This comparatively new type of statistics is a powerful alternative to traditional null hypothesis tests . Global amphibian decline . Here, the focus of my own work is on the demography and dynamics of amphibian populations. I have a strong interest in research in the field of conservation biology, especially if the results of a research project can actually be used to solve conservation problems in the real world. Most research in conservation biology may lead to important insights but a link to management and policy is hard to establish.
Inducible defenses represent a particularly intriguing form of adaptive phenotypic plasticity.
The cue that activates the inducible defense can often be manipulated independently from other aspects of the environment, which provides an opportunity to measure the costs and benefits of the defense in the absence and presence of enemies. Many such measurements have been made, with mixed success. One reason that supposedly defensive structures may contribute no measurable benefit is that they are in fact not adaptive for escaping enemies, but have evolved instead in response to other aspects of the environment that correlate with the presence of predators.
