Insects are one of the most successful classes on Earth, reflected in an enormous species richness and diversity. Arguably, this success is partly due to the high degree to which polyphenism, where one genotype gives rise to more than one phenotype, is exploited by many of its species. In social insects, for instance, larval diet influences the development into distinct castes; and locust polyp...

OBJECTIVES The goal of the analysis was to examine the association between health status and work behavior among men aged 55-69. We specifically examined the conditions under which health is most strongly associated with labor force exit and reentry. METHODS The association between health and labor force transitions was examined using logistic regression analyses, based on data from the 1984 ...

Multiple transitions between care settings in the last phase of life could jeopardize continuity of care and overall end-of-life patient care. Using a mortality follow-back study, we examined the nature and prevalence of transitions between Dutch care settings in the last 3 months of life, and identified potential characteristics associated with them. During the 2-year study period, 690 registe...

We tested for life history trade-offs among dormancy, sprouting, and flowering in a seven-year study of a threatened, perennial plant, the small yellow lady’s slipper orchid (Cypripedium calceolus ssp. parviflorum (Salisb.) Fernald). The aboveground states of 629 genets were monitored over seven years in a wet meadow in northeastern Illinois, USA. With mark–recapture statistics, survival, resig...
