Bee pollinators are currently recorded with many different sampling methods. However, the relative performances of these methods have not been systematically evaluated and compared. In response to strong need record ongoing shifts in pollinator diversity abundance, global regional initiatives must adopt standardized protocols when developing large‐scale long‐term monitoring schemes. We performance six (observation plots, pan traps, variable transect walks, trap nests reed internodes or paper...
Abstract We analysed the dynamics of a plant–pollinator interaction network scrub community surveyed over four consecutive years. Species composition within annual networks showed high temporal variation. Temporal were also evident in topology network, as interactions among plants and pollinators did not remain constant through time. This change involved both number identity interacting partners. Strikingly, few species consistently present all (53% plant species, 21% pollinator 4.9%...
Declines in insect pollinators across Europe have raised concerns about the supply of pollination services to agriculture. Simultaneously, EU agricultural and biofuel policies encouraged substantial growth cultivated area pollinated crops continent. Using data from 41 European countries, this study demonstrates that recommended number honeybees required provide crop has risen 4.9 times as fast honeybee stocks between 2005 2010. Consequently, were insufficient >90% demands 22 countries...
Abstract Co‐flowering plant species commonly share flower visitors, and thus have the potential to influence each other's pollination. In this study we analysed 750 quantitative plant–pollinator networks from 28 studies representing diverse biomes worldwide. We show that for one another indirectly via shared pollinators was greater plants whose resources were more abundant (higher floral unit number nectar sugar content) accessible. The indirect also stronger between phylogenetically closer...
Summary 1. Habitat fragmentation can affect pollinator and plant population structure in terms of species composition, abundance, area covered density flowering plants. This, turn, may visitation frequency, pollen deposition, seed set fitness. 2. A reduction the quantity flower visits be coupled with a quality pollination service hence plants’ overall reproductive success long‐term survival. Understanding relationship between size and/or isolation limitation is fundamental importance for...
The EU-funded research project ALARM will develop and test methods protocols for the assessment of large-scale environmental risks in order to minimise negative human impacts. Research focuses on forecast changes biodiversity structure, function, dynamics ecosystems. This includes relationships between society, economy biodiversity.
Pollination networks are representations of all interactions between co‐existing plants and their flower visiting animals at a given site. Although the study has become distinct sub‐discipline in pollination biology, few studies have attempted to quantify spatio‐temporal variation species composition structure networks. We here investigate patterns year‐to‐year change from six different sites spanning large latitudinal gradient. quantified level persistence among years, examined network...
The structure of plant–pollinator networks has been claimed to be resilient changes in species composition due the weak degree dependence among mutualistic partners. However, detailed empirical investigations consequences introducing an alien plant into are lacking. We present first cross-European analysis by using a standardized protocol assess which particular (i.e. Carpobrotus affine acinaciformis , Impatiens glandulifera Opuntia stricta Rhododendron ponticum and Solanum elaeagnifolium )...
We studied the amino acid (AA) composition of floral nectars 73 plant species occurring in a phryganic (East Mediterranean garrigue) community and investigated whether AA sugar is shaped by evolutionary (plant phylogeny), ecological (flowering time as direct effect summer drought) coevolutionary (pollinator partnership) constraints. Our study utilised an extensive plant–pollinator matrix compiled same area where plants had been sampled. Using HPLC we detected 22 compounds/groups compounds,...
The structure of species interaction networks is important for coexistence, community stability and exposure to extinctions. Two widespread structures in ecological are modularity, i.e. weakly connected subgroups that internally highly interlinked, nestedness, specialist interact with a subset those which generalist also interact. Modularity nestedness often interpreted as evolutionary may have relevance persistence resilience against perturbations, such climate‐change. Therefore, historical...
Summary Because establishing a new population often depends critically on finding mates, individuals capable of uniparental reproduction may have colonization advantage. Accordingly, there should be an over‐representation colonizing species in which can reproduce without mate, particularly isolated locales such as oceanic islands. Despite the intuitive appeal this filter hypothesis (known Baker's law), more than six decades analyses yielded mixed findings. We assembled dataset island and...
Abstract Land-use change and intensification threaten bee populations worldwide, imperilling pollination services. Global models are needed to better characterise, project, mitigate bees' responses these human impacts. The available data are, however, geographically taxonomically unrepresentative; most from North America Western Europe, overrepresenting bumblebees raising concerns that model results may not be generalizable other regions taxa. To assess whether the geographic taxonomic...
Abstract Agricultural intensification and associated loss of high‐quality habitats are key drivers insect pollinator declines. With the aim decreasing environmental impact agriculture, 2014 EU Common Policy (CAP) defined a set habitat landscape features (Ecological Focus Areas: EFAs) farmers could select from as requirement to receive basic farm payments. To inform post‐2020 CAP, we performed European‐scale evaluation determine how different EFA options vary in their potential support...
The study of mutualistic interaction networks has led to valuable insights into ecological and evolutionary processes. However, our understanding network structure may depend upon the temporal scale at which we sample analyze data. To date, lack a comprehensive assessment scale‐dependence across wide range scales geographic locations. If is temporally scale‐dependent, constructed over different provide very perspectives on composition species interactions. Furthermore, it remains unclear how...
Abstract There is tremendous diversity of interactions between plants and other species. These relationships range from antagonism to mutualism. Interactions with members their ecological community can lead a profound metabolic reconfiguration the plants’ physiology. This favour beneficial organisms deter antagonists like pathogens or herbivores. Determining cellular molecular dialogue plants, microbes, insects, its evolutionary implications important for understanding options each partner...
Abstract Pollinators play a crucial role in ecosystems globally, ensuring the seed production of most flowering plants. They are threatened by global changes and knowledge their distribution at national continental levels is needed to implement efficient conservation actions, but this still fragmented and/or difficult access. As step forward, we provide an updated list around 3000 European bee hoverfly species, reflecting current distributional status level (in form present, absent,...
ABSTRACT Bees are essential pollinators and understanding their ability to cope with extreme temperature changes is crucial for predicting resilience climate change, but studies limited. We measured the response of critical thermal maximum (CTMax) short-term acclimation in foragers six bee species from Greek island Lesvos, which differ body size, nesting habit, level sociality. calculated ratio as a metric assess capacity tested whether bees’ was influenced by size and/or CTMax. also...
