Mammal extinction facilitated biome shift and human population change during the last glacial termination in East-Central Europe

Scientific Reports, 2022
The study of local extinction times, together with the associated environmental and human population changes in the last glacial termination, provides insights into the causes of mega- and microfauna extinctions.

Breeding Snowy Owls Are Obligate Lemming Predators in Utqiaġvik, Alaska: Results from 30 Years of Study

Diversity
For 30 years (1992–2021), we collected pellets and pellet fragments and recorded prey cached in Snowy Owl (Bubo scandiacus) nests during the breeding season in Utqiaġvik, Alaska.

Rapid Karyotype Evolution in Lasiopodomys Involved at Least Two Autosome - Sex Chromosome Translocations. [PDF]

PLoS ONE, 2016
The generic status of Lasiopodomys and its division into subgenera Lasiopodomys (L. mandarinus, L. brandtii) and Stenocranius (L. gregalis, L. raddei) are not generally accepted because of contradictions between the morphological and molecular data.

Fire and Snow: Effects of Snowpack Variation and Wildfire on Small Mammal Dynamics in Sub‐Alpine Habitats

Ecology and Evolution, Volume 16, Issue 4, April 2026.
Global warming is increasing the risk of fire and decreasing winter snow cover in montane environments in many parts of the world. Using a long term trapping study in sub‐alpine habitats in the Australian Alps, we show that changes in the fire regime and snow conditions interact with other factors (availability of food and predation by introduced ...

Tephrocactus Lem.

, 2022
Tephrocactus Lem.: — Kiesling (1984) and Rodríguez et al. (2018) placed Tephrocactus nigrispinus (K.Schum.) Backeb. within the genus Maihueniopsis. This assumption was not supported by molecular studies (Wallace & Dickie 2002, Griffith & Porter 2009, Ritz et al. 2012).

Forbs in Viking lands: the effect of disturbing dominant graminoids on recruitment in tundra grasslands

Oikos, Volume 2026, Issue 4, April 2026.
Grasslands, by definition, are dominated by graminoids. Nevertheless, forbs also make up a substantial part of vascular plant diversity in grasslands and are important resources of mammalian herbivores. However, forb recruitment is constrained by successful dominant graminoids, limiting access to safe sites for germination.

Herbivore decline switches a high Arctic plant community from top‐down to bottom‐up control

Journal of Ecology, Volume 114, Issue 4, April 2026.
Declining abundance of large herbivores in the Arctic loosens the top‐down control on the vegetation, which now responds primarily to the changing climatic conditions and follows the general greening pattern observed in a warming Arctic. These changes may impact terrestrial ecosystem element cycling, with knock‐on effects on the dynamics in adjacent ...

Molecular sexing of brown lemming remains

Arctic Science
Accurate sex identification of prey remains can provide valuable insights into selective predation, but field studies are often constrained by degraded or digested material.

Differences in Recycled Amendment Phosphorus Solubility and Transport When Interfaced to Soils of Dissimilar Characteristics

Soil Use and Management, Volume 42, Issue 2, April‐June 2026.
ABSTRACT Increasing phosphorus (P) fertilizer use efficiency from bio‐based waste products (i.e., recycled amendments) requires promoting a larger proportion of bioavailable P in soil for plant uptake. Therefore, this study aimed to elucidate how recycled amendment P solubility and movement vary when interfaced with soils of contrasting characteristics.
