description: Inflammation and oxidative stress are crucial in ischemic stroke. Ephedrine (EPH) has been proven to have anti-inflammatory and anti-oxidative stress effects. The present study analyzes whether EPH possessed neuroprotective effects and explored the underlying mechanisms of EPH based on an experimental model of middle cerebral artery occlusion (MCAO). We found that intraperitoneal injection with EPH attenuated the neurological deficit, cerebral infarction, and cerebral edema induced by MCAO in rats. Besides, EPH treatment alleviated MCAO-induced brain tissue damage and morphological abnormality, as well as neuronal loss. Moreover, EPH treatment upregulated GPx and CAT activity and downregulated MDA and NO content. EPH also evidently decreased the levels of IL-6 and TNF-α but increased IL-4 and IL-10 levels. Of note, EPH treatment promoted the phosphorylation of PI3K and AKT proteins in MCAO rats. Furthermore, administration of PI3K/AKT pathway inhibitor LY294002 abolished the beneficial effects of EPH. These results confirmed that EPH alleviated brain injury induced by MCAO via activating PI3K/AKT signaling pathway.

description: We find low energy equivalences between $N=2$ supersymmetric gauge theories with different simple gauge groups with and without matter. We give a construction of equivalences based on subgroups and find all examples with maximal simple subgroups. This is used to solve some theories with exceptional gauge groups $G_2$ and $F_4$. We are also able to solve an $E_6$ theory on a codimension one submanifold of its moduli space.

description: In this work, we study a molecular graphene model on the top of a superconductor in the presence of pseudomagnetic fields induced by coplanar strain fields. With the pseudomagnetic fields and the attractive interaction induced from the substrate, a flat band superconductor can be achieved according to mean field analysis on the effective Hamiltonian. Based on a semiclassical approximation, we first show that the orbital limit is hugely enhanced by the pseudomagnetic fields. The physical reason is that the orbital angular momenta locking at $K$ and $K'$ valleys due to the pseudomagnetic fields suppress the orbital magnetization from external magnetic fields. Considering the vanishing band width in this system, we then study the effects of Gaussian fluctuations in both Hartree and pairing channels. We show that in the dilute limit, the phase transition is dominated by collective modes with critical temperatures much lower than the mean field results. At half filling, our method gives no corrections to the mean field critical temperatures.

Study of neutrino-induced neutral current neutral pion production in the T2K near detector
Creators: name: Short, Samantha
Publisher: name: Imperial College London
Year: 2013

description: The T2K experiment is a long baseline neutrino oscillation experiment. The most intense accelerator muon neutrino beam ever built is produced at the J-PARC facility in Tokai, located on the east coast of Japan, and directed (2.5 [degrees] off -axis) toward the Super-Kamiokande water Cherenkov detector, located 295 km away in the mountains of western Japan. For the current T2K [Symbol appears here. To view, please open pdf attachment]e appearance analysis, 23% of the background at Super- Kamiokande is from neutral current interactions that produce one π0 in the final state (NC 1π0). This study uses ND280 Run 2 data totalling 7.832 x 10 [to the power of 19] POT and selects neutrino-induced NC 1π0 interactions in FGD1 and FGD2 where both π0 decay photons convert in the barrel and downstream ECAL. Overall, neglecting photon reconstruction efficiency, an efficiency of 22% and purity of 16% is obtained. For the case where both π0 decay photons convert in the downstream (barrel) ECAL an efficiency of 33% (12%) and purity of 43% (9%) is achieved. When one photon converts in the barrel ECAL and the other in the downstream ECAL the efficiency (purity) is 29% (16%). Systematic uncertainties arising from cross-section model parameters and final state interactions, the neutrino flux prediction and the shape discrepancy between ECAL variables in data and MC are evaluated. The predicted total number of events when both photons convert in the downstream and barrel ECAL is 7.1± 2.3 (syst)± 0.5 (stat) and 31.6± 8.9 (syst) ±1.2 (stat), respectively. Whereas when one decay photon is reconstructed in the barrel ECAL and the other in the downstream ECAL the expected number of events is 38.1± 8.7 (syst) ±1.3 (stat). The selected number of events in data is 5, 22 and 31, respectively, which agrees with the prediction within errors. The calibration of the time offsets for the barrel and downstream ECAL is also presented in this thesis. The application of this calibration reduces the timing resolution from 9 ns to approximately 2.5 ns, for high charge hits.

