Résumé : Die nach einheitlichen Gesichtspunkten beschriebenen Arealformen mitteleuropäischer Laubwaldpflanzen werden auf Grund ihrer zonalen, etagalen und ozeanisch-kontinentalen Bindung sowie nach ihrer unterschiedlichen Ausdehnung zu Gruppen zusammengefaßt. Das Arealtypenspektrum der west- und mitteleuropäischen Querceto-Carpineta läßt einen charakteristischen Anteil ozeanisch-subozeanischer europäischer Elemente erkennen, wie Beispiele aus Süd- und Norddeutschland, aus Kroatien und dem westungarischen Hügelland zeigen. In den letztgenannten Gebieten spielen submeridionale Arealformen eine wichtige Rolle. Das Querceto-Carpinetum Ostpolens vermittelt bereits zu osteuropäischen subkontinentalen Eichenwäldern, die von chorologischem Standpunkt aus beurteilt einen stark abweichenden Charakter haben. Auch innerhalb engerer Gebiete kann man mit Hilfe von Arealtypenspektren Waldgesellschaften, sowohl vom vergleichend-pflanzengeographischen als auch vom ökologischen Standpunkt aus charakterisieren und differenzieren. Dies wird an Beispielen aus dem Harzgebiet und dem Erzgebirgs-Vorland veranschaulicht.

[CBNPMP-Géographique] Europe centraleRésumé : One of the possible roles of secondary plant metabolites, including toxins, is facilitating plant-animal communication. Lethal cases of pasture poisoning show that the message is not always successfully conveyed. As the focus of poisoning lies in the clinical aspects, the external circumstances of pasture poisoning are widely unknown. To document poisoning conditions in cattle, sheep, goats, and horses on pastures and to compile a checklist of plants involved in either poisoning or co-existence (zero poisoning), published case reports were evaluated as primary sources. The number of affected animal individuals was estimated within abundance classes from 0 to more than 100. The checklist of poisonous plants comprised 52 taxa. Of these, 13 taxa were deemed safe (no reference was found indicating poisoning), 11 taxa were associated with evidence-based zero poisoning (positive list), and 28 taxa were associated with poisoning (negative list). Nine plant taxa caused poisoning in more than 100 animal individuals. Zero poisoning accounted for 40% and poisoning accounted for 60% of a total of 85 cases. Poisoning was most often associated with a limited choice of feed (24.7%), followed by overgrazing (12.9%), seasonally scarce feed (10.6%), and co-ingestion of grass (4.7%). Hunger interferes with plant-animal co-existence, while zero poisoning improves it. In conclusion, poisonous plants in pastures may communicate their toxicity if the animals have enough alternative feed plants. An individual animal might utterly perceive the communication of toxicity by the plant species but be forced to ignore the message owing to a limited choice of feed options.

[CBNPMP-Géographique] Europe du SudRésumé : Meadow plants of Central Europe resulting from hybridizations between mountain plants of the Alps and submediterranean plants. Various meadow plants growing in Switzerland north of the Alps are intermediate in their morphological and ecological characterstics between an alpine species and a submediterranean species. They cannot be recognised by a single independant character nor can they be distinguished from hybrids between the alpine and the submediterranean species. It is postulated that during the postglacial warming period while the areas north of the Alps were still free of forests, various alpine and submediterranean species could have come together. In the contact zone, hybridizations and gene transgressions took place. From these hybrid swarms resulted the intermediate meadow plants, which were favoured by the influence of farming man. The clearing of forests made possible further hybridizations. Therefore, the morphological and ecological limits between the original species became obscured.

Titre : Reproductive characteristics of neophytes in the Czech Republic: traits of invasive and non-invasive species Type de document : Électronique Auteurs : Lenka Moracova ; Petr Pyšek ; Vojtěch Jarošík (1958-2013) ; Vendula Havlíčková ; Petr Zákravský Année de publication : 2010 Article en page(s) : 365-390 Langues : Français (fre) Catégories : [CBNPMP-Thématique] Plantes subspontanées, naturalisées, envahissantes
[CBNPMP-Géographique] Europe centraleRésumé : This paper describes the reproductive characteristics of 93 neophytes (alien species introduced after 1500 A.D.) of the flora of the Czech Republic and compares trait values between naturalized invasive and naturalized non-invasive neophytes. Species were sampled and seed collected in the field from multiple localities in the Czech Republic. Traits related to seed production (propagule number per plant and per population), dispersal (propagule size, length/width ratio and weight; buoyancy; epizoochory; terminal velocity) and establishment (germination; seedling relative growth rate; seedling establishment) were measured for each species either in the field, in a common garden experiment or in the laboratory. Invasive species significantly differ from naturalized non-invasive species in propagule length/width ratio (by having lower ratio, i.e. more rounded propagules) and fecundity (invasive species are more fecund, both per individual plant and in terms of the population propagule production). Invasive species have proportionally fewer seedlings establishing in the autumn and better capacity for dispersal by wind than non-invasive species. The results for several traits differ depending on whether or not the effect of phylogeny is included in analytical models.
Considering species relatedness expressed as a taxonomic hierarchy, invasive species have lighter propagules and higher population propagule numbers, and marginally significantly differ in producing more propagules per plant and having higher capacity for dispersal bywater.We found that most variation in invasiveness is linked to variation among species within genera. This distribution of relatedness means that predictions of whether a species will become invasive cannot be based on traits of the relatives of the given species at higher taxonomic levels. The distinction made in this paper, i.e. invasive species vs. naturalized but non-invasive species, can potentially contribute to a deeper understanding of the role of traits associated with invasiveness because the crucial transition from the naturalized to invasion stage is rarely addressed in invasion ecology.Permalink : https://biblio.cbnpmp.fr/index.php?lvl=notice_display&id=153336
