1. Morphological adjustment among flowers and their pollinators is an essential component of life in ecosystems. This leads to one of the most beautiful mutualisms in nature: pollination by animals. Flowers provide energetic nectar to visitors, which in return carry the pollen from one flower to another, helping the plant in reproduction. However, there are floral visitors whose body does not match the morphology of the flower. Unable to access the precious nectar, the potential pollinators turn in to robbers and make a hole in the corolla tube where they can extract the nectar. This usually damages the flower, but sometimes a clumsy robber can inadvertently pollinate the flower. This video shows that when we explore nature with an open eye, we often realize the many “human” behaviours have been used by animals for millions of years.

    El ajuste morfológico entre algunas flores y sus polinizadores es, en muchos casos, espectacular. Esto da lugar a una de las relaciones mutualistas más bonitas de la naturaleza: la polinización por animales. Las flores ofrecen energético néctar a los visitantes y estos a cambio transportan el polen de unas flores a otras, ayudando a la reproducción de las plantas. Sin embargo, hay visitantes florales que, incapaces de acceder a tan preciada recompensa, optan por realizar una perforación en el tubo de la corola, cerca de donde se encuentra escondido el néctar. Esto suele tener efectos nefastos para la planta. Sin embargo, hay ocasiones en las que la torpeza del ladrón tiene un efecto positivo para la planta…

  2. Led by a well-known personage, in this video we can delve a little deeper into the fascinating world of heterostyly, a genetic polymorphism consistent in the presence of two or three floral forms within the same species of plant. Through a fun animation we have the chance to learn a little more about ... the sex of some flowers.
    The video also shows a new methodological tool developed by the Laboratory of Ecology and Evolution at the University of Vigo to study ... the sex of the plants!
    The tool is available at:

  3. De la mano de un conocido personaje, en este vídeo nos podemos adentrar un poco más en el fascinante mundo de la heterostilia, un polimorfismo genético consistente en la presencia de dos o tres formas florales dentro de una misma especie de planta. Mediante una divertida animación tenemos la posibilidad de aprender un poquito más sobre … el sexo de algunas flores.
    En el vídeo se muestra además, una nueva herramienta metodológica elaborada por el Laboratorio de Ecología y Evolución de la Universidad de Vigo para estudiar ... el sexo de las plantas!
    La herramienta está disponible en:

  4. En 1830, John Henslow introduciu ao seu discípulo Charles Darwin no fascinante mundo dos polimorfismos florais. Concretamente presentoulle o caso dalgunhas especies de plantas hermafroditas que teñen dúas formas florais que difiren na altura e disposición das estruturas sexuais femininas: os pistilos. Nunha forma floral, os estigmas encóntranse localizados por enriba das estruturas masculinas (os estames), mentres que na forma oposta, os estigmas se encontran localizados debaixo dos estames.
    Tratar de descifrar a orixe e as consecuencias deste fascinante mecanismo reprodutivo que presentan algunhas especies de plantas contribuíu, sen dúbida, a modelar ese carácter curioso e crítico que levou ao mozo Darwin a formular anos máis tarde a súa hipótese da Selección Natural.
    Dende entón, unha pléiade de investigadores seguen tratando de descifrar os misterios que rodean a este refinado mecanismo reprodutivo.
    Neste vídeo explícase en que consiste a Heterostilia: un polimorfismo floral que atraeu a atención de Darwin ata o punto de que dedicou un libro ao seu estudo. No vídeo faise un repaso contestando ás preguntas de ¿Qué é?, ¿Para que serve? ¿Cómo se orixina? o ¿Cómo se pode estudar?
    A heterostilia é un polimorfismo consistente na presenza de dous ou tres formas florais dentro dunha mesma especie de planta. As vantaxes deste sistema de reprodución, así como a súa orixe son temas de controversia científica. No vídeo explícanse as achegas que fixo neste tópico o Grupo de Ecoloxía e Evolución da Universidade de Vigo (webs.uvigo.es/plantecology/)

  5. In 1830, John Henslow introduced his pupil Charles Darwin in the fascinating world of floral polymorphisms. Specifically he presented him the case of some plant species hermaphrodites having two floral forms that differ in height and arrangement of female sexual structures: the pistils. In a floral morph, stigmas are located above the male structures (stamens), while in the opposite morph, the stigmas are located below the stamens.
    Trying to unravel the origin and consequences of this fascinating reproductive mechanism that some plant species have, undoubtedly contributed to shaping the curious and critical character that led the young Darwin to formulate years later his hypothesis of Natural Selection.
    Since then, a myriad of researchers are still trying to decipher the mysteries surrounding this refined reproductive mechanism in some plants.
    This video explains what is heterostyly: a floral polymorphism that attracted Darwin´s attention to the point that he devoted a book to its study. The video gives an overview answering questions as: What is heterostyly?, What good is this sexual system? How did it originate? or How can we study it?
    Heterostyly consisting polymorphism is the presence of two or three floral shapes within the same plant species. The advantages of this system of reproduction, and its origin are matters of scientific controversy. The video explains the contributions has made in this topic the Group of Ecology and Evolution at the University of Vigo
