Not all tropical fruits are equally desired by rainforest foragers and some fruit trees get depleted more quickly and carry fruit for shorter periods than others. We investigated whether a ripe-fruit specialist, the chimpanzee (Pan troglodytes verus), arrived earlier at breakfast sites with very ephemeral and highly sought-after fruit, like figs, than sites with less ephemeral fruit that can be...

Rift Valley fever virus (RVFV) is one of the important emerging viral diseases of serious impact in public health and animal hygiene both in human and animal industries. In this study, we developed a monoclonal antibody-based competitive ELISA for the detection of antibodies to RVFV in goats and cattle. The recombinant N protein of RVFV was expressed in E. coli with a six-histidine tag, and the...

Hong Kong is within the tropics and has a seasonal climate. In winter, shores support patches of ephemeral macroalgae and areas of seemingly bare rock close to crevices where molluscan herbivores are abundant. Using a factorial design of herbivore exclusions in areas far and close to crevices, the development of algal assemblages was monitored in mid-shore, cleared areas, in winter. To estimate...

In September 2012, several cows and a calf showed decreased activity, anorexia and fever on Ishigaki Island, Okinawa Prefecture, Japan, and the cases were diagnosed as bovine ephemeral fever (BEF). We isolated BEF virus (BEFV) from one of the affected cows and then determined the complete genome sequence of the G gene, which encodes a class I transmembrane glycoprotein of BEFV. The BEFV isolate...

Bovine ephemeral fever virus (BEFV) is an arthropod-borne rhabdovirus that causes a debilitating disease of cattle in Africa, Asia, and Australia; however, its global geodynamics are poorly understood. An evolutionary analysis of G gene (envelope glycoprotein) ectodomain sequences of 97 BEFV isolates collected from Australia during 1956 to 2012 revealed that all have a single common ancestor an...

We show how personalization techniques can be exploited to implement more adaptive and effective information access systems in electronic publishing. We distinguish persistent (or long term) and ephemeral (or short term) personalization, and we describe how both of them can be profitably applied in information filtering and retrieval systems used, via a specialized Web portal, by physicists in ...

Little Kinyasungwe Catchment within the River Wami Basin of central, semi-arid Tanzania. Groundwater and its replenishment via recharge are critical to sustaining livelihoods poverty alleviation in tropical drylands yet processes by which groundwater is replenished remain inadequately observed resolved. Detailed observations examined from central Tanzania, where Makutapora Wellfield supplies fr...

A primary sewage treatment plant discharges its effluents into Butler Ditch, Oak Openings, Lucas County, Ohio. A marsh habitat near the discharge outlet, high turbidity, sludge covering the stream bed and pungent odor gave reason to believe that the effluent from the sewage treatment plant contaminated the ditch. Water and stream sediment samples were collected from 24 sample locations over a 2...

Abstract The Abrigo de la Quebrada is a Middle Palaeolithic rockshelter located in the Rambla Ahíllas Iberian Range (Valencia, Spain). Archaeological work began 2007 and was completed 2015, reaching substratum uncovering record that spans from MIS 5 to 4/3. data geoarchaeological micromorphological study of site allow us deduce it formed by alluvial contributions ephemeral stream, different sub...
