Water chemistry and its ecological implications have been extensively investigated in temperate high-mountain lakes because of their role as sentinels global change. However, few studies considered the drivers water tropical mountain underlain by volcanic bedrock. A survey 165 páramo Cajas Massif Southern Ecuador Andes identified 4 independent chemical variation gradients, primarily characteriz...
ABSTRACT The structural complexity of active faults and the stress release history along fault system may exert control on locus extent individual earthquake ruptures. Fault bends, in particular, are often invoked as a possible mechanism for terminating However, there few records available to examine how these factors influence along-fault recurrence earthquakes. We present new paleoearthquake ...
We studied the effect of solar radiation on the incorporation of [(sup3)H]thymidine ([(sup3)H]TdR) and [(sup14)C]leucine ([(sup14)C]Leu) by bacterioplankton in a high mountain lake and the northern Adriatic Sea. After short-term exposure (3 to 4 h) of natural bacterial assemblages to sunlight just beneath the surface, the rates of incorporation of [(sup3)H]TdR and [(sup14)C]Leu were reduced at ...
There is little information about moisture changes in different altitudinal belts mountainous regions of the southern Russian Far East. We present ecological and taxonomic compositions diatom flora identify botanical composition peat small mountain lake/mire complexes located Central Sikhote-Alin Mountains, within large landslides on paleovolcanic slopes. Frequent assemblages peat-forming plant...
The AguelmamAzegza lake is located in the Middle Atlas mountain range, this region consists of carbonate rocks Lias. It best-watered and richest Morocco terms wetlands, especially natural lakes, rivers fresh springs. lake’s water supply ensured by inflows form underwater sources fed precipitation (rain snow) following tectonics genesis karstic formations dissolution rocks. declining trend level...
A biological study was conducted to find out about reproduction and feeding of G. lacustris in Neur Lake from northwest mountains of Iran. Plankton diversity, hydro-chemical factors and substrate characteristic were recorded monthly. Findings showed that reproduction period of this species was short and limited to May and the mean brood size was 10.2 ± 5.3 eggs per female. The hydro-chemical an...
Lake Oroville is a large artificial lake created by the construction of a 235-mhigh earth dam on the Feather River, California, near the city of Oroville. Its storage capacity is about 4.4 × 109 m 3, and its maximum depth is about 200 m. There was no significant increase in seismic activity in the lake region following impoundment of the dam late in 1967 until the occurrence of many small seism...
Abstract. There have been rapid increases in both the number and expansion of proglacial lakes across High Mountain Asia. However, relationship between glacier dynamics remains unclear Himalayan region. Here we present surface elevation, flow-velocity changes, lake Thorthormi Lugge glaciers Lunana region, Bhutanese Himalaya, during 2000–2018 period using photogrammetry GPS survey data. The lowe...
