Phenological time lapse images from ground camera MC128 in Kaamanen Peatland
, 2020 This record contains phenological time lapse images from camera Kaamanen Peatland. Camera was mounted at ground view level at location 69.140583;27.269817(N;E, WGS84). First set of images were taken between 25.03.2015--31.12.2016 (Version 1). Subsequent

Phantasmic Encounters in the Arctic: Haunting Materialities Beyond the Ghosts of War
Anthropology of Consciousness, Volume 37, Issue 1, Spring 2026.ABSTRACT In the vast north, ghostly experiences are common for locals and outsiders alike. Here, we explore how cultural‐natural attributes, like remoteness and extreme seasonal variation, compound experiences of the haunting in visceral ways. This provides the Arctic region with an unusually pronounced baseline of other‐than‐human agency, which in the

Rangifer, 1996 To find out if timing of endectocidic antiparasitic treatment is critical for its efficacy in overwintering reindeer, 72 hinds of the Kaamanen Experimental Reindeer Herd were randomly allocated to four groups.

Diel variation in CO2 flux is substantial in many lakes
Limnology and Oceanography Letters, Volume 10, Issue 6, Page 977-989, December 2025.Abstract Lakes play a significant role in the global carbon cycle, acting as sources and sinks of carbon dioxide (CO2). In situ measurements of CO2 flux (FCO2) from lakes have generally been collected during daylight, despite indications of significant diel variability.

Variability in Trends and Indicators of CO2 Exchange Across Arctic Wetlands
Journal of Geophysical Research: Biogeosciences, Volume 124, Issue 5, Page 1248-1264, May 2019., 2019 Abstract Arctic wetlands store nearly half of the world's soil organic carbon and are crucial to the global carbon cycle. However, most Earth system models fail to account for wetlands given heterogeneity and uncertainty surrounding the response of different wetland types to climate change. We analyzed summer (June–August) carbon dioxide (CO2) exchange,

Reproductive investment by females in semi-domesticated reindeer
Rangifer, 1990 This paper discusses maternal investment in a herd of semi-domesticated reindeer in Kaamanen, Finnish Lapland (69°N 27°E). Male-producing cows weighed 2% more at the previous conception then the female-producing cows did. The body weight of cow accounted

Year‐Round δ13C‐CH4 Reveals Seasonal Transition in Methane‐Related Processes in a Boreal Mire
Journal of Geophysical Research: Biogeosciences, Volume 130, Issue 9, September 2025.Abstract While boreal mires are known to be a significant natural source of methane (CH4), the seasonality of the related processes and their controls are still poorly understood. Here we aim to characterize CH4 production, oxidation and transport, and their drivers in a boreal mire using year‐round continuous measurements of stable carbon isotope ...

The Impact of Parametric Uncertainties on Biogeochemistry in the E3SM Land Model
Journal of Advances in Modeling Earth Systems, Volume 10, Issue 2, Page 297-319, February 2018., 2018 Abstract We conduct a global sensitivity analysis (GSA) of the Energy Exascale Earth System Model (E3SM), land model (ELM) to calculate the sensitivity of five key carbon cycle outputs to 68 model parameters. This GSA is conducted by first constructing a Polynomial Chaos (PC) surrogate via new Weighted Iterative Bayesian Compressive Sensing (WIBCS ...

Journal of Geophysical Research: Biogeosciences, Volume 130, Issue 5, May 2025.Abstract Peatlands are important climate change mitigation agents as they store large amounts of carbon (C). Yet, their C sink capacity is vulnerable to environmental changes, which is however uncertain in a changing climate. Here, we examined potential habitat‐specific C accumulation drivers over the past ∼1,000 years, using replicate peat records ...

Sex ratio variation in reindeer Rangifer tarandus: a test of the extrinsic modification hypothesis
Wildlife Biology, Volume 9, Issue 1, Page 29-36, March 2003., 2003 Evolutionary theories based on adaptive modification of maternal investment are generally suggested to explain variation in offspring sex ratios, but general concordance with empirical data is rare. Recently, factors beyond the control of the mother, such as density and climate, were reported to affect offspring sex ratios, and the extrinsic ...