Cosmological Perturbation Theory and the Spherical Collapse model - III. The Velocity divergence field and the $Ω$ dependence

Year: 1998
Subjects: subject: Astrophysics (astro-ph)

description: Cosmological Perturbation Theory (PT) is a useful tool to study the cumulants of the density and velocity fields in the large scale structure of the Universe. In Papers I & II of this series we saw that the Spherical Collapse (SC) model provides with the exact solution to PT at tree-level and gives a good approximation to the loop corrections (next to leading orders), indicating negligible tidal effects. Here, we derive predictions for the (smoothed) cumulants of the velocity divergence field $θ\equiv \nabla\cdot\vv$ for an irrotational fluid in the SC model. By comparing with the exact analytic results by Scoccimarro & Frieman (1996), it is shown that, at least for the unsmoothed case, the loop corrections to the cumulants of $θ$ are dominated by tidal effects. However, most of the tidal contribution seems to cancel out when computing the hierarchical ratios, $T_J = { / ^{J-1}}$. We also extend the work presented in Papers I & II to give predictions for the cumulants of the density and velocity divergence fields in non-flat spaces. In particular, we show the equivalence between the spherically symmetric solution to the equations of motion in the SC model (given in terms of the density) and that of the Lagrangian PT approach (in terms of the displacement field). It is shown that the $Ω$-dependence is very weak for both cosmic fields even at one-loop (a 10% effect at most), except for the overall factor $f(Ω)$ that couples to the velocity divergence.

Riemanns Fotografien dokumentieren aber auch andere Orte. Seine Aufnahmen von leeren, wüsten Ost-Berliner Hinterhöfen zeugen von Verfall, Einsamkeit und Beengung. Sie suggerieren Vernachlässigung, von Gebäuden wie von Menschen. Die Fotos lehren uns zudem, wie Anspruch und Wirklichkeit im DDR-Alltag auseinanderklafften.

description: Previously matrix model actions for ``fuzzy'' fields have been proposed using non-commutative geometry. They retained ``topological'' properties extremely well, being capable of describing instantons, $θ$--states, the chiral anomaly, and even chiral fermions with no ``doubling''. Here, we demonstrate that the standard scalar and spinor actions on a $d$--dimensional manifold are recovered from such actions in the limit of large matrices if their normalizations are correctly scaled as the limit is taken.

description: We consider Einstein gravity in AdS in the presence of a deformed conformal boundary metric, in the limit of large spacetime dimension. At leading order we find a new set of effective near-horizon equations. These can be understood as covariant generalisations of the undeformed equations with new source terms due to the curvature. We show that these equations are given by the conservation of the exact second-order Landau-frame hydrodynamic stress tensor. No derivative expansions are invoked in this identification. We use the new equations to study CFTs with 2d lattice deformations, computing their quasi-normal mode spectra and thermal conductivities, both numerically and analytically to quartic order in small lattice amplitude. Many of our results also apply to asymptotically flat spacetimes.

Systematic methods for solvent design : towards better reactive processes
Creators: name: Siougkrou, Eirini
Publisher: name: Imperial College London
Year: 2014

description: The focus of this thesis is the development of novel methodologies for systematic identification of optimal solvents for chemical reactions. Two aspects are considered: the integrated solvent and process design using a mixed solvent, and the design of an optimal solvent using ab initio methods that do not rely on experimental data. A methodology is developed for the integrated design of a CO2-expanded solvent in a reaction process. Posing as objective function the cost of the process, for a defined production rate, an optimisation problem is formulated, with decision variables that include the organic co-solvent, the composition and the mass of the mixed solvent. Emphasis is placed on the prediction of the reaction rate, for which the solvatochromic equation combined with a preferential solvation model are used, and on solid-vapour-liquid phase equilibrium, for which the group-contribution volume translated Peng-Robinson equation of state is used. The proposed methodology is applied to the Diels-Alder reaction of anthracene and 4-phenyl-1,2,4-triazoline-3,5-dione (PTAD), and three CO2-expanded solvents are considered (acetone, acetonitrile and methanol). Acetonitrile and acetone are found to offer good performance over a range of CO2 concentrations. The importance of taking into account multiple process performance indicators, when designing gas-expanded liquids, is highlighted. As a further step toward systematic solvent design approaches that are not limited by the availability of experimental data and consider a large number of candidate solvents, an ab initio methodology is developed for the design of optimal solvents for reactions. The developed method combines quantum mechanical calculations with a computer-aided molecular design formulation. In order to limit the number of QM calculations but also retain accuracy and ensure convergence, the Kriging approach is used. Kriging is a response surface approach, which has recently attracted a lot of attention because it is an exact extrapolator with a statistical interpretation which makes it stand out from other methods. The proposed approach is used successfully to identify promising solvents for the Menschutkin reaction of phenacyl bromide and pyridine and the Cope elimination of methylamine oxide. The use of Kriging as the surrogate model is found to lead to improved solvents when compared to the simpler solvatochromic equation used in previous work.

