Prompt
Generate a realistic portrait of Stephen P. Hubbell, a middle-aged American environmentalist and botanist, in a setting that reflects his work in tropical forest ecology, possibly surrounded by lush greenery or with a subtle background that hints at his connection to the natural world, dressed in attire suitable for a professional in his field, such as a button-down shirt and khaki pants, with a thoughtful expression that conveys his dedication to his work, including the Unified Neutral Theory of Biodiversity, in a style that is reminiscent of a photograph taken in a serene outdoor setting.
