Mark-recapture vs. line-transect abundance estimates of a coastal dolphin population: a case study of Tursiops truncatus from Laguna, southern Brazil

open access: yes, 2017
Cetacean populations in coastal habitats are increasingly threatened by multiple anthropogenic impacts. Monitoring these populations to obtain robust estimates of abundance and detect trends over time is critical to achieve conservation goals.

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 ...

Estimating effective population size using close‐kin mark–recapture

open access: yesMethods 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).

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

open access: yesMalaria 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 ...
