Ecosystem processes in Phytophthora taxon Agathis (PTA) affected Kauri stands.
Found changes in surrounding regenerative vegetation; litter fall quantity and composition. Decreased reproductive capacity of infected kauri; Differences in temperature sensitivity indicates a change in root vs microbial respiration; No differences in soil CO2 efflux suggests that roots still respire and/or accelerated microbial activity in medium-high infected sites.
