What is temporal variation in biology?
Temporal variation is a powerful source of selection on life history strategies and functional traits in natural populations. We found strong signatures of genetic, environmental (plastic), and developmental variation in four traits that can influence plant hydrological responses.
What is temporal variation in geography?
Temporal variations appear in the time series of amplitudes and phases of the observed ACROSS signals in the case that the ACROSS seismic source is settled on the ground surface; From: Handbook of Geophysical Exploration: Seismic Exploration, 2010.
What is the difference between spatial and temporal variation?
Spatial refers to space. Temporal refers to time. Spatiotemporal, or spatial temporal, is used in data analysis when data is collected across both space and time. It describes a phenomenon in a certain location and time — for example, shipping movements across a geographic area over time (see above example image).
What is temporal and spatial variability?
A basic difference between temporal and spatial kinds of variability is the types of correlations that occur in the system. Under temporal randomness, mutants are spatially correlated with each other (they simply have equal fitness values at a given moment of time; the same holds for wild-types).
What do you understand by spatial and temporal variability in rainfall explain by using data pertaining to India?
Answer: Rainfall in India is highly uneven over a period of time in a year. The average annual rainfall is about 125 cm, but it has great spatial and temporal variations. Temporal variation: The distribution of rainfall varies temporally as per an annual cycle of seasons.
What are spatial variations?
A difference or variation (in terms of population, population density, gross domestic product (GDP), life expectancy) over an area of the earth’s surface.
What is a temporal pattern?
Definition of temporal pattern : the unitary impression produced by a succession of stimuli (as in a melody or rhythm)
What is the difference between temporal and spatial summation?
The difference between temporal Summation and spatial Summation is that temporal Summation involves a single presynaptic neuron, whereas spatial Summation involves multiple presynaptic neurons. Spatial Summation comes into existence when an action potential is triggered by inputs and information from multiple neurons.
What do you understand by spatial and temporal Variability in rainfall?
Rainfall Variability is defined as degree of rainfall amount vary over an area , called Spatial Variability or over a time called Temporal Variability. Recent Study shows that there is decrease in spatial variability of average rainfall over river basin.It has broad significance in Indian Climate like.
What does temporal variability mean?
(b) Under pure temporal variation, factors vary from one time to another but are constant across space. (c) Spatial and temporal variation can occur together; in this case, the factors change from one time to another but remain constant across space.
What is temporal variability in rainfall?
The variation of rainfall amounts at various locations across a region for a specific time interval. ( Time does not vary.) Example: Annual average precipitation, Northern California. Temporal Variability. The variation of rainfall amounts at a given location across a time interval.
How is the degree of temporal variation related?
The degree of temporal variation is related to the degree of karstification, mantle thickness, wet-dry cycles and surface water recharge to the aquifer, and the proportion of conduit to diffuse flow.
How is the degree of temporal variation related to karstification?
The degree of temporal variation is related to the degree of karstification, mantle thickness, and the proportion of conduit to diffuse flow. For example, nitrate concentrations in groundwater generally increase following seasonal applications of fertilizers and subsequent recharge of the groundwater system.
How does temporal variation affect isotopic hydrograph separation?
Temporal variations in the tracer concentration of the water input during the course of events is a problem in isotopic hydrograph separation and may prevent accurate separations (cf. discussion on the variation of the isotopic composition of the rainfall in Chapter 10 ).
How are nitrate concentrations related to temporal variation?
Temporal variations in nitrate concentrations in groundwater and springs reflect the interrelation of several important hydrogeologic, geochemical, land use, and climatic factors. The degree of temporal variation is related to the degree of karstification, mantle thickness, and the proportion of conduit to diffuse flow.
