Data from: Marine invertebrate migrations trace climate change over 450 million years

Carl J Reddin, Ádám T Kocsis & Wolfgang Kiessling
Aim: Poleward migration is a clear response of marine organisms to current global warming but the generality and geographical uniformity of this response are unclear. Marine fossils are expected to record the range shift responses of taxa and ecosystems to past climate change. However, unequal sampling (natural and human) in time and space biases the fossil record, restricting previous studies of ancient migrations to individual taxa and events. We expect that temporal changes in the...

Data from: Wear, tear and systematic repair: testing models of growth dynamics in conodonts with high-resolution imaging

Bryan Shirley, Madleen Grohganz, Michel Bestmann & Emilia Jarochowska
Conodont elements are the earliest mineralised vertebrate dental tools and the only ones capable of extensive repair. Two models of conodont growth, as well as the presence of a larval stage, have been hypothesised. We analysed normally and pathologically developed elements to test these hypotheses and identified three ontogenetic stages characterised by different anisometric growth and morphology. The distinction of these stages is independently corroborated by differences in tissue strontium content. The onset of the...

Data from: Climate change and the latitudinal selectivity of ancient marine extinctions

Carl J. Reddin, Ádám T. Kocsis & Wolfgang Kiessling
Geologically rapid climate change is anticipated to increase extinction risk non-uniformly across the Earth’s surface. Tropical species may be more vulnerable than temperate species to current climate warming because of high tropical climate velocities and reduced seawater oxygen levels. To test if rapid warming indeed preferentially increased the extinction risk of tropical fossil taxa, we combine a robust statistical assessment of latitudinal extinction selectivity (LES) with the dominant views on climate change occurring at ancient...

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...
