Phylogeographic patterns in wide-ranging species in southern Africa remain largely unexplored, especially in areas north of South Africa. Here, we investigate population structuring, demographic history, and the colonization pattern of the western rock skink (Trachylepis sulcata), a rock-dwelling species with a range extending from southwestern South Africa into Angola. Using 1056 bp from the m...
مطالعه حاضر، بر پایه بررسی نمونه های جمع آوری شده از نواحی پراکنش گونه های مربوط به زیرجنس schedonorus از ایران و همچنین، مشاهده نمونه های موجود در هرباریوم های وین و برلین، شامل نمونه های تیپ، انجام گرفته است. بر اساس نتایج حاصل از این تحقیق، زیرجنس schedonorus در ایران دارای سه گونه festuca arundinacea، f. gigantean و pratensis f. است. همچنین، مشخص شد که گونه f. arundinacea در ایران دارای دو ...
The heating of the solar chromosphere and corona is a long-standing puzzle in solar physics. Hinode observations show the ubiquitous presence of chromospheric anemone jets outside sunspots in active regions. They are typically 3 to 7 arc seconds = 2000 to 5000 kilometers long and 0.2 to 0.4 arc second = 150 to 300 kilometers wide, and their velocity is 10 to 20 kilometers per second. These smal...
Festuca rubra is an abundant supratidal grass on sub-arctic James Bay (Canada) shorelines, forming extensive near-monocultures that are used as forage by nesting and migrating geese. Studies at other, more northern North American locations have shown grubbing by geese can have severe consequences for intertidal and supratidal marshes, but these studies have focussed on plant communities that di...
New combinations and names are here validated for ten grass (Poaceae) taxa in California for the forthcoming revision of The Jepson Manual. In addition, guided by recent molecular phylogenetic studies, ten non-California grass species are here transferred to Muhlenbergia (Chloridoideae: Cynodonteae) to achieve monophyly of the genus. Lolium, long known to be phylogenetically nested within Festu...
Rickettsia hoogstraalii is a tick-associated member of the spotted fever group rickettsiae that is geographically widely distributed. We report here the draft genome of R. hoogstraalii strain Croatica(T) (=DSM 22243 = UTMB 00003), which was isolated from Haemaphysalis sulcata ticks collected in Croatia.
Chloroplast genome sequences are of broad significance in plant biology, due to frequent use in molecular phylogenetics, comparative genomics, population genetics, and genetic modification studies. The present study used a second-generation sequencing approach to determine and assemble the plastid genomes (plastomes) of four representatives from the agriculturally important Lolium-Festuca speci...
