The ability to discriminate all species is the ultimate target in barcoding. The Mediterranean basin is a center of origin for legumes and thus they have played a key role in feeding the Mediterranean population. It is also a region with important protected designation of origin and protected geographical indication legumes that provide income in rural areas. We evaluated the use of two ch...
BACKGROUND An understanding of the conservation status of Madagascar's endemic reptile species is needed to underpin conservation planning and priority setting in this global biodiversity hotspot, and to complement existing information on the island's mammals, birds and amphibians. We report here on the first systematic assessment of the extinction risk of endemic and native non-marine Malagasy...
Encouraging crop diversity could be a “win–win” for farmers and biodiversity conservation, if having variety of crops produces the heterogeneity that supports biodiversity, multiple decrease risk to losses due pests, climatic events or market fluctuations, without strongly reducing their incomes. However, data on factors influence decision plant crops, how affects profit, are needed, especially...
Dena Biosphere Reserve located in Iran and is a 550 Biosphere Reserve in the worlds. This research was investigated in the two protected and non-protected areas, in a Dena Biosphere Reserve, Kohkeloye va Boyrahmad province, and central zagros forest, southwest of Iran. Inventory methods designed by systemetic-randomaiz method by use the rectangular plots that were 15×30 meters in the 100×100 m ...
efficiency of the existing protected areas network in conservation of biodiversity is one of the most important challenges of protected areas custodians. despite there are numerous articles on evaluating the efficiency of the protected areas for conserving the habitat and species on national and international scales, in iran this subject has not been studied yet. the aim of the present study is...
Observations of the Sun with the LOWL instrument provide a homogeneous set of solar p-mode frequencies from low to intermediate degree which allows one to determine the structure of much of the solar interior avoiding systematic errors that are introduced when diierent data sets are combined, i.e., principally the eeects of solar cycle changes on the frequencies. Unfortunately, the LOWL data se...
The eeect on p-mode frequencies of changing the near-surface structure of solar models is investigated. As is well known, changes connned to the near-surface region have little eeect on the low-frequency p modes: this is as one would expect from a simple asymp-totic description which shows that these modes have upper turning points located well beneath the photosphere. However, some examples of...

x So far, we have substantially failed to demonstrate that SPT is useful. Also organizations still hesitate to adopt SPI methods.
