“…cinereus were possible based on prevailing physical conditions and energetics of migrating individuals. They are also consistent with other phylogeographic studies showing that species groups of some terrestrial Hawaiian taxa were founded by multiple historic colonizations, including ducks ( Anas sp., [41]), succineid snails [42], and katydids [43], suggesting that multiple taxa have been able to repeatedly overcome the significant challenges associated with the colonization of these remote islands.…”

Two Tickets to Paradise: Multiple Dispersal Events in the Founding of Hoary Bat Populations in Hawai'i

The Hawaiian islands are an extremely isolated oceanic archipelago, and their fauna has long served as models of dispersal in island biogeography. While molecular data have recently been applied to investigate the timing and origin of dispersal events for several animal groups including birds, insects, and snails, these questions have been largely unaddressed in Hawai'i’s only native terrestrial mammal, the Hawaiian hoary bat, Lasiurus cinereus semotus. Here, we use molecular data to test the hypotheses that (1) Hawaiian L. c. semotus originated via dispersal from North American populations of L. c. cinereus rather than from South American L. c. villosissimus, and (2) modern Hawaiian populations were founded from a single dispersal event. Contrary to the latter hypothesis, our mitochondrial data support a biogeographic history of multiple, relatively recent dispersals of hoary bats from North America to the Hawaiian islands. Coalescent demographic analyses of multilocus data suggest that modern populations of Hawaiian hoary bats were founded no more than 10 kya. Our finding of multiple evolutionarily significant units in Hawai'i highlights information that should be useful for re-evaluation of the conservation status of hoary bats in Hawai'i.

“…Most important support for the distinctiveness of the Balkan species comes from molecular data as all of the phylogenetic analyses confirmed the species are monophyletic. In addition, pairwise genetic divergence between species is high, about or above the mean for closely related allo-/parapatric orthopterans (e.g., Allegrucci et al, 2005;Shapiro et al, 2006) and even about the mean between-families distances recorded for some insect orders (Hebert et al, 2003). our data indicated that the significant genetic distances between selected taxa were largest between P. macedonicus and P. illyricus.…”

abstract. A review of the Balkan representatives of the genus Psorodonotus was made with the aim of revealing the relationships between taxa and their systematic arrangement. For this purpose we used morphological (qualitative and quantitavive), acoustic (amplitude-temporal song parameters) and molecular (mtDnA CoI gene sequence) data. The analyses and comparisons with other taxa of Psorodonotus support the distinction of three species occurring on the Balkan Peninsula: P. fieberi, P. illyricus and P. macedonicus. Analysis of the CoI sequences suggested the following relationships: outgroups + (P. illyricus + (P. fieberi + (P. macedonicus + P. caucasicus))). All available information on the distribution of the Balkan taxa was synthesized and mapped.

Here we introduce a novel quantitative technique for visualizing hierarchically organized data in a geographic context. In contrast to existing techniques, our visualization emphasizes the hierarchical relationships in the data by depicting them in a standard tree format that takes advantage of many fundamental perceptual properties. Our technique allows users to define a geographic axis and visualize how well a tree correlates with the ordering of geographical locations along this axis. This is accomplished by finding the ordering of leaf nodes, subject to the constraints of the tree topology, which minimizes the number of crossings that occur between lines that connect leaf nodes to their associated geographic locations. In this optimal layout, any crossings that occur between these lines indicate discordance between the topology of the tree and the user defined geographic axis. We have developed a branch-and-bound algorithm that allows optimal leaf orderings to be determined quickly enough to support interactive exploration of different geographic axes even for large multifurcating hierarchies. The quantitative nature of our visualization has allowed us to specify a permutation test for determining if the relationship between a tree topology and a geographic axis is statistically significant. In this paper, the utility of our visualization is demonstrated on biological data sets, but our method is applicable to any hierarchical data where geographic structure may be of interest.
