in the nighttime, drainage flow occurs along the basin sideslope and advects cold air to the boundary layer over the basin bottom (bbl), intensifying the cooling rate of the layer. a nocturnal cold air lake develops in the basin, attaining a depth nearly equal to the topographical depth of the basin. heat budget analysis of the whole basin surface shows that net radiative flux closely balances ...

Molecular microbial ecology studies have revealed remarkable prokaryotic diversity in extreme hydrothermal marine environments. There are no comparable reports of culture-independent surveys of eukaryotic life in warm, anoxic marine sediments. By using sequence comparisons of PCR-amplified small subunit ribosomal RNAs, we characterized eukaryotic diversity in hydrothermal vent environments of G...

In this study, we estimate life history parameters and abundance for a protected jaguar population using camera-trap data from a 14-year monitoring program (2002-2015) in Belize, Central America. We investigated the dynamics of this jaguar population using 3,075 detection events of 105 individual adult jaguars. Using robust design open population models, we estimated apparent survival and tempo...

There are 22 species of Hamacantha registered from all over the world, and frequently from deep-waters, only two of which had previously been reported from the SW Atlantic. Here we describe a third species for this area, Hamacantha (H.) boomerang sp. nov., collected from deep-sea coral mounds at Campos Basin (off Rio de Janeiro state). We found oxeas 271-630 µm long, diancistras in three size c...

abstract in this research the thermal stratification of the water in the torogh dam basin and the resulted changes in its quality with respect to temperature, salinity and dissolved oxygen was investigated using the dynamic reservoir simulation model. the results indicated that in wet years such as 1998, when the average annual precipitation and the resulted inflows to the basin is higher than ...

this paper tries to systematically survey, with taking theoretical view on geomorphic basin and its changes into account. the purpose of this research is to determine the balance and stability of geomorphic basins from the past to present and then to future. consequently, it tries to determine the balance between energy and input-output materials for example (rainfall , solar radiation, tectoni...
