Data from: Climate shapes the geographic distribution and introgressive spread of colour ornamentation in common wall lizards

Maravillas Ruiz Minano, Geoffrey While, Weizhao Yang, Christopher Burridge, Roberto Sacchi, Marco Zuffi, Stefano Scali, Daniele Salvi & Tobias Uller
Climate can exert an effect on the strength of sexual selection, but empirical evidence is limited. Here, we tested if climate predicts the geographic distribution and introgressive spread of sexually selected male colour ornamentation across 114 populations of the common wall lizard, Podarcis muralis. Colouration was highly structured across the landscape, and did not reflect genetic differentiation. Instead, colour ornamentation was consistently exaggerated in hot and dry environments, suggesting that climate-driven selection maintains geographic variation...

Data from: Integrating local knowledge and research to refine the management of an invasive non-native grass in critically endangered grassy woodlands

Jennifer Firn, Emma Ladouceur & Josh Dorrough
1. Globally the prevalence and impact of invasive non-native plant species is increasing rapidly. Experimentally-based research aimed at supporting management is limited in its ability to keep up with this pace, partly because of the importance of understanding historical abiotic and biotic conditions. Contrastingly, landholders are in unique positions to witness species turnover in grasslands, adapt management practices in response, and learn from successes and failures. 2. This local knowledge could be crucial for identifying...

Data from: Origin and in situ diversification in Hemidactylus geckos of the Socotra Archipelago

Elena Gómez Díaz, Roberto Sindaco, Fabio Pupin, Mauro Fasola & Salvador Carranza
The Socotra Archipelago is an ancient continental fragment of Gondwanan origin and one of the most isolated landforms on Earth and a biodiversity hotspot. Yet the biogeography and evolutionary history of its endemic fauna still remain largely overlooked. We investigate the origin, tempo and mode of diversification in the Hemidactylus geckos of the Socotra Archipelago. Concatenated and multilocus species coalescent analyses of Hemidactylus from Arabia and North Africa indicate that the Hemidactylus from Socotra do...

Data from: Context-dependent expression of sexual dimorphism in island populations of the common wall lizard (Podarcis muralis)

Roberto Sacchi, Marco Mangiacotti, Stefano Scali, Marco Sannolo, Marco A. L. Zuffi, Daniele Pellitteri-Rosa, Adriana Bellati, Paolo Galeotti & Mauro Fasola
The condition-dependent sexual dimorphism model explains the evolution and maintenance of sexual dimorphism in traits targeted by sexual selection, and predicts that the magnitude of sexual dimorphism depends on the variability of individual condition, male traits being more variable than female corresponding traits. Most convincing examples concern insects, while studies among vertebrates are scanty because manipulating condition often is not possible, and the time to reach sexual maturity may be too long. Islands offer a...

Sarah Bailey, Lyndsay Brown, Marnie Campbell, João Canning-Clode, James Carlton, Nuno Castro, Paula Chainho, Farrah Chan, Joel Creed, Amelia Curd, John Darling, Paul Fofonoff, Bella Galil, Chad Hewitt, Graeme Inglis, Inti Keith, Nicholas Mandrak, Agnese Marchini, Cynthia McKenzie, Anna Occhipinti-Ambrogi, Henn Ojaveer, Larissa Pires-Teixeira, Tamara Robinson, Gregory Ruiz, Kimberley Seaward … & Aibin Zhan
Aim The introduction of aquatic non-indigenous species (ANS) has become a major driver for global changes in species biogeography. We examined spatial patterns and temporal trends of ANS detections since 1965 to inform conservation policy and management. Location Global Methods We assembled an extensive dataset of first records of detection of ANS (1965-2015) across 49 aquatic ecosystems, including the i) year of first collection, ii) population status and iii) potential pathway(s) of introduction. Data were...

Data from: Alien species spreading via biofouling on recreational vessels in the Mediterranean Sea

Aylin Ulman, Jasmine Ferrario, Aitor Forcada, Hanno Seebens, Christos Arvanitidis, Anna Occhipinti-Ambrogi & Agnese Marchini
1. Despite the Mediterranean being both a hotspot for recreational boating and for non-indigenous species (NIS), no data currently exists on the recreational boating sector’s contribution to the spread of NIS in this Sea. 2. To improve the basis for management decisions, a wide-scale sampling study on the biofouling communities of recreational vessels and marinas was undertaken. Specifically, we surveyed over 600 boat owners and sampled the same boat hulls for NIS in 25 marinas...

Data from: Network-scale effects of invasive species on spatially-structured amphibian populations

Raoul Manenti, Mattia Falaschi, Daniele Delle Monache, Silvio Marta & Francesco Ficetola
Understanding the factors affecting the dynamics of spatially-structured populations (SSP) is a central topic of conservation and landscape ecology. Invasive alien species are increasingly important drivers of the dynamics of native species. However, the impacts of invasives are often assessed at the patch scale, while their effects on SSP dynamics are rarely considered. We used long-term abundance data to test whether the impact of invasive crayfish on subpopulations can also affect the whole SSP dynamics,...

Nonlinear Optics in Photonic Crystal Cavities

Marco Clementi
Harnessing the properties of light for technological applications is perhaps the ultimate objective of photonics, whereas the generation, manipulation and detection of light in chip-based structures has an important impact both on industry and on fundamental research. The integration to semiconductor-based nanostructures makes possible the application of the photonics paradigm to compact devices which on one hand enable the processing of information at high speed, and on the other hand allow to include, onto a...

