(Journal article; Peer reviewed, 2007-12-13)The search for effective and long-term solutions to the problems caused by salmon lice Lepeophtheirus salmonis (Krøyer, 1837) has increasingly included biological/ecological mechanisms to combat infestation. One aspect of ... -
Effects of airgun discharges used in seismic surveys on development and mortality in nauplii of the copepod Acartia tonsa
Vereide, Emilie Hernes; Mihaljevic, Marina; Browman, Howard; Fields, David M.; Agersted, Mette Dalgaard; Titelman, Josefin; Jong, Karen de (Peer reviewed; Journal article, 2023)Seismic surveys are conducted worldwide to explore for oil and gas deposits and to map subsea formations. The airguns used in these surveys emit low-frequency sound waves. Studies on zooplankton responses to airguns report ... -

Light Primes the Escape Response of the Calanoid Copepod, Calanus finmarchicus
Fields, David M.; Shema, Steven D.; Browman, Howard I.; Browne, Thomas Q.; Skiftesvik, Anne Berit (Journal article; Peer reviewed, 2012-06-27)The timing and magnitude of an escape reaction is often the determining factor governing a copepod’s success at avoiding predation. Copepods initiate rapid and directed escapes in response to fluid signals created by ... -
A positive temperature-dependent effect of elevated CO<inf>2</inf> on growth and lipid accumulation in the planktonic copepod, Calanus finmarchicus
Fields, David M.; Runge, Jeffrey A.; Thompson, Cameron; Durif, Caroline; Shema, Steven D.; Bjelland, Reidun Marie; Niemisto, Maura; Arts, Michael T.; Skiftesvik, Anne Berit; Browman, Howard (Peer reviewed; Journal article, 2022)Calanus finmarchicus were reared from eggs to adults at 12°C and 16°C with non-limiting food in combination with ambient (600 μatm) and high (1100 μatm) pCO2. These conditions are likely to be encountered by the species ... -
