| 释义 | monoecious adjective biology specializeduk /mɒnˈiː.ʃəs/ us /mɑːˈniː.ʃəs/ (of a plant or invertebrate animal) having both male and female organs: （植物或无脊椎动物）雌雄同体的 Junipers can be either monoecious or dioecious. 杜松树可以雌雄同株，也可以雌雄异株。 Earthworms are monoecious, meaning that both female and male organs are present within the same worm. Compare dioecious Zucchini are monoecious, which means they have both male and female flowers on the same plant. This species is monoecious and wind-pollinated with slow to moderate growth. Most flatworm species are monoecious, and fertilization is typically internal. These evergreens with needle-like and/or scale-like leaves can be either monoecious or dioecious.

Simulation was undertaken with 100 replicates, using a monoecious population with 100 selected out of either 400 (p=0.25) or 1000 (p=0.1) recorded. This model assumes that the population is subdivided into an infinitely large number of diploid monoecious subpopulations. Monoecious-fig pollinators were common, and species composition and rank abundances were similar between years despite short sampling periods. Because piassava is monoecious, successful pollination depends on the ability of different individual palms to attract insects. A monoecious population mated at random including selfing. A large monoecious population mated at random with one half of all matings being selfing. A monoecious population mated at random excluding selfing. At a finer scale, among monoecious-fig-pollinating genera we found differences in flight behaviour that are consistent with differences in host ecology. In a monoecious fig, wasp larvae and seeds mature together in the same inflorescence. As a result of the low number of captures among dioecious-fig-pollinating species, subsequent analyses are confined to monoecious-fig pollinators. At a finer scale, among genera pollinating monoecious figs we found marked differences in flight behaviour (height and time-of-dispersal). Maize is a monoecious species with male and female reproductive parts that are physically separated, which facilitates outcrossing. Most species are monoecious and a few are dioecious. There were 15.7% dioecious species and 14.2% monoecious ones from all sites. These examples are from corpora and from sources on the web.
