The discovery of two new Frasnian species of the subfamily Asteropyginae, Bradocryphaeus kermanensis and Radiopyge hamedii, in the Haruz section north of Kerman, east-central Iran, demonstrates for the first time the presence of North Gondwanan trilobites in this region. The two new species provide a link between faunas from Afghanistan to the east and the Alborz Mountains in north Iran. The recognition of R. hamedii confirms the validity of Radiopyge Farsan, hitherto known only from Afghanistan, as well as the presence in some Frasnian Asteropyginae of six pairs of lateral pygidial spines.  相似文献

The conservation status of the koala in Australia is not a homogeneous entity but is subject to regional variation according to the predicament of each population with respect to disease and habitat availability. Habitat is the primary factor affecting koala population dynamics in both critical decline and expansion. Key koala management and planning decisions necessitate a regional identification of potentially suitable koala habitat. The environmental factors constituting preferred koala habitat were identified and existing GIS databases used to combine Eucalyptus species preferred and utilised by koalas with soil properties to predict optimal, sub-optimal and unsuitable koala habitat in the southern Mt. Lofty Ranges. The methodological framework is flexible and particularly suited to regional koala management in Australia.  相似文献
