Data from: ITS1 versus ITS2 as DNA metabarcodes for fungi

Rakel Blaalid, Surendra Kumar, R. Henrik Nilsson, Kessy Abarenkov, Paul M. Kirk & Håvard Kauserud
The nuclear ribosomal Internal Transcribed Spacer ITS region is widely used as a DNA metabarcoding marker to characterize the diversity and composition of fungal communities. In amplicon pyrosequencing studies of fungal diversity, one of the spacers ITS1 or ITS2 of the ITS region is normally used. In this methodological study we evaluate the usability of ITS1 vs. ITS2 as a DNA metabarcoding marker for fungi. We analyse three data sets: two comprising ITS1 and ITS2...

Data from: Latitudinal clines in alternative life histories in a geometrid moth

Panu Välimäki, Sami M. Kivelä, Maarit I. Mäenpää & Toomas Tammaru
The relative roles of genetic differentiation and developmental plasticity in generating latitudinal gradients in life histories remain insufficiently understood. In particular, this applies to determination of voltinism (annual number of generations) in short-lived ectotherms, and the associated trait values. We studied different components of variation in development of Chiasmia clathrata (Lepidoptera: Geometridae) larvae that originated from populations expressing univoltine, partially bivoltine or bivoltine phenology along a latitudinal gradient of season length. Indicative of population-level genetic...

Data from: Degree of specialization is related to body size in herbivorous insects: a phylogenetic confirmation

Robert B. Davis, Erki Õunap, Juhan Javoiš, Pille Gerhold & Toomas Tammaru
Numerous studies have suggested a general relationship between the degree of host specialization and body size in herbivorous animals. In insects, smaller species are usually shown to be more specialized than larger-bodied ones. Various hypotheses have attempted to explain this pattern but rigorous proof of the body size-diet breadth relationship has been lacking, primarily because the scarceness of reliable phylogenetic information has precluded formal comparative analyses. Explicitly using phylogenetic information for a group of herbivores...
