We formalize the establishment process for a sexual, semelparous organism through the use of hierarchical probability modeling from parameters of survival, probability of being female, probability of being fertilized, and expected fecundity.We show how to calculate the expected per capita growth...

Abstract: The lowering of the water table resulting from peatland drainage may dramatically alter C and N cycling in peatland ecosystems, which contain one-third of the total terrestrial C. In this study, tree annual ring width and C (delta C-13) and N (delta N-15) isotope ratios in soil and...

Effect of fluctuating temperature and propagule flow on invasibility of global marine habitats and species distribution
DownloadFall 2013
Invasive colonizers propagated through human-mediated vectors are bio-homogenizing the world’s oceans and impacting the ecological structures and functions. Where do they come from, and where do they go? What bio-physical mechanisms drive them to do what they do? Can we control the human-mediated...

Resiliency of boreal forest tree species on a reclaimed oil sands mine and natural forest stands in northeastern Alberta
DownloadSpring 2019
Disturbances in the boreal forest are common, so the species that comprise these forests must be resilient to them. This research examines the resiliency, here defined as the regeneration of boreal tree species following disturbance on both reclaimed and natural sites. The suckering response of...

Temperature-dependent Allee effects in a stage-structured model for Bythotrephes establishment
Download2011-01-01
Young, J. D., Yan, N. D., Lewis, Mark A., Wittmann, M. J.
Whether the invasive freshwater cladoceran Bythotrephes longimanus can establish after introduction into a water body depends on several biotic and abiotic factors. Among these, water temperature is important because both development rates and mode of reproduction (parthenogenetic or sexual) in...

The process of nonindigenous species (NIS) arrival has received limited theoretical consideration despite importance in predicting and preventing the establishment of NIS. We formulate a mechanistically based hierarchical model of NIS arrival and demonstrate simplifications leading to a marginal...
