Description

My last publications are a radical departure from my previous efforts’

Instead of focusing on we saw rigs, we walked here and we ate this, my content is now centered on the history and science verse, including the anthropology, archeology,  culture, ecosystems, geology, natural history and wildlife biology.



I hope that you will enjoy my improved content.

Back when a mere lad of 15 and taking 10th grade Biology, Ecosystems were never even mentioned. My teacher, Mrs. Anne Elam, concentrated all her efforts upon Parthenogenesis, Frog Anatomy and the Health Hazards of Smoking.


Not until the publication of Rachel Carson’s Silent Spring did it, the Environment, Biodiversity, Life Distribution, Biomass, and PopulationGenetics become all the rage and rightfully so.


Biodiversity itself is not evenly distributed, rather it varies greatly across the globe as well as within regions. Among other factors, the diversity of all living things (biota) depends on temperature, precipitation, altitude, soils, geography and the presence of other species. The study of the spatial distribution of organisms, species and ecosystems, is the science of biogeography.


Diversity consistently measures higher in the tropics and lower in polar regions generally. Rainforests that have had wet climates for a long time, such as Yasuní National Park in Ecuador, are particularly high in Biodiversity.


Terrestrial Biodiversity is thought to be up to 25 times greater than Ocean Biodiversity. A new method, first  used in 2011, put the total number of species on Earth at 8.7 million, of which 2.1 million were estimated to live in the ocean.


However, this estimate seems to under-represent the total diversity of microorganisms, particularly viruses.
