Data from: Body shape convergence driven by small size optimum in marine angelfishes

Bruno Frédérich, Francesco Santini, Nicolai Konow, Joseph Schnitzler, David Lecchini & Michael E. Alfaro
Convergent evolution of small body size occurs across many vertebrate clades and may reflect an evolutionary response to shared selective pressures. However it remains unclear if other aspects of phenotype undergo convergent evolution in miniaturized lineages. Here we present a comparative analysis of body size and shape evolution in marine angelfishes (Pomacanthidae), a reef fish family characterized by repeated transitions to small body size. We ask if lineages that evolve small sizes show convergent evolution...

Parentage analyses identify local dispersal events and sibling aggregations in a natural population of Millepora hydrocorals, a free-spawning marine invertebrate

Caroline Dubé, Emilie Boissin, Alexandre Mercière & Serge Planes
Dispersal is a critical process for the persistence and productivity of marine populations. For many reef species, there is increasing evidence that local demography and self-recruitment have major consequences on their genetic diversity and adaptation to environmental change. Yet empirical data of dispersal patterns in reef-building species remain scarce. Here, we document the first genetic estimates of self-recruitment and dispersal distances in a free-spawning marine invertebrate, the hydrocoral Millepora platyphylla. Using twelve microsatellite markers, we...

Guadeloupe Snails Metacommunity

Maxime Dubart, Jean-Pierre Pointier, Philippe Jarne & Patrice David
Metacommunity structure reflects the interplay of various processes, including niche filtering, extinction/colonization, and interspecific interactions. Spatial patterns of species distributions are often analyzed to infer these processes. However, such inferences rely on often unrealistic equilibrium assumptions, and remain ambiguous, as different processes can produce similar patterns. Temporal data may improve these inferences. For example, stochastic species turnover may occur in local communities, while, on the long run, temporal changes are kept within limits set by...

First use of acoustic calls to distinguish cryptic fish species: Dascyllus aruanus complex as a case study

Eric Parmentier, Eric Parmentier, Robin Scalbert, Xavier Raick, Camille Gache, Bruno Frédérich, Frederic Bertucci & David Lecchini
From a practical point of view, the determination of species in the wild is based on their phenotypes. Consequently, many species remain unknown because they are visually indistinguishable from described species. Although molecular methods and advances in bioacoustical analysis have been extensively used to uncover cryptic species, the combination of both methodologies is still rare and concerns only some terrestrial taxa such as insects, bats, frogs and birds. In this study, we aim to determine...

Data from: Genetic connectivity of Lionfish (Pterois volitans) in marine protected areas of the Gulf of Mexico and Caribbean Sea

Irán Andira Guzmán Mendez, Renata Rivera Madrid, Serge Planes, Emilie Boissin, Aldo Croquer, Esteban Agudo, Carlos González Gandara, Horacio Pérez España, Ana Giro Petersen, Jenny Luque, María Del Carmen García-Rivas, Margarita Aguilar Espinosa, Jimmy Arguelles Jiménez & Jesús Ernesto Arias González
Lionfish (Pterois volitans) have rapidly invaded the tropical Atlantic and spread across the wider Caribbean in a relatively short period of time. Because of its high invasion capacity, we used it as a model to identify the connectivity among nine marine protected areas (MPAs) situated in four countries in the Gulf of Mexico and the Caribbean Sea.This study provides evidence of local genetic differentiation of P. volitansin the Gulf of Mexico and the Caribbean Sea.A...

Data from: Coalescence times, life history traits and conservation concerns: an example from four coastal shark species from the Indo-Pacific

Pierre Lesturgie, Serge Planes & Stefano Mona
Dispersal abilities play a crucial role in shaping the extent of population genetic structure, with more mobile species being panmictic over large geographic ranges and less mobile ones organized in meta-populations exchanging migrants to different degrees. In turn, population structure directly influences the coalescence pattern of the sampled lineages, but the consequences on the estimated variation of the effective population size (Ne) over time obtained by means of unstructureddemographic models remain poorly understood. However, this...

Data from: Comparative phylogeography of three host sea anemones in the Indo-Pacific

Pablo Saenz-Agudelo, Madeleine Emms, Emily Giles, Remy Gatins, Gerrit Nanninga, Anna Scott, Jean Paul Hobbs, Ashley Frisch, Suzanne Mills, Ricardo Beldade & Michael Berumen
Aim The mutualistic relationship between anemones and anemonefishes is one of the most iconic examples of symbiosis. However, while anemonefishes have been extensively studied in terms of genetic connectivity, such information is lacking entirely for host sea anemones. Here, we provide the first information on the broad-scale population structure and phylogeographic patterns of three species of host sea anemone, Heteractis magnifica, Stichodactyla mertensii, and Entacmaea quadricolor. We evaluate if there is concordance in genetic structure...

Data from: A worldwide perspective on the population structure and genetic diversity of bottlenose dolphins (Tursiops truncatus) in New Zealand

Gabriela Tezanos-Pinto, Charles S Baker, Kirsty Russell, Karen Martien, Robin Baird, Alistair Hutt, Gregory Stone, Antonio A Mignucci-Giannoni, Susana Caballero, Tetsuya Endo, Shane Lavery, Marc Oremus, Carlos Olavarria & Claire Garrigue
Bottlenose dolphins (Tursiops truncatus) occupy a wide range of coastal and pelagic habitats throughout tropical and temperate waters worldwide. In some regions, "inshore" and "offshore" forms or ecotypes differ genetically and morphologically, despite no obvious boundaries to interchange. Around New Zealand, bottlenose dolphins inhabit 3 coastal regions: Northland, Marlborough Sounds, and Fiordland. Previous demographic studies showed no interchange of individuals among these populations. Here, we describe the genetic structure and diversity of these populations using...

Data from: Concede or clash? Solitary sharks competing for food assess rivals to decide.

Pierpaolo F. Brena, Johann Mourier, Serge Planes & Eric E. Clua
To adapt to their environment, organisms can either directly interact with their surroundings or use social information, namely information provided by neighbouring individuals. Social information relates to the external features of surrounding peers, and little is known about its use by solitary species. Here, we investigated the use of social cues in a solitary marine predator by creating artificial aggregations of free-ranging sicklefin lemon sharks (Negaprion acutidens). Using a novel monitoring protocol, we analysed both...

Data from: Climate impacts on the ocean are making the Sustainable Development Goals a moving target traveling away from us

Gerald G. Singh, Nathalie Hilmi, Joey R. Bernhardt, Andres M. Cisneros Montemayor, Madeline Cashion, Yoshitaka Ota, Sevil Acar, Jason M. Brown, Richard Cottrell, Salpie Djoundourian, Pedro C. Gonzalez-Espinosa, Vicky Lam, Nadine Marshall, Barbara Neumann, Nicolas Pascal, Gabriel Reygondeau, Joacim Rocklov, Alain Safa, Laura R. Virto & William Cheung
1. Climate change is impacting marine ecosystems and their goods and services in diverse ways, which can directly hinder our ability to achieve the Sustainable Development Goals, set out under the 2030 Agenda for Sustainable Development. 2. Through expert elicitation and a literature review, we find that most climate change effects have a wide variety of negative consequences across marine ecosystem services, though most studies have highlighted impacts from warming and consequences to marine species....
