A very few studies have been conducted using jujube plants in these regions. Sapkota, et al. [23] reported the best size of jujube suckers (height: 50-100 cm; diameter: 0.36-0.75 cm) in the semi-arid region of New Mexico and suggested the need of more plant-ecological studies.Plant strategies of manipulating predatorprey interactions ...To understand the role of allelochemicals in predator-prey interactions it is not sufficient to study the behavioral responses of predator and prey. One should elucidate the origin of the allelochemicals and be aware that it may be located at another trophic level. These aspects are reviewed for predator-prey interactions in general and illustrated in detail for interactions between predatory ...
