1. Diurnal plant–visitor networks are well studied, but the community-level dimension of nocturnal visitation by insects has been largely overlooked. 2. This study focused on role moths as pollen vectors in a boreal pine forest Scotland. Light traps were used to sample 20 plots two consecutive years. The moths' bodies was identified and grains counted. information build pollen-transport network for each year. These first characterise community. 3. A total 4162 belonging 103 species captured;...
Identifying large-scale patterns of variation in pollinator dependence (PD) crops is important from both basic and applied perspectives. Evidence wild plants indicates that this can be structured latitudinally. Individuals populations at high latitudes may more selfed less dependent on pollinators due to higher environmental instability overall lower temperatures, conditions affect availability. However, whether pattern similarly present remains unknown. Soybean (Glycine max), one the most...
Patterns of variation in plant–pollinator (p–p) systems response to environmental variables have been the focus much recent attention. We analyzed species diversity and generalization interactions flower visitors belonging eight p–p networks along a steep rainfall gradient NW Patagonia, Argentina. To our knowledge, this is first published study that applies humidity‐gradient approach analysis. Throughout gradient, we recorded 1232 between 413 different animal 111 plant species. found (a)...
Summary The ongoing biodiversity crisis entails the concomitant loss of species and ecological services they provide. Global defaunation, particularly frugivores, may negatively affect seed dispersal fleshy‐fruited plant species, with predictable stronger impacts in simplified communities such as those on oceanic islands. However, logistical difficulties have hindered experimental theoretical need to disentangle roles identity, richness (i.e. number species) abundance. Consequently, studies...
Abstract Managing agricultural environments in a way that maximises the provision of multiple ecosystem services is significant challenge development sustainable and secure food systems. Advances network ecology provide forward, particularly arable landscapes, as they incorporate mutualistic antagonistic interactions associated with crop production. Here, we present an approach to identify mixes non‐crop plant species while minimising disservices. Genetic algorithms were applied Norwood Farm...
The assemblages of visitors to angiosperms flowering at a montane and high alpine site in the Andes Mendoza, Argentina (33–34°S) were described plant-flower visitor matrices analyzed compared other systems, particular those located similar latitude on western slope Andes. In low-altitude (montane) habitat, 23 plant species had total 126 interactions with 71 taxa insects one hummingbird, higher 21 plants 45 insect 83 interactions. Connectances 7.6 8.7, respectively. Diptera Hymenoptera...
The global challenge of feeding two billion more people by 2050, using sustainable agricultural practices whilst dealing with uncertainties associated environmental change, requires a transformation food systems. We present new perspective for how advances in network science can provide novel ways to better understand, harness, and restore multiple ecological processes environments. describe: (i) network-focused framework managing agro-ecosystems that accounts the interactions between...
ABSTRACT Understanding the pollination mechanisms of “settling moths” (moths from families other than Sphingidae typically perched on corollas while feeding flowers) in Neotropics is crucial for assessing their contributions to plant reproduction and ecosystem resilience. Through extensive literature searches Google Scholar SCOPUS, this study identified 44 relevant studies an initial pool 410. These covered 37 ecoregions across over 30 million km 2 , primarily focusing natural habitats, with...

During two seasons of field sampling in crop fields Argentina, a total 2,276 Aphidiinae specimens were collected using Malaise traps positioned maize, soybean, and wheat fields. Eight known species aphid parasitoids identified ( Aphidius platensis Brethes, 1913, A. ervi Haliday, 1834, rhopalosiphi de Stefani-Perez, 1902, uzbekistanicus Luzhetzki, 1960, matricariae Diaeretiella rapae (McIntosh, 1855), Lysiphlebus testaceipes (Cresson, 1880), Praon gallicum Starý, 1971). Additionally, new...
A new species of Aspilota without a mesoscutal pit, A.murieli Peris-Felipo, sp. nov., is described and illustrated from Argentina. The genus Foerster, 1863 recorded Argentina for the first time. key to Neotropical provided.
Abstract Recent studies have assessed the influence of different types gradients (e.g. altitudinal, latitudinal and temporal, among others) on structure function community‐level plant‐pollinator webs. Although importance humidity as a major driver species‐richness worldwide has been stressed by recent reviews, no specifically designed to address precipitation pollination In present paper we describe for first time turnover species plants their associated flower visitors between eight...
Abstract The pollination ecology of eight populations the tree Embothrium coccineum was studied along a steep rainfall gradient in NW Patagonia, Argentina. showy red flowers suggest an ornithophilous syndrome and they have been reported to attract hummingbirds Argentina passerines Chile. At each population, flower visitors were recorded floral rewards analysed. We found highly significant increase nectar concentration towards drier end gradient, but this change not related turnover species...
Bipartite graphs have received some attention in the study of social networks and biological mutualistic systems. A generalization a previous model is presented, that evolves topology graph order to optimally account for given contact preference rule between two guilds network. As result, are classified as belonging clearly different classes. Projected graphs, linking agents only one guild, obtained from original bipartite graph. The corresponding evolution its statistical properties also...
Bumble bees can forage on a large number of wild plants and crops. The survival colony depends the availability suitable food resources within foraging range throughout their season. We studied spatial temporal use floral by bumble in set 30 local plant communities used these data to model under different combinations patch size bee flight distance. Floral vary spatially temporally at landscape level, track across during simulation showed that patterns could affect distribution nests...
Abstract Seasonal turnover in plant and floral visitor communities changes the structure of network interactions they are involved in. Despite dynamic nature plant–visitor networks, a usual procedure is to pool year‐round interaction data into single which may result biased depiction real network. The annual temporal dynamics effect merging monthly have previously been described for qualitative ( i.e. describing occurrence interactions) alone, while its quantitative aspect actual frequency...
