How do you cite a translation of a text? Do I include the original author followed by the translators, all as authors, and the year of the translation?
For instance what I want to cite is Hennig (1966). But I have and use a translation (from German) of his text. So do I ignore the translators and go with the traditional
Hennig, W. (1966). Phylogenetic Systematics. University of Illinois Press, Urbana. (i've seen this is an article)
or
Hennig, W., D.D. Davis, R. Zangerl (1999). Phylogenetic Systematics. University of Illinois Press, Urbana.

NPR's Krulwich on Science has a podcast on the long lives of lobsters. Its pretty entertaining with a Gilbert & Sullivan song even! It seem like they never age and never die from within (i.e. old age). Or perhaps it is all the Guinness? Interesting research out of Boston University's Marine Program.

Hello there friends of the invertebrates! Over at Deep Sea News, Craig is out for a week so Peter has highjacked the blog and called for Anthozoa Week. Well, we're not going to let him do it all by himself! We'll bringing you news and views from the world of Anthozoa. What is Anthozoan? Glad you asked!
Anthozoa is a class of in the phylum Cnidaria that includes corals and anemones, characterized by no medusa stage (i.e. no jelly) in its life cycle. The word anthozoa means flower (antho-) animal (zoa). So sit back, relax and read an anthology of anthozoa this week here and at Deep Sea News!
What better way to start the week than to head over to Anthozoa.com and learn more about anthozoan biology and research! (Photo above is from Anthozoa.com copyright 2004 by Vreni Häussermann and Günter Försterra)
I'm training him well. First it was fly (although meant for butterfly) and now its octopus. We're working on anemone, but that is pretty advanced.
Castilla et al. (2007) are reporting in a recent PNAS article an interesting property of sea squirt pornography and local oceanography. I know, I'm a frequent purveyor of tunicate smut, but this utter filth may have consequences in the debates surrounding marine reserve design. These authors studied the spawning behavior of intertidal tunicates (Pyura praeputialis, an invasive) from chilean coasts. What they found will make all decent folk turn their insides out. These filthy denizens of the seas let it all out together in a mass orgy. Oh the indecency. Are you sure the children are asleep and not watching over your shoulder? You may want to tuck them in before continuing on.
Sea squirts have mobile "tadpole"-like larvae whose role is typically dispersal since they do not feed. The also don't stay in the water column for too long, preferring to stick their heads to a rock somewhere (figure below shows larval metamorphosis).
A) Mass splooging of P. praeputialis. B) Sperm (SS) and egg (ES) suspensions left dripping in the intertidal. C) 2 meters of foamy splooge. D) Chilean researcher knee-high in sea "squirt" if you know what I mean... Fig. 1 from Castilla et al. (2007).
Joe Paterno, head coach of the Nittany lions at Penn State turns 81 today. Dude, your old. He's still running around like a madman on the field too! I wonder what his secret is?
We used to live near him and when Linda and I would walk our kids on the nearby bike path where he often walked himself, he would stop and smile at our kids. They received Joe PA's blessing. May they grow up to as fit as him at 81!
Not only can your prey give your nourishment and a full belly, it can also be a shield to protect you from predators! A recent article by Jackson & Pollard in the Journal of Zoology described an interesting study in which the ant-snatching assassin bug (Acanthaspis petax) makes a "backpack" of its dead prey to avoid being seen by its predator, the deadly jumping spider (Salticidae)! Masking to avoid predation is not a novel development. There are decorator crabs who will take just about anything and put it on its back (including other live critters), sea urchins will don mussel shells and some weevils will even grow fungi, algae or moss on its back. What I think is cool about this system is the use of "corpse camouflaging". Not only can it save you from starvation, it can save your butt too!
"...they capture prey by grabbing it with their legs, piercing it with their syringelike mouthparts and using the ‘syringe’ to inject digestive enzymes and paralysing saliva. The bug then proceeds to suck up the digested ant tissues from inside the ant’s exoskeleton. Once finished, the assassin bug places what remains of the ant, an empty shell, on its back. The ant carcass adheres because of fine adhesive threads that the bug secretes from its abdomen."-Jackson & Pollard (2007)Now thats recycling! I think we can learn something here. Perhaps we should recycle our food waste into new and life-saving innovations. Hmm... what can we do with all those leftover lemon and orange rinds?
Figure 1 (from Jackson & Pollard (2007)): Two juvenile Acanthaspis petax: one without (left) and one with (right) a mask constructed of ant carcasses."... that the salticid readily detects the masked bug as an object separate from the background, but it fails to identify it as potential prey.[...] As most salticids may be averse to preying on or coming close to ants (Nelson & Jackson, 2006), the fact that the bug’s mask is normally made of ants may be important when the bugs encounter salticids."-Jackson & Pollard (2007)It would be interesting to see how this behavior evolved, what genes turn on this behavior. Once the gene(s) is/are found, how does that gene's phylogeny map over more conservative (i.e. less selected) genetic markers like mitochondrial DNA? A cross comparison with other decorating species would be very interesting in understanding the evolutionary history that gave rise to decorating behavior and how that behavior became instinct that is rooted in the taxon.
So I'm still out of internet service at home (where I do my blogging). I was told by the Verizon employee that helped me when I transferred service to my new address we would have internet access Dec. 12. Well that glorious day came and lo and behold... no internet service. I called that night only to be told by the nice, friendly automatic woman's voice (after a shouting a series of yes and no's, account numbers, etc.) that she couldn't help me and I need to call back within normal business hours.
So I called the next day and was utterly dumbfounded. Apparently, my account was suspended without my knowledge and the Verizon employee(s) couldn't tell me why. So after being transfered between 6 people (from the US to India at least twice...), hung up on once and shuttled between tech support and sales multiple times I finally came to the conclusion that I needed to start a new account. Fine.
So I got shuttled to a new person who quoted me the lowest price of $21.99. My old service was $14.99! In order to get that rate I had to order service online. OK, but I don't have internet service... His advice was to go to a buddy's. Fortunately for me I still do occasionally go into work and can obviously access the internet there or at the cafes where I sometimes operate out of (or the bar like I am right now). Unfortunately for my wife, who has been without internet and email access for 2 weeks now, she stays at and operates from home.
So I ordered service today and assuming it went through like the website said, I should be back in business by Dec. 21st. But, their customer service was horrendous and their answer to difficult questions is to shuttle you to India (whose answer is to shuttle you somewhere else too) or hang up on you. I wasn't being rude, but my tone was probably annoyed after about the 3rd person. And to top it off, I can't get the $14.99 rate for DSL without a 2 year committment. Since I know that I will not be here for 2 years and they made no mention of the fees for early termination, I didn't want to take my chances so I went with the 1 year contract at $17.99, still cheaper than ordering over the phone for whatever strange reason.
But don't despair, I'll be back better than ever. My end of the year stress is (mostly) over so I have a bit more time to write. Of course this misadventure has caused me to botch up hosting the Boneyard last week. I sincerely apologize to those who submitted and were expecting the Boneyard to be posted. Brian at Laelaps will be hosting the next edition and I'll make it up when I get fully restored.

