Impacts of climatic niche breadth, phylogeny, traits and ploidy on geographical ranges of Betula species

open access: yesJournal of Systematics and Evolution, EarlyView.
Geographical range size is a fundamental ecological characteristic of a species. We quantified the effects of phylogeny, climatic niche breadth, morphological traits and ploidy on range size variation of Betula species. Climatic niche breadth has the strongest effect on the range size variation of Betula species.

On the change of latitude of Arctic East Siberia at the end of the Pleistocene [PDF]

open access: yesarXiv, 2007
Mammoths lived in Arctic East Siberia. In this region there is not sufficient sunlight over the year for the growth of the plants on which these animals feed. Therefore the latitude of this region was lower before the end of the Pleistocene. As the cause of this geographic pole shift, we postulate a massive object, which moved in an extremely eccentric

Evidence that genetic drift not adaptation drives fast‐Z and large‐Z effects in Ficedula flycatchers

open access: yesMolecular Ecology, EarlyView.
Abstract The sex chromosomes have been hypothesized to play a key role in driving adaptation and speciation across many taxa. The reason for this is thought to be the hemizygosity of the heteromorphic part of sex chromosomes in the heterogametic sex, which exposes recessive mutations to natural and sexual selection. The exposure of recessive beneficial

The Tunguska explosion occurred in the morning of June 30, 1908, in Central Siberia, some 800 km NNW from Lake Baikal. It devastated the forested area of 2150 sq. km, flattening and scorching some 30 million trees. Before this, a luminous body flew overhead in the cloudless sky. The air waves from the explosion were recorded as far as in London.
