Under the Superstition Mountains in central Arizona toil those who would rob humankind o f its humanity. These gray, soulless monsters methodically tear away at our meaning, our subjectivity, our essence as transcendent beings. With each advance, they steal our freedom and dignity. Who are these denizens of darkness, these usurpers of all that is good and holy? None other than humanity’s arch-f...
In an earlier paper^ I described the new genus Brooksma from a series of sediments in southeastern Alaska tentatively referred to the upper Silurian. In that paper will be found a brief discussion of the faunal affinities of the series. A more detailed study of the Brooksina fauna together with the famias of lower and liighei horizons strengthens the belief that the formations in question shoul...
obtained during interviews with the ex-inhabitants of an abandoned village near the Igarapé do Urucú (a left affluent of the Rio Sucundurí, along the Serra do Sucundurí) indicates that M. acariensis and another species of marmoset with blackish hairs occur in the area. As M. melanurus has been confirmed as occurring in the Sucundurí Mountains (Noronha, unpubl. data), it is possible that these s...
The variation of forest types across Virginia reflects the diverse physiography of the state. From the sandy, low-elevation soils of the Coastal Plain to the dry, rocky soils on the southwestern slopes of the Appalachian Mountains, Virginia has one of the most diverse landscapes in the East (Fleming et al. 2006). Most forests in this area have been heavily influenced by anthropogenic disturbanc...
The subalpine zones on the mountains south of the Tohoku mountains in the Japanese Islands are normally occupied by coniferous forests dominated by Abies mariesii, A. veitchii, Picea jezoensis var. hondoensis and Tsuga diversifolia. But there are many mountains where the subalpine coniferous forest does not exist; the thermometrical subalpine zones on such mountains are replaced by subalpine an...
The Tienshan Mountains, with its status as "water tower", is the main water source and ecological barrier in Central Asia. The rapid warming affected precipitation amounts and fraction as well as the original glacier/snowmelt water processes, thereby affecting the runoff and water storage. The ratio of snowfall to precipitation (S/P) experienced a downward trend, along with a shift from snow to...
Background & Objectives: Zagros Mountains, which are between the flatlands of Mesopotamia and the Iranian plateau, surround the western border of the country. This region was the cradle of great civilizations like Mesopotamia and Elam. This study aimed to test the boundary role of the Zagros Mountains in the genetic structure of the region through evaluating the paternal lineages inheritance ...
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...
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...
