Heat drastically alters floral color and pigment composition without affecting flower conspicuousness

open access: yesAmerican Journal of Botany, Volume 113, Issue 1, January 2026.
Abstract Premise Floral pigments primarily serve to attract pollinators through color display and also contribute to protection against environmental stress. Although pigment composition can be plastically altered under stress, its impact on pollinator color perception remains poorly understood.

Tree defenses, host choice, and reproductive success of a native bark beetle under novel outbreak conditions

open access: yesEcological Applications, Volume 36, Issue 1, January 2026.
Abstract Bark beetles of the genus Dendroctonus are some of the most important disturbance agents in North American forests, having colonized conifers for millions of years. The selection pressure posed by tree‐killing bark beetles pushed trees to develop an arsenal of defensive strategies to which beetles have adapted in their turn.

Modeling Climate Change Impacts on a Socioeconomically Vital Plant: The Case of Comanthera elegans (Goldenfoot Flower)

open access: yesEcology and Evolution, Volume 16, Issue 1, January 2026.
Comanthera elegans, an ecologically important species in rocky grasslands, is projected to face significant habitat loss under future climate change scenarios. Modeling with the Maxent algorithm showed that its suitable habitats, defined by high rainfall seasonality and moderate temperatures, are at risk, especially under high greenhouse gas emissions.

Deterministic and Stochastic Processes Regulate Co‐Occurrence Network Structure and Shape Macroinvertebrate Diversity in Karst Environment

open access: yesEcology and Evolution, Volume 16, Issue 1, January 2026.
Keystone taxa and co‐occurrence network modules are fundamental basis for maintaining biodiversity in macroinvertebrate communities. Modules enhance interactions among macroinvertebrates and promote species coexistence which further influences diversity.

Bee on Boron—Sufficient Boron Supply of Brassica napus Is Crucial for Attracting Pollinating Insects to Ensure Seed Yield

open access: yesEcology and Evolution, Volume 16, Issue 1, January 2026.
The study demonstrates that sufficient B supply is crucial for successful rapeseed flower growth and fertility as well as for attracting pollinating insects, thus securing yield in a pollinator‐dependent crop. It is illustrated that climate change can pose a threat to crop yield via both direct effects, that is, an impaired nutrient uptake, and ...
