the idea of a zero isocline is a line that represents all of the combinations of species 1 and 2 (which are points in 2 dimensional space) that result in one species having a growth rate (dN/dt) of zero.
What is the zero isocline for a species?
Any given point along, for example, species 1's zero isocline represents a combination of abundances of the two species where the species 1 population does not increase or decrease (the zero isocline for a species is calculated by setting dN/dt , the growth rate, equal to zero and solving for N ).
What are isoclines in math?
Isocline. Isoclines are often used as a graphical method of solving ordinary differential equations. In an equation of the form y' = f ( x, y ), the isoclines are lines in the ( x, y) plane obtained by setting f ( x, y) equal to a constant. This gives a series of lines (for different constants) along which the solution curves have...
How are the intersections of the isocline for species 2 similar?
The intersections of the isocline for species 2 are essentially the same, but on different axes. These two graphs illustrate what happens to a population when it is below or above its isocline, but they only account for one isocline at a time.
How do you find the isocline on a population graph?
In each graph, the solid yellow line represents the isocline of species 1, and the dashed pink line represents the isocline of species 2. The thick black arrows represent the joint trajectory of the two populations, and the thinner colored arrows indicate the trajectories of the individual populations.

This is the no growth I supplied for species 2.
What is an isocline in math?
The term isocline derives from the Greek words for "same slope." For a first-order ordinary differential equation is, a curve with equation for some constant is known as an isocline. In other words, all the solutions of the ordinary differential equation intersecting that curve have the same slope.
What is an isocline in ecology?
isocline A line joining points on a graph at which combinations of resource levels or population densities produce a similar rate of population growth for a particular species. A Dictionary of Ecology.
What is an isocline map?
isoclinenoun. A line on a map linking places with the same magnetic dip.
How do you find isocline?
Definition of isocline. An isocline is a set of points in the direction field for which there is a constant c with dy dx = c at these points. Geometrically, the direction field arrows at the points of the isocline all have the same slope. Algebraically, we find the isocline for a constant c by solving f(x, y) = c.

What is a zero net growth isocline ZNGI )? Explain what it represents biologically?
zero-growth isocline. this represents the combined values of population size for two species at which the population growth rate of the respective species is zero. carrying capacity. the zero-growth isocline occurs when combined population sizes are equal to this value of the species.
What will be the outcome of the competition if zero growth isocline of species 2 lies outside to zero growth isocline of species 1?
Conclusion: For any x-y value of N1 and N2 that is above the Species 2 zero growth isocline, N2 will decrease.

What are ISO Heights?
An isoheight or isohypse is a line of constant geopotential height on a constant pressure surface chart. Isohypse and isoheight are simply known as lines showing equal pressure on a map.
What does a zero isocline represent?
For each species there is a straight line on the graph called a zero isocline . Any given point along, for example, species 1's zero isocline represents a combination of abundances of the two species where the species 1 population does not increase ...
Why does the population size increase in the isocline?
Below and to the left of the isocline the population size increases because the combined abundances of both species are less than the carrying capacity of the one , while above and to the right the population size decreases because the combined abundances are greater than the carrying capacity.
