21 تاکسون شامل 18 گونه calligonum و 3 گونه pteropyrumبعنوان درون گروه به اضافه 2 گونه از atraphaxis، بعنوان برون گروه با استفاده از30 صفت ریخت شناسی مورد مطالعه قرار گرفتند. در هر دو آنالیز بدون وزن دهی و با وزن دهی (توسط شاخص سازگاری تصحیح شده)، calligonum و pteropyrum تشکیل کلاد مجزا داده اند. هر دو بخشه pterococcus و) calligonum شامل بخشه تک گونه ای (calliphysa از جنس calligonum تک تبارند....
Wood anatomy is an important source of systematically informative character information that can and should be used in cladistic phylo genetic analyses ofrelationships in flowering plants. However, the re sults ofa cladistic analysis are only as good as the characters and obser vations, which together comprise the data set that is analyzed. The goal of this paper is to address the former of ...
The distinctly non-random diversity of organismal form manifests itself in discrete clusters of taxa that share a common body plan. As a result, analyses of disparity require a scalable comparative framework. The difficulties of applying geometric morphometrics to disparity analyses of groups with vastly divergent body plans are overcome partly by the use of cladistic characters. Character-base...

The chorionic structure of sixteen pentatomid species is described. Morphological patterns in different taxonomic levels are discussed. In addition, egg characters useful in cladistic analyses are listed, and some of those characters are tested for congruence with two cladistic analyses previously conducted within Pentatomidae. Descriptive studies were conducted with Banasa induta, Capivaccius ...
In case-control studies, genetic associations for complex diseases may be probed either with single-locus tests or with haplotype-based tests. Although there are different views on the relative merits and preferences of the two test strategies, haplotype-based analyses are generally believed to be more powerful to detect genes with modest effects. However, a main drawback of haplotype-based ass...
Rhynchocephalians are a group of lizard-like diapsid reptiles that were very diverse during the Mesozoic but now restricted to single extant genus in New Zealand. Recent cladistic analyses ha...
