Which of the following groups of species is most likely to experience range-shift rates fast enough to "keep up" with warming temperatures? Trees in the mountains, where climate velocities are low Trees on the plains, where climate velocities are high. Large mobile predators in the mountains, where climate velocities are low. Large mobile predators on the plains, where climate velocities are high. Q5.26. Which of the following statements about the effects of climate change on phenology is false? 45 Climate-induced changes in phenology have been documented in many taxa The timing of temperature-cued spring events is shifting earlier in the year. Acclimation or evolution could produce a change in phenology. Climate-induced changes in phenology are more likely when events are cued by day length instead of temperature 47 Q5.27. Snowshoe hares (pictured below) rely on camouflage to avoid predation. Their coats change color to match the environment. In Seeley Lake, Montana, climate change is producing shorter winters with decreased snow cover. As a result, many hares turn white n the fall before snow cover arrives (middle image below). Some ecologists suggest thatExplanation / Answer
Q5.25
Answer: option (c) is correct. large mountain predators are more active during hot weather when climate speed is low.
Reason: in the mountains, the climate is more temperate, therefore predators should take advantage of the moments of warm weather to hunt and animals can hardly adapt to environments with shifting temperatures.
Hence, option (c) is correct.
Q5.26
Answer: option (c) is correct. evolution can make no changes in phenology
Reason: living beings adapt to the climate therefore evolve, ie change their phenomenology and it should be phenology can produce a change to the evolution of organisms.
Hence, option (d) is correct.
Q5.27
Answer: option (d) is correct.
Reason: newcomers will mate with the old inhabitant hares making a new offspring which is genetically produced by both making them adapt to climate change or if a new population of hares arrives there will be more genetic variability and that trait may evolve and make the hares change their winter coat faster.
Hence, option (d) is correct.
Q5.28
Answer: option (b) is correct. a range shift
Reason: Simply because by definition morphological acclimationis the process in which an individual organism adjusts to a change in its environment (such as a change in altitude, temperature, humidity, photoperiod, or pH).
Hence, option b(b) is correct.
