Talk:Nepenthes

message: Nepenthes may catch small vertebrates (I have seen them catch frogs), but I very much doubt ferrets form even an occasional part of their diet! I think this is one of those extraordinary claims that requires extraordinary evidence, or at least a reference of some sort...

message: I'm a little worried about the length of the species list. As it stands, it composes about 2/3 of the article length. People expecting a long read will get three sections down and find that the rest is composed of a single long list and be dissapointed.  Here are some options:
*Move it to a seperate page, as has been done with List of Pinguicula species and List of Drosera species
*Just delete the list and add a link to the Nepenthes classification page, which has a species list, though not in alphabetical order.
*Leave the list on this page but put it into columns to make it more compact
*Delete the list from this page but add the Nepenthes species box templet
Thoughts? --NoahElhardt 05:41, 23 April 2006 (UTC)

replies: text: I just noticed that you added the nepenthes template to the bottom of this page, in all practicality repeating information listed in the article.

thread_title:  Species list 

message: In "Morphology and function":
:Prey usually consists of insects,  but the largest species (N. rajah, N. merrilliana, etc.) may occasionally catch small vertebrates, possibly accidentally.
The phrase "possibly accidentally" seems to me to imply intent on the part of the plant. I think it would make more sense to talk about whether these plants are able to get some benefit from the trapped vertebrates, rather than speculating on what the plant might have intended to catch. I'm going to remove "possibly accidentally", but if anyone has info on what happens to plants after they ingest vertebrates, feel free to add it in. --Eloil 04:21, 9 June 2006 (UTC)
replies: text: Good point! I think the article meant to state that the plants' morphophysiological characteristics indicate that the ideal prey, either by evolution or design, is meant to be insects, but that organisms outside of the "target group" do get caught occasionaly. I'm not sure how to word this better though, and I really don't think its that necessary. I would expect that vertebrates end up being digested, albeit slowly, though I wouldn't be able to cite any sources. --NoahElhardt 04:54, 9 June 2006 (UTC)

message: The article on Nepenthaceae had a decent amount of information on classification that was lost when it was merged with Nepenthes. Do you have any plans to integrate it into this article at some point? BTW, I like the new anatomical diagram! Good work. Maybe another diagram showing digestive zones would add to the article? --NoahElhardt 16:50, 7 October 2006 (UTC)
replies: text: The only information I thought was useful in the Nepenthaceae article concerned the Caryophyllales in general and so that's where I put it. Regards, Mgiganteus1 17:05, 7 October 2006 (UTC)

message: As noted here, giving IPA pronunciations for scientific names can be problematic. If a guide to pronunciation is offered, it should reflect the regional pronunciation where the plant is native. See International Phonetic Alphabet for English for details.  IPA pronunciation has been added for all the currently listed species within the genus Nepenthes; for the most part, these are straightforward, but most of those epithets derived from Bahasa Melayu (Malay) or Bahasa Indonesia adhere to the vowel intonation used by native speakers.

message: Many of the species within the genus have been categorised as hailing from Oceania; I've been through the species pages and re-categorised a number of these to Asia.  While Sulawesi is believed to be in Oceania by some and not by others since it lies east of the Wallace Line, I have not chosen to make this call (indeed, it's probably fair to include species from this region and the island of New Guinea in both).  However, we should not labour under the misapprehension that Sumatra, Borneo or Peninsular Malaysia are part of Oceania.  The Philippines are contested by some, but only for ethnographic reasons, and in this instance I'd like to suggest that we fall back on the Wallace Line definition and keep the Philippines firmly in Asia, since this is how most individuals regard the archipelago.  This way, we have consensus within the genus, at least until any Wiki-wide decision is made.  Attenboroughii (talk) 20:01, 26 November 2007 (UTC)
thread_title:  Geographical categories 

message: On a casual read-through, I thought that this article is well-written and referenced and meets nearly all of the FA criteria. I was wondering if it might be worth a brief collaboration to get it to FA status? I think the main thing missing is a discussion of distribution/habitat and ecology, which would include the infauna (using summary style). Taxonomy/phylogeny is also an easy, short section to produce. Anything else? Wikipedia:WikiProject Plants/Template has some good ideas. Think this is possible? It'd be great to have another FA in the CP project and I think this is the article closest to it among our higher priority articles. Cheers, Rkitko (talk) 03:28, 16 August 2009 (UTC)

