A phylogenetic hypothesis, in short a phylogeny, is an implicit hypothesis of evolutionary relationships. Such hypotheses can be erected based on intuition, as that in Figure 6 by Haeckel,100 but are in a modern systematic or evolutionary biology context a result of careful analysis of scientific...
10–12]). Members of the currently recognized families Tripterygiidae, Blenniidae, Labrisomidae, Clinidae and Chaenopsidae are consistently included, but other families have been added depending on the definition of “true” blennies [11,13–16]. A widely accepted concept of a monophyletic...
abundance level. This is probably a reason why many mediation methods for microbiome data focus more on hypothesis testing than estimation. The test results provide a scan of high-dimensional microbial composition and generate candidates for downstream validation studies and mechanistic experiments. Results...
The tremendous diversity in biology, morphology and life history of the organisms known as the algae, as well as their polyphyletic evolutionary history, make a simple, practical definition of the group impossible (see, for example, Mattox and Stewart, 1984; Bold and Wynne, 1985; van den Hoek...
The assembly of reliable and complete protein-protein interaction (PPI) maps remains one of the significant challenges in systems biology. Computational methods which integrate and prioritize interaction data can greatly aid in approaching this goal. We
(2004) and presents a more detailed molecular phylogeny for Hyphoderma and Hypochnicium. The objective is to explore the implied heterogeneity of Hyphoderma, to arrive at a better definition of Hyphoderma and Hypochnicium, and to make the necessary nomenclatural changes. ...
(ii) To test whether gyrodactylids with low host-specificity interfered with the analyses, we removed gyrodactylids with the top 15% SPSivalues (see the definition of SPSiin the “Host specificity” section), and their unique hosts, from the P18SHMITO dataset. This subdataset was named “...
Rab7b and Rab7c proteins are also placed among very divergent sequences of excavates and amoebozoans, likely as a result of the LBA. Considering taxonomic distribution of Rab9 proteins we should expect that they diverged from Rab7 proteins before radiation of metazoans at the level of common anc...
Australopiths: a general term typically used in reference to species ofAustralopithecusandParanthropus. This is not a formal taxonomic name and therefore does not need to adhere to the strict rules of biological nomenclature. Biological species concept: This is the most commonly used definition ...
2015, Current Biology Citation Excerpt : Originally classified as a thraustochytrid based on its morphology, C. limacisporum has been unstably placed within the Opisthokonta in all molecular phylogenies to date because of the scarce molecular data available [8–11]. In order to improve the op...
