Antagonistic Rewiring and Turnover Patterns in a Neotropical Fish–Parasite Metanetwork
Freshwater Biology, Volume 70, Issue 7, July 2025.ABSTRACT Integrating beta‐diversity and network analyses is an emerging approach for understanding the spatial structure of species communities. For instance, although the presence of hosts affects parasite species distribution, environmental factors can either restrict or promote the occurrence of certain parasite species by changing the abundance of ...