It is proper and fitting that the Marine Biological Association of the United Kingdom comes forward with a special volume in its Journal covering these various sponge efforts. Right from the start of the Association, way back in 1884, and up to the present, the Journal has published sponge papers on a regular basis. Sponge fisheries and sponge culture were subjects addressed repeatedly in the earlier volumes of the Journal by E. Allen, the first secretary of the Association (1896), G.P. Bidder (1896, 1902) and L.R. Crawshay (1915, 1939). Sponge epigones such as A. Dendy and M. Burton discussed taxonomy, faunistics and ecology in the Journal and contributed to the authorative Plymouth Marine Fauna (e.g. Burton, 1957). Continuing along these lines, the volume presented here unites a series of 43 articles covering a wide range of sponge biodiversity studies, without pretending to delimit past or future eras of sponge research. As such it provides an overview of current sponge biodiversity research at this moment in time, and with 21 nationalities involved demonstrates the strongly international nature of sponge diversity science.And just in case you forgot how cool sponges are and how they are so important, Van Soest opens the whole shebang with:
Sponges are an integral part of marine benthic communities with a high-impact role in benthic–pelagic coupling processes, as an important source of food for demersal grazers and predators, as hosts of a highly diverse microbial biomass, and as bio-eroders. Sponges provide age-old (hygienic) services to humans and continue to be of interest in modern times as sources of an unprecedented array of useful substances.
Though I do use a Mac like any intelligent person does (not to be a wanker Mr. Paddy K), I also run Linux (just switched to the Ubuntu distribution thanks to Mike) running WINE, which can run native windows programs. I haven't tried it out yet, since I've been taking exams, moving and finishing up massive grading, but have heard good things. The stupid thing is the only reason I need a Windows operating system is to run Primer (for my research) and MEGA (for a class). I'm hoping with this open source option I can rid myself of the necessity of using the Windows platform. Though I love my Mac, I would love to be entirely open source, just like how I would like to have research published in open access journals.(CNN) -- True or False: Switching from a Windows-operated computer to a Linux-operated one could slash computer-generated e-waste levels by 50%.
The answer is: TRUE
A UK government study in late 2004 reported that there were substantial green benefits to running a Linux open source operating system (OS) on computers instead of the ubiquitous Windows OS, owned by Microsoft. The main problem with Windows users was that they had to change their computer twice as many times as Linux users, on average, thereby effectively creating twice as much computer-generated e-waste.
The report, titled, "Office of Government Commerce: Open Source Software Trials in Government - Final Report" reported the following:
"There are also potential Green Agenda benefits, through reducing the energy and resources consumed in manufacturing replacement equipment, and reducing landfill requirements and costs arising from disposal of redundant equipment.
"Industry observers quote a typical hardware refresh period for Microsoft Windows systems as 3-4 years; a major UK manufacturing organisation quotes its hardware refresh period for Linux systems as 6-8 years."
The 7th edition the Carnival of the Blue is up at The Natural Patriot. Dr. Duffy has a fantastic collection of wonderful oceanic posts. Be sure to read them all, just like life in the ocean the diversity is tremendous!

