The estimation of grizzly bear density through hair‐snagging techniques above the tree line

Wildlife Society Bulletin, 2015
Assessing grizzly bears' (Ursus arctos) abundance in the Arctic has been challenging because of the large scale of their movements and the remoteness of field locations.

Challenges and opportunities for monitoring wild Nile crocodiles with scute mark-recapture photography

Koedoe: African Protected Area Conservation and Science, 2018
The global conservation status of Nile crocodiles (Crocodylus niloticus) was last assessed in 1996. The species presents particular difficulty in monitoring because it can be cryptic, require expertise to handle, and caudal tail tags and transmitters are

‘Self’ and ‘othering’ as a byproduct of large‐scale assessment: An investigation into the Gaokao retake policy

British Educational Research Journal, EarlyView.
Abstract While Gaokao, the National College Entrance Examination (NCEE), has been extensively discussed outside the Chinese academic circle, the retake policy of the test has not received much attention. Moreover, Gaokao research in China has predominantly examined the effectiveness of the retake decision in relation to students' demographic ...

The Use of Mixture Models in Capture-Recapture [PDF]

, 2015
Mixture models have been widely used to model heterogeneity. In this thesis, we focus on the use of mixture models in capture--recapture, for both closed populations and open populations. We provide both practical and theoretical investigations.

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 ...

On the identifiability of the trinomial model for mark‐recapture‐recovery studies

Environmetrics, 2023
AbstractContinuous predictors of survival present a challenge in the analysis of data from studies of marked individuals if they vary over time and can only be observed when individuals are captured. Existing methods to study the effects of such variables have followed one of two approaches. The first is to model the joint distribution of the predictor

Knowledge gaps and research directions in migration ecology for advancing the conservation of migratory songbirds

Biological Reviews, EarlyView.
ABSTRACT Understanding migration ecology is essential for effective conservation of migratory species. To achieve a comprehensive understanding of the ecology of migrating species, it is necessary to study how species react to the complex interplay of intrinsic and extrinsic conditions when optimizing their migratory journey in terms of survival ...

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 ...
