In this talk, we travel back to the cradle of plant geography both in the literal and figurative sense. I present the results of a 2012 resurvey of Chimborazo, finding strong upward shifts in the vegetation, and discuss some of the challenges and potentials of using historical datasets for documenting biotic responses to global environmental change. We also explore Humboldt’s pioneering insights on the broad-scale patterns of nature and relevance to biogeography. I highlight a few ways in which our understanding of the world has remained much the same as Humboldt’s, and views that have changed drastically thanks to new theories, data, and methods. Finally, I argue that his holistic approach and view that “everything is interconnected” remains ever so important both to the field and for addressing global challenges of the Anthropocene. P2 Hybridization fuels adaptive radiation of cichlid fishes Joana Meier, University of Cambridge; Ole Seehausen, University of Bern and EAWAG, Switzerland Lake Victoria in East Africa was colonized by five different lineages of cichlid fishes. One of them diversified into 500 species, whereas the others did not even speciate once. This is highly replicated among all major lakes in the Lake Victoria Region, whereby always the same lineage diversified in each lake forming so-called adaptive radiations. With genomic and phylogenetic methods, we found that this one lineage is able to diversify rapidly because it is of hybrid origin between two divergent cichlid lineages from different drainage systems. The large genetic variation resulting from the combined gene pools of the two ancestral lineages, facilitated rapid diversification. Even though Lake Victoria is only 15,000 years old, this lineage diversified into 500 species ranging from algae scrapers, molluscivores, and zooplanktivores to large predators. We show that these species really evolved in only 15,000 years in the lake through selection on pre-existing variation that was generated through the hybridization event at the origin of the species group. Similarly, in the African Lake Mweru, we discovered multiple adaptive radiations of cichlid fishes. We found that all of them evolved from hybrid ancestry between two or more ancestral lineages from different drainage systems that came into contact during a river capture event about 1 million years ago. Also in this system the large genetic variation generated during the hybridization event facilitated rapid diversification. We propose that hybridization may be key to rapid diversification in general.

In particular, mountains in the Neotropics exhibit remarkable beta diversity reflecting species turnover along elevational gradients. Elevational replacements of species have been known since early surveys of the tropics as evidenced by work by Alexander von Humboldt on the geography of plants, but data on how such replacements arise are scarce, limiting our understanding of mechanisms underlying patterns of diversity. I will present data from recent studies in which collaborators and I evaluated hypotheses posed to account for the origin of elevational replacements in Neotropical birds including the Henicorhina leucophrys complex (Troglodytidae) and the genus Scytalopus (Rhinocryptidae), two groups with limited dispersal abilities but broad geographic ranges in tropical mountains. Using phylogeographic data for H. leucophrys and a robust molecular phylogeny for Scytalopus, we found that most cases of elevational replacements involve populations or species not closely related to each other. These results, as well as our research on other clades, suggest that replacements of species along elevational gradients result primarily from secondary contact following allopatric speciation and not via parapatric speciation along mountain slopes. Our study suggests that accumulation of species diversity in montane environments reflects colonization processes as opposed to in situ divergence even in dispersal- limited animals.
