A recent case is that of whether brightly colored mushrooms are so because of selective pressures leading to aposematic coloration. the issue CAN be answered with fairly simple experiments, but can also be inconclusive, depending on the results. so, it got me curious as to what HAS been studied wrt to this issue, which isn't surprising given that my thesis was in part about investigating aposematic coloration in fishes. so, quick google scholar search turns up potentially relevant articles in 30 seconds, but I don't have access to more than the abstracts. If anyone else is interested in the topic, and has access, might i suggest we look at the following as a start: Why Are Some Mushrooms Poisonous, and Do They Signal Their Unprofitability? Not surprisingly, when you think about common fungivores, there IS evidence to conclude they do indeed signal... but not with visual stimuli.  which, even based on the abstract, leads one to be curious about the genetics of color in fungi, and wonder if color is at all linked to other methods of signalling. btw, olfactory aposematism is not a new concept: http://www.springerlink.com/content/t57126l4p7132203/ might also be worth looking more specifically at the biology of some of the more recognizable "brightly colored" mushrooms like Amanita spp. http://www.journals.cambridge.org/action....=150609 moreover, it might be worthwhile to examine the role of non-commonly thought about fungivores... including other fungi: http://www.journals.cambridge.org/action....d=35519 I am unable to locate a decent treatise on the genetics of the relevant fungi with a quick search, but there is certainly enough here to start with anyway. -------------- "And the sea will grant each man new hope..." -CC

Unfortunately, Am. Nat. is one of the few journals (of ecology) I can't access. However, I have the list of their cited references, and none of them deals with the genetics of coloration in mushroom, nor their selective role. They also clearly state in the abstract that the topic has received little attention. So I suppose most of the work remains to be done. However, this reminds me of fascinating stories about coloration and mimicry in orchids. Stuff that has been deeply studied and explained by adaptive models. Maybe the topic of this thread could shift a little bit. For the lurkers, the origin of batesian and mullerian mimmics (for instance), and the evolution of coloration could be interesting. Not that I want absolutely to go off topic, but what do you think, Thomas, about this project of genetically engineered mosquito in order to fight malaria? I could start a thread about that as it clearly shows that the evolutionary theories could be extremely useful. It also deals with the concept of selfish gene and the units of selection (allele vs. individual), that we've been discussing from time to time. But maybe PT already covered it in great details, I haven't been there for a while.

Ichthyic Posts: 3325 Joined: May 2006 (Permalink) Posted: June 26 2007,16:09    the quick search suggests to me that research regarding the genetics of fungi is apparently a pretty wide open field. considering the implications of fungal chemistry discussed in many biochemistry oriented articles, sounds like a great avenue to take for a student interested in genetics (meaning there is likely some funding available, the subject material is typically easily studied in the lab and in the field, and there is likely budding interest within the larger scientific community). just a quick tangent. -------------- "And the sea will grant each man new hope..." -CC

jeannot Posts: 1201 Joined: Jan. 2006 (Permalink) Posted: June 26 2007,16:30    Regarding color and toxicity... If many edible mushrooms have various flashy colors (which can be the case), having such a color would not be a clear advantage for a poisonous species. And we still don't know whether most fungivores are able to distinguish between colors (I bet slugs are not good at it). We know that pigments are relatively costly to synthesize for an organism. There must be some selective advantage, evolutionary hitch-hiking would not be sufficient to explain their maintenance.

It doesn't, since the signalling has been supported in the very paper he chose to cite, just not with visual cues. but then, I don't give a shit what Martin "thinks", and would prefer the issue being addressed in this thread be the science, and not Vmartin. it's quite possible that coloration in fungi is fitness neutral, or linked to other fitness related traits.  hence the interest in the genetics.   Quote If many edible mushrooms have various flashy colors (which can be the case), having such a color would not be a clear advantage for a poisonous species. Indeed, the other issue not taken into account here, is how potential fungivores view the colorations themselves. Just because they look aposematically colored to US, doesn't mean they appear so to a potential fungivore. John Endler has done some great work of late teasing out the perception bias in this issue. (not with fungi, but with fish) it's a great example of how new technologies allow us to answer questions, as it's only been fairly recently that the ability to directly measure how fish and other animals process visual stimuli has been available. so now, we actually CAN look at how a potential predator views various colors and patterns, and thus make far more relevant conclusions about the role of specific visual cues in signalling. http://www.lifesci.ucsb.edu/eemb....ns.html -------------- "And the sea will grant each man new hope..." -CC

In that case the color could be merely a side-effect. Maybe, but as closely related species have different colors, its seems unlikely that they serve particular physiological purposes. For example, the color of blood (a side effect) is the same in all mammals. And color is often localized on the cap, so it looks like it's there to be seen.

