Physical Factors Affecting the Abundance and Distribution of the Pacific Sand Lance Ammodytes hexapterus in the San Juan Archipelago
Anecdotal evidence has suggested in the past that the Pacific Sand Lance, Ammodytes hexapterus is present every other year in the San Juan Archipelago. This study found the fish to be present in the San Juans, as they were last year, but not as abundant as in previous years sampling. As in numerous past studies, the A. ...
Physical influences on spatial and temporal distribution of Pacific Sand Lance (Ammodytes hexapterus) in the sand wave fields of San Juan Channel
Pacific sand lance (Ammodytes hexapterus) inhabit subtidal sediment wave fields in the San Juan Islands of Washington state. Although they are an important forage fish, serving as a trophic link between zooplankton and larger organisms, very little is known of the life history of subtidal sand lance in the sediment wave ...
Taking turns: some aspects of behavioural lateralization in schooling fish
Lateralization of cognitive functions seems to be exceptionally widespread in nature and have been demonstrated to occur in multiple taxa. Previous studies using fish as models have suggested that social behaviours such as schooling may covary with behavioural lateralization at the population-level. Here, we assess the ...
Effect of Grain Size on the Burrowing Force of Pacific Sand Lance
Pacific sand lances, Ammodytes personatus, are nutrient dense forage fish important to salmon recovery and orca conservation in the San Juan archipelago. Sand lances burrow into sandy sediments during quiescence and in response to threats. Ammodytes spp. choose habitats with specific sizes of sediment particles, but the ...
