Living on the edge: Pleistocene ice‐free refugia and collared lemming (Dicrostonyx sp.) in the North American High Arctic

Boreas, EarlyView.
Comparing the morphological variation of North American collared lemming with climatic and geographic features, as well as genetic insight and the ice sheet extend, indicate the strong geographic structure underlying the morphological diversity of the genus, that might be linked with a local Pleistocene survival in the High Arctic.

The first-order effect of Holocene Northern Peatlands on global carbon cycle dynamics [PDF]

, 2010
Given the fact that the estimated present-day carbon storage of Northern Peatlands (NP) is about 300–500 petagram (PgC, 1 petagram = 1015 gram), and the NP has been subject to a slow but persistent growth over the Holocene epoch, it is desirable to ...

Shades of empire: Evidence from Swedish and Polish–Lithuanian partitions in the Baltics

The Economic History Review, EarlyView.
Abstract In this study, we explore the long‐run effects of Swedish and Polish–Lithuanian imperial legacies in the Baltic region. Using a robust regression discontinuity design, we identify persistent differences in socio‐economic development across the South Livonia–Courland and the South Livonia–Lettgallia borders that emerged as a result of the ...

Wintering area and experience effects on spring migration strategies, timing and breeding success in Icelandic‐nesting Common Scoters (Melanitta nigra)

Ibis, EarlyView.
Earlier spring arrival of migratory birds to breeding sites and advanced breeding often bring enhanced reproductive success but demand good body‐condition. When populations exhibit extensive winter distributions, the differing energetic costs associated with the quality and migration distance to each wintering area can have implications for individual ...

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

Journal 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.
