Theory predicts shifts in the magnitude and direction of biodiversity effects on ecosystem function (BEF) over succession, but this theory remains largely untested. We studied the relationship between aboveground tree biomass dynamics (Δbiomass) and multiple dimensions of biodiversity over 8-16 years in eight successional rainforests. We tested whether successional changes in diversity-Δbiomass...
Introduction Both biogeographic (for example, latitude) and local (for example, soil) processes determine composition and succession of biotic communities. Postfire succession of vegetation has been studied intensively in chaparral and coastal sage scrub. Fewer studies have examined postfire succession of animals, even though fires can drastically alter their abundance and diversity (Ahlgren an...
Ecological restoration of mining areas has mainly focused on the succession dynamics of vegetation and the fate of microbial communities remains poorly understood. We examined changes in soil characteristics and plant and microbial communities with increasing reclamation period in an open coal mine. Bacterial, archaeal and fungal communities were assessed by tag-encoded 454 pyrosequencing. At t...
Transfer of code ownership or succession is a crucial ingredient in open source projects because the source code tends to be reused and in global software development because products are offshored or outsourced. Measuring and studying such transfer can highlight the way organizations adapt to new product structure and change the received product in response. We evaluate several measures of suc...
When a candidate for the top management position is pre-associated with the firm, prior information exists that partially reveals his suitability for the position. In a dynamic framework of job matching, we show that in the presence of such pre-appointment information, the firm’s decision on managerial appointment differs in significant ways between inside and outside candidates. The difference...
