BACKGROUND AND AIMS Molecular evidence indicates that the Neotropical sub-tribe Zygopetalinae is sister to Maxillariinae. Most members of the latter sub-tribe have deceit pollination strategies, but some species produce rewards such as nectar, pseudopollen, resin and wax, and are pollinated by a range of pollinators that include stingless bees (Meliponini), wasps and hummingbirds. By contrast, ...

The lack of cover is one the main accelerators soil degradation. Without protection and exposed to rainfall, breaks particles, causing surface sealing, making infiltration difficult. This study characterizes sealing hydraulic erosion in Ultisols Alto Ipanema Basin. Eight plots were established under treatments: bare with Brachiaria decumbens mulch. Three rain events simulated at 24-hour interva...

The investigation of fires and burning within the archaeological record has a long history, applied methods are diverse. There have been several investigations prehistoric sites, but Middle Bronze Age contexts (2000–1450 BC) Carpathian Basin not widely studied beyond studies ritual or warfare. In this paper, we aimed to add further details topic in household context via thin-section soil microm...

HYPOTHESIS To investigate the intracochlear micromorphology with regard to frequent patterns of cochlear electrode insertion trauma. OBJECTIVE Cochlear implantation is a widely accepted treatment for deafness and high-grade sensorineural hearing loss. Although the device and the implantation methods are continuously optimized, damage of intracochlear structures due to electrode insertion is a...
