This study analyzes the variations in structure and composition of ant communities burned Pinus nigra forests central Catalonia (NE Spain). do not recover after fire, changing to shrublands oak coppices. For this reason, we suggest that P. will change because post‐fire scenario, particular with increase open areas, is different unburned one, more favourable for some species than others. In four locations previously occupied by where fires occurred 1, 5, 13 19 yr before sampling, sampled...
Plant trait information is essential for understanding plant evolution, vegetation dynamics, and responses to disturbance management. Furthermore, in Mediterranean ecosystems, changes fire regime may be more relevant than direct climatic conditions, making the knowledge of fire‐related traits especially important. Thus purpose this data set was compile most updated comprehensive on vascular species Basin, that is, related persistence regeneration after fire. Data were collected from an...
Abstract Pollination network studies are based on pollinator surveys conducted focal plants. This plant‐centred approach provides insufficient information flower visitation habits of rare species, which the majority in communities. As a result, pollination networks contain very high proportions species linked to single plant (extreme specialists), pattern that contrasts with widely accepted view plant–pollinator interactions mostly generalized. In this study Mediterranean scrubland community...
It is widely accepted that the postfire recovery in Mediterranean plant communities carried out by direct regeneration, i.e., fast of a community with same species pool it had immediately prior to disturbance. However, there evidence not all basin survive fire situations, suggesting regeneration process might apply situations. We analyze whether main combinations forest tree (up 16) western exhibit process. Based on data from field surveys, we have developed stochastic model predict...
Understanding biodiversity distribution is a primary goal of community ecology. At landscape scale, bee communities are affected by habitat composition, anthropogenic land use, and fragmentation. However, little information available on local-scale spatial within habitats that uniform at the scale. We studied along with floral nesting resources over 32 km2 area uninterrupted Mediterranean scrubland. Our objectives were (i) to analyze resource composition ask whether these follow geographical...
Abstract Apple is considered the most important fruit crop in temperate areas and profitable production depends on multiple ecosystem services, including reduction of pest damage provision sufficient pollination levels. Management approaches present an inherent trade‐off as each affects species differently. We quantified direct indirect effects management (organic vs. integrated management, IPM ) richness, 85 apple orchards three European countries. also how habit composition influenced...
Pesticides are considered a main driver of world-wide bee declines. In agricultural areas, bees exposed to combinations pesticides at low concentrations. The extent which these levels may cause sublethal effects remains unknown. Laboratory methods detect needed as first step in assessing the potential hazards Current risk assessment schemes rely on single species, highly social Apis mellifera, and provide insufficient coverage effects. Due fundamental life history differences, available...
Little is known about the impact of disturbances on functional diversity and long‐term provisioning ecosystem services, especially in animals. In this work we analyze effect wildfire composition Mediterranean ant communities. particular, asked whether a) fire changes (mean dissimilarity trait values) at community level; b) such fire‐induced modification driven by relative abundance‐dominance species or a replacement with different traits. We sampled communities burned unburned plots along 22...
Plant-pollinator systems may be considered as biological markets in which pollinators choose between different flowers that advertise their nectar/pollen rewards. Although expected to play a major role structuring plant-pollinator interactions, community-wide patterns of flower scent signals remain largely unexplored. Here we show for the first time advertisement is higher plant species bloom early flowering period when are scarce relative than blooming later season there surplus flowers. We...
Bee populations are exposed to multiple stressors, including land-use change, biological invasions, climate and pesticide exposure, that may interact synergistically. We analyze the combined effects of warming sublethal insecticide exposure in solitary bee Osmia cornuta. Previous studies show warm wintering temperatures cause body weight loss, lipid consumption, fat depletion. Because plays a key role xenobiotic detoxification, we expected bees scenarios would be more sensitive pesticides....
In agricultural environments, bees are routinely exposed to combinations of pesticides. For the most part, exposure these pesticide mixtures does not result in acute lethal effects, but we know very little about potential sublethal effects and their consequences on reproductive success population dynamics. this study, orally newly emerged females solitary bee Osmia cornuta environmentally-relevant levels acetamiprid (a cyano-substituted neonicotinoid insecticide) singly combination with...
Abstract Aim In the Mediterranean Basin, main forest communities vary in their ability to recover after fire. this study we analyse effects of fire on ant occurring various vegetation types distributed along a geographical gradient western region. Location The was carried out burned and unburned habitats 22 sites corresponding eight dryness throughout Catalonia (north‐east Spain). Methods We placed five pairs plots (one plot located area second one margin) per site. compared these 8 years...
Ants have been traditionally considered either as predators or dispersers of seeds, but not both. That is, ant dispersal is restricted to myrmecochorous while almost all seeds removed by seed‐harvesting ants are eaten. However, harvesting might be simultaneously antagonistic and mutualistic towards seeds. This study analyzes the predation–dispersal relationship between Lobularia maritima , a non‐myrmechorous perennial herb, in order disentangle dual role L. The results obtained confirm both...
Abstract Bergmann's rule originally described a positive relationship between body size and latitude in warm‐blooded animals. Larger animals, with smaller surface/volume ratio, are better enabled to conserve heat cooler climates (thermoregulatory hypothesis). Studies on endothermic vertebrates have provided support for rule, whereas studies ectotherms yielded conflicting results. If the thermoregulatory hypothesis is correct, negative relationships temperature should occur temporal addition...
Abstract Functional traits mediate the response of communities to disturbances (response traits) and their contribution ecosystem functions (effect traits). To predict how anthropogenic influence services requires a dual approach including both trait concepts. Here, we used response–effect conceptual framework understand local landscape features affect pollinator functional diversity pollination in apple orchards. We worked 110 orchards across four European regions. Orchards differed...
Abstract Question: We tested whether (1) the change in composition and structure of whole plant communities after fire is directly related to regeneration dominant tree species canopy; (2) several years decreases with proportion obligate seeders (3) increases dryness gradient. Location: Catalonia (NE Spain) Methods: measured floristic differences between burned long‐since sites eight vegetation types across a climate compared 22 burnt 1994 paired plots that had not been since 1940s. In each...