Combining conservation status and species distribution models for planning assisted colonisation under climate change

Gabriele Casazza, Thomas Abeli, Gianluigi Bacchetta, Davide Dagnino, Giuseppe Fenu, Domenico Gargano, Luigi Minuto, Chiara Montagnani, Simone Orsenigo, Lorenzo Peruzzi, Lucia Varaldo & Graziano Rossi
Effects of climate change are particularly important in the Mediterranean Biodiversity hotspot where rising temperatures and drought are negatively affecting several plant taxa, including endemic species. Assisted Colonisation (AC) represents a useful tool for reducing the effect of climate change on endemic plant species threatened by climate change. We combined SDMs for 188 taxa endemic to Italy with the IUCN red listing range loss threshold under criterion A (30%) to define: a) the number of...

Data from: Combining climate, land use change and dispersal to predict the distribution of endangered species with limited vagility

Francesca Della Rocca & Pietro Milanesi
Aim: Many rare species are dispersal-limited and minimal land use and climate changes can impact their colonization capacity. Most ecological niche models predict the distribution of species under future climate and land use change scenarios without incorporating specie-specific dispersal abilities. Here we investigated the effect of climate and land use change on low vagile species accounting for their dispersal capacity and defined accessible areas in the future. Location: Europe. Taxon: Saproxylic beetles. Methods: We used...

Trajectories of groups of Rana latastei tadpoles

Daniele Pellitteri-Rosa, Andrea Gazzola, Alessandro Balestrieri, Giovanni Scribano & Andrea Fontana
Predation is a strong driver for the evolution of prey behaviour. To properly assess the actual risk of predation, anuran tadpoles mostly rely on water-borne chemical cues, and their ability to evaluate environmental information is even more crucial when potential predators consist of unknown alien species. Behavioural plasticity, that is the capacity to express changes in behaviour in response to different environmental stimuli, is crucial to cope with predation risk. We explored the defensive behaviour...

Global sediment export based on InVEST Sediment Delivery Ratio model

Andrés F. Suarez Castro, Hawthorne L. Beyer, Caitlin D. Kuempel, Simon Linke, Pasquale Borrelli & Ove Hoegh-Guldberg
Sediment runoff from disturbed coastal catchments is a major threat to marine ecosystems. Understanding where sediments are produced and where they are delivered enables managers to design more effective strategies for improving water quality. In this context, targeted restoration of degraded terrestrial areas provides opportunities to reduce land-based runoff from coastal areas and consequently foster coral reef conservation. To do this strategically, a systematic approach is needed to identify watersheds where restoration actions will provide...

Data from: Effect of light-level geolocators on apparent survival of two highly aerial swift species

Michelangelo Morganti, Diego Rubolini, Susanne Akesson, Ana Bermejo, Javier De La Puente, Roberto Lardelli, Felix Liechti, Giovanni Boano, Erika Tomassetto, Mauro Ferri, Mario Caffi, Nicola Saino & Roberto Ambrosini
Light-level geolocators are currently widely used to track the migration of small-sized birds, but their potentially detrimental effects on survival of highly aerial species have been poorly investigated so far. We recorded capture-recapture histories of 283 common swifts Apus apus and 107 pallid swifts Apus pallidus breeding in 14 colonies in Italy, Spain, Sweden and Switzerland that were deployed with 10 different types of geolocators (‘geolocator birds’), and compared their survival with that of, respectively,...

Objective: To estimate the prevalence of Joubert syndrome (JS) in Italy applying standards of descriptive epidemiology, and to provide a molecular characterization of the described patients cohort. Methods: We enrolled all patients with a neuroradiologically confirmed diagnosis of JS and resident in Italy in 2018, and calculated age and sex prevalence, assuming a Poisson distribution. We also investigated the correlation between proband chronological age and age at diagnosis, and performed Next-Generation Sequencing (NGS) analysis on...

Data from: Brood size, telomere length, and parent-offspring color signaling in barn swallows

Alessandra Costanzo, Marco Parolini, Gaia Bazzi, Lela Khoriauli, Marco Santagostino, Cristina D. Possenti, Andrea Romano, Solomon G. Nergadze, Diego Rubolini, Elena Giulotto & Nicola Saino
Trade-offs select for optimal allocation of resources among competing functions. Parents are selected to maximize production of viable offspring by balancing between progeny number and “quality.” Telomeres are nucleoproteins, at the ends of eukaryotic chromosomes, that shorten when cells divide. Because shortening below a certain threshold depresses organismal functioning and rate of shortening depends on environmental conditions, telomeres are good candidates as mediators of trade-offs. We altered brood size of barn swallow Hirundo rustica and...

Data from: Direct and indirect causal effects of heterozygosity on fitness-related traits in Alpine ibex

Alice Brambilla, Iris Biebach, Bruno Bassano, Giuseppe Bogliani & Achaz Von Hardenberg
Heterozygosity–fitness correlations (HFCs) are a useful tool to investigate the effects of inbreeding in wild populations, but are not informative in distinguishing between direct and indirect effects of heterozygosity on fitness-related traits. We tested HFCs in male Alpine ibex (Capra ibex) in a free-ranging population (which suffered a severe bottleneck at the end of the eighteenth century) and used confirmatory path analysis to disentangle the causal relationships between heterozygosity and fitness-related traits. We tested HFCs...
