Landscape influence on pollinator population genetic connectivity

Insect Conservation and Diversity, Journal Year: 2025, Volume and Issue: unknown

Published: Jan. 17, 2025

Abstract Insect pollinators face numerous threats, including habitat loss and population fragmentation. The effects of human‐altered landscapes on connectivity need to be better understood inform effective mitigation measures. We examined the literature landscape heterogeneity genetic in two key pollinator groups: bees (Hymenoptera: Anthophila) hoverflies (Diptera: Syrphidae). identified 113 studies from 59 countries, covering 96 bee 21 hoverfly species. However, biased taxonomic geographical coverage limited broad conclusions regarding species susceptibility isolation. Notably, remain significantly understudied, hampering comprehensive assessments patterns. While some demonstrated differentiation across tens kilometres, others maintained entire continents. Various features, water bodies mountain ranges, often acted as barriers gene flow, while impacts deforestation, agriculture, urbanisation were mixed. Biological traits like body size, resource specialisation, sizes found influence contrasting results precluded conclusive findings. Future research should include evaluations time lags statistical power determine appropriateness selected tools for testing hypotheses recent pollinators. Owing increased interest corridors, encompassing a wider range species, habitats, improved study designs, is needed provide an evidence‐based framework conservation

Flowering Plant Microbiomes and Network Interactions Across an Urban Gradient

Environmental Microbiology, Journal Year: 2025, Volume and Issue: 27(4)

Published: March 28, 2025

ABSTRACT We used flowers to explore how ephemeral anthosphere microbiomes differ among flowering plant species and along an urban gradient. Here, we sequenced 16S rRNA for bacteria, ITS1 fungi rbcL DNA from 10 different sampled characterise gradient identify important network interactions. Bacterial fungal flower significantly differed in diversity across species, especially Asteraceae Fabaceae. Across all analyses, four taxa, the bacteria Pantoea Rosenbergiella Alternaria Cladosporium were highly prevalent contributed majority of microbiome composition differences observed between species. These taxa harbour strains or that may be either pathogenic beneficial plants. a land use gradient, community bacterial was stable consistent. Flower‐plant networks confirmed focal families abundance on each flower, with addition Paulowniaceae, suggesting pollinators visiting also visit this family. Our findings reveal are diverse at level encouragingly remain robust against urbanisation.

The potential spatiotemporal distribution patterns of Avena nuda and Avena sativa from global perspective provide new insights for the cultivation of commonly cultivated oats

BMC Plant Biology, Journal Year: 2025, Volume and Issue: 25(1)

Published: April 28, 2025

Commonly cultivated oats (Avena nuda and Avena sativa) play an important role in agricultural planting structure adjustment, ecological environment protection grassland animal husbandry development, their effective cultivation is conducive to food security degradation restoration. This study comprehensively collected the geographic distribution environmental data of A. sativa from global regions, ensembled niche Marxan model were used predict potential spatiotemporal pattern commonly oats, further explore factors that affected spatial genetic diversity pattern. The results showed that: (1) suitability regions concentrated plateau (spanning 25°~45°N, 90°~125°E; 40°~60°N, 10°W ~ 35°E) plain 35°~65°N, 55°E; 30°~50°N, 65°W 100°E), respectively.

Published: Oct. 1, 2024

Abstract The implementation of omics technologies and associated bioinformatics approaches hold significant promise for generating additional evidence food feed risk assessments thereby enhancing the European Food Safety Authority (EFSA) capacity to deliver scientific opinions guidance documents in future. To explore this possibility, EFSA launched a Call development roadmap identify main actions needed wider use Omics future assessments. address objective, action outlines six project proposals. These proposals are based on comprehensive mapping state‐of‐the‐art research, EFSA's activities as well current planned from other relevant regulatory bodies organisations. outlined recommendations also some identified knowledge gaps highlight added value that further investments different & safety domains could bring. In addition, work addresses key challenges blockers might hinder integration assessment leverages opportunities cooperation with external stakeholders. Finally, provides suggestions how may more broadly effectively engage stakeholders science.
