Light Primes the Escape Response of the Calanoid Copepod, Calanus finmarchicus
(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 ...
Ocean biodiversity informatics (OBI): Introduction
(Journal article; Peer reviewed, 2006-07-03)
Moral, ethical and scientific aspects of welfare in aquatic organisms
(Journal article; Peer reviewed, 2007-05-04)
Grazing Rates of Calanus finmarchicus on Thalassiosira weissflogii Cultured under Different Levels of Ultraviolet Radiation
(Journal article; Peer reviewed, 2011-10-18)
UVB alters photosynthetic rate, fatty acid profiles and morphological characteristics of phytoplankton. Copepods, important grazers of primary production, select algal cells based upon their size, morphological traits, ...
Effect of Sub-Lethal Exposure to Ultraviolet Radiation on the Escape Performance of Atlantic Cod Larvae (Gadus morhua)
(Journal article; Peer reviewed, 2012-04-19)
The amount of ultraviolet (UV) radiation reaching the earth’s surface has increased due to depletion of the ozone layer. Several studies have reported that UV radiation reduces survival of fish larvae. However, indirect ...
Magnetic Compass Orientation in the European Eel
(Journal article; Peer reviewed, 2013-03-15)
European eel migrate from freshwater or coastal habitats throughout Europe to their spawning grounds in the Sargasso Sea. However, their route (~ 6000 km) and orientation mechanisms are unknown. Several attempts have been ...
Foraging behaviour of larval cod (Gadus morhua) at low light intensities
(Journal article; Peer reviewed, 2011-02-13)
The ability to forage at low light intensities can be of great importance for the survival of fish larvae in a pelagic environment. Three-dimensional silhouette imaging was used to observe larval cod foraging and swimming ...
The three-dimensional prey field of the northern krill, Meganyctiphanes norvegica, and the escape responses of their copepod prey
(Journal article; Peer reviewed, 2010-02-24)
In the north Atlantic, Meganyctiphanes norvegica feeds predominantly on copepods, including Calanus spp. To quantify its perceptual field for prey, and the sensory systems underlying prey detection, the responses of tethered ...
Bridging the gap between aquatic and terrestrial ecology
(Journal article; Peer reviewed, 2005-12-08)
Welfare of aquatic organisms: Is there some faith-based HARKing going on here?
(Journal article; Peer reviewed, 2011-05-09)
Much of the literature on aquatic animal welfare is flawed by 4 non-mutually exclusive (and often inter-related) biases: under-reporting/ignoring of negative results, faith-based research and/or interpretations, Hypothesizing ...
