Talk:Minimum viable population

This page was a mess, so I made some grammatical corrections and elaborated a bit more. However, my biology knowledge is limited. It's not my field. Could someone possibly put in a real life example, and give a couple different PVA models? --aciel 02:28, 12 December 2005 (UTC)
Distinct or Extinct?
- Two groups of house cats in separate houses which are not allowed outdoors are also technically distinct populations.
Wait- they surely are technically distinct - but was this intended to say technically extinct? - Eric 18:40, 24 December 2006 (UTC)
A little more grammar needing tidying up.
"There are a marked trend for insularity, surviving genetic bottlenecks and r-strategy to allow far lower MVPs than average." Should be perhaps "There is a..." or something like "There are species with a...", perhaps. Not sure what is wanted to be said. For the consideration of any future editor who feels confident enough to make the necessary changes, on their own recognisance... 18.104.22.168 (talk) 23:55, 17 January 2008 (UTC)
- There surely is one. What it is is unknown (at least to me). Note that by the definition, it isn't actually the smallest survivable population, but the smallest with a 90-95% chance of survival -- so populations smaller than the MVP can actually survive. Thus, though populations as small as 20 humans have survived, though with deleterious genetic effects (See Pingelap - widespread color blindness), that doesn't necessarily mean the MVP is that small.
- It should be fairly low, since we have survived a major bottleneck in the relatively recent (in evolutionary terms) past (see Toba catastrophe theory).
No, it would be HIGHER now, BECAUSE we survived a major bottleneck, and thus have less total genetic variability. A smaller population with a higher amount of genetic variability would have a greater chance of long-term survival than an equally small population that had previously survived a bottleneck, and thus lacks the needed variability to cope with what it might face. 22.214.171.124 (talk) 17:30, 28 February 2017 (UTC)
