Nitrogen stable isotope data from soil, leaf and spider samples collected from invaded, never invaded and eradicated islands around New Zealand's north island; and associated R code used to investigate the use of stable isotope analysis as a post-eradication ecosystem function assessment tool.
Seasonal patterns in the in situ ecophysiology of the common habitat-forming seaweeds Ecklonia radiata, Phyllospora comosa, and Macrocystis pyrifera were investigated at different latitudes and depths in southeastern Australia. We used multiple performance indicators (photosynthetic characteristics, pigment content, chemical composition, stable isotopes, nucleic acids) to assess the ecophysiology of seaweeds near the northern and southern margins of their range, along a depth gradient (E. radiata only), over a two year period (September 2010 – August 2012).
