Microbial composition and diversity across invasive and native spiders in the pacific islands

This dataset comprises microbiome sequencing data collected from
co-occurring native and invasive spider species sampled across three
distinct locations in the Hawaiian Islands, alongside mainland reference
populations. The data include gut microbial community profiles cleaned
using QIIME2 and taxonomically assigned to Amplicon Sequence Variants
(ASVs) using the SILVA database for annotating bacterial taxonomic groups
to sequence information. The final dataset consists of an ASV table,
taxonomic table, metadata file, and phylogenetic tree files that were then
subjected to downstream processing using phyloseq, where vertically
transmitted endosymbionts and environmentally acquired microbes were
separately analyzed to observe differences across invasion status. This
dataset was used to observe variation in microbial abundance and diversity
across invasive and native taxa, supporting further investigations into
the role of microbiota in arthropod adaptation to novel environments.
Thus, this dataset has potential for reuse in studies of invasion biology,
microbial ecology, and host-microbe interactions. Ethical considerations
and site-specific sampling metadata are included to facilitate
reproducibility and appropriate data reuse.
