Imagining the next pandemic: Finnish preparedness for chronic transboundary crises before and during COVID‐19

open access: yesRisk, Hazards &Crisis in Public Policy, Volume 14, Issue 3, Page 226-246, September 2023., 2023
Abstract Before the COVID‐19 pandemic, infectious disease experts had postulated that the next pandemic is only a matter of time, and Finland, among other nations, had prepared for it. Yet the COVID‐19 pandemic crossed the customary political, functional, and temporal boundaries of crisis management to a surprising degree.

Continuous on‐board behaviour classification using accelerometry: A case study with a new GPS‐3G‐Bluetooth system in Pacific black ducks

open access: yesMethods in Ecology and Evolution, Volume 13, Issue 7, Page 1429-1435, July 2022., 2022
Abstract Over the past two decades, accelerometer (ACC) data have been increasingly used to study animal behaviours and energetics. However, the large amount of raw ACC data can be a burden to device storage and power consumption and in many cases may also require device retrieval for data collection.

Evaluating the social and ecological effectiveness of partially protected marine areas

open access: yesConservation Biology, Volume 35, Issue 3, Page 921-932, June 2021., 2021
Abstract Marine protected areas (MPAs) are a primary tool for the stewardship, conservation, and restoration of marine ecosystems, yet 69% of global MPAs are only partially protected (i.e., are open to some form of fishing). Although fully protected areas have well‐documented outcomes, including increased fish diversity and biomass, the effectiveness ...
