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...

Inversion of magnetic data is an important step towards interpretation of the practical data. Smooth inversion is a common technique for the inversion of data. Physical bound constraint can improve the solution to the magnetic inverse problem. However, how to introduce the bound constraint into the inversion procedure is important. Imposing bound constraint makes the magnetic data inversion a n...

In this paper, we studied effect of different parameters including density, viscosity, interfacial tension and solute transfer concentration on phase inversion hold-up. The results showed that change in phase density ratio had no effect on phase inversion hold-up. It also disclosed that the phase viscosity ratio was the most effective parameter affecting phase inversion hold-up and each phase h...

SUMMARY The crustal structure of the Recôncavo–Tucano basin, an aborted rift system that developed in NE Brazil during extension related to opening South Atlantic Ocean, has been investigated through local constraints from receiver functions at 18 seismic stations region. Gravity modelling proved unable unequivocally localize thinning under basin depocentre and, together with a general lack sed...

Abstract. The northern margin of the Ligurian Basin shows notable seismicity at Alpine front, including frequent magnitude 4 events. Seismicity decreases offshore towards centre and Corsica, revealing a diffuse distribution low-magnitude earthquakes. We analyse data amphibious AlpArray seismic network with focus on component, ocean bottom seismometer (OBS) network, consisting 24 broadband OBSs ...

Within the Ukrainian sector of Black Sea, Albian-Cenomanian rift faults formed three large basins, which consisted a system grabens and half-grabens. One sublatitude basins occupied modern Karkinit Trough, Krylov-Zmiiny Uplift, Gubkin Ridge Sulina Depression on Odesa Shelf. The second basin Tetyaev High, Sorokin Marine Continuation Crimean Folds and, apparently, Mountains. third extended from n...
