Transient Changes in Bacterioplankton Communities Induced by the Submarine Volcanic Eruption of El Hierro (Canary Islands)

Abstract: The submarine volcanic eruption occurring near El Hierro (Canary Islands) in October 2011 provided a unique opportunity to determine the effects of such events on the microbial populations of the surrounding waters. The birth of a new underwater volcano produced a large plume of vent material detectable from space that led to abrupt changes in the physical-chemical properties of the water column. We combined flow cytometry and 454-pyrosequencing of 16S rRNA gene amplicons (V1–V3 regions for Bacteria and V3–V5 … Show more

“…Although, we did not collect samples for microscopic observations, we believe that the high side scatter in these HNA and LNA prokaryotes are due to their association with particles. Similar cytograms of prokaryotic assemblages with HSC were recently observed associated with the discharge of vent material in stations close to a shallow submarine volcano in the Canary Islands (Ferrera et al, 2015).…”

“…Primers 28F (5′- GAGTTTGATCNTGGCTCAG-3′) and 519R (5′- GTNTTACNGCGGCKGCTG-3′) generated amplicons spanning the V1 to V3 regions of the bacterial 16S rRNA gene, and primers 341F (5′-GYGCASCAGKCGMGAAW-3′) and 958R (5′-GGACTACVSGGGTATCTAAT-3′) were used to amplify archaeal fragments spanning the V3 to V5 regions. The generated pyrosequencing data were processed using the QIIME (Quantitative Insights Into Microbial Ecology) pipeline as described in Ferrera et al [ 21 ]. Briefly, a sequence filtration step was performed before denoising sequences to reduce the impact of pyrosequencing errors.…”

“…However, heterotrophic prokaryotes increased with depth [2]. With respect to the bacterioplankton, there was an important change and groups often associated with deep-sea hydrothermal vents or sulfurrich springs were observed [31]. The increase in temperature and acidification, the decrease in oxygen and the precipitation of chemical compounds resulted in a reduction of the epipelagic stocks and a disruption of the nocturnal ascent of mesopelagic organisms [32].…”