description: We present a two dimensional map of the gas temperature distribution in the Centaurus cluster, based on ASCA observations derived using a novel approach to account for the energy dependent point spread function. Along with a cool region, centered on NGC4696, asymmetric temperature variations of moderate amplitude are detected. The hottest region roughly coincides with the position of the second brightest galaxy NGC4709, known to be the dominant galaxy of one of the subgroups in the Centaurus cluster. ROSAT images show faint surface brightness emission also centered on this galaxy. The imaging and spectral results suggest that a subcluster, centered on NGC4709 is merging with the main cluster centered on NGC4696, in agreement with the earlier suggestion by Lucey et al. (1986) that these two systems are located at the same distance despite their different line-of-sight velocities.

description: Humans can experience fake body parts as theirs just by simple visuo-tactile synchronous stimulation. This body-illusion is accompanied by a drift in the perception of the real limb towards the fake limb, suggesting an update of body estimation resulting from stimulation. This work compares body limb drifting patterns of human participants, in a rubber hand illusion experiment, with the end-effector estimation displacement of a multisensory robotic arm enabled with predictive processing perception. Results show similar drifting patterns in both human and robot experiments, and they also suggest that the perceptual drift is due to prediction error fusion, rather than hypothesis selection. We present body inference through prediction error minimization as one single process that unites predictive coding and causal inference and that it is responsible for the effects in perception when we are subjected to intermodal sensory perturbations.

Computational Proteomics Using Network-Based Strategies
Creators: name: Goh, Wen
Publisher: name: Imperial College London
Year: 2013

description: This thesis examines the productive application of networks towards proteomics, with a specific biological focus on liver cancer. Contempory proteomics (shot- gun) is plagued by coverage and consistency issues. These can be resolved via network-based approaches. The application of 3 classes of network-based approaches are examined: A traditional cluster based approach termed Proteomics Expansion Pipeline), a generalization of PEP termed Maxlink and a feature-based approach termed Proteomics Signature Profiling. PEP is an improvement on prevailing cluster-based approaches. It uses a state- of-the-art cluster identification algorithm as well as network-cleaning approaches to identify the critical network regions indicated by the liver cancer data set. The top PARP1 associated-cluster was identified and independently validated. Maxlink allows identification of undetected proteins based on the number of links to identified differential proteins. It is more sensitive than PEP due to more relaxed requirements. Here, the novel roles of ARRB1/2 and ACTB are identified and discussed in the context of liver cancer. Both PEP and Maxlink are unable to deal with consistency issues, PSP is the first method able to deal with both, and is termed feature-based since the network- based clusters it uses are predicted independently of the data. It is also capable of using real complexes or predicted pathway subnets. By combining pathways and complexes, a novel basis of liver cancer progression implicating nucleotide pool imbalance aggravated by mutations of key DNA repair complexes was identified. Finally, comparative evaluations suggested that pure network-based methods are vastly outperformed by feature-based network methods utilizing real complexes. This is indicative that the quality of current networks are insufficient to provide strong biological rigor for data analysis, and should be carefully evaluated before further validations.

