| Abstract: | Seeds of Mockernut Hickory represent a changing environmental resource in time and space to two species of snout beetles who partition the common food resource along a spatial and temporal gradient. Conotrachelus affinis, a generalized predator with short snout, utilizes early spring nuts with thin husk, unhardened shell, and little or no kernel in the endosperm. This beetle, a typical r-selected species, has a fast growth rate, short larval period (life cycle completed in 3 months) and emerges before shell... |
