Flamingo foraging plasticity: ecological drivers and impacts
… of foraging plasticity displayed by Greater Flamingo Phoenicopterus ruber roseus in intertidal sandflat ecosystems in Langebaan Lagoon, South Africa. P. roseus feeds by either (1) creating pits, which involves flamingos stirring up deep sediments with their feet or (2) creating channels, in …

Flamingo predation impacts on benthic communities: effects of spatial gradients
… the effects of spatial gradients on Greater Flamingo (Phoenicopterus ruber) predation impacts on the benthic macrofaunal community structure in an intertidal sandflat ecosystem in South Africa. P. ruber is a benthic filter-feeder known to feed on benthic dwelling invertebrates through pit …

Environmental determinants of greater flamingo foraging behaviour in an estuarine intertidal sandflat
The impact of flamingo predation on the benthic community has been well researched through the use of caging and exclusion experiments. However, there is still very little known about flamingo spatial foraging preferences and the environmental cues that determine them. The purpose of this study was …

Microsatellite-based genetic profiling for the management of wild and captive flamingo populations.
Flamingo species generate tremendous interest whether they are small captive groups or wild populations numbering in the thousands. Genetic pedigrees are invaluable for maintaining maximum genetic diversity in captive, as well as wild, populations. However, presently there is a general lack of …

Flamingo foraging activity as a driver of spatial heterogeneity in Langebaan Lagoon, South Africa
… impacts of different foraging methods used by flamingos on benthic communities. Multivariate and univariate analyses were carried out in order to determine the effects of two different flamingo feeding strategies (pit and channel foraging) on sediment penetrability and macrofaunal community …

Temporal interactions with flamingo foraging plasticity: ecological effects on basal resources and benthic heterogeneity
… and the broader ecological role of Greater Flamingos as predators in marine sedimentary ecosystems. The specific aim was to test the long-term effects of different foraging structure sizes (which is a subtle form of foraging plasticity) on sedimentary assemblages following foraging …

Isolation and Characterization of Polymorphic Loci from the Caribbean Flamingo (Phoenicopterus ruber ruber): New Tools for Wildlife Management
… from a microsatellite-enriched Caribbean flamingo genomic library and used to characterize survey populations of Caribbean and African greater flamingos. In addition, four of these loci were used to verify parentage relationships within a captive-breeding population of African greater …

Assessment of In-situ Corrosion Conditions at Nevada Mechanically Stabilized Earth Wall Sites: Using Electrochemical Soil Characteristics and Linear Polarization Resistance
… an extensive site investigation at I-515/ Flamingo Rd. and a statistical analysis of as-built soil records along with a preliminary investigation for I-15/ Cheyenne Blvd. These studies form the foundation for this investigation of in-situ corrosion conditions. Seven MSE wall sites were …

Hexagonal packing of Drosophila wing epithelial cells by the Planar Cell Polarity pathway
… show that the Planar Cell Polarity protein Flamingo can recruit the exocyst component Sec5. Sec5 vesicles also co-localizes with E-cadherin and Flamingo. Based on these observations we propose that during the hexagonal repacking of the wing epithelium these proteins polarize the trafficking …

An integrated systems methodology for pedestrian traffic flow analysis
… study of the signalized at-grade intersection of Flamingo Road and Las Vegas Boulevard South in the Las Vegas valley area of Clark County, Nevada is presented to demonstrate the application of the methodology. Comments and recommendations regarding potential utilization of the research product …

The acute effect of percusive therapy on postural stability and muscle activation in people with chronic ankle instability and controls
… bilateral asymmetry between DOM and NON in Flamingo test (expressed as %). Especially HYPO group revealed risen asymmetry after PT when compared to CNPO (p=0.007), CNP (p=0.015) and CYPO (p=0.05). Key finding was measured significant difference in intragroup parameter between HYP vs. HYPO …

Predation/disturbance effects of greater flamingos (Phoenicopterus ruber) on the benthic communities of two Southern African lagoons
Greater Flamingos, Phoenicopterus ruber, were excluded from intertidal areas of two lagoons and subtidal areas of one of these on the Namibian coastline. Macrofaunal and meiofaunal numbers increased at all exclusion sites, but taxon-specific responses were variable. Both intertidal sites were …

Exploiting inherent robustness and natural dynamics in the control of bipedal walking robots
… These algorithms are implemented on Spring Flamingo, a planar bipedal walking robot, which was designed and built for this thesis. Using these algorithms, the robot can stand and balance, start and stop walking, walk at a range of speeds, and traverse slopes and rolling terrain. …

Confronting modernity: urbanization and American fiction, 1880-1930
… Passos's Manhattan Transfer and Mary Borden's Flamingo: Both are formally experimental yet evince the same contradictory impulses evident in "realist" texts. In chapter five, "At the Heart of the Metropolis/At the Margins of Modernism," I examine the formal disruptions of Nella Larsen's novels …

Genetic and phenotypic analysis of novel South African Avian poxviruses

Local Wnt11 Signalling and its role in coordinating cell behaviour in zebrafish embryos
… In addition, I found that the atypical cadherin Flamingo (Fmi) is required for this process. Fmi accumulates together with Wnt11/Fz7 at sites of cell-cell contact and locally increased cell adhesion, via a mechanism that appears to be independent of known downstream effectors of Wnt11 signalling …

Epidermal growth factor receptor signalling regulates ommatidial rotation during Drosophila eye development
… process. In particular, the atypical cadherin flamingo, a gene known to regulate epithelial planar polarity, appears to play a key role in ommatidial rotation, as its sub-cellular localisation is disturbed in argosroulette mutants. Genetic interactions further implicate non-muscle Myosin II as …
