Data from: Evolution of wing length and melanin-based coloration in insular populations of a cosmopolitan raptor

ANDREA ROMANO
Aim. Insular populations face different conditions than those living on continents, thus resulting in the evolution of typical insular phenotypes, like smaller body sizes or reduced colourations. However, the generality of the so-called “island rule” has been questioned, and intraspecific analyses on the effects of insularity on cosmopolitan species are lacking. Here, we tested the predictions of the island rule in the cosmopolitan common barn owl group. Location. World. Taxon. Barn owl species complex. Methods....

Effects of soil preservation for biodiversity monitoring using environmental DNA

Alessia Guerrieri, Aurélie Bonin, Tamara Münkemüller, Ludovic Gielly, Wilfried Thuiller & Gentile Francesco Ficetola
Environmental DNA metabarcoding is becoming a key tool for biodiversity monitoring over large geographical or taxonomic scales and for elusive taxa like soil organisms. Increasing sample sizes and interest in remote or extreme areas often require the preservation of soil samples and thus deviations from optimal standardized protocols. However, we still ignore the impact of different methods of soil sample preservation on the results of metabarcoding studies and there is no guidelines for best practices...

Proactive conservation to prevent habitat losses to agricultural expansion

David Williams, Michael Clark, Graeme M. Buchanan, G. Francesco Ficetola, Carlo Rondinini & David Tilman
The projected loss of millions of square kilometres of natural ecosystems to meet future demand for food, animal feed, fibre, and bioenergy crops is likely to massively escalate threats to biodiversity. Reducing these threats requires a detailed knowledge of how and where they are likely to be most severe. We developed a geographically explicit model of future agricultural land clearance based on observed historic changes and combine the outputs with species-specific habitat preferences for 19,859...

The HCN domain couples voltage gating and cAMP response in hyperpolarization-activated cyclic nucleotide-gated channels

Andrea Saponaro, Federica Gasparri, Daniel Bauer, Christine Gross, Matteo Pisoni, Gerardo Abbandonato, Kay Hamacher, Bina Santoro, Anna Moroni, Alessandro Porro & Gerhard Thiel
Hyperpolarization-activated cyclic nucleotide-gated (HCN) channels control spontaneous electrical activity in heart and brain. Binding of cAMP to the cyclic nucleotide-binding domain (CNBD) facilitates channel opening by relieving a tonic inhibition exerted by the CNBD. Despite high resolution structures of the HCN1 channel in the cAMP bound and unbound states, the structural mechanism coupling ligand binding to channel gating is unknown. Here we show that the recently identified helical HCN-domain (HCND) mechanically couples the CNBD and...

Data from: Extra food provisioning reduces extra-pair paternity in the lesser kestrel (Falco naumanni)

Alessandra Costanzo, Nicola Tommasi, Andrea Galimberti, Giorgia Scesa, Roberto Ambrosini, Matteo Griggio, Jacopo G. Cecere & Diego Rubolini
Female promiscuity can function to acquire both direct and indirect benefits from their social mate and extra-pair males. In many raptor species, intense mate-feeding significantly contributes to female energy requirements before and during egg laying. Moreover, females may use mate-feeding effort to assess male quality. In this study of the lesser kestrel (Falco naumanni), we aimed at experimentally manipulating the female’s perception of mate quality by providing females with extra food during egg laying, and...

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...

Data from: Co-foundress confinement elicits kinship effects in a naturally sub-social parasitoid

Ian C. W. Hardy, Daniela Lupi & Mohamed K. Abdi
Kinship among interacting individuals is often associated with sociality and also with sex ratio effects. Parasitoids in the bethylid genus Goniozus are sub-social, with single foundress females exhibiting post-ovipositional maternal care via short-term aggressive host and brood defence against conspecific females. Due to local mate competition (LMC) and broods normally being produced by a single foundress, sex ratios are female biased. Contests between adult females are, however, not normally fatal and aggression is reduced when...

Data from: Tetra-EU 1.0: a species-level trophic meta-web of European tetrapods

Luigi Maiorano, Alessandro Montemaggiori, Gentile Francesco Ficetola, Louise O'Connor & Wilfried Thuiller
Motivation Documenting potential interactions between species represents a major step to understand and predict the spatial and temporal structure of multi-trophic communities and their functioning. The metaweb concept summarises the potential trophic (and non-trophic) interactions in a given species-pool. As such, it generalises the regional species-pool of community ecology by incorporating the potential relationships between species from different trophic levels along with their functional characteristics. However, while this concept is theoretically very attractive, it has...

Analysis of RNA-seq, DNA target enrichment, and Sanger nucleotide sequence data resolves deep splits in the phylogeny of cuckoo wasps (Hymenoptera: Chrysididae)

Thomas Pauli, Karen Meusemann, Sandra Kukowka, Manuela Sann, Alexander Donath, Christoph Mayer, Jan Philip Oeyen, Yolanda Ballesteros, Alexander Berg, Eric Van Den Berghe, Hermes Escalona, Adalgisa Guglielmino, Manfred Niehuis, Massimo Olmi, Lars Podsiadlowski, Carlo Polidori, Jeroen De Rond, Paolo Rosa, Thomas Schmitt, Franco Strumia, Mareike Wurdack, Shanlin Liu, Xin Zhou, Bernhard Misof, Ralph Peters … & Oliver Niehuis
The wasp family Chrysididae (cuckoo wasps, gold wasps) comprises exclusively parasitoid and kleptoparasitic species, many of which feature a stunning iridescent coloration and phenotypic adaptations to their parasitic life style. Previous attempts to infer phylogenetic relationships among the family’s major lineages (subfamilies, tribes, genera) based on Sanger sequence data were insufficient to statistically resolve the monophyly and the phylogenetic position of the subfamily Amiseginae and the phylogenetic relationships among the tribes Allocoeliini, Chrysidini, Elampini, and...
