Posterior cervical brown fat and CXCL14 levels in the first year of life: sex differences and association with adiposity

Lourdes Ibanez & Francesc Villarroya
Context: Brown adipose tissue (BAT) is particularly abundant in neonates but its association with measures of adiposity and metabolic health in early infancy is poorly delineated. Besides sustaining non-shivering thermogenesis, BAT secretes brown adipokines that act on systemic metabolism. The chemokine CXCL14 has been identified as a brown adipokine in experimental studies. Objective: To determine the relationships among BAT activity, adiposity and circulating CXCL14 levels in the first year of life in girls and boys....

Supplementary information for integrating sequence capture and restriction-site associated DNA sequencing to resolve recent radiations of Pelagic seabirds

Joan Ferrer-Obiol, Helen F. James, R. Terry Chesser, Vincent Bretagnolle, Jacob González-Solís, Julio Rozas, Marta Riutort & Andreanna J. Welch
The diversification of modern birds has been shaped by a number of radiations. Rapid diversification events make reconstructing the evolutionary relationships among taxa challenging due to the convoluted effects of incomplete lineage sorting (ILS) and introgression. Phylogenomic datasets have the potential to detect patterns of phylogenetic incongruence, and to address their causes. However, the footprints of ILS and introgression on sequence data can vary between different phylogenomic markers at different phylogenetic scales depending on factors...

Energy limitation or sensitive predators? Trophic and non-trophic impacts of wastewater pollution on stream food webs

Jordi-René Mor, Isabel Muñoz, Sergi Sabater, Lluís Zamora & Albert Ruhi
Impacts of environmental stressors on food webs are often difficult to predict because trophic levels can respond in divergent ways, and biotic interactions may dampen or amplify responses. Here we studied food-web level impacts of urban wastewater pollution, a widespread source of degradation that can alter stream food webs via top-down and bottom-up processes. We selected ten pairs of sampling locations (i.e., twenty sites total) in ten small-to-medium tributaries of the Ebro River (NE Iberian...

Forest resilience to global warming is strongly modulated by local-scale topographic, microclimatic and biotic conditions

Jofre Carnicer
Resilience of endangered rear edge populations of cold-adapted forests in the Mediterranean basin is increasingly altered by extreme heatwave and drought pressures. It remains unknown, however, whether microclimatic variation in these isolated forests could ultimately result in large intra-population variability in the demographic responses, allowing the coexistence of contrasting declining and resilient trends across small topographic gradients. Multiple key drivers promoting spatial variability in the resilience of rear edge forests remain largely unassessed, including amplified...

The concurrent assessment of agronomic, ecological, and environmental variables enables better choice of agroecological service crop termination management

David Navarro-Miró, José M. Blanco-Moreno, Corrado Ciaccia, Elena Testani, Ileana Iocola, Laura Depalo, Giovanni Burgio, Hanne Lakkenborg Kristensen, Margita Hefner, Kalvi Tamm, Ingrid Bender, Alessandro Persiani, Mariangela Diacono, Francesco Montemurro, Koen Willekens, Hélène Védie, Martina Bavec, Martina Robačer, Donatienne Arlotti, Pauline Deltour, Stefaan De Neve, Mesfin Tsegaye Gebremikael, Lourdes Chamorro, Berta Caballero-López, Alejandro Pérez-Ferrer … & F. Xavier Sans
1. Although organic farming was originally promoted as an alternative farming system to address agronomic, environmental, and ecological issues, its conventionalisation has led to an intensification and specialisation of production. In light of this, several studies have questioned the environmental benefits of organic farming as well as its agronomic viability. Thus, there is a need to improve organic vegetable systems to reduce their environmental impact without affecting their productivity. To tackle this challenge, European farmers...

A novel mitochondrial Kv1.3-caveolin axis controls cell survival and apoptosis

Antonio Felipe, Jesusa Capera, Mireia Pérez-Verdaguer, Roberta Peruzzo, María Navarro-Pérez, Juan Martínez-Pinna, Armando Alberola-Die, Andrés Morales, Luigi Leanza & Ildiko Szabo
The voltage-gated potassium channel Kv1.3 plays an apparent dual physiological role by participating in activation and proliferation of leukocytes as well as promoting apoptosis in several types of tumor cells. Therefore, Kv1.3 is considered a potential pharmacological target for immunodeficiency and cancer. Different cellular locations of Kv1.3, at the plasma membrane or the mitochondria, could be responsible for such duality. While plasma membrane Kv1.3 facilitates proliferation, the mitochondrial channel modulates apoptotic signaling. Several molecular determinants...

