Data from: Linking oceanographic conditions, migratory schedules and foraging behaviour during the non‐breeding season to reproductive performance in a long‐lived seabird

Marine Desprez, Stephanie Jenouvrier, Christophe Barbraud, Karine Delord & Henri Weimerskirch
1. Studies of the mechanisms underlying climate-induced population changes are critically needed to better understand and accurately predict population responses to climate change. Long-lived migratory species might be particularly vulnerable to climate change as they are constrained by different climate conditions and energetic requirements during the breeding and non-breeding seasons. Yet, most studies primarily focus on the breeding season of these species lifecycle. Environmental conditions experienced in the non-breeding season may have downstream effects on...

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: Reproductive success of a keystone herbivore is more variable and responsive to climate in habitats with lower resource diversity

David T. Iles, Robert F. Rockwell, Dave N. Koons & David N. Koons
1. The effects of climate on wild populations are often channeled through species interactions. Population responses to climate variation can therefore differ across habitats, owing to variation in the biotic community. Theory predicts that consumer demography should be less variable and less responsive to climate in habitats with greater resource diversity. 2. We tested these predictions using a long-term study of breeding lesser snow geese along the western coast of Hudson Bay, Manitoba, Canada. Reproductive...

Supplementary Information: Antibiotic resistance in Vibrio-like bacteria is common on Cape Cod, MA beaches

Megan May & Rebecca J. Gast
Antibiotic resistance (AR) is a natural process, enhanced by anthropogenic antibiotic use. Natural environments, like the ocean, act as reservoirs of resistance; but until recently, little research has examined their dynamics. Six beaches on Cape Cod, MA, with varying human impacts, were sampled over one year on nine occasions. Vibrio-like bacteria were isolated from wet sand, dry sand, and water from each beach and tested for sensitivity to five antibiotics (amoxicillin/clavulanic acid, ciprofloxacin, doxycycline, oxytetracycline,...

Data from: The evolution of marine larval dispersal kernels in spatially structured habitats: analytical models, individual-based simulations, and comparisons with empirical estimates

Allison K. Shaw, Cassidy C. D'Aloia & Peter M. Buston
Understanding the causes of larval dispersal is a major goal of marine ecology, yet most research focuses on proximate causes. Here, we ask how ultimate, evolutionary causes affect dispersal. Building on Hamilton and May's 1977 classic paper (``Dispersal in stable habitats"), we develop analytic and simulation models for the evolution of dispersal kernels in spatially structured habitats. First, we investigate dispersal in a world without edges and find that most offspring disperse as far as...

Data from: Climate change and functional traits affect population dynamics of a long-lived seabird

Stephanie Jenouvrier, Marine Desprez, Rémi Fay, Christophe Barbraud, Henri Weimerskirch, Karine Delord & Hal Caswell
1. Recent studies unravelled the effect of climate changes on populations through their impact on functional traits and demographic rates in terrestrial and freshwater ecosystems, but such understanding in marine ecosystems remains incomplete. 2. Here, we evaluate the impact of the combined effects of climate and functional traits on population dynamics of a long-lived migratory seabird breeding in the southern ocean: the black-browed albatross (Thalassarche melanophris, BBA). We address the following prospective question: ''Of all...

Data from: How do baleen whales stow their filter? A comparative biomechanical analysis of baleen bending

Alexander J. Werth, Diego Rita, Michael V. Rosario, Michael J. Moore & Todd L. Sformo
Bowhead and right whale (balaenid) baleen filtering plates, longer in vertical dimension (3-4+ m) than the closed mouth, presumably bend during gape closure. This has not been observed in live whales, even with scrutiny of videorecorded feeding sequences. To determine what happens to baleen as gape closes, we conducted an integrative, multifactorial study including materials testing, functional (flow tank and kinematic) testing, and histological examination. We measured baleen bending properties along the dorsoventral length of...
