BIO 215  Biostatistics

Course Notes:

Biostatistics (Bio 215) is a course intended for students completing the Biological Sciences A.S., A.S. for Transfer to California State Universities or preparing for transfer in a life science area, such as Biology, Evolution & Ecology, Environmental Science, Wildlife Management, Kinesiology, Psychology, and some Nursing and Pharmacy schools.  Some Biology specialty majors, such as Molecular Biology do not require a statistics class, while areas such as Ecology normally do. BIO 215 is also an approved option for the Exercise Science and Wellness A.S. and as preparation for major for a variety of majors such as Geography, Public Health and Sustainability at SDSU. 

BIO 215 is offered both Fall and Spring semesters (one section each). Students successfully completing BIO 215 may be invited to work on research projects with Dr. Ripley.

The Biology Department has updated it's major requirements to accept Math 160 or Psych/Soc/Anth 215 as acceptable options to complete A.S. degrees and the A.S.-T, as of Fall 2019. Please see the Department Chair for a Modification of Major for Spring and Summer 2019 degrees. Students strongly interested in Biology and/or thinking of pursuing graduate school in the sciences are strongly encouraged to take BIO 215 rather than the other options.  

*Transfer update for Spring 2019*:  Grossmont's BIO 215 is now articulated with UCSD's Math 11 and can be used to complete major preparation requirements. You can view this information of UCSD's "Course Transferability Guide" as current Articulation Agreements by Major are not available on Please check with M. Denise Aceves, Articulation Officer or Sarah Moore, Transfer Center Director if you have any questions.


BIO 240  Ecology, Evolution, and Organismal Biology with Laboratory

Course Notes:

Bio 240 is a course intended for students completing the Biology A. S. at Grossmont or preparing to transfer as a Biology major.  Some other majors also require this course, such as Biophysics and Environmental Science, and it also fulfills a requirement for some Pharmacy schools.  

If you are planning to transfer to UCSD, you must take both Bio 230 and Bio 240 at Grossmont and/or Cuyamaca to fulfill their requirement for BILD 1, 2 and 3 as our courses do not split the content up the same way theirs do.  

You should NOT take this course if:

  • you are not preparing to transfer into a major that requires it (it is NOT a good GE choice)
  • you are planning to go into the Nursing, CVTE, Respiratory Therapy, Ortho Tech or Occupational Therapy programs as it is not required
  • you have not had the equivalent of one year of good high school biology, in English
  • you are not SURE you want to be a biology major

In the last two cases, take Bio 120 and see how that goes. Bio 120 is not a prerequisite for Bio 240, but you will do better in Bio 240 with the background that Bio 120 provides and more importantly, if you change your major, it will count for a GE and serves as a prerequisite for the Allied Health programs. 

One section of this course is offered in Fall and in Spring semesters. 


Roly Poly Research Project (RPRP)

The Roly Poly Research Project is an interdisciplinary collaboration among STEM faculty, staff and students where we investigate the population dynamics of our campus wood louse population. There are opportunities to get involved at any level of participation that works for you so contact me by email or stop by to check out what we are working on, or find us on Instagram and Facebook.

*Spring 2020 Update--In person meetings cancelled for the rest of the semester due to coronavirus! 

For Spring 2020, we are meeting on Fridays 12:30-2:30 in 30-128.
