Life-time records of the trophic sources of carbon, nitrogen and of growth rate can be generated from biogenic structures that show accretionary growth, including fish scales, whale baleen and the teeth of some animals. Records generated from individual teeth can also be combined to provide longer time series elucidating changes in environmental conditions encountered by a population. Both intr...
In this study, minimum audible angles (MAAs) of aerial pure tones were measured in and compared between a northern elephant seal (Mirounga angustirostris), a harbor seal (Phoca vitulina), and a California sea lion (Zalophus californianus). Testing was conducted between 0.8 and 16 kHz in the elephant seal and 0.8 and 20 kHz in the harbor seal and sea lion in a hemi-anechoic chamber using a left/...
The indirect peroxidase method was employed to study the endocrine pancreas of the Cape fur seal. Immunoreactivity to insulin was confined to the cores of the islets and the insulin cells were more abundant than the other endocrine cell types, which occurred mainly in the mantles of the islets. Of these, glucagon cells were the most numerous, followed by somatostatin and pancreatic polypeptide ...
Hinwood, J.B. and McLean, E.J., 2000. Monitoring and modelling tidal regime changes following inlet scour. Journal of Coastal Research. Royal Palm Beach (Florida), ISSN J. Coastal Research, Special Publn. 34, pp 449-458, 2001 Entrance closure has been identified by the local coastal communities as one of the more important management problems for the small barrier estuaries. The paper describes...
AMBI is an ecological marine ecosystem indicator, which provides a more intelligent assessment of ecosystems of sensitivity and resilience, and ecological role, compared to famous diversity and dominance. This study assesses ecosystem health status from the AMBI's perspective by examining the distribution and biodiversity of macrobenthoses from mangrove of Mel-e-Gonzeh in the Bushehr province. ...
Chabahar Bay is a semi-closed and shallow bay in southeastern of Iran and is strongly affected by the monsoon conditions. The 3D FVCOM model was used to study the hydrodynamic conditions of Chabahar Bay. For this purpose, a horizontal grid with 6290 triangular elements and a vertical grid with 10 sigma layers were created. The model was implemented in baroclinic mode; NCEP data and HYCOM model ...
