description: We present a novel bio-inspired and dynamic coding scheme for static images. Our coder aims at reproducing the main steps of the visual stimulus processing in the mammalian retina taking into account its time behavior. The main novelty of this work is to show how to exploit the time behavior of the retina cells to ensure, in a simple way, scalability and bit allocation. To do so, our main source of inspiration will be the biologically plausible retina model called Virtual Retina. Following a similar structure, our model has two stages. The first stage is an image transform which is performed by the outer layers in the retina. Here it is modelled by filtering the image with a bank of difference of Gaussians with time-delays. The second stage is a time-dependent analog-to-digital conversion which is performed by the inner layers in the retina. Thanks to its conception, our coder enables scalability and bit allocation across time. Also, our decoded images do not show annoying artefacts such as ringing and block effects. As a whole, this article shows how to capture the main properties of a biological system, here the retina, in order to design a new efficient coder.

description: The radii of nucleon distribution and neutron skin in nuclei beyond the β-stability line are studied within the extended Thomas-Fermi approximation. We show that the growth of neutron skin in unstable nuclei does not obey the saturation condition because of the neutron coat. The neutron coat indicates the possibility of giant neutron halo which is growing with moving away from the beta stability line. We demonstrate the presence of strong shell oscillations in the charge radius R_C and the relation of R_C to the isospin shift of neutron-proton chemical potentials Δλ=λ_n-λ_p for nuclei beyond the beta-stability line at fixed value of mass number A.

description: We give a sufficient condition for the abstract basin of attraction of a sequence of holomorphic self-maps of balls in \mathbb{C}^{d} to be biholomorphic to \mathbb{C}^{d}. As a consequence, we get a sufficient condition for the stable manifold of a point in a compact hyperbolic invariant subset of a complex manifold to be biholomorphic to a complex Euclidean space. Our result immediately implies previous theorems obtained by Jonsson-Varolin and by Peters; in particular, we prove (without using Oseledec's theory) that the stable manifold of any point where the negative Lyapunov exponents are well-defined is biholomorphic to a complex Euclidean space. Our approach is based on the solution of a linear control problem in spaces of subexponential sequences, and on careful estimates of the norm of hte conjugacy operator by a lower triangular matrix on the space of \textit{k}-homogeneous polynomial endomorphisms of \mathbb{C}^{d}.

Effects of postharvest deficit irrigation on sweet cherry (Prunus avium) in five Okanagan orchards
Creators: name: Bevandick, Kirsten Irene
Publisher: name: University of British Columbia
Year: 2022

description: The timing and availability of water is changing for Okanagan cherry producers. Reducing irrigation after harvest by 25 % is a feasible method to conserve water in Okanagan cherry orchards; however, the effects of further reductions after harvest are unknown. To answer this question, the effects of postharvest deficit irrigation (PDI) in five Okanagan sweet cherry orchards (Prunus avium) at varying elevations and latitudes were assessed. Postharvest deficit irrigation was imposed, along with a full irrigation (FI) control, by reducing the amount of irrigation normally applied to trees after harvest by 25 %, and 50 %, in each of the five studied orchards. The aims of this study were to: (1) determine how PDI affects fruit yield, quality before and after storage; (2) assess the impacts of PDI on stem water potential, leaf gas exchange, water use efficiency (WUE), vegetative growth, and soil gas exchange; and (3) complete a cost benefit analysis (CBA) of adopting PDI in Okanagan cherry orchards. When all of the data were combined from five study sites, and two years, 50 % PDI had no effects on fruit quality, yield, stem water potential, leaf gas exchange, vegetative growth, or soil gas exchange. Growers may have irrigated above field capacity; therefore, reducing irrigation did not lead to increased water stress. Given PDI had no negative effects on fruit quality or yield, there were little to no costs associated with adopting PDI in Okanagan orchards. Adopting PDI resulted in an estimated net present value of $5.80 m⁻³ over 20 years. Although PDI did not generally induce water stress, trees that were water stressed had significant decreases in photosynthetic rates (An), stomatal conductance (gs), and transpiration rates (E), and significant increases in WUEintrinsic (An/gs). Stem water potential can likely drop to -1.88 MPa for a short period of time, or -1.32 MPa over the entire postharvest period without causing lasting damage to vascular tissues. This study offers important insight into the feasibility of adopting PDI in Okanagan cherry orchards. The CBA also provides one of the first assessments of the value of adopting water conservation practices in the Okanagan Valley.
The Atmospheric Chemistry of GJ 1214b: Photochemistry and Clouds

