Enhancing Urban and Suburban Green Spaces: Dendrological Diversity and Climate Adaptation

open access: yesThe Scientific World Journal, Volume 2026, Issue 1, 2026.
This study presents the first integrated, multicity assessment of urban green infrastructure in Armenia, focusing on three major cities, Yerevan, Gyumri, and Vanadzor, that represent contrasting climatic conditions. The study combines an analysis of the present climatic conditions and green‐space structure with a long‐term assessment of dendrological ...

Fruit Traits Reflect Adaptation to Dispersers Along a Tropical Elevational Gradient

open access: yesEcology and Evolution, Volume 15, Issue 12, December 2025.
This study investigates how fruit traits related to frugivore dispersal—specifically diameter, colour and presentation—vary along an elevation gradient in Papua New Guinea. Results showed that fruit diameter decreases with elevation, bird‐attracting colours are more common at higher elevations, and branch‐borne (ramiflorous) fruits increase with ...

eDNA metabarcoding of archived leaf samples reveals arthropod diversity decline in South Korean but not in German forest ecosystems

open access: yesInsect Conservation and Diversity, Volume 18, Issue 6, Page 1150-1162, November 2025.
Environmental samples from the South Korean (A) and German (B) Environmental Specimen Banks were analysed regarding long‐term trends in canopy‐associated arthropod communities over 11 years. Samples of both Environmental Specimen Banks showed tree species‐specific arthropod communities that were significantly different from other tree species ...

Island Biogeography in the Anthropocene: Natural and Anthropogenic Drivers of Plant Diversity in the Miaodao Archipelago

open access: yesEcology and Evolution, Volume 15, Issue 10, October 2025.
This study assessed changes in vascular plant diversity across spatial gradients of area, isolation, climate, and human disturbance on 10 inhabited islands in Miaodao Archipelago. We found that island area is the most important predictor of species richness and species distribution.

Metabarcoding Reveals Fine Scale Patterns of Trophic Resource Use and Partitioning Along Gradients of Land Use and Deer Density in a Multi‐Species Ungulate Community

open access: yesEcology and Evolution, Volume 15, Issue 10, October 2025.
We used DNA metabarcoding of 2,568 fecal samples to examine seasonal diets and resource partitioning among four deer species (moose, roe deer, red deer, fallow deer) across two Swedish landscapes. Deer consumed a wide range of plants, but diets were typically dominated by a few key taxa, with distinct dietary separation between moose and smaller deer ...

The_complete_chloroplast_genome_sequence_of_Ulmus_szechuanica_(Ulmaceae)_and_its_phylogenetic_analysis-_.docx

open access: yes, 2020
Ulmus szechuanica is a species of Sect.Ulmus and Ser.Nitentes in Ulmaceae, and it is an endangered wild plant in China. The complete chloroplast genome (cp) of U. szechuanica was reported in this study. The result showed that the cp genome was 159,703 bp in length including a large single-copy (LSC) 88,039 bp and a small single-copy (SSC) 19,072 bp ...
