Efficient estimation of large‐scale spatial capture–recapture models

Ecosphere, 2021
Capture–recapture methods are a common tool in ecological statistics, which have been extended to spatial capture–recapture models for data accompanied by location information.

Implementation of the E×B and Grad‐B Drift in the EMC3 Code and Verification Using the Method of Manufactured Solutions

Contributions to Plasma Physics, EarlyView.
ABSTRACT Effective management of particle and power exhaust is essential for fusion reactor operation, requiring accurate 3D modeling of divertor physics. The EMC3 code is a well‐established Monte Carlo tool for plasma transport in stellarator edge regions, but until now lacked E×B$$ E\times B $$ and diamagnetic drifts.

Changes in capture availability due to infection can lead to detectable biases in population-level infectious disease parameters [PDF]

PeerJ
Correctly identifying the strength of selection that parasites impose on hosts is key to predicting epidemiological and evolutionary outcomes of host-parasite interactions. However, behavioral changes due to infection can alter the capture probability of

Climate‐driven resource availability drives medium‐ and broad‐scale temporal changes in owl–prey interactions over 24 years in a semi‐arid ecosystem

Ecography, EarlyView.
Predator–prey interactions are vital to ecosystem functioning but may be disrupted by climate change. We investigated a food‐web network involving three owl species over 24 years in a semi‐arid ecosystem at Bosque Fray Jorge National Park, Chile.

Enforced but not Enacted: How Return‐to‐Office Policies Reshape Boundary Enactment, Work‐Location Volition, and Eudaimonic Wellbeing

Human Resource Management, EarlyView.
ABSTRACT HR faces a conundrum over how to organize hybrid working patterns given the pros and cons associated with conducting work across multiple domains. Many organizations are currently seeking to clarify and often increase the requirements for employee presence at employer premises, meaning studies are needed to better understand how HR should look

Can the Parallel or Tandem Combination of Questionnaire‐Based Risk Assessment and Fecal Immunochemical Test Improve the Efficiency of Colorectal Cancer Screening?

International Journal of Cancer, EarlyView.
Colorectal cancer screening reduces disease burden, but the comparative performance of screening strategies remains unclear. This population‐based study shows that the tandem strategy (positive results from both questionnaire‐based risk assessment and fecal immunochemical testing) substantially improved the detection rates of colorectal cancer and ...

The Effect of Age on Survival Is Similar in Males and Females of an Aquatic Insect Species

Ecologies
Age is a critical intrinsic factor that influences the probability of survival of organisms on Earth. In many animals, the lifestyles and habitat occupancy of males and females are so different that the effect of age could be sex-dependent.

Long-term trends in the use of a protected area by small cetaceans in relation to changes in population status

Global Ecology and Conservation, 2014
The requirement to monitor listed species in European designated sites is challenging for long-lived mobile species that only temporarily occupy protected areas.

Population size estimates based on the frequency of genetically assigned parent–offspring pairs within a subsample

Ecology and Evolution, 2020
Estimating population density as precise as possible is a key premise for managing wild animal species. This can be a challenging task if the species in question is elusive or, due to high quantities, hard to count.

Capture-mark-recapture analysis reveals survival correlates in Salamandrina perspicillata (Savi, 1821)

Amphibia-Reptilia, 2010
AbstractWe carried out a mark-recapture survival analysis of female Salamandrina perspicillata in two central Italian populations. Overall survival was similar in both populations (about 85-90% per year) and the estimated lifespan was about twelve years.