description: Recent observations of the transiting super-Earth GJ 1214b reveal that its atmosphere may be hydrogen-rich or water-rich in nature, with clouds or hazes potentially affecting its transmission spectrum in the optical and very-near-IR. Here we further examine the possibility that GJ 1214b does indeed possess a hydrogen-dominated atmosphere, which is the hypothesis that is favored by models of the bulk composition of the planet. We study the effects of non-equilibrium chemistry (photochemistry, thermal chemistry, and mixing) on the planet's transmission spectrum. We furthermore examine the possibility that clouds could play a significant role in attenuating GJ 1214b's transmission spectrum at short wavelengths. We find that non-equilibrium chemistry can have a large effect on the overall chemical composition of GJ 1214b's atmosphere, however these changes mostly take place above the height in the atmosphere that is probed by transmission spectroscopy. The effects of non-equilibrium chemistry on GJ 1214b's transmission spectrum are therefore minimal, with the largest effects taking place if the planet's atmosphere has super-solar metallicity and a low rate of vertical mixing. Interestingly, we find that the best fit to the observations of GJ 1214b's atmosphere in transmission occur if the planet's atmosphere is deficient in CH4, and possesses a cloud layer at a pressure of ~200 mbar. This is consistent with a picture of efficient methane photolysis, accompanied by formation of organic haze that obscures the lower atmosphere of GJ 1214b at optical wavelengths. However, for methane to be absent from GJ 1214b's transmission spectrum, UV photolysis of this molecule must be efficient at pressures of greater than ~1 mbar, whereas we find that methane only photolyzes to pressures less than 0.1 mbar, even under the most optimistic assumptions.

description: The baby Skyrme model is studied with a novel choice of potential, $V=1/2 ϕ_3^2$. This "easy plane" potential vanishes at the equator of the target two-sphere. Hence, in contrast to previously studied cases, the boundary value of the field breaks the residual SO(2) internal symmetry of the model. Consequently, even the unit charge skyrmion has only discrete symmetry and consists of a bound state of two half lumps. A model of long-range inter-skyrmion forces is developed wherein a unit skyrmion is pictured as a single scalar dipole inducing a massless scalar field tangential to the vacuum manifold. This model has the interesting feature that the two-skyrmion interaction energy depends only on the average orientation of the dipoles relative to the line joining them. Its qualitative predictions are confirmed by numerical simulations. Global energy minimizers of charges B=1,...,14,18,32 are found numerically. Up to charge B=6, the minimizers have 2B half lumps positioned at the vertices of a regular 2B-gon. For charges B >= 7, rectangular or distorted rectangular arrays of 2B half lumps are preferred, as close to square as possible.

description: Gas sensors allow the monitoring of the chemical environment of humans, which is often crucial for their
wellbeing or even survival. Miniaturization, reversibility, and selectivity are some of the key challenges for
serial use of chemical sensors. This tutorial review describes critical aspects when using nanomaterials as
sensing substrates for the application in chemiresistive gas sensors. Graphene has been shown to be
a promising candidate, as it allows gas sensors to be operated at room temperature, possibly saving large
amounts of energy. In this review, an overview is given on the general mechanisms for gas-sensitive
semiconducting materials and the implications of doping and functionalization on the sensing
parameters of chemiresistive devices. It shows in detail how different challenges, like sensitivity, response
time, reversibility and selectivity have been approached by material development and operation modes.
In addition, perspectives from the area of data analysis and intelligent algorithms are presented, which
can further enhance these sensors' usability in the field.

description: We search the Fermi-LAT photon database for an extended gamma-ray emission which could be associated with any of the 581 previously detected gamma-ray bursts (GRBs) visible to the Fermi-LAT. For this purpose we compare the number of photons with energies E > 100 MeV and E > 1 GeV which arrived in the first 1500 seconds after the burst from the same region, to the expected background. We require that the expected number of false detections does not exceed 0.05 for the entire search and find the high-energy emission in 19 bursts, four of which (GRB 081009, GRB 090720B, GRB 100911 and GRB 100728A) were previously unreported. The first three are detected at energies above 100 MeV, while the last one shows a statistically significant signal only above 1 GeV.

description: With the advent of the LHC, it is important to devise clear tests for Physics Beyond the Standard Model. Such physics could manifest itself in the form of new charged bosons, whose presence is most naturally occurring in left-right symmetric models (LRSM). We analyze the single $W_R$ boson production in an asymmetric left-right model, where the left and right quark mixing matrices are not constrained to be equal. We investigate the cross sections as well as branching ratios of $W_R$ bosons at the LHC, including constraints from low energy phenomenology. We then look for most likely signals in $pp \to W_R\ t \to t ~(dijet)$ production. Including the background, we find that LHC could show significant signals for the new charged bosons. We compare our results throughout with the manifest left-right symmetric model and comment on similarities and differences.

