Neighboring plants can affect the likelihood that a focal plant is attacked by herbivores. Both the density of conspecific neighbors (resource concentration or dilution effects) and the relative density of heterospecific neighbors (associational effects or effects of neighbor frequency) within the local neighborhood can affect herbivore load and plant damage. Understanding how these neighborhoo...

SYNOPSIS. Host shifts and subsequent host-race formation likely play a more common role in the speciation of herbivorous insects than has generally been recognized. Our studies of the interactions of goldenrod host plants (Solidago: Compositae), the gall fly Eurosta solidaginis (Diptera: Tephritidae), and the stemand gall-boring Mordellistena convicta (Coleoptera: Mordellidae) provide behaviora...

BACKGROUND AND AIMS Concomitant increases in O(2) and irradiance upon de-submergence can cause photoinhibition and photo-oxidative damage to the photosynthetic apparatus of plants. As energy and carbohydrate supply from photosynthesis is needed for growth, it was hypothesized that post-submergence growth recovery may require efficient photosynthetic acclimation to increased O(2) and irradiance ...

Modelling and analysis of spatiotemporal characteristics plant invasion can help in mapping predicting the spread invasive plants. The aim our research was to investigate variability five common species (Ailanthus altissima, Asclepias syriaca, Elaeagnus angustifolia, Robinia pseudoacacia, Solidago spp.) within different land cover (ecosystem)-type categories. basis study National Geospatial Dat...

El ailanto (Ailanthus altissima (Mill.) Swingle) es una de las especies exóticas invasoras más extendida a escala global. Su principal distribución está relacionada con ambientes antropizados, donde concentraciones en suelo elementos (metales pesados o traza) pueden ser tóxicas para otros organismos vegetales. tiene la capacidad bioacumular estos contaminantes sus tejidos vegetales (hojas). Se ...

Ailanthus altissima is an invasive alien species in Europe. Biological control of this tree by Verticillium nonalfalfae a potential alternative approach. This study investigates host specificity, pathogenicity and transmission V. to neighbouring plants with root contact mini-ecosystems. led dieback all inoculated trees. Furthermore, was transmitted trees, causing wilt dieback, and, one case, Qu...

1. One of the suggested mechanisms behind success non-native plants in recipient ecosystems is competition avoidance with natives by means different resource use strategies, such as deeper water uptake under dry conditions. 2. We aimed at evaluating water-source partitioning between native and tree species coexisting central Spain floodplains; determining dependency on drought stress water-sour...
