Computational Analysis of the Fungal and Metazoan Groups of Heat Shock Proteins
"... Biological applications of computers are vastly increasing as computer technology rapidly improves. One such application is the visualization of the three-dimensional structure of certain proteins. There is a direct correlation ..."

Near Intron Pairs and the Metazoan Tree
"... Gene structure data can substantially advance our understanding of metazoan evolution and deliver an independent approach to resolve conflicts among existing hypotheses. Here, we used changes of spliceosomal intron positions as novel phylogenetic marker to reconstruct the animal tree. This kind of d ..."

deep metazoan phylogeny. All groupings that were obtained with more than 80 % bootstrap support are consistent with currently supported phylogenetic hypotheses. This includes monophyletic Chordata, Vertebrata, Nematoda, Platyhelminthes and Trochozoa. Several other clades such as Deuteros
Some unusual small-subunit ribosomal RNA sequences of metazoans
- Am. Museum Novitates
, 2001
"... The SSU rRNA gene is one of the most widely utilized loci for phylogenetic inference among eukaryotic organisms. Although they have an average length of 1800 to 1900 bp, several unusually large 18S rDNA sequences have been reported. After examining GenBank sequences and 180 new 18S rRNA sequences fr ..."

from several metazoan groups, we report many other extraordinary sequences ranging between ca. 1350 bp (in symphylan myriapods) to ca. 3300 bp (in some strepsipteran insects). Myriapods are particularly interesting, having inde-pendently evolved extraordinary sequences in the four classes (Chilopoda
Phylogenetic Context and Basal Metazoan Model Systems 1
"... SYNOPSIS. In comparative studies using model organisms, extant taxa are often referred to as basal. The term suggests that such taxa are descendants of lineages that diverged early in the history of some larger taxon. By this usage, the basal metazoans comprise just four phyla (Placozoa, Porifera, C ..."

Early metazoan evolution: reconciling paleontology and molecular biology
- Am. Zool
, 1998
"... SYNOPSIS. Molecular "clocks " are now widely accepted as pointing to a protract-ed, but cryptic, history of pre-Ediacaran metazoan evolution. The inhabitants of this interval (ca. 1300-600 Myr ago) are usually envisaged as equivalent to either planktotrophic larvae or the meiofauna. Reasse ..."

. Reassessment of the evidence, however, suggests that this pre-Ediacaran history was neither deep nor was represented by analogues of microscopic living metazoans. The origination of this Kingdom may have been no earlier than ca. 650 Myr, and the earliest forms emerged from the Metazoa-Fungi-Mycetozoa stem-group
Control of developmental regulators by Polycomb in human embryonic stem cells. Cell 125: 301–313
, 2006
"... Polycomb group proteins are essential for early development in metazoans, but their contributions to human development are not well understood. We have mapped the Polycomb Repressive Complex 2 (PRC2) subunit SUZ12 across the entire nonrepeat portion of the genome in human embryonic stem (ES) cells. ..."

The Evolutionary Relationship between Microbial Rhodopsins and Metazoan Rhodopsins
"... Rhodopsins are photoreceptive proteins with seven-transmembrane alpha-helices and a covalently bound retinal. Based on their protein sequences, rhodopsins can be classified into microbial rhodopsins and metazoan rhodopsins. Because there is no clearly detectable sequence identity between these two ..."

groups, their evolutionary relationship was difficult to decide. Through ancestral state inference, we found that microbial rhodopsins and metazoan rhodopsins are divergently related in their seven-transmembrane domains. Our result proposes that they are homologous proteins and metazoan rhodopsins
EVOLUTION & DEVELOPMENT 5:4, 346–359 (2003) Conflicting phylogenetic signals at the base of the metazoan tree

Despite a number of recent molecular studies and a rich fossil record of sponges and cnidarians, the evolutionary relationships of the early branching metazoan groups to each other and t ..."

Regulation of bacterial biomass and community structure by metazoan and protozoan predation

, 2001

We performed food web manipulation experiments in three eutrophic Daphnia-dominated ponds, to compare the predation impact on planktonic bacteria exerted by metazoan and protozoan bacterial consumers. We analyzed the bacterial morphological composition by image analysis and the taxonomic composition ..."

The ecology of marine microbenthos. 1. The quantitative importance of ciliates as cornpared with Metazoans in various types of sediments

, 1967
"... ABSTRACT An investigation of the quantitative importance of protozoans -especially ciliates -has been undertaken in Scandinavian waters. Ciliates were found in numbers from 10 6 to 4 X 10 7 individuals per m' representing 0.03-2.3 grammes wet weight per m'. Highest numbers were found in f ..."

In the detritus layers which cover clayey and muddy sediments ciliates are few in number and play a small role compared with metazoan groups, such as nematodes, which may sometimes be as numerous as ciliates.
