Data from: A novel report of hatching plasticity in the phylum Echinodermata

Anne Frances Armstrong, Holly Nicole Blackburn & Jonathan D. Allen
Hatching plasticity occurs in response to a wide range of stimuli across many animal taxa, including annelids, arthropods, mollusks, and chordates. Despite the prominence of echinoderms in developmental biology and more than 100 years of detailed examination of their development under a variety of conditions, environmentally cued hatching plasticity has never been reported in the phylum Echinodermata. Here we report plasticity in the timing and stage of hatching of embryos of the sand dollar Echinarachnius...

Data from: Influence of natural and novel organic carbon sources on denitrification in forest, degraded urban, and restored streams

Tamara A. Newcomer, Sujay S. Kaushal, Paul M. Mayer, Amy R. Shields, Elizabeth A. Canuel, Peter M. Groffman & Arthur J. Gold
Organic carbon is important in regulating ecosystem function, and its source and abundance may be altered by urbanization. We investigated shifts in organic carbon quantity and quality associated with urbanization and ecosystem restoration, and its potential effects on denitrification at the riparian–stream interface. Field measurements of streamwater chemistry, organic carbon characterization, and laboratory-based denitrification experiments were completed at two forested, two restored, and two unrestored urban streams at the Baltimore Long-Term Ecological Research site, Maryland,...

Data from: Selective bird predation on the peppered moth: the last experiment of Michael Majerus

Laurence M. Cook, Bruce S. Grant, Ilik J. Saccheri & James Mallet
Colour variation in the peppered moth Biston betularia was long accepted to be under strong natural selection. Melanics were believed to be fitter than pale morphs because of lower predation at daytime resting sites on dark, sooty bark. Melanics became common during the industrial revolution, but since 1970 there has been a rapid reversal, assumed to have been caused by predators selecting against melanics resting on today's less sooty bark. Recently, these classical explanations of...
