It is important to understand how eco-physiological characteristics shift in forests when elucidating the mechanisms underlying species replacement and the process of succession and stabilization. In this study, the dominant species at three typical successional stages (early-, mid-, and late-succession) in the subtropical forests of China were selected. At each stage, we compared the leaf cons...

Forest succession on degraded tropical lands often is slowed by impoverished seed banks and low rates of seed dispersal. Within degraded landscapes, remnant forests are potential seed sources that could enhance nearby forest succession. The spatial extent that forest can influence succession, however, remains largely unstudied. In abandoned agricultural lands in Kibale National Park, Uganda, re...

Global plant trait studies have revealed fundamental trade-offs in plant resource economics. We evaluated such trait trade-offs during secondary succession in two species-rich tropical ecosystems that contrast in precipitation: dry deciduous and wet evergreen forests of Mexico. Species turnover with succession in dry forest largely relates to increasing water availability and in wet forest to d...

Prior reviews of the CEO turnover and succession literature suggest that empirical findings on organizational implications continue to be equivocal. In this paper, we develop a conceptual framework for examining the impact of CEO turnover and succession on organizational capabilities. Using the social network perspective as a theoretical lens, we identify conditions in which CEO turnover is exp...

Unraveling the drivers of community structure and succession in response to environmental change is a central goal in ecology. Although the mechanisms shaping community structure have been intensively examined, those controlling ecological succession remain elusive. To understand the relative importance of stochastic and deterministic processes in mediating microbial community succession, a uni...

The ecological mechanisms driving community succession are widely debated, particularly for microorganisms. While successional soil microbial communities are known to undergo predictable changes in structure concomitant with shifts in a variety of edaphic properties, the causal mechanisms underlying these patterns are poorly understood. Thus, to specifically isolate how nutrients--important dri...

Many farm businesses are managed as one-man shows. Little financial information and almost none of the business decision-making functions are shared with others in the business or the family. There is seldom a plan for management succession or for developing backup management. Thus, when something happens to the only decision maker, many firms either fail or experience a traumatic adjustment pr...

This study estimates the value of farmers’ stated succession plans in predicting revealed succession decisions. The stated succession plan exists when a farmer answers in a survey questionnaire that the farm is going to be transferred to a new entrant within a five year period. The succession is revealed when the farm is transferred to a successor. The stated and revealed behaviour is estimated...
