Landscape constraints on functional diversity of birds and insects in tropical agroecosystems.

Abstract: In this paper, we analyze databases [corrected] on birds and insects to assess patterns of functional diversity in human-dominated landscapes in the tropics. A perspective from developed landscapes is essential for understanding remnant natural ecosystems, because most species experience their surroundings at spatial scales beyond the plot level, and spillover between natural and managed ecosystems is common. Agricultural bird species have greater habitat and diet breadth than forest species. Based on a global data base, bird assemblages in tropical agroforest ecosystems were composed of disproportionately more frugivorous and nectarivorous, but fewer insectivorous bird species compared with forest. Similarly, insect predators of plant-feeding arthropods were more diverse in Ecuadorian agroforest and forest compared with rice and pasture, while, in Indonesia, bee diversity was also higher in forested habitats. Hence, diversity of insectivorous birds and insect predators as well as bee pollinators declined with agricultural transformation. In contrast, with increasing agricultural intensification, avian pollinators and seed dispersers initially increase then decrease in proportion. It is well established that the proximity of agricultural habitats to forests has a strong influence on the functional diversity of agroecosystems. Community similarity is higher among agricultural systems than in natural habitats and higher in simple than in complex landscapes for both birds and insects, so natural communities, low-intensity agriculture, and heterogeneous landscapes appear to be critical in the preservation of beta diversity. We require a better understanding of the relative role of landscape composition and the spatial configuration of landscape elements in affecting spillover of functionally important species across managed and natural habitats. This is important for data-based management of tropical human-dominated landscapes sustaining the capacity of communities to reorganize after disturbance and to ensure ecological functioning.

The Development of Cross-Cultural (Mis)Understanding Through Volunteer Tourism

Abstract: Volunteer tourism is an increasingly popular activity in which individuals combine travel with voluntary work. On the whole, existing literature has provided an optimistic view of volunteer tourism, suggesting that it represents a more reciprocal form of tourism and facilitates the development of cross-cultural understanding among participants. However, more recently, it has been argued that if volunteer tourism programmes (VTPs) are not carefully managed, they may lead to cross-cultural misunderstanding and the reinforcement of cultural stereotypes. Through conducting an Appreciative Inquiry into a number of volunteer programmes, this research sought to explore these ideas further and, in particular, identify the role that volunteer tourism sending organisations can play in order to ensure that cross-cultural understanding develops through volunteer tourism. The findings from this research suggest that the development of cross-cultural understanding should be perceived as a goal of volunteer tourism rath...

Prevalence of traumatic brain injury among children, adolescents and young adults: Prospective evidence from a birth cohort

Abstract: Background: Little is known about the incidence and prevalence of traumatic brain injury (TBI), particularly for infants, children and young adults.Primary objective: The purpose of this study was to provide an accurate estimate of the incidence and prevalence of TBIs for individuals between 0–25 years of age.Method and procedures: A birth cohort of 1265 individuals was used, for which information regarding TBI events, both hospitalized and non-hospitalized, had been recorded.Main outcomes and results: The average incidence for this age group ranged from 1.10–2.36 per 100 per year, with an overall prevalence of ∼30%. The most common source of injury was falls for individuals 0–14 years of age and contact sports and motor vehicle accidents for 15–25 year olds. Approximately one third of the individuals who experienced a TBI went on to have one or more additional injuries.Conclusions: The incidence rates reported here are much higher than those previously found. It is clear that TBIs constitute a major heal...

CMS physics technical design report: Addendum on high density QCD with heavy ions

Abstract: This report presents the capabilities of the CMS experiment to explore the rich heavy-ion physics programme offered by the CERN Large Hadron Collider (LHC). The collisions of lead nuclei at energies , will probe quark and gluon matter at unprecedented values of energy density. The prime goal of this research is to study the fundamental theory of the strong interaction ? Quantum Chromodynamics (QCD) ? in extreme conditions of temperature, density and parton momentum fraction (low-x).This report covers in detail the potential of CMS to carry out a series of representative Pb-Pb measurements. These include bulk observables, (charged hadron multiplicity, low pT inclusive hadron identified spectra and elliptic flow) which provide information on the collective properties of the system, as well as perturbative probes such as quarkonia, heavy-quarks, jets and high pT hadrons which yield tomographic information of the hottest and densest phases of the reaction.
