The average laboratory samples a population of 7,300 Amazon Mechanical Turk workers [PDF]

open access: yes, 2015
Using capture-recapture analysis we estimate the effective size of the active Amazon Mechanical Turk (MTurk) population that a typical laboratory can access to be about 7,300 workers.

Physiology and Survival of Intertidal Calcifiers in Two Contrasting Upwelling Systems

open access: yesEcology and Evolution, Volume 16, Issue 2, February 2026.
This study evaluates the physiological responses and survival of two intertidal mollusk species, Chiton granosus and Scurria zebrina, across contrasting upwelling environments. We found that metabolic rates and survival differ between populations exposed to seasonal versus semi‐permanent upwelling.

Status and population dynamics of the Critically Endangered Valcheta frog Pleurodema somuncurense on the Patagonian Somuncura Plateau

open access: yesEndangered Species Research, 2019
Amphibian populations are declining globally. In this scenario, detailed information on their ecology is crucial to determine the status and extinction risk of their populations and, therefore, better plan conservation activities.

First Direct Evidence for Natal Wintering Ground Fidelity and Estimate of Juvenile Survival in the New Zealand Southern Right Whale Eubalaena australis. [PDF]

open access: yesPLoS ONE, 2016
Juvenile survival and recruitment can be more sensitive to environmental, ecological and anthropogenic factors than adult survival, influencing population-level processes like recruitment and growth rate in long-lived, iteroparous species such as ...

Trap‐dependence in capture–recapture studies: empirical evidence in vertebrates and biological meaning

open access: yesOikos, Volume 2026, Issue 2, February 2026.
Capture–recapture (CR) models have been used for decades to estimate population size and demographic rates in natural populations from the monitoring of individuals. One of the most frequent deviations from assumptions required in CR studies is the immediate trap‐dependence that corresponds to the correlation between capture events. We review empirical

A new strategy for diagnostic model assessment in capture-recapture [PDF]

open access: yes, 2016
Common to both diagnostic tests used in capture–recapture and score tests is the idea that starting from a simple base model it is possible to interrogate data to determine whether more complex parameter structures will be supported.

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 ...

The fishing and natural mortality of large, piscivorous Bull Trout and Rainbow Trout in Kootenay Lake, British Columbia (2008–2013) [PDF]

open access: yesPeerJ, 2017
Background Estimates of fishing and natural mortality are important for understanding, and ultimately managing, commercial and recreational fisheries.

A range‐wide full‐annual‐cycle model informs conservation of a declining migratory shorebird

open access: yesJournal of Applied Ecology, Volume 63, Issue 1, January 2026.
The tōrea population decline suggests the need for a higher IUCN threat classification and a conservation strategy (e.g. habitat protection and restoration) targeting multiple demographic rates across the annual cycle of tōrea. Our novel approach using population growth rates to link fragmented local, season‐specific data to model range‐wide full ...
