The project aims to assess community invasiveness and the impacts of invasion by Eragrostis plana (love-grass, or Annoni-grass in Brazil) on native grassland in southern Brazil. E. plana is considered the most invasive species of grassland ecosystems in southern Brazil, with about one million hectares of native grasslands invaded. The species was detected in Brazil for the first time in 1957, was spread across the state of Rio Grande do Sul in the 1970s and has been officially considered invasive since 1979. The proposed research involves the integration of knowledge at different levels of biological organization to understand the process of invasion and the possibilities to control it.
The Assistant Curator will participate in the management of the Herbarium, providing professional expertise in plant identification and nomenclature; helping to develop projects that further Herbarium goals of making data available for research and conservations; conducting original research; and taking an active role in outreach for the herbarium for a general audience.
3 year NSF-supported postdoctoral position is available at University of California San Diego, Department of Scripps Institution of Oceanography, La Jolla, CA, USA to study “Evolution of Left-Right Asymmetry in Chordates using Cephalochordates as a Proxy for the Ancestral Chordate.” A major outstanding question is how left/right (LR) asymmetry evolved. Vertebrates are superficially symmetric, but internal organs are asymmetrically arranged across the left/right (LR) axis. This study aims to elucidate the fundamental genetic mechanisms of LR asymmetry in chordates by comparing two distant amphioxus genera (Branchiostoma and Asymmetron). Pharyngeal structures in larvae of both genera are asymmetrically arrayed, but asymmetries differ between them with gill slits opening on the right in B. floridae and ventrally in A. lucayanum. Applicants with a background in evo/devo and/or developmental mechanisms of amphioxus are preferred. A PhD is required.
