text: The Brazilian Merganser is a very rare and threatened species that nowadays
inhabits only a few protected areas and their surroundings in the Brazilian territory.
In order to estimate the remaining genetic diversity and population structure
in this species, two mitochondrial genes were sequenced in 39 individuals belonging
to two populations and in one individual collected in Argentina in 1950. We found
a highly significant divergence between two major remaining populations of Mergus
octosetaceus, which suggests a historical population structure in this species.
Furthermore, two deeply divergent lineages were found in a single location, which
could due to current or historical secondary contact. Based on the available genetic
data, we point out future directions which would contribute to design strategies
for conservation and management of this threatened species.

text: "Viral manipulation of transduction pathways associated with key cellular
functions such as survival, response to microbial infection, and cytoskeleton
reorganization can provide the supportive milieu for a productive infection. Here,
we demonstrate that vaccinia virus (VACV) infection leads to activation of the
stress-activated protein kinase (SAPK)/extracellular signal-regulated kinase (ERK)
4/7 (MKK4/7)-c-Jun N-terminal protein kinase 1/2 (JNK1/2) pathway; further, the
stimulation of this pathway requires postpenetration, prereplicative events in
the viral replication cycle. Although the formation of intracellular mature virus
(IMV) was not affected in MKK4/7- or JNK1/2-knockout (KO) cells, we did note an
accentuated deregulation of microtubule and actin network organization in infected
JNK1/2-KO cells. This was followed by deregulated viral trafficking to the periphery
and enhanced enveloped particle release. Furthermore, VACV infection induced alterations
in the cell contractility and morphology, and cell migration was reduced in the
JNK-KO cells. In addition, phosphorylation of proteins implicated with early cell
contractility and cell migration, such as microtubule-associated protein 1B and
paxillin, respectively, was not detected in the VACV-infected KO cells. In sum,
our findings uncover a regulatory role played by the MKK4/7-JNK1/2 pathway in
cytoskeleton reorganization during VACV infection.\r\n"

text: The kingdom of fungi provides model organisms for biotechnology, cell biology,
genetics, and life sciences in general. Only when their phylogenetic relationships
are stably resolved, can individual results from fungal research be integrated
into a holistic picture of biology. However, and despite recent progress, many
deep relationships within the fungi remain unclear. Here, we present the first
phylogenomic study of an entire eukaryotic kingdom that uses a consistency criterion
to strengthen phylogenetic conclusions. We reason that branches (splits) recovered
with independent data and different tree reconstruction methods are likely to
reflect true evolutionary relationships. Two complementary phylogenomic data sets
based on 99 fungal genomes and 109 fungal expressed sequence tag (EST) sets analyzed
with four different tree reconstruction methods shed light from different angles
on the fungal tree of life. Eleven additional data sets address specifically the
phylogenetic position of Blastocladiomycota, Ustilaginomycotina, and Dothideomycetes,
respectively. The combined evidence from the resulting trees supports the deep-level
stability of the fungal groups toward a comprehensive natural system of the fungi.
In addition, our analysis reveals methodologically interesting aspects. Enrichment
for EST encoded data-a common practice in phylogenomic analyses-introduces a strong
bias toward slowly evolving and functionally correlated genes. Consequently, the
generalization of phylogenomic data sets as collections of randomly selected genes
cannot be taken for granted. A thorough characterization of the data to assess
possible influences on the tree reconstruction should therefore become a standard
in phylogenomic analyses.

text: Supertree methods are widely applied and give rise to new conclusions about
phylogenies (e.g., Bininda-Emonds et al. 2007). Although several desiderata for
supertree methods exist (Wilkinson, Thorley, et al. 2004), only few of them have
been studied in greater detail, examples include shape bias (Wilkinson et al.
2005) or pareto properties (Wilkinson et al. 2007). Here I look more closely at
two matrix representation methods, matrix representation with compatibility (MRC)
and matrix representation with parsimony (MRP). Different null models of random
data are studied and the resulting tree shapes are investigated. Thereby I consider
unrooted trees and a bias in tree shape is determined by a tree balance measure.
The measure for unrooted trees is a modification of a tree balance measure for
rooted trees. I observe that depending on the underlying null model of random
data, the methods may resolve conflict in favor of more balanced tree shapes.
The analyses refer only to trees with the same taxon set, also known as the consensus
setting (e.g., Wilkinson et al. 2007), but I will be able to draw conclusions
on how to deal with missing data.

text: 'Background: Supertree methods combine overlapping input trees into a larger
supertree. Here, I consider split-based supertree methods that first extract the
split information of the input trees and subsequently combine this split information
into a phylogeny. Well known split-based supertree methods are matrix representation
with parsimony and matrix representation with compatibility. Combining input trees
on the same taxon set, as in the consensus setting, is a well-studied task and
it is thus desirable to generalize consensus methods to supertree methods. Results:
Here, three variants of majority-rule (MR) supertrees that generalize majority-rule
consensus trees are investigated. I provide simple formulas for computing the
respective score for bifurcating input- and supertrees. These score computations,
together with a heuristic tree search minmizing the scores, were implemented in
the python program PluMiST (Plus- and Minus SuperTrees) available from http://www.cibiv.at/software/
plumist. The different MR methods were tested by simulation and on real data sets.
The search heuristic was successful in combining compatible input trees. When
combining incompatible input trees, especially one variant, MR(-) supertrees,
performed well. Conclusions: The presented framework allows for an efficient score
computation of three majority-rule supertree variants and input trees. I combined
the score computation with a heuristic search over the supertree space. The implementation
was tested by simulation and on real data sets and showed promising results. Especially
the MR(-) variant seems to be a reasonable score for supertree reconstruction.
Generalizing these computations to multifurcating trees is an open problem, which
may be tackled using this framework.'

text: "Background: The availability of many gene alignments with overlapping taxon
sets raises the question of which strategy is the best to infer species phylogenies
from multiple gene information. Methods and programs abound that use the gene
alignment in different ways to reconstruct the species tree. In particular, different
methods combine the original data at different points along the way from the underlying
sequences to the final tree. Accordingly, they are classified into superalignment,
supertree and medium-level approaches. Here, we present a simulation study to
compare different methods from each of these three approaches.\r\n\r\nResults:
We observe that superalignment methods usually outperform the other approaches
over a wide range of parameters including sparse data and gene-specific evolutionary
parameters. In the presence of high incongruency among gene trees, however, other
combination methods show better performance than the superalignment approach.
Surprisingly, some supertree and medium-level methods exhibit, on average, worse
results than a single gene phylogeny with complete taxon information.\r\n\r\nConclusions:
For some methods, using the reconstructed gene tree as an estimation of the species
tree is superior to the combination of incomplete information. Superalignment
usually performs best since it is less susceptible to stochastic error. Supertree
methods can outperform superalignment in the presence of gene-tree conflict."
