Awesome, thanks!

User:Sharry99[edit]

I saw your report at WP:AIV. I have created Category:Suspected Wikipedia sockpuppets of Sharry99. ‎ If you are confident of the existence of other socks of this editor that are already blocked, you could add them to the category, per instructions at the top of the page. This is handy for record-keeping, and can form part of the evidence in future sock cases. EdJohnston (talk) 14:20, 8 July 2010 (UTC)

Science lovers wanted![edit]

Science lovers wanted!
Smithsonian logo color.svg
Hi! I'm serving as the wikipedian-in-residence at the Smithsonian Institution Archives until June! One of my goals as resident, is to work with Wikipedians and staff to improve content on Wikipedia about people who have collections held in the Archives - most of these are scientists who held roles within the Smithsonian and/or federal government. I thought you might like to participate since you are interested in the sciences! Sign up to participate here and dive into articles needing expansion and creation on our to-do list. Feel free to make a request for images or materials at the request page, and of course, if you share your successes at the outcomes page you will receive the SIA barnstar! Thanks for your interest, and I look forward to your participation! Sarah (talk) 19:32, 16 April 2012 (UTC)

Your expertise requested about Collodictyon[edit]

Hi this article is really in trouble, but with huge interest in terms of pageviews, apparently a single-celled creature which propels itself (apparently) with four flagella. Wondering if you might point us to better sources. It was in the news recently with a (possibly hyped?) story about how it is one of Earth's oldest living organisms, possibly an ancestor to humans and evolutionary clue, and lived only in a lake in Norway (which we originally thought was Lake As but we think we've got the lake down now via redirect). If you have free time to help we'd be grateful, thanx.--Tomwsulcer (talk) 11:58, 30 April 2012 (UTC)

Sorry to disappoint, but I'm pretty clueless about protozoans. I'd likely be more hinderance than help. HCA (talk) 13:23, 30 April 2012 (UTC)
Thanks anyway. You are most knowledgeable about muscles and such and I thought the flagella might come under your area of expertise. Do you know anybody here at Wikipedia who might help?--Tomwsulcer (talk) 13:35, 30 April 2012 (UTC)

Might need your input here[edit]

I reported an ip for making a BLP, on WP:ANI , he mentions your name as one of two people that have reverted him | Check here for it, it's labeled as "Legal Threat or Now" . Perhaps you can shed more light on it. Looks like it may be Australia's "Snake Man " himself based on his edits

"....We are all Kosh...."  <-Babylon-5-> 17:42, 24 July 2012 (UTC)

Yeah, that's almost assuredly him. He has a reputation for roving the net to both promote his ideas and threaten legal action against those disagreeing with him or criticizing him. He's edited WP many, many times before, mostly either his own WP page (either to sanitize it or engage in promotion) or a few snake taxa he's "published" on (his taxonomy is legendarily awful, to the point that Nature itself identified him by name as an example of why amateur taxonomists are bad for science). His most recent "dispute" (which resulted in vandalism of my talk page a few hours ago) concerns the genus names for the white-lipped and reticulated pythons, which he claims to have re-named (the revisions have not been accepted by any workers in the field). Contrary to his wishes, WP:Amphibians and Reptiles adopted a universal policy of using the (relatively slow and conservative) ITIS database for snake taxonomy, in order to prevent us from having to move pages and redirect links every time a paper is published. While Hoser's antics have certainly not endeared him to me, my reversion of his most recent edits is purely a policy matter. HCA (talk) 18:00, 24 July 2012 (UTC)
Also, I feel compelled to ask "Who are you?"  ;) HCA (talk) 18:03, 24 July 2012 (UTC)

Edit: Convergent evolution[edit]

I don't think you understood my edit here:[1] I didn't add those terms; instead, what I did was move that paragraph from below in order to form a more logical narrative flow. If you believe "Neither term is used correctly", then that paragraph should be deleted. Your reversion here:[2] simply moved it back (and removed link: evolutionary relay). ~Eric F 74.60.29.141 (talk) 08:59, 23 October 2012 (UTC)

Ah, my bad, I guess I didn't look thoroughly enough. Anyhow, I've edited it again to correct the parallel evolution example and remove the "evolutionary relay" bit, since the term seems to be almost never used and apparently means something quite different. HCA (talk) 11:23, 23 October 2012 (UTC)

