Chimpanzees (Pan troglodytes) hunt various primates, but concentrate on red colobus monkeys (Piliocolobus spp.) wherever the two species are sympatric. The extraordinarily large Ngogo chimpanzee community in Kibale National Park, Uganda, preys heavily on the local population of red colobus (P. tephrosceles). Census data showed a steep decline in this population in the center of the chimpanzees'...

Humans have hunted wildlife in Central Africa for millennia. Today, however, many species are being rapidly extirpated and sanctuaries for wildlife are dwindling. Almost all Central Africa's forests are now accessible to hunters. Drastic declines of large mammals have been caused in the past 20 years by the commercial trade for meat or ivory. We review a growing body of empirical data which sho...

The generation of a 24-fs fibre-coupled electro-optic-modulation (EO) comb at 1.5 μm with 25-GHz repetition rate, which is the shortest pulse, demonstrated. authors also generated 2/3-octave spanning supercontinuum spectrum using precise dispersion-controlled silicon nitride waveguides. This method can open new horizons to generate compact and robust carrier-envelope-offset-locked EO comb.

Ungulate mortality profiles are commonly used to study Neanderthal subsistence strategies. To assess the hunting strategies used by Neanderthals, we studied the ages at death of the cervids and equids found in levels E, H, I, Ja, Jb, K, L and M of the Abric Romaní sequence. These levels date between 43.2 ± 1.1 ka BP (14C AMS) and 54.5 ± 1.7 ka BP (U-series). The degree of eruption and developme...

Hunting for wild animals is stimulated by the many different human uses of faunal resources, and these animals constitute important subsistence items in local communities in the Caatinga region. In order to gain access to these resources, hunters have developed a series of techniques and strategies that are described in the present work. The principal hunting techniques encountered were: waitin...

Traill et al. (1) conclude that the “decline in body mass of the bighorn population is largely attributable to demographic change and environmental factors” and “expect our conclusions to hold for horn length too.” Three of us (D.W.C., M.F.-B., and F.P.) provided data from the Ram Mountain bighorn sheep population for this article, but withdrew from authorship because of major concerns about th...

Femtosecond lasers with a repetition rate of approximately I GHz are commonly used frequency comb generators for precise optical frequency metrology. They are conveniently compact, yield unambiguous frequency readings with the help of a commercial wavemeter, and can yield greater heterodyne beat signals against a cw laser than systems with lower repetition rates. This chapter reviews the techno...

in arabic poetry, the device of repetition functions at two levels: form and meaning. in form, repetition makes for musical richness, and in meaning, it makes for emphasis. the present article is a study of repetition in “an address from the market of idleness” by palestinian poet samä«h al-qäsim. the poem depicts actual and possible palestinian sufferings inflicted by israelis and stresse...
