Data from: In vivo dynamics of skeletal muscle Dystrophin in zebrafish embryos revealed by improved FRAP analysis

Dystrophin forms an essential link between sarcolemma and cytoskeleton, perturbation of which causes muscular dystrophy. We analysed Dystrophin binding dynamics in vivo for the first time. Within maturing fibres of host zebrafish embryos, our analysis reveals a pool of diffusible Dystrophin and complexes bound at the fibre membrane. Combining modelling, an improved FRAP methodology and direct semi-quantitative analysis of bleaching suggests the existence of two membrane-bound Dystrophin populations with widely differing bound lifetimes: a stable,...

Data from: Coral feeding on microalgae assessed with molecular trophic markers

Miguel C. Leal, Christine Ferrier-Pagès, Ricardo Calado, Megan E. Thompson, Marc E. Frischer & Jens C. Nejstgaard
Herbivory in corals, especially for symbiotic species, remains controversial. To investigate the capacity of scleractinian and soft corals to capture microalgae, we conducted controlled laboratory experiments offering five algal species: the cryptophyte Rhodomonas marina, the haptophytes Isochrysis galbana and Phaeocystis globosa, and the diatoms Conticribra weissflogii and Thalassiosira pseudonana. Coral species included the symbiotic soft corals Heteroxenia fuscescens and Sinularia flexibilis, the asymbiotic scleractinian coral Tubastrea coccinea, and the symbiotic scleractinian corals Stylophora pistillata, Pavona...

Data from: New insights into carbon acquisition and exchanges within the coral-dinoflagellate symbiosis under NH4+ and NO3- supply

Leïla Ezzat, Jean-François Maguer, Renaud Grover & Christine Ferrier-Pagès
Anthropogenic nutrient enrichment affects the biogeochemical cycles and nutrient stoichiometry of coastal ecosystems and is often associated with coral reef decline. However, the mechanisms by which dissolved inorganic nutrients, and especially nitrogen forms (ammonium versus nitrate) can disturb the association between corals and their symbiotic algae are subject to controversial debate. Here, we investigated the coral response to varying N : P ratios, with nitrate or ammonium as a nitrogen source. We showed significant differences...

Data from: A remote-controlled observatory for behavioural and ecological research: a case study on emperor penguins

Sebastian Richter, Richard C. Gerum, Werner Schneider, Ben Fabry, Céline Le Bohec & Daniel P. Zitterbart
1. Long-term photographic recordings of animal populations provide unique insights in ecological and evolutionary processes. However, image acquisition at remote locations under harsh climatic conditions is highly challenging. 2. We present a robust, energetically self-sufficient and remote-controlled observatory designed to operate year-round in the Antarctic at temperatures below -50 °C and wind speeds above 150 km/h. The observatory is equipped with multiple overview cameras and a high resolution steerable camera with a telephoto lens for...

Data from: Nutrient starvation impairs the trophic plasticity of reef-building corals under ocean warming

Leïla Ezzat, Jean-François Maguer, Renaud Grover, Cécile Rottier, Pascale Tremblay, Christine Ferrier-Pagès & Jean‐François Maguer
1) Global warming of the world’s oceans is driving reef-building corals towards their upper thermal limit, inducing bleaching, nutrient starvation and mortality. In addition, corals are predicted to experience large fluctuations in seawater nutrient concentrations, following water column stratification or eutrophication problems, which can further alter their nutritional capacities and ultimately their resilience to global change. 2) We investigated the effect of thermal stress and dissolved inorganic nutrient (DINUT) availability on the auto- and heterotrophic...

Raw acceleration, gyroscope and depth profiles associated with the observed behaviours of free-ranging immature green turtles in Martinique

Lorene Jeantet, Victor Planas-Bielsa, Simon Benhamou, Sébastien Geiger, Jordan Martin, Flora Siegwalt, Pierre Lelong, Julie Gresser, Denis Etienne, Gaëlle Hiélard, Alexandre Arque, Sidney Regis, Nicolas Lecerf, Cédric Frouin, Abdelwahab Benhalilou, Céline Murgale, Thomas Maillet, Lucas Andreani, Guilhem Campistron, Hélène Delvaux, Christelle Guyon, Sandrine Richard, Fabien Lefebvre, Nathalie Aubert, Caroline Habold … & Damien Chevallier
The identification of sea turtle behaviours is a prerequisite to predicting the activities and time-budget of these animals in their natural habitat over long term. However, this is hampered by a lack of reliable methods that enable the detection and monitoring of certain key behaviours such as feeding. This study proposes a combined approach that automatically identifies the different behaviours of free-ranging sea turtles through the use of animal-borne multi-sensor recorders (accelerometer, gyroscope and time-depth...

Contextual variations in calls of two non-oscine birds: the blue petrel and the Antarctic prion

Charlène Gémard, Víctor Planas-Bielsa, Francesco Bonadonna & Thierry Aubin
Bird vocalizations are critical cues in social interactions as they convey temporary information varying with the social context, e.g. the signaler motivation when facing a rival or a potential mate. To date, literature mainly focuses on learning birds. Burrowing petrels (Procellariidae) are non-learning birds with a limited vocal repertoire. Bachelor males communicate with conspecifics with a single call emitted in three situations: in absence of a certain auditory (spontaneous calls), towards females (female-directed calls) and...
