Data from: Mosaic metabolic ageing: Basal and standard metabolic rate age in opposite directions and independent of environmental quality, sex and lifespan in a passerine

Michael Briga & Simon Verhulst
1. Crucial to our understanding of the ageing process is identifying how traits change with age, which variables alter their ageing process and how these traits associate with fitness. 2. Here we investigated metabolic ageing in outdoor-living captive zebra finches experiencing foraging costs. We longitudinally monitored 407 individuals over six years and collected 3213 measurements of two independent mass-adjusted metabolic traits: basal metabolic rate (BMRm) at thermoneutral temperatures and standard metabolic rate (SMRm), measured as...

Data for: Female-biased sex ratios in urban centres create a fertility trap in post war Finland

Jenni Pettay
Because sex ratios are a key factor regulating mating success and subsequent fitness both across and within species, there is widespread interest in how population-wide sex ratio imbalances affect marriage markets and the formation of families in human societies. Although most modern cities have more women than men and suffer from low fertility rates, the effects of female-biased sex ratios have garnered less attention than male-biased ratios. Here, we analyze how sex ratios are linked...

Microsatellite data of Vincetoxicum hirundinaria offspring and their inferred mother plants from 13 populations in the South-Western Finnish Archipelago

Anne Muola, J. F. Scheepens, Liisa Laukkanen, Aino Kalske, Pia Mutikainen & Roosa Leimu
Fragmented landscapes may have implications for the genetic structure of populations and for the microevolution of plant species. In particular, landscape fragmentation and/or population isolation might affect the evolution of plant mating systems. Here, we study the consequences of landscape fragmentation on the genetic structure of populations of a perennial herb, Vincetoxicum hirundinaria with a mixed mating system. Our study area, the south-western Finnish archipelago, was formed after the glacial ice sheet started to retreat...

Data for: Parasitoids indicate major climate-induced shifts in Arctic communities

Tuomas Kankaanpää, Eero Vesterinen, Bess Hardwick, Niels Martin Martin Schmidt, Tommi Andersson, Paul Eric Aspholm, Isabel Barrio, Niklas Beckers, Joël Bêty, Tone Birkemoe, Melissa DeSiervo, Katherine Drotos, Dorothee Ehrich, Olivier Gilg, Vladimir Gilg, Nils Hein, Toke Høye, Kristian Jakobsen, Camille Jodouin, Jesse Jorna, Mikhail Kozlov, Jean-Claude Kresse, Don-Jean Leandri-Breton, Nicolas Lecomte, Maia Olsen … & Tomas Roslin
Climatic impacts are especially pronounced in the Arctic, which as a region is warming twice as fast as the rest of the globe. Here, we investigate how mean climatic conditions and rates of climatic change impact parasitoid insect communities in 16 localities across the Arctic. We focus on parasitoids in a wide-spread habitat, Dryas heathlands, and describe parasitoid community composition in terms of larval host use (i.e. parasitoid use of herbivorous Lepidoptera versus pollinating Diptera)...

Phototactic choices of Drosophila melanogaster

When organisms' environmental conditions vary unpredictably in time, it can be advantageous for individuals to hedge their phenotypic bets. It has been shown that a bet-hedging strategy underlies the high inter-individual diversity of phototactic choice in Drosophila melanogaster. This study shows that fruit flies from a population living in a boreal and relatively unpredictable climate had more variable phototactic choices than fruit flies from a more stable tropical climate, consistent with bet-hedging theory. We experimentally...
