Petrography, Major and Trace Elemental Geochemistry of the Ordovician-Silurian Siliciclastics in North of Tabas Block, Central Iran: Implications for Provenance and Paleogeography

The upper part of Shirgesht (UPS) and lower part of Niur (LPN) formations (Ordovician-Silurian) consist of sandstone, shale and limestone, respectively. The petrography and geochemical analysis conducted to evaluate provenance of siliciclastic deposits in order to understand the paleogeography of Central Iran during the Early Paleozoic time. This study shows that quartz and K-feldspar are the m...

Phylogeny of gazelles in some islands of Iran based on mtDNA sequences: Species identification and implications for conservation

Different species of gazelles are among the most endangered mammals on the Asian steppes and occur in the central, southern and northwestern regions of Iran. The previous conservation efforts in this region have been incomplete due to confusion about the phylogenetic relationship among various populations. So that, different conservation programs such as ex-situ breeding and transfer of captive...

The mismeasure of islands: implications for biogeographical theory and the conservation of nature

The importance of islands for our understanding of evolution, ecology, and biogeography cannot be overstated. Although MacArthur & Wilson’s (1967) classic monograph and foundation for the Equilibrium Theory of Island Biogeography (ETIB) has been largely invalidated and superseded by new field data and more realistic concepts, there are still key aspects of the ETIB paradigm that continue to inf...
