Based on the concept of adjoint equation for a given differential equation [9], Ibragimov gives a general conservation theorem by which conservation laws for the system consisting of the given equation and its adjoint equation can be obtained.
However, this lack of sequence similarity did not result in a lack of conservation by position, which could indicate a conservation of function as it has been shown earlier that positional conservation also accounts for functional conservation [ 15, 30].
Recent conservation approaches have focused on the landscape as either a conservation target or a mechanism by which conservation can be achieved.
However, strong systems of traditional resource ownership and customary law provide an alternative route by which conservation plans can be developed and implemented by communities with customary tenure, e.g.. Here, conservation planning might better be institutionalised within customary, rather than formal, governance structures.
Following the resolution by the Convention on Biological Diversity to almost double the extent of the world's protected areas by 2020 (Normile, 2010; UNEP/CBD, 2010), there will be widespread demand for methods and operational models by which conservation resources can be allocated spatially in an effective manner.
If the economic potential of kauri can be unlocked then growing kauri in plantations in-situ and ex-situ is a potential means by which both conservation and production outcomes might be achieved.
Their tactics have also included the purchase of "conservation easements" - a method by which local communities in Colorado can pay landowners or leaseholders not to develop certain areas.
The entropy of an alignment site is a measure of variation in its state and a criterion by which sequence conservation can be objectively quantified: entropy is zero at invariant sites and has a maximum value of one when all possible states (residues) occur equally frequently (or proportional to the background composition).
Given the conservation of kleisins, the mechanism by which DNA passes two sequential gates to enter or exit is likely conserved among SMC complexes.
This is not completely unexpected, because substantial sequence conservation is often a criterion by which researchers choose targets for further study.
