would an allee effect be stabilising or destabilising to the population over time? if it saturates after a certain population size would have an effect at all?—The preceding unsigned comment was added by 129.31.83.2 (talkcontribs) 19:32 22 June 2006 (UTC)

What about Cicadas?

edit

based on this article: https://www.pnas.org/content/pnas/106/22/8975.full.pdf

Periodical Cicadas' periodicity seems to be connected to the Allee effect, so should it be included in the mechanisms section? It doesn't quite fit any of the proposed mechanisms that are already there. — Preceding unsigned comment added by 167.201.243.113 (talk) 12:58, 24 May 2021 (UTC)Reply

acceleration in the DECREASE of population size?

edit

"although there is acceleration in population size at small densities."

does that mean acceleration in the DECREASE of population size? If so, is there a better way of putting it? Or am I confused about the effect? —Preceding unsigned comment added by 68.123.156.103 (talk) 16:04, 4 October 2007 (UTC)Reply

We're talking about the weak Allee effect here. Most likely it's meant to say that at low densities, the growth rate increases with increasing population size. A strong Allee effect means that this increase causes the population growth rate to turn from negative to positive at some population size. I think with the weak Allee-effect the growth rate is just not negative at low population densities, even when the population is very small.

I tried to make changes to make things clearer, I hope it helps. We probably need a graph to really make things clear.

The three graphs

edit

The caption says that the third graph (the null hypothesis) shows a positive but decreasing proliferation rate for a low population. However, the graph shows that the rate is increasing, not decreasing, until a maximum is reached. Grassynoel (talk) 16:22, 24 April 2023 (UTC)Reply
