Using acoustic monitoring to reveal nearly year‐round presence of humpback whales (Megaptera novaeangliae) in the waters of southern Iceland

open access: yesMarine Mammal Science, Volume 41, Issue 2, April 2025.
Abstract Icelandic waters are a crucial feeding ground for North Atlantic humpback whales, yet their occurrence in these subarctic waters remains underexplored. This study examined seasonal and diel patterns in humpback whale occurrence off the Vestmannaeyjar archipelago, southern Iceland, from June 2018 to May 2019, using automated acoustic detections

Effectiveness of mass marking of juvenile sterlet (Acipenser ruthenus) with alizarin red S stain on field detection

open access: yesFisheries Management and Ecology, Volume 32, Issue 1, February 2025.
Abstract Sterlet (Acipenser ruthenus), one of the last sturgeons in the Danube basin, is regularly stocked in national and international restoration programs, but the efficacy of stocking has not yet been evaluated. Effectiveness of stocking should involve marking and evaluating growth and survival of juveniles.

A wireless, remotely operable and easily customizable robotic flower system

open access: yesMethods in Ecology and Evolution, Volume 15, Issue 8, Page 1312-1324, August 2024.
Abstract Understanding the complex interactions between external and internal factors that influence pollinator foraging behaviour is essential to understand ecosystem functioning, design agricultural practices or develop effective conservation strategies. However, it remains challenging to collect large and reliable data sets with reasonable personnel

Evaluating harvest incentives for suppressing a socially‐valued, but ecologically‐detrimental, invasive fish predator

open access: yesFisheries Management and Ecology, Volume 31, Issue 4, August 2024.
Abstract The legacy of intentional freshwater fish introductions across the western United States has fostered social tensions over the control of nonnative species in some contexts. Overcoming tensions and implementing effective control programs is important for mitigating impacts to native species.

Pollinator‐assisted plant phenotyping, selection, and breeding for crop resilience to abiotic stresses

open access: yesThe Plant Journal, Volume 119, Issue 1, Page 56-64, July 2024.
SUMMARY Food security is threatened by climate change, with heat and drought being the main stresses affecting crop physiology and ecosystem services, such as plant–pollinator interactions. We hypothesize that tracking and ranking pollinators' preferences for flowers under environmental pressure could be used as a marker of plant quality for ...
