A structural phylogenetic map for chloroplast photosynthesis
Trends in Plant Science, 2011Chloroplasts are cytoplasmic organelles and the sites of photosynthesis in eukaryotic cells. Advances in structural biology and comparative genomics allow us to identify individual components of the photosynthetic apparatus precisely with respect to the subcellular location of their genes.

A Phylogenetic and Structural Analysis of Truncated Hemoglobins
Journal of Molecular Evolution, 2006Truncated hemoglobins (trHbs) are heme proteins found in bacteria, plants, and unicellular eukaryotes. They are distantly related to vertebrate hemoglobins and are typically shorter than these by 20-40 residues. The multiple amino acid deletions, insertions, and replacements result in distinctive alterations of the canonical globin fold and a wide ...

Journal of Ecology, 2007
1 Analysing the phylogenetic structure of natural communities may illuminate the processes governing the assembly and coexistence of species in ecological communities. 2 Unifying previous works, we present a statistical framework to quantify the phylogenetic structure of communities in terms of average divergence time between pairs of individuals or ...

Separating the determinants of phylogenetic community structure
Ecology Letters, 2007Abstract The role of competition in forbidding similar species from co‐occurring has long been debated. A difficulty in identifying this repulsion of similar species is that similar species share similar environmental requirements and hence show an attraction to communities where these requirements are met.

Structuralism in Phylogenetic Systematics
Biological Theory, 2010Systematics based solely on structuralist principles is non-science because it is derived from first principles that are inconsistent in dealing with both synchronic and diachronic aspects of evolution, and its evolutionary models involve hidden causes, and unnameable and unobservable entities. Structuralist phylogenetics emulates axiomatic mathematics

A framework for metacommunity analysis of phylogenetic structure
Ecology Letters, 2010Ecology Letters (2010) 13: 587–596AbstractIt is well known that species evolutionary history plays a crucial role in community assembly. Here, we offer a formal analytical framework to integrate in metacommunity analysis the species’ phylogeny with their functional traits and abundances.

Analysing Phylogenetic Structures
2018This chapter shows how multivariate approaches can be used for investigating phylogenetic structures, focussing on methods for measuring, testing, accounting for and describing a phylogenetic signal.

The Fine Structure of Galls in Phylogenetic Networks
INFORMS Journal on Computing, 2004A phylogenetic network is a generalization of a phylogenetic tree, allowing properties that are not tree-like. With the growth of genomic data, much of which does not fit ideal tree models, there is greater need to understand the algorithmics and combinatorics of phylogenetic networks (Posada and Crandall 2001, Schierup and Hein 2000).Wang et al. (2001)

The Phylogenetic Structure of the Genus Streptosporangium
Systematic and Applied Microbiology, 1996Summary The phylogenetic structure of the genus Streptosporangium was determined by comparative 16S rDNA sequence analysis of 26 Streptosporangium strains, including the type strains of all validly-described Streptosporangium species. Streptosporangium forms a phylogenetically coherent genus and appears to be most closely related to members ...

Phylogenetic variation in the primary structure of hemoglobins
Journal of Cellular Physiology, 1966The amino acid compositions of homologous tryptic peptides, as well as the amino acid sequences of complete peptide chains, are compared in hemoglobins of different species. Special attention is given to the analyses of mammalian and fish hemoglobins.
