Summer and fall habitat of North Atlantic right whales (Eubalaena glacialis) inferred from satellite telemetry
(National Research Council Canada, 2005-04-12)
Satellite-monitored radio tags were attached to North Atlantic right whales (Eubalaena glacialis) in Grand Manan Basin of the lower Bay of Fundy during the summer and early fall seasons of 1989–1991 and 2000. Monte Carlo ...
Behaviour of the ocean DMS(P) pools in the Sargasso Sea viewed in a coupled physical-biogeochemical ocean model
(National Research Council Canada, 2004-06-23)
The dimethylsulfide (DMS) production model NODEM (Northern Oceans DMS Emission Model) was coupled with the water column ocean model GOTM (General Ocean Turbulence Model) that includes a two-equation k&150;ε turbulence ...
Temperature and salinity effects on strontium incorporation in otoliths of larval spot (Leiostomus xanthurus)
(National Research Council Canada, 2004-02-03)
Temperature dependence of strontium/calcium (Sr/Ca) ratios in foraminiferal calcite and coral aragonite is well established; however, factors controlling Sr/Ca ratios in fish otoliths remain obscure. To assess temperature ...
Systemic effects of Arctic pollutants in beluga whales indicated by CYP1A1 expression
(National Institute of Environmental Health Sciences, 2005-07-14)
Cytochrome P450 1A1 (CYP1A1) is induced by exposure to polycyclic aromatic hydrocarbons (PAHs) and planar halogenated aromatic hydrocarbons (PHAHs) such as non-ortho polychlorinated biphenyls (PCBs). In this study, we ...
Essays in philosophical biology
Philosophical biology, one might venture to assert, is an effort to delve as deeply as possible into the underpinnings of biological structure. Consequently the effort will be, first, to understand how continuity can be ...
The biology and philosophy of adaptation
A logico-linguistic analysis is presented first, in which the symbolization of being adapted, having an adaptation, and having adaptedness is explained. Next the linguistic-realistic divide is portrayed. This is explained ...
The application of set theory to ecology
Sets and membership are part of the structure of the world. Sets and membership hold nature together.
Natural selection, microevolution and macroevolution
The use of logical validity and empirical data will show that natural selection occurs at the micro-evolutionary level but does not occur at the macro-evolutionary level.
Environmental health and the coastal zone
(National Institute of Environmental Health Sciences, 2002-11)
Reconciling coastal development and the maintenance of a quality environment represent an enormous management challenge to both public and private interests. Wise management of coastal areas will require an understanding ...
Biological control of the vernal population increase of Calanus finmarchicus on Georges Bank
An adjoint data assimilation approach was used to quantify the physical and biological controls on Calanus finmarchicus N3 to C stages on Georges Bank and its nearby environs. The mean seasonal cycle of vertically-averaged ...
