Gossypol, a secondary plant compound found in cotton (Gossypium spp.), is known to be toxic to a variety of animals, particularly monogastric mammals and birds. Because ruminants are resistant to gossypol, whole cottonseed and cottonseed meal have been used as a feed supplement for many decades. Concerns over gossypol toxicity arise because of its presence in cottonseed products, particularly livestock and wildlife feed. The concentration of cottonseed in the environment near livestock and wildlife feeding stations presents the possibility that it may be ingested in significant amounts by non-target wild animals, resulting in inadvertent gossypol dosing. A species of significant economic and cultural value is the Northern Bobwhite (Colinus virginianus). However, there are no published data regarding if Northern Bobwhites would consume cottonseed meal given the opportunity. We assessed selection for or against cottonseed meal by performing a dietary preference study. Birds (n =120) were given the choice between commercial game bird feed, scratch grains, and cottonseed meal containing 0.74% total gossypol. We measured feed consumption for five days. The birds’ diet consisted of 51.74% game bird feed, 37.72% scratch grains, and 10.54% cottonseed meal, and percentages varied significantly among all feed types (P≤0.001, n =360). We concluded that Northern Bobwhites selected against the cottonseed meal in favour of the game bird feed first and the scratch grains second. Our results suggest that given the choice, Northern Bobwhites will select against cottonseed meal if other feed choices are available.

The Impact

The impact of nonconsumptive effects (NCEs) in structuring predator–prey interactions and trophic cascades is a prominent area of ecological research. For NCEs to occur, prey need to be able to detect the presence of predators through sensory mechanisms. The investigation of the role of different sensory modalities in predator detection has lagged behind the development of NCE-based theories. This study aimed to determine whether a hierarchy in the reliance upon sensory modalities exists in the rusty crayfish (Orconectes rusticus (Girard, 1852) = Faxonius rusticus (Girard, 1852)) for predator detection and if this hierarchy is altered across different sensory environments (flowing and nonflowing environments). Rusty crayfish were exposed to largemouth bass (Micropterus salmoides (Lacépède, 1802)) odor in either a flowing or nonflowing arena where behavior was recorded under different sensory lesions. Linear mixed models were conducted to determine the impact of lesions, flowing environments, and the interactive effects of lesions and flowing environments on the rusty crayfish ability to respond to predatory stimuli. Results from this study support the significance of sensory multimodality in the rusty crayfish for accurately detecting and assessing predatory threats. Results from this study also suggest a hierarchy in the reliance upon sensory modalities in the rusty crayfish that is dependent upon the environment and the location of rusty crayfish within an environment.
