Blog related to climate and environmental research, using R for data an*lysis, data science and for GIS. out my poster presentation on pollen geochemistry of Atlas cedar, and how it can be used to tell us about the climate and environment. If you cant make the conference, or would like to know more details about this work, read on! First, a little background information. Atlas cedar (Cedrus atlantica) is an endemic conifer tree found growing across Morocco in the Rif Mountains, Middle Atlas, and parts of the High Atlas. It is also found in Algeria in the Tell Atlas, and Aures Mountains. Cedar has been in the region for thousands of years, but it is threated by climate change, extreme drought and human activity - particularly logging and Because of the trees longevity, and because it is the only species of Cedrus growing in the region, it is an ideal species to study to learn about the environment and climate of the past. We can be sure that an*lysis of fossil cedar pollen (from lake sediment and peat sediment cores) in the region comes from Atlas cedar. Unlike for example, pine, where the pollen may be from several different pine species (although an*lysis of pine geochemistry can identify pollen to the species level). Cedar is also an early autumn (fall) pollinating species, which means the pollen develops during the summer months, and its geochemistry is in relation to how it is used to tell us about solar UV-B levels. Check out the post This blog post will cover stable isotope an*lysis of Atlas cedar pollen, ongoing work looking at fossil cedar pollen, and describe a method for isolating cedar pollen without using traditional chemical treatments. incoming solar UV-B radiation on the geochemistry of Atlas cedar pollen, focused on the Middle Atlas Mountains in Morocco. The study area was relatively small, with sample sites fairly close together. of daily UV-B radiation.
