The ability of giant hogweeds to form monodominant communities and even pure monostands in invaded areas has been well documented. Understanding of the mechanisms leading to monostand formation can aid in determining the limitations of existing community ecology models and establishing an effective management plan for invasive species elimination. The aim of this observational study was to investigate traits of Heracleum sosnowskyi plants (demography, canopy structure, morphology and physiology…

Seedling Dynamics and Population Structure of Invasive Heracleum sosnowskyi (Apiaceae) in Lithuania
It is confirmed that long-term abandonment of mesic meadows promotes development of denser stands of H. sosnowskyi, and a short-time extensive management can reduce the density of monocarpic invasive species populations, especially their seedlings and immature vegetative plants.
Influence of Heracleum sosnowskyi Manden. invasion on postagrogenic soil fertility in European North-East
On the basis of field and laboratory studies, the influence of the expansion of the invasive species Heracleum sos� nowskyi on the formation of postagrogenic ecosystems in the bioclimatic conditions
How does an invasive Heracleum sosnowskyi affect soil nematode communities in natural conditions
Analysis of the effect of the invasive perennial plant Heracleum sosnowskyi on soil nematode communities and diversity, and plant species composition, by comparing invaded and non-invaded areas in natural conditions shows stress-sensitive omnivores, fungivores and root-biomass-dependent obligate plant parasites best reflected changes in soil nem atode communities under the influence of H. sosNowskyi invasion.
Rapid use of resources as a basis of the Heracleum sosnowskyi invasive syndrome
The functional properties of the invasive Heracleum sosnowskyi were compared with those of the native Heracleum sibiricum. The leaf and root traits, as well as those of a whole plant and of the
Evaluation of Heracleum sosnowskyi Frost Resistance after Snow Cover Removal in Early Spring
The development of environmentally safe and cost-effective methods for controlling invasive species Sosnowsky’s hogweed (Heracleum sosnowskyi Manden.) is an urgent issue for the European part of
Relative Growth Rate and Its Components in Invasive Species Heracleum sosnowskyi and Congeneric Native Species H. sibiricum
It is concluded that the structural and functional traits of the leaves and roots provided a 2 times higher net assimilation rate (NAR) and 2.5 times larger RGR in the invasive species H. sosnowskyi.
The impact of Sosnowsky’s Hogweed on feeding guilds of birds
It is shown that certain aspects of Sosnowsky’s Hogweed invasion may support or depress occurrence of different birds on invaded plots, and knowledge of these aspects may facilitate knowledge of the capacity for coping with challenges the invasive plants put in front of bird conservationists.
Distribution of Seeds of the Giant Hogweed (Heracleum sosnowskyi Manden.) in the Winter Period
It was found that viable seeds are preserved on the umbrellas of this alien plant in winter and measures to control Sosnowsky’s hogweed should include the destruction of dead plants with seeds until a stable snow cover is formed.
A simple mechanistic model of the invasive species Heracleum sosnowskyi propagule dispersal by wind
A simple mechanistic model is developed for the prediction of H. sosnowskyi propagule dispersal by wind and the role of wind as a vector of long-distance dispersal for invasive Heracleum species was strongly underestimated.
Seed Viability of Heracleum mantegazzianum (Apiaceae) Is Quickly Reduced at Temperatures Prevailing in Biogas Plants
The results suggest that fermentation of H. mantegazzianum biomass poses only a low risk of viable seed spread, if the operating temperature of the biogas plant achieves 42 °C and a high retention time is ensured.


Heracleum sosnowskyi (Apiaceae) seed productivity and establishment in different habitats of central Lithuania
Evaluated H. sosnowskyi spread and establishment on habitat scale in Lithuania to evaluate the speed of spread in an infected landscape and finds opportunities for colonization and reproduction resulting in decrease of natural diversity.
Invasion of Heracleum sosnowskyi (Apiaceae) at habitat scale in Lithuania
Evaluated H. sosnowskyi spread and establishment in habitat scale in Lithuania to find opportunities for colonization and reproduction resulting in decrease of natural diversity.
Invasive species of Heracleum in Europe: an insight into genetic relationships and invasion history
A close genetic relationship between the three invasive Heracleum species in Europe was found and a high overall genetic variability detected in the invaded range suggests that the majority of invading populations were not affected by a genetic bottleneck and that rapid evolution, drift, or hybridization played a role in genetic structuring of invasion populations.
It is concluded that the major evolutionary force determining the nature of the seed bank is the selective advantage derived from mechanisms of seed dormancy and germination which allow seedlings to evade the potentially-dominating effects of established plants.
Functional plasticity of photosynthetic apparatus and its resistance to photoinhibition in Plantago media
The data reveal the morphophysiological plasticity of plantain plants in relation to lighting regime and environmental conditions can facilitate the formation of the ecotype with photosynthetic apparatus resistant to photoinhibition.
Why are there so many small plants? Implications for species coexistence
Three hypotheses that require further study in the interpretation of size-dependent species richness in plants are suggested, which are based on mechanisms that have generated, for smaller plants, a greater historical opportunity for speciation.
Plant diversity and ecosystem productivity: theoretical considerations.
Three simple models of interspecific competitive interactions in communities containing various numbers of randomly chosen species predict that, on average, productivity increases asymptotically with the original biodiversity of a community and show that both species identity and biodiversity simultaneously influence ecosystem functioning.
