"principles of Phylogenetics: Ecology

چکیده
I. Continuous characters – ancestral states Many traits of interest are measured on continuous or metric scales – size and shape, physiological rates, etc. Continuous traits are often useful for species identification and taxonomic descriptions; historically, they were also used in phylogenetic analysis through the use of clustering algorithms that can group taxa based on multivariate phenetic similarity. With the advent of cladistics and the proliferation of molecular data, reconstruction has shifted (almost) entirely to discrete trait analysis.

Using the Component Model of Sustainable Landscape for the Quality Assessment of Urban Natural Public Spaces: A Case Study from Tehran’s River-valleys
Ecological destruction in human-dominated landscapes has significant impacts on environment sustainability internationally. Landscape planning can play a role in mitigating the effects of human-related activities. One element of landscape planning involves the analysis of the biological, spatial and social arrangement of areas in an urban environment and identifying characteristics that are und...

متن کاملAn introduction to phylogenetic analyses and modelling in ecology
Phylogenetic systematics seeks to describe and reconstruct the evolutionary relationships among and between organisms making use of molecular data. This field has become immensely popular in recent years, with the associated computational demands growing in leaps and bounds. Here, we review the progress made in statistical phylogenetics, compare the various methods and highlight the recent tren...
