摘要

摘要环境变化会导致鱼类的生理变化，从而影响某些行为模式。我们评估了水温对雄性淡水天使鱼（Ptephyllum scalare）攻击行为的影响。我们将两人一组置于三种水温条件下：低（23.8±0.8°C）、中（27.9±1.2°C）和高（31.7±1.0°C），每个条件下重复八次。我们评估了战斗的潜伏期、攻击性互动频率和领土防御。与中等温度相比，在低温和高温下，攻击行为的表现有所减少（P<0.05）。因此，水温会影响攻击动机和领地的建立，因为接近物种最佳温度（27.9±1.2°C）的温度会有利于亚马逊观赏慈鲷物种P.scalare的社会竞争。

Water temperature modulates social behavior of ornamental cichlid (Pterophyllum scalare) in an artificial system

ABSTRACT Environmental changes can cause physiological alterations in fish, which may affect some behavioral patterns. We evaluated the effects of water temperature on the aggressive behavior of male freshwater angelfish, Pterophyllum scalare. We subjected pairs to three water temperature conditions: low (23.8 ± 0.8°C), medium (27.9 ± 1.2°C), and high (31.7 ± 1.0°C), with eight repetitions each. We assessed latency to fighting, aggressive interaction frequency, and territorial defense. In low and high temperatures there was a reduction in aggressive behavior exhibitions in comparison to medium temperatures (P < 0.05). As a result, water temperature can influence aggressive motivation and territorial establishment, given that temperatures closer to species optima (27.9 ± 1.2°C) can favor social contests for an Amazonian ornamental cichlid species, P. scalare.
