Diseases of Tropical Perennial Crops: Challenging Problems in Diverse Environments

The world’s oldest ecosystems are found in the tropics. They are diverse, highly evolved, but barely understood. Diseases that impact crops in these regions can be significant contraints to production, especially when they occur in lowland environments with high rainfall and uniform, warm temperatures; respites from disease pressure there are often infrequent. Difficulties in managing diseases ...

Update on Perennial Roots and Lifespan Perennial Roots to Immortality

Maximum lifespan greatly varies among species, and it is not strictly determined; it can change with species evolution. Clonal growth is a major factor governing maximum lifespan. In the plant kingdom, the maximum lifespans described for clonal and nonclonal plants vary by an order of magnitude, with 43,600 and 5,062 years for Lomatia tasmanica and Pinus longaeva, respectively. Nonclonal perenn...

Simulating perennial ryegrass cutting

Perennial ryegrass is one of the most commonly cultivated forage species in Europe, where grazing and mowing (cutting) are used to manage this resource. Cutting can be characterized by its intensity (height) and its frequency. Combinations of these two factors affect mono-species grasslands productivity and could also modify the genotypic composition of heterogeneous populations. Indeed, the hi...

Muslim Intellectuals and the Perennial Philosophy in the Twentieth Century

This paper will examine how Muslim intellectuals, as a result of their attachment to the doctrine of Divine Unity (taw¤hīd), the Quran, Sunnah of the Prophet Muhammad, and the doctrines and methods of Sufism, were largely responsible for the restating of the perennial philosophy in the West in the twentieth century. The article consists of four sections: an introduction to the term 'philosophia...
