Trade off isocline
Regardless, the effects of temperature on rates (e.g., maturation, metabolism, growth), traits (e.g., body size, total reproductive investment) and links between traits (e.g., trade‐offs) can alter the underlying ability of organisms to respond to predation. Moreover, if both prey and predators behave adaptively, the neutral stability can be completely lost, and a globally stable equilibrium would appear. This is because prey and/or predator switching leads to a piecewise constant prey (predator) isocline with a vertical (horizontal) part that limits the amplitude of oscillations in prey and An equalizing trade-off is a negative interspecific correlation between two or more traits, which makes interspecific differences in fitness smaller than they would have been otherwise (Chesson 2000a). - An interaction in which both species benefit (increase their survival and reproduction) ex) clownfish and sea anenome's- clownfish drives off butterfly fish which is a predator, and the anenomes tentacles protect the clownfish by stinging their predators ex) crabs and coral.
By pitting two species of worms against each other at varying densities, researchers have determined that the zero growth isocline of species A is always above that of species B. This means that a. A will always exclude B. b. B will always exclude A. c. one species will exclude the other depending on the initial conditions.

The increase in a predator's reproduction in response to an increase in the consumption of prey is known as the predator's ________ response. numerical. A type ________ functional response describes the per capita rate of predation, which increases linearly with prey density. The utility isocline captures the trade-offs between conservation objectives, measured in terms of biodiversity, and agricultural production that provide equal benefits, i.e., constant utility. Such isoclines can be drawn for different levels of utility. • the isocline for each species, indicating which one is for Species 1 versus Species 2 • the equilibrium point • label both the x and the y axis (but not specific values of where isoclines intersect axes) N 1 N 2 Life history trade-off E B.

R o = 1) of an annual plant where each female produces 10 seeds (seeds for female plants, we ignore males here). Consider seeds as babies (age 0) and start with a cohort of 100 total seeds. Hint: because we are dealing with an annual organism, generation time = 1, hence R o = λ . Trade-offs among ecosystem services can generate conflicts in natural resource management, development, and planning. Trade-offs can occur because of inherent constraints of the biological, ecological, and physical system (called “biophysical” hereafter).
