Data from: Genetic relationships and ecological divergence in Salix species and populations in Taiwan

Chun-Lin Huang, Chung-Te Chang, Bing-Hong Huang, Jeng-Der Chung, Jui-Hung Chen, Yu-Chung Chiang & Shih-Ying Hwang
Linking ecology with evolutionary biology is important to understand how environments drive population and species divergence. Phenotypically diverse Salix species, such as lowland riparian willow trees and middle- to high-elevation multistemmed shrubs and alpine dwarf shrubs, provide opportunities for studying genetic divergence driven by ecological factors. We used amplified fragment length polymorphism (AFLP) to quantify the genetic variation of 185 individuals from nine populations of four Salix species in Taiwan. Our phylogenetic analyses distinguished two...

Data from: Community structure influences species’ abundance along environmental gradients

Antti P. Eloranta, Ingeborg P. Helland, Odd Terje Sandlund, Trygve Hesthagen, Ola Ugedal & Anders G. Finstad
Species response to abiotic environmental variation can be influenced by local community structure and interspecific interactions, particularly in restricted habitats such as islands and lakes. In temperate lakes, future increase in water temperature and runoff of terrestrial (allochthonous) dissolved organic carbon (DOC) are predicted to alter community composition and the overall ecosystem productivity. However, little is known about how the present community structure and abiotic environmental variation interact to affect the abundance of native fish...

Data from: Highly overlapping winter diet in two sympatric lemming species revealed by DNA metabarcoding

Eeva M. Soininen, Gilles Gauthier, Frédéric Bilodeau, Dominique Berteaux, Ludovic Gielly, Pierre Taberlet, Galina Gussarova, Eva Bellemain, Kristian Hassel, Hans K. Stenøien, Laura Epp, Audun Schrøder-Nilsen, Christian Brochmann, Nigel G. Yoccoz & Audun Schrøder-Nielsen
Sympatric species are expected to minimize competition by partitioning resources, especially when these are limited. Herbivores inhabiting the High Arctic in winter are a prime example of a situation where food availability is anticipated to be low, and thus reduced diet overlap is expected. We present here the first assessment of diet overlap of high arctic lemmings during winter based on DNA metabarcoding of feces. In contrast to previous analyses based on microhistology, we found...

Data from: Reconstructing the invasion history of Heracleum persicum (Apiaceae) into Europe

Dilli P. Rijal, Torbjørn Alm, Šárka Jahodova, Hans K. Stenøein & Inger G. Alsos
Sparse, incomplete and inappropriate historical records of invasive species often hamper invasive species management interventions. Population genetic analyses of invaders might provide a suitable context for the identification of their source populations and possible introduction routes. Here, we describe the population genetics of Heracleum persicum Desf. ex Fisch and trace its route of introduction into Europe. Microsatellite markers revealed a significantly higher genetic diversity of H. persicum in its native range, and the loss of...

Data from: The genetic relatedness in groups of joint-nesting Taiwan Yuhinas: low genetic relatedness with preferences for male kin

Mark Liu, Quen-Dian Zhong, Yi-Ru Cheng, Shou-Hsien Li, Shu Fang, Chang-En Pu, Hsiao-Wei Yuan & Sheng-Feng Shen
The relative importance of direct and indirect fitness and, thus, the role of kinship in the evolution of social behavior is much debated. Studying the genetic relatedness of interacting individuals is crucial to improving our understanding of these issues. Here, we used a seven-year data set to study the genetic structure of the Taiwan yuhina (Yuhina brunneciceps), a joint-nesting passerine. Ten microsatellite loci were used to investigate the pair-wised relatedness among yuhina breeding group members....

Data from: Trace DNA from insect skins: a comparison of five extraction protocols and direct PCR on chironomid pupal exuviae

Petra Kranzfelder, Torbjørn Ekrem & Elisabeth Stur
Insect skins (exuviae) are of extracellular origin and shed during moulting. The skins do not contain cells or DNA themselves, but epithelial cells and other cell-based structures might accidentally attach as they are shed. This source of trace DNA can be sufficient for PCR amplification and sequencing of target genes and aid in species identification through DNA barcoding or association of unknown life stages. Species identification is essential for biomonitoring programs, as species vary in...
