Flow Day!

Mike Bush is a guest blogger and a PhD student in the Trexler aquatic ecology lab at FIU ( http://faculty.fiu.edu/~trexlerj/ ).  -------------------------------------------------------------------------------------------------------------                 Everglades restoration can come in many forms, from ensuring that water heading south through the Everglades Agricultural Area is stripped of excess nutrients before it hits the more natural areas of the Everglades to shuffling around huge amounts of water under Alligator Alley into Fakahatchee Strand. Perhaps no project is as ambitious as the Water Conservation Area 3A Decompartmentalization and Sheetflow Enhancement Project (we just refer to it as “DPM” or “Decomp” for short, thank goodness). DPM is a multifaceted project, with major involvement by the South Florida Water Management District and the US Army Corps of Engineers, that focuses on removing lev...

Why do we still know so little about common species?

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 ground. Fig 1. Ran...

August Shark Sampling

Image
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!   After only a month, the shark has grown 2 cm and gained 1 kg in body mass; the scar fr...

Three new Everglades diatom species named

Image
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!

7 Ways to Make to Most Out of Your First National Conference

Image
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 BSA, there were ...

What is Algae?

Image
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?...).  Anabaena , a common genus of cyanobacteria (aka "blue-green algae"). Previously, I blogged about diatoms that live in periphyton in the Everglades, and what I do to periphyton to remove all the other algae that obscure the diatoms I want to study. So far, I haven't explained what algae is at all, and only explained that diatoms are a special group of algae with cell walls m...
