Behavioural thermoregulation and activity patterns in the green sunfish, Lepomis cyanellus
Animal Behaviour
|February 1, 1975
Abstract:
Behavioural thermoregulation and locomotory activity of green sunfish were examined in a temporal temperature-gradient apparatus. Green sunfish actively avoided temperatures exceeding 30.3 degrees C and below 26.5 degrees C and had a median preferred temperature of 28.2 degrees C. Temperature preference did not vary significantly during the diel period even though locomotory activity patterns were markedly crepuscular. Activity was stimulated by the change in illumination levels at dawn and dusk.

01:06Fixed Action Patterns
A fixed action pattern (FAP) is a specific, hard-wired sequence of behaviors that occurs in response to an external stimulus, called a sign stimulus. The behavior is “fixed” because it is essentially unchangeable—proceeding similarly across individuals of a species every time it occurs.
02:32Osmoregulation in Fishes
When cells are placed in a hypotonic (low-salt) fluid, they can swell and burst. Meanwhile, cells in a hypertonic solution—with a higher salt concentration—can shrivel and die. How do fish cells avoid these gruesome fates in hypotonic freshwater or hypertonic seawater environments?

Temperature-Dependent Growth of Brook TroutThe growth of brook trout is closely influenced by water temperature. Experimental data demonstrate how trout weight changes over a 24-day period in response to varying water temperatures. At lower temperatures, such as 15.5 degrees Celsius, brook trout show significant weight gain. However, as the temperature increases, the amount of weight gained steadily decreases. At the highest temperature measured, 24.4 degrees Celsius, trout experience a net...
