| This pattern may suggest some form of morphological stability due to selection, canalization, or a constraint operating on wing shape. |
|
| Physiological canalization may limit the number of phenotypes that can be produced in response to environmental variation. |
|
| Pressure for land has led to the canalization of rivers and an increased water flow. |
|
| This last mechanism is known as canalization and can lead to the buildup of hidden or cryptic genetic variation. |
|
| It is fitted with a pipe to make the water flowing and a second one to blow out the the ais inside the canalization. |
|
| The sea water travels about 200 km from its first canalization to the basins where precipitation of the salt occurs. |
|
| Also, canalization, with its extensive system of locks and navigation dams, often seriously disrupts riverine ecosystems. |
|
| Do not leave undiluted or in large quantities in ground water, watercourses or canalization. |
|
| The system of canalization drains the rain water into a storage tank at the bottom of each structure. |
|
| Extensive canalization and a vast development of polders have been systematically carried out since the early 20th century. |
|
| The town doesn't have underground network of canalization and doesn't have enough water. |
|
| Air duct heaters are used for the heating of air or process air through canalization. |
|
| These morphological facts show that the pentadactyl limb arose after the fin-limb transition and is the product of the canalization of the phenotype of the archaic limbs. |
|
| The decline in iPod sales is partially attributed to canalization by the iPod touch. |
|
| The problem is particularly acute with regard to canalization of free flowing rivers, as well as some maintenance works, such as dredging and disposal of dredged material. |
|
| Persistence of a membrane at the lower end of the nasolacrimal duct results in incomplete canalization of the duct and its consequent obstruction. |
|
| There appears to be considerable levels of organized poaching of wildlife, illegal felling of trees, encroachment and canalization of facilities within the site. |
|
| Freshwater ecosystems are threatened by dam construction, dredging and canalization, lack of sanitation and sewage, drainage of wetlands and deforestation. |
|
| These are threatened by rival canalization and drainage schemes such as the Bystroye Canal. |
|
| Purchase of water, canalization materials and spare parts for the PCE Derven Veles needs. |
|
|
|
| Many townships have been built in Kabul City without considering recreational facilities, proper canalization and drainage, he added. |
|
| Along the way is a system of water canalization, sometimes underground, which parallels the path from the noria of the Batán river to the Rivera power station, and which is embedded in the retaining walls embanking the river. |
|
| The canalization of the tributaries of the Loire river, under the impetus of Dutch trade, contributed greatly to the development of the vineyard during the 16th and 17th centuries. |
|
| At the end of 30 minutes of rainfall water overflew from the canalization. |
