Data from: A tale of the ciliate tail: investigation into the adaptive significance of this sub-cellular structure

Brad J. Gemmell, Houshuo Jiang & Edward J. Buskey
Ciliates can form an important link between the microbial loop and higher trophic levels primarily through consumption by copepods. This high predation pressure has resulted in a number of ciliate species developing rapid escape swimming behaviour. Several species of these escaping ciliates also possess a long contractile tail for which the functionality remains unresolved. We use high-speed video, specialized optics and novel fluid visualization tools to evaluate the role of this contractile appendage in two...

Data from: Extreme climate events and individual heterogeneity shape life-history traits and population dynamics

Stéphanie Jenouvrier, Clara Péron & Henri Weimerskirch
Extreme climatic conditions and their ecological impacts are currently emerging as critical features of climate change. We studied extreme sea ice condition (ESIC) and found it impacts both life-history traits and population dynamics of an Antarctic seabird well beyond ordinary variability. The Southern Fulmar (Fulmarus glacialoides) is an ice-dependent seabird, and individuals forage near the ice edge. During an extreme unfavorable year (when sea ice area is reduced and distance between ice edge and colony...

Data from: Testing the depth-differentiation hypothesis in a deepwater octocoral

Andrea M. Quattrini, Iliana B. Baums, Timothy M. Shank, Cheryl L. Morrison & Erik E. Cordes
The depth-differentiation hypothesis proposes that the bathyal region is a source of genetic diversity and an area where there is a high rate of species formation. Genetic differentiation should thus occur over relatively small vertical distances, particularly along the upper continental slope (200–1000 m) where oceanography varies greatly over small differences in depth. To test whether genetic differentiation within deepwater octocorals is greater over vertical rather than geographical distances, Callogorgia delta was targeted. This species...
