| alternate cover test | A test to detect phoria or strabismus; attention is directed to a small fixation object, and one eye is covered for several seconds; then the cover is moved quickly to the other eye; if the eye moves when it is uncovered, a strabismus or phoria is present. (05 Mar 2000) |

| alternate | Cause to occur or appear one after the other. (18 Nov 1997) |
| alternate binaural loudness balance test | ABLB test, a test for recruitment in one ear; the comparison of relative loudness of a series of intensities presented alternately to either ear. (05 Mar 2000) |
| alternate day strabismus | Periodic convergent strabismus often occurring every 48 hours. Synonym: alternate day strabismus. (05 Mar 2000) |
| binaural alternate loudness balance test | A test for recruitment in one ear; the comparison of relative loudness of a series of intensities presented alternately to either ear. Synonym: BALB test. (05 Mar 2000) |
| areal cover | <botany, ecology> A measure of dominance that defines the degree to which above ground portions of plants cover the ground surface, it is possible for the total areal cover for all strata combined in a community or for single stratum to exceed 100 percent because: most plant communities consist of two or more vegetative strata. Areal cover is estimated by vegetative layer, and foliage within a single layer may overlap. (09 Oct 1997) |
| vegetative fish cover | <ecology> Vegetation materials, such as algal mats and organic debris, capable of providing protection for fish and other aquatic organisms. (06 Mar 2000) |
| cover | Anything that provides protection from predators or ameliorates adverse conditions of streamflow and/or seasonal changes in metabolic costs. May be instream cover, turbulence, and/or overhead cover, and may be for the purpose of escape, feeding, hiding, or resting. (09 Oct 1997) |
| cover class | A category into which plant species would fit based upon their percent areal cover, the cover classes used (midpoints in parentheses) are T = <1% cover (0), 1 = 1-5% (3.0), 2 = 6-15% (10.5), 7 = 51-75% (63.0), 6 = 76-95% (85.5), 7 = 96-100% (98.0). (09 Oct 1997) |
| cover glass | A thin glass disk or plate covering an object examined under the microscope. Synonym: coverslip. (05 Mar 2000) |
| cover test | A test used for objective demonstration of ocular deviation in strabismus; may be performed by two methods: the cover-uncover test and the alternate cover test. (05 Mar 2000) |
| cover-uncover test | A test to detect strabismus; the patient's attention is directed to a small fixation object, one eye is covered and after a few seconds, uncovered; if the uncovered eye moves to see the picture, strabismus is present. (05 Mar 2000) |
| prism cover test | Measurement of the deviation in strabismus by the alternate cover test combined with neutralization for the deviation using prisms. (05 Mar 2000) |
| shaded riverine aquatic cover | Near-shore aquatic area occurring at the interface between a stream and adjacent woody habitat. (09 Oct 1997) |
| instream cover | Areas of shelter in a stream channel that provide aquatic organisms protection from predators or competitors and/or a place in which to rest and conserve energy due to a reduction in the force of the current. (09 Oct 1997) |
