Sponge Community Structure and Anti-Predator Defenses on Temperate Reefs of the South Atlantic Bight
… interaction between predation and anti-predator defenses of prey is important in shaping community structure in all ecosystems. This study examined the relationship between sponge predation and the distribution of sponge anti-predator defenses on temperate reefs in the South Atlantic Bight. …

Root suckering in Dichrostachys cinerea and a comparison of subspecies africana and nyassana
… are clear. Subspecies africana, with greater structural defenses, survives in areas of high herbivory but is rarely seen under high fire disturbance. The opposite is true for subspecies nyassana, which is poorly defended against herbivory. There was no difference in vegetative propogation by …

Are Chemical Defenses Allocated within Sponges to Defend Regions Most at Risk to Predator Attack?
The allocation of chemical defenses to regions most at risk to predator attack may provide adequate protection at minimal metabolic cost. This study examined chemical defense allocation within three sponge species from a temperate reef by investigating the predictions that: concentrations of …
