| Some ecologists have focused on the importance of natural population regulation by biotic factors, while others have emphasized the importance of abiotic factors. |
|
| Development of models of intraspecific body size variation incorporating abiotic and biotic factors would be useful. |
|
| Numerous interacting abiotic and biotic factors have profound effects on nest sites and incubating females. |
|
| In order to live there, they must adapt to abiotic factors, such as temperature, light, and waves, and biotic factors such as predation. |
|
| In the experimental controls, the PAH loss due to abiotic or biotic factors were negligible. |
|
| However, its yield and quality is constrained by both abiotic and biotic factors. |
|
| The efficiency of bioaugmentation is determined by many abiotic and biotic factors discussed in this paper. |
|
| We find that abiotic and biotic factors interact to promote pattern formation. |
|
| Effects were also moderated by site conditions such as weather extremes and biotic factors. |
|
| The roles of limiting factors and biotic factors in the dynamics of suprabenthic assemblages are also addressed. |
|
| Tree crown defoliation is influenced by tree age, weather extremes and biotic factors. |
|
| The relevant environmental noise to be taken into account is not a single abiotic factor, but rather the combined effect of all abiotic and biotic factors that affect birth and death rates. |
|
| Their turnover is usually determined by species, age groups, canopy cover, weather conditions and biotic factors. |
|
| In addition to the physical or abiotic factors affecting life on the shore, ecologists have identified a number of biological or biotic factors to which many organisms also have to adapt. |
|
| Canada comprises 15 terrestrial ecozones, areas of the earth's surface representative of large and very generalized units characterized by interactive and adjusting abiotic and biotic factors. |
|
| Plant indicators: the existing vegetation, being itself the result of the interacting factors of climate, soil, topography, historical and biotic factors, may give valuable indications as to the characteristics of the site. |
|
| Environment, the complex of physical, chemical, and biotic factors that act upon an organism or an ecological community and ultimately determine its form and survival. |
|
| For the ecological integrity mandate of Parks Canada, environmental quality decreases as undesirable physical, chemical and biotic factors increase in the environment. |
