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 ...
Mitochondrial genomes of Clymenella torquata (Maldanidae) and Riftia pachyptila (Siboglinidae) : evidence for conserved gene order in Annelida
Mitochondrial genomes are useful tools for inferring evolutionary history. However, many taxa are poorly represented by available data. Thus, to further understand the phylogenetic potential of complete mitochondrial ...
Diversity in sound pressure levels and estimated active space of resident killer whale vocalizations
Signal source intensity and detection range, which integrates source intensity with propagation loss, background noise and receiver hearing abilities, are important characteristics of communication signals. Apparent source ...
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 ...
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.
A new family of giardial cysteine-rich non-VSP protein genes and a novel cyst protein
(Public Library of Science, 2006-12)
Since the Giardia lamblia cyst wall is necessary for survival in the environment and host infection, we tested the hypothesis that it contains proteins other than the three known cyst wall proteins. Serial analysis of gene ...
Effects of nutrients, salinity, pH and light:dark cycle on the production of reactive oxygen species in the alga Chattonella marina
Experiments were carried out to investigate the effects of nutrients, salinity, pH and light:dark cycle on growth rate and production of reactive oxygen species (ROS) by Chattonella marina, a harmful algal bloom (HAB) ...
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.
