Abstract
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.

Different mechanisms explain decoupled co-occurrence patterns of native and non-native macroinvertebrates
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.
