Data from: Night reveals individuality in a shoaling fish

Laura Härkönen, Nico Alioravainen, Anssi Vainikka & Pekka Hyvärinen
Many animals rely heavily on visual cues from their environment, and therefore show circadian rhythmicity in their behavioral activities. In group-living animals, individuals’ activity rhythms must be synchronized not only with diel light-dark cycle but also with other group members. Increasing evidence has recently shown that circadian behaviors of animals are consistent within individuals and different between individuals, but the sources and consistency of diel activity variation in social context are less known. Using radio...

Data from \"Removal of grazers alters the response of tundra soil carbon to warming and enhanced nitrogen availability\", Ecological Monograps in October 2019

Henni Ylänne, Elina Kaarlejärvi, Maria Väisänen, Minna K Männistö, Saija H. K. Ahonen, Johan Olofsson & Sari Stark
Here we present the data used in the manuscript "Removal of grazers alters the response of tundra soil carbon to warming and enhanced nitrogen availability", Ecological Monograps, Early view in October 2019 by H. Ylänne, E. Kaarlejärvi, M. Väisänen, M. K. Männistö, S. H. K. Ahonen, J. Olofsson & S. Stark. In this paper we studied, how five years of experimental warming and increased soil nitrogen availability interact with both long- and short-term differences in...

Data from: Encroachment of shrubs into subalpine grasslands in the Pyrenees modifies the structure of soil fungal communities and soil properties.

The encroachment of shrubs into grasslands is common in terrestrial ecosystems dominated by grass. Land abandonment and favourable climatic trends in recent decades have favoured the expansion of shrubs into subalpine grasslands in many mountainous regions across Europe. The advance of the succession from grassland to shrubland is expected to have a major impact on ecosystem functioning. We used DNA metabarcoding to assess whether the structure of soil fungal communities varied along the succession from...

Catchment properties and the photosynthetic trait composition of freshwater plant communities

Lars Lønsmann Iversen, A. Winkel, L. Baastrup-Spohr, A. B. Hinke, J. Alahuhta, A. Baattrup-Pedersen, S. Birk, P. Brodersen, P. A. Chambers, F. Ecke, T. Feldmann, D. Gebler, J. Heino, T. S. Jespersen, S. J. Moe, T. Riis, L. Sass, O. Vestergaard, S. C. Maberly, K. Sand-Jensen & O. Pedersen
Unlike in land plants, photosynthesis in many aquatic plants relies on bicarbonate in addition to carbon dioxide (CO2) to compensate for the low diffusivity and potential depletion of CO2 in water. Concentrations of bicarbonate and CO2 vary greatly with catchment geology. In this study, we investigate whether there is a link between these concentrations and the frequency of freshwater plants possessing the bicarbonate use trait. We show, globally, that the frequency of plant species with...

Genetic assignment of individuals to source populations using network estimation tools

Markku Kuismin, Dilan Saatoglu, Alina Niskanen, Henrik Jensen & Mikko Sillanpää
Dispersal, the movement of individuals between populations, is crucial in many ecological and genetic processes. However, direct identification of dispersing individuals is difficult or impossible in natural populations. By using genetic assignment methods, individuals with unknown genetic origin can be assigned to source populations. This knowledge is necessary in studying many key questions in ecology, evolution and conservation. We introduce a network-based tool BONE (Baseline Oriented Network Estimation) for genetic population assignment, which borrows concepts...

Data for: Phytochemical shift from condensed tannins to flavonoids in transgenic Betula pendula decreases consumption and growth but improves growth efficiency of Epirrita autumnata larvae

Paula Thitz, Lauri Mehtätalo, Panu Välimäki, Tendry Randriamanana, Mika Lännenpää, Ann E. Hagerman, Tommi Andersson, Riitta Julkunen-Tiitto & Tommi Nyman
Despite active research, antiherbivore activity of specific plant phenolics remains largely unresolved. We constructed silver birch (Betula pendula) lines with modified phenolic metabolism to study the effects of foliar flavonoids and condensed tannins on consumption and growth of larvae of a generalist herbivore, the autumnal moth (Epirrita autumnata). We conducted a feeding experiment using birch lines in which expression of dihydroflavonol reductase (DFR), anthocyanidin synthase (ANS) or anthocyanidin reductase (ANR) had been decreased by RNA...
