In contrast to the situation with incubation period, explanations for variation in hatching synchrony invoke many factors and plausible causes (Clark and Wilson, 1981; Slagsvold, 1986; Slagsvold and Lifjeld, 1989; Slagsvold, 1990; Magrath, 1990; Mock and Schwagmeyer, 1990).

In these cases social behavior is plastic and changes rapidly with environmental conditions (e.g., Myers, 1980; Davies and Houston, 1981; Tye, 1986), and the function of specific behavioral patterns is often relatively easy to infer.optic-nerve 发表于 2025-3-22 21:16:01