Christopher at the Catalogue of Organisms is hosting December's Circus. Get your posts to him BEFORE December 26 as it will be going up a bit early so he (and we all) can enjoy the holidays a bit.
I'm hosting the Boneyard this upcoming Wednesday so lets get those submissions roaring in! Show the world where diversity lies and who is most abundant in the fossil record, I need your help to make this one special. Lets make it the SHELLYARD!! Get those invertebrate fossils posts in ASAP. Oh yeah... (mumbling under breath) i'll take vertocentric posts too i guess...
I've considerably updated the Introduction and Chapter 2 to my dissertation blogging series due to comments from my advisor. It is much improved from before. So feel free to check it out and let me know what you think!
We are also moving this weekend so blogging will be slow. With two kids now, we are cramped in our little ole 2 bedroom duplex that we have called home since we moved to Penn State. Its a great place, but not for a family of 4. We are going to be renting a beautiful home on Mount Nittany, with State Forest for my backyard, a 5 mile scenic commute and plenty of space (in and outside) for our little planulae to run around! Its a beautiful place and worth every penny more than we are currently paying in rent. All hardwood floors, a wood-burning stove, enormous kitchen with oodles of counter space and smart cabinet arrangements, a fire pit in the backyard, a BBQ area with a stove for heat, plus the former owner left us lots of furniture to use. Its almost like heaven, except that we spent all night tonight cleaning it up... Expect pictures once we're settled in.

This week's edition of Nature is chronicling the art of Californian entomologist Steven Kutcher. Kutcher uses the most unorthodox of paint brushes, the insect, to paint brilliant hues with creative strokes.
"Kutcher controls the direction and movement of his arthropods — such as hissing cockroaches (pictured), darkling beetles and grasshoppers — by their response to external lighting.[...] Kutcher's art is more than just a novelty, because it reveals the hidden world of insect footprints. 'When an insect walks on your hand, you may feel the legs move but nothing visible remains, only a sensation,' he says. 'These works of art render the insect tracks and routes visible, producing a visually pleasing piece'. "
My abstract for The Ocean Sciences Meeting was accepted for the Census of Marine Life (CoML) poster session. The meeting is one, if not the, biggest meetings for ocean scientists and I am honored to be a part of the CoML.

My abstract is posted below. If any readers are going to the meeting or in the Orlando area and want to meet up let me know!
Score one for mopping up after corruption! CNN.com reports that the U.S. Fish & Wildlife Service is reversing seven rulings
"that denied endangered species increased protection, after an investigation found the actions were tainted by political pressure from a former senior Interior Department official.Julie MacDonald, the USFWS deputy assistant director at the time, pressured scientists to alter their findings in favor of certain industries that would use the protected land in other ways (i.e. building development). The Union of Concerned Scientists stated that these seven reversals "does not begin to plumb the depths of what's wrong" at the wildlife agency and its implementation of the Endangered Species Act. They have collected 30 cases of direct interference by USFWS over the last 7 years. Including (my favorite) delisting the splittail, a fish found only the California's Central Valley where MacDonald owned an 80 acre farm. Hmm...In a letter to Rep. Nick Rahall, D-West Virginia., the agency acknowledged that the actions had been "inappropriately influenced" and that "revising the seven identified decisions is supported by scientific evidence and the proper legal standards." The reversal affects the protection for species including the white-tailed prairie dog, the Preble's meadow jumping mouse and the Canada lynx."
Also included is critical habitat designation for the only invertebrate considered in these reversals, the stunningly gorgeous Hawai'ian picture-wing fly or Nalo Kihikihi in hawai'ian (Drosophila heteroneura, above from USFWS website). The Center of Biological Diversity reports on the threats for this backboneless beauty:"Seventeen or more species may already be extinct and as many as 50 may be in serious decline. The hammerhead, for example, formerly occurred at 16 sites on four of the island of Hawaii’s five volcanoes. It disappeared from every site and was feared extinct until rediscovered at a single site on the Hualalai volcano in 1993.Hawaii picture-wings have declined because of habitat destruction and the loss of their host plants. Remaining picture-wing species are threatened by degradation of their habitat by feral animals and invasive plants, loss of host plants, predation by introduced yellow jackets and ants, cattle grazing, and fire."

