The silent force in the food web

Addition of parasites (red spheres) visibly increases connectivity of species in this representation of an Arctic food web. Studies of food webs fascinate community ecologists. There seems to be a never-ending supply of interactions to observe, analyze and use in predictions. From the largest apex predators, feeding once a week, to the smallest alga, constantly converting sunlight to energy, there’s…
