An analysis of fishing vessel accidents in fishing areas off the northeastern United States
Commercial fishing is one of the least safe occupations. Fishing vessel accident probability and vessel trip probability for fishing areas off the northeastern United States were modeled using logit regression and daily ...
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.
Oceanography : plankton in a warmer world
Satellite data show that phytoplankton biomass and growth generally decline as the oceans’ surface waters warm up. Is this trend, seen over the past decade, a harbinger of the future for marine ecosystems?
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.
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 ...
Aqueous phase methylation as a potential source of methylmercury in wet deposition
The source of monomethylmercury (MMHg) in wet deposition is unknown. Volatilization of gaseous MMHg, evasion and demethylation of dimethylmercury, and methylation of Hg0 have been either proposed or tested unsuccessfully ...
A recipe for simulating the interannual variability of the Asian summer monsoon and its relation with ENSO
This study investigates how accurately the interannual variability over the Indian Ocean basin and the relationship between the Indian summer monsoon and the El Nino Southern Oscillation (ENSO) can be simulated by different ...
Geochemical proxies of North American freshwater routing during the Younger Dryas cold event
The Younger Dryas cold interval represents a time when much of the Northern Hemisphere cooled from ~12.9 to 11.5 kiloyears before present. The cause of this event, which has long been viewed as the canonical example of ...