7) Terrestrial molluscs: the perfect models for island biogeography?
Just like Pono the happy face spider, I am as happy as a spider to pass my comprehensive exam and move on with my life. Of course, I was passed with conditions. I have to write 2 reviews in areas my committee felt I needed more background in before my defense: species concepts and how to the community ecology of my system relates to that of other well-studied systems. I agree with them and felt my performance was definitely sub-par, but it what it is and they feel if I correct a few of my deficiencies than I will have no problem finishing my degree. Looks like I'll be helping pay John Wilkins living expenses. All in all they were very supportive and asked good questions that got me thinking about my research in new ways. It was a terrifying, but good, experience.
Dear Committee,
I offer you my head on a block. Please have pity on me and do not take it personally if I break down and cry at any moment during my comprehensive examination tomorrow morning. I beg of you to find it in your heart to find me worthy of donning the title "Dr." and joining the ranks of the academic elite. Remember that you too were one a graduate student. Let us forget the good ole frat boy days of initiation and progress to nurturing and random acts of kindness.
Sincerely, Kevin A. Zelnio

It is with great sadness that the death of Dr. Ken Lee is reported. Born, raised and educated in New Zealand, he was at CSIRO in Australia since 1965. His research has focused on soil ecology and he was an expert biologist of earthworms, mites and enchytraeids. A well written obituary is published in the June issue of Biology and Fertility of Soils (hat tip to the Annelida Listserve). Here are some selected excerpts:
"Over the next 10 years he completed a monographic study of the earthworms of New Zealand, detailing the morphology, systematics and distribution of 178 native and 14 introduced species (The earthworm fauna of New Zealand. NZ DSIR Bulletin 130, 1959). Whilst global knowledge of earthworm taxa and distribution has developed since 1959, the theses advanced in this monograph still form the basis of our understanding of the relations between earthworms and soils. Just one native earthworm species has since been added to the New Zealand fauna!"
"His seminal book on earthworms, whilst highly relevant to his work and of great intellectual standing, was written at home ‘after hours’—an illustration of how his family supported his science."
"Whilst Charles Darwin’s 1881 book The formation of vegetable mould through the action of worms first documented the importance of earthworms and launched soil biology, it was Ken Lee who developed knowledge about earthworms, their ecology and relationship with soils and land use, making masterful contributions to soil zoology and to the understanding of the importance of biological contributions to soil processes on the global twentieth century scene. To quote from the Avant-propos written by Marcel Bouche for the 1985 book Earthworms: their ecology and relationships with soils and land use, “The work of K. E. Lee, which for the first time places earthworms on a world-wide scale in the economy of nature and humanity, takes up again a century later, in modern terms, the message of the great naturalist. By its critical analysis, its synthetic approach and its opening up of all relevant subjects that are accessible to rigorous understanding, this volume of K. E. Lee takes its place as the direct descendant of that of Charles Darwin”."

As you may have heard, a "man-size" fossil sea scorpion was recently found in Germany. Though I focused on the reporting and not the cool science, Deep Sea News confirms that this is definitely a score for the invertebrates. With chelicerae as a big as a toddler, I am pretty sure I would be sliced in half, though I would put up a good fight... Unfortunately, the largest known arthropods are hypothesized to be wiped out large toothy armor-plated fish. So, I am forced to give a point to both parties.
But my friend over at Lunartalks (hat tip to Peter Mc from the Beagle Project) more than makes up for Eurypterids dropping the ball. He reports on Jelly swarms committing genocide at salmon farms off of Ireland and how it makes him really feel.

