강좌 소개

Life on Earth appears to be dominated by higher plants and animals. Yet an immense variety of microbial eukaryotes swarm in the foliage, grass, soil, bogs, ponds, streams, lakes, and oceans. These inconspicuous organisms are flagellates, algae, ciliates, sarcodines, slime molds, apicomplexans. This assemblage is generally termed the protists. Our course is to build a comprehensive picture of protistan diversity. The major steps of eukaryotic evolution will be in focus. By tracking phylogenetic affinities in protistan lineages we will elucidate the major branches on the tree of eukaryotic life. Many protists are unicellular. This single cell is simultaneously a self-sufficient organism, which is able to sense, move, feed, and repulse an attack on its own. Therefore, protistan cells often demonstrate greater complexity of organelles, structures, and controls than the specialized cells of metazoan animals and higher plants. We will explore how free-living and parasitic unicells implement locomotion, food acquisition, digestion, osmotic regulation, and how they accomplish their life cycle. We also will look into how protists interact with the environment and manage to be biological success. Within the six modules, we will speak of (1) what protists are, (2) flagellates, (3) sarcodines and slime molds, (4) ciliates, (5) apicomplexans and microsporidians, and (6) finally we will go over the modern phylogeny, will summarize life histories and discuss evolutionary trends in free-living and parasitic protists. This online course will have an optional on-campus extension, when the students have one week of practical exercises in the lab. Using light microscopy, they will observe, explore, and document live specimens and fixed mounts of naked and testate amoebas, foraminiferans, radiolarians, heliozoans, myxomycetes, flagellates, ciliates, gregarines, and coccidians....

Really wanted to take this class -- I love the subject matter and have a Masters in biology -- but the narration is very monotonous in tone. This scientist could greatly benefit from taking a speech and communication course in preparation for teaching! Please switch out the speaker!!

Really interesting course, full of interesting information and fact. Processes described in detail with load of examples given. I really enjoyed this course, its useful for university or just for fun!

Anyone who wants to take this course, prepare to be challenged. Like it's said in the information before you enroll it as an intermediate level course and biology and microbiology knowledge will be assumed. The quizzes are hard and even some questions have mistakes. The links in the supplemntary reading that is provided do not work or are articles which aren't open acces so you have to pay for reading them.

Take this course if you have a background in biology and microbiolgy because otherwise it would be very stressful and frustrating

Es un curso extremadamente completo, brinda conocimientos básicos excelentes, los maestros son muy meticulosos y comprometidos con las respuestas de las dudas. La bibliográfica y material de apoyo que ofrecen los investigadores es de calidad. Lo recomiendo 100% para personas que se encuentren realizando estudios de Paleontología, paleobiología, Geología o Paleobiología.

It was a great course for learning the basics of the phylogenetic tree, the structure and functioning of different protists and their evolution

fascinating course if you want to learn something more about the widely diverse organisms comprised by the tag "protists"

I​'m giving up on this one early. Very little teaching. Expect to do a lot of independent reading.

Not a systematic course
