Resumen

Las sequías extremas tienen efectos negativos en la diversidad y el funcionamiento de los bosques. Sin embargo, a nivel de especie, estos efectos aún no están claros, ya que las especies varían en su respuesta a la sequía a través de combinaciones de rasgos funcionales específicos. Utilizamos registros demográficos a largo plazo de 21.821 árboles y extensas bases de datos de rasgos para entender las respuestas de 338 especies de árboles de bosques secos tropicales a ENSO2015, el evento más seco en décadas en el norte de Sudamérica. Las diferencias funcionales entre las especies se relacionaron con el compromiso entre seguridad y eficiencia hidráulica, pero inesperadamente, las especies dominantes se caracterizaron por una alta inversión en tejidos de hoja y madera, independientemente de su hábito fenológico. A pesar de las amplias combinaciones de rasgos funcionales, la mortalidad de los árboles estuvo más extendida en el espacio funcional que el crecimiento de los mismos, donde las especies menos adaptadas mostraron balances de biomasa netos más negativos. Nuestros resultados sugieren que si las condiciones de sequedad aumentan en este ecosistema, la funcionalidad ecológica y la ganancia de biomasa se verían reducidas.
