Wading Through Research

This guest post was written by James Stroud, Ph. D. student in Dr.  K en Feeley's  lab at Florida International University.  He is a regular blogger on the Feeley lab blog  upwithclimate. ------------------------------------------------------------------------------------------------------------------------- South Florida is a wild place for lizards. And at the moment, as the region’s most abundant native lizard, life sucks for the American green anole Anolis carolinensis . In the recent past a wealth of invasions have occurred from exotic Caribbean Anolis leading to the establishment of up to 10 non-native species around the Miami area, annually creeping further outwards towards the Everglades. The effect of congenerics on American green anoles has been well studied; the presence of an ecologically similar competitor – such as the now widespread Cuban brown anole Anolis sagrei (Fig. 2) – has forced them higher up into the trees and off the g...

This guest post was written by Phil Matich, a graduate researcher in Dr. Mike Heithaus' lab at Florida International University.  _________________________________________________________________________   We just got back from an amazing trip in August!   As always, we left early in the morning and were fortunate enough to catch the tail end of the Perseid meteor shower as we drove to the boat ramp.   On our way to the field site we saw the sun rise over the water and the mangroves, and then got right to work catching sharks.   On the first live, we caught two sharks, 79 and 85 cm total length, and surgically implanted the smaller individual with an acoustic transmitter so that we could track its movements.   Surprisingly, the larger shark was an individual we had caught and tagged in July, and is one of the first sharks we’ve recaptured in the last three years!  

Recently, my colleagues and I named three new Everglades diatom species after much morphological analyses and taxonomic detective work. While the Everglades diatom community may not be as species-rich as lakes in more temperate environments, there are many species waiting to receive a proper name and publication. The reason that so many species continue to be called "species number 17" or "looks like this other species but not quite" is because there just has not been the kind of focused taxonomic research here in subtropical and tropical places in the Western hemisphere. Contrast this to the hundreds of years of research on European diatoms. The Everglades diatom community offers great opportunities for graduate students, like me, to investigate and describe new species!

A few weeks ago, I attended my first national conference, Botanical Society of America’s Botany 2013 Celebrating Diversity! (BSA) in New Orleans, LA. Here are 7 lessons I learned along the way: 1 )       Go to the big conferences, even if you don’t have a lot of data yet I just finished up my first year of my PhD program, and I didn't have a lot of “real” data to speak of. So I did what I could, and presented a poster outlining my doctoral thesis proposal. Unexpectedly, I got so much valuable, constructive feedback from experts in my field.  I really valued this experience, because at this stage in my program, that feedback provided me with new perspectives on my project before I execute it. Plus, I got to know PI’s, post-docs, and graduate students from other universities that expressed interest in collaborating with me in the future. 2 )       Attend the student professional development luncheons, mixers, etc. At BS...

What is algae? This seems like a very simple and easy to answer question. Surprisingly though, many people (even those doing research on specific groups of algae like me), have a tough time answering this question. Mainly, I think this is because we rarely get this question from other people (scientists or laypeople). Also, since science often encourages you to focus your research questions, we rarely have to even think about how a specific group of algae is related to other groups of algae, or how algae fits into the evolutionary scheme of other living organisms (are algae plants or animals?...).

Pine Rockland post-fire Big Pine Key, FL      As I start the first field season of my dissertation research, I am starting to get the sensation that I have jumped onto a sinking ship 1 . My chosen ecological system, the pine rocklands (see photo Big Pine Key), has a laundry list of complex and entangled threats—invasions of plant and insect species, habitat fragmentation, climate change, hurricanes, floods, fire suppression, and of course, since it is only found only within south Florida and Caribbean islands, sea level rise (SLR).               

PhD students at FIU are required to teach a lab for two semesters.  So, for the past two semesters I have been a teaching assistant (TA) for   Ecology lab  and have thoroughly enjoyed the experience.  A typical ecology lab consists of a large majority of pre-professional students (pre -med, -dental, -vet, etc.) who need an upper-level elective.  Translation:  many students are enrolled in Ecology because they have to.  I don't expect my students to change their career paths and become ecologists; I simply want them to understand why ecology is important.   Memorizing terminology and examples, while they have their place, are not as useful in the long-term – it’s the experiences and hands-on activities we remember.    I am an ecologist and all I remember from my undergraduate ecology class is going out to my university’s nature preserve looking at species abundances and distributions.   If a student who is preparing for a career in ...
