Although native to the southeastern United States, the red swamp crayfish (Procambarus clarkii) has become established worldwide through accidental and intentional actions by humans. In the Santa Monica Mountains of southern California, the presence of the omnivorous crayfish is associated with the absence or reduced abundance of native amphibians. The original source of P. clarkii in southern ...
This study compiles and interprets three-dimensional Weather Surveillance Radar-1988 Doppler (WSR88D) data during a 2.5-yr period and examines the typical orographic effects on precipitation mainly associated with winter storms passing over coastal northern California. The three-dimensional mean reflectivity patterns show echo structure that was generally stratiform from over the ocean to inlan...
the genus trachylepis fitzinger, 1843 encompasses two-three species in iran: trachylepis vittata (olivier, 1804) distributed in western iran, west of the zagros mountains; t.septemtaeniata (reuss, 1834) in southern regions of the zagros mountains and t. aurata transcaucasica chernov, 1926 from northern to central parts of the zagros mountains. for study of geographic variation in the latter two...
The first four words of the title of this article match the title of Section 4 of Ron Smith’s (1979) review, “The Influence of Mountains on the Atmosphere”. Via a comprehensive survey of the literature available 25 years ago, Smith identified the key ways in which mountains potentially can affect precipitation. Little has changed regarding his conclusions. However, little factual information wa...

The cartographic depiction of high mountain areas has always been a challenge to generations of cartographers, surveyers and geographers. The maps resulting from this work contain a wide range of information, which are diffi cult to understand for a non-expert community. Hence the fascination of high mountain areas was up to now mostly reserved to experts and climbers. New techniques in Compute...
O nce you get to Swanton Pacific Ranch in the coastal mountains north of Santa Cruz, it's pretty obvious the 3,200-acre spread offers many things you just won't find at Cal Poly: trees, for one thing. A whole forest full of them 2,100 acres to be exact. They cover steep mountain slopes and march in tall columns down to grassy meadows. A river runs through it: Scott Creek and its tributaries. "T...
Protected areas in mountains are regularly in the focus of international efforts to conserve the environment and enable sustainable development. The following article analyses the current extend of protection in mountainous versus non-mountainous areas, sheds light on the rationales behind the establishment of mountain protected areas, and proposes directions for future endeavours in protecting...
The Kura-Araxes cultural tradition existed in the highlands of the South Caucasus from 3500 to 2450 BCE (before the Christian era). This tradition represented an adaptive regime and a symbolically encoded common identity spread over a broad area of patchy mountain environments. By 3000 BCE, groups bearing this identity had migrated southwest across a wide area from the Taurus Mountains down int...
