revealed that great crested newts exhibited large fluctuations in detection probabilities, highlighting the importance of calculating detection before making inferences …

Human-turtle interactions during freshwater recreational activities: Understanding risks and mitigation strategies
… Lake, Rideau Canal Waterway using two methods - capture-mark-recapture and local ecological knowledge. We found differing results from both methods. We suspect ongoing research from the lake’s biological station influenced local knowledge, awareness, and perceptions of turtles, revealing insights …

The use of ringing data in the study of climatic influences on common passerines
… baeticatus (an azonal wetland specialist) a capture-mark-recapture model correlated higher temperature in the breeding grounds with higher adult survival (1998-2010), but - contrary to expectations - not wetter winters. A spatial analysis using a multi-state model in a Bayesian framework did …
