Effects of density-dependent dispersal behaviours on the speed and spatial patterns of range expansion in predator-prey metapopulations
Ramanantoanina, A; Hui, C; Ouhinou, A (2011)Dispersal can strongly affect the spatiotemporal dynamics of a species (its spread, spatial distribution and persistence). We investigated how two dispersal behaviours, namely prey evasion (PE) and predator pursuit (PP), ... -
Effects of plant availability and habitat size on the coexistence of two competing parasitoids in a tri-trophic food web of canola, diamondback moth and parasitic wasps
Soufbaf, M; Fathipour, Y; Hui, C; Karimzadeh, J (2012)Using experiments and spatial modeling, we here show the conditions for two competing parasitoids to coexist under two levels of plant availability in a tri-trophic food web of canola, diamondback moth (Plutella xylostella) ... -
A first record of biological soil crusts in the Cape Floristic Region
Mager, DM; Hui, C (2012)To date, the biological soil crusts (BSCs) of southern Africa are thought to be dominated mainly by cyanobacteria, with the exception of the lichen fields of the Namib Desert. Because soil microorganisms can physically ... -
Flexible dispersal strategies in native and non-native ranges: environmental quality and the ‘good-stay, bad-disperse’ rule
Hui, C; Roura-Pascual, N; Brotons, L; Robinson, RA; Evans, KL (2012)Dispersal strategies are one of the most important determinants of range dynamics and a surrogate for invasiveness. We tested three inter-related hypotheses derived from demographic and ecological models: (H1) short-distance ... -
From the inverse density-area relationship to the minimum patch size of a host-parasitoid system
Zhao, ZH; He, DH; Hui, C (2012)The minimum amount of suitable habitat (MASH) is an important concept in conservation biological control. Two methods for estimating the MASH have been proposed by McCoy and Mushinsky based on an inverse density–area ... -
Importance of primary metabolites in canola in mediating interactions between a specialist leaf-feeding insect and its specialist solitary endoparasitoid
Soufbaf, M; Fathipour, Y; Zalucki, MP; Hui, C (2012)The role of primary plant chemistry on trophic interactions is not well studied. We examined the effect of primary plant metabolites, focusing on nitrogen, on several biological indices of second and third trophic level ... -
Invasiveness in introduced Australian acacias: the role of species traits and genome size
Gallapher, RV; Leishman, MR; Miller, JT; Hui, C; Richardson, DM; Suda, J; Trávníček, P (2011)Aim To assess associations between invasiveness, genome size and species traits in Australian Acacia species introduced outside their native range. Location Global. Methods Holoploid genome size was determined by flow ... -
Macroecology meets invasion ecology: linking the native distributions of Australian acacias to invasiveness
Hui, C; Richardson, DM; Robertson, MP; Wilson, JRU; Yates, CJ (2011)Aim Species’ native ranges reflect the net outcome of interactions between lifehistory strategies and biotic and abiotic influences over evolutionary time-scales. Differences in native ranges might be indicative both of ... -
Organism-induced habitat restoration leads to bi-stability in metapopulations
Zhang, F; Tao, Y; Hui, C (2012)Following Levins’ patch occupancy model, we presented a differential-equation model, in which both the metapopulation dynamics and the dynamics of the fraction of suitable patches in the habitat are characterized. Habitat ... -
Scale effect and bimodality in the frequency distribution of species occupancy
Hui, C (2012)Community patterns in species-by-site matrices provide valuable clues for inferring ecological processes at work. One such pattern is the occupancy frequency distribution (OFD) depicting the frequency distribution of row ...
