The Poverty of mathematical and existential truth: examples from fisheries science
(2011-06-27)
Several years ago I suggested that the harvesting of our commercial fisheries could be improved if the non-falsifiable models of a fisheries science were to be replaced with the falsiable models of a fisheries economics. ...
Observations on a mixed farm during the transition to biological husbandry
(2011-01-19)
Tunwath is a mixed farm (laying hens-grains) located in the Annapolis Valley, Nova Scotia, in a cool humid temperate zone. It includes about 2100 laying hens, 35 hectares of field crops and additional garden, pasture, hay ...
Historical changes in genotypic frequencies at the Pantophysin locus in Atlantic cod (Gadus morhua) in Icelandic waters: evidence of fisheries-induced selection?
(2011-07)
The intense fishing mortality imposed on Atlantic cod in Icelandic waters during recent decades has resulted in marked changes in stock abundance, as well as in age and size composition. Using a molecular marker known to ...
Food-Web Structure of Seagrass Communities across Different Spatial Scales and Human Impacts
(2011-07)
Seagrass beds provide important habitat for a wide range of marine species but are threatened by multiple human impacts in coastal waters. Although seagrass communities have been well-studied in the field, a quantification ...
The Influence of Reproductive Experience on Milk Energy Output and Lactation Performance in the Grey Seal (Halichoerus grypus)
(2011-05)
Although evidence from domestic and laboratory species suggests that reproductive experience
plays a critical role in the development of aspects of lactation performance, whether reproductive
experience may have a significant ...
Rapid Global Expansion of Invertebrate Fisheries: Trends, Drivers, and Ecosystem Effects
(2011-03)
Background: Worldwide, finfish fisheries are receiving increasing assessment and regulation, slowly leading to more sustainable exploitation and rebuilding. In their wake, invertebrate fisheries are rapidly expanding with ...
Computer-Assisted Photo-Identification of Narwhals
(2011-09)
Although the narwhal (Monodon monoceros) is economically and culturally important to northern residents, sound management of this species is impaired by large gaps in knowledge. Research on this species has been limited ...
Hybridization effects on phenotypic plasticity: experimental compensatory growth in farmed-wild Atlantic salmon
(2011-05)
Compensatory growth (CG) is a means by which organisms can increase their growth rate above
their routine growth rate after a period of environmentally induced growth depression. Despite a
focus on the implications of ...
Assessing the Value of Recreational Divers for Censusing Elasmobranchs
(2011-10)
Background: Around the world, researchers are using the observations and experiences of citizens to describe patterns in animal populations. This data is often collected via ongoing sampling or by synthesizing past ...
