Abstract Surface meltwater reaching the base of Greenland Ice Sheet transits through drainage networks, modulating flow ice sheet. Dye and gas-tracing studies conducted in western margin sector sheet have directly observed efficiency to evolve seasonally along pathway. However, local evolution systems further inland, where thicknesses exceed 1000 m, remains largely unknown. Here, we infer syste...

ABSTRACT Truncilla macrodon¸ the Texas Fawnsfoot, is currently considered to be restricted Brazos and Colorado river drainages in central Texas, USA. Subfossil specimens resembling T. macrodon from shell middens Trinity drainage have raised questions about its presumptive range. Extant populations occupying are believed donaciformis, but species identity has not been assessed using molecular te...

The current distribution of freshwater fishes across multiple basins along Eastern Brazil can be associated to two main events: river captures or temporary paleoconnections. Apparently, river captures had a more significant role on distribution and structuring of species from upland areas, such as Glandulocauda melanopleura. Populations of this species are found in contiguous drainages in prese...

Analyses of ephemeral granitic drainages of <5 km at South Mountain metamorphic core complex, central Arizona, reveal a previously undocumented process of bedrock strath formation in this setting. Granitic channel banks experience a higher degree of mineral decay than that of granitic channel floors. Electron microscope observations show that grussification along the granitic channel banks occu...

AIM This study aimed to evaluate the benefits of Arnica montana on post-operative blood loss and seroma production in women undergoing unilateral total mastectomy by administering Arnica Montana 1000 Korsakovian dilution (1000 K). MATERIALS AND METHODS From 2012 to 2014, 53 women were randomly assigned to A. montana or placebo and were followed up for 5 days. The main end point was the reduct...

Iranocichla persasp. n. is described from the Shur, Hasanlangi and Minab River drainages flowing into the Persian Gulf at the Strait of Hormuz in southern Iran. It is distinguished from Iranocichla hormuzensis, from the Mehran River drainage, by nuptial males having a bright orange breast and lower part of the head (vs. black), a poorly developed or invisible (vs. distinctive) "Tilapia-mark" in...

Copper mine drainages are restricted environments that have been overlooked as sources of new biocatalysts for bioremediation and organic syntheses. Therefore, this study aimed to determine the enzymatic activities (esterase, epoxide hydrolase and monooxygenase) of 56 heterotrophic bacteria isolated from a neutral copper mine drainage (Sossego Mine, Canaã dos Carajás, Brazil). Hydrolase and mon...
