Question: How does vegetation develop during the initial period following severe wildfire in managed forests? Location: Southwestern Oregon, USA. Methods: In severely burned plantations, dynamics of (1) shrub, herbaceous, and cryptogam richness; (2) cover; (3) topographic, overstory, and site influences were characterized on two contrasting aspects 2 to 4 years following fire. Analysis of varia...

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...

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...

In this paper we present a method to pass from a given recurrence relation with constant coefficients (in short, a C-finite recurrence) to a finite succession rule defining the same number sequence. Our method consists in two steps: first, we transform the given recurrence relation into an extended succession rule, then we provide a series of operations to reduce such an extended succession rul...

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...

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...

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...

We introduce in this paper a new interacting particle system intended to model an example of ecological succession involving two species: Pteridium aquilinum L. commonly called bracken and Fagus sylvatica L. or european beech. The species both compete over vacant sites, assimilated to windfall, according to fundamentally different evolutionary strategies. Our main objective is to exhibit phase ...

The mam plant communities of ultramafic (serpentine) outcrops of a Mediterranean area in central Italy are described and their successional pathway discussed. Four vegetation stages are distinguished: a) an endemic garigue stage, with high percentage of exposed rocky soil belonging to Armerio-Alyssetum bertolonii; b) a garigue stage similar to the previous one but with several Mediterranean eve...
