This volume of essays, by a group of scholars from the United States and Great Britain, presents a panoramic look at the study of Franciscan art in late medieval and early Renaissance Italy. In addition to being important case studies, the articles suggest a range of methodologies and interdisciplinary perspectives on important works of art. Senior scholars who have worked in the field for decades are joined by a new generation of researchers in the field. New studies of the Basilica in Assisi as well as innovative looks at early panel paintings and Franciscan stained glass are included. Those who study the Franciscan tradition as well as art historians, historians, literary critics, and theologians will find the studies relevant to their work.

Abstract

Development of stem nematode (Ditylenchus dipsaci) infestations of white clover (Trifolium repens) in artificially established swards and transplanted turfs was monitored at field sites with different mean daily temperatures. In artificial swards the level of nematode infestation was inversely related to mean daily temperature. In transplanted turfs, nematodes caused a 46% reduction in white clover density over an 18-month period; the level of damage was not significantly affected by mean daily temperature although the proportion of clover stolons infested was higher at colder temperatures. Reductions in infestation levels at higher temperatures are probably the result of reduced survival in soil and the upper lethal temperature for nematodes being exceeded more frequently under warmer conditions. Influence de la temperature sur l'infestation, dans des pelouses, du trefle blanc (Trifolium repens) par le nematode des tiges (Ditylenchus dipsaci) - Le developpement de l'infestation du trefle blanc (Trifolium repens) par le nematode des tiges (Ditylenchus dipsaci) dans des pelouses artificielles ou des gazons transplantes a ete controlee, au champ, a differentes temperatures journalieres. Dans les pelouses artificielles, le niveau de l'infestation par le nematode est inversement proportionnel a la temperature journaliere moyenne. Dans le cas des gazons transplantes, et sur une periode de 18 mois, les nematodes reduisent de 46% la densite des trefles blancs; le niveau des degats n'est pas significativement affecte par la temperature moyenne journaliere quoique la proportion de stolons de trefle infestes soit plus elevee aux temperatures les plus basses. La diminution de l'infestation aux temperatures elevees est probablement due a une moindre survie du nematode dans le sol et au fait que les temperatures letales pour lui soient plus frequemment depassees dans des conditions de plus grande chaleur.
