Detailed genetic diversity studies on the naturally occurring variation of African Oryza are however limited, thus constituting a major information gap that greatly hampers establishment of these reserves.
Can transparency hamper governance?
Nutrient dynamics within the constructed fen suggest that phosphorus limitation (N P ratio > 20) could hamper the establishment of a diverse plant community, whereas the build-up of microbial biomass appears to be NO3− limited.
New demographic conditions, such as Allee effects or genetic drift in small populations, can hamper successful establishment (Sakai et al. 2001).
Research on what cultural traits within the professions may facilitate or hamper the establishment of teams characterized by trust and collaboration is scarce.
These factors were felt to hamper the establishment and progress of network projects and was an ongoing source of frustration: "They'll participate but they'll do it at their speed when it's convenient for them and how they want to do it.
The dynamic developmental theory of ADHD states that a combination of a short delay-of-reinforcement gradient, which will hamper the establishment of long integrated behavioral chains, and a deficient extinction process will result in increased behavioral variability [ 13, 20, 25, 26].
A notable point is that mutations in genes required for any one particular molecular process, such as chloroplast RNA processing, severely hamper the establishment of photosynthetic competence in general, as many mutants are pale green, albino or even embryo lethal (Table I).
The difficulty in controlling the broad number of factors affecting interactions between GBMs and bacteria hampers the establishment of clear cause-effect relations.
In summary, the scarcity of comparative available data hampered the establishment of any firm conclusions regarding the benefit that various treatment strategies may confer to patients with 2009 H1N1 influenza.