ABDURAKHMAN JAMI AND ALISHER NAVOI'S ANALYSIS OF THE EPICS "LAYLI AND MAJNUN"
Creators: name: Avezova, Aziza
Publisher: name: Zenodo
Year: 2023

description: Layli and Majnun[1] are popular folklore and written literary monuments among the peoples of the Near and Middle East. The first buds of the epic appeared in the second half of the 7th century. According to some sources, the heroes of the saga are historical figures. They mention that Majnun was a young man from the tribe of Bani Amir, whose real name was Qays bin Mulawwah or Qays bin Muad. He loved his fellow tribesman named Kais Laili and wrote sad poems about his love and the sufferings of hijran. Such information is provided, among other things, in the works of Ibn Qutayba (889) "Kitab ush-she'er wa shuaro" ("Book about poetry and poets"), "Kitab ul-Aghoni" ("Book of Songs") by Abul Faraj al-Isfahani. But other sources deny this information. For example, Arab scholar Avon ibn Hakim al-Qalbi (764) and Arab historian Hisham al-Qalbi (819) argue that Majnun is not a historical figure. As early as the second half of the 7th century, many sad poems appeared in Arabic poetry under the pseudonym Majnun.

description: Given a closed Riemannian manifold (M, g), there is a partition Σ_i of its tangent bundle TM called the focal decomposition. The sets Σ_i are closely associated to focusing of geodesics of (M, g), i.e. to the situation where there are exactly i geodesic arcs of the same length joining points p and q in M. In this note, we study the topological structure of the focal decomposition of a closed Riemannian manifold and its relation with the metric structure of the manifold. Our main result is that the flat n-tori are focally rigid, in the sense that if two flat tori are focally equivalent, then the tori are isometric up to rescaling.

description: Charmed mesons may be produced when a primary cosmic ray or the leading hadron in an air shower collide with an atmospheric nucleon. At energies \ge 10^8 GeV their decay length becomes larger than 10 km, which implies that they tend to interact in the air instead of decaying. We study the collisions of long-lived charmed hadrons in the atmosphere. We show that (Λ_c,D)-proton diffractive processes and partonic collisions of any q^2 where the charm quark is an spectator have lower inelasticity than (p,π)-proton collisions. In particular, we find that a D meson deposits in each interaction just around 55% of the energy deposited by a pion. On the other hand, collisions involving the valence c quark (its annihilation with a sea cbar quark in the target or c-quark exchange in the t channel) may deposit most of D meson energy, but their frequency is low (below 0.1% of inelastic interactions). As a consequence, very energetic charmed hadrons may keep a significant fraction of their initial energy after several hadronic interactions, reaching much deeper in the atmosphere than pions or protons of similar energy.

description: A fully parallel version of the contact dynamics (CD) method is presented in this paper. For large enough systems, 100% efficiency has been demonstrated for up to 256 processors using a hierarchical domain decomposition with dynamic load balancing. The iterative scheme to calculate the contact forces is left domain-wise sequential, with data exchange after each iteration step, which ensures its stability. The number of additional iterations required for convergence by the partially parallel updates at the domain boundaries becomes negligible with increasing number of particles, which allows for an effective parallelization. Compared to the sequential implementation, we found no influence of the parallelization on simulation results.

