The lead summarizes the article, but is, I think, too technical and difficult to comprehend. The lead should be as accessible as possible. One problem is that it jumps right into the selection dynamics right after the first sentence. To improve the lead, I would, for example, suggest to add general
251:
Oak trees and powdery mildew are a common host-parasite interaction in nature. I think adding this example would be beneficial to the page. Some research of this interaction has used methods testing a third variable such as altitude which can be described as a method for studying the third variable

Desprez-Loustau, M.; Vitasse, Y.; Delzon, S.; Capdevielle, X.; Marcais, B.; Kremer, A. (January 2010). "Are plant pathogen populations adapted for encounter with their host? A case study of phenological synchrony between oak and an obligate fungal parasite along an altitudinal gradient".

info provided in the "Overview" section to the lead, after its first sentence. Maybe even repeat most of the "Overview" section in the lead. Also, plain-language explanations of central terms in parentheses could help.
326: 491:– aren't both terms describing the same thing, some being more specific than the other? To reduce the count of technical terms in the lead, what do we loose when removing "overdominance caused by"? 252:
effect of coevolution. Due to the varying environment, the response to selection differs, and therefore the phenological changes in the population of both the plants and fungi will differ.c
508:– in the main text, there is only the sub-heading "directional selection". Why do you use the term "selective sweeps" in the lead, then, instead of simply "directional selection"? 944: 635:
Same example. If a specific value of environmental variable favours the parasite - say the mildew likes it damp - then places with values other than that (dry) will be coldspots.
229: 219: 949: 747:– Is "investment" the proper term? It sounds as if evolution would be an active process controlled by the organism, like a human who invests time to get something done. -- 901:
Hmm, there are actually a few papers which indeed use the en-dash, so maybe I am wrong. Please decide what is best, it should only be consistent in the article then. --
331: 939: 359: 444:
Host–parasite coevolution is a special case of coevolution, the reciprocal adaptive genetic change of a host and a parasite through reciprocal selective pressures.
349: 196: 151: 112: 523:
Selective sweeps are one form of directional selection, where the increase in frequency will eventually lead to the fixation of the advantageous allele.
642:
Ideally, this specific example ("the mildew likes it damp") could be added to the article, it would greatly help with understanding this mechanism. --
596:
Yes, but that example is general and doesn't go into the three elements, so it is not really helpful in understanding each of the three elements. --
32: 934: 377: 53: 883:
OK, then it must be changed immediately the GAN process has completed. (The whole thing goes into a tangle if the title changes in mid-stream.)
663:
Between the communities/regions there is a continuous "mixing" of traits by gene flow, random genetic drift, population extinction, or mutation.
865:
instead. The hyphen-minus is also what is used in the article text, except for the first sentence of the lead which has the en dash instead. --
398: 572:
In other words, the specific environmental conditions determine how any genotype of one species influences the fitness of another species.
46: 180: 176: 672:
This is the extinction of populations not species. If population B is lost, populations A and C may meet for the first time and mix.
929: 354: 38: 717:
This result is consistent with the Red Queen hypothesis that sexual reproduction is favoured during host–parasite coevolution
87: 769:. The language of purpose is hard to avoid; the meaning is natural selection. But we don't need the word "investment". 143: 626:
These hotspots are intermixed with so-called coldspots in which only one or neither species adapts to the antagonist.
525:– Isn't that definition different from what was said in the lead ("selective sweeps near an advantageous mutation")? 192: 906: 870: 826: 801: 752: 724: 684: 647: 601: 589:
example is given immediately after the list. I've reworded the start of that paragraph to make its purpose clear.
468: 413: 392: 888: 844: 430: 461:
It is characterized by reciprocal genetic change and thus changes in allele frequencies within populations.
373: 257: 20: 164: 93: 253: 574:– Would be helpful to have, in addition, also an example, as examples greatly help with comprehension. 902: 866: 822: 797: 766: 748: 720: 680: 643: 597: 464: 409: 388: 156: 463:– Why is this specific for host-parasite coevolution, doesn't it apply to coevolution in general? -- 557:– link, or even better use "interactions between species" instead to be more accessible to readers. 168: 160: 857:
Thanks for all the fixes, looking very good now. But one last point: The article title involves a

What environmental conditions could possibly cause a coldspot? 42: 289: 665:– How can extinction possibly lead to mixing of traits? I thought it can only lead to loss. 446:– maybe we can get rid of the first "reciprocal"? Seems repetitive to have this word twice. 191:. If you would like to participate, there are some suggestions on this page (see also 821:
That's it. See a few more comments and replies above, but I would not insist on any. --
