The document outlines the planning and production process for a video project from October to February. It involved choosing songs, researching genres, analyzing other videos, developing initial ideas and storyboards, casting actors, determining filming locations, filming, checking footage, further filming, editing, adding effects, developing evaluation questions, and finalizing an overview with changes added. The process included multiple cycles of planning, production, review and refinement.
Red deer stags communicate size and fitness through roars, whose formant frequencies provide an honest signal correlated with age, weight, and reproductive success. Fundamental frequencies do not reliably indicate these traits. Formants are anatomically constrained by vocal tract length, ensuring only larger, older stags can produce certain low frequencies. This suggests formants evolved to honestly signal a stag's strength and fertility to rivals and mates.
