Potential impacts of future land use and climate change on the Red List status of the Proteaceae in the Cape Floristic Region, South Africa
(BLACKWELL PUBLISHING, 2005)Using spatial predictions of future threats to biodiversity, we assessed for the first time the relative potential impacts of future land use and climate change on the threat status of plant species. We thus estimated how ... -
Species richness of alien plants in South Africa: environmental correlates and the relationship with indigenous plant species richness
(2005)This study explores the correlates of alien plant species richness in South Africa at the scale of quarter-degree squares (QDS; ≈ 25 x 27 km; 675km2). We considered all alien plant species for which we had records and a ... -
Niche-based modelling as a tool for predicting the risk of alien plant invasions at a global scale
(BLACKWELL PUBLISHING, 2005-12)Predicting the probability of successful establishment of plant species by matching climatic variables has considerable potential for incorporation in early warning systems for the management of biological invasions. We ... -
A spatially explicit approach to estimating species occupancy and spatial correlation
(BLACKWELL PUBLISHING, 2006-01)1. Understanding and predicting the form of species distributions, or occupancy patterns, is fundamental to macroecology and is dependent on the identification of scaling relationships that underlie the patterns observed. ... -
Interactions between environment, species traits, and human uses describe patterns of plant invasions
(ECOLOGICAL SOC AMER, 2006-07)Although invasive alien species (IAS) are a major threat to biodiversity, human health, and economy, our understanding of the factors controlling their distribution and abundance is limited. Here, we determine how environmental ... -
Modeling species distributions by breaking the assumption of self-similarity
(2007)Species distributions are commonly measured as the number of sites, or geographic grid cells occupied. These data may then be used to model species distributions and to examine patterns in both intraspecific and interspecific ... -
Capturing the ‘droopy tail’ in the occupancy-abundance relationship
(2007)The intraspecific occupancy–abundance relationship is a widely used descriptor of species distributions, with potential value to conservation and pest management for predicting species abundance from occurrence data. Six ... -
A self-similarity model for occupancy frequency distribution
(2007)The shapes of interspecific range-size distributions at scales finer than the geographic range are highly variable. However, no numerical model has been developed as a basis for understanding this variation. Using ... -
Spatial patterns of prisoner’s dilemma game in metapopulations
(Society for Mathematical Biology, 2007)Because to defect is the evolutionary stable strategy in the prisoner’s dilemma game (PDG), understanding the mechanism generating and maintaining cooperation in PDG, i.e. the paradox of cooperation, has intrinsic significance ... -
Modelling the winter distribution of a rare and endangered migrant, the Aquatic Warbler Acrocephalus paludicola
(British Ornithologists’ Union, 2007)The Aquatic Warbler Acrocephalus paludicola is one of the most threatened Western Palearctic passerine species, classified as globally Vulnerable. With its breeding grounds relatively secure, a clear need remains for the ... -
Home away from home - objective mapping of high-risk source areas for plant introductions
(BLACKWELL PUBLISHING, 2007-05)Prevention is the best way to slow the escalation of problems associated with biological invasions. Screening of potential introductions is widely applied for assessing the risk of species becoming invasive. Despite advances ... -
Spatiotemporal dynamics of the epidemic transmission in a predator-prey system
(2008)Epidemic transmission is one of the critical density-dependent mechanisms that affect species viability and dynamics. In a predator-prey system, epidemic transmission can strongly affect the success probability of hunting, ... -
The effect of migration on the spatial structure of intraguild predation in metapopulations
(2008)We consider the effects of migration on intraguild predation (IGP) via lattice models and pair approximation. The following results can be found: there exists asymmetry between two consumers’ migration effects on the ... -
Does the self-similar species distribution model lead to unrealistic predictions?
(2008)J. Harte et al. demonstrated that the power law form of the species–area relationship may be derived from a bisected, self-similar landscape and a community-level probability rule. Harte’s self-similarity model has been ... -
Crossing the borders of spatial analysis and modelling: A rethink
(Nova Science Publishers, 2008)Understanding the mechanisms behind the spatial patterns of species distributions is one of the major focuses in theoretical ecology. Spatial modelling techniques such as lattice models and cellular automata bring numerous ... -
On species-area and species accumulation curves: A comment on Chong and Stohlgren’s index
(2008)Chong and Stohlgren [Chong, G.W., Stohlgren, T.J., 2007. Species–area curves indicate the importance of habitats’ contributions to regional biodiversity. Ecol. Indic. 7, 387–395] presented a combined ranking index to ... -
Consensual predictions of potential distributional areas for invasive species: a case study of Argentine ants in the Iberian Peninsula
(Springer Science+Business Media B.V., 2009)Invasive species are known to influence the structure and function of invaded ecological communities, and preventive measures appear to be the most efficient means of controlling these effects. However, management of ... -
A Bayesian Solution to the Modifiable Areal Unit Problem
(Springer-Verlag, Berlin, 2009)The Modifiable Areal Unit Problem (MAUP) prevails in the analysis of spatially aggregated data and influences pattern recognition. It describes the sensitivity of the measurement of spatial phenomena to the size (the ... -
From introduction to equilibrium: reconstructing the invasive pathways of the Argentine ant in a Mediterranean region
(2009)Determining the geographical range of invasive species is an important component of formulating effective management strategies. In the absence of detailed distributional data, species distribution models can provide ...
