Nutrient conditions influence allelopathic capabilities of Ludwigia adscendens and other tropical macrophytes against Microcystis aeruginosa

Freshwater Biology, Volume 69, Issue 4, Page 538-555, April 2024.
Abstract Macrophytes may release allelochemicals that suppress competing phytoplankton, although it is unclear how their effectiveness could be influenced by environmental nutrient conditions. To approach this, we conducted a series of bioassays against the bloom‐forming cyanobacterium Microcystis aeruginosa using extracts and exudates from potentially

Drivers of species composition in arable‐weed communities of the Austrian–Hungarian borderland region: What is the role of the country?

Applied Vegetation Science, Volume 27, Issue 1, January/March 2024.
We studied the weed vegetation of six summer annual crops in the borderland region of Austria and Hungary. Our results suggest that the distinct historical agronomical background of the two countries still has an impact on the weed species composition of arable fields.

Influence of local environmental gradients on ecological strategies of herbaceous communities in riverine side channels

Journal of Vegetation Science, Volume 35, Issue 1, January/February 2024.
Former and secondary arms concentrate strong environmental gradients and plant diversity at fine spatial scale. The role of disturbance and stress‐related parameters for community structure and ecological strategies was assessed. Results highlighted five structuring parameters for taxonomic composition.

Contribution of soil seed banks to vegetation resilience in coastal freshwater wetlands of subtropical Australia

Journal of Vegetation Science, Volume 35, Issue 1, January/February 2024.
This study explores the diversity of soil seed banks in coastal freshwater wetlands of subtropical Australia and the role they have in supporting vegetation resilience under climate change. Seed banks, although diverse and highly varied, minimally reflected the standing vegetation, which suggests strong potential for transformation of this community ...

Plant Biodiversity, Wetland Indicators, and Ecosystem Analysis of Human‐Made Wetlands in Central Ethiopia

International Journal of Ecology, Volume 2024, Issue 1, 2024.
Despite vital in conserving biodiversity, most natural wetlands were degraded and declined in numbers due to anthropogenic factors, thereby human‐made wetlands have been established in Ethiopia. Thus, this study aimed to analyze plant diversity, wetland indicators, characteristic species, and ecosystem conditions of Ethiopian highland human‐made ...

Content of phytohormones in generative organs of Persicaria amphibia (L.) Delarbre for various growth conditions

Studia Biologica, 2012
The content of phytohormones in the generative organs of Persicaria amphibia (L.) Delarbre in different conditions of growth was studied. It was shown that the generative organs of water forms of P. amphibia were characterized by high indolil-3-acetic acid (IAA) and ethylene, and dry valley form – by more cytokinins (CK), abscisic acid (ABA) and ...

Morphological traits of gynodioecious Persicaria amphibia (Polygonaceae)

Phytotaxa, 2015
Gynodioecy, as intermediate sexual system, involves modifications of floral structure from hermaphrodites to dioecy. We here present the morphological differences in the sexual type of flowers concerning the terrestrial Persicaria amphibia as a gynodioecious species. Hermaphroditic flowers are relatively larger than female ones, and they produce viable
