Female mate choice behaviour has significant evolutionary consequences, yet its mechanistic origins are not fully understood. Recent studies of female sensory systems have made great strides in identifying internal mechanisms governing female preferences. Only recently, however, have we begun to identify the dynamic genomic response associated with mate choice behaviour. Poeciliids provide a po...

abstract- desert truffles are hypogeous ascomyceteous ectomycorrhizal fungi, occurring in arid and semi-arid ecosystems. a pcr-based method was developed for the identification of 3 major desert truffles of iran: terfezia claveryi, tirmania pinoyi and tirmania nivea based on internal transcribed spacers of rdna. two specific pcr primers were designed for t. claveryi, 4 for t. pinoyi, and 2 for ...

Trees improve the soil quality and their rapid growth in the tropics make agroforestry systems potentially effective for establishing low-input agricultural systems in this region. This study assessed the effects of the biophysical interactions among leguminous trees, weeds, cotton and maize in an alley cropping system. The experiment comprised six treatments: Clitoria + Gliricidia; Acacia ...

Invasive fungal infections with high mortality rate are a growing health concern in hospitals and medical centers. The infection usually occurs in people with compromised immune systems. The purpose of this paper is a review of the most commonly prescribed antifungal drugs for invasive fungal diseases. Antifungals consist of the four main groups; polyenes, azoles, echinocandins and DNA an...

Chinese privet, Ligustrum sinense Lour., is a perennial semi-evergreen shrub that is a serious invasive weed in the United States. Classical biological control offers the best hope for controlling it in an economic, effective, and persistent way. Host speciÞcity of one of the most promising biological control agents of Chinese privet, a ßea beetle, Argopistes tsekooni Chen (Coleoptera: Chrysome...

The rice stink bug, Oebalus pugnax (Fabricius) (Hemiptera: Pentatomidae: Carpocorini), though graminaceous, discriminates among its numerous host grass species. This could represent a feeding preference, it could be related to host suitability for growth and development. To clarify the role of host grass discrimination, two laboratory studies were conducted: (1) free-choice tests to evaluate pr...
