Transport of invasive microorganisms

The objectives of his project are to investigate the vectors and timing of microbiological invasions and the subsequent dispersal of these non-native organisms due to sediment transport. We will attempt to confirm the identification of specific invasives encountered with molecular sequencing, monitor the spread of the invading populations through their recent distribution and the historic...

Arrival and expansion of the invasive foraminifera Trochammina hadai Uchio in Padilla Bay, Washington

Trochammina hadai Uchio, a benthic foraminifera native to Japanese estuaries, was first identified as an invasive in 1995 in San Francisco Bay and later in 16 other west coast estuaries. To investigate the timing of the arrival and expansion of this invasive species in Padilla Bay, Washington, we analyzed the distribution of foraminifera in two surface samples collected in 1971, in nine surface sa
