alcanos lineales de la cera cuticular de hojas de populus alba populus deltoides salicaceae Robinia pseudoacacia fabaceae ulmus pumila ulmaceae y fraxinus americana oleaceae en tandil buenos aires argentina
Darwiniana (Argentina) Num.1 Vol.44, 2015Co-Authors: Maria L Bakker, Patricia I AlvaradoAbstract:Mature leaves of adult individuals of Populus alba, Populus deltoides, Robinia pseudoacacia, Ulmus pumila and Fraxinus americana from the University Campus, Tandil, Buenos Aires, Argentina (37° 19 S, 59° 08 W) were collected on February 2004. The cuticular wax was extracted, purified, and the content and relative proportion of odd-carbon numbered n-alkanes (C23 #56256; #56394;C35) was quantified by capillary gas-liquid chromatography. Total concentration of n-alkanes (mg/kg DM) were P. alba (6935) Robinia (1571) P. deltoides (1379) Ulmus (880) Fraxinus (467). Most abundant n-alkanes in all species were C27 and C29 accounting for 10-51% and 35-76% of total, respectively, except Fraxinus where most abundant were C29 and C31 accounting for 31% and 41% of total, respectively. P. alba and P. deltoides differed not only in total concentration of all n-alkanes but also in relative proportion of C27 and C29, being C29 the most abundant in the latter species (76%) as well as in Robinia (75%). The occurrence of even-carbon numbered n-alkanes was either undetectable or very low in all species in general, except for C26, C28 and C30, the latter being prominent in Fraxinus.

Two additions to the Iberian myrmecofauna: Crematogaster inermis Mayr, 1862, a newly established, tree-nesting species, and Trichomyrmex mayri (Forel, 1902), an emerging exotic species temporarily nesting in Spain (Hymenoptera, Formicidae)
2020Co-Authors: Consorci Del Museu De Ciències Naturals De Barcelona, Casiraghi Alice, Espadaler Xavier, Pérez Hidalgo Nicolás, Gómez KikoAbstract:Abstract Exotic ants are a growing component of urban and disturbed habitats worldwide. Sampling in two Iberian Mediterranean localities revealed several exotic species. The tree-nesting, black acrobat ant Crematogaster inermis Mayr, 1862, has been detected nesting outdoors on a Robinia pseudoacacia tree in a public garden in Valencia (Spain) and represents a new addition to the continental European fauna. Collection details, a morphological description, biometry, and the remarkable presence of short spines in smaller specimens are also given for this species. A case of an ephemeral establishment of several exotic ant species in a palm grove is also discussed. This case includes C. inermis and Trichomyrmex mayri, also a novelty for the Iberian Peninsula. Keywords Aphis craccivora, Crematogaster inermis, Robinia pseudoacacia, Trichomyrmex mayri, Spai

Robinia pseudoacacia dominated vegetation types of southern europe species composition history distribution and management
Science of The Total Environment, 2020Co-Authors: Michaela Vitkova, Jan Rolecek, Jiři Sadlo, Petr Petřik, Tommaso Sitzia, Jana Mullerova, Petr PysekAbstract:Knowledge of the species composition of invaded vegetation helps to evaluate an ecological impact of aliens and design an optimal management strategy. We link a new vegetation analysis of a large dataset to the invasion history, ecology and management of Robinia pseudoacacia stands across Southern Europe and provide a map illustrating Robinia distribution. Finally, we compare detected relationships with Central Europe. We show that regional differences in Robinia invasion, distribution, habitats and management are driven both by local natural conditions (climate and soil properties, low competitive ability with native trees) and socioeconomic factors (traditional land-use). Based on the classification of 467 phytosociological releves we distinguished five broad vegetation types reflecting an oceanity-continentality gradient. The stands were heterogeneous and included 824 taxa, with only 5.8% occurring in more than 10% of samples, representing mainly hemerobic generalists of mesophilous, nutrient-rich and semi-shady habitats. The most common were dry ruderal stands invading human-made habitats. Among native communities, disturbed mesic and alluvial forests were often invaded throughout the area, while dry forests and scrub dominated in Balkan countries. Continuous, long-term and large-scale cultivation represent a crucial factor driving Robinia invasions in natural habitats. Its invasion should be mitigated by suitable management taking into account adjacent habitats and changing cultivation practices to select for native species. Robinia invasion has a comparable pattern in Central and Southern Europe, but there is a substantial difference in management and utilization causing heterogeneity of many South-European stands.

black locust Robinia pseudoacacia beloved and despised a story of an invasive tree in central europe
Forest Ecology and Management, 2017Co-Authors: Michaela Vitkova, Jiři Sadlo, Jana Mullerova, Jan Pergl, Petr PysekAbstract:Robinia pseudoacacia, invaded many countries a long time ago and is now a common part of the Central European landscape. Positive economic but negative environmental impacts of Robinia result in conflicts of interest between nature conservation, forestry, urban landscaping, beekeepers and the public when defining management priorities. Because current legislation will determine the future distribution of Robinia in the landscape, a comprehensive view of this species is necessary. Although this species is well studied, most of the scientific papers deal with the economic aspects. Other information is published in local journals or reports. Therefore we reviewed the ecological and socio-economic impact of Robinia placing particular emphasis on the species' history, vegetation ecology, invasiveness and management. In Central Europe, Robinia is limited climatically by late spring frost combined with a short vegetation period, soil hypoxia, shade and frequent major disturbances. The long historical tradition of using Robinia for afforestation has resulted in its popularity as a widespread forest tree and it being an important part of the economy in some countries. The main reasons are its fast growth, valuable and resistant wood, suitability for amelioration, reclamation of disturbed sites and erosion control, honey-making and recently dendromass production. On the other hand, a side-effect of planting this nitrogen-fixing pioneer tree, very tolerant of the nature of the substrate, is its propagation and spread, which pose a problem for nature conservation. Robinia is considered invasive, threatening especially dry and semi-dry grasslands, some of the most species-rich and endangered types of habitat in the region, causing extinction of many endangered light-demanding plants and invertebrates due to changes in light regime, microclimate and soil conditions. Other often invaded habitats include open dry forests and shrubland, alluvial habitats, agrarian landscapes, urban and industrial environments and disturbed sites, e.g. post-fire sites, forest clearings or degraded forestry plantations. Without forestry, black locust abundance would decrease during succession in forests with highly competitive and shade tolerant trees and in mature forests it occurs only as admixture of climax trees. The limited pool of native woody species, lack of serious natural enemies and a dense cover of grasses and sedges can suppress forest succession and favour the development of Robinia monodominant stands over 70 years old. A stratified approach, which combines both tolerance in some areas and strict eradication at valuable sites, provides the best option for achieving a sustainable coexistence of Robinia with people and nature.
