Whole Lake Behaviour of Sea‐Run Brown Trout During Pre‐Spawning Months

open access: yesEcology of Freshwater Fish, Volume 34, Issue 4, October 2025.
ABSTRACT Sea‐run brown trout use lake habitat extensively when it is available both before and after spawning. However, the ways in which brown trout actually use lakes remain poorly resolved. In Norway, some of these lakes are used as reservoirs for the effluent of high‐head power stations that tunnel mountain water through turbines, discharging the ...

Passive Positioning Using Linear Multilateration

open access: yes, 2023
Passive localization of aircraft in flight using signal time of arrival (TOA) poses some unique challenges. The sensors must be deployed in an approximately coplanar configuration, which produces significant vertical uncertainty in the estimated position.

Tracking large bees in open landscapes with active radio tags—Advantages and challenges using stationary receivers

open access: yesJournal of Animal Ecology, Volume 94, Issue 9, Page 1638-1649, September 2025.
Studying the spatial ecology of ecologically relevant species supports the development of effective conservation strategies. Recent technological advancements in remote tracking methods now enable researchers to study large flower‐visiting insects and important pollinators, such as carpenter bees.

Automatic detection for bioacoustic research: a practical guide from and for biologists and computer scientists

open access: yesBiological Reviews, Volume 100, Issue 2, Page 620-646, April 2025.
ABSTRACT Recent years have seen a dramatic rise in the use of passive acoustic monitoring (PAM) for biological and ecological applications, and a corresponding increase in the volume of data generated. However, data sets are often becoming so sizable that analysing them manually is increasingly burdensome and unrealistic. Fortunately, we have also seen
