In dryland environments, where rain is scarce and unpredictable, ecological restoration of degraded ecosystems presents significant challenges. Several techniques based on the functioning have emerged, emphasizing interactions that promote natural succession. other use soil fauna has been recommended to help accelerate succession due its effects maintenance improvement physical–chemical biologi...
The main driver of the Carpathian landscape is process natural forest succession on semi-natural meadows unique to region. Moreover, these mountain contribute ecosystem services, although increasing areas are recommended by current international policy agendas. purpose this study was examine impact in Polish part changes soil organic carbon and assess influence different properties content acro...
Why should one find a particular set of small mammals at any site? This question is the heart community ecology, and while no definitive conclusive answer can yet be provided, this paper does summarize body research that has explored, I think clarified, some factors influence which species occur where when. The impacts disturbances such as wildfire sand mining are examined, along with regenerat...
• What is the range and pattern of variability in landscape structure under “natural” and anthropogenic disturbance regimes? RMLANDS provides a mechanistic approach for evaluating disturbance and succession processes over broad spatial (100,000's of ha) and temporal scales (100's of years) not possible or practical with empirical field studies. Moreover, RMLANDS allows us to ask “what if” quest...
A total of 38 fungal taxa were identified on senescent untreated and autoclaved Castanopsis fissa leaves during a 4-month study period. Seventy-six percent of the fungal genera found in this survey have not previously been recorded from Castanopsis. Frequency and time of occurrence of fungal taxa occurring on untreated senescent leaves were clustered into four groups when analyzed by cluster an...
In this paper we will give a formal description of succession rules in terms of linear operators satisfying certain conditions. This representation allows us to introduce a system of well-deened operations into the set of succession rules and then to tackle problems of combinato-rial enumeration simply by using operators instead of generating functions. Finally we will suggest several open prob...
The greatest challenge facing the indigenisation of African economies is the problem of succession. A Mean businesses have always died with their founders. This phenomenon is caused by failure by the business founders to properly plan for the succession. Drawing from a case study of 10 smallscale indigenous businesses in Zimbabwe and from literature on African indigenous businesses, this articl...
Abstract I argue that Hume’s philosophy of time is relationist in the following two senses. 1) Standard definition relationism . Time a succession indivisible moments. Hence there no independent change. relational, not substantial feature world. 2) Rigid There evidence uniform natural standard for synchronization clocks. No absolute temporal metric available. are countless times, and privileged...
