Factors Which Regulate The Species Specific Behaviours In Birds, Fish And Primates

Species-specific behaviours are instinctive and adaptive actions unique to each species, helping them survive and reproduce. These behaviours are regulated by a mix of internal biological factors (genes, hormones, instincts) and external environmental cues (climate, food, social context).

Factors Of species Specific Behaviours -

1. Fish

Internal (Biological):
– Genetic instincts guide schooling and spawning.
– Hormonal changes (e.g., gonadotropins) regulate breeding cycles.
External (Environmental):
– Water temperature and oxygen levels influence activity.
– Availability of food and presence of predators shape movement and grouping.
– Function: Ensures survival, reproduction, and predator avoidance.

2. Primates

Internal (Biological):
– Instinctive drives for grooming and social bonding.
– Neurochemical rewards (endorphins, oxytocin) reinforce affiliative behaviours.
External (Environmental):
– Social hierarchy and group size regulate grooming and cooperation.
– Stress or conflict increases grooming to restore harmony.
– Function: Maintains hygiene and strengthens social cohesion.

3. Birds

Internal (Biological):
– Genetic programming fixes migration routes.
– Hormonal changes and circadian rhythms regulate timing.
External (Environmental):
– Photoperiod (day length), climate, and food availability trigger migration.
– Function: Secures food and favorable climate for survival.
