بر پایه جمع آوری های تازه ای که در سالهای اخیر توسط گروه گیاه شناسان هرباریوم های مختلف کشور از جمله قهرمانی و جوادی از تبریز؛ طیبی خرمی و حاتمی از فارس ؛ معروفی از کردستان؛ جوهرچی از خراسان ؛ نعمتی از کرمانشاه؛ موسوی از زنجان و نوروزی از اصفهان بعمل آمده است. تعداد 8 گونه جدید معرفی می گردد. گونه های جدید به بخشهای مختلف تعلق داشته که برای هر گونه دیاگنوز و شرح و برای تعدادی از آنهادرباره جایگ...
The synthesis of silaheterocycles through the first examples of an intramolecular silene Diels-Alder reaction is described.
Chiral Symmetry is important in a lot of situations. In this talk I will restrict myself to consequences of Chiral Symmetry for the strong interaction. The subject is very broad as can be judged from the lectures and review articles. In its modern form it was founded by Weinberg and Gasser and Leutwyler. I will discuss a few of the basics in sects. 2, 3, 4. The applications to ππ scattering (se...
This paper fortifies and defends the so called Sufficiency Argument (SA) against Classical Invariantism. In Sect. 2, I explain the version of the SA formulated but then rejected by Brown (2008a). In Sect. 3, I show how cases described by Hawthorne (2004), Brown (2008b), and Lackey (forthcoming) threaten to undermine one or the other of the SA’s least secure premises. In Sect. 4, I buttress one ...
The cosmopolitan fungal genus Alternaria consists of multiple saprophytic and pathogenic species. Based on phylogenetic and morphological studies, the genus is currently divided into 26 sections. Alternaria sect. Alternaria contains most of the small-spored Alternaria species with concatenated conidia, including important plant, human and postharvest pathogens. Species within sect. Alternaria h...
Microbotryum violaceum (anther-smut) from Silene caroliniana and S. virginica produced promycelia that frequently appeared to contain more than three cells according to the number of septations. This is in contrast to samples from S. latifolia and to previous descriptions of this species. Apparent four-celled promycelia contained three nucleate cells and one anucleate zone. Anucleate zones were...
My purpose here is to provide a coherent account of inclusive fitness techniques, accessible to a mathematically literate graduate student in evolutionary biology, and to relate these to standard one-locus genetic models. I begin in Sect. 2 with a general formulation of evolutionary stability; in Sect. 3 and Sect. 4 I interpret the basic stability conditions within genetic and inclusive fitness...
جنس silene l. بزرگترین جنس از خانواده caryophyllaceae است. این جنس در حدو 750 گونه در سرتاسر دنیا دارد. بیشترین پراکنش آن در نیمکره شمالی، اروپا، آسیا و آفریقای شمالی است. آسیای جنوبغربی و منطقه جنوب بالکان دو مراکز اصلی تنوع زیستی این جنس در دنیا به شمار می آیند. 141 گونه از این جنس در محدوده جغرافیایی ایران میرویند که حدود 35 گونه آن انحصاری ایران هستند. مطالعه سیستماتیکی بر روی 195 جمعیت م...
Large and diverse genera, such as Silene need more reliable morphological traits for the credible identification and delimitation of the species. Despite the fact that the type of indumentum among the species of Silene had been addressed in most available revisions, monographs and floristic studies, the trichome-based features and their adaptational importance have not been investigated explici...
