Patterns of plant species diversity during succession under different disturbance regimes.

abstract：:The tops of intertidal boulders on the east coast of Australia may carry a half-dozen algae, while the undersides may support a dozen or more species of sessile animals; mobile forms such as molluscs, crustaceans, and echinoderms are also common. These organisms are disturbed when boulders are moved by waves or buried...

abstract：:Frugivorous birds disperse the seeds of many fruit-bearing plants, but the fate of seeds after defecation or regurgitation is often unknown. Some rodents gather and scatter hoard seeds, and some of these may be overlooked, germinate, and establish plants. We show that these two disparate modes of seed dispersal are li...

In salt marsh detritus the feeding cues include flavor provided by phenolics such as ferulic acid, pH, salinity, and nitrogen content.
