Data from: Widespread introgression of mountain hare genes into Fennoscandian brown hare populations

Riikka Levänen, Carl-Gustaf Thulin, Göran Spong, Jaakko L.O. Pohjoismäki & Jaakko L. O. Pohjoismäki
In Fennoscandia, mountain hare (Lepus timidus) and brown hare (Lepus europaeus) hybridize and produce fertile offspring, resulting in gene flow across the species barrier. Analyses of maternally inherited mitochondrial DNA (mtDNA) show that introgression occur frequently, but unavailability of appropriate nuclear DNA markers has made it difficult to evaluate the scale- and significance for the species. The extent of introgression has become important as the brown hare is continuously expanding its range northward, at the...

Data from: Finding flies in the mushroom soup: host specificity of fungus-associated communities revisited with a novel molecular method

Janne Koskinen, Tomas Roslin, Tommi Nyman, Nerea Abrego, Craig Michell & Eero J. Vesterinen
Fruiting bodies of fungi constitute an important resource for thousands of other taxa. The structure of these diverse assemblages has traditionally been studied with labour-intensive methods involving cultivation and morphology-based species identification, to which molecular information might offer convenient complements. To overcome challenges in DNA extraction and PCR associated with the complex chemical properties fruiting bodies, we developed a pipeline applicable for extracting amplifiable total DNA from soft fungal samples of any size. Our protocol...

Data from: Sperm pre-fertilization thermal environment shapes offspring phenotype and performance

Jukka Kekäläinen, Párástu Oskoei, Matti Janhunen, Heikki Koskinen, Raine Kortet & Hannu Huuskonen
Sperm pre-fertilization environment has recently been suggested to mediate remarkable transgenerational consequences for offspring phenotype (transgenerational plasticity, TGB), but the adaptive significance of the process has remained unclear. Here, we studied the transgenerational effects of sperm pre-fertilization thermal environment in a cold-adapted salmonid, the European whitefish (Coregonus lavaretus L.). We used a full-factorial breeding design where the eggs of five females were fertilized with the milt of 10 males that had been pre-incubated at two...

Data from: Age and quality-dependent DNA methylation correlate with melanin-based colouration in a wild bird

Carl D. Soulsbury, Anssi Lipponen, Kristie Wood, Charles A. Mein, Joe I. Hoffman, Christophe Lebigre & Joseph I. Hoffman
Secondary sexual trait expression can be influenced by fixed individual factors (such as genetic quality) but also by dynamic factors (such as age and environmentally induced gene expression) that may be associated with variation in condition or quality. In particular, melanin-based traits are known to relate to condition and there is a well-characterized genetic pathway underpinning their expression. However, the mechanisms linking variable trait expression to genetic quality remain unclear. One plausible mechanism is that...

Data from: Independent and interactive effects of immune activation and larval diet on adult immune function, growth and development in the greater wax moth (Galleria mellonella)

Organisms in the wild are likely to face multiple immune challenges as well as additional ecological stressors, yet their interactive effects on immune function are poorly understood. Insects are found to respond to cues of increased infection risk by enhancing their immune capacity. However, such adaptive plasticity in immune function may be limited by physiological and environmental constraints. Here, we investigated the effects of two environmental stressors – poor larval diet and an artificial parasite-like...