description: [transcription] Monsieur,
Je vous remercie des éclaircissements que vous m’avez donnés sur les deux questions que j’ai pris la liberté de vous proposer. Je vois que nous nous réunissons sur un point essentiel qui est que la ville de Marseille avait été réduite en préfecture. Si je n’ai pas combattu le sentiment de ceux qui expliquent praefectus produumvir par vice duumvir, ce n’est pas que je doute qu’il y ait eu du temps des Romains un préfet à Marseille, mais j’étais embarrassé par l’ordre dans lequel les titres de Macrinus étaient arrangés. Je ne pouvais pas concevoir qu’il eut été préfet et ensuite vice duumvir, puisque dans les préfectures il n’y avait ni duumvirs, ni sextumvirs. J’aurais parlé d’une manière plus affirmative si l’on avait mis produumviro quinquennali, et ensuite praefecto. J’aurais vu que Marseille, après avoir eu ses magistrats municipaux, avait été réduite en préfecture et que l’un d’eux était devenu préfet. Cependant, je [fol. 99 v] fais assez entrevoir page 25 que c’est là mon sentiment. Vous avez fixé mes doutes sur les mots Lictori Decurio Tertio & c. et je suis toujours satisfait de vos réponses. Je l’ai été également de l’explication que vous m’avez donnée des deux inscriptions que je vous avais envoyées. La manière dont vous les restituez est très vraisemblable. Votre lettre est arrivée ici pendant mon absence et je me hâte de vous faire mes remerciements. J’étais à Lérins dont je suis allé visiter les archives. J’en ai vu quelques autres sur ma route et je compte partir dans moins de 15 jours pour aller faire imprimer le 2nd volume à Paris. Je vous y offre mes services et vous prie d’être toujours convaincu qu’on ne peut vous aimer et vous estimer davantage.

description: A quadrature rule of a measure $μ$ on the real line represents a convex combination of finitely many evaluations at points, called nodes, that agrees with integration against $μ$ for all polynomials up to some fixed degree. In this paper, we present a bivariate polynomial whose roots parametrize the nodes of minimal quadrature rules for measures on the real line. We give two symmetric determinantal formulas for this polynomial, which translate the problem of finding the nodes to solving a generalized eigenvalue problem.

description: The current formation models for cluster elliptical galaxies which incorporate a mechanism for the metallicity enhancement of massive ellipticals predict a change in the observed slope of the red sequence of ellipticals as a function of redshift. This change occurs primarily because the metal-rich galaxies become redder faster than the metal-poorer galaxies with increasing age. This effect is most pronounced within ~ 4 Gyr of formation. Observations of the change of the slope of the red sequence with redshift may thus be used to constrain the formation epoch for galaxy clusters. We examine the red sequence of cluster ellipticals using publicly available HST imaging data for a set of six 0.75>z>0.2 clusters, and a sample of 44 Abell clusters at z<0.15 imaged with the KPNO 0.9 m. We compare the derived slopes of the red sequences with a set of cluster-elliptical evolution models and find good agreement. We demonstrate that such a comparison provides a useful constraint on the formation epoch for clusters, which can be made independently from considerations of absolute color evolution and scatter in the red sequence. From our initial comparison of the observed and model slopes as a function of redshift, we conclude, conservatively, that most of the elliptical galaxies in the cores of clusters must form at z>2.0, and that these galaxies are coeval and passively evolving.

The Role of Fundamentals in Asset Pricing
Creators: name: Roberts, Ian
Publisher: name: Imperial College London
Year: 2014

description: This thesis seeks to contribute to the understanding and measurement of the aggregate macroeconomic risks that drive security prices, via three empirical studies. Following Abreu and Brunnermeier (2002), Chapter 2 examines a wide cross-section of global equity markets to test the hypothesis that not only do deviations from fundamentals occur, but it is optimal for an arbitrageur to delay trades that would correct the mispricing. The evidence supports the hypothesis that market prices can and do experience sustained deviations from fundamentals despite the presence of arbitrageurs. Chapter 3 examines the tangled evidence that relates firm-level financial distress to the market, size and value factors of Fama and French (1996). Using panel data it is then shown that exposure to the Fama-French factors can be linked to distress risk, which demonstrates a link between priced aggregate macroeconomic risks and the financial performance of individual firms. Frazzini & Pedersen (2013)'s Betting-Against-Beta (BAB) factor is theorized to occur due to the leverage constraints of a subset of the population of investors. Chapter 4 demonstrates that in the post-1990 subsample the premium on the BAB factor is significantly diminished. Furthermore a conditional model using Carhart (1997)'s 4-factors reduces the alpha further, suggesting that part of the anomaly is in fact attributable to conditional exposure to existing factors, rather than market frictions.

