title: Data from: Different mechanisms explain decoupled co-occurrence patterns of native and non-native macroinvertebrates

description: Biological invasion is a key driver of biodiversity loss, leading to
 significant changes in community composition and structure. Hence,
 understanding how biological invasions influence community assembly
 processes is crucial for identifying invasion mechanisms and developing
 management strategies aimed at minimizing their impacts on natural
 ecosystems. Beyond environmental filtering or niche-based exclusion,
 biotic interactions (e.g., interspecific competition) between invasive and
 their native counterparts can also affect species distributions and local
 invasion dynamics. This study combined joint Species Distribution Models
 (jSDMs) with a long-term European-level dataset to uncover co-occurrence
 patterns and community organization of freshwater macroinvertebrates in
 the context of biological invasion. To do this, we considered functional
 traits, phylogenetic relationships, environmental niches, and residual
 variance potentially mirroring species-to-species interactions between
 non-native and native species. Environmental covariates exhibited
 significant differences in explaining variation of occurrences between
 native and non-native species, although environmental filtering had a more
 pronounced effect on native species. This finding supported the hypothesis
 that non-native species generally exhibit broader environmental niches.
 Indeed, our findings emphasized the importance of biotic filtering (in the
 form of interspecific competition and invasion meltdown among non-native
 species) acting beyond the abiotic environment in shaping the distribution
 of non-native and native species, providing a more nuanced view of the key
 drivers underlying invasion risk and success.

 Files and variables #### File: Data.zip **Description:** This study
 utilized four types of data: Biotrait.xlsx, which contains species trait
 data; Environment.xlsx, which includes environmental covariates;
 Polydata.xlsx, which provides taxonomic information; and Time_series.xlsx,
 which represents the macroinvertebrate dataset. In Time_series.xlsx, it
 should be noted that NA in column F indicates the absence of index
 information for the species in freshwaterecology.com, but does not affect
 the overall analysis. A detailed description of each file in the dataset
 is provided in the Readme.xlsx document. #### File: Rscript.zip
 **Description:** In this study, the "Model.R" file contains the
 components related to model construction and evaluation, and the
 "Figure.R" file includes the code used for generating the
 figures in the manuscript.  ## Code/software All data analyses and figure
 generation in this study were conducted in the R environment.
