Functional diversity and invasive species influence soil fertility in experimental grasslands
(Peer reviewed; Journal article, 2020-01-01)Ecosystem properties can be positively affected by plant functional diversity and compromised by invasive alien plants. We performed a community assembly study in mesocosms manipulating different functional diversity levels ... -
Fundamental resource specialization of herbivorous butterflies decreases towards lower latitudes
(Peer reviewed; Journal article, 2021-08-17)Aim It is generally assumed that the degree of resource specialization in herbivorous insects increases towards lower latitudes. However, latitudinal patterns in herbivore diet breadth at large spatial scales remain poorly ... -
Gap-filling continuously-measured soil respiration data: A highlight of time-series-based methods
(Peer reviewed; Journal article, 2020-05-15)Soil respiration is an important ecosystem process that releases carbon dioxide into the atmosphere. While soil respiration can be measured continuously at high temporal resolutions, gaps in the dataset are inevitable, ... -
Genetic analysis indicates spatial-dependent patterns of sex-biased dispersal in Eurasian lynx in Finland
(Peer reviewed; Journal article, 2021-02-19)Conservation and management of large carnivores requires knowledge of female and male dispersal. Such information is crucial to evaluate the population’s status and thus management actions. This knowledge is challenging ... -
