How disturbances change ecosystems

Biodiversity—short for biological diversity—makes the world go round, powering the ecosystem that supports life.

MFNC’s November 3 speaker via Zoom, Alberto Suarez-Esteban—local farmer, instructor and researcher; a biologist by training and a passionate naturalist—knows well how disturbances change ecosystems.  As well as teaching “Ecosystem and Environmental Change” at Carleton University, he has developed a diversified, agricultural operation at Nature’s Apprentice Farm in Pakenham, where he and his partner Joanna produce fresh flavourful vegetables that also regenerate the land where they’re grown.

Along with such hashtags as #regenerativeagriculture #farmingforwildlife#farmingforthefuture, #ecosystems #biodiversity  and #microfarm, the photos and explanations that accompany Nature’s Apprentice Farm Facebook posts of their varied produce provide a learning experience that includes wildlife.

One such photo shows Alberto prepping #notill hedgerows for creating habitat for all kinds of creatures.

Alberto Suarez-Esteban—local farmer, instructor and researcher knows well how disturbances change ecosystems.

Arms full of salad turnips and radishes, Alberto is proud of his roots; his pride also extends to Spain, where he was born and raised and earned his PhD.  And it is to this country that we will follow him on November 3 as he unravels the unexpected consequences of roads in a Mediterranean ecosystem.

Roads are usually known by their negative ecological impacts, he notes.  “However, they may have other surprising effects. The presence of dirt roads and firebreaks can alter the relationships between carnivorous animal and plant species, making them stronger in some areas and weaker in others.”

And completing the study, such research reinforces the need to “evaluate the ecological responses of plants, birds and other organisms to human disturbances with the goal of informing sustainable use and preservation of terrestrial ecosystems.”
