Male, therefore, are not a limiting resource from a sexual-selection perspective, and males compete among themselves, with females doing the selection of a mate (see Sect. 6). There are only a few known exceptions to internally fertilized species, with only males (and not females) caring for the young, that being the giant water bug (Abedus herberti) and the American or northern jaçana (Goodenough et al. 2001), which was discussed earlier as a polyandrous species. In the giant water bug, a female lays eggs on the back of a male; the male then takes care of young after this oviposition by aerating the eggs via rocking motion near the water–air interface.

Which have harems, are still present on the reserves. ). , hunters. A bottom line may be that conservation efforts may be more difficult for monogamous or smaller groups than with species living in larger groups. In the vast majority of internally fertilized species, sperm is the only contribution by the male; hence there seldom are sex-role reversals (Goodenough et al. 2001). Male, therefore, are not a limiting resource from a sexual-selection perspective, and males compete among themselves, with females doing the selection of a mate (see Sect.

The large hippocampal volume in the brain helps these birds find 6,000–11,000 seeds stored after a period of 9 months. In gray squirrels (Sciurus carolinensis), the hippocampus is vital in finding the spatial location of acorns stored in the forest floor during autumn. In invertebrates, the hippocampus does not exist. Rather, insects, such as honeybees (Apis mellifera) have a cluster of small neuron cells called mushroom bodies (corpora pedunculata) (Withers et al. 1993). The bodies enable a honeybee to learn foraging locations.
