We here explore the use of a Bayesian approach to island biogeography for disentangling the evolutionary origins of a continental-scale floristic pattern, the enigmatic 'Rand Flora'. The existence of disjunct distributions across many plant lineages between Macaronesia-northwest Africa, Horn of Africa-southern Arabia and east-south Africa has long intrigued botanists, but only now can we start ...

flora of jahanbin mountain area in chaharmahal and bakhtiari province, located between shahrekord and hafshejan cities, with 12’187 hectares and 2’150 to 3’300 m elevation above sea level, is investigated. vegetation of this area comprises of 273 species, 189 genera and 42 families. asteraceae (37 species, 13.5%), poaceae (31 species, 11.3%) and fabaceae (25 species, 9.1%) were the most importa...

The species composition, systematics, and ecological-coenotic features of the flora local landscape Feofaniya have been analyzed. In total, 650 vascular plants identified in this area, representing 337 genera 94 families. It was found that natural component represents 48.8 %, synanthropic 51.2 %. aboriginal fraction includes 469 from 252 77 Adventive is represented by 181 131 51 tends to broad-...

Many habitat specialist species are originally composed of small, discontinuous populations because their habitats are naturally fragmented or patchy. They may have suffered the long-term effects of natural patchiness. Mediterranean heathlands, a representative habitat in the Strait of Gibraltar region, are associated with nutrient-poor, acidic sandstone soils. Sandstone soil patches in the Afr...

We examined the phylogenetic history of Linaria with special emphasis on the Mediterranean sect. Supinae (44 species). We revealed extensive highly supported incongruence among two nuclear (ITS, AGT1) and two plastid regions (rpl32-trnL(UAG), trnS-trnG). Coalescent simulations, a hybrid detection test and species tree inference in *BEAST revealed that incomplete lineage sorting and hybridizatio...

Abstract In terms of plant diversity, the Mediterranean Basin is world’s second richest hotspot, and one most important locations on planet for endemic species. Despite widespread acknowledgment region’s global importance an up-to-date list endemics still unavailable. The available data are frequently insufficient or out date at both whole national levels. Therefore, present study aimed delimit...

The goal of The William and Flora Hewlett Foundation‟s Global Development Program is to improve the income and well-being of people living on less than $2 per day. The Program seeks to promote specific changes that will help reduce extreme poverty in a set of target countries. To achieve this goal, the Global Development Program will invest in three complementary drivers of economic growth: (1)...
