Anthropogenic environmental change can increase exotic species performance and reduce native biodiversity. Nutrient enrichment may favor exotic plants with higher growth rates. Warming may increase the performance of exotic species from warmer native ranges and/or decrease the performance of...

Soil N-fixing bacteria (SNB) play an important role in the invasion by invasive plant species (IPS). Meanwhile, progressive increases in the level of anthropogenic N deposition can change both soil physicochemical properties and the ecological characteristics of soil microbial communities, with...

The availability of nitrogen and phosphorus is an important factor determining the growth and competitive dominance of invasive plants. To clarify the influence of nutrient availability on the performance of alien species, we conducted a greenhouse experiment in which the invasive plant ...

This study aims to determine the allelopathic potential of Amaranthus retroflexus (Ar) with different climatic zones on seed germination and growth of A. tricolor (At) treated with a gradient N addition. Ar leaf extracts only displayed significantly allelopathic potential on the underground growth...

Modelling disease dynamics is most useful when data are limited. We present a spatial transmission model for the spread of canine rabies in the currently rabies-free wild dog population of Australia. The introduction of a sub-clinically infected dog from Indonesia is a distinct possibility, as is...

Alternanthera philoxeroides is a perennial invasive species worldwide which can greatly affect native ecosystems and agricultural production. Our research studied the allelopathic effects of aqueous extracts of A. philoxeroides on the growth and antioxidant enzyme activities of Zoysia matrella, and ...

Both spiny and edible amaranths (Amaranthus spinosus and A. tricolor) are exotic annuals in China that produce numerous small seeds every year. Spiny amaranth has become a successful invader and a troublesome weed in Xishuangbanna, but edible amaranth has not, although it is widely grown as a...

China's South to North Water Diversion (SNWD) project connects portions of the Yangtze River in the south to the Yellow River system in the north, overcoming biogeographic barriers to water movement. The diversion will supply potable water to over 110 million people and provide multiple other...

During disease surveys conducted in September 2015 at 3 Zimbabwean farms in 3 districts, weeds in and near onion fields were found to have thrips feeding damage symptoms. Additionally, some weed leaves were chlorotic and deformed. Onion leaves and scapes had irregular, grey-to-bleached white...

This paper focuses on the occurrence, invasiveness, morphology and biology of Amaranthus palmeri in Mato Grosso, Brazil. The threats posed by this invasive weed to soyabean, maize and cotton production in Brazil are discussed and the efficacy of various methods in the control of this weed is...
