Temperature and predator cues interactively affect ontogenetic metabolic scaling of aquatic amphipods

Vojsava Gjoni, Alberto Basset & Douglas S. Glazier
A common belief is that body-mass scaling of metabolic rate results chiefly from intrinsic body-design constraints. However, several studies have shown that multiple ecological factors affect metabolic scaling. The mechanistic basis of these effects is largely unknown. Here, we explore whether abiotic and biotic environmental factors have interactive effects on metabolic scaling. To address this question, we studied the simultaneous effects of temperature and predator cues on the ontogenetic metabolic scaling of amphipod crustaceans inhabiting...

Data from: Interactive effects between physical forces and ecosystem engineers on seed burial: a case study using Spartina anglica

Zhenchang Zhu, Francesco Cozzoli, Nanyang Chu, Maria Salvador, Tom Ysebaert, Liquan Zhang, Peter M. J. Herman & Tjeerd J. Bouma
Seed burial (i.e. vertical seed dispersal) has become increasingly valued for its relevance for seed fate and plant recruitment. While ecosystem engineers have been generally considered as the most important drivers of seed burial, the role of physical forces, such as wind or water flow, has been largely overlooked. Using tidal habitats as a model system, and a combination of flume and mesocosm experiments, we investigated the effects of 1) currents, 2) benthic animals with...

Data from: Population genomics meet Lagrangian simulations: oceanographic patterns and long larval duration ensure connectivity among Paracentrotus lividus populations in the Adriatic and Ionian seas

Connectivity between populations is a key factor that influences both their dynamics and the genetic structuring of marine species. In this study, we explored connectivity patterns of a long-dispersing species, the edible common sea urchin Paracentrotus lividus, focusing mainly on the Adriatic-Ionian basins. We applied a multidisciplinary approach integrating population genomics, based on 1122 Single Nucleotide Polymorphisms (SNPs) obtained by 2b-RAD in 275 samples, with Lagrangian simulations performed with a biophysical model of larval dispersal....

Data from: Contextualizing macroecological laws: A big data analysis on electrofishing and allometric scalings in Ohio, USA

Christian Mulder & Giorgio Mancinelli
We investigated the influence of different electrofishing methods on allometric scaling features of fish assemblages in lotic environments. The ultimate aim was to elucidate to which extent the structure of fish assemblages is predictable by the three-quarter power law theory. Water bodies across the state of Ohio, USA, provided a suitable data set to analyze the size–biomass spectra of 2051 fish assemblages. For the first time, 41,070 allometric field observations were screened according to sampling...

Data from: When feeling younger depends on others: the effects of social cues on older consumers

Cesare Amatulli, Alessandro M. Peluso, Gianluigi Guido & Carolyn Yoon
How do social cues in the immediate environment affect older consumers’ tendency to feel younger? And what is the impact of this tendency on consumption? This research investigates the malleability of older consumers’ feel-age and the underlying mechanisms by focusing on the influence of contextual social cues and the downstream effects on consumption behavior. Five experiments provide evidence that the mere presence of young social cues triggers an identity threat for older consumers; and feeling...

Shape matters: The relationship between cell geometry and diversity in phytoplankton

Alexey Ryabov, Onur Kerimoglu, Irina Olenina, Leonilde Roselli, Alberto Basset, Elena Stanca, Elena Litchman & Bernd Blasius
We compiled the most comprehensive data set of phytoplankton and other marine protists in terms of sizes, shapes, genus, and species names. Samples were obtained from seven globally distributed marine areas: Baltic Sea, North Atlantic (Scotland), Mediterranean Sea (Greece and Turkey), Indo-Pacific (the Maldives), South-western Pacific (Australia), Southern Atlantic (Brazil). See details in Ryabov et al Ecology Letters 'Shape matters: the relationship between cell geometry and diversity in phytoplankton', https://doi.org/10.1111/ele.13680

Tuning cell behavior with nanoparticle shape

Loris Rizzello, Alessandro Poma, Eva Liatsi-Douvitsa, Giuseppe Battaglia, Valeria De Matteis, Cesare De Pace, Adrian Joseph, Claudia Contini, Edoardo Scarpa, Josep Martí, Loris Rizzello & Senio De Souza
We investigated how the shape of polymeric vesicles, made by the exact same material, impacts the replication activity and metabolic state of both cancer and non-cancer cell types. First, we isolated discrete geometrical structures (spheres and tubes) from a heterogeneous sample using density-gradient centrifugation. Then, we characterized the cellular internalization and the kinetics of uptake of both types of polymersomes in different cell types (either cancer or non-cancer cells). We also investigated the cellular metabolic...

Phytoplankton data collected in the port of Otranto, Apulia, Italy.

Federica Lugoli & Alberto Basset
The dataset is part of a Master degree study on the organization of phytoplankton communities in the harbour of Otranto. Taxonomic and morphological phytoplankton data are collected in the Otranto's harbour (Apulia Region, Italy).

Data from: Matching genetics with oceanography: directional gene flow in a Mediterranean fish species

Celia Schunter, Josep Carreras-Carbonell, Enrique Macpherson, Joaquin Tintoré, Enrique Vidal-Vijande, Ananda Pascual, Paolo Guidetti & Marta Pascual
Genetic connectivity and geographic fragmentation are two opposing mechanisms determining the population structure of species. While the first homogenizes the genetic background across populations the second one allows their differentiation. Therefore, knowledge of processes affecting dispersal of marine organisms is crucial to understand their genetic distribution patterns and for the effective management of their populations. In this study, we use genetic analyses of eleven microsatellites in combination with oceanographic satellite and dispersal simulation data to...
