	abstract = {Abstract\&nbsp;\&nbsp;Evolution of the mate recognition system (MRS) can play a central role in animal speciation. One dramatic consequence of changes in the MRS is the failure of individuals from divergent lineages to successfully court and mate, thereby reducing gene flow between these groups. Here, we test the role of an acoustic mating signal on mate choice in a Hawaiian cricket genus (Gryllidae: Laupala). Speciation in Laupala is proceeding at an extremely rapid rate, apparently driven by divergence in aspects of the mate recognition system, most conspicuously the pulse rate of male calling song. Previous studies demonstrate that females prefer the pulse rate of a conspecific male{\textquoteright}s song when perceived at long range, in laboratory phonotaxis trials. In this study, we examined mate choice in two species that differ dramatically in pulse rate: Laupala paranigra and Laupala kohalensis. We tested the female{\textquoteright}s preference in both species for pulse rates at close range, by providing females an opportunity to mate with hybrid males producing a range of intermediate pulse rates. Results of our study demonstrate that while strong behavioral barriers exist between these two species, variation in the pulse rate of male calling song did not predict female mate choice at close range. These results suggest a more complex architecture to mate recognition in Laupala than previously hypothesized.},

	abstract = {10.1073/pnas.242585899 It has been asserted that recent mtDNA phylogenies support the plausibility of sympatric speciation, long considered a controversial mechanism of the origin of species. If such inferences are reliable, mtDNA phylogenies should be congruent with phylogenies based on other data. In previous work, a mtDNA phylogeny suggested that diversification of the Hawaiian cricket genus was initiated by single invasions into each of several Hawaiian islands, followed by multiple sympatric divergences within each island. In contrast, a systematic hypothesis based on morphology argues that speciation in has occurred primarily in allopatry, with two independent species radiations diversifying across the archipelago. In this study, I analyze nuclear DNA (nDNA) sequences from to compare with sequences from the mtDNA. The nDNA phylogeny corroborates the hypothesis of allopatric divergence and multiple invasions, and when compared with mtDNA patterns, suggests that interspecific hybridization is a persistent feature of the history of . The discrepancy between mtDNA and nDNA phylogenies reveals that speciation histories based on mtDNA alone can be extensively misleading.},
