Data from: The role of a dominant predator in shaping biodiversity over space and time in a marine ecosystem

Kari Elsa Ellingsen, Marti J. Anderson, Nancy L. Shackell, Torkild Tveraa, Nigel G. Yoccoz & Kenneth T. Frank
1. Exploitation of living marine resources has resulted in major changes to populations of targeted species and functional groups of large-bodied species in the ocean. However, the effects of overfishing and collapse of large top predators on the broad-scale biodiversity of oceanic ecosystems remain largely unexplored. 2. Populations of the Atlantic cod (Gadus morhua) were overfished and several collapsed in the early 1990s across Atlantic Canada, providing a unique opportunity to study potential ecosystem-level effects...

Data from: Correlation of shell phenotype and local environment suggests a role for natural selection in the evolution of Placostylus snails

Eddy J. Dowle, Mary Morgan-Richards, Fabrice Brescia & Steve A. Trewick
The giant edible Placostylus snails of New Caledonia occur across a wide range of environmental conditions, from the dry southwest to the wetter central and northeastern regions. In large, slow-moving animals such as Placostylus, speciation could be assumed to be largely driven by allopatry and genetic drift as opposed to natural selection. We examined variation in shell morphology using geometric morphometrics and genetic structure within two species of Placostylus (P. fibratus, P. porphyrostomus), to determine...

Data from: Limited scope for latitudinal extension of reef corals

Paul R. Muir, Carden C. Wallace, Terence Done & J. David Aguirre
An analysis of present-day global depth distributions of reef-building corals and underlying environmental drivers contradicts a commonly held belief that ocean warming will promote tropical coral expansion into temperate latitudes. Using a global data set of a major group of reef corals, we found that corals were confined to shallower depths at higher latitudes (up to 0.6 meters of predicted shallowing per additional degree of latitude). Latitudinal attenuation of the most important driver of this...

Data from: The root of flowering plants and total evidence

Vadim V. Goremykin, Svetlana V. Nikiforova, Duccio Cavalieri, Massimo Pindo & Peter Lockhart
Support for Amborella as the sole survivor of an evolutionary lineage that is sister to all other angiosperms comes from positions in DNA multiple-sequence alignments that have a poor fit to time-reversible substitution models. These sites exhibit significant levels of homoplasy, compositional heterogeneity, and strong heterotachy. We report phylogenetic analyses with observed, randomized, and simulated data which show there is little or no expectation that these sites provide useful information for understanding relationships among basal...

Data from: Long-lasting modification of soil fungal diversity associated with the introduction of rabbits to a remote sub-Antarctic archipelago

Johan Pansu, Richard C. Winkworth, Françoise Hennion, Ludovic Gielly, Pierre Taberlet & Philippe Choler
During the late nineteenth century, Europeans introduced rabbits to many of the sub-Antarctic islands, environments that prior to this had been devoid of mammalian herbivores. The impacts of rabbits on indigenous ecosystems are well studied; notably, they cause dramatic changes in plant communities and promote soil erosion. However, the responses of fungal communities to such biotic disturbances remain unexplored. We used metabarcoding of soil extracellular DNA to assess the diversity of plant and fungal communities...

Data from: Individual repeatability in laying behaviour does not support the migratory carry-over effect hypothesis of egg-size dimorphism in Eudyptes penguins

Kyle W. Morrison
Penguins of the genus Eudyptes are unique among birds in that their first-laid A-egg is 54–85% the mass of their second-laid B-egg. Although the degree of intra-clutch egg-size dimorphism varies greatly among the seven species of the genus, obligate brood reduction is typical of each, with most fledged chicks resulting from the larger B-egg. Many authors have speculated upon why Eudyptes penguins have evolved and maintained a highly dimorphic 2-egg clutch, and why it is...

Data from: Flirtation reduces males’ fecundity but not longevity

Kambiz Esfandi, Xiong Zhao He & Qiao Wang
Theory predicts that due to limited resources males should strategically adjust their investment in reproduction and survival. Based on different conceptual framework, experimental designs and study species, many studies support while others contradict this general prediction. Using a moth Ephestia kuehniella whose adults do not feed and thus have fixed resources for their lifetime fitness, we investigated whether males adjusted their investment in various life activities under dynamic socio-sexual environment. We allowed focal males to...

Data from: Not the time or the place: the missing spatio-temporal link in publicly available genetic data

Lisa C. Pope, Libby Liggins, Jude Keyse, Silvia B. Carvalho & Cynthia Riginos
Genetic data are being generated at unprecedented rates. Policies of many journals, institutions and funding bodies aim to ensure that these data are publicly archived so that published results are reproducible. Additionally, publicly archived data can be ‘repurposed’ to address new questions in the future. In 2011, along with other leading journals in ecology and evolution, Molecular Ecology implemented mandatory public data archiving (the Joint Data Archiving Policy). To evaluate the effect of this policy,...

Data from: The effects of life history and sexual selection on male and female plumage colouration

James Dale, Cody J. Dey, Kaspar Delhey, Bart Kempenaers & Mihai Valcu
Classical sexual selection theory provides a well-supported conceptual framework for understanding the evolution and signalling function of male ornaments. It predicts that males obtain greater fitness benefits than females through multiple mating because sperm are cheaper to produce than eggs. Sexual selection should therefore lead to the evolution of male-biased secondary sexual characters. However, females of many species are also highly ornamented. The view that this is due to a correlated genetic response to selection...
