Establishing vegetation on a constructed fen in a post-mined landscape in Alberta’s oil sands region: A four-year evaluation after species introduction

Ecological Engineering: The Journal of Ecotechnology, 2019
Oil sands mining in Alberta has disturbed large areas of peatland, the dominant regional ecosystem type, and no formal strategies exist to reconstruct the landscape.

Reducing the Risks of Nonindigenous Species Introductions

BioScience, 1995
A though plants and animals have always spread across the globe, expanding their ranges and invading new territories, human civilization has accelerated these biological invasions to an extraordinary degree. Nonindigenous species represent a major threat to the integrity of natural systems, because they can alter nutrient regimes, develop into ...

Robust detection protocols for uncertain introductions of invasive species

Journal of Environmental Management, 2008
Two important features of real-world port inspections of shipping containers for invasive species are the general absence of underlying economic considerations and the climate of severe uncertainty that surrounds the likelihood of invasive species introductions.

Introduction to Species of Structures

1997
Introduction This chapter contains the basic concepts of the combinatorial theory of species of structures. It is an indispensable starting point for the developments and applications presented in the subsequent chapters. We begin with some general considerations on the notion of structure, everywhere present in mathematics and theoretical computer ...

INTRODUCTION OF APPLICATION OF CHINESE WILD GRAPES SPECIES

Acta Horticulturae, 2014
China is one of the major centers of origin of Vitis species. To date, more than 38 species and varieties have been reported to originate in China among 70 known species. In the past 20 years, researchers have focused on resistance to main fungal diseases of Vitis species native to China. The results indicate that there are differences in resistance to

The local introduction of strongly interacting species and the loss of geographic variation in species and species interactions

Molecular Ecology, 2007
AbstractSpecies introductions into nearby communities may seem innocuous, however, these introductions, like long‐distance introductions (e.g. trans‐ and intercontinental), can cause extinctions and alter the evolutionary trajectories of remaining community members.

Observed and Potential Range Shifts of Native and Nonnative Species with Climate Change

Annual Review of Ecology, Evolution and Systematics
There is broad concern that the range shifts of global flora and fauna will not keep up with climate change, increasing the likelihood of population declines and extinctions.

Introduction of a Brachylaima species (Digenea: Brachylaimidae) to Australia

International Journal for Parasitology, 1990
A Brachylaima species recorded previously from the house mouse (Mus domesticus) in South Australia is shown to use the introduced European snails Cernuella virgata and Cochlicella barbara as first intermediate hosts, and the same two species and Theba pisana as second intermediate hosts. The life cycle is typical of Brachylaima species. The parasite is
