Balancing Fire Regimes and Population Dynamics for the Conservation of a Microendemic Lizard From a Biodiversity Hotspot

Animal Conservation, EarlyView.
Disturbance from fire mediates a potential ecophysiological trade‐off between adult performance and juvenile recruitment in the microendemic lizard Ameivula jalapensis. While open, burned habitats enhance adult thermoregulation and condition, unburned patches remain critical for juvenile thermal optima.

Microbiome Dynamics During Translocation of the Critically Endangered Frog Craugastor ranoides

Animal Conservation, EarlyView.
A female Craugastor ranoides fitted with an LB‐2X radio transmitter using a silicone waist‐belt harness for post‐translocation monitoring. ABSTRACT Amphibian populations are declining, and species are going extinct due to habitat loss, climate change, and emerging infectious disease, prompting the increasing use of translocations as a conservation tool.

Human Recreation and Fire History Shape Landscape Connectivity for an Endangered Forest Carnivore

Animal Conservation, EarlyView.
Roads and trails can impede wildlife movement, but their permeability varies with human use and fire history. We combined GPS telemetry from 45 endangered southern Sierra Nevada fishers (Pekania pennanti) with smartphone‐derived human mobility data to estimate crossing probability across road and trail segments. Fishers were about 2.5 times more likely

Running towards: Labour market incentives for runaway slaves in the British Cape Colony, 1830–1838

Asia‐Pacific Economic History Review, EarlyView.
Abstract Recent scholarship on slave escapes has increasingly emphasised economic motivation, but few studies have empirically investigated how market incentives influenced the decision‐making of enslaved individuals during transitions from coerced to wage labour.

Coerced labour patterns in the Cape Colony, c. 1806–1826

Asia‐Pacific Economic History Review, EarlyView.
Abstract Multiple forms of coerced labour co‐existed in the early 19th‐century Cape Colony. This study examines changes in coerced labour force composition. Using annual taxation and census records, we examine district‐ and household‐level changes in reported enslaved, Recaptured African and indigenous Khoesan labour.

Capture‐recapture

American Ethnologist, 2022
ABSTRACTCapture‐recapture, a method devised for estimating wildlife population sizes using technologies like bird banding, has been repurposed for use with “rare and elusive” human populations. Capture‐recapture is implemented to count “key populations,” groups that constitute a small portion of the general population but are at high risk of HIV ...

A Bayesian, combinatorial approach to capture–recapture

Theoretical Population Biology, 2006
It is shown that, in the capture-recapture method, the widely used formulae of Bailey or Chapman-Seber give the most likely value for the size of the population, but systematically underestimate the probability that the population is larger than any given size.

Capture-recapture modelling [PDF]

, 2012
The chapter describes capture-recapture modelling in the context of TB incidence estimation. Familiarity with the R computing language will help to follow the example. The chapter is intended primarily for epidemiologists and statisticians who are involved in or have an interest in inventory ...

Capture-Recapture Models

Journal of the American Statistical Association, 2000
Here I briefly review capture-recapture models as they apply to estimation of demographic parameters (e.g., population size, survival, recruitment, emigration, and immigration) for wild animal populations. These models are now also widely used in a variety of other applications, such as the census undercount, incidence of disease, criminality ...

Capture–recapture methods

1998
The capture-recapture methods have been long studied and applied in ecology and wildlife management [34]. In order to estimate the number of animals in a closed or open population, a sample of n 1 animals is taken from the population, the animals are marked or tagged for future identification and then returned to the population. After allowing time for
