Genomic and Mitonuclear Patterns of Divergence Among Recently Diverged White‐Crowned Sparrow Subspecies

open access: yesEcology and Evolution, Volume 16, Issue 5, May 2026.
The study investigates genetic divergence among white‐crowned sparrow subspecies across North America, revealing three to four distinct genetic clusters based on genome‐wide SNP analysis, particularly highlighting divergence in the Z chromosome. Notably, Z. l. pugetensis consistently diverges from other populations, and a north–south split within Z. l.

Testing the Adaptive Significance of Personate Flowers in Penstemon (Plantaginaceae)

open access: yesEcology and Evolution, Volume 16, Issue 5, May 2026.
Floral diversity across plant lineages reflects evolutionary shifts in mating strategy and pollinator specificity. The genus Penstemon contains a handful of species that display personate flowers—a peculiar bee‐pollinated floral type characterized by an upward bulge in the ventral portion of the corolla tube that obstructs the floral opening.

Indirect effects of herbicide use on the Bombus community mediated through changes to shrub and forb communities

open access: yesEcosphere, Volume 17, Issue 5, May 2026.
Abstract Pesticides are used around the world to control and suppress undesirable species. In many cases the direct effects of pesticides are well understood and characterized, describing how environments are likely to be altered. However, these direct effects are likely to cause other species to respond to ecosystem alteration. For example, herbicides

Fine‐Scale Temporal Dynamics of the Honey Bee Hive Microbiome and Foraging Revealed by Airborne eDNA

open access: yesEnvironmental DNA, Volume 8, Issue 3, May–June 2026.
Airborne eDNA collected within honey bee hives reveals diverse plant and microbial communities. While richness remains stable, seasonal shifts in plant and microbiome composition highlight dynamic resource use, demonstrating eDNA's potential for non‐invasive, fine‐scale monitoring of foraging and colony health. ABSTRACT Environmental DNA (eDNA) has the

Exploring perceptions of Italian urban wildlife on TikTok

open access: yesPeople and Nature, Volume 8, Issue 5, Page 1470-1484, May 2026.
Abstract In Western cities, some animals are valued for their beauty, rarity or usefulness, while others are dismissed as unwelcome. This distinction reflects the cultural meanings attached to each species and frequently conflicts with ecological priorities.

No one‐size‐fits‐all: Trait‐dependent effects of local plant diversity on pollinators and pollination service in a densifying city

open access: yesJournal of Applied Ecology, Volume 63, Issue 5, May 2026.
Increasing local floral richness can support pollination success of specialised plants in dense urban landscapes. However, a floral enrichment strategy alone is less effective for generalist plants, which are typically more abundant in plant communities.

Special Issue: Food Sustainability, the Food System, and Alaskans [PDF]

open access: yes, 2011
[Geography] -- The Alaska Food Policy Council: Everyone knows that food is important, but our dependence upon Outside for the stuff of life has finally begun to seem, well, just a little discomfiting to Alaska's policymakers.