Thanks for clarifying. ~E 74.60.29.141 (talk) 20:25, 25 October 2012 (UTC)

Wikipedia:Articles for deletion/Tegu[edit]

You deleted this out-of-process some time back. I'm not utterly convinced that it doesn't meet notability requirements, so I'm putting it through AFD. You are of course welcome to comment. Mangoe (talk) 16:33, 7 January 2013 (UTC)

Reptile taxonomy[edit]

I'm somewhat puzzled by this and other reptile reverts where you've used a similar argument (only speaking about the taxonomy; not other things you reverted there). Looking at WP:AAR#Taxonomy, it is clear that a specific source only has been chosen for higher level taxonomy (the infrequently updated and by now highly out-of-date ITIS). At lower levels none has been chosen. That leads to one of the core wikipedia policies, WP:NPOV (e.g., subsections "Good research" and "Balance"). We now have clear evidence that Rhacodactylus sensu lato is problematic, resulting in the validation of Correlophus. Publications presenting comparable evidence for the opposite view (all in Rhacodactylus) are lacking. I note that the lead author of the 2012 paper is Bauer, the top authority on this group, and that the single most complete online database (reptile-database.org) has followed the split too. The recently described C. belepensis would present an additional problem if sticking with one genus. We'd have to disregard it entirely; adding it as the only species of Correlophus would be WP:OR (no one has suggested the genus is monotypic) and adding it as R. belepensis would also be WP:OR (no authority has placed it in Rhacodactylus).
In summary, I'm struggling to find any good argument for keeping the two genera together. While user:Chevyrumble55 certainly should have provided a source when he made the changes, based on your edit summary it appears you were aware of the source, but disregarded it. However, beware that Chevyrumble55 made a spelling mistake: Corellophus instead of the correct Correlophus. If you insist on preserving the outdated taxonomy, please note that Chevyrumble55 removed the two Correlophus (chahoua+ciliatus) from the species list in Rhacodactylus, and modified Diplodactylinae too. I'll leave possible edits dealing with these taxonomic issues to you and other editors. Regards, 212.10.95.175 (talk) 19:30, 18 January 2013 (UTC)

thanks for looking over my shoulder[edit]

I'm no expert on reptiles. I'm trying to improve some of the articles, and it helps to have someone make sure I don't make a bad edit. Please check out my revision. Leadwind (talk) 23:03, 2 March 2013 (UTC)

Thanks for caring about the Burmese Python article[edit]

Thank you for your love of snakes and substantial authorship of the Burmese Python article.

Could you find it in your heart to allow the article to mention that Burmese pythons are snakes that grow quickly to large size, and have proven capable of attacking and seriously injuring or killing infants, children, and adult humans (including experienced snake handlers) as ably detailed by the Humane Society report, Humane Society. "Constrictor Snake Attacks". ?

This factual information will not help sell any snakes, but it is salient to unsophisticated potential snake buyers who rely on Wikipedia for useful information. Its omission leaves the article reading like sales talk for buying one of these wild animals, which the article describes as attractive and popular.

The HSUS is an advocacy group, one that has the explicit goal of ending all exotic pet ownership, from Burmese pythons to betta fish. Extremist animal-rights organizations like the HSUS are not a reliable source, and cannot be used on WP.
Furthermore, the excessive focus on their dangers is out of place - WP is not here as a pet guide, either for or against any species. You don't see any such notes on the pages for wolves or ocelots or sharks, so it doesn't belong with Burmese pythons. HCA (talk) 19:05, 7 July 2013 (UTC)

To underscore the rarity of Burmese pythons over 5 metres, might the Wikipedia article mention this 2013 find[edit]

To underscore the rarity of lengths over 5 metres, might Wikipedia's Burmese python article mention this 2013 find, which by subtraction reveals that the previous record in Florida was less than 17 feet long, and thus not much in excess of 5 metres / 16.4 feet, if at all?

