Data repository: Cytotype distributions of the common Dandelion (Taraxacum section Ruderalia) and the Cuckoo flower (Cardamine pratensis) in Europe and how these are affected by climate change
<p>This map contains all datasets and R-scripts used to write the paper with the same name. This map also contains the original research proposal on which the datasets are based. The datasets contain location data on the cytotypes of the common Dandelion and the Cuckoo flower in Europe. The data has been collected using a meta-analysis. The R-scripts present are for data preparation, SDM's for current and future scenarios and bioclimatic variable preparation.</p>
Data from: Isolation by time and habitat and coexistence of distinct host races of the common cuckoo
Isolation by time occurs when different populations of a single species reproduce at different times and thereby reduce the probability of interbreeding, potentially causing divergent adaptation to timing of reproduction, eventually resulting in ecological species separated by timing of reproduction. We analyzed extensive data on timing of reproduction by different host races of the common cuckoo Cuculus canorus that is an obligate brood parasite laying eggs in the nests of many different species of passerine birds. Because different hosts breed at different times, specific host races of cuckoos have adapted to specific hosts by laying eggs when nests of these hosts are available, and such divergence may be further exaggerated by differences in timing of breeding among host races with similar habitat requirements. Host species accounted for a quarter of the variance in timing of breeding by the cuckoo. Common cuckoos reproduced at a similar, but narrower subset of dates as did possible hosts, showing that only a fraction of hosts with specific breeding dates were parasitized. Common cuckoo eggs laid in the 'right' kind of nests, phenotypically matching the eggs of the host, were laid later during the season than cuckoo eggs laid in the 'wrong' kind of nests where the eggs did not mimic those of the host. Pairs of sympatric cuckoo host races differed more in timing of breeding than pairs of allopatric host races, and pairs of cuckoo host races with similar breeding habitat differed more in breeding date than pairs of cuckoo host races with dissimilar habitat, as expected from reproductive character displacement. These findings are consistent with cuckoo host races being isolated by timing of breeding and habitat.
Egg mimicry and host selection by common cuckoos among four sympatric host species breeding within a reed habitat
<p>In the case of cuckoo parasitism, the maintenance of host specificity may be closely related to active host selection. In the reed wetlands of the Yongnian National Wetland Park, China, four host species of common cuckoos<i> </i>(<i>Cuculus canorus</i>) with similar nest structures breed sympatrically, namely, the oriental reed warbler (<i>Acrocephalus orientalis</i>) (ORW), vinous-throated parrotbill (<i>Sinosuthora webbiana</i>) (VP), reed parrotbill (<i>Paradoxornis heudei</i>) (RP) and blunt-winged warbler (<i>Acrocephalus concinens</i>) (BW). Cuckoo parasitism rates on ORW (14.5%) and BW (18.2%) were found to be significantly higher than those on two species of parrotbills (RP 1.4% and VP 0), and cuckoo eggs mimicked the size and coloration of ORW eggs significantly more closely than those of the eggs of the other three hosts. Egg recognition experiments revealed that the ability of ORW and VP to recognize nonmimetic eggs was significantly greater than that of BW and RP. Different life history strategies of the four hosts, including antiparasitic strategy, breeding time period, and population density may partly explain the difference of parasitism in this multiple cuckoo-host system. Our study suggests that determining host life history traits and antiparasitic strategies are important for a better understanding of the specificity of host selection in common cuckoos.</p>
