Supplementary information for integrating sequence capture and restriction-site associated DNA sequencing to resolve recent radiations of Pelagic seabirdsJoan 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...
A deep dive into fat: Investigating blubber lipidomics fingerprint of killer whales and humpback whales in northern NorwayPierre Bories, Audun Rikardsen, Pim Leonards, Aaron Fisk, Sabrina Tartu, Emma Vogel, Jenny Bytingsvik & Pierre Blevin
In cetaceans, blubber is the primary and largest lipid body reservoir. Our current understanding about lipid stores and uses in cetaceans is still limited and most studies only focused on a single narrow snapshot of the lipidome. We documented an extended lipidomics fingerprint in two cetacean species present in northern Norway during wintertime. We were able to detect 817 molecular lipid species in blubber of killer whales (Orcinus orca) and humpback whales (Megaptera novaeangliae). The...
Supplementary information for Paleoceanographic changes in the late Pliocene promoted rapid diversification in pelagic seabirdsJoan 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...
Data for: Modeling short-term energetic costs of sonar disturbance to cetaceans using high resolution foraging dataMax Czapanskiy, Matthew Savoca, William Gough, Paolo Segre, Danuta Wisniewska, David Cade & Jeremy Goldbogen
Anthropogenic noise is a pervasive and increasing source of disturbance to wildlife. Marine mammals exhibit behavioral and physiological responses to naval sonar and other sound sources. The lost foraging opportunities and elevated locomotor effort associated with sonar disturbance likely carry energetic costs, which may lead to population-level consequences. We modeled the energetic costs associated with behavioral responses using (1) empirical datasets of cetacean feeding rates and prey characteristics and (2) allometry of swimming performance and...
Variation in immunity and health in response to introduced avian malaria in an endemic Hawaiian songbirdGabrielle Names, Elizabeth Schultz, Thomas Hahn, Kathleen Hunt, Frederic Angelier, Cécile Ribout & Kirk Klasing
Emerging infectious diseases are spreading at unprecedented rates and affecting wildlife worldwide, with particularly strong effects on islands. Since the introduction of avian malaria to Hawaii a century ago, the disease has contributed to the decline and extinction of several endemic Hawaiian honeycreeper species. At low elevation, where avian malaria is prevalent, Hawaii Amakihi (Chlorodrepanis virens) honeycreeper populations have experienced strong selection by the disease and have evolved increased malaria resilience, the ability to recover...
Fine-scale spatial segregation in a pelagic seabird driven by differential use of tidewater glacier frontsPhilip Bertrand, Joël Bêty, Nigel Gilles Yoccoz, Marie-Josée Fortin, Hallvard Strøm, Harald Steen, Jack Kohler, Stephanie M. Harris, Samantha C. Patrick, Olivier Chastel, Pierre Blévin, Haakon Hop, Geir Moholdt, Joséphine Maton & Sébastien Descamps
In colonially breeding marine predators, individual movements and colonial segregation are influenced by seascape characteristics. Tidewater glacier fronts are important features of the Arctic seascape and are often described as foraging hotspots. Albeit their documented importance for wildlife, little is known about their structuring effect on arctic predator movements and space use. In this study, we tested the hypothesis that tidewater glacier fronts can influence marine bird foraging patterns and drive spatial segregation among adjacent...
1. Longitudinal studies of various vertebrate populations have demonstrated senescent declines in reproductive performance and survival probability to be almost ubiquitous. Longitudinal studies of potential underlying proximate mechanisms, however, are still scarce. 2. Due to its critical function in the maintenance of health and viability, the immune system is among the potential (mediators of) proximate mechanisms that could underlie senescence. 3. Here, we studied three innate immune parameters - hemagglutination titre, haemolysis titre and haptoglobin...
Do human infrastructures shape nest distribution in the landscape depending on individual personality in a farmland bird of prey?Juliette Rabdeau, Beatriz Arroyo, Francois Mougeot, Isabelle Badenhausser, Vincent Bretagnolle & Karine Monceau
1. Individuals´ distribution across habitats may depend on their personality. Human activities and infrastructures are critical elements of the landscape that may impact the habitat selection process. However, depending on their personality, individuals may respond differently to these unnatural elements. 2. In the present study, we first investigated whether some human infrastructures (buildings, roads and paths) shaped Montagu’s harrier nest spatial distribution in the landscape according to female personality (boldness). Second, we tested if the...
Sexual competition is increasingly recognized as an important selective pressure driving species distributions. However, few studies have investigated the relative importance of inter- vs. intrapopulation competition in relation to habitat availability and selection. To explain spatial segregation between sexes that often occurs in non-territorial and central place foragers, such as seabirds, two hypotheses are commonly used. The ‘competitive exclusion’ hypothesis states that dominant individuals should exclude subordinate individuals through direct competition whereas the ’niche divergence’...
Relationships between avian malaria resilience and corticosterone, testosterone and prolactin in a Hawaiian songbirdGabrielle Names, Jesse Krause, Elizabeth Schultz, Frédéric Angelier, Charline Parenteau, Cécile Ribout, Thomas Hahn & John Wingfield
Glucocorticoids, androgens, and prolactin regulate metabolism and reproduction, but they also play critical roles in immunomodulation. Since the introduction of avian malaria to Hawaii a century ago, low elevation populations of the Hawaii Amakihi (Chlorodrepanis virens) that have experienced strong selection by avian malaria have evolved increased resilience (the ability to recover from infection), while high elevation populations that have undergone weak selection remain less resilient. We investigated how variation in malaria selection has affected...
In a fast-changing world, polar ecosystems are threatened by climate variability. Understanding the roles of fine-scale processes, and linear and nonlinear effects of climate factors on the demography of polar species is crucial for anticipating the future state of these fragile ecosystems. While the effects of sea ice on polar marine top predators are increasingly being studied, little is known about the impacts of landfast ice (LFI) on this species community. Based on a unique...
Molecular substitution rates vary among branches and can lead to inaccurate reconstructions of evolutionary relationships and obscure the true phylogeny of affected clades. Body mass is often assumed to have a major influence on 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...