... individual specimens over 5 metres (16.4 feet) are rarely encountered.[1] For example, an 18-foot long 128 pound Burmese python found in the wild in Florida in 2013 besting the previous record by more than a foot.[2]
Something like this would be an acceptable addition, yes. Even better would be a source for average or median wild size; the skin trade's records may actually be the best bet for that. HCA (talk) 19:06, 7 July 2013 (UTC)

* Southern limit of the distribution of the green anaconda[edit]

Good evening:

Please allow me to share an article with you. Maybe you will find it interesting:

A barnstar for you![edit]

Original Barnstar Hires.png The Original Barnstar
Thank you very much, I fixed it.

After long search of Matlab codes for the Hill-type muscle model, I failed to find it. So I made it by myself, and I am sharing the codes in my website.

I wish many Biomechanics researchers can take a benefit from them.

Thank you again, and have a nice day~

Cuvier's dwarf caiman[edit]

I didn't know whether Cuvier's dwarf caiman could be called "Cuvier's wedge head caiman" so I consulted Google and found this, which gives wedge head but does not mention Cuvier. However that is not a reliable source and I thought this one much better. It gives common names "Dwarf Caiman, Cuvier’s Caiman, Smooth Fronted Caiman, Musky Caiman" and does not mention "Cuvier's wedge head caiman". The Reptile Database does not mention it either. So I propose to change the sentence to include several vernacular names and think you should provide a reference if you want wedge head to be included. Cwmhiraeth (talk) 05:46, 10 June 2014 (UTC)

So "wedge head caiman" seems to be largely confined to the pet trade (where I'm familiar with it), while in the trade "smooth-fronted caiman" refers to trigonatus. This raises the interesting question: if it's used widely but not in anything that meets the "reliable sources" criteria, should it be included? The problem is that most technical works will simply rely on scientific names (and, indeed, many specialists in the pet trade do too), and less technical RS are extremely uncommon because crocodilian keeping is a rather niche hobby - (there's only one printed book on the topic, AFAIK).

Terrestrial locomotion[edit]

Hello. I would like to open talks about the last revision you reverted. I acknowledge you have been active in the terrestrial locomotion article. But I will appreciate it if you explain the grounds for reverting that edit. Thank you. Mre env (talk) 12:29, 3 July 2014 (UTC)

Because constructal "theory" is fringe at best, useless at worst. No organismal biomechanics researchers ever use it, and the predictions are so vague as to be totally uninformative. HCA (talk) 17:49, 3 July 2014 (UTC)

I am not sure how familiar you are with publications in Constructal Law and Theory. Have you read the paper [3]. On the matter of being called "fringe" it may be a misconception with "new".Mre env (talk) 20:37, 3 July 2014 (UTC)

You mean this non-peer-review paper with no actual experiments, just hand-waving math and a clear ignorance of the basics of biology? Like this sentence "And the force output of the muscles of runners, swimmers and fliers conforms with surprisingly little variation to a value of about 60 newtons per kilogram", which is a) incorrect (muscle force scales with cross-section, not volume), and b) incorrectly assumes that because force per cross-sectional area is constant in vertebrates, it's reflective of a mathematical law, when in reality it can and does vary tremendously (by a factor of more than 10x) in invertebrates and the constancy in vertebrates is likely a developmental constraint (probably lack of paramyosin). The walking section is just as bad - the authors totally ignore elastic energy storage in tendons during walking, a concept which has been around for a good 30+ years at this point, and is known to be a significant factor in cost of transport.
The figure of a bird's CoM during flight is emblematic of the problem - it's a mathematical fiction done to make your calculations easy, as opposed to actually putting real birds in a real wind tunnel and actually measuring the CoM oscillations. That the supposed "calculations" include frequently dropping or approximating terms simply means you can tweak it until you get what you want.
Until the "theory" makes an a-priori prediction with zero data, one that significantly differs from other current theoretical frameworks, and then does an actual experiment, it's not worth talking about. It's all speculation and post-hoc analysis until and unless you can make a falsifiable prediction and test it experimentally. And no, "to within an order of magnitude" is not 'close', it's just plain wrong. If I predict frogs can just 70 feet instead of 7, that's wrong, end of story.
No falsifiable experimental test = not worth discussing. Period. HCA (talk) 20:18, 3 July 2014 (UTC)

Thanks for the input. I am not familiar with the peer-review process of that periodical. At this point, I respect your assessment for Wikipedia.Mre env (talk) 20:37, 3 July 2014 (UTC)
