This work tested for evolutionary changes in shell albedo that might have been driven by the warming of the climate in Europe over the last half century by compiling an historical dataset for 6,515 native populations of C. nemoralis and comparing this with new data on nearly 3,000 populations.

The present study identifies Cecidophyopsis species occurring in Latvia on cultivated and wild Ribes, to assess their host range and gain insight into the genetic diversity of these insufficiently studied pests by use of multiplex PCR, rDNA sequences and morphological characters.
×Sorbaronia mitschurinii: from an artificially created species to an invasion in Europe: repeating the fate of invasive Amelanchier ×spicata, a review

- 23 December 2013
The first records of the alien lilac leafhopper, Igutettix oculatus, are reported in Latvia and Lithuania, which can be a serious plant pest during warm and dry summers and treated as an invasive species in Europe.

- BiologyZootaxa
- 5 July 2019
The present study shows that major revision is necessary for many of the eriophyoid mite species previously recorded from Latvia, as well as identifying species records that did not involve collecting and identifying actual specimens.