description: Calculating the energy spectrum of a quantum system is an important task, for example to analyse reaction rates in drug discovery and catalysis. There has been significant progress in developing algorithms to calculate the ground state energy of molecules on near-term quantum computers. However, calculating excited state energies has attracted comparatively less attention, and it is currently unclear what the optimal method is. We introduce a low depth, variational quantum algorithm to sequentially calculate the excited states of general Hamiltonians. Incorporating a recently proposed technique, we employ the low depth swap test to energetically penalise the ground state, and transform excited states into ground states of modified Hamiltonians. We use variational imaginary time evolution as a subroutine, which deterministically propagates towards the target eigenstate. We discuss how symmetry measurements can mitigate errors in the swap test step. We numerically test our algorithm on Hamiltonians which encode 3SAT optimisation problems of up to 18 qubits, and the electronic structure of the Lithium Hydride molecule. As our algorithm uses only low depth circuits and variational algorithms, it is suitable for use on near-term quantum hardware.

description: The issue of honesty in constructing confidence sets arises in nonparametric regression. While optimal rate in nonparametric estimation can be achieved and utilized to construct sharp confidence sets, severe degradation of confidence level often happens after estimating the degree of smoothness. Similarly, for high-dimensional regression, oracle inequalities for sparse estimators could be utilized to construct sharp confidence sets. Yet, the degree of sparsity itself is unknown and needs to be estimated, which causes the honesty problem. To resolve this issue, we develop a novel method to construct honest confidence sets for sparse high-dimensional linear regression. The key idea in our construction is to separate signals into a strong and a weak group, and then construct confidence sets for each group separately. This is achieved by a projection and shrinkage approach, the latter implemented via Stein estimation and the associated Stein unbiased risk estimate. Our confidence set is honest over the full parameter space without any sparsity constraints, while its size adapts to the optimal rate ofn−1/4when the true parameter is indeed sparse. Moreover, under some form of a separation assumption between the strong and weak signals, the diameter of our confidence set can achieve a faster rate than existing methods. Through extensive numerical comparisons on both simulated and real data, we demonstrate that our method outperforms other competitors with big margins for finite samples, including oracle methods built upon the true sparsity of the underlying model.
Impact of film morphology upon the performance of polymer / fullerene solar cells
Creators: name: Huang, Zheng Gang
Publisher: name: Imperial College London

description: Polymer:fullerene blend microstructure has been recognised as a key, but poorly understood, factor in optimising performance of polymer:fullerene based solar cells. This thesis focuses on investigating the impact of material chemical structure upon the blend microstructure, and thereby on device efficiency and stability for polymer:fullerene solar cells. It will be shown in the first results chapter that polymer fluorination can promote phase segregation in polymer:fullerene blend, limiting its charge generation as demonstrated using transient absorption spectroscopy. The promotion in phase segregation is shown to vary from polymer to polymer. With a careful modification of the polymer backbone, the negative impact of polymer fluorination can be avoided, resulting in an improvement in device performance. The following chapter focuses on the impact of polymer side chain on device performance. Linear side chain for PTTV polymers is found to offer a better polymer:fullerene mixing in comparison to branched side chains, potentially due to its better ability to accommodate fullerene molecules. This subsequently addresses limitations of poor of fullerene exciton dissociation efficiency. The next chapter provides new insights into the effects of polymer molecular weight on device performance. A high molecular weight of two DPP-containing polymers is shown to be beneficial to device performance, by offering a higher degree of material mixing in the polymer:fullerene blend. The last results chapter compares two polymers with different crystallinity in terms of their blend microstructure and device performance upon thermal annealing. It is shown that devices employing a crystalline DPP based polymer exhibits a sharp collapse in efficiency for annealing at temperatures beyond 140 °C, which is assigned to the polymers poorer miscibility with fullerene, making it incapable to suppress fullerene clusters formation. In contrast, an amorphous IDT based polymer shows a smaller decrease in efficiency under the same condition, consistent with its greater miscibility with fullenere.
title: Aspects of the ecology of Ixodes ticks and Borelia burgdorferi at Loch Lomond

Subjects: subject: Ecology, Entomology.

