Abstract Aim We studied the niche evolution and diversification modes in transisthmian Alpheus shrimps by examining interplay between environmental divergence conservatism allopatric sister species. In a broader perspective, current study analysed of climatic role environment species shrimp. Location Atlantic Eastern‐Pacific oceans. Taxon (Caridea: Alpheidae). Methods assembled georeferenced occurrences for 33 (with 24 species) from time‐calibrated molecular phylogeny. modelled their ecological niches assessed overlap through pairwise comparisons. Additionally, we performed phylogenetic reconstructions ancestral niche, each axis. Results Our results demonstrate that thermal tolerances, food availability hydrodynamic forces were relevant axes evolutionary processes . Among 528 paired comparisons, found most divergent, including 12 clades formed pairs (in only two these fully equivalent). Phylogenetic showed an initial all axes, with divergences intensifying last million years. Main Conclusions evidence confirms relevance changes occurred West East Pacific species, as well emergence some lineages. findings provide different speciation period consistent closure Isthmus Panama.