Such force can be innate to living organisms and could represent a force responsible for shapes and coloration of different species. You underestand that such a force have no place in neodarwinism.

I have never agreed that Natural selection is the cause of mushroom's coloration. If I agreed that toxicity of mushrooms is probably detected by wild animal by smell it would not necessary mean that I agree with NS as source of it either. It's only your logic you know. Toxicity of mushrooms is another puzzle. I have mentioned Lethal webcaps. Digestion of this mushroom will destroy your liver - but sometimes first nuissances are detected only after 3 weeks. Anyway the poison will kill the animal that had eaten the mushroom. Obviously such type of poison was not created and maintained by Natural selection. It has no sense - no animal would be able to make relation between mushroom eating and its nuissance after so many days. I have mentioned already Amanita muscaria as very delicious mushroom, Amanita phalloides  as most poisonous one and strangely enough - Amanita muscaria with its toxic effects. Due to its toxic effects the muhroom is sought for by some species (deers) and the others (didelphis) are avoiding it. So to find any darwinistic explanation of such diverse "survival strategy" in the same Genera is very difficult. To find out darwinistic explanation of toxicity of Amanita muscaria is impossible. That's the reason why this thread is dying. Neodarwinists after first research - at least the intelligent among them - see that my point is correct.

I don't see the point. I have never agreed that Natural selection is the cause of mushroom's coloration. If I agreed that toxicity of mushrooms is probably detected by wild animal by smell it would not necessary mean that I agree with NS as source of it either. It's only your logic you know. Toxicity of mushrooms is another puzzle. I have mentioned Lethal webcaps. Digestion of this mushroom will destroy your liver - but sometimes first nuissances are detected only after 3 weeks. Anyway the poison will kill the animal that had eaten the mushroom. Obviously such type of poison was not created and maintained by Natural selection. It has no sense - no animal would be able to make relation between mushroom eating and its nuissance after so many days. I have mentioned already Amanita muscaria as very delicious mushroom, Amanita phalloides  as most poisonous one and strangely enough - Amanita muscaria with its toxic effects. Due to its toxic effects the muhroom is sought for by some species (deers) and the others (didelphis) are avoiding it. So to find any darwinistic explanation of such diverse "survival strategy" in the same Genera is very difficult. To find out darwinistic explanation of toxicity of Amanita muscaria is impossible. That's the reason why this thread is dying. Neodarwinists after first research - at least the intelligent among them - see that my point is correct. Natural and sexual selection as the cause of mushroom's coloration is wrong and misleading explanation (and of toxicity as well). V Let's back up and look at the bigger picture. 1) You cited some research by some real biologists pointing out that toxicity and color are not necessarily related in fungi.  These scientists pointed out this lack of relationship. You have not done any real scientific work here at all, but you are relying on actual scientists to look at actual data and get it published. Why don't you do some actual work, generate your own hypothesis about why some mushrooms are colored, test it, and get it published?  That would be a real contribution. 2) Pointing out how neo-Darwinian mechanisms fail to explain a phenomenon leads you into two corners. In the first place, it does not mean that your explanation is correct or even likely, unless you test that explanation and find evidence that is consistent with it. When hypothesis A fails it does not automatically provide support for hypothesis B. The second problem, if you are arguing that mushrooms were created this way, is that this is a god-of-the-gaps argument. If real scientists can do real experiments and find a natural explanation for the fact that some fungi have colorful fruiting bodies, your god just got a little smaller. 3) Science, unlike religion, does not claim to explain everything. There are lots of places where a real scientist, unlike a creationist, will say "I don't know". Such a statement, and such a situation, does not automatically cause the collapse of a theory which is abundantly supported by lots of other evidence. It also, as pointed out above, does not automatically provide support for alternative explanations; you need to do experiments and generate positive evidence for your explanation before anyone will give it more consideration. And even in that best-case scenario, you still have to generate a BETTER explanation for all of the other facts and evidence that support the rival explanation. There is a lot of evidence for common descent and evolution. Pointing out a single instance where scientists say "I don't know" is not enough to overthrow an explanation which is consistent with millions of other observations. So why don't you give us your explanation of this observation, generate a testable hypothesis, and get busy testing it? Or if that sounds like too much work, why don't you answer the other question - Do you agree with Davison on common descent?

