Although studies of ancient lake fauna have provided important insights about speciation patterns and processes of organisms in heterogeneous benthic environments, evolutionary forces responsible for speciation in the relatively homogenous planktonic environment remain largely unexplored. In this study, we investigate possible mechanisms of speciation in zooplankton using the freshwater diaptomids of the ancient lakes of Sulawesi, Indonesia, as a model system. We integrate phylogenetic and population genetic analyses of mitochondrial and nuclear genes with morphological and genome size data. Overall, our results support the conclusion that colonization order and local adaptation are dominant at the large, island scale, whereas at local and intralacustrine scales, speciation processes are regulated by gene flow among genetically differentiated and locally adapted populations. In the Malili lakes, the diaptomid populations are homogenous at nuclear loci, but show two highly divergent mitochondrial clades that are geographically restricted to single lakes despite the interconnectivity of the lake systems. Our study, based on coalescent simulations and population genetic analyses, indicates that unidirectional hybridization allows gene flow across the nuclear genome, but prevents the introgression of mitochondria into downstream populations. We suggest that hybridization and introgression between young lineages is a significant evolutionary force in freshwater plankton.

“…While several studies on the biogeography of the larger islands in the IAA exist (see review by Lohman et al ., ), surprisingly little is known about the timing, causes and directionality of biotic exchange on the smaller islands at the south‐eastern boundaries of Wallacea. Here, ‘Lydekker's Line’ marks a major faunal break (Figure in Rowe et al ., ), which has been crossed repeatedly by groups considered ‘good dispersers’, such as sycophagine wasps (Cruaud et al ., ), atyid crustaceans (Page et al ., ) and murine rodents (Rowe et al ., ), but appears to be almost impenetrable to ‘poor dispersers’, such as terrestrial mammals (Lydekker, ; van den Bergh et al ., ), pachychilid and rissooidean freshwater gastropods (Köhler & Dames, ; Zielske et al ., ) and freshwater fishes (Smith, ).…”

Aim Camaenidae are amongst the most diverse land snail groups in Southeast Asia and Australasia, but their phylogeny and biogeography are poorly understood. The monophyly and biogeographical origin of the Australian species has remained uncertain. Being reported from north‐western Australia as well as from the Lesser Sunda Islands, the genus Rhagada is crucial to our understanding of camaenid biogeography. By resolving the phylogeny of Rhagada, we aim to uncover spatial and temporal patterns of its diversification at the interface between Oriental and Australian biogeographical regions. Location North‐western Australia, Lesser Sunda Islands. Methods We implemented Bayesian and maximum likelihood methods to generate the most complete mitochondrial phylogeny of Rhagada land snails to date. Divergence times of clades were estimated by employing a relaxed molecular clock and two internal calibrations from fossil and tectonic data. Ancestral areas of clades were inferred using character history reconstruction based on parsimony, as implemented in Mesquite. Results Rhagada clustered into eight well‐supported clades that are restricted to certain geographical areas. Species from the Kimberley, Western Australia, formed the earliest branching clades. A single Lesser Sunda clade was sister to a radiation in the Western Australian Pilbara. Molecular age estimates placed the evolutionary origin of Rhagada between the late Miocene and early Pleistocene, and dispersal from Western Australia onto the Lesser Sunda Islands in a period between the mid‐Pliocene and early Pleistocene. Main conclusions The camaenid Rhagada originated in the Kimberley and subsequently expanded its range through the Pilbara and into the Shark Bay area, probably during the late Pliocene and mid‐Pleistocene. From the Kimberley, Rhagada snails colonized the Lesser Sunda Islands probably not before 1.9 Ma following emergence of the youngest islands, which may have acted as ‘stepping stones’. Over‐sea dispersal might have occurred during the mid‐Pleistocene when lowered sea levels facilitated faunal exchange across the region.

“…The two species included from Sulawesi resulting in an age of 10.8 (7.4–14.7) Myr for their most recent common ancestor, significantly older than the lakes from which those species were described (Hall, ; Zielske et al ., ), suggesting a more complex evolutionary pattern than assumed for other ancient lake species in that region (Stelbrink et al ., ; Von Rintelen et al ., ).…”

“…One tateid from Norfolk Island is probably extinct (Ponder, ). In the Malesian region, Tateidae have colonized the ancient lakes of Sulawesi (Haase & Bouchet, ; Zielske et al ., ) and there are a few records from New Guinea (Bernasconi, ). Taxa from South America are probably the sister group of these Australasian and Pacific island taxa (Wilke et al ., ) and, due to the lack of data, are not further considered.…”

Aim Tateid freshwater gastropods have an enigmatic distribution in the South Pacific (SP) region. We reconstructed their diversification and dispersal pathways and estimated a timeframe for their radiations. Location New Caledonia, Vanuatu, Fiji, the Austral Islands, further species from Sulawesi, Australia, New Zealand and Lord Howe Island. Methods Bayesian and maximum likelihood methods were used to calculate dated phylogenies based on two mitochondrial and three nuclear gene fragments, test hypotheses and perform ancestral range reconstructions. We compared two calibration strategies based on the COI substitution rate and two sets of island ages selected (1) independent of the ancestral range reconstruction and (2) using information from the latter. Results The common ancestor of the SP Tateidae occurred in Australia. Its descendents colonized Sulawesi and Lord Howe Island and gave rise to the radiations on New Caledonia and New Zealand. The more remote archipelagos harbouring the genus Fluviopupa Pilsbry, 1911 were colonized out of New Zealand. Fluviopupa evolved on the Austral Islands and colonized the archipelago against the progression rule from east to west. Vanuatu was colonized twice independently from the Austral Islands and served as hub for dispersal events to Fiji and Lord Howe Island. The second strategy for calibrating the time trees resulted in considerable younger colonization estimates, was generally well in accordance with the geological record and required fewer ad hoc hypotheses to explain the diversification and dispersal pattern. Main conclusions Our analyses of the evolutionary history of Tateidae across the SP revealed several enigmatic aspects not in accordance with the dominant pattern published for other taxa. In particular, the complex westward dispersal pathways of Fluviopupa, which originated on the Austral Islands but had an ancestor in New Zealand, are unique. Geographical distance was not an appropriate predictor of relationships.
