Chemically induced defenses in phytoplankton
2009Many organisms, including some phytoplankton and zooplankton, are phenotypically plastic, and respond to predators by changing their shapes – a phenomenon known as “inducible defense.” For example, some rotifers grow large spines in the presence of their predators, and some clones of the common crustacean Daphnia develop protective “neckteeth ...

Predator-Induced Defense in a Marine Bryozoan
Science, 1984Laboratory experiments showed that predation by both trophically specialized and generalized nudibranch species triggers rapid induction of defensive spines in the bryozoan Membranipora membranacea . Spines effectively control the pattern and extent of intracolony mortality caused by nudibranch predation. Previously

Consequences of an inducible defense
2018This dissertation attempts, through four connected experiments, to demonstrate the range of ecological and evolutionary responses to induced anti-predator defenses. The presented works all incorporate the formation of anti-predator colonies by the green alga Chlamydomonas reinhardtii in response to the filter feeding rotifer Brachionus calyciflorus and

Antioxidant Defenses in Metal-Induced Liver Damage
Seminars in Liver Disease, 1996Recent investigations have begun to define more clearly the cellular and molecular roles of oxidant stress in mediating the liver injury and fibrosis of metal storage diseases. Because of a variety of perturbations in antioxidant homeostasis in iron and copper overload, restoring the antioxidant balance to normal, or even exceeding normal levels of ...

Inducible Humoral Immune Defense Responses in Insects
1996There is a revolution taking place in the field of immunobiology that is challenging the widely held dogmatic belief that invertebrates are incapable of mounting true adaptive immune responses when exposed to foreign substances. If the definition of adaptive immunity is predicated on the possession of a thymus or lymph nodes, then invertebrates will ...