In preparation for my comprehensive examination next week and because its International Dissertation Writing Month, I will be posting my thesis proposal as I madly try to finish it all in time over the next few days. Feel free to question, correct, nitpick, criticize (constructively, I'm in a fragile state right now!), comment, praise me and make suggestions for improvement. And yes, I'm freakin' out!!!!
"This was a bug you couldn't swat and definitely couldn't step on."How cliché is that? Why is always assumed whenever a 'bug' is mentioned swatting and stepping usually ensue? The following line mentions paleontologists "stumbling" upon the find. As if paleontologists are just out bumbling around without a clue. The author negates himself later in the article by describing how detailed the fossil hunt was, including seeing dark patches in the rock that signaled to them a patch of fossilized organic matter.
"Hundreds of millions of years ago, these sea scorpions had the upper hand over vertebrates -- backboned animals like ourselves."This next quote bothers me, can anyone figure out why? I will send an Aliens of the Deep IMAX movie poster and NOAA Ocean Explorer sticker to a person selected by my excel random number generator from all the correct replies. Contest closes Friday, November 23, at midnight. Email responses to kzelnio:at:gmail:dot:com. The winning response will be published on my blog and I might quote mine other interesting replies at my own discretion. The rules are that I am requiring a minimum 250 to maximum 500 word short answer on why this statement is misleading:
"The research found a type of sea scorpion that was almost half a yard longer than previous estimates and the largest one ever to have evolved."
And we thought we had the upper hand over the arthropods for millions of years. They were just patiently biding their time knowing full well we would destroy ourselves.

In preparation for my comprehensive examination next week and because its International Dissertation Writing Month, I will be posting my thesis proposal as I madly try to finish it all in time over the next few days. Feel free to question, correct, nitpick, criticize (constructively, I'm in a fragile state right now!), comment, praise me and make suggestions for improvement. And yes, I'm freakin' out!!!!
Beetle Systematics
We require a highly motivated Postdoctoral Fellow to assist a
research team to conduct research on systematics of beetles
(Coleoptera), with specific emphasis on the comparative morphology
of beetles. The research will involve research, documentation and
scoring complex matrices of morphological characters and
participation in development of interactive keys to beetle families.
Field work within Australia will be required and extensive use will
be made of electronic data management, imaging and publishing
methodologies. The research will be based at the Australian National
Insect Collection.
The application deadline is 6 December 2007 with interviews in January 2008.
Here is a link to the application form and job description.

A Stable Isotope Bioassay for Seep Primary Production of Particulate Organic MatterOK, a little of the basics. A methane seep is an area where natural gas and oil diffuse from reservoirs below the sediment naturally. The seep I studied is called a brine pool. All you need to know if that a brine pool is weird, like an undersea lake of brine (see picture below). Salt concentrations ~120psu or about 4 times the salinity of seawater. The geologic history is complex, but has to do with a salt diapir from the depths of the sediment that recharges the brine pool. Particulate organic matter (POM) cold be anything with an organic origin but not currently alive; bacteria, dead piece of meat floating down from the surface, fish poop, mussel pseudofaeces, etc. This is filter-feeder food. Though passive predators, such as anemones, can phagocytose (engulf) these particles and take up dissolved inorganic carbon (DIC), this is a minor part of their diet. They are after all predators. I hypothesize that they are eating zooplankton hanging around the seeps. Unfortunately, no one has yet to study the zooplankton at the brine pool, so I do not know they exist there, but past experience shows me that where there is energy there is zooplankton! The zooplankton do feed from the POM pool. Hence passive predators are consumers of the POM indirectly. This is becuase stable isotope trophic fractionation for carbon, sulfur and nitrogen behave in a predictable manner (with some caveats). Meaning, "you are what you eat".
Hydrocarbon seeps provide a rich source of chemical energy in the aphotic, nutrient-poor deep-sea. Yet it is unclear how much chemosynthetic primary production enters the pool of particulate organic matter (POM) that can be utilized by suspension-feeding taxa. To address these questions, tissue stable carbon, nitrogen and sulfur isotope content was analyzed from suspension-feeding taxa at a hydrocarbon seep community dominated by the methanotrophic mussel, Bathymodiolus childressi, in the northern Gulf of Mexico. Two end-member stable isotope mixing models were used to determine the relative input of seep-derived POM to photosynthetic-derived POM that is assimilated into the tissues of the suspension-feeding community. Our results indicate that seeps play an active role in the production of POM, which is assimilated by suspension-feeders. Additionally, we constrain possible sources of nutrients to the POM pool.
