	abstract = {The genus Bythinella comprises many species throughout Europe, but
species delimitation, traditionally based on shell morphology and
genital anatomy, is often a matter of debate. Out of an ongoing
large-scale project on the phylogeny of the genus, we analyzed the
relationships of species occurring in the south Austrian province
Carinthia and in neighboring Slovenia as a model for similar cases of
systematic and taxonomic ambiguity. Our analyses based on sequence data
of a fragment of COI comprising 638 bp, morphological and anatomical
investigations confirmed the presence of three species, B. opaca
(Gallenstein, 1848), B. robiciana (Clessin, 1890) and B. angelitae nom.
nov. for B. opaca ( Frauenfeld, 1857). The latter, while genetically
distinct, is morphologically and anatomically cryptic in that it can
only be distinguished from B. opaca by the denticulation of the radular
marginal teeth. B. robiciana, on the other hand, is morphologically
well defined, but genetically not separable from B. opaca, its stem
species. Thus, taxonomy in Bythinella has to be based on the
integration of morphology, anatomy and genetics. Our phylogenetic
analyses suggest that B. opaca has colonized Carinthia, which has
largely been covered by glaciers during the last ice age, along two
routes, one from the south and a second one from the southeast.},

	abstract = {1. Zebra mussels and their relatives (Dreissena spp.) have been well
studied in eastern, central and western Europe as well as in North
America, because of their invasiveness and economic importance. Much
less is known about the biology and biogeography of indigenous
(endemic) taxa of Dreissena, in the Balkans. A better knowledge of
these taxa could help us (i) understand the factors triggering
invasiveness in some taxa and (ii) identify other potentially invasive
species.
2. Using a phylogenetic approach (2108 base pairs from three gene
fragments), Dreissena spp. from natural lakes in the Balkans were
studied to test whether invasive Dreissena populations occur in such
lakes on the Balkan Peninsula, whether Dreissena stankovici really is
endemic to the ancient Lakes Ohrid and Prespa, and to infer the
phylogenetic and biogeographical relationships of Balkan dreissenids.
3. No invasive species of Dreissena, such as Dreissena polymorpha, were
recorded. The supposedly �endemic� D. stankovici is not restricted to
the ancient Lakes Ohrid and Prespa, but is the most widespread and
dominant species in the west-central Balkans. Its southern sister
taxon, Dreissena blanci, occurs sympatrically with D. stankovici in
Lakes Prespa, Mikri Prespa and Pamvotis. Both species are classified
into the subgenus Dreissena (Carinodreissena) of which the subgenus
Dreissena (Dreissena) (which includes the invasive D. polymorpha) is
the sister taxon. Dreissena blanci and D. stankovici are considered to
represent distinct species.
4. On a global scale, the two Balkan species have small ranges. An
early Pliocene time frame for the divergence of the subgenera
Carinodreissena and Dreissena is discussed, as well as potential
colonization routes of the most recent common ancestor of
Carinodreissena spp.
5. The ambiguous taxonomy of dreissenids in the Balkans is addressed.
As nominal D. blanci presbensis from Lake Prespa has nomenclatural
priority over D. stankovici, the correct name for the latter taxon
should be Dreissena presbensis.},

	abstract = {Aims Building on molecular studies of widespread Australian
vertebrates, we tested whether each of three widespread Australian bird
species, namely the singing honeyeater, Lichenostomus virescens,
spiny-cheeked honeyeater, Acanthagenys rufogularis (Passeriformes:
Meliphagidae), and black-faced woodswallow, Artamus cinereus
(Passeriformes: Artamidae), has undergone a recent (Pleistocene) range
expansion across the Australian continent. We related the findings to
the presence or absence of geographic variation in each species�
external phenotype and whether historical or non-historical factors
have been involved in generating variation.
Methods A total of 92 specimens of the three species were collected
from, as far as possible, the same localities across Australia. They
were sampled for mitochondrial DNA (mtDNA) diversity in the 1041 base
pairs of the ND2 gene, and these data were analysed with nucleotide
diversity statistics, unrooted networks, nested clade analysis, and
tests of range expansion or stability.
Results Range expansions could not be rejected in any of the species in
our study. Each had low, geographically unstructured nucleotide
diversity. Patterns of geographic variation in the singing honeyeater�s
and, to a lesser extent, the black-faced woodswallow�s external
phenotypes are not correlated with mtDNA diversity in ND2.
Main conclusions Our study adds to the increasing number of data sets
suggesting the apparent prevalence of Pleistocene population expansions
in widespread Australian birds. Furthermore, it shows that observable
geographic structure may evolve very quickly, in response either to
environmental gradients or to historical factors that operated too
recently to be detected by ND2 sequences (e.g. in the singing
honeyeater). Conversely, we have shown that a species that has had a
recent population expansion need not necessarily be geographically
invariant. To understand fully the interplay between vicariance and
dispersal in the history of widespread Australian arid-zone birds, or
between the historical and non-historical origins of their
differentiation, carefully conducted case-by-case molecular studies
will be necessary. Only then will biogeographical patterns and the
processes that led to them emerge. Study of the historical biogeography
and the more recent population history of Australian arid-zone birds
has reached a point where mtDNA-based studies, while still informative
and contributing to a growing data base of such work, should be
complemented with data from multiple, rapidly evolving nuclear loci.},

phylogeny-based hypothesis for the biogeographical relationship of
gastropods from the putative ancient Lake Egirdir, to test the
respective null hypothesis, to estimate the timing of biogeographical
events based on independent molecular clock approaches, and to
interpret the data with respect to the putative ancient character of
Lake Egirdir.
Location Lake Egirdir, western Taurus Lake District, Turkey.
Methods DNA sequences from the putatively only extant endemic taxon of
Lake Egirdir, Falsipyrgula pfeiferi, as well as representatives of
other pyrgulinid genera from Europe and western Asia are used for
phylogenetic analyses based on Bayesian inference. The respective null
hypothesis is tested utilizing parametric bootstrapping. The timing of
evolutionary events is estimated based on two independent molecular
clock approaches, which involve the modelling of judicious errors
associated with branch-length calculations and calibration points.
Results Bayesian inference indicates a very close relationship between
the Lake Egirdir and Ponto-Caspian taxa. Parametric bootstrapping},