description: With increasing concern being expressed with regard to the disease, Lyme borreliosis, throughout the UK but particularly among those working in rural Scotland, this project was set up to explore the ecology of the causative bacteria, Borrelia burgdorferi in Scotland. The aim was to identify aspects of the ecology which would be amenable to control, thereby reducing the prevalence of the disease in Scotland. A review of the literature established that the bacteria was transmitted in the UK by the tick vector Ixodes ricinus. Its animal hosts remained unknown but small mammals appeared to be the most likely candidates. Deer and birds were also possible reservoir species. The prevalence of the disease would therefore depend upon the size and behaviour of the vector population and the animal reservoir. Control of either may offer control over the disease. This study explored ways of quantifying tick populations and at factors affecting them. It showed for the first time that repeatedly dragging a blanket over the same piece of ground could lead to absolute measurements of population size. It also showed that ticks were more prevalent among the deep blaeberry bush vaccinia myrtilum than in the grass and leaf litter. Tick distribution was also shown to be patchy throughout the woodland. Host studies revealed large numbers of tick to be present on both birds and small mammals. These were nearly all Ixodes ricinus. Small mammal population sizes were measured using mark and recapture methods and bird population measurements carried out previously were used. The role of birds and mammals as tick hosts was then calculated. It was concluded that birds feed up to 10% and that small mammals feed up to 40% of the larval stage of the tick. Neither groups feed a significant number of older stages. Deer probably feed the majority of the remainder of ticks. However, it is noted that with these figures, small mammals could still be the most important animal reservoirs. Immunofluorescence was carried out on some of the ticks. Results were equivocal but supported findings elsewhere showing that B. burgdorferi is ubiquitous throughout tick infested areas of the UK. Lastly this study demonstrated the importance of ticks as potential parasites and vectors in Scotland and that for the sake of conservationists, farmers and tourists, their ecology needs further investigation.
Essays on predictability of equity and bond risk premia
Creators: name: Carnelli, Andrea
Publisher: name: Imperial College London
Year: 2013

description: The purpose of this thesis is to investigate the evidence of return predictability in equity and treasury markets. The first topic investigates the evidence on return predictability from an economic perspective. We use a simple model that incorporates a time varying investment opportunity set into a mean-variance portfolio maximization framework, and derive the optimal capital allocation weights for: (i) a naive strategy based on average realized returns; and (ii) a class of strategies that condition on dividend-price signals. While our data supports in-sample evidence of return predictability, the out-of-sample returns of the naive strategy are higher than those of all conditional portfolio specifications based on a certainty equivalent metric and portfolio turnover. These results suggest that dividendprice predictability offers no economic value to investors. The second topic studies the link between short and long-run risk premia of equity claims. We extract short-term risk premia from contemporaneous information on short-term futures and cash equity markets under the assumption of no arbitrage. Predictability regressions reveal that short-term risk premia capture different information from long-run risk premia. Counter to the intuition that a high price of risk commands high returns, high short-run risk premia on dividend claims predict low returns on the index. While inconsistent with models featuring either habit persistence or long-run risk, the results may be reconciled with some models of uncertainty aversion. The third topic is concerned with monetary policy sources of bond risk premia. Expected monetary policy shocks are extracted from a panel of inflation, GDP growth, and federal funds rates forecasts and using a Taylor rule specification as an identifying assumption. Expected monetary policy shocks are found to be statistically significant predictors of excess returns on bonds, even after controlling for levels and conditional volatilities of macroeconomic activity. The findings are consistent with a long run risk economy where contractionary monetary policy action increases GDP uncertainty.

Investigating ecological impacts of the non-native population of rose-ringed parakeets (Psittacula krameri) in the UK
Creators: name: Peck, Hannah Louise
Publisher: name: Imperial College London
Year: 2013

description: The rose-ringed parakeet has been present in the South East of England since at least the 1970s. However, there is little understanding about the impact that this exotic, gregarious bird has on native wildlife and therefore whether anything should or can be done to restrict potential impacts. The aim of this thesis is to provide an updated census of South East England’s parakeet population size and growth, and investigate any evidence of ecological impacts to help inform policy makers making decisions on mitigation strategies for the rose-ringed parakeet. This has been achieved through using roost counts to regularly survey the population over three years and by carrying out two garden feeding experiments to look at effects of parakeet presence on bird feeding behaviour and on competition for food. I show that the rose-ringed parakeet population is well established in the UK, with over 30,000 individuals, has undergone rapid growth since 1996 but that the core London population appears to have reached capacity. I also show evidence of competition for food between parakeets and native birds, causing negative impacts on native bird foraging behaviour and resulting in a reduction in garden bird species accessing food. The overall findings of this research are that parakeets have the potential to reach high numbers in urban areas and that they do compete for food with native birds, but as yet there is no evidence for population level effects on native species. This adds to the knowledge of ecological impacts of the rose-ringed parakeet and provides further insight into the behavioural impacts that non-native species can have on native wildlife. I discuss the implications of these findings for future management and policy.
