A cuckoo bird lays its eggs in the nest of a reed warbler. Once hatched, the cuckoo's chicks displace those of the reed warbler, tricking the parent reed warbler into caring for them instead of his own.What kind of ecological interaction does the cuckoo have with the reed warbler?*2 puntosMutualismParasitismCommensalismPredation

Cuckoos are known to lay their eggs in the nests of other (host) birds. The eggs are then adopted and hatched by the host birds. A study by E.B. Chance in 1940 in a paper titled “The Truth About the Cuckoo” demonstrated that cuckoos lay their eggs in the nests of a particular host species.Further, cuckoos appear to mate only within their territory. Therefore, geographical sub-species are developed, each with a dominant foster-parent species, and natural selection has ensured the survival of cuckoos most fitted to lay eggs that would be adopted by a particular foster-parent species. The hypothesis is that the mean length of cuckoo eggs depends upon foster-parent species.Data was available for six different foster-parent species (one of which was the wren). A total of 115 observations were made: for each observation, the length of the cuckoo egg in the foster-parent nest was recorded. Analysis was conducted and the mean length of cuckoo eggs for each foster-parent species was compared.The null hypothesis was rejected (p-value<0.05).Assuming the model assumptions were satisfied we can concludeGroup of answer choicesThere is evidence to suggest that the six population means are equal to each otherThere is evidence to suggest that the six sample means are equal to each otherThere is evidence to suggest that each population mean differs significantly from all other population meansThere is evidence to suggest that each sample mean differs significantly from all other sample meansThere is evidence to suggest that some subset of population means differs significantly from some other subset of population meansThere is evidence to suggest that some subset of sample means differs significantly from some other subset of sample means

The honeyguide bird leads honey badgers to bee hives. The badgers then break open the hives and eat the honey inside. Once the badger is finished, the honey guide birds feed on the leftover beeswax.Which of the following best defines the ecological interaction between the honeyguide bird and the honey badger?Choose 1 answer:Choose 1 answer:(Choice A)   MutualismAMutualism(Choice B)   PredationBPredation(Choice C)   CompetitionCCompetition(Choice D)   CommensalismDCommensalism

Two bird species coexist by feeding on the same type of insects in different parts of a tree. One bird species hunts insects near the top of the tree. The other bird species hunts insects near the base of the tree.
