by Luca Marazzi* ‘Who’ is it? Encyonema evergladianum  is a diatom living attached to various substrates, but is also able to move, if it needs to. It was originally described in 1997 by Krammer from samples collected in the Florida Everglades, USA .                   Scalebar = 10 µm     Scalebar = 5 µm   Encyonema evergladianum   (Length range : 16-33 µm; Width Range: 4-6 µm; Striae in 10 µm: 20-22) Where does it live? This beautiful diatom lives in the Everglades periphyton mats,  characteristic multi-color ‘biological carpets’ inhabited by bacteria, fungi and, importantly, by algae attached to soil and plants that feed all sorts of critters. These are in turn eaten by fish that, as we know, become food for birds and for humans too. Nine mile pond .                                            Calcareo...

I know it's been a long time coming, but the Final Four write-up never did get "published" (clicked the wrong button and subsequently became distracted), and the Final Two never got 'writ. This is in large part because the Red Mangrove vs. Periphyton quarterfinal matchup was happening at spatial and temporal scales that exceeded the time limitation of "March." But I also know so many of you have been waiting on tenterhooks for the past six months, so I'm happy to finally report the results of Marsh Madness. (Picture modified. But this was borrowed from Bruce Cochran's book    Marsh Madness: A Lighthearted Look At The Wacky World of Waterfowling . Who knew someone else was wacky enough to base  a series on the idea of "Marsh Madness"?! He apparently  also has   a catchy-sounding book entitled  Revenge of the Trout Zombie: a rollicking river of trout fishing humor .) It looks like after half a year, the mangroves have finally pushed the perip...

Instant replay still While the NCAA final may be over, the long time scale of function in the Everglades means we're just begining the Elite Ate. In the last round , the alligator trumped the spoonbill and the ibis blew away the crocodile. The feral cat continued its siege on the 'Glades, shutting out the once-feared Brazilian pepper.The island apple snail held on against water hyacinth. Floc flopped against sawgrass, the alligator flea forced down the dragonfly, and the mosquito took down the no-see-um. HOWEVER, one match continues in a battle beyond our one-week time scale. Periphyton (3) and Red mangroves (2) remain locked in a vicious tredecuple overtime (i.e. the votes were tied, and I know no one would believe me if periphyton won the coin toss). THEREFORE, this Swamp Sixteen battle rages on, and we need YOUR votes to decide who goes on to face the lean, green, fighting machine of sawgrass. WHO will it be? MORE CAPS FOR THE SAKE OF IT. Periphyton sweaters seem to be creep...

This past week I took my comprehensive exams at Florida International University .  I basically spent five straight days answering questions that my dissertation committee prepared for me.  I experienced a rollercoaster of emotions.  I was excited to show all I have learned and enjoyed the challenging open-ended questions. At the same time it was one of the most difficult things I have ever had to do.  Any ecologist would agree, sitting inside for five straight days is depressing especially when you live in Florida and every day is perfect.  Staying motivated was nearly impossible. I started out strong but by the last day it took every ounce of self control to stay at my computer and finish my last exam.  I knew I was close to the end but the exams wear you down and push you past the edge of your knowledge. I spent six weeks studying for my exams. I started without much strategy, frantically reading every paper that related to my committee's topics.  I...

A bit behind schedule due to "rain delays" in the sawgrass fields of play (i.e. I'm just now getting to it. Not sure if it's actually rained out in the 'Glades the past two days. We'll just assume it has). Anywho, the Round of 32 is done and gone, and with only 2 voters many of these matches came down to a coin toss game of chance. You have your bracket below for SWAMP Sixteen. A review of the matchups: Vertebrates: Alligator 1  vs. Anhinga 9: An easy win for the alligator despite little interaction between the two animals: one basked, one dried its wings. The real  competition was between the two side's cheerleaders: Allie and Anne. Snook 5 vs. Roseate Spoonbill 13: The spoonbill sneaked through using its charisma and mistaken identity as flamingo to its advantage. Green sea turtle 6 vs. American crocodile 3 : I really have nothing to say about this game. Ibis 10 vs. Florida panther 2: Wow! I think the voters/teams mistakened this matchup for UM vs. FIU....

Well! Round 1 is over, and we had some upsets, a couple of blow-outs, and quite a few expected wins. Apparently, primary producers are rather dependable: nothing all that exciting going on in that group. But some things of note elsewhere. Exactly what happened. As few would have denied (except for me. Too much CERP sampling has biased me towards the little man), the alligator trounced the marsh killifish; the panther consumed the woodrat; sawgrass dominated love vine; and the mosquito swarmed the deer fly. The lobate lac scale was absolutely embarrassed by the Mayan cichlid (West Virginia/Kentucky style). BUT we also had some surprise victories: the largemouth bass was fish food for the ibis (some UM fans voting?! And not enough Rehage labbers!), the upside-down jellyfish out-charisma-ed the apple snail, the green iguana mangled the Melaleuca (apparently there's still some bitterness towards Melaleuca out there), and it took a come-from-behind victory for the crocodile to digest th...

I hope all your brackets are ready because it's game time for the Round of 64! If you're running a bit behind and need some input on how to fill out your bracket: basically, just choose whichever organism you think has a greater effect on the Everglades in the head-to-head matchups. Once you determine who wins the first two matches, you'll then choose which organism out of those two teams wins in the next round, etc. You can determine winners based on a cost-benefit analysis that isn't necessarily limited by the two organisms' real-life interactions... or you can be more partial and pick your favorite. After all, it's YOUR votes that matter. I've attached 4 polls to this page, one for each group in the bracket. You'll notice that the organisms are arranged by how they appear in the bracket (i.e. the organism underneath the first is playing the first organism, as it is throughout). You should vote multiple times on the poll (i.e. click multiple boxes): on...
