– This study analysed the spatial structure of the Carpathian Mountains, in Central Europe, considering it a unit that extends across national boundaries, and assessing the suitability of areas were wolves could be conserved. Physical characteristics of the area were extracted from NOAA-AVHRR NDVI. A set of 9 images from different periods of the year was used to parameterise the phenological va...

The paper begins with the question “Do mountains exist?” It shows that providing an answer to this question is surprisingly difficult, and that the answer which one gives depends on the context in which the question is posed. Mountains clearly exist as real correlates of everyday human thought and action, and they form the archetype for geographic objects. Yet individual mountains lack many of ...

The total number of brown bears (Ursus arctos) in Europe is presently about 50,000 (about 14,000 outside Russia), within an area of more than 2.5 million km (800,000 km outside Russia). About 37,500 bears are found in the northeastern European population; 8,100 in the Carpathian Mountains; 2,800 in the Alps–Dinaric–Pindos; 1,000 in Scandinavia; 520 in the Rila–Rhodope Mountains; 200 in the Star...

Forests of the South are very diverse and productive. Included among southern forests are the boreal sprucefir forests of the highest mountain peaks of the Blue Ridge Mountains to the lowest bottomland hardwoods on flood-deposited soil with elevations near sea level. In between are the diverse upland hardwood stands in northerly mountainous areas of the South and southern pines and hardwnocls a...

The change in snow cover under climate change is poorly understood in Tianshan Mountains. Here, we investigate the spatiotemporal characteristics and trends of snow-covered area (SCA) and snow-covered days (SCD) in the Tianshan Mountains by using the cloud-removed MODIS fractional snow cover datasets from 2001–2015. The possible linkage between the snow cover and temperature and precipitation c...

Pumas (Puma concolor; also known as mountain lions and cougars) in southern California live among a burgeoning human population of roughly 20 million people. Yet little is known of the consequences of attendant habitat loss and fragmentation, and human-caused puma mortality to puma population viability and genetic diversity. We examined genetic status of pumas in coastal mountains within the Pe...

The driving mechanism that is responsible for the uplift of intracontinental mountains has puzzled geologists for decades. This study addresses this issue by using receiver function images across the Chinese Tianshan Mountains and available data from both deep seismic profiles and surface structural deformation. The near-surface structural deformation shows that the Tianshan crust experienced s...

Several properties within the eastern Eyre Mountains are currently undergoing tenure revue. This report provides geological information relevant to these reviews, particularly on the sequence of glacial deposits south from Kingston. The geology of the Eyre Mountains is dominated by low-grade metasedimentary rocks of the Permian Caples terrane, becoming increasingly schistose toward the northeas...
