Introduction: What Are Early Successional Habitats, Why Are They Important, and How Can They Be Sustained?

C.H. Greenberg et al. (eds.), Sustaining Young Forest Communities, Managing Forest Ecosystems 21, DOI 10.1007/978-94-007-1620-9_1, © US Government 2011 Abstract There is a rising concern among natural resource scientists and managers about decline of the many plant and animal species associated with early successional habitats. There is no concise definition of early successional habitats. Howe...

Bayes Factors: What They Are and What They Are Not

Bayes factors have been ooered by Bayesians as alternatives to P-values (or significance probabilities) for testing hypotheses and for quantifying the degree to which observed data support or connict with a hypothesis. Schervish (1996) showed how the interpretation of P-values as measures of support suuers a certain logical aw. In this paper, we show how Bayes factors suuer that same aw. We inv...

Nanorattles or yolk-shell nanoparticles--what are they, how are they made, and what are they good for?

The development of nanotechnology has led to the design of cutting-edge nanomaterials with increasing levels of complexity. Although "traditional" solid, uniform nanoparticles are still the most frequently reported structures, new generations of nanoparticles have been constantly emerging over the last several decades. The outcome of this nano-art extends beyond nanomaterials with alternative c...

Dendritic Spines: What Are They? What Are They For?

machinery is also identified in spines, within specialized subdomains (88, 102). In addition, polyribosomes and protein translational machinery are often anchored at the base of spines (80). Thus increasing evidence suggests that individual spines represent partially autonomous compartments, having their own regulated membrane-trafficking events that shuttle components into and out of the spine...
