Since the 1970s, the nassariid gastropod Cyclope neritea has been extending its range north along the French Atlantic coasts from the Iberian Peninsula. This may be due to natural spread because of the recent warming of the northeastern Atlantic. However, human-mediated introductions related to shellfish culture may also be a probable explanation for this sudden range expansion. To examine thes...
Kandovan historical village is one of the most important attractive tourist sites on rocky architectures in East Azerbaijan province from the Skirts of Sahand Volcano NW of Iran. This village with unique landscape and rocky historical architecture is on the surfaces of a tuff layer. Nowadays, natural surface weathering of this architecture and intensity of decay phenomena in Kandovan village ro...
Introduction and methods Marine litter density, distribution potential sources, the impact on canyon seafloor habitats were investigated in Motril, Carchuna Calahonda canyons, located along northern margin of Alboran Sea. During ALSSOMAR-S2S oceanographic survey carried out 2019, floor imagery was collected by a Remotely Operated Vehicle 5 km Motril Canyon, 10 3 together with 41 surficial sedim...
Cliff-top boulder deposits (CBDs) are morphological indicators of high-energy conditions. Since 2014, a monitoring CBDs dynamics has been undertaken on the south-western coast Iceland (Reykjanes Peninsula) to monitor their long-term activation (quarrying, transport and deposition) as proxy inter-annual winter storminess variations basaltic cliff erosion processes in context rocky progradation. ...
Karst rocky desertification is a geo-ecological problem in Southwest China because of nature and man-made factors, which restricts the development of local economic and social. Soil and water erosion is one of the most harmful form of rocky desertification, but the management methods still keep in the exploratory stage. Biological soil crust is the organic complexes of biotic components includi...
The involvement of porcupines, Erethizon dorsatum (L.), in the ecology of Colorado tick fever (CTF) virus in Rocky Mountain National Park was investigated from 1975 to 1977. Porcupine dens and feeding activity were found mostly on rocky knolls or on south-facing slopes within open stands of the montane coniferous forest, and 20 adult porcupines were trapped or captured by hand at those location...
Increases in reactive nitrogen deposition are a growing concern in the U.S. Rocky Mountain west. The Rocky Mountain Airborne Nitrogen and Sulfur (RoMANS) study was designed to improve understanding of the species and pathways that contribute to nitrogen deposition in Rocky Mountain National Park (RMNP). During two 5-week field campaigns in spring and summer of 2006, the largest contributor to r...
Rocky planets are thought to comprise compounds of Mg and O as these are among the most abundant elements, but knowledge of their stable phases may be incomplete. MgO is known to be remarkably stable to very high pressure and chemically inert under reduced condition of the Earth's lower mantle. However, in exoplanets oxygen may be a more abundant constituent. Here, using synchrotron x-ray diffr...
Iberus gualtieranus gualtieranus is an arid-dwelling land snail that needs to use karstic fissures as refuge in order to survive in arid environments. Karstic fissures are primarily on vertical rocky walls. Because displacement is costly to terrestrial gastropods, it is predictable that this snail will move on vertical substrates near its refuges. However, this species eats primarily phanerogam...
