Periphyton cultivation systems have few controls over species composition, thereby limiting their applications for production of biomass.
In order to improve the control over both species independently, we employ this fact constructing a species-selective conveyor-belt lattice allowing for trapping and controlled transport of impurity atoms, only.
When charcoal comes to be used as cooking fuel in a given country, the speedy introduction of procedures encouraging the use of light charcoal (sale by weight, quality-based prices, control over the species used, etc). could limit overexploitation and encourage production from plantation species, to the considerable benefit of the environment and consumers.
Our team had absolutely no control over the species selected by hunters, and also worked closely in the field with staff from the Cameroonian ministry responsible for wildlife to ensure that it was clear to hunters which species were protected and should not be hunted.
After having prepared a statement as to the uses of poplar wood and put the finishing touches to a record of identification, the Commission studied a plan of nomenclature for poplars as well as other questions of great interest, particularly those of the exchange between countries of species of poplars, the fight against crust (canker), and the institution of control over the various species.
For a small extra charge we can go up to 160!' I don't know if we're cut out to have that kind of control over our own species". The way in which Reich looks forward and engages with the reality of the modern age could mask the fact that he comes from a classical background.
In theory, that gives our species control over biological design.
Key to the widespread application of these materials are the various synthetic schemes that have been developed to provide control over the types of species incorporated and, more importantly, their distributions within the mesostructured hosts.
If the changes go ahead, two key pieces of NSW's environmental legislation its Threatened Species Conservation Act and the Native Vegetation Act will be repealed and replaced with new laws aiming to give farmers more control over conservation of native species on private land.
One of the central premises of biogeography is that climate exerts a dominant control over the distribution of species [ 63, 64].
It is not clear why females of some species are able to retain some control over their reproduction whereas other species seem to be at the mercy of manipulative males.
