Evolutionary change--patterns and processes.

بررسی روند تکامل صفات ریخت شناسی در گونه های ایرانی سردۀ Stachys از نعنائیان براساس توالی هسته ای nrITS

The evolutionary trend of the morphological characters of the genus Stachys in Iran, on the basis of nrITS se-quence data, was investigated. A total of 28 nrITS sequences, representing 26 species of Stachys as well as Betonica of-ficinalis and Melittis mellisophyllum, were obtained from GenBank. Patterns of character evolution were assessed for 10 vegetative and reproductive characters with emp...

Introduction to molecular population genetics

The study of evolutionary biology is commonly divided into two components: study of the processes by which evolutionary change occurs and study of the patterns produced by those processes. By “pattern” we mean primarily the pattern of phylogenetic relationships among species or genes. Studies of evolutionary processes often don’t often devote too much attention to evolutionary patterns, except ...

Developing Adaptive Differential Evolution as a New Evolutionary Algorithm, Application in Optimization of Chemical Processes

Modular Process Patterns Supporting an Evolutionary Software Development Process

Change and evolution of business and technology imply change and evolution of development processes. Besides that for a certain enterprise and/or project we will usually integrate elements from a variety of existing process models, comprising generic standards as well as specific development methods. In this paper we propose a Process Framework which is modularly structured on the basis of the ...

Evolutionary response of landraces to climate change in centers of crop diversity

Landraces cultivated in centers of crop diversity result from past and contemporary patterns of natural and farmer-mediated evolutionary forces. Successful in situ conservation of crop genetic resources depends on continuity of these evolutionary processes. Climate change is projected to affect agricultural production, yet analyses of impacts on in situ conservation of crop genetic diversity an...
