The reasons for this are unclear; the characteristics captured in our models may be useful in defining the minimum ecologic conditions necessary for transmission, but other influences such as the demographics, behavior, and herd immunity of human and reservoir populations may exert a stronger influence on incidence rates within these ecologically suitable areas.
…California Indian land management practices are ecologically sound and even necessary for maintaining the delicate ecosystems across the state" (LeBeau 1998).
At first glance, the researchers say, the persistence of beetles can likely be ascribed to their wide range of dietary habits, their ability to move to find ecologically suitable habitat when necessary, and their adaptability in case environmental conditions have dramatically changed.
Our results support the designation of baboons as highly flexible "generalists," and suggest that more fine-grained analyses (e.g., relative success in ecologically stressful years) may be necessary to detect clear signals of ecological barriers to gene flow.
In March and April 1995 the cabinet agreed to accelerate the process and fund more agreements, arguing that it was necessary to achieve "ecologically sustainable resource use and management which fulfils both commonwealth and state objectives for a forest region".
It is therefore necessary to exclude ecologically sensible areas from potential HVDC corridors.
For genetic evolution to occur, genetic diversity for ecologically relevant traits is a necessary precondition.
Because dragonfly larvae were frequently found in our study populations, the presence of predator cues was necessary to obtain ecologically realistic phenotypes of newt larvae for predation experiments.
First, whenever ecologically sensitive areas ("ecological sites") are used for agricultural production, it is necessary to take account of the fact that farmers tend to adapt to environmental requirements by production responses outside the ecological site itself.
Quintuple Helix stresses the necessary socio-ecological transition of society and economy in the 21st century; therefore, the Quintuple Helix is ecologically sensitive.
