Convergent evolution in toothed whale cochleae
Background Odontocetes (toothed whales) are the most species-rich marine mammal lineage. The catalyst for their evolutionary success is echolocation - a form of biological sonar that uses high-frequency sound, produced in the forehead and ultimately ...

Background Differences in morphology, ecology, and behavior through ontogeny can result in opposing selective pressures at different life stages. Most animals, however, transition through two or more distinct phenotypic phases, which is hypothesized to ...

The Deep History of Life [PDF]
The conventional fossil record is built of hard parts—bones, shells, and decay-resistant organic tissues buried in the sediments that accumulate on floodplains, in lakes, and on the seafloor. In the 1950s, geologists first began the routine application of radioactive decay to problems of geologic age.

Legacies in life histories [PDF]
Complex life-histories are common in nature, have many important biological consequences, and are an important focal area for integrative biology. For organisms with complex life-histories, a legacy is something handed down from an ancestor or previous stage, and can be genetic, nutritional/provisional, experiential, as well as the result of random ...

The unpredictably eruptive dynamics of spruce budworm populations in eastern Canada
We examine historical population data for spruce budworm from several locations through the period 1930–1997, and use density‐dependent recruitment curves to test whether the pattern of population growth over time is more consistent with Royama's (1984; Ecological Monographs 54:429–462) linear R(t) model of harmonic oscillation at Green River New ...

Quo Vadis Venomics? A Roadmap to Neglected Venomous Invertebrates
Venomics research is being revolutionized by the increased use of sensitive -omics techniques to identify venom toxins and their transcripts in both well studied and neglected venomous taxa.
