Summary Sometimes it was supposed, that the invading species of North American origin Bidens frondosa removes the indigenous B. tripartita. The aim of this study was to look for some evidence. Comparing germination pattern, growth, dry matter production, reproductive features, and architecture of both species it is obvious that B. frondosa is able to outcompete B. tripartita. In D e W it -replacement series it can be shown that B. tripartita is supressed under high, medium and low nutritional… Expand
A modelling approach for evaluating phenology and adaptation of two congeneric weeds (Bidens frondosa and Bidens tripartita).
TLDR
To characterise and model the phenology of the two species, a two-year study was conducted involving sowings at 15-day intervals between March and August, and B. frondosa resulted as being less macrothermal and more sensitive to photoperiod. Expand
Dormancy and germination of heteromorphic achenes of Bidens frondosa
TLDR
Bidens frondosa is an annual weed occurring on mudflats with heteromorphic achenes that is morphologically better-adapted for dispersal by animals and their deeper dormancy and slower germination might be a strategy to reduce the risk of germination in new, unfavourable habitats. Expand
River corridor plants (Stromtalpflanzen) in Central European lowland: a review of a poorly understood plant distribution pattern
Aim and location In Central European lowlands certain plant species grow mainly or exclusively in the corridors of large rivers. In German-speaking plant geography, they are known asExpand
Vegetation and future natural development of plantations with the Black poplar hybrid Populus×euramericana Guinier introduced to Central Europe
Abstract Plantations of the Black poplar hybrid Populus×euramericana Guinier, introduced to Europe, are widely spread especially in floodplains. Within the Spree forest (NE Germany) as aExpand
Performance and responses to competition in two congeneric annual species: does seed heteromorphism matter?
TLDR
Compared performance and response to competition among distinct seed morph progenies in two congeneric, co-occurring species: the invasive Bidens frondosa and the non-invasive Bidens tripartita, it is hypothesised that maintainer seed morphs of both species would perform better under increased plant densities and within inter-morphic mixtures, while coloniser morphs would show stronger responses to increased density and perform relatively poorly in inter- morphic mixture.

Plant Competitive Interactions and Invasiveness: Searching for the Effects of Phylogenetic Relatedness and Origin on Competition Intensity
TLDR
It is found that competition intensity was not influenced by the relatedness or origin of competing neighbors, and none of the three mechanisms investigated is likely to be a principal driver of their invasiveness. Expand
Antibacterial and antioxidant activities of the essential oil and methanol extracts of Bidens frondosa Linn
Antibacterial and antioxidant potential of essential oil, extract and its fractions of Bidens frondosa Linn were evaluated. Sixty-one components representing 95.41% of the total oil were identified.Expand
The Importance of Local and Regional Factors on the Vegetation of Created Wetlands in Central Europe
We assessed the relative importance of regional and local processes to wetland plant diversity in created depressional wetlands in Central Europe (Košské mokrade wetlands, central Slovakia). TwelveExpand
Introduction bias: Cultivated alien plant species germinate faster and more abundantly than native species in Switzerland
TLDR
The results suggest that biased introduction and human-mediated selection of ornamental plants with these characteristics might increase the risk that these species ultimately become invasive, and it is important that studies testing for determinants of invasiveness include non-invasive alien species in addition to invasive alien species.

Инвазивные виды растений, т.е. активно расселяющиеся агрессивные чужеродные виды с высокой конкурентной способностью и репродуктивным успехом, нередко натурализуются в естественных фитоценозах,Expand

The Pioneer Vegetation of Exposed Muds and Its Biological Features
TLDR
It is emphasized that the diversity of biological characteristics, which experimental cultures reveal, in the offspring of different individuals (termed 'polybiosis') may be of great importance for the exploitation of abnormal circumstances and perhaps even for survival. Expand
A COMPARATIVE STUDY OF GERMINATION CHARACTERISTICS IN A LOCAL FLORA
TLDR
Under constant temperature conditions, the majority of grasses, legumes and composites germinated over a wide range of temperature, and the same feature was evident in species of ubiquitous or southern distribution in the British Isles. Expand
Introduction, establishment and replacement of sea-rockets (Cakile, Cruciferae) in Australia
Cakile edentula (Bigel.) Hook., native to sandy beaches of eastern North America, was first collected in Australia in the 1860s near Melbourne; it presumably was introduced in ships' ballast. WithinExpand
Competition and Coexistence of Similar Species
TLDR
An ecologist may approach the problem by finding some phenotypic character, morphological or physiological, that differs systematically among a group of similar plants and then ascribe to those differences a mechanism(s) that allows coexistence. Expand
