Semiparametric Regression in Capture–Recapture Modeling [PDF]

Biometrics, 2006
SummaryCapture–recapture models were developed to estimate survival using data arising from marking and monitoring wild animals over time. Variation in survival may be explained by incorporating relevant covariates. We propose nonparametric and semiparametric regression methods for estimating survival in capture–recapture models.

Newcastle disease virus transmission dynamics in wild peridomestic birds in the United Arab Emirates

Scientific Reports, 2021
To understand the dynamics of a pathogen in an animal population, one must assess how the infection status of individuals changes over time. With wild animals, this can be very challenging because individuals can be difficult to trap and sample, even ...

Connecting the latent multinomial

, 2015
Link et al. (2010) define a general framework for analyzing capture-recapture data with potential misidentifications. In this framework, the observed vector of counts, $y$, is considered as a linear function of a vector of latent counts, $x$, such that ...

Integrating high‐speed videos in capture‐mark‐recapture studies of insects

Ecology and Evolution, 2021
Capture–mark–recapture (CMR) studies have been used extensively in ecology and evolution. While it is feasible to apply CMR in some animals, it is considerably more challenging in small fast‐moving species such as insects.

A comparison of four different methods to estimate population size of Alpine marmot (Marmota marmota) [PDF]

, 2017
Obtaining reliable information on animal abundance in mountainous landscapes is challenging. Highly heterogeneous habitats tend to reduce detection probabilities, and the three-dimensional, rugged nature of the terrain poses severe limits to the ...

Sertraline Treatment Can Mimic Niemann‐Pick Type C Biomarker Profile: A Diagnostic Pitfall

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Background Oxysterols (cholestane‐3β,5α,6β‐triol and 7‐ketocholesterol) and N‐palmitoyl‐O‐phosphocholineserine (PPCS) are sensitive biomarkers for Niemann‐Pick disease type C (NPC) screening. However, false‐positive results occur, with a biomarker profile suggestive of NPC despite the absence of pathogenic variants in genes involved in NPC or ...

Hypercarnivorous apex predator could provide ecosystem services by dispersing seeds [PDF]

, 2016
Large ?hypercarnivorous? felids are recognized for their role as apex predators and hence as key elements in food webs and ecosystem functioning through competition and depredation.

A Mechanistic Blueprint for Fast, High‐Yield Green Scintillators Using Conjugated Polymer–Nanocrystal Composites

Advanced Functional Materials, EarlyView.
Conjugated polymer–nanocrystal composites are investigated to develop fast, high‐yield green scintillators. The polymer F8BT enables efficient, ultrafast emission, while blends with non‐emitting HfO2 nanocrystals and luminescent CdZnS/ZnS quantum dots reveal distinct sensitization mechanisms.

Spatial capture–recapture with random thinning for unidentified encounters

Ecology and Evolution, 2021
Spatial capture–recapture (SCR) models have increasingly been used as a basis for combining capture–recapture data types with variable levels of individual identity information to estimate population density and other demographic parameters.

Capture-Recapture Models [PDF]

BioScience, 1992
nimal ecologists sample the populations they study in a variety of ways. Those who study bird populations in Hawaiian forests may count the number of birds seen and/or heard while walking a transect line or standing at a fixed point in the forest. Those who study red and grey kangaroos in the arid rangelands of central Australia may count animals from ...
