(n.) The science which treats of the laws of distribution of living organisms over the earth's surface as to latitude, altitude, locality, etc.
Example Sentences:
(1) The chorology of this species does not permit an explanation of the division of most of the chromosomal types which seem to be closely linked with the ecological components of the biotopes.
(2) A review of faunistic data, chorology, seasonal incidence and food preference is given and possible importance of the main species, mostly of the genus Megaselia, as potential vectors and causative agents of myiasis, is discussed.
(3) After studying more than 1,000 siphonaptera tera collected from about 300 wild carnivora (with a majority of foxes, Vulpes vulpes), in the North-east of France, the authors state more precisely the biology and chorology of the main fleas collected: Pulex irritans, Ctenocephalides felis felis, C, canis, Chaetopsylla globiceps, Ch.
Spatial
Definition:
(a.) Of or pertaining to space.
Example Sentences:
(1) The spatial spread or blur parameter of the blobs was adopted as a scale parameter.

(3) Their receptive fields comprise a temporally and spatially linear mechanism (center plus antagonistic surround) that responds to relatively low spatial frequency stimuli, and a temporally nonlinear mechanism, coextensive with the linear mechanism, that--though broad in extent--responds best to high spatial-frequency stimuli.
(4) Mice with mutations in four nonreceptor tyrosine kinase genes, fyn, src, yes, and abl, were used to study the role of these kinases in long-term potentiation (LTP) and in the relation of LTP to spatial learning and memory.
(5) It is found that, whereas the spatial resolution achievable with such a system is only dependent upon its temporal resolution, the scattering characteristics of the tissue being imaged will strongly affect the ultimate imaging performance of such a system.
(6) Two mechanisms are evident in chicks' spatial representations: a metric frame for encoding the spatial arrangement of surfaces as surfaces and a cue-guidance system for encoding conspicuous landmarks near the target.
(7) The capacity of granule-cell networks to separate overlapping patterns of activity on their inputs is adequate, with spatial variability in the secretion at synapses, but is improved if there is also temporal variability in the stochastic secretion at individual synapses, although this is at the expense of reliability in the network.
(8) The speed of visiting holes and the development of a preferred pattern of hole-visits did not influence spatial discrimination performance.
(9) Several types of neurons were differentiated on the basis of a study of neuronal activity in various parts of the cortex near the sulcus principalis during the execution of spatial delayed reactions by monkeys.
(10) At high luminances, the temporal, but not spatial, properties of this mechanism break down in a manner which had not been studied.Low-frequency inhibitory processThis process is manifest as a decrease in sensitivity from that of the simple excitatory process.
(11) The spatial resolution of a NaI(T1), 25 mm thick bar detector designed for use in positron emission tomography has been studied.
(12) In the longitudinal direction, however, spatial resolution of under slice thickness could not be obtained.
(13) These activities define both the polarity of the anterior-posterior (AP) axis and the spatial domains of expression of the zygotic gap genes, which in turn control the subsequent steps in segmentation.
(14) The different distribution and release of initiating enzymes for all these radical processes ensures the spatial and temporal control of their reactions.
(15) Proposed guidelines for future research include the use of conceptual rather than operational definitions of visual spatial ability, greater attention directed at separating spatial from nonspatial task components, and studies examining basic mechanisms underlying spatial vision.
(16) By modifying the spatial distribution of afferents to the network, we demonstrate that the same basic model functions properly in spite of afferents with nonuniform background firing rates.
(17) In the QHCl-sucrose condition components separated by the tongue's midline and those spatially mixed produced equal amounts of bitterness suppression.

(19) Models incorporating linear spatial-frequency- and orientation-selective channels explain many aspects of visual texture segregation.
(20) Colon and rectum, leukemia, and breast cancers were found to have very high positive spatial autocorrelation and high correlation with population density--a result contrary to previous findings in the West.
