The positive tRFP signal was maintained in all palpable +Dox tumors throughout the life span of the mice, assuring the persistence of shPTEN expression in this xenograft mouse model.
Hypothetical management scenarios were used to identify critical data needed to assure the persistence of reintroduced populations of American martens (Martes americana).
The remoteness and isolation character of these mountains might have assured the persistence of crocodiles.
A strain with a low resistance level does not have enough selective advantage to assure its persistence in the population.
If climatic alterations take place as predicted, static protected areas may not assure habitat persistence and ecosystem functioning and may not, in the long run, support all the species they were designed to protect [ 3, 5, 11].
This is partly because hermaphroditism and selfing occur in multiple forms, not all of which clearly assure population persistence in environments with limited opportunity for outcrossing [ 17, 25- 28].
The persistence assured by aggregates allows evolution and adaptation of interacting microbial communities despite environmental disruptions.
Assured growth, persistence and accessibility of databases are therefore imperative to encourage and support data deposition.
Despite challenges, applying past lessons in large landscape conservation while addressing human needs, along with concerted global action, could assure the long-term persistence of wild cheetahs.
For the purposes of conserving rare species that are threatened by outbreaks of infectious disease, population persistence may be assured by a vaccination strategy designed to suppress only the largest outbreaks of disease that reduce the population to below a minimum viable population size.
