Building a "Darterbase" (nee Ulocentra questions)
Posted 06 January 2010 - 01:45 PM
E. baileyi- upper Kentucky, upper Cumberland above the falls, Big South Fork, Rockcastle
E. barrenense- Barren
E. rafinesquei- Green exclusive of range of E. barrenense
E. simoterum- Tennessee and Cumberland
E. bellator- upper Black Warrior
E. brevirostrum- upper Coosa
E. cervus- upper Forked Deer
E. chermocki- upper Turkey Creek (Locust Fork of Black Warrior)
E. colorosum- Gulf Coastal drainages from Perdido to Choctawatchee
E. coosae- upper Coosa
E. duryi- Tennessee from Emory downstream, minus Blue Ridge-draining tribs and most of Duck/Buffalo
E. etnieri- Caney Fork
E. flavum- lower Cumberland, lower Tennessee including Duck/Buffalo
E. lachneri- Tombigbee below and along Fall Line
E. pyrrhogaster- upper Obion
E. ramseyi- Cahaba, Alabama below Fall Line, Mobile/Tensaw
E. raneyi- Yazoo
E. scotti- Etowah
E. tallapoosae- Tallapoosa
E. zonistium- Coastal Plain tribs of lower Tennessee, upper Hatchie; headwaters of Blackwarrior and Tennessee in extreme southwestern Cumberland Plateau
As far as I can figure out, the members of the simoterum group are entirely allopatric from one another, while the members of the duryi group are mainly allopatric except for the lower Tennessee (E. duryi + E. flavum in Highland Rim tribs, E. zonistium in Coastal Plain tribs), upper Duck (E. duryi + E. flavum), upper Coosa (E. brevisostrum + E. coosae), and possibly parts of the Black Warrior (E. bellator + E. chermocki, E. bellator + E. zonistium). The two groups as a whole overlap only in the Tennessee and lower Cumberland drainages.
Any major mistakes or omissions here? I know E. simoterum and E. etnieri have each been split up in the fairly recent past, but I have so far been unable to find the relevant articles. Any links or citations of those would be appreciated!

I'm going to bet that you were thinking of the bluemask darter, part of the stigmaeum complex. If you're interested in that species group too, I have some stuff I can send you off forum that may be of interest.

Urgh...I can't get into the document library. I can't even find it. I remember where it used to be. Is it just me?

Does it show up in your view? Might be something with your permissions. It's only viewed by "NANFA Members" but the files are put there by Support Staff?

Put "blueface" darter in the search. You'll get everything you'd like to know and references in the reference, status and distribution. This will be helpful for your other species (can search on "Etheostoma sp." for the unsubscribed species)

I've been mining Natureserve; with additions from the NANFA checklist and Southeastern Fishes Council list, I have a total of 204 Etheostoma species, including undescribed forms (but not including "ESUs" listed by SFC). I have range information for almost all of them; I am missing E. cf. stigmaeum "Clown Darter" and "Beaded Darter". Searches online have so far been fruitless. Can anyone supply me with the missing info?

What you might want to do is get a hold of Andrea Persons at Southern Mississippi. She's working on at least some aspect this again and is from whence the graphic that's give you this question has come. I'll email you her contact info.

The wide-ranging E. spectabile and stigmaeum, among others, have been chopped up, and caeruleum, nigrum, and olmstedi seem to be ripe for the chopping block. Will the other large-range darters like chlorosomum, exile, blennioides, zonale, flabellare, etc. follow suit? Has variation in any of these been examined recently?
Posted 11 January 2010 - 03:52 PM
And yes. Blennioides is mess. There's at least 3 subspecies that will emerge from the dust (blennioides, philodotum and newmanii). The introgression that Ben and Tom are talking about in the redline darter is probably prevelant in the newmanii subspecies which makes TN an absolute mess, and is probably going to require a basin by basin analysis.
There's currently a fuss between Piller & Bart and Haponski & Stepien going on about greensides... I thought I saw both Kyle and Amanda's papers in the fabled Library of the NANFA Forum (did you figure that out yet?) I also have Pete Berendzen's thesis which I'll email to you.
I think flabellare from the lower TN north is a good species, but there's probably some work to be done on whatever that is in the upper T.
Zonale and caeruleum need some investigation, esp in the TN and Cumb.
I'm glad you're doing this. I wish I had a position somewhere coz I'd sure be served well to have you and the IL boys studying darterology with me

Those of you further along, do you think a project like this would be of merit?
