Mid-career burnout in generalist and specialist physicians.

CONTEMPO UPDATES LINKING EVIDENCE AND EXPERIENCE Mid-Career Burnout in Generalist and Specialist Physicians

ASTUDY OF US PHYSICIANS SHOWED that physicians in 1997 were less satisfied in every aspect of their professional life than those asked similar questions in 1986. They were dissatisfied with the time they have with individual patients and their lack of incentives for high-quality care. Similarly, a 1998 study revealed that two thirds of Canadian physicians have a workload they consider too heavy...

Herbivore Preference for Native vs. Exotic Plants: Generalist Herbivores from Multiple Continents Prefer Exotic Plants That Are Evolutionarily Naïve

Enemy release and biotic resistance are competing, but not mutually exclusive, hypotheses addressing the success or failure of non-native plants entering a new region. Enemy release predicts that exotic plants become invasive by escaping their co-adapted herbivores and by being unrecognized or unpalatable to native herbivores that have not been selected to consume them. In contrast, biotic resi...

Coexistence of annual plants: generalist seed predation weakens the storage effect.

We investigate the effect of seed predation on the coexistence of competing annual plants. We demonstrate a role for predation that is opposite to the conventional wisdom that predation promotes coexistence by reducing the intensity of competition. In the common situation where competitive coexistence involves intraspecific competition exceeding interspecific competition, predation can undermin...

Unbiased Transcriptional Comparisons of Generalist and Specialist Herbivores Feeding on Progressively Defenseless Nicotiana attenuata Plants

BACKGROUND Herbivore feeding elicits dramatic increases in defenses, most of which require jasmonate (JA) signaling, and against which specialist herbivores are thought to be better adapted than generalist herbivores. Unbiased transcriptional analyses of how neonate larvae cope with these induced plant defenses are lacking. METHODOLOGY/PRINCIPAL FINDINGS We created cDNA microarrays for Manduc...
