A multivariate assessment of the coral ecosystem health of two embayments on the lee of the island of Hawai‘i

A simple model capable of simulating the population dynamics of Gambierdiscus, the benthic dinoflagellate responsible for ciguatera fish poisoning

“…This result, coupled with the lower export in bloom scenarios, resulted in the increased cell abundances for the bloom outcomes. Simulation of nitrogen enrichment of the scale reported by Parsons et al (2008) resulted in a 20-fold increase in maximum abundance of Gambierdiscus by year 10 (Fig. 10A); this result is far greater than bloom scenarios simulated ( Table 4).…”

“…Cheng et al (2008) reported that temperatures have been rising at a rate of 0.028 8C yr À1 at Buoy 51001 to the west of Hawaii. Parsons et al (2008) reported that DIN concentrations in groundwater have been increasing at a rate of 1.3% yr À1 in leeward Hawaii. The temperature and DIN functions were modified to simulate these trends, and the model was run for a 10-year period for each scenario.…”

Gambierdiscus and Ostreopsis: Reassessment of the state of knowledge of their taxonomy, geography, ecophysiology, and toxicology

“…G. belizeanus and G. caribaeus could not grow at a salinity of 17, whereas G. carpenteri and G. toxicus could. As land run-off and groundwater discharges can be major sources of nutrients to reef ecosystems (e.g., Parsons et al, 2008), Gambierdiscus species capable of growing at depressed salinities could potentially tap into such nutrient resources, giving them an advantage over those species incapable of growth in the same conditions. Additionally, there may be ''niche separation'' along an inshore-offshore transect that could be (partially) driven by a salinity gradient.…”

Island ecosystem services value, land-use change, and the National New Area Policy in Zhoushan Archipelago, China

“…Since the 1990s, studies on island ecosystems have focused mainly on assessing ecosystem services and health (Parsons et al, 2008;D. Wang et al, 2014;Xu et al, 2004;Zhao et al, 2004), ecological degradation and restoration (Samways, 2000;Samways et al, 2010;Shi et al, 2012), management and planning of islands and their surrounding seas (Oost et al, 2012;Saunders, 1990;Sovacool, 2012), and the response of island ecosystems to anthropogenic effects (Angeler & Alvarez-Cobelas, 2005;Lin et al, 2013;Wang et al, 2010).…”