The slightly similar looking Pantherina however, has quite short traditions of being eaten. Not that you would be likely to die if you only ate a little. I might not try it though   Quote 1730: A Swedish Colonel, Filip Johann von Strahlenberg, who spent 12 years in Siberia as a prisoner of war wrote a book titled "An Historico-Geographical Description of the North and Eastern Parts of Europe and Asia" which includes a detailed description of the practice of ingesting tea made from A. muscaria and the practice of drinking the urine of those who have ingested the mushroom in order to recycle the psychoactive ingredients.    "The Russians who trade with them [Koryak - a tribe on the Kamchatka peninsula], carry thither a Kind of Mushrooms, called in the Russian Tongue, Muchumor, which they exchange for Squirils, Fox, Hermin, Sable, and other Furs: Those who are rich among them, lay up large Provisions of these Mushrooms, for the Winter. When they make feast, they pour water upon some of these Mushrooms and boil them. They then drink the Liquor, which intoxicates them; The poorer Sort who cannot afford to lay in a Store of these Mushrooms, post themselves on these occasions, round the huts of the rich and watch the opportunity of the guests comind down to make water. And then hold a wooden bowl to receive the urine which they drink off greedily, as having still some virtue of the mushroom in it and by this way they also get drunk."

Why is that? Molecular markers are not reliable? Well, maybe. This is a sample of what I mean: Quote Integrating molecular and morphological data in the systematics of fungi Parmasto, E. Department of Mycology, Estonian Agricultural University, Tartu, Estonia The use of molecular characters in addition to morphological ones, and the use of cladistic methods has remarkably changed our knowledge on the phylogeny of fungi. A single classification, common for all users, which is based on all available data ought to be coined. Classifications using molecular characters (sequencing data a.o.) are in several cases congruent with the present system (of mainly genera). In other cases, due to the widespread parallelism in changes of morphological character states, the new phylogeny hypotheses are different from the classification in current use. In these cases, the main conclusion drawn from the contradiction of molecular and morphological data is that we have to re-evaluate the usefulness of the characters we used. But there are also cases when cladistic analyses based on molecular and morphological characters are giving extremely different topologies of phylogenetic trees. One of the examples is the system of Hymenochaetales (Basidiomycota, Hymenomycetes): if the tree based on rDNA LSU sequence data is accepted, there are almost no synapomorphic morphological characters supporting the branching pattern. Molecular data taken from the GenBank used for a phylogenetic analysis are in many cases erroneous, mainly due to misidentifications. When only one or some representative species are used to characterize presumably monophyletic genera, the topology of the resulting tree depends on the selection of the species. The number of species included in a study is usually relatively small, causing sampling errors; when additional taxa and species of closely related genera are included, the resulting tree topology is changing. Many studies have been published where no attempts have been made to use combined datasets or to compare molecular data based trees with the morphology-based ones. Studies where changes of morphological characters are mapped on trees obtained using sequence data are surprisingly rare. Shortly: phylogenetic studies of fungi based on molecular characters are extremely fruitful, but we are only halfway in compiling more or less stable classifications. Until that, the modern trend of using rankless taxonomy and denoting clades arbitrarily is causing some chaos. The so-called Linnean hierarchy is nothing more – and nothing less – than a way of showing the phylogenetic relations between species or species groups in an easily understandable way. A system of organisms is a way of communication between all biologists, not only among taxonomists themselves. link (emphasis mine) Now I'm just a user, I don't do any research but when you genetic folks get it all sorted out, I suspect there will still be unhappy people. If morphology doesn't end up being represented in the final product then the product isn't very darn useful for people who are trying to use field guides.

