While there is much new work in the field of communications that challenges such distinctions, many scholars who study the medium still assume a clear and natural separation between fictional and non-fictional television. Falling into the former category are most prime-time shows, specials, movies and other broadcasts serving, it is assumed, primarily as entertainment. Further, many scholars as...

The New World species of Dohrniphora lacking large hind tibial setae are revised, with 139 species recognized, most from the Neotropical Region. Of these, 88 are described as new to science. New synonymies are as follows: D. denticulata Borgmeier is a junior subjective synonym of D. penicillata Borgmeier, D. caverna Disney and D. recurvata Borgmeier are both junior subjective synonyms of D. div...

Ninety-seven yellow mongooses were captured in six different localities in South Africa and blood specimens for rabies antibody determination as well as brain and salivary glands for virus isolation were collected. No rabies virus or antibody to it was detected in any of the specimens. Parallel to the field study, two experimental infections were undertaken in which yellow mongooses were artifi...

The effects of the interaction between the operational sex ratio (OSR) and a resource (i.e. oviposition site) on mating dynamics have rarely been considered. We examined the effect of the resource presence and its interaction, with the effect of OSR on copulation duration in Rhagoletis juglandis, a tephritid fly species characterized by a resource-defence mating system in which males defend ter...

BACKGROUND AND AIMS Mite domatia are small structures on the underside of plant leaves that provide homes for predacious or fungivorous mites. In turn, mites inhabiting domatia defend the plant by consuming leaf herbivores and pathogens, which can result in a domatia-mediated, plant-mite defence mutualism. Several recent studies have suggested that plants receive enhanced benefits when they pro...

Beet necrotic yellow vein virus is the etiological agent of one of the most devastating sugar beet viral diseases: rhizomania. This review describes the molecular biology of the rhizomania disease, the functions of the BNYVV encoded proteins, the consequences of their expression as well as the biology of the BNYVV vector, Polymyxa betae. Root proliferation is an important part of the well-known...
