Talk:Semelparity and iteroparity

I'm working on expanding this, but I wanted to get an outline and a bit of info up first. Caprette (talk) 01:20, 29 April 2009 (UTC)Reply

semelparity of dasyurid marsupials? edit

The article states that semelparity in mammals is found only in "a few didelphid and dasyurid marsupials." The footnote reference talks only about the first (Brazilian opposum) and not about the latter. The article linked to at dasyurid marsupials makes no reference to semelparity except perhaps this sentence: "Smaller species typically breed at least twice a year, while the larger forms tend to breed just once." It seems to me, though that the "just once" in context means "once a year". Is there a reference for semelparity of dasyurid marsupials? or should it be taken out? --Richardson mcphillips (talk) 19:17, 13 March 2015 (UTC)Reply

r/K selection? edit

If you go the linked article on r/K selection, you read "The theory was popular in the 1970s and 1980s, when it was used as a heuristic device, but lost importance in the early 1990s, when it was criticized by several empirical studies. A life-history paradigm has replaced the r/K selection paradigm ...." Perhaps whoever put the link here, could go the r/K selection article and clarify in the status section why either r/K selection is still valid, or it is still useful to use the phrase "r/K selection" in the context of a "life history paradigm". --Richardson mcphillips (talk) 19:23, 13 March 2015 (UTC)Reply

Missing 'Interesting Trait' edit

The section titled 'Insect Evolution' opens with An interesting trait has evolved in semelparous insects, especially in those that have evolved from parasitic ancestors, like in all subsocial and eusocial aculeate Hymenoptera. This is because larvae are morphologically specialized for development within a host's innards and thus are entirely helpless outside of that environment. This 'interesting trait' is never specifically defined although the following text eventually leads one to think that the trait is 'maternal care'. I think the definition was meant to be inserted between the two sentences I've quoted, making the problem one of omission rather than commission. If I'm correct, however, it's still unclear how the evolution of maternal care developed from parasitism in eusocial insects, as many parasitic wasps, for example, lay their eggs in hosts and immediately leave the scene. Other parasitic wasps, it's true, bring their hosts to a shelter of some sort and guard it. Let me add that this is no way my field so the confusion may well be mine alone.

semelparious Reptile: Labord's chameleon edit

Dear fellow editors, including those most active here; Richardson mcphillips and RobotBoy66. My name is Llydia and I decided to improve the German version of this entry, which is really not meeting any standarts right now. However I also took a close look at the info of the English version and ther's one reptile, that should possibly be added. I would like to invite you to take a look at the candidate: https://en.wikipedia.org/wiki/Labord%27s_chameleon What is your opinion on this? Greetings Llydia (talk) 17:15, 29 March 2021 (UTC)Reply

Sorry about the lengthy delay, Llydia. I missed your note. Labord's chameleon seems like the perfect candidate. Glad the addition was made. RobotBoy66 (talk) 04:36, 15 July 2023 (UTC)Reply