BWE Posts: 1902 Joined: Jan. 2006 (Permalink) Posted: June 28 2007,17:27    Perhaps this makes more sense: Quote Molecular systematic studies of the Agaricales have radically transformed our interpretations of the evolution and classification of gilled mushrooms and their relatives (Hibbett et al. 1997; Moncalvo et al. 2000, 2002; Matheny et al. 2006). The overwhelming majority of species produces fruit bodies with gills (lamellae), but the evolution of gills has arisen numerous times in the Agaricomycetes (Hibbet et al. 1997). Likewise, multiple lineages of “gasteromycetes” (puffballs, bird’s nest fungi, false truffles), species that produce spores in an enclosed fruiting structure, have evolved independently among the Agaricales (Peintner et al. 2001). Studies by Bodensteiner et al. (2004), Larsson et al. (2004), and Binder et al. (2005) have shown that some non-gilled fungi, including reduced or cup-like (cyphelloid) forms and crustose or resupinate forms, share their evolutionary histories with numerous lineages of Agaricales, including some lineages that evolved in aquatic or marine environments (Binder et al. 2001; Hibbett and Binder 2001; Binder et al. 2006). In short, the gross morphology of mushroom fruit bodies is highly plastic and often a poor phylogenetic indicator. These and other studies demonstrated that a broad concept of Agaricales (Singer 1986), including boletes, some polypores, and the genera Russula, Lactarius and their allies, does not form a monophyletic group. Thus, the clade containing predominantly genera and families from the suborder Agaricineae (Singer 1986) was labeled the euagarics clade and represents what we currently regard as the Agaricales (Moncalvo et al. 2002). Most family-level relationships based on morphological characters are artificial, but progress is being made to delimit higher-level monophyletic groups with multiple gene data sets (Matheny 2005; Aime et al. 2005; Hofstetter et al. 2002; Binder et al. 2006). Remarkably, new species and genera continue to be described or placed in the order by molecular phylogenetic analyses. the agarics. Above the agarics isn't much better either but these pages are worth a read. Molecular markers are more accurate for the mycologist who needs a name but for research on growth, chemical properties, ecological issues and etc. or for amateur mushroom enthusiasts, the fact that morphology is rarely related to molecularly derived phylogenetic trees can be a bit frustrating. -------------- Who said that ev'ry wish would be heard and answered When wished on the morning star Somebody thought of that, and someone believed it Look what it's done so far The Daily Wingnut

If morphology doesn't match molecular data, nothing need be done in order to reconcile the two. But convergence (homoplasy) in sequence data, when using basal metabolism genes such as 16S rRNA, being much less likely than convergence in morphological traits, molecular markers are clearly posited as the accurate tool for phylogenetic analysis. The only issue that need to be solved is inaccurate identification. Placing a taxon in the phylogenetic tree is pointless if one cannot identify it in nature without a risk of mistake.

Quote (BWE @ June 29 2007,22:09) But in terms of figuring out the evolution of coloration, it kinda throws a monkey wrench in there doncha think? Well, it depends. Studying the evolution of coloration requires building phylogenies of closely related species (typically within a genus), as this trait seems highly variable. Phylogenies of gene sequences at the genus level usually aren't problematic, they might be if the studied taxa underwent a fast radiation. Otherwise, there is not reason to think that DNA markers should not be reliable. And regarding coloration, this trait should not be mischaracterized during field sampling. However, as in every study regarding the evolution of a highly variable trait, problems may come from incomplete sampling: forgetting species, either because some have not been identified yet, or because the are unavailable, or because several have been misclassified in the same species. The latter could indeed happen in poorly studied organisms such as fungi, were two species may look similar while being more closely related compared to others species showing different colors. But if you want a my personal opinion, I would say that incomplete sampling should not be so problematic. We don't need to know the complete and accurate history of the evolution of coloration, rather a global trend: is it a conserved or a highly variable trait at the genus level? Of course, it may depend on the genus, but a highly variable trait may indicate the action of divergent selection.

It will not determine if coloration has cryptic/aposematic function. It will not explain the function of species coloration at all. It will not solve everything, but as I said, phylogenetic analysis could indicate the action of divergent selection. Of course, it implies that all species of, say, Boletus, share a common ancestor. I hope you don't deny that, Martin. In the end, if we know the genes coding for this trait, fitness experiment can be done (RNA interference, knock-out) to assess the role of coloration. But they certainly won't be necessary. Positive selection could be detected with sequence comparisons, although you may object that mutations may not be random. ??? Anyway, what do you propose, Martin, in order to test your hypothesis (whatever that is)? BTW, such analysis is not needed in butterflies, their coloration is already explained.

