What is Dispersal-Vicariance in Dung Beetle Distributions?

Dispersal-vicariance analysis in dung beetle distributions models historical Scarabaeinae range evolution across the Americas using DIVA and ancestral range estimation to link geological events with current endemism patterns.

This subtopic examines Scarabaeinae (dung beetles) biogeography through dispersal-vicariance paradigms, focusing on vicariance driven by continental drift and mountain uplift. Methods like DIVA reveal Gondwanan origins and K-Pg survival (Gunter et al., 2016, 110 citations). Over 300 citations in key papers span Mexico to Caribbean components (Morrone, 2005, 312 citations).

Key Challenges

Why It Matters

Dispersal-vicariance models explain Scarabaeinae diversification, informing conservation amid habitat fragmentation in the Americas (Morrone, 2005). They link geological history to beta diversity, aiding predictions of endemism under climate change (Gunter et al., 2016). Crews and Esposito (2020, 63 citations) apply this to Caribbean arthropods, enhancing invasive species management.

Key Research Challenges

Incomplete Scarabaeinae Phylogeny

Sparse molecular data hinders accurate DIVA reconstructions for dung beetles (Gunter et al., 2016). Undescribed species bias ancestral range estimates (Eberle et al., 2016, 46 citations). Over 50% of Neotropical Scarabaeinae lack sequences.

Distinguishing Dispersal vs Vicariance

Methods like PAE describe patterns but fail explanatory power (Garzón-Orduña et al., 2008, 36 citations). Hovenkamp's vicariance tests yield conflicting results across datasets (Fattorini, 2008, 13 citations). Geological calibration remains imprecise for Miocene events.

K-Pg Extinction Integration

Dung beetle survival post-K-Pg challenges co-extinction hypotheses with dinosaurs (Gunter et al., 2016). Reconciling fossil gaps with molecular clocks requires multi-locus data. Caribbean datasets show mixed signals (Crews and Esposito, 2020).
