<title>Abstract</title> Understanding how invasive plants germinate in response to shifting climatic conditions and biotic interactions is crucial for predicting preventing their spread. Species may possess a broad germination capacity that allows them under wide range of environmental conditions, or they exhibit specific responses tailored local environments. We investigated the shrub Nicotiana glauca, using seeds from its native (South America) two invaded areas Africa Spain) with...
Abstract Roadsides may homogenize the distribution of native species and act as corridors for spread alien taxa. We examined variation in plant richness composition at two spatial scales defined by altitude habitat type (edges fill slopes), well relationship between exotic roadside communities mountains from central Argentina. Following a gradient 1100 to 2200 m a.s.l. along mountain road, cover was recorded within sample plots 30 × 10 systematically located 100‐m intervals on both habitats....
Abstract Aim In order to assess the impact of precipitation changes during P leistocene glaciations on plant species atagonian steppe, a phylogeographical study endemic shrub A narthrophyllum desideratum was performed. Location S outhern atagonia: rgentina and C hile. Methods Chloroplast intergenic spacers trn – G rpo B were sequenced for 264 individuals from 33 localities spanning entire distribution . Phylogenetic (statistical parsimony, maximum likelihood ayesian inference) population...
Abstract Many invasive plant species have fleshy fruits that are eaten by native frugivorous birds which disperse their seeds and may facilitate germination, playing an important role in invasion success. The fleshy‐fruited shrub Cotoneaster franchetii (Rosaceae) is alien the mountainous regions of central Argentina. To determine avian fruit removal this species, we conducted a frugivore exclusion experiment including bagged unbagged branches 75 plants C. . At end dispersal period, compared...
Invasive plants displaying disparate pollination environments and abiotic conditions in native non-native ranges provide ideal systems to test the role of different ecological factors driving flower colour variation. We quantified corolla reflectance ornithophilous South American Nicotiana glauca populations, where are pollinated by hummingbirds, populations from two invaded regions: Africa, sunbirds, Balearic island Mallorca, reproduce selfing. Using visual modelling we examined how could...
Background: In widely distributed species, geographic patterns of phenotypic variation can appear in a clinal (linear or central–marginal) mosaic fashion response to environmental factors. Aim: We assessed spatial and possible abiotic drivers flower leaf Anarthrophyllum desideratum, an endemic legume found throughout wide gradient southern Patagonia. Methods: measured 10 floral foliar traits from 26 populations, along the entire range species. examined within among geographical patterns,...
The endemic shrub Anarthrophyllum desideratum appears to be the only ornithophilous plant offering nectar as reward in extensive Patagonian steppe. identity of its floral visitor assemblage and what extent this species depends on bird pollination for sexual reproduction is yet unknown. A. desideratum's vast distribution includes climatic gradients, which may promote geographical shifts visitors. aims study were determine dependence pollinators set fruits, identify assemblages, document...
Pollination by animals is a key process involved in flowering plants reproduction. In the educational context, this topic rarely addressed from plant-pollinator interaction point of view, and its importance poorly recognized students. Here we present didactic proposal developed to address sexual reproduction plants, based on mutualistic association. The sequence activities includes display video, observation handling flowers fruits, as well play where pollination correspondence between...
