Typically, an object of interest (such as a preyspecies) is of a different material than the background, and therefore it will affect light differently. It has been suggested that the diet of striped red mullet consists of at least 59 different preyspecies belonging to five major groups. These introduced invertebrates can thus potentially replace the mouse's indigenous preyspecies as nutrient recyclers but probably not without consequences for ecological functioning. Similarly, an array of preyspecies that may be found in the same crop was included. All preyspecies have the capacity to distinguish between predator and nonpredator, for example. However, the frequency of failed drillholes points to preyspecies becoming progressively better adapted. The choice of a preyspecies was guided by several considerations. The preyspecies were attacked in different frequencies (table 1). Spatial associations between generalist predators and a target preyspecies in the field may be interpreted in very different ways. Each group (1-3) received preyspecies in a different order. Similarly, a predator may feed upon a preyspecies that is an important herbivore on one or more plant species. It is also possible that the number of foraging techniques required increases with the number of preyspecies faster in marine than in terrestrial habitats. The mice do not eat the slugs or isopods and the small size of the midge probably disqualifies it from being a significant preyspecies. As the lizard groups received the preyspecies in different orders, order had no influence on the attack rate. Chemoreceptive responses of two sympatric water snakes to extracts of commonly ingested preyspecies: ontogenetic and ecological considerations. Secondary predation is where a predator eats a second predator after the latter has eaten the target preyspecies. Key predators can prevent one or more preyspecies from becoming over-abundant and driving other species to local extinction, especially when they compete for attachment space on rocky substrates. Most obviously, the preyspecies should be reasonably plentiful and not require rapid pursuit, which would be difficult to achieve over soft ground at a reasonable energy cost. Ecological systems typically function under internal and external constraints: preyspecies are checked by predator species; nutrient availability is a function of decay processes; herbivory is limited by antiherbivore toxins.
