Abstract

Communities of insects around the world consist of unique sets of species that have evolved under different historical processes of assembly and lineage diversification. Whole-community phylogenetics can partition the shared and uniquely derived evolutionary history across sites. We used mitochondrial genome sequences of > 1000 species each from two assemblages of Coleoptera (beetles) in distantly situated tropical lowland rainforests of Malaysia and Panama for phylogenetic reconstruction and community ecological analysis. Assemblages were entirely distinct at the species level but were surprisingly similar at the family level in their overall composition and relative species richness. This pattern, coupled with a high degree of phylogenetic clustering, suggests that lineage-specific tendencies have driven evolutionarily independent yet parallel diversification across distinct regions. The inclusion of species-poor lineages reduced the level of community clustering in parallel in both sites, indicating the role of lineage-specific factors in shaping species richness and local community composition. Our findings reveal a strong connection between relative species richness in local communities and global clade sizes, and consistent phylogenetic patterns across assemblages. While biotic exchange in deep time likely played a secondary role, the primary driver appears to be the intrinsic diversification rates unique to each clade (family). Such dynamics make assembly composition more predictable, i.e. replaying the ‘evolutionary tape' would yield similar outcomes wherever a new assemblage of tropical-forest Coleoptera arises.

期刊介绍： ECOGRAPHY publishes exciting, novel, and important articles that significantly advance understanding of ecological or biodiversity patterns in space or time. Papers focusing on conservation or restoration are welcomed, provided they are anchored in ecological theory and convey a general message that goes beyond a single case study. We encourage papers that seek advancing the field through the development and testing of theory or methodology, or by proposing new tools for analysis or interpretation of ecological phenomena. Manuscripts are expected to address general principles in ecology, though they may do so using a specific model system if they adequately frame the problem relative to a generalized ecological question or problem. Purely descriptive papers are considered only if breaking new ground and/or describing patterns seldom explored. Studies focused on a single species or single location are generally discouraged unless they make a significant contribution to advancing general theory or understanding of biodiversity patterns and processes. Manuscripts merely confirming or marginally extending results of previous work are unlikely to be considered in Ecography. Papers are judged by virtue of their originality, appeal to general interest, and their contribution to new developments in studies of spatial and temporal ecological patterns. There are no biases with regard to taxon, biome, or biogeographical area.