I swam near mantra ray in east coast of United states but koan bear I yet have to see. The fruiting bodies the fungi for to have become that way because either accident or benefit. All questions I have answers. You have had to change your first question like this: What specific issue are you questioning? I would make such order of words. Slavonic languages are synthetic languages and it means that subject, verb and object do not have fixed place in the sentence. You can change their position without changing the meaning of the sentence. It is something you cannot do in English/German which are analytical languages - changing position of subject and object will change the meaning of the sentence. "The reverend ridiculed darwinists" has different meaning as "Darwinists ridiculed the reverend". In our language "Duchovny sa vysmieval darwinistom" or "Darwinistom sa vysmieval duchovny" has the same meaning  because of suffix "-om" "darwinist-om". By this suffix I know that the first word in the sentence is an object. We have often hidden subject. You say "He was there" and I say "Bol tam". Because of the hidden subject I can very easily make a mistake like in introductionary sentence. If national socialist darwinist like Arden Chatfield  would start to ridicule synthetic languages as "undedeveloped" he should have to consider that Greek and Latin are syntetic languages too.     Quote The idea she understanding is not. I wouldn't make such a mistake. Obviously you are missing an important point that in Slavonic languages there are some differences between sentences depending on who said them. Woman use different suffixes as man. That's why our languages were called by one prominent linguist as "erotic languages". From the written sentence "I came home tired" I don't know if woman or man wrote it. But I say "Pris-iel som domov unaven-y" (notice also missing subject I - Ja)  and a woman say "Pris-la som domov unaven-a". You see there are two different suffixes. If national darwinist like Arden Chatfield would start to ridicule Slavonic languages as "ancient" ones you should have notice him that according a hypothesis a language using many suffixes prove the contrary that the language is "new".     Quote The fruiting bodies the fungi for to have become that way because either accident or benefit. If you check my grammar I will have no problem with it. To be frankly it would be more instructive as many stupid responses here. Topic: I have questioned the issue of coloration of animals. On some opinion 90% of animal's coloration cannot be explained by natural selection. Because coloration is something everybody sees and coloration play often a major role in recognition, such a view questions natural selection as evolutionary force.

Heh?  I've only read a couple of textbooks on modern evolutionary theory and population genetics, but each of them went into long descriptions of how mimicry and similar false signals do evolve. Suppose there is a bird who has learned to avoid butterflies having a specific pattern.  There is then a selective advantage to looking like the poisonous butterfly.  This has been studied quite a lot. I would hazard to guess that something similar could operate in mushrooms.

A plausible hypothesis is that such animals don't reproduce very well at home because they are adapted to different conditions. Have you heard of "ecological specialization"? Also, adaptation relies on the level of polymorphism in a species. Of course the reasons can differ between different animals. I really don't see how this should be a problem to the ToE. ??? Regarding mushroom. Yeah, there's one article, that failed to link coloration to toxicity. Clearly that means will never find why many mushrooms are colorful. It has to be prescribed evolution... You think you're raising some issue? Well you clearly not. You're merely pointing to something that has not been deeply studied and you fail to provide your own hypothesis. You're boring. Give us something new, some positive evidence for your PEH. Was dog "prescribed", Martin?

Quote The male song is is a low-pitched liquid gurgling, the female’s a mix of chortle calls and downslurred whistles. Martins have a variety of calls, with the most common being a descending cherr. Since Vmartin does insist on yammering, however, it's clear he's not real. And can be as readily ignored as any other annoying, but transient, phantasm.

I really don't see how this should be a problem to the ToE. ??? All species are adapted to different conditions than living close with a man. You suppose that dog's ancestors somehow lived in conditions similar to that of humans. In the same conditions obviously lived ancestors of sheeps and postal pigeons. All the other species lived in different conditions. One would say that ancestors of humans, dogs, sheeps and pigeons lived once in the same forest or what. All the other species lived somewehere on ice-bergs. And that's why other species cannot be domesticated.     I would say that problem of domestication is little bit more complicated that materialistic "they come from different conditions" and "ecological specialisation". Obviously there are some internal factors (genetic variability independent from "conditions")  that enable   some species to be domesticated and the others not.   Quote Regarding mushroom. Yeah, there's one article, that failed to link coloration to toxicity. Clearly that means will never find why many mushrooms are colorful. It has to be prescribed evolution... It is not one article that failed link coloration to toxicity. The fact was known long before any research has been done. Yes, it has to be some non-darwinian force behind coloration of mushrooms.   Quote You think you're raising some issue? Well you clearly not. You're merely pointing to something that has not been deeply studied and you fail to provide your own hypothesis. You're boring. I see. If you cannot explain a phenomenon using standard darwinian explanations  the problem was not deeply studied. I am afraid that if problem was studied more deeply the outcome would be the same. Maybe that's the reason why it is not studied, because it fails to support ToE.   Quote Give us something new, some positive evidence for your PEH. Was dog "prescribed", Martin? There is something in dog's genotype that enables them to be so close to man and what other species do not posses. -------------- I could not answer, but should maintain my ground.- Charles Darwin
