One of the great joys of science, in my view, is teaching others about science, how it works, and why it is arguably the most advanced type of problem solving ever invented by humans. As graduate students at FIU we are given ample opportunities to pass along our knowledge, expertise, and love of science to the next generation of scientists (undergraduates) through teaching classes, giving public lectures, and directly mentoring individual students. At last count FIU had about 40,000 undergraduates enrolled, so finding motivated students to help out with graduate research is a relatively easy task. After five years in FIU's biology PhD program, I've had the pleasure of mentoring eight students for various lengths of time (six FIU undergrads, one Ursinus College undergrad, and one Miami-Dade high school student). They've assisted me with data entry, data analysis, lab work, literature research, and even field work in the Everglades, including alligator catching. In return, be...

Greetings from St. Paul, Minnesota!  I have left the sweltering heat of south Florida for a few days to attend the American Fisheries Society Conference .  Attending conferences is a must-do for graduate students.  It's a chance to share your research with a large, scientific audience, get feedback from the top scientists in your field, and make connections (and new friends) along the way.  These meetings can be a bit overwhelming so I've generated some tips to help you get through them: Photo Credit . 1)  If you're attending a national meeting, chances are there will be anywhere from 10 to 15 talks going on at once.  Running from room to room to see all of them isn't necessarily the best approach.  Stay in one session for a series of talks and sit near the front.  If there are discussions after the talks, don't run off.  Sit and listen and even participate if you have something worthwhile to add!   Photo Credit . 2) Network network netw...

Good afternoon everyone! I hope everyone had a good summer! For us, school is beginning, once again FIU has become a large traffic jam.  And as I was sitting in my car waiting to leave FIU, I came up with this blog idea. When is accomplishing nothing, more than just accomplishing nothing?                     What I am referring to applies to research with animals.  Often, when you work with some mobile animal, your study organism may not be where you think it is in the environment.  Causing you to spend an entire day in the Everglades searching for your target species, only to go back to your lab empty handed. These events usually precede a very fun conversation with your adviser about what exactly you were doing in the field.                    I found myself in this situation last week, when I spe...

Greetings from the confines of my office!  I have not posted in over a month but lucky for you, the other bloggers have kept you entertained with Alligator vomit , post-quals stress disorder and the joys of working with carcinogens, flammable materials and high-voltage equipment .  If those don't make you want to be a graduate student and/or scientist, then I don't know what will! So what have I been doing?  A whole lot of non-exciting blogging material like processing DIDSON videos , analyzing data, and preparing for conferences.  The good news is now I have some results to share!   One of the most interesting and surprising things I've found in my DIDSON videos is schools of small prey fish (< 12 cm).  Not just one or two on occasion, but nearly every time I go out, in all three of the canals I work in, there are schools.    Some are small (you may need to make the video full screen to even see them): Others are quite large: Some are hi...

Today’s post is the last installment of my series “Grad Student Life Beyond Fieldwork.” Take a look at Part 1 (Classes), Part 2 (Teaching) and Part 3 (Our Offices) to read about other facets of grad student life. Part 4, the post you are reading now, is about the labs where we produce and analyze data. Some measurements we use for our research, like water temperature and salinity, can be measured directly in the field. Other more complicated things like “cyanobacteria community structure” involve taking field samples back to a lab (or multiple labs) for extensive analysis. Below I have posted a “virtual tour” of the lab I work in, the Microbial Ecology Lab at FIU, to give readers an idea of what grad students and scientists do other than walk around wearing lab coats.  Above is the door to the lab. It basically says, “Welcome! You are about to encounter biological materials, carcinogens, flammable materials and high voltage equipment! You should probably turn around.” ...

The first half of this year was a pretty tough time for me. I was preparing to take my qualifying/comprehensive exams, also known as 'Quals'. For the FIU PhD student, these are the exams you must pass in order to become a PhD candidate, which is the point you prove your worthiness/ability to finish and get the okay to continue with your graduate program. At FIU's Biology department, the exams usually consist of 1 day of written responses to questions from each of your committee members (that means 5 straight days of writing) and, about 2 weeks later, a 2-3 hour oral exam with your whole committee. The format can vary based on committee members' preferences or department rules. You receive the official title of PhD candidate once you defend your dissertation proposal, after the exams are over. Several months before the exams, I met with each of my committee members to discuss the topics their questions will focus on, and what materials I should study. Soon enough, I had ...

Florida Bay consists of mud banks so intertwined it takes an experienced boater (or a great GPS chart tracker, if you’re me) to successfully navigate across the bay.   Because flow is somewhat restricted by these mud banks, the basins have developed into unique habitats making each dive of the FCE-LTER seagrass sampling project quite different.   At each of the LTER sites within Florida Bay, we estimate percent cover of all seagrass species and many calcareous green algal species, as well as red, brown, and other green algae.   We monitor water quality over time via nutrient analyses in seagrass and calcareous green algal tissue, and we collect data on salinity, temperature, light penetration, and water turbidity.   Data are located at www.fiu.edu/~seagrass . Sprigger Bank is our monitoring site located at the western border of the bay where salinity is more stable than that of eastern regions.   Sprigger Bank is characterized by dense turtle grass ( Thalassia ...
