Molecular studies provide very useful information on predicting the evolutionary history of species, species ecology and for describing new species. Dryomys laniger is an alpine that endemic to Anatolia, inhabiting high rocky areas. Its known distribution consists fragmented isolated populations. In order determine a phylogenetic tree was created with one mtDNA two nuDNA. Thirty-one samples wer...

In Iran, the Lamiaceae family is represented by 46 genera, 406 species and 97 infraspecific taxa; of these, 165 taxa are endemic. The distribution of family in Iran covers the whole country but the species number decreases from the centre towards the east, south-east and south. 

The invasion of the giant Madagascar day gecko Phelsuma grandis has increased the threats to the four endemic Mauritian day geckos (Phelsuma spp.) that have survived on mainland Mauritius. We had two main aims: (i) to predict the spatial distribution and overlap of P. grandis and the endemic geckos at a landscape level; and (ii) to investigate the effects of P. grandis on the abundance and risk...

In this research, vascular plants of Bamu National Park (48000 ha.) situated in Fars province were studied. Analyses of all collected plants (450 species) showed that on account of climatic conditions, 94% of them were flowering in spring, also hemicryptophytes and therophytes possess abundant growth form with 39.6% and 23.5%, respectively. Phytogeographically, Irano-Turanian  elements comprise...

BACKGROUND AND AIMS Insufficient pollination is a function of quantity and quality of pollen receipt, and the relative contribution of each to pollen limitation may vary with intrinsic plant traits and extrinsic ecological properties. Community-level studies are essential to evaluate variation across species in quality limitation under common ecological conditions. This study examined whether e...

1. Biological invasions, still occurring worldwide at an alarming rate, are widely acknowledged as threats to the integrity and functioning of ecosystems. In addition to introducing disease, biological invasions have also been linked to sudden increases in the incidence or severity of previously existing diseases. We review and illustrate the potential direct and indirect impacts of introduced ...

Oceanic islands host a disproportionately high fraction of endangered or recently extinct endemic species. We report on species extinctions among endemic Azorean beetles following 97% habitat loss since AD 1440. We infer extinctions from historical and contemporary records and examine the influence of three predictors: geographical range, habitat specialization and body size. Of 55 endemic beet...

In this study, we investigated the chromosome numbers of some endemic species distributed in East and South-East Iran. The mitotic chromosome counts were presented for the first time for six species in three angiosperm families including: Linaria iranica (2n=12), Nanorrhinum campyloceras (2n=18), Chaenorhinum grossecostatum (2n=24) (Plantaginaceae), Gaillonia bruguieri (Rubiaceae) (2n=22), Nepe...
