The basic structure of the habitats, for instance, is designed around a hollow tube made of metal and glass.
As the HPC 2,3-dioxygenase (HpaD) requires molecular oxygen, utilization of the HPC meta-cleavage pathway is restricted to distinct intestinal habitats, for instance ones in close proximity to epithelial cells, where oxygen molecules might pass from the blood to the microbes attached to the epithelium [ 40].
"They maintain enhancement of suitable habitat – for instance, hares like fields with rushes where they can hide.
This term can be interpreted as a total or partial 'culling' action on the infection in the sense that all of a part of the infected individuals are removed from the habitat by using, for instance, quarantine or simply removal.
The use of only one host, however, may limit the exploitation of microbial diversity for a given habitat due to, for instance, differences in codon utilization and/or mRNA and protein stability among different hosts.
In the light of this, and following the proposal of distinguishing between competing models of diversification for North and Mesoamerica [ 43], we can emphasise tecto-volcanic processes as the crucial factors influencing the evolutionary history of C. ornatum, rather than recent habitat fluctuations caused, for instance, by alternating glacial/interglacial stages.
When laboratory work has proved futile, they have gone into the field, observing people in their natural habitats — a college campus, for instance, where, one researcher told me, he set out to watch students "as if they were primates in the wild".
For instance, fragmented habitats may support less pollinators than continuous habitats due to limited resource availability for pollinators (area-related effects on animal populations).
Poor management decisions may increase land degradation through, for instance, habitat fragmentation, soil erosion, decreases in biodiversity, the introduction of invasive species, and loss of watershed capacity (Richards 1990; Bennett and Saunders 2010).
A major threat to ecological communities and their diversity is rapid environmental change as caused by, for instance, habitat degradation, species invasions, or shifts in marine current regimes [29], [30].
For instance, habitat alteration might be so drastic that the variation required to adapt is simply not available.
