GIS technology, while offering libraries a valuable new resource, will require the assistance of experienced practitioners. These persons may be from other libraries or academic departments and this ...article suggests sources for this expertise and encourages libraries to seek them out.
Duende has long been a fixture of the gitano lifescape in Andalusia, Spain, and is often invoked in relation to flamenco performance with such variance in meaning that it is difficult to attain an ...understanding of what duende really is, and more importantly, what it means to contemporary flamenco performers. The word is often portrayed in spiritual and poetic terms, which are evocative but imprecise in definition. This thesis seeks to construct an understanding of duende that is derived from both the traditional gitano setting and the modern context of commercial performance, one that explains the phenomenon through the lenses of ethnomusicological theories of embodiment, the psychology of optimal experience (flow), and the neuroscience of musical experience. As a by-product of coming to an understanding of duende , I have constructed a theory of deep playing, which intersects with these phenomena. Deep playing privileges the experience of the performer, and describes a processual phenomenon with specific conditions and variables, with the key indicators expressed by Autonomic Nervous System arousal, and the climax demonstrated through a flood of chemical neurotransmitters, creating a feeling of transcendence.
We used cohort analyses and population cohort matrices to model a wild turkey (Meleagris gallopavo silvestris) population under perturbed (i.e., man-induced flooding on 3-yr intervals) and ...unperturbed (i.e., non-flood) conditions. The net reproductive rate$(R_{o})$of a cohort in which reproduction in the hatching-year (HY) age class was perturbed by flooding dropped to 0.460 from Ro= 1.383 for unperturbed cohorts. The Roof cohorts in which only after-hatching-year (AHY) age classes were exposed to flooding was >1.0. Cohort analyses demonstrated the importance to the population of nesting by HY hens and the significant effects on cohort reproductive potential of exposing the HY age class to flooding. Evaluation of population cohort matrices also suggested that flooding on a 3-year interval precludes sufficient reproduction to maintain this wild turkey population.
Early-successional habitats across the southeast United States have declined considerably in recent years amid rising human population growth and associated development. Recognizing the declining ...wildlife populations associated with early-successional habitats and the need for influence over habitat on private land, the North Carolina Wildlife Resources Commission established the Cooperative Upland Habitat Restoration and Enhancement (CURE) Program in August 2000. The program targets private landowners in 3 select regions of the state (Upper Coastal Plain I, Upper Coastal Plain II, and Western Piedmont). Survey research was conducted in the 3 CURE Program areas to 1) evaluate demographic and landownership attributes of private landowners and associated land-use characteristics, 2) assess regional differences in landowner attitudes and behavior toward wildlife management on private land, 3) identify landowner attributes related to regional differences in attitude or behavior, and 4) evaluate how regional differences will impact future CURE Program guidelines. Landowner attitudes toward wildlife in North Carolina are closely linked to property use and reliance on land for direct economic income (i.e., agricultural production). Landowners who depended on their property for earned annual income were less likely to consider the aesthetic or intrinsic value of wildlife on their land than those who did not rely on their land for income. For some landowners, financial incentives alone appeared sufficient to encourage participation in the CURE Program. Other landowners were less interested in financial rewards. For these landowners, alternative forms of encouragement, such as partnerships with agencies and organizations, might be more effective. Understanding variability in landowner attitudes and behavior toward wildlife habitat is critical to the success of private-land wildlife habitat management programs. In North Carolina the success of the CURE Program will depend on tailoring the program to fit regional differences in landowner values, attitudes, and behavior.
The epizootiology of anatid herpesvirus 1 (AHV-1) infection in waterfowl is poorly understood but apparently involves persistence of the virus in latently infected birds. Epornitics have often ...occurred in captive waterfowl or semiwild ducks in parklike settings, and many wildlife professionals conclude that such ducks may be the source of infection for wild waterfowl. We assessed the prevalence of latent infection and viral shedding from four groups of waterfowl: naturally occurring populations of native waterfowl, captive-reared waterfowl released for shooting, introduced nonmigratory waterfowl (e.g., resident, wild Mallards; Anas platyrhynchos), and semiwild peridomestic waterfowl (e.g., park ducks) in North Carolina and Florida, USA from 2004 to 2009. A nested PCR assay was used to detect viral DNA in trigeminal ganglia and cloacal swabs. Detection of viral DNA in trigeminal ganglia, but not cloacal swabs, was assumed to indicate latent infection, whereas PCR-positive cloacal swabs indicated active shedding of the virus. We collected 2,045 samples from 23 species of native, wild waterfowl, and detected latent infections in nine species. Wild Northern Pintails (Anas acuta), a species reportedly resistant to the virus, had the highest prevalence (8.1%). However, low prevalences were identified in other waterfowl from various families. Cloacal shedding was rarely detected (0.1% prevalence) among native waterfowl and was observed in one Blue-winged Teal (Anas discors) and one Mottled Duck (Anas fulvigula). All captive-reared, released waterfowl (n=13) collected were Mallards and one was latently infected, suggesting that these birds could also serve as a source of AHV-1 for naive waterfowl. All nonmigratory waterfowl sampled (n=90) were also Mallards. None of the resident Mallards were shedding virus, but one was latently infected. The peridomestic waterfowl sampled included breeds of domestic Mallard (n=6) and Muscovy Ducks (Cairina moschata; n=73). One peridomestic Mallard and four Muscovy Ducks were shedding virus at the time they were sampled, but no latently infected, asymptomatic carriers were identified.
The development of six mixed-species, even-aged stands was reconstructed in the eastern Washington Cascade Range. All stands were within the Grand Fir Climax Series and began following stand ...replacement disturbances. Western larch (Larix occidentalis Nutt.) and lodgepole pine (Pinus contorta Dougl. ex Loud.), when present, formed an upper stratum over interior Douglas-fir (Pseudotsuga menziesii var. glauca (Beissn.) Franco) and grand fir (Abies grandis (Dougl.) Lindl.) in all six stands. Establishment patterns and species composition affected stand development patterns. Douglas-fir benefitted from the absence of lodgepole pine; grand fir benefitted from the absence of Douglas-fir, but apparently not from the absence of lodgepole pine. Lodgepole pine had faster initial diameter growth rates than western larch when it became established relatively early and in large numbers.