Double-tagging scores of seabirds reveals that light-level geolocator accuracy is limited by species idiosyncrasies and equatorial solar profiles

Luke Halpin, Jeremy Ross, Raül Ramos, Rowan Mott, Nicholas Carlile, Nick Golding, José Manuel Reyes-González, Teresa Militão, Fernanda De Felipe, Zuzana Zajková, Marta Cruz Flores, Sarah Saldanha, Virginia Morera-Pujol, Leia Navarro-Herrero, Laura Zango, Jacob Gonzalez-Solis & Rohan Clarke
Light-level geolocators are popular bio-logging tools, with advantageous sizes, longevity, and affordability. Biologists tracking seabirds often presume geolocator spatial accuracies between 186-202 km from previously-innovative, yet taxonomically, spatially, and computationally limited, studies. Using recently developed methods, we investigated whether assumed uncertainty norms held across a larger-scale, multispecies study. We field-tested geolocator spatial accuracy by synchronously deploying these with GPS loggers on scores of seabirds across five species and 11 Mediterranean Sea, East Atlantic and South...

Diversity mediates the responses of invertebrate density to duration and frequency of rivers’ annual drying regime

Rebeca Arias-Real, Cayetano Gutiérrez-Cánovas, Margarita Menéndez, Verónica Granados & Isabel Muñoz
Predicting the impacts of global change on highly dynamic ecosystems requires a better understanding of how communities respond to disturbance duration, frequency and timing. Intermittent rivers and ephemeral streams are dynamic ecosystems that are recognized as the most common fluvial ecosystem globally. The complexity of the drying process can give rise to different annual and antecedent hydrological conditions, but their effect on aquatic communities remains unclear. Here, using aquatic invertebrates from 33 streams across a...

Predators like it hot: Thermal mismatch in a predator-prey system across an elevational tropical gradient

Pol Pintanel, Pol Pintanel, Miguel Tejedo, Sofia Salinas-Ivanenko, Phillip Jervis & Andrés Merino-Viteri
Climate change may have dramatic consequences for communities through both direct effects of peak temperatures upon individual species and through interspecific mismatches in thermal sensitivities of interacting organisms which mediate changes in interspecific interactions (i.e. predation). Despite this, there is a paucity of information upon the patterns of spatial physiological sensitivity of interacting species (at both landscape and local scales) which could ultimately influence geographical variation in the effects of climate change upon community processes....

Physiology and acclimation potential are tuned with phenology in larvae of a prolonged breeder amphibian

Urtzi Enriquez-Urzelai, Alfredo G. Nicieza, Albert Montori, Gustavo A. Llorente & Miren Bego Urrutia
Due to the speed of climate changes, rapid buffering mechanisms such as phenotypic plasticity – which may depend on breeding phenology – could be key to avoid extinction. The links between phenology and plasticity, however, remain understudied. Here we explored the matching between phenology and the thermal sensitivity of standard (SMR) and routine metabolic rates (RMR), metabolic scope (i.e. the difference between RMR and SMR), survival and growth-development trajectories in larvae of a prolonged breeder...

Supplementary information for Paleoceanographic changes in the late Pliocene promoted rapid diversification in pelagic seabirds

Joan Ferrer Obiol, Helen F. James, R. Terry Chesser, Vincent Bretagnolle, Jacob González-Solís, Julio Rozas, Andreanna J. Welch & Marta Riutort
Aim: Paleoceanographic changes can act as drivers of diversification and speciation, even in highly mobile marine organisms. Shearwaters are a group of globally distributed and highly mobile pelagic seabirds. Despite a recent well resolved phylogeny, shearwaters have controversial species limits, and show periods of both slow and rapid diversification. Here, we explore the role of paleoceanographic changes on the diversification and speciation in these highly mobile pelagic seabirds. We investigate shearwater biogeography and the evolution...

Source data and code for: Climate change transforms the functional identity of Mediterranean coralligenous assemblages

Daniel Gómez-Gras, Cristina Linares, Maria Dornelas, Joshua S. Madin, Viviana Brambilla, Jean-Baptiste Ledoux, Nathaniel Bensoussan, Paula López-Sendino & Joaquim Garrabou
We used five long-term (>10 years) records of Mediterranean coralligenous assemblages in a multi-taxa, trait-based analysis to investigate MHW-driven changes in functional structure. We show that, despite stability in functional richness (i.e., the range of species functional traits), MHW-impacted assemblages experienced long-term directional changes in functional identity (i.e., their dominant trait values). Declining traits included large sizes, long lifespans, arborescent morphologies, filter feeding strategies or calcified skeletons. These traits, which were mostly supported by few...

