Note
Coral reefs off southeast Florida have experienced an unprecedented succession of invasive chlorophyte blooms over the past two decades, most recently the non-native Caulerpa brachypus f. parvifolia. To better understand the ecology and nutrition of the C. brachypus invasion, we monitored benthic cover, water column dissolved inorganic nutrients, tissue C:N:P ratios and stable nitrogen isotopes (d15N) of C. brachypus and native chlorophytes (Caulerpa racemosa, Caulerpa verticillata, Caulerpa mexicana, Codium isthmocladum) quarterly at two reef sites – the Princess Anne (PA) and North Colonel’s Ledge (NCL) – in 2003–2004.
