Phylogenetic niche conservatism, phylogenetic signal and the relationship between phylogenetic relatedness and ecological similarity among species

open access: yesEcology Letters, 2008
Ecologists are increasingly adopting an evolutionary perspective, and in recent years, the idea that closely related species are ecologically similar has become widespread. In this regard, phylogenetic signal must be distinguished from phylogenetic niche

BOOL-AN: A method for comparative sequence analysis and phylogenetic reconstruction [PDF]

open access: yes, 2009
A novel discrete mathematical approach is proposed as an additional tool for molecular systematics which does not require prior statistical assumptions concerning the evolutionary process.

Towards a Taxonomically Intelligent Phylogenetic Database

open access: yes, 2007
This note outlines some of the key intellectual obstacles that stand in the way of creating a usable phylogenetic database. These challenges include the need to accommodate multiple taxonomic names and classifications, and the need for tools to query ...

Phylogenetic support values are not necessarily informative : the case of the Serialia hypothesis (a mollusk phylogeny) [PDF]

open access: yes, 2009
Background: Molecular phylogenies are being published increasingly and many biologists rely on the most recent topologies. However, different phylogenetic trees often contain conflicting results and contradict significant background data. Not knowing how

The role of edaphic environment and climate in structuring phylogenetic pattern in seasonally dry tropical plant communities

open access: yes, 2015
This study was made possible through the kind financial support of the São Paulo Research Foundation - http://fapesp.br/en (Fundação de Amparo à Pesquisa do Estado de São Paulo - Fapesp 2013/15280-9).Seasonally dry tropical plant formations (SDTF) are ...

Testing robustness of relative complexity measure method constructing robust phylogenetic trees for Galanthus L. Using the relative complexity measure [PDF]

open access: yes, 2013
Background: Most phylogeny analysis methods based on molecular sequences use multiple alignment where the quality of the alignment, which is dependent on the alignment parameters, determines the accuracy of the resulting trees.

Phylogenetic Codivergence Supports Coevolution of Mimetic Heliconius Butterflies

open access: yes, 2012
The unpalatable and warning-patterned butterflies _Heliconius erato_ and _Heliconius melpomene_ provide the best studied example of mutualistic Müllerian mimicry, thought – but rarely demonstrated – to promote coevolution.

Molecular phylogenetic evaluation of classification and scenarios of character evolution in calcareous sponges (Porifera, Class Calcarea). [PDF]

open access: yes, 2012
Calcareous sponges (Phylum Porifera, Class Calcarea) are known to be taxonomically difficult. Previous molecular studies have revealed many discrepancies between classically recognized taxa and the observed relationships at the order, family and genus ...

Predicting functional gene links from phylogenetic-statistical analyses of whole genomes

open access: yes, 2005
An important element of the developing field of proteomics is to understand protein-protein interactions and other functional links amongst genes. Across-species correlation methods for detecting functional links work on the premise that functionally ...
