Ecologists sample areas in the environment they wish to study to work out a vague idea of the numbers of different species in their habitat. 4 methods of sampling are used; Quadrats, Random sampling, Systematic sampling using transects and the Lincoln index (mark-release-recapture). For mobile animals the best method is the Lincoln index which is an estimation of population size using to samples of the area. First they sample the area capturing the species they desire and mark them with a non toxic marker. After a suitable period of time they re sample the area. Estimated population size = Number of individuals caught in 1st sample * Number of individuals caught in 2nd sample/total number of individuals re caught from 1st sample in the 2nd sample. Assumptions must be made for the whole sample and statistical tests must be used to detect any factor that would have an effect on the results e.g. chance.

Sampling - counting the number of organisms in a small area and multiplying to estimate the number in a larger areaMark & Recapture - capture an organism & release it to remix with population. Then recapture some more in that area to determine population size. Formula is as follows: R (marked recaptures) / C (total in second sample) = M (marked initially) / N (total pop. size)Indirect Observation - estimating the population size by tracks, nest or other animal signs in an ecosystem.Direct Observation - count all members of a population in an ecosystem

It depends on where the larva was obtained. If the larva is from the Eastern Population (Blue Mountain region) it feeds on Hernandia catalpifolia. If the larva is from the Cockpit Country it feeds on Hernandia jamaicensis. I suggest that if you are in possession of a homerus swallowtail larva that you either release it where you found it (in Jamaica), or contact Matt Lehnert (University of Florida). This is an endangered species and it is illegal to have one in captivity without proper authorization and it is important to keep individuals in the wild to reproduce with other wild individuals.
No, pure water does not conduct electricity. However, adding an electrolyte, preferably a salt, will release ions into the solution that make it electrically conductive.

Heat promoting mechanism include exothermic reactions and the radiating of heat through conductance. Exothermic reactions include the combustion of carbon based fuels which release heat. The radiating of heat can come from electronic space heater that release warmth through their conducting metal filaments.
Some do, many in fact. Violate the terms of your work release and you will likely find yourself in a cell in the general population.
He sacrificed himself for humanity. To release Juno....to save the global population.
Socialization helps one to release stress and other mental problems. it also helps in good character formation in the individuals
The US Census Bureau did not release year to year population estimates until after the 1900 Census. The 1890 Census was mostly destroyed in a fire, but the population calculated was 62,947,714. The 1900 Census calculated 76,212,168 Americans. So the population in 1892 was most likely between 65 and 66 million.
About 28% of the population has at least a Bachelor's degree. http://www.census.gov/Press-Release/www/releases/archives/education/004214.html
