Integrating alpha, beta, and phylogenetic diversity to understand anuran fauna along environmental gradients of tropical forests in western Ecuador

open access: yesEcology and Evolution, 2019
The study of current distribution patterns of amphibian species in South America is of particular interest in areas such as evolutionary ecology and conservation biology.

Mixed-up Trees: the Structure of Phylogenetic Mixtures [PDF]

open access: yesBulletin of Mathematical Biology, 2008
In this paper we apply new geometric and combinatorial methods to the study of phylogenetic mixtures. The focus of the geometric approach is to describe the geometry of phylogenetic mixture distributions for the two state random cluster model, which is a generalization of the two state symmetric (CFN) model.

Latitudinal gradients of angiosperm plant diversity and phylogenetic structure in China’s nature reserves

open access: yesGlobal Ecology and Conservation, 2023
The mechanisms underlying latitudinal and longitudinal patterns in species diversity remain a central issue in ecology and are vital for effective biodiversity conservation.

Structural Phylogenetics and the Reconstruction of Ancient Language History [PDF]

open access: yesScience, 2005
The contribution of language history to the study of the early dispersals of modern humans throughout the Old World has been limited by the shallow time depth (about 8000 ± 2000 years) of current linguistic methods. Here it is shown that the application of biological cladistic methods, not to vocabulary (as has been previously tried) but to language ...

Protein Structural Phylogenetics

open access: yesGenome Biology and Evolution
Abstract Protein structural phylogenetics is an interdisciplinary branch of molecular evolution that (i) uses 3D structural data to trace evolutionary histories, and (ii) uses these evolutionary relationships to explore the diversity of protein structures and their ancestral functions.

Modern Climate and Soil Properties Explain Functional Structure Better Than Phylogenetic Structure of Plant Communities in Northern China

open access: yesFrontiers in Ecology and Evolution, 2020
Examination of the mechanisms of the plant community assembly at a geographical scale is an interesting topic in ecology and biogeography, which are of great significance for the understanding of species coexistence and biodiversity conservation.

Fast Structural Search in Phylogenetic Databases

open access: yesEvolutionary Bioinformatics, 2005
As the size of phylogenetic databases grows, the need for efficiently searching these databases arises. Thanks to previous and ongoing research, searching by attribute value and by text has become commonplace in these databases. However, searching by topological or physical structure, especially for large databases and especially for approximate ...

Drivers of Shrub Community Assembly in Semi-Arid Ecosystems: Integrated Evidence from Environmental Stress on the Western Loess Plateau

open access: yesBiology
Shrub communities play an irreplaceable role in maintaining ecological security in the stressed habitat areas of Northwest China. In these areas, multiple types of shrublands coexist simultaneously. Their diversity levels and community assembly processes

Phylogenetic and structural analysis of Hydra ADAR

open access: yesArchives of Biochemistry and Biophysics
Adenosine deaminases acting on RNAs (ADARs) perform adenosine-to-inosine (A-to-I) RNA editing for essential biological functions. While studies of editing sites in diverse animals have revealed unique biological roles of ADAR editing including temperature adaptation and reproductive maturation, rigorous biochemical and structural studies of these ADARs
