A capture–recapture framework for combining biologging data with physical captures to decompose and estimate demographic rates: Simulations across life cycles and application to polar bears

open access: yesMethods in Ecology and Evolution, EarlyView.
Abstract Estimating demographic rates of wild populations is critical to understanding their dynamics but can be challenging because large amounts of data are required, and parts of the life cycle of individuals may be unobserved. In numerous research programmes, capture–recapture (CR) data and biologging data are collected in parallel.

Estimating spatiotemporal reproductive dynamics of fish populations with passive acoustic monitoring: A state‐space model approach

open access: yesMethods in Ecology and Evolution, EarlyView.
Abstract Passive acoustic monitoring (PAM) has been used to estimate the presence and spatial distribution of target organisms using biological sounds received by microphones. Due to its cost‐effectiveness and non‐invasiveness, PAM is becoming a promising approach for studying the spatiotemporal dynamics of large groups in response to environmental ...

A dynamic multi‐scale occupancy model to estimate trends in habitat use in spatially and temporally complex systems

open access: yesMethods in Ecology and Evolution, EarlyView.
Abstract Species occurrence is often influenced by changes in environmental conditions at multiple spatial and temporal scales working simultaneously in a hierarchical fashion. While previous dynamic multi‐scale occupancy modelling frameworks address dynamics at multiple spatial scales, they assume both large‐scale and small‐scale units are closed ...

Addressing ecological challenges from a quantum computing perspective

open access: yesMethods in Ecology and Evolution, EarlyView.
Abstract With increased access to data and the advent of computers, the use of statistical tools and numerical simulations is becoming commonplace for ecologists. These approaches help improve our understanding of ecological phenomena and their underlying mechanisms in increasingly complex environments.