Modeling of chip formation mechanism in machining carbon fiber reinforced polymer
Creators: name: Song, Chunlei
Publisher: name: University of British Columbia
Year: 2022

description: Carbon fiber reinforced polymer (CFRP) composites possess high specific strength, high specific elastic modulus, and high energy absorption ability, which make them competitive in advanced industrial applications such as aerospace, automotive, and construction. To achieve the dimension and tolerance requirements of the CFRP components, cutting operations such as milling and drilling are necessary. A mechanics model of the chip formation is developed to investigate the buckling failure mode, which occurs at 0° fiber orientation, by dividing the chip formation into shearing and buckling processes. The chip length increases owing to the shear failure in the interface layer until the Euler buckling or micro buckling failure is activated. The nonlinear relationship between the cutting forces and uncut material is modeled and validated by experiments. A generalized mechanics model is proposed to predict the chip formation mode (fiber and matrix failure modes), chip formation angle, and cutting forces in the entire fiber orientation range of [0°, 180°] for UD CFRP. For each fiber orientation, the stresses on the chip formation plane needed to activate the relevant chip formation mode, including fiber tension, fiber compression, matrix tension, and matrix compression, are determined. The chip formation plane which requires the minimum cutting energy is found, and the corresponding failure stresses and cutting forces are predicted with experimental validation. To further analyze the damage states for fiber and matrix material during the chip formation, a frictional-damage mechanics model is developed. It is found that the friction in the damaged area under transverse compression can provide additional stress on the fracture plane. This friction is able to increase the shear stress on the fracture plane after the failure is initiated, and then influence the direction of the fracture plane in uncut material. For the MD CFRP, it is found that the plies of different fiber orientation angles converge in the cutting process. An analytical model is proposed to analyze the variation of chip formation mode for each ply in the orthogonal cutting of MD CFRP. By using the minimum energy principle for all plies, the variation chip formation mode due to the interlaminar bonding effect is predicted.

We consider the photon energies $\hbarΩ$ that significantly exceed the height of the potential barrier, as is the case in the recent experiments with graphene-based photodetectors. The photocurrent comes from the resonant absorption of photons by electrons and decreases with increasing ratio $\hbarΩ/U_0$. It is weakly affected by the background gate voltage and depends on the light polarization as $\propto\sin^2γ$, $γ$ being the angle between the potential and the polarization plane.

description: The Data-Intensive Farm Management Project runs large-scale, on-farm randomized field trials to estimate relationships among crop yields, managed input application rates, field characteristics, and weather variables. DIFM is developing cloud-based farm management decision tools, that help farmers make management decisions on their own farm fields, based on data generated on those same fields. In 2019, DIFM will run approximately seventy trials in ten U.S. states, Argentina, Brazil, and Colombia. DIFM is developing software that will allow it to “scale up” its data management, processing, and analysis activities, and provide a farmer-consultant decision tool that will allow the practical implications of the data analysis to positively affect the efficiency of farmers’ input management decision. DIFM is interested in exploring possibilities of working with other groups to develop a cloud-based research cyber-infrastructure that will aid researchers worldwide who conduct run on-farm agronomic research.

description: Spermatozoa are highly specialized cells with unique morphology. In addition, spermatozoa lose a considerable amount of cytoplasm during spermiogenesis, when they also compact their DNA, resulting in a transcriptionally quiescent cell. Throughout the male reproductive tract, sperm will acquire proteins that enable them to interact with the female reproductive tract. After ejaculation, proteins undergo post-translational modifications for sperm to capacitate, hyperactivate, and fertilize the oocyte. Many proteins have been identified as predictors of male infertility and also investigated in diseases that compromise reproductive potential. In this review, we proposed to summarize the recent findings about the sperm proteome and how they affect sperm structure, function, and fertility. A literature search was performed using PubMed and Google Scholar databases within the past 5 years until August 2022. Sperm function depends on protein abundance, conformation, and PTMs; understanding the sperm proteome may help to identify pathways essential to fertility, even making it possible to unravel the mechanisms involved in idiopathic infertility. In addition, proteomics evaluation offers knowledge regarding alterations that compromise the male reproductive potential.

description: We discuss a scheme for a full superdense coding of entangled photon states employing only linear-optics elements. By using the mixed basis consisting of four states that are unambiguously distinguishable by a standard and polarizing beam splitters we can deterministically transfer four messages by manipulating just one of the two entangled photons. The sender achieves the determinism of the transfer either by giving up the control over 50% of sent messages (although known to her) or by discarding 33% of incoming photons.

