Deciphering Metazoan Phylogeny: The Need for Additional Molecular Data 1
"... SYNOPSIS. Our interpretation of the evolution of development, morphology, and diversity of multicellular animals hinges on a clear understanding of the phylogenetic relationships of metazoans. Currently, the field of metazoan phylogeny is in a state of flux, with new hypotheses of metazoan relations ..."

Animal phylogeny and the ancestry of bilaterians: inferences from morphology and 18S rDNA gene sequences
- Evol. Dev
, 2001
"... SUMMARY Insight into the origin and early evolution of the animal phyla requires an understanding of how animal groups are related to one another. Thus, we set out to explore animal phylogeny by analyzing with maximum parsimony 138 morphological characters from 40 metazoan groups, and 304 18S rDNA s ..."

Interpreting the earliest metazoan fossils: what can we learn
- American Zoologist
, 1998
"... SYNOPSIS. The Ediacaran fossils of the latest Precambrian have at one time or another been grouped with almost every extant kingdom, and also lumped into separate kingdom-level taxa. This has often been based on the facile use of a few characters, or on some sort of "overall similarity. " ..."

Grazing by mesozooplankton and metazoan microplankton on nanophytoplankton in a mesocosm experiment in the northern Baltic
"... Abstract Grazing by two size classes of metazooplankton, mesozooplankton(Meso;>140 um in size) and metazoan microplankton (Micro; 100-140 urn in size), was studied in a mesocosm experiment carried out off the SW coast of Finland, northern Baltic Sea, in late summer. During the 3 week study, the m ..."

A Comparative Analysis of Transcription Factor Expression during Metazoan Embryonic Development
, 2013
"... During embryonic development, a complex organism is formed from a single starting cell. These processes of growth and differentiation are driven by large transcriptional changes, which are following the expression and activity of transcription factors (TFs). This study sought to compare TF expressio ..."

METAZOAN PARASITES OF FISH FROM THE ŁEBSKO LAGOON (CENTRAL COAST, POLAND)
"... Throughout 3 years, a total of 721 various fish species, from the Łebsko Lagoon were examined. The most abundant groups of parasites were Digenea and Crustacea. Metacercariae of Posthodip-lostomum cuticola (Nordmann, 1832) were found only in Cyprinidae (highest prevalence in rudd – 62.5%, and mean i ..."

Population Biology of the Metazoan Parasites Infecting Fishes from Lakes Uba
"... Out of the 48 fishes examined, 40 (83.3%) were infected by 759 parasites, which comprise of trematodes, monogeneans, crustaceans and acanthocephalans. Acanthocephalans and strigeid trematodes were the majority, 23 (47.9%) of all the parasites, while crustaceans, Ergasilus was the minority (20.8%). F ..."

Fungal Rtt109 histone acetyltransferase is an unexpected structural homolog of metazoan p300/CBP
, 2008
"... Rtt109, also known as KAT11, is a recently characterized fungal-specific histone acetyltransferase (HAT) that modifies histone H3 lysine 56 (H3K56) to promote genome stability. Rtt109 does not show sequence conservation with other known HATs and depends on association with either of two histone chap ..."

noteworthy homology to the metazoan p300/CBP HAT domain but exhibits functional divergence, including atypical catalytic properties and mode of cofactor regulation. The structure reveals a buried autoacetylated lysine residue that we show is also acetylated in the Rtt109 protein purified from yeast cells
Evaluating Phylogenetic Informativeness as a Predictor of Phylogenetic Signal for Metazoan, Fungal, and Mammalian Phylogenomic Data Sets
"... Phylogenetic research is often stymied by selection of a marker that leads to poor phylogenetic resolution despite considerable cost and effort. Profiles of phylogenetic informativeness provide a quantitative measure for prioritizing gene sampling to resolve branching order in a particular epoch. T ..."

. To evaluate the utility of these profiles, we analyzed phylogenomic data sets from metazoans, fungi, and mammals, thus encompassing diverse time scales and taxonomic groups. We also evaluated the utility of profiles created based on simulated data sets. We found that genes selected via their informativeness
