Prickly pear (Opuntia sp.) is both a benefit and hindrance to the livestock industry in the southwestern U.S. It competes with herbaceous forage but is sometimes used as emergency feed during drought. Spineless prickly pear (0. fiscus-indica Engelm. and 0. rufida Engelm.) has been planted in some regions of the southwest but little is known about its nutritional value. Our objectives were to de...

Pear is one of the most important fruit species grown in temperate zones globe. Besides production, pear are highly valued forestry and agroforestry systems; landscaping, as ornamental features; fruits ecological value, other areas. The Pyrus species, obtained from a gene bank, were evaluated for different morphological traits trees, leaves, flowers, fruits, well their responses to attacks prin...

The following brief description of the Princeton Engineering Anomalies Research (PEAR) Remote Perception program has been prepared at the invitation of the Editor, in order to augment this special report section of the Journal with information about another substantial database of experiments relevant to those of SRI and SAIC. Given Utts' attention to the importance of replication (Section 3.4)...

The objective of this study was to evaluate the best level of inclusion of cactus pear in the ensiling of elephant grass Brazil seeds (BRS) capiaçu (Pennisetum purpureum), its effects on fermentative characteristics; and nutritional value. Experimental treatments consisted of BRS capiaçu grass silage with five levels of inclusion of cactus pear (0, 5, 10, 15 and 20% inclusion as fresh ...

 Objectives to target: This relates to asking ‘Where to go?’, whereas Tools and Strategies below relate to ‘How to get there?’ Breeding objectives describe the type of animal that we might want to develop, or, more commonly, describe the utility of marginal genetic changes in each trait of commercial value. However, there is increasing concern about loss of genetic diversity, both within and b...

Studieswere conducted in apple,MalusdomesticaBorkhausen, orchards to evaluate the attractiveness of the kairomone, ethyl (E, Z)-2,4-decadienoate (pear ester), loaded at various rates into gray halobutyl septa, to adult codling moth, Cydia pomonella L. All studies were conducted in orchards treated with sex pheromone mating disruption. Lure loadings from 0.01 g to 50.0 mg were evaluated in 12 or...
