Asch. & Graebn., 1900 Résumé : Whether the success of alien species can be explained by their functional or phylogenetic characteristics remains unresolved because of data limitations, scale issues and weak quantifications of success. Using permanent grasslands across France (50 000 vegetation plots, 2000 species, 130 aliens) and building on the Rabinowitz's classification to quantify spread, we showed that phylogenetic and functional similarities to natives were the most important correlates of invasion success compared to intrinsic functional characteristics and introduction history. Results contrasted between spatial scales and components of invasion success. Widespread and common aliens were similar to co-occurring natives at coarse scales (indicating environmental filtering), but dissimilar at finer scales (indicating local competition). In contrast, regionally widespread but locally rare aliens showed patterns of competitive exclusion already at coarse scale. Quantifying trait differences between aliens and natives and distinguishing the components of invasion success improved our ability to understand and potentially predict alien spread at multiple scales.

Do poisonous plants in pastures communicate their toxicity? Meta-study and evaluation of poisoning cases in central europe / Sabine Aboling in Animals, 13 (24) (2023) 

Public Citation [article]  inAnimals > 13 (24) (2023) . - 1-26 Titre : Do poisonous plants in pastures communicate their toxicity? Meta-study and evaluation of poisoning cases in central europe Type de document : Imprimé Auteurs : Sabine Aboling Année de publication : 2023 Article en page(s) : 1-26 Catégories : [CBNPMP-Thématique] Toxicité végétale [LOTERRE-Biodiversité] Écotoxicologie [CBNPMP-Géographique] Europe centrale Résumé : 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.

Intoxications par Phytolacca americana dans le Sud-Ouest / Antoine Rampnoux (2016) 

Public Citation Titre : Intoxications par Phytolacca americana dans le Sud-Ouest Type de document : Électronique Auteurs : Antoine Rampnoux Editeur : Bordeaux : Université de Bordeaux. Sciences pharmaceutiques Année de publication : 2016 Importance : 121 p. Catégories : [LOTERRE-Biodiversité] Écotoxicologie [CBNPMP-Géographique] Sud-Ouest [CBNPMP-Thématique] Toxicité végétale Résumé : Le Phytolaque, Phytolacca americana, est une Phytolaccacée dont la richesse en composés actifs n’a pas encore livré tous ses secrets. Longtemps utilisé en médecine traditionnelle, notamment outre Atlantique, son utilisation contemporaine est plus limitée, mais pourrait connaître un renouveau, suite à des découvertes et des études récentes en cancérologie et infectiologie. 139 cas d’intoxications par le Phytolaque dans le Sud-Ouest de juillet 2008 à décembre 2014 ont été analysés. Le risque d’intoxication par ingestion s’explique principalement par son caractère ornemental, la densité de sa population, et la toxicité variable de ses différents organes. Les enfants sont les plus touchés, notamment ceux entre un et trois ans, qui représentent près de sept cas sur dix. Les baies sont incriminées dans 85 % des cas, et leur arrivée à maturité durant les mois d’août, septembre et octobre permet d’expliquer le caractère saisonnier. En effet, ces trois mois représentent 85 % des intoxications. Si on retrouve des troubles digestifs dans près de 80 % des cas symptomatiques, l’intoxication est dans la grande majorité asymptomatique, et considérée quasiment sans risque. La racine fait exception, sa toxicité importante la rend beaucoup plus dangereuse que les autres organes. Son caractère envahissant fait également débat, et suscite une attention particulière dans certains massifs forestiers.

Major toxic plants and their effect on livestock: a review / Belay Walelign in Advances in life science and technology, 45 (2016) 

Public Citation [article]  inAdvances in life science and technology > 45 (2016) . - 1-12 Titre : Major toxic plants and their effect on livestock: a review Type de document : Imprimé Auteurs : Belay Walelign ; Enyew Mekuriaw Année de publication : 2016 Article en page(s) : 1-12 Catégories : [CBNPMP-Thématique] Toxicité végétale [LOTERRE-Biodiversité] Écotoxicologie Résumé : Poisonous plants are major causes of economic loss to the livestock industry. Each year these plants adversely affect 3 to 5 percent of the cattle, sheep, goat, and horses that graze ranges. These losses result from death of livestock, abortions, photosensitization, decreased production, emaciation, and birth defects. In addition to these losses are those of increased management costs associated with such things as fencing, altered grazing programs, and loss of forage. Suggestions are included for the prevention of livestock poisoning by plants. Various species and classes of livestock are reported to be affected by toxic plants particularly in the dry and early rainy seasons when feed is in short supply. A more extensive survey is required to document all poisonous plants in the rangelands and to identify the major toxic principles in the different species possibly pharmacological activity. This review presents the current knowledge on the identity of plants known to have poisoned livestock and research conducted into these toxic plants. Many of the plants identified are considered toxic on the basis of world literature. Research is needed to determine not only which plants represent a potential risk for animal health and production but also their photochemistry and toxicology. It is strongly recommended that veterinarians document plant poisoning cases through government reporting services and that university and government veterinarians, scientists, and extension agents investigate episodes of plant toxicosis and publish their findings. This would help identify toxic species for further photochemical and toxicological studies and possibly pharmacological activity.
