Among mouthbrooding fish, biparental care is rare because the mouth cavity provides a safe brooding site, thus reducing the selective advantages of shared brood care.

Using the novel approach of random slope covariates, we demonstrated that sage-grouse selected for nest and brooding sites closer to conifer removal areas and that the probability of individual nest and brood success declined (β = − 0.10 and β = − 0.74, respectively) as sage-grouse females selected sites farther from conifer removal areas.
Our analyses indicate that this intermediate stage may be used as a model system to interpret the origin of oviposition (brood site) mimicry in Epipactis.
We propose the hypothesis that some deceptive pollination systems evolved directly from earlier (partly) mutualistic systems that maintained the fidelity of the original pollinator(s) even though rewards (nectar/ brood site) were lost.
This criterion is clearly met for pollination mutualisms in which the insects that pollinate plants also depend on them as brood sites (Thompson 1994).
Classic examples of such coevolved brood-site pollination mutualisms are the relationships between figs and agaoinid fig-wasps and between yuccas and Tegiticula moths (Pellmyr et al. 1996; Sakai 2002; Weiblen 2002).
These studies, alongside others dealing with brood-site pollination mutualisms (Pellmyr et al. 1996; Weiblen 2002) and antagonistic (interactions in which one partner is harmed) seed-predation systems (Toju and Sota 2006), confirm that coevolution can be an important driver of phenotypic divergence among populations of strongly interacting species.
Brood-site mimicry is dependent on deceiving female insects seeking an oviposition site.
Epipactis veratrifolia (Orchidaceae) is a model system of aphid mimicry as aphidophagous hoverflies lay eggs on false brood sites on their flowers.
Having come to spend a few days in Rome — for a book festival, the modern author's equivalent of those pilgrimages that set ancient authors travelling from one marvel to the next — I found myself wandering through the nicely cleaned-up archeological site and brooding.
The octopuses may have selected this site for brooding due to its "shimmering seeps", which likely emit warm water that is conducive for the development of the young octopuses the mothers are brooding.