description: To determine the relative distances and peculiar velocities of 140 groups and clusters of galaxies at low redshifts ($z$ < 0.12), we used the fundamental plane (FP) of early-type galaxies (from the Sloan Digital Sky Survey (SDSS) data). We constructed the Hubble diagram for the relative distances of galaxy groups/clusters versus their radial velocities in the cosmic microwave background (CMB) reference frame in the flat $Λ$ cold dark matter ($Λ$CDM) model ($Ω_m=0.3$, $H_0=70$~km~s$^{-1}$ Mpc$^{-1}$). We have found that the standard logarithmic deviation for groups and clusters of galaxies on the Hubble diagram (minus peculiar velocities) is $\pm0.0173$ ($N$ = 140), which corresponds to a deviation of $70\pm2.8$~km~s$^{-1}$ Mpc$^{-1}$ in the Hubble constant. For a sample of galaxy systems ($N$ = 63), the X-ray luminosity of which is in an interval of (0.151--4)~$\times 10^{44}$~erg/s, this quantity turned out to be $70\pm2.1$~km~s$^{-1}$ Mpc$^{-1}$. The root-mean-square deviations of peculiar velocities with quadratic accounting for errors are $^{1/2}$ = $714\pm7$~km/s and $600\pm7$~km/s, respectively. For five large superclusters of galaxies from the SDSS region, the average peculiar velocity relaive to the CMB reference frame is $+240\pm250$~km/s. We detected no outflow of galaxy systems from the void (Giant Void, $α\approx 13^h, δ\approx 40^\circ, z \approx 0.107$) formed by groups and clusters of galaxies.

description: We study the dynamical decoupling of multiqubit states from environment. For a system of m qubits, the nested Uhrig dynamical decoupling (NUDD) sequence can efficiently suppress generic decoherence induced by system-environment interaction to order N using (N+1)^2m pulses. We prove that the NUDD sequence is universal, i.e., it can restore the coherence of m-qubit quantum system independent of the details of system-environment interaction. We also construct a general mapping between dynamical decoupling problems and discrete quantum walks in certain functional spaces.

description: In order to investigate the phenomenological implications of warped spaces in more than five dimensions, we consider a $4+1+δ$ dimensional extension to the Randall and Sundrum model in which the space is warped with respect to a single direction by the presence of an anisotropic bulk cosmological constant. The Einstein equations are solved, giving rise to a range of possible spaces in which the $δ$ additional spaces are warped. Here we consider models in which the gauge fields are free to propagate into such spaces. After carrying out the Kaluza Klein (KK) decomposition of such fields it is found that the KK mass spectrum changes significantly depending on how the $δ$ additional dimensions are warped. We proceed to compute the lower bound on the KK mass scale from electroweak observables for models with a bulk $SU(2)\times U(1)$ gauge symmetry and models with a bulk $SU(2)_R\times SU(2)_L\times U(1)$ gauge symmetry. It is found that in both cases the most favourable bounds are approximately $M_{KK}\gtrsim 2$ TeV, corresponding to a mass of the first gauge boson excitation of about 4-6 TeV. Hence additional warped dimensions offer a new way of reducing the constraints on the KK scale.

description: We study decoherence in the quantum walk on the xy-plane. We generalize the method of decoherent coin quantum walk, introduced by [T.A. Brun, et.al, Phys.Rev.A 67 (2003) 032304],which could be applicable to all sorts of decoherence in two dimensional quantum walks, irrespective of the unitary transformation governing the walk. As an application we study decoherence in the presence of broken line noise in which the quantum walk is governed by the two-dimensional Hadamard operator.

description: The Crab Nebula is the only hard X-ray source in the sky that is both bright enough and steady enough to be easily used as a standard candle. As a result, it has been used as a normalization standard by most X-ray/gamma ray telescopes. Although small-scale variations in the nebula are well-known, since the start of science operations of the Fermi Gamma-ray Burst Monitor (GBM) in August 2008, a ~ 7% (70 mcrab) decline has been observed in the overall Crab Nebula flux in the 15 - 50 keV band, measured with the Earth occultation technique. This decline is independently confirmed with three other instruments: the Swift Burst Alert Telescope (Swift/BAT), the Rossi X-ray Timing Explorer Proportional Counter Array (RXTE/PCA), and the INTErnational Gamma-Ray Astrophysics Laboratory Imager on Board INTEGRAL (IBIS). A similar decline is also observed in the ~3 - 15 keV data from the RXTE/PCA and INTEGRAL Joint European Monitor (JEM-X) and in the 50 - 100 keV band with GBM and INTEGRAL/IBIS. Observations from 100 to 500 keV with GBM suggest that the decline may be larger at higher energies. The pulsed flux measured with RXTE/PCA since 1999 is consistent with the pulsar spin-down, indicating that the observed changes are nebular. Correlated variations in the Crab Nebula flux on a ~3 year timescale are also seen independently with the PCA, BAT, and IBIS from 2005 to 2008, with a flux minimum in April 2007. As of August 2010, the current flux has declined below the 2007 minimum.

