Data from: Individual variation, population-specific behaviours, and stochastic processes shape marine migration phenologies

Cameron Freshwater, Marc Trudel, Terry D. Beacham, Stéphane Gauthier, Stewart C. Johnson, Chrys-Ellen Neville & Francis Juanes
1. The phenology of long distance migrations can influence individual fitness, moderate population dynamics, and regulate the availability of ecosystem services to other trophic levels. Phenology varies within and among populations, and can be influenced by conditions individuals experience both prior to departure and encounter en route. 2. Assessing how intrinsic and extrinsic factors (e.g. individual physical condition vs. environmental conditions) interact to influence variation in migratory phenologies across ecological scales is often limited due...

Data from: Systematic deviations from linear size spectra of lake fish communities are correlated with predator-prey interactions and lake-use intensity

Ignasi Arranz, Chih-Hao Hsieh, Thomas Mehner & Sandra Brucet
Size structure of organisms at logarithmic scale (i.e. size spectrum) can often be described by a linear function with a negative slope; however, substantial deviations from linearity have often been found in natural systems. Theoretical studies suggest that greater nonlinearity in community size spectrum is associated with high predator-prey size ratios but low predator-prey abundance ratios; however, empirical evaluation of the effects of predator-prey interactions on nonlinear structures remains scarce. Here, we aim to empirically...

Data from: Associations between plant and pollinator communities under grassland restoration respond mainly to landscape connectivity

Roser Rotchés-Ribalta, Marie Winsa, Stuart P.M. Roberts, Erik Öckinger & Stuart P. M. Roberts
1. Land use change can disrupt associations between different trophic groups, but it is unclear if habitat restoration can recover these associations. In Sweden, restoration efforts have been applied to increase areas of semi-natural grassland previously remaining as small fragments due to abandonment. We assessed how the associations between plant and pollinator communities can be modified by grassland abandonment and restoration, together with landscape connectivity. 2. We surveyed plant, hoverfly and bee communities in 10...
