The Theory of Island Biogeography predicts that area and age explain
species richness patterns (or alpha diversity) in insular habitats. Using
a unique natural phenomenon, pumice rafting, we measured the influence of
area, age and oceanic climate on patterns of species richness. Pumice
rafts are formed simultaneously when submarine volcanoes erupt, the pumice
clasts break-up irregularly, forming irregularly shaped pumice stones
which while floating through the ocean are colonised by marine biota. We
analyse two eruption events and more than 5000 pumice clasts collected
from 29 sites and three climatic zones. Overall the older and larger
pumice clasts held more species. Pumice clasts arriving in tropical and
subtropical climates showed this same trend, where in temperate locations
species richness (alpha diversity) increased with area but decreased with
age. Beta diversity analysis of the communities forming on pumice clasts
that arrived in different climatic zones showed that tropical and
subtropical clasts transported similar communities while species
composition on temperate clasts differed significantly from both tropical
and subtropical arrivals. Using these thousands of insular habitats, we
find strong evidence that area and age but also climatic conditions
predict the fundamental dynamics of species richness colonising pumice
clasts.
Combined_data_Home_and_Havre_Dryad_Eleanor_Velasquez_6_3_18This file
contains data collected on the presence of marine invertebrates attached
to floating pumice which washed ashore on the east coast of Australia and
islands in the Pacific. This occurred following two marine volcano
eruption events. The Home reef eruption occurred in 2006 and the Havre in
2012. Both events were used so that we could compare and contrast the
differences and similarities between the two.