description: Ever since Werner Heisenberg's 1927 paper on uncertainty, there has been considerable hesitancy in simultaneously considering positions and momenta in quantum contexts, since these are incompatible observables. But this persistent discomfort with addressing positions and momenta jointly in the quantum world is not really warranted, as was first fully appreciated by Hilbrand Groenewold and José Moyal in the 1940s. While the formalism for quantum mechanics in phase space was wholly cast at that time, it was not completely understood nor widely known --- much less generally accepted --- until the late 20th century.

Time-variability in the Interstellar Boundary Conditions of the Heliosphere: Effect of the Solar Journey on the Galactic Cosmic Ray Flux at Earth

description: During the solar journey through galactic space, variations in the physical properties of the surrounding interstellar medium (ISM) modify the heliosphere and modulate the flux of galactic cosmic rays (GCR) at the surface of the Earth, with consequences for the terrestrial record of cosmogenic radionuclides. One phenomenon that needs studying is the effect on cosmogenic isotope production of changing anomalous cosmic ray fluxes at Earth due to variable interstellar ionizations. The possible range of interstellar ram pressures and ionization levels in the low density solar environment generate dramatically different possible heliosphere configurations, with a wide range of particle fluxes of interstellar neutrals, their secondary products, and GCRs arriving at Earth. Simple models of the distribution and densities of ISM in the downwind direction give cloud transition timescales that can be directly compared with cosmogenic radionuclide geologic records. Both the interstellar data and cosmogenic radionuclide data are consistent with cloud transitions during the Holocene, with large and assumption-dependent uncertainties. The geomagnetic timeline derived from cosmic ray fluxes at Earth may require adjustment to account for the disappearance of anomalous cosmic rays when the Sun is immersed in ionized gas.

description: We describe a nonlinear interaction between charge currents and spin currents which arises from the energy dependence of the conductivity. This allows nonmagnetic contacts to be used for measuring and controlling spin signals. We choose graphene as a model system to study these effects and predict its magnitudes in nonlocal spin valve devices. The ambipolar behavior of graphene is used to demonstrate amplification of spin accumulation in p-n junctions by applying a charge current through nonmagnetic contacts.

Outcomes of stream invertebrate mesopredator interactions to benthic food webs and ecosystem functions
Creators: name: Tikka, Kelsey
Publisher: name: University of British Columbia

description: Within the predator guild of ecological communities are smaller-bodied mesopredators that have the ability to directly impact community structure and indirectly alter ecosystem processes. Interactions between predators can result in combined predator outcomes to their prey, termed Multiple Predator Effects (MPEs), that can be additive, antagonistic, or synergistic with the strength and direction contingent on predator identity and guild diversity. In streams on the west coast of North America, there are two co-occurring predatory stonefly larvae, Calineuria californica and Hesperoperla pacifica, both of which can cause direct depletion of the prey community which can cascade to indirectly alter leaf litter decomposition and periphyton standing stock. My objective was to quantify the role and outcome of intra- and interspecific interactions of C. californica and H. pacifica on stream food webs. I manipulated stonefly larvae identity and density, as well as richness of the predator guild, then compared larval growth and survival, prey community composition, and measures of basal resources to determine the MPE outcomes. I hypothesized that due to the high degree of niche overlap that competition would lead to antagonistic MPEs. I also hypothesized that increasing density and the presence of the more aggressive H. pacifica would lead to higher competition and stronger antagonistic MPEs. I found that stonefly larvae presence caused a 46% reduction in the prey community, and that increasing biomass of either species significantly caused this decline. For interspecific and intraspecific C. californica pairings there was density-dependent competition resulting in a switch from additive to antagonistic MPEs, while intraspecific H. pacifica pairings had antagonistic MPEs at all densities. I also found that the mechanism of predator impacts varied between the two species, with H. pacifica decreasing the prey community through consumption and C. californica through non-consumptive behavioural modification of prey. However, the effects to the prey community did not cascade to impact the basal resources. My results demonstrate that the type and strength of predator interactions may be contingent on the composition of the predator guild and may result in unexpected, non-linear outcomes to the community.
