In that season, shortened days, diminishing and perhaps unpredictable food supplies, and inclement weather all present special challenges for foraging and acquiring energy.

Micha? Kuciapskits. Indeed, critical inquiries into the origins of mating systems provided some of the “cornerstone” of the field of behavioral ecology e.g., Crook, 1964; Verner, 1964; Orians, 1969, 1972). Classically, mating systems were defined with respect to the number of mates obtained by males and females per作者: nitroglycerin 時(shí)間: 2025-3-23 20:07
