Effects of birds on the intensity of ant rain: a terrestrial form of invertebrate drift

Article Abstract:

A small percentage of wood ants crawl up trees to gather food and return to the ground by free-falling. A field experiment was conducted to test the hypothesis that 'ant rain' increases in the presence of birds. The findings lend support to the hypothesis. The percentage of ants falling from trees where birds came to forage ranged from 2.9% to 28.4%, while the percentage of falling ants in trees without birds dropped to a mean of 3.7%.

Substratum - mediated heart rate responses of an invertebrate to predation threat

Article Abstract:

Heart rate of invertebrates when exposed to predator and nonpredator threat is presented. Impact of the physical environment in such a situation is discussed. Aequipecten opercularis, a juvenile queen scallop, and Asterias rubens, a common starfish is used as proxies for the experiment.

Subtidal food thieves: interactions of four invertebrate kleptoparasites with the sea star Leptasterias polaris

Article Abstract:

Interactions of kleptoparasites with Leptasterias polaris, or sea stars, have been studied. This sea star is able to obtain large buried clams, and other carnivores cannot do so, so the sea star may make a key contribution to the diet of kleptoparasites.
