Elasmobranch Mark–Recapture Experiment off the Balearic Islands: Insight into Scyliorhinus canicula Growth, Mobility, and Population Size

Fishes
Despite the high diversity of elasmobranch fishes in the Balearic Islands, knowledge of their biology and population dynamics is still scarce. A recent mark-and-recapture experiment off the Balearic Islands tagged 3738 individuals of 23 shark and batoid ...

Growth of the purple snail Plicopurpura pansa in Baja California Sur, Mexico

Ciencias Marinas, 2003
 To study the growth of the purple snail Plicopurpura pansa at the northern limit of its distribution, from 1999 to 2001 monthly random samples were obtained from two beaches in the southern part of the Baja California Peninsula (Mexico): one on the ...

Reliability of catch per unit effort (CPUE) for evaluation of reintroduction programs – A comparison of the mark-recapture method with standardized trapping

Knowledge and Management of Aquatic Ecosystems, 2011
Catch per unit effort (CPUE) is used as a standardized trapping method by local fishermen and in monitoring studies. In this study, CPUE was compared with population estimates made with a capture-recapture method based on the passive ...

An integrated model improves inferences about survival in the Mojave desert tortoise

Endangered Species Research
The Mojave desert tortoise Gopherus agassizii experienced population declines during recent decades, which have persisted despite its designation as a federally protected species.

Mark-release-recapture experiment in Burkina Faso demonstrates reduced fitness and dispersal of genetically-modified sterile malaria mosquitoes

Nature Communications, 2022
Release of genetically-modified sterile mosquitoes is a potential method of malaria control but has yet to be tested in the field. Here, the authors perform a mark-release-recapture experiment and show that genetically-modified mosquitoes have reduced ...

More information from the mark and recapture of fish at Kosi Bay, South Africa

Koedoe: African Protected Area Conservation and Science, 2002
A considerable amount of work has been carried out on the mark and recapture of fish at Kosi bay (Kyle 1986). This resulted in the publication of data (Kyle & Robertson 1997) suggesting fairly low rates of exploitation by man but warning that further ...

The development and evaluation of a self-marking unit to estimate malaria vector survival and dispersal distance

Malaria Journal, 2019
Background A clear understanding of mosquito biology is fundamental to the control efforts of mosquito-borne diseases such as malaria. Mosquito mark-release-recapture (MMRR) experiments are a popular method of measuring the survival and dispersal of ...

Estimating effective population size using close‐kin mark–recapture

Methods in Ecology and Evolution
Close‐kin mark–recapture (CKMR) is a method that allows estimating population census size, among other parameters, through the observed number of pairs that are close‐kin including parent–offspring pairs (POPs) and half‐sibling pairs (HSPs).

Individual heterogeneity and identifiability in capture-recapture models [PDF]

Animal Biodiversity and Conservation, 2004
Individual heterogeneity in detection probabilities is a far more serious problem for capture-recapture modeling than has previously been recognized.

Age‐specific survival of reintroduced swift fox in Badlands National Park and surrounding lands

Wildlife Society Bulletin, 2016
In 2003, a reintroduction program was initiated at Badlands National Park (BNP), South Dakota, USA, with swift foxes (Vulpes velox) translocated from Colorado and Wyoming, USA, as part of a restoration effort to recover declining swift fox populations ...
