Descripción del proyecto
La estrategia de polinización de las abejas
Comprender los patrones de pecoreo y las interacciones de las abejas es clave para los ecólogos y los economistas. En el proyecto BEE-MOVE, financiado con fondos europeos, se empleará un método interdisciplinario, que combina el comportamiento de los polinizadores y la ecología vegetal, para vincular los movimientos de los polinizadores y la eficacia de polinización. Un nuevo sistema de radar registrará y analizará los movimientos individuales de cientos de abejas pecoreadoras de forma simultánea. Además, se emplearán radares y plantas robóticas para estudiar cómo las abejas buscan y aprovechan los recursos tróficos en varios kilómetros cuadrados. Esta información se introducirá en modelos informáticos basados en agentes para estudiar la influencia de las estrategias espaciales de las abejas en la eficacia de polinización. Los resultados servirán para diseñar intervenciones prácticas de conservación, agricultura sostenible y desarrollo verde a fin de ayudar a frenar el declive de los polinizadores.
Objetivo
How pollinators, such as bees, exploit plaHow pollinators, such as bees, exploit plant resources is a fundamental question in biology, with deep ecological, economical and societal consequences. When foraging on flowers, pollinators transfer pollen and mediate the reproduction of plants on which most animals (including us humans) rely on. Understanding the spatial foraging strategies and interactions of pollinators across the landscape is thus a critical scientific challenge to discover their influence on plant mating patterns and pollination efficiency. BEE-MOVE will use an interdisciplinary approach to mechanistically link pollinator movements to pollination efficiency at field scales, thereby crossing boundaries between research on pollinator behaviour and plant ecology. I will focus on two key pollinators worldwide: the buff-tailed bumblebee and the Western honey bee. 1) I will develop a new radar system to record and analyse the individual 3D movements of hundreds of bees foraging simultaneously. 2) I will use arrays of communicating radars and robotic plants to study how bees search and exploit food resources in field setups of several square kilometres, by manipulating key environmental factors such as the density of bees, the 3D distribution of plants, and the nutritional content of nectars and pollens. 3) From these observations, I will build computational agent-based models to investigate the influence of bee spatial strategies on pollination efficiency. Critical experiments will test model predictions in populations of natural plants. The dialogue between observations and simulations will create a positive feedback towards a robust, multi-level understanding of plant-pollinator interactions at the scale of landscapes. In addition to exploring entirely new grounds in pollination ecology, my results could be used to design practical interventions for conservation, sustainable agriculture and green development in the worrying context of pollinator declines.
