Combining ballast water treatment and ballast water exchange: Reducing colonization pressure and propagule pressure of phytoplankton organisms
(Taylor & Francis, 2017-10)
Species richness and species abundance (colonization pressure and propagule pressure, respectively) are commonly used to characterize invasion risk for ballast-water-mediated introductions, which can be high if either ...
The interplay between propagule pressure, seed predation and ectomycorrhizal fungi in plant invasion
(Pensoft Publishers, 2019-02)
There are many hypotheses aiming to explain invasion success, but evaluating individual hypotheses in isolation may hinder our ability to understand why some species invade and others fail. Here we evaluate the interaction ...
First detailed insights into the life-history traits of the alien shrimp Athanas nitescens (Decapoda: Alpheidae) in the western Atlantic
(2021-01-01)
Information on the population biology of alien species in non-natural areas is essential to understanding their impacts on native species. Here, we investigated the life-history traits, the propagule pressure and the supply ...
Can chlorination of ballast water reduce biological invasions?
(Wiley Blackwell Publishing, Inc, 2020-02)
Ballast water has been identified as a leading vector for introduction of non-indigenous species. Recently, the International Maritime Organization implemented management standards—D-2—where all large, commercial ships ...
O pequeno forasteiro: Novas leis favorecerão a introdução de espécies não-nativas de zooplâncton em ambientes aquáticos Brasileiros
(2017-01-01)
Non-native species of zooplankton have been introduced in Brazilian continental aquatic environments for a variety of reasons (e.g., non-native fish stocking, aquaculture), but many pathways of zooplankton introductions ...
Testing alien plant distribution and habitat invasibility in mountain ecosystems: growth form matters
(Springer, 2016-04)
Most studies focused on understanding habitat invasibility use the current levels of invasion as a direct proxy of habitat invasibility. This has shown to be biased by the influence of propagule pressure and climate. We ...
An island biogeography approach for understanding changes in compositional similarity at present scenario of biotic homogenization
(ELSEVIER, 2011)
Local extinction of native species and colonization of non-native species are commonly invoked as responsible for changes in species similarity among biotas of different regions. In this study we used a model of species ...
Spatial and temporal variation in the output of gametangia of the exotic macroalga Codium fragile subsp. tomentosoides (Chlorophyta: Bryopsidales) in the subtidal zone of Caldera, Chile Variación espacial y temporal en la producción de gametangios en la m
(Universidad de Valparaiso, 2013)
The macroalga Codium fragile ssp. tomentosoides is characterized by exclusive asexual reproduction through parthenogenesis. We describe the spatial (within thallus) and temporal (seasonal) variability in the abundance of ...
