Turing instability in pioneer/climax species interactions
Mathematical Biosciences, 2005Systems of pioneer and climax species are used to model interactions of species whose reproductive capacity is sensitive to population density in their shared ecosystem. Intraspecies interaction coefficients can be adjusted so that spatially homogeneous solutions are stable to small perturbations.

Plant biomorphology and seed germination in pioneer species of Kamchatka volcanoes
Biology Bulletin, 2008Biomorphology, metric characters, and seed germination have been studied in 17 pioneer plant species overgrowing friable erupted materials in the Kamchatka Peninsula. The diversity of pathways of adaptation to stressful growing conditions is discussed. The response of seeds to ultralow temperature (−196°C) has been analyzed to evaluate the possibility ...

Natural variation in innate immunity of a pioneer species
Current Opinion in Plant Biology, 2007By 2010, we will have detailed knowledge about the genome of Arabidopsis thaliana from a Linnean-like effort by an international research community to identify nearly all of the genes in the species and to classify the products that these genes encode according to a primary function in a generic plant cell.

Identifying pioneer bacterial species responsible for biofouling membrane bioreactors
Environmental Microbiology, 2006Summary More effective control of membrane biofouling in membrane bioreactors (MBRs) lies in the fundamental understanding of the pioneer microorganisms responsible for surface colonization that leads to biofilm formation. In this study, the composition of the planktonic and sessile microbial communities inhabiting four laboratory ...

Species identity influences secondary removal of seeds of Neotropical pioneer tree species
Plant Ecology, 2017Primary dispersal agents move seeds from the maternal plant to the soil surface where they are often moved again by secondary dispersal agents. However, the extent to which different species in the same location experience secondary dispersal is often unknown despite the importance of this mechanism for determining recruitment opportunities and ...

Role of dispersal in the recruitment limitation of neotropical pioneer species
Journal of Ecology, 2002Summary We examined the importance of seed dispersal in predicting the pioneer seedling composition in recent gaps in a forest plot on Barro Colorado Island (BCI), Panama. We characterize seed dispersal for 13 taxa from seed rain data collected over 13 years in 200 mesh traps, and for an additional species from germination from soil samples collected ...

Hopf bifurcation in pioneer-climax competing species models
Mathematical Biosciences, 1996Two-dimensional pioneer-climax models of competing species differential equations are introduced and examined. The per capita growth rates are functions of weighted densities of the individual species. Constant rate forcing is added representing stocking or harvesting. The ensuring stability properties of interior equilibria are studied.
