Abstract: Aim We investigated the hypothesis that flood decreases taxonomic and functional beta diversity of Chironomidae (Diptera) larvae among floodplain lakes, causing biotic homogenization. Methods collected benthic samples using a modified Petersen grab in 18 lakes period (March 2011) drought (September Upper Paraná River floodplain. compared periods multivariate dispersion analysis (PERMDISP). Results found similar between hydrological periods. Conclusions did not find evidence homogenization due to pulse. Our findings suggest other mechanisms besides increasing connectivity environmental similarity pulse may structure community, such as variation identity flood-tolerant morphospecies across lakes.

Abstract Biodiversity loss caused by biological invasions is an ecological problem on a global scale, and understanding the mechanism of invasion basis for managing non‐native species. The biotic resistance hypothesis proposes that species‐rich native communities are less susceptible to because limited resources available species, therefore comparing resource utilization patterns different can reveal mechanisms specific species at community level. We selected Lake Taihu, where icefish ( Neosalanx taihuensis Chen) originated, Fuxian, invaded, as research objects. calculated fish functional diversity indexes, including richness (FRic), evenness (FEve), divergence (FDiv), reflect differences in niche based four quarterly survey data from two lakes. random forests model explored relationship between indexes environmental variables. Our results showed more diverse (high FRic), space (low FEve), competitive pressure FDiv) Fuxian were identified critical important factors maintaining current equilibrium state after successful icefish. bottom‐up effects mainly affected Fuxian. They differed those Taihu primarily influenced top‐down effects. Enhancing limiting zooplankton controlling This study offers new perspective studying mechanism, provides scientific guidance
