Title: Experimental warming reduces pollen performance and nectar production in a tropical shrub

Short description:<br>This package includes four CSV datasets. Files include records of nectar volume and concentration, pollen viability, pollen tube length estimates, fruit counts (including aborted fruits), and seed counts. Flowers were exposed to two temperature treatments, ambient temperature and an increase of 3.5°C.<br>Recommended citation:García‑Robledo, C. et al. (2025).
