Migration speed, timing, and long‐term shifts in age structure in North American passerines during fall migration

open access: yesEcography, EarlyView.
Migration is challenging for birds, especially juveniles, who experience high mortality rates during migration. The challenge is exacerbated in the Anthropocene, contributing to widespread population declines. Conservation efforts focused on increasing juvenile survival could bolster population recovery.

Estimating the prevalence of drug use using mark-recapture methods [PDF]

open access: yes
Sparked by the need to inform the response to the spread of HIV/AIDS in drug injecting populations in the 1980s and the desire to base local, national and international responses to tackling drug use in the 1990s on solid epidemiological data, the mark ...

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

open access: yesKnowledge 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 ...

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

open access: yesNature 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 ...

Active dispersal of Aedes albopictus: a mark-release-recapture study using self-marking units

open access: yesParasites & Vectors, 2019
Understanding the dispersal dynamics of invasive mosquito species is fundamental to improve vector surveillance and to target control efforts. Aedes albopictus has been deemed a poor flyer as its range of active dispersal is generally assumed to be ...

Mastery Exams: Giving Students a Second Opportunity to Demonstrate Understanding

open access: yesJournal of Dental Education, EarlyView.
ABSTRACT Various stressors can affect student exam performance, and a single weak result may not reflect true understanding. To address this, a “Mastery” exam policy was introduced in the 2021–2022 academic year. If a student scores below 80% on a didactic or pre‐clinical laboratory exam worth at least 10% of their final course grade, they can choose ...

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

open access: yesKoedoe: 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 ...
