Background and aims: Leaf litters commonly interact during decomposition in ways that can synergistically increases rates of decay. These interactions have been linked to moisture availability, suggesting that drought could slow decomposition rates by disrupting litter interactions. Slowed...

Background: Globally, pollen allergy is a major public health problem, but a fundamental unknown is the likely impact of climate change. To our knowledge, this is the first study to quantify the consequences of climate change upon pollen allergy in humans. Objectives: We produced quantitative...

The enemy release hypothesis posits that non-native plant species may gain a competitive advantage over their native counterparts because they are liberated from co-evolved natural enemies from their native area. The phylogenetic relationship between a non-native plant and the native community may...

Question: How do climate and landscape structure affect plant invasion process in south Brazilian natural grasslands? Location: Natural grasslands across Rio Grande do Sul state, southern Brazil. Methods: We selected 20 plots (2 km × 2 km each), situated in ten different grassland types in southern ...

Invasive plants colonize new environments, become pests and cause biodiversity loss, economic loss and health damage. Senecio vulgaris L. (Common groundsel, Asteraceae), a widely distributing cosmopolitan weed in the temperate area, is reported with large populations in the north-eastern and...

The family of the Asteraceae is the most diverse in the Chilean flora; nevertheless, only some tribes have undergone a recent systematic treatment, while the knowledge about the geographical distribution of the taxa is still very incomplete. From the review of herbarium specimens and fieldwork, a...

Divergence in plant traits and trait plasticity after invasion has been proposed as mechanisms favouring invasion success. Current hypotheses predict a rapid evolution in response to changes in the abiotic conditions in the area of introduction or to differences in the herbivore consumption...

Classical biological control of invasive alien weeds depends on the use of arthropod herbivores that are sufficiently host specific to avoid risk of injuring nontarget plants. Host plant specificity is usually evaluated by using a combination of behavioral and developmental experiments under...

The alien flora of the Greek island of Rodos (SE Aegean) is presented. This study is based on fieldwork carried out by the author up to June 2015, as well as on the literature found to date. The present checklist consists of 101 alien taxa of vascular plants, of which 27 are recorded for the first...

The Torres del Paine National Park (TDP) is one of the most important natural landscapes in Chile. The topographic and climatic variability of Cordillera Paine, generates environmental gradients with typical vegetation of the Sub-Antarctic Magellanic Ecoregion. However, structural and compositional ...
