Light Paths and Dark Valleys: Topographic Complexity and Mammal Occupancy in a Semi‐Arid Mountain Landscape

open access: yesEcology and Evolution, Volume 16, Issue 2, February 2026.
Topographically complex mountainous regions are critical for biodiversity conservation, supporting high beta diversity, endemic species, and essential ecosystem services. Despite their importance, the fine‐scale effects of topographic metrics such as slope, ruggedness, and solar gain on mammal habitat use remain poorly understood.

Acidification of Biogas Residues Stimulates Manganese Uptake in Wheat

open access: yesJournal of Plant Nutrition and Soil Science, Volume 189, Issue 1, Page 49-58, February 2026.
ABSTRACT Background Efficient application of organic fertilizers contributes to resource‐efficient agriculture. Acidification of liquid manure effectively reduces ammonia (NH3) emissions. However, the effect of acidification on other plant nutrients, such as Mn, often a yield‐limiting nutrient in cereal production, is not well understood.

A graduated nativeness definition for overcoming dilemmas and difficulties of vascular plant species

open access: yesOikos, Volume 2026, Issue 2, February 2026.
Nativeness is a concept central to biodiversity conservation and invasion biology, but there are several problems related to a classic binary nativeness definition. Dilemmas arise from the dynamic nature of species' distribution ranges on longer time scales, and difficulties arise in the application to smaller regions defined by arbitrary borders, and ...
