Humpback Dolphin (Genus Sousa) Behavioural Responses to Human Activities

Area of Science:

• Marine Mammal Behavior
• Conservation Biology
• Human-Wildlife Interactions

Background:

• Humpback dolphins (genus Sousa) inhabit vulnerable coastal areas.
• Coastal distribution increases susceptibility to human disturbances.
• Research often overlooks indirect behavioral effects of human activities on dolphins.

Purpose of the Study:

• To review behavioral responses of humpback dolphins to human activities.
• To identify knowledge gaps for informed conservation and management.
• To provide examples from diverse taxa on animal behavioral responses.

Main Methods:

• Literature review of scientific studies on humpback dolphin behavior.
• Analysis of impacts from marine vessel traffic, tourism, fisheries, noise, and habitat alteration.
• Synthesis of data to identify research and information gaps.

Main Results:

• Human activities like vessel traffic and tourism can alter humpback dolphin behavior.
• Cetacean-fishery interactions and noise pollution also pose indirect threats.
• Significant data gaps exist in understanding these behavioral responses.

Conclusions:

• Understanding behavioral responses is crucial for mitigating human-wildlife conflict.
• Behavior-based management strategies are needed for humpback dolphin conservation.
• Further research is essential to fill identified data gaps and support conservation efforts.
