Abstract Many biological features of Chattonella species display diurnal oscillations, but little is known about the corresponding cellular responses at the proteome level. In the present study, we hypothesized that the abundance of certain proteins would periodically fluctuate to suit the diurnal changes of biological processes in Chattonella cells. To test this hypothesis, we undertook proteomic analysis over 7 time points covering a 24-h period in C. marina var. antiqua cells at early station...

Abstract We investigated aminoacyl-tRNA synthetases (AARS) activity and individual growth rate (IGR) as individual-based in situ indicators of growth in adult krill, Euphausia pacifica. AARS enzymes catalyze the first step in protein synthesis while the IGR method is based on changes in body length during molting. Growth rates of field-collected krill were measured via the IGR method and individuals were subsequently preserved for AARS analysis to yield paired measurements. Our results show that...
Abstract Salinity is a key variable influencing the life history of aquatic organisms. Environmental variability in salinity has been associated with increases in the formation of reactive species, ending up in a state of oxidative stress. In copepods, information about effects of salinity variations mostly includes data from short-term experiments where the effects of salinity changes are evaluated in terms of survival and vital rates, and data involving oxidative stress biomarkers are limited....

Abstract The dispersal of fish larvae during the early life stages plays an important role in recruitment. Together with oceanographic processes, larval orientation and swimming behavior significantly influences dispersal. However, currently there is no information of larval behavior in situ for most subpolar species. The Atlantic herring (Clupea harengus) is an ecologically and commercially important component of the North Atlantic ecosystem. This species has sustained a large fishery for over ...
Abstract Shorthorn sculpin (Myoxocephalus scorpius) and large cod (300–400 g body weight) are important predators on newly settled 0-group cod (Gadus morhua) and saithe (Pollachius virens) in Porsangerfjorden in northern Norway. The Atlantic wolffish (Anarhichas lupus) used to be abundant but is now very rare in the fjord. Video recorded experiments showed that interactions between shorthorn sculpins, wolffish and large cod affected predation rates on small 0-group cod and saithe in tanks with a...

Abstract In this study we investigated the metabolic consequences of simulated gillnet capture in species with contrasting life-history characteristics, the gummy shark, Mustelus antarcticus and the Port Jackson shark, Heterdontus portusjacksoni. Pre-stress standard and routine metabolic rates (MR) of individuals of these species were measured and compared to the MR obtained after simulated gillnet capture. Standard MRs of M. antarcticus and H. portusjacksoni were 168.5 ± 61.9 mgO2 kg-0.67 h−1 a...
Abstract Measuring protein is critical to many investigations in oceanography and marine biology. Here, we compared seven colorimetric protein assays (Rutter, Rutter-SDS, Markwell, BCA, microBCA, Bradford and microBradford) for measuring protein in a mysid (Leptomysis lingvura), in a jellyfish (Pelagia noctiluca), and in three different size fractions of marine plankton (0.7–50, 50–200 and 200-2000 μm). Significant differences occurred in all of these samples. However, the mBCA method was the mo...
Abstract Structural complexity plays an important role in mediating predator-prey interactions. Structural elements can limit predator mobility and ability to detect prey, increasing prey survival. Seagrasses are marine plants that provide refuge for many fishes and invertebrates by increasing the structural complexity of the benthos. Though prey survival often is positively correlated with seagrass biomass or shoot density, seagrasses frequently are colonized by epibiotic organisms such as alga...

Abstract Totoaba macdonaldi, an endemic fish from the Gulf of California, is currently considered an endangered species by the Mexican Federal Government since its bladder is a high-priced item in China's black market. Totoaba is considered the cause of extinction of the marine porpoise vaquita marina (Phocoena sinus) due to Illegal fishing. It inhabits the Colorado Delta River Marine Reserve, an area with very high productivity, biomass, species endemism, and a marine nursery. To explore its os...

Abstract Aerial survey methods for census of wildlife populations are widely used to manage species. There has been considerable research to develop methods to cope with imperfect detection during aerial surveys, however misidentification remains an unresolved but significant issue. Using data from a comprehensive dugong aerial survey of the coastline of the Northern Territory, Australia, we assessed the influence of observer, sighting and environmental variables on probabilities of both observe...
