Warming summers limit reindeer grazing, weakening herbivory pressure in the mountain tundra

Ecography, Volume 2026, Issue 6, June 2026.
Climate change is predicted to alter species interactions by exposing ecosystems to increasingly frequent and intense warm spells. In the mountain tundra, grazing by large herbivores, particularly reindeer, can limit shrub expansion and preserve Arctic plant diversity.

Scientists' Warning to Humanity: Unnecessary Bureaucracy Is a Global Impediment to Productivity, Advancement of Human and Planetary Wellbeing, Science and Sustainability

Microbial Biotechnology, Volume 19, Issue 6, June 2026.
Unnecessary bureaucracy is a global impediment to progress and productivity that increases stress and lowers workplace morale and motivation. In research it smothers creativity and innovation that are key to new discoveries and the societal and environmental benefits they catalyse.

The Migration of the Lemming [PDF]

Nature, 1892
IN discussing the much-debated subject of the westward migration of the Norwegian lemming, the primary cause—as it appears to me—has been altogether overlooked.

Can Transfer Learning Overcome the Challenge of Identifying Lemming Species in Images Taken in the near Infrared Spectrum?

Proceedings
Using a camera system developed earlier for monitoring the behavior of lemmings under the snow, we are now able to record a large number of short image sequences from this rodent which plays a central role in the Arctic food web.

Contradictory instruments undermine the implementation of agricultural nutrient management policy mixes

Agronomy Journal, Volume 118, Issue 3, May/June 2026.
Abstract Optimizing agricultural nitrogen (N) and phosphorus (P) nutrient application and crop structure regulation are common ways to control non‐point pollution. However, comprehensive effects of nutrient surplus and farmers’ revenue remain poorly understood.

First record of a least weasel in Nunavik

Arctic Science, 2023
The spatial distributions of several small mammals in Nunavik, Québec, Canada, currently do not rely on any recorded observations due to the rarity of wildlife surveys in that area. This is concerning because understanding changes in wildlife populations

Does water vole diet meet the prerequisites of the “plant hypothesis” for explaining population cycles?

Ecosphere, Volume 17, Issue 5, May 2026.
Abstract Rodent population cycles are observed in highly seasonal environments. As most rodents are herbivorous, the availability and the quality of their food resources vary greatly across seasons. Furthermore, it is well documented that herbivore densities have a measurable effect on vegetation and, conversely, that vegetation dynamics can influence ...

Of Titans and Terraria: Exploring and Conceptualising Philanthropic Foundations Through the Lens of Metaphors

Journal of Philanthropy, Volume 31, Issue 2, May 2026.
ABSTRACT Addressing ongoing calls for a more robust understanding of philanthropic foundations, this paper uses metaphor analysis to map and analyse analogical metaphors on foundations—metaphors that make a direct comparison between philanthropic foundations and another domain—put forward in academic and non‐academic discourse.

Active power loss diminution by Greenland wolf optimization algorithm

Journal of Applied Research on Industrial Engineering, 2020
In this work, Greenland Wolf Optimization (GW) algorithm has been applied for real power loss reduction. Natural actions of the Greenland wolf have been mimicked to design the GW algorithm.
