Sentence examples for mortality at which from inspiring English sources

Without evolution in either predator or prey, the predator goes extinct when additional mortality imposed by environmental change exceeds 0.16 (≈ 0.16; Fig. 2A); adding predator evolution slightly increases the maximum mortality at which the predator can persist, due to an increase in y (≈ 0.19: Fig. 2B).

In contrast, prey evolution leads to an increase in the maximum mortality at which predators can persist, because the prey population decreases defense (by decreasing x value) to increase its intrinsic rate of increase: the predator does not go extinct when me < 0.3 (Fig. 2C).

Therefore, the relationship between, the maximum mortality at which the predator can persist, and y, the predator's counter-adaptation to prey defense, is: (3) where, and is an increasing function of y (because and the right-hand side of d y/d t in eqn (2) is zero at the coexistence equilibrium).

As abrupt environmental change increases predator mortality and eventually causes its extinction, an important value for evaluating evolutionary rescue is the maximum value of predator mortality m at which predator can persist (that is, its abundance is nonzero).

There is no accepted mortality level at which we designate dogs to be geriatric, or even senior.

The parameter is defined as the level of fishing mortality (F) at which the increase in yield for one unit of effort is one tenth of the increase experienced at very low levels of effort.

In the coevolution model, the maximum value of predator mortality m at which predator abundance is nonzero now includes m1: = rbf/ k – m1.

The prey population evolves to reduce defense (x decreases) when m increases, because at a stable equilibrium, the right-hand side of d x/d t in eqn (1) becomes negative with decreased P. Prey evolution therefore increases, the maximum predator mortality rate at which the predator population is viable; this increase in is the quantitative contribution of indirect evolutionary rescue.

Adult survival is equal to φ when z = 0, which corresponds to the current level of natural mortality and the current rate of mortality at sea, which is unknown in our analysis.

Three isolates belonging to S. feltiae caused 70% average mortality at 25 °C which is similar to our study (Yoshida, 2010).

In contrast to the ALIVE study, several centres have reported their 28-day mortality at 40%, which represents an improvement from the 60% of 10 years ago.
