Comparative analysis of actinorhizal nodule and associated soil microorganism diversity and structure in three Alnus species by Aizi Tong, Wei Liu, Xiaoliang Liu, Junyi Zhu, You Zhou, Jianhua Li

“…In addition, it remains unclear about the influence of the host species and habitats on the microbial community of alder root nodules and rhizospheric soils.MethodsIn this study we sequenced the hyper-variable regions of the 16S rRNA from the root nodules and their rhizosphere soils of three alder species (Alnus mandshurica, A. sibirica, A. japonica) in northeastern China to explore the diversity, composition, network association, and nitrogen cycling pathway of the microbial communities in the actinorhizal nodules and associated soils.ResultsThe results showed that the microbial community α-diversity decreased significantly from the associated soil to the root nodule, and the microbial diversity in the root nodule of A. sibirica was not affected by the habitats. …”

Assessing the impact of deforestation of the Atlantic rainforest on ant-fruit interactions: a field experiment using synthetic fruits. by Ana Gabriela D Bieber, Paulo S D Silva, Sebastián F Sendoya, Paulo S Oliveira

“…Together with the severe loss of their primary dispersers in human-disturbed tropical forest sites, vertebrate-dispersed fruits may also be deprived of potential ant-derived benefits in these habitats due to shifts in the composition of interacting ant species. Our data illustrate the use of synthetic fruits to better understand the ecology of ant-fruit interactions in variable ecological settings, including human-disturbed landscapes.…”
