Mountains are among the most prominent of geographic features (Smith and Mark, 2001). They also have social and emotional significance, serving as objects of worship in many cultures and as landmarks in many more. And, of course, mountains provide challenges to adventurers and scientists alike. Thus it should come as no surprise that geomorphologists and other environmental scientists have been...

The Hajar Mountains of south-eastern Arabia form an isolated massif surrounded by the sea to the east and by a large desert to the west. As a result of their old geological origin, geographical isolation, complex topography and local climate, these mountains provide an important refuge for endemic and relict species of plants and animals. With 19 species restricted to the Hajar Mountains, repti...

middle jurassic fluvio-deltaic and turbiditic mudstones of the kashafrud formation, are important hydrocarbon sources in the gas-rich kopet-dagh basin, northeast iran. clay mineral assemblages are important for interpretation of sediment provenance and for understanding burial diagenetic cementation in sandstones. the clay mineral assemblages in mudrocks in two areas, saleh-abad and senjedak, w...

ABSRTACT The Appalachian Mountains are arguably home to the highest degree of amphibian diversity in the world, particularly caudate (salamander) biodiversity. Despite the high degree of amphibian endemism in the Appalachians, several regions remain unsurveyed for amphibian species. In addition to this knowledge gap, we are in the midst of alarming amphibian biodiversity loss. Thus, it is of th...

The cryosphere in the McMurdo Sound region has undergone significant modifications during the last 1 Ma. Consequently, the sedimentary sequences underlying the modern McMurdo Ice-Shelf provide geological data to reconstruct variations in transport and depositional mechanisms of terrigenous material due to variations in ice sheet extension, grounding line position and main icestream flow directi...

Most research on vegetation in mountain ranges focuses on elevation gradients as climate gradients, but elevation gradients are also the result of geological processes that build and deconstruct mountains. Recent findings from the Luquillo Mountains, Puerto Rico, have raised questions about whether erosion rates that vary due to past tectonic events and are spatially patterned in relation to el...

This study presents the nannostratigraphy and nannofossil events in the lower boundary of Kalat Formation in the East and West of the Kopeh- Dagh basin. The Kalat Formation comprises of coarse grained detritus limestone with subordinate sandstone intercalations. In the current study, six sections have been chosen in the East and West of the basin which are as follow: Dobaradar section, Kalat se...

In late 1986 an official deer hunting regime in the Murchison Mountains, Fiordland, was compared with two commerical aerial hunting regimes in the adjacent Stuart Mountains by measuring the density of deer faecal pellet groups. Overall densities in the Stuart Mountains were twice those in the Murchison Mountains. Official hunting appeared to be more effective than commercial hunting at reducing...

Two new species of Phlugidia (Orthoptera: Tettigoniidae: Meconematinae) are described from the Eastern Arc Mountains of Tanzania. P. planicercus Hemp n. sp. occurs in lowland forest at the foothills of the Uluguru Mountains, while P. ob- tusicercus Hemp n. sp. was collected in the Nguru Mountains. A key to Phlugidia species is provided.
