Abstract Aim In several ecosystems, the diversity of functional species traits has been shown to have a stronger effect on ecosystem functioning than taxonomic alone. However, few studies explored this idea at large geographical scale. multisite experiment, we unravelled relationship between function and completeness assemblages using dung beetles as model group, focusing removal secondary seed dispersal. Location Seventeen grassland locations across Western Palaearctic. Methods We used...
Abstract Dung removal by macrofauna such as dung beetles is an important process for nutrient cycling in pasturelands. Intensification of farming practices generally reduces species and functional diversity terrestrial invertebrates, which may negatively affect ecosystem services. Here, we investigate the effects cattle-grazing intensification on field experiments replicated 38 pastures around world. Within each study site, measured managed with low- high-intensity regimes to assess...
There is consensus that greater biodiversity essential to maintain the ecosystem function and stability. Variation in spatial plant community heterogeneity (β diversity) affects productivity ecosystems function; however, relatively few studies have addressed how β diversity its components (i.e. species turnover nestedness) may relate function. In this study, we assessed (richness evenness) along a gradient different bioclimatic regions including desert-steppe, steppe, semi-steppe...
Fire products have been widely identified as germination cues for a number of species from both fire-prone and fire-free ecosystems. However, there is uncertainty about the effects fire on seed semi-arid rangeland species. We examined seven dominant Central Zagros rangelands in region Iran under various heat shock (60, 80 120 °C), aerosol smoke, ash control treatments. Our findings showed that could enhance, inhibit or not affect this area. The percentage Astragalus adscendens increased...
Background: There is an increasing consensus that ecosystem processes are governed by functional identity and trait variation rather than species richness. Despite its importance, the relative effect of relevant traits for carbon storage has remained mostly untested in different bioclimatic regions.Aims: In this study, components diversity such as community-weighted means values (CWM), (Rao's quadratic diversity), richness (FRi), evenness (FEv) divergence (FDiv) were used to associate...
Question: Does grazing by large herbivores affect species composition or community‐wide variation in plant functional traits? Location: Dune grasslands at the Belgian coast. Methods: Plant cover and soil data were collected 146 plots that randomly selected 26 grazed ungrazed grassland sites. community was assessed Detrended Correspondence Analysis mean values of trait categories calculated across plots. Results: Differentiation characteristics largely determined grazing, acidity their...
Background and aims -Re-introduction of large grazers in the few remaining natural semi-natural grasslands are thought to be an effective management tool prevent dominance late successional plant species restoration biodiversity.The main objective this study was test whether introduction herbivores retard succession by reducing abundance highly competitive tall it is accompanied with changes community composition spatial distribution species.Methods -In order hypothesis, we studied effect...
Assessment of carbon storage build-up in tree stems is a difficult task due to the lack information on their sequestration potential and allocation different components. Similarly, high cost complex methodology for accurate belowground biomass estimation make it particular problematic. To this end, 18 Persian oak (Quercus brantii Lindley) trees from two growth forms western Iran were destructively sampled develop mass prediction. Sampling covered range ages (40-145-year-old), sizes (DBH 7-38...
By manipulating faeces during feeding and breeding, dung beetles (Coleoptera: Scarabaeidae) fulfil important ecosystem functions in terrestrial ecosystems throughout the world. In a pan-European multi-site experiment (MSE), we estimated of removal secondary seed dispersal by differing combinations beetle functional groups. Therefore, classified into five groups according to their body size manipulation method: dwellers, large small tunnelers, rollers. Furthermore, set up sampling database...
Ecological sustainability has been recognized as one of the main aspects sustainable development rangelands, at which different kinds animal including insects, make substantial contributions.Dung beetles, known dung-visiting play several key roles in many ecological functions from benefit both terrestrial ecosystems and human population.Specifically, they rangelands through reducing greenhouse gas emission, nutrient cycling, plant growth enhancement, trophic regulation pollination secondary...
