Consequences of predator-induced defenses in western toads, Bufo boreas. This species generally has three distinct life stages: aquatic larvae, terrestrial juvenile (or eft) and aquatic adult. Evol. Evol. The Eastern Newt (, Il arrive souvent que des caractères de proies soient modifiés en réponse à l’exposition à des prédateurs, un phénomène appelé plasticité phénotypique induite par les prédateurs. 1990. Main Characteristics: Eastern Newts are common North American newts. At birth, they hatch from their eggs in calm, fresh water. The red-spotted newt is the subspecies of the eastern newt found throughout New Hampshire. The red-spotted newt is found from Nova Scotia south to Georgia. Red efts hibernate under logs or rocks in the winter. But whether they also feed on the larvae of eastern newts was unknown. La plasticité morphologique en réponse à des signaux de prédateurs est bien documentée chez les amphibiens; les défenses chimiques induites par les prédateurs ont toutefois reçu assez peu d’attention. In the Spring female newts lay 200-375 eggs by attaching each one individually to aquatic vegetation. Evolution in changing environments. Rarely are they found in fields or open areas far from a forest. Mar. The adult eastern newt eats a wide variety of insects.
