Aging: a natural history

Introducing Books/ Dagestan: A Natural History, Mehrnaz Shirazi Adl

The natural history of telomeres: tools for aging animals and exploring the aging process.

We have been exploring the use of telomere length as a technique to age animals. If telomere restriction fragments (TRFs) shorten predictably with age in a particular tissue, then measurement of TRFs will allow estimation of ages of animals when age cannot be measured directly. This would be particularly useful in population studies where tissue samples can be collected, but age of individuals ...

Natural history , life history , and

We report on basic natural history, life history, and diet of Priapella chamulae (Poeciliidae) from Arroyo Tres, a small creek in Tabasco, southern México. The tertiary (adult) sex ratio was heavily female-skewed, female P. chamulae produced medium-sized offspring (~2.3 mg), one clutch at a time (i.e., showed no superfetation), and relied predominantly on yolk for embryo provisioning (Matrotrop...

A Natural History of Peace

More discomfiting is the continuum that has been demonstrated in the realm of cognition. We now know, for example, that other species invent tools and use them with dexterity and local cultural variation. Other primates display "semanticity" (the use of symbols to refer to objects and actions) in their communication in ways that would impress any linguist. And experiments have shown other prima...

A natural history of vision

strictly European. This classification has certainly given her difficulties in writing her narrative histories but it lends itself readily enough to a bibliography. Perhaps the structure leaves too little to chance. It is odd to find Buffon and Walter Charleton bracketed in the same time span ('Biologists in the seventeenth and eighteenth centuries') and counter-intuitive to search for Blumenba...