Effects of episodic nutrients enrichments on P-limited planktonic communities: Lake Redon ENEX 2013 experiment

Jordi Catalan, Marisol Felip, Pau Giménez-Grau, Aitziber Zufiaurre, Lluis Camarero & Sergi Pla-Rabés
Planktonic communities are naturally subjected to episodic nutrient enrichments that may stress or redress the imbalances in limiting nutrients. Human-enhanced atmospheric nitrogen deposition has caused profound N:P imbalance in many remote oligotrophic lakes in which phosphorus has largely become limiting. These lakes offer an opportunity to investigate the planktonic community response to nutrient fluctuations in P-limited conditions. The ENEX experiment in Lake Redon (Pyrenees), performed during August 2013, aimed to investigate the structural and stoichiometric...

Disentangling responses to natural stressor and human impact gradients in river ecosystems across Europe

Rachel Stubbington, Romain Sarremejane, Alex Laini, Núria Cid, Zoltán Csabai, Judy England, Antoni Munné, Tom Aspin, Núria Bonada, Daniel Bruno-Collados, Sophie Cauvy-Fraunie, Richard Chadd, Claudia Dienstl, Pau Fortuño, Wolfram Graf, Cayetano Gutiérrez-Cánovas, Andy House, Ioannis Karaouzas, Eleana Kazila, Andrés Millán, Maria Morais, Petr Pařil, Alex Pickwell, Marek Polášek, David Sánchez-Fernández … & Thibault Datry
1. Rivers are dynamic ecosystems in which both human impacts and climate-driven drying events are increasingly common. These anthropogenic and natural stressors interact to influence the biodiversity and functioning of river ecosystems. Disentangling ecological responses to these interacting stressors is necessary to guide management actions that support ecosystems adapting to global change. 2. We analysed the independent and interactive effects of human impacts and natural drying on aquatic invertebrate communities—a key biotic group used to...

Data from: The leaf economic and plant size spectra of European forest understory vegetation

Josep Padullés Cubino, Idoia Biurrun, Gianmaria Bonari, Tatiana Braslavskaya, Xavier Font, Ute Jandt, Florian Jansen, Valerijus Rašomavičius, Wolfgang Willner & Milan Chytrý
Forest understories play a vital role in ecosystem functioning and the provision of ecosystem services. However, the extent to which environmental conditions drive dominant ecological strategies in forest understories at the continental scale remains understudied. Here, we used ~29,500 forest vegetation plots sampled across Europe and classified into 25 forest types to explore the relative role of macroclimate, soil pH, and tree canopy cover in driving abundance-weighted patterns in the leaf economic spectrum (LES) and...

Substitution rate variation in a robust procellariiform seabird phylogeny is not solely explained by body mass, flight efficiency, population size or life history traits

Andrea Estandia, Terry Chesser, Helen James, Max Levy, Joan Ferrer-Obiol, Vincent Bretagnolle, Jacob González-Solís & Andreanna Welch
Molecular substitution rates vary among branches, which can lead to inaccurate reconstructions of evolutionary relationships and obscure the true phylogeny of affected clades. Body mass is often assumed to be a major driver of substitution rate, though other factors such as population size, life history traits, and flight demands are also thought to have an influence. Birds of the order Procellariiformes—which encompasses petrels, storm-petrels and albatrosses—show a striking 900-fold difference in body mass between the...

Epiphytic diatom community structure and richness is determined by macroalgal host and location in the South Shetland Islands (Antarctica)

Andrea Burfeid-Castellanos, Rafael P. Martín-Martín, Michael Kloster, Carlos Angulo-Preckler, Conxita Avila & Bánk Beszteri
The marine waters around the South Shetland Islands are paramount in the primary production of this Antarctic ecosystem. With the increasing effects of climate change and the annual retreat of the ice shelf, the importance of macroalgae and their diatom epiphytes in primary production also increases. The relationships and interactions between these organisms have scarcely been studied in Antarctica, and even less in the volcanic ecosystem of Deception Island, which can be seen as a...
