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...

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...

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...

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...

Mikania cordata, an invasive weed is becoming a problem in the secondary degraded forests and plantations of Bangladesh, not only competing with but also releasing allelochemicals to cultivated crops. Allelopathic effects of the leaves of M. cordata were investigated through an experiment in the...

The share of endangered and invasive species in field communities was presented in the paper. Floristic studies were carried out between 2010 and 2013 in agricultural cultivations of the Maciejowice commune. A rich flora of this area consists of 216 species and includes 21 taxa belonging to various ...

The amount of litter and its type can affect seedling establishment and species richness in plant communities. However, little is known about the species-specific effects of litter, especially in the presence of a competitor. We conducted a common garden test to examine the combined effects of...

Our tests were carried out in Kunpeszér, the Kiskunság National Park. The coenological recordings were made in 2×2 meter quadrates. We found out species composition and coverage. In the test area mostly Achilleo-Festucetum pseudovinae (grass saline desert) grassland was located. The grassland...

Resource pulses are a common event in agro-ecosystems. A pot experiment was conducted to assess the effects of nitrogen (N) pulses and competition on the growth of an invasive weed, Amaranthus retroflexus, and a native crop, Glycine max. A. retroflexus and G. max were planted in pure culture with...
