ECOLOGICAL GENERALISM IN DROSOPHILA FALLENI: GENETIC EVIDENCE

Sexual selection and ecological generalism are correlated in antbirds.

Sexual selection is thought to counteract natural selection on the grounds that secondary sexual traits are inherently costly and evolve at the expense of naturally selected traits. It is therefore commonly predicted that increased sexual selection is associated with decreased physiological tolerance or ecological plasticity. Using phylogenetic comparative methods, we test this prediction by ex...

Nematocytes: Discovery and characterization of a novel anculeate hemocyte in Drosophila falleni and Drosophila phalerata

Immune challenges, such as parasitism, can be so pervasive and deleterious that they constitute an existential threat to a species' survival. In response to these ecological pressures, organisms have developed a wide array of novel behavioral, cellular, and molecular adaptations. Research into these immune defenses in model systems has resulted in a revolutionary understanding of evolution and ...

Protecting generalism: moving on from evidence-based medicine?

Quality of decision making in modern health care is defined with reference to evidence-based medicine. There are concerns that this approach is insufficient for, and may thus threaten the future of, generalist primary care. We urgently need to extend our account of quality of knowledge use and decision making in order to protect and develop the discipline. Interpretive medicine describes an alt...

Focusing on generalism.

Sexual selection is positively associated with ecological generalism among agamid lizards.

Natural and sexual selection shape the evolution of species but the interplay between them is poorly understood. Two phylogenetic studies on birds have suggested that species with greater sexual dichromatism have a broader habitat use. We show that in agamid lizards, species with more elaborate secondary sexual traits are also ecologically more opportunistic. Species with greater dimorphism in ...
