Coinfecting parasites can modify fluctuating selection dynamics in host–parasite coevolution
Sign Up to like & getrecommendations! Published in 2020 at "Ecology and Evolution"
DOI: 10.1002/ece3.6373
Abstract: Abstract Genetically specific interactions between hosts and parasites can lead to coevolutionary fluctuations in their genotype frequencies over time. Such fluctuating selection dynamics are, however, expected to occur only under specific circumstances (e.g., high fitness… read more here.

DOI: 10.1007/s00265-017-2316-2
Abstract: Although polyandry is common, it is often unclear why females mate with multiple males. While polyandry may provide females with direct or indirect fitness benefits, it can also be costly. Thus, investigating both the costs… read more here.

DOI: 10.1007/s13199-021-00781-5
Abstract: Mutualisms are of fundamental ecological importance, but risk breaking down if one partner stops paying the costs yet still takes the benefits of the interaction. To prevent such cheating, many mutualisms have mechanisms that lower… read more here.

DOI: 10.1021/acs.est.9b05006
Abstract: Acclimation increases tolerance to stress in individuals but is assumed to contribute fitness costs when the stressor is absent, though data supporting this widely held claim are sparse. Therefore, using clonal (i.e., genetically identical) cultures… read more here.
