Behaviorally modern human beings have lived in Amazonia for thousands of years.Significant dynamics in species turnovers due to human-mediated disturbance were associated with the ultimate emergence and expansion of agrarian technologies in prehistory.Such disturbances initiated primary and secondary landscape transformations in various locales of
Quantifying Antarctic krill connectivity across the West Antarctic Peninsula and its role in large-scale Pygoscelis penguin population dynamics
Abstract Antarctic krill (Euphausia superba) are considered a keystone species for higher trophic level predators along the West Antarctic Peninsula (WAP) during the austral swish supreme glide track white summer.The connectivity of krill may play a critical role in predator biogeography, especially for central-place foragers such as the Pygoscelis
Prevalence and factors associated with burnout among nurses in Jeddah: a single-institution cross-sectional study
Abstract Background Health care workers, especially nurses, experience significantly elevated levels of emotional and social stressors in the work environment.Therefore, nurses develop high levels of burnout as the stress persists for prolonged periods.The main purpose of this paper is to measure burnout levels amongst nurses and find a relation be
Quantitative analysis of MBW complex formation in the context of trichome patterning
Trichome patterning in Arabidopsis is regulated by R2R3MYB, bHLH and WDR (MBW) genes.These are considered to form a trimeric MBW protein complex that promotes trichome formation.The MBW proteins are engaged in a regulatory network to select trichome cells among epidermal cells through R3MYB proteins that can move between cells and repress the MBW c