replies: text: Working on it now... One thing I did want to ask was the info I removed in the description about the sword-shaped leaf blade really being the petiole. All that I've read doesn't seem to corroborate that. Was that an error or is there a better source? Also, tentative to do list below. --Rkitko (talk) 17:47, 16 August 2009 (UTC)

text: Massive expansion indeed! All I can say is... holy Nepenthes! Since this is your baby, I'll stand by and watch unless you need my help. Summary style is definitely going to be necessary, but I'd try to stick to a minimum number of sections for this article (FAs are meant to be comprehensive and not exhaustive). Acknowledged on the Barthlott reference use. I was using it mostly as a placeholder before I could check elsewhere for the same info. I just like using secondary sources like that since it exemplifies the kind of summary style articles we want to produce for FAs. Let me know if I can be of any help when you're ready to bring your draft "live" :-) Rkitko (talk) 02:01, 17 August 2009 (UTC)
replies: text: No need to wait for me - the sections you've added recently are great! Actually, I think it would be ideal if the main article and daughter articles were written in somewhat different styles - that way they won't be as repetitive. With regards to minimising the number of sections: I agree, and your "Distribution and habitat" section already encompasses at least 3 of mine: Distribution, Environmental conditions, and Habitats. It'll just be a matter of linking the daughter articles at the top of each section. mgiganteus1 (talk) 21:40, 18 August 2009 (UTC)
replies: text: Alright, sounds good. I'm actually better at paraphrasing than I am writing my own material from many sources, so I suppose once you bring the daughter articles live, I can help with the summary style or anything else we need. Oh, and did you see this? Nepenthes bokor and Nepenthes thai were published. If I remember correctly, N. bokor was going to be published by Cheek but Mey got there first with N. bokorensis, so now it's a synonym. I have the pdf if you don't have access and can send it along if you need it. Cheers, Rkitko (talk) 22:38, 19 August 2009 (UTC)

thread_title: To do

message: It says "Some Nepenthes have developed unique, symbiotic relationships with prey, such as N. albomarginata, which almost exclusively traps termites yet produces nearly no nectar. Nepenthes albomarginata gains its name from the ring of white trichomes that are directly beneath the peristome. These trichomes—or "hairs"—are palatable to termites and will attract them to the pitcher. In the course of collecting the edible trichomes, many termites will fall into the pitcher, which is an acceptable loss to the termite colony for the food provided by the plant."
I don't get it: if the amount of food the plant recieves from the termites produces less food in the form of trichomes, than the termites will recieve less food than they lose, and if the amount of food the plant recieves from the termites produces more food in the form of trichomes, than the plant will recieve less food than it loses.  This symbiotic relationship doesn't seem to add up: It's like two snakes constantly eating each others tails and growing bigger and bigger. Evrythn1outof8infity (talk) 06:05, 27 June 2010 (UTC)
replies: text: I'm not sure that the energetics of the relationship have been investigated. But put simply, I think it could be explained by thinking of all the nutrient and energetics inputs for both species involved. The Nepenthes photosynthesizes and also does get some nutrients from the soil. The termites are a population that get their food from many sources and individuals are always being replaced. Since I don't think this is explained in the reference, though, we can't exactly put that into the article. Rkitko (talk) 12:55, 27 June 2010 (UTC)
thread_title:  How does this work? 

message: The first paragraph on the section on symbiosis seems to be incorrect. It states that the termites and the nepenthes have a symbiotic relationship. This didn't make much sense to me since they're eating each other. This can't really be symbiotic since either one or the other is going to come out ahead in terms of energy. I checked the reference, and it doesn't say anything about a symbiotic relationship, nor does it provide any evidence that the relationship is symbiotic. It appears to be a straight predator-prey relationship. (In a symbiotic relationship of mutual consumption if each participant gets a kind of nutrient which is otherwise unavailable. But that doesn't seem to be the case here). Anyway, I deleted the section, but then decided I was being a bit rash and I reverted. Maybe someone else could double-check my criticism and then make the appropriate changes.

message: There is a new story of one bird caught wedged in a pitcher. It is on the bbc website: (link to story) . They do have a photograph. They claim there is precisely one other known case of a bird in one of those pitchers in Germany. Apparently that was in "captivity" too (a cultivar). So the case is not unique. Still, should we wait for a third occurrence, before saying in the article that extremely rarely are able to catch a bird? What do you think? -- Cimon Avaro; on a pogostick.
