| Research Description |
Shahid Naeem studies the ecological and environmental consequences
of biodiversity loss. He is interested in how changes in the distribution
and abundance of plants, animals, and microbes, affect how ecosystems function
and, by extension, how ecosystems services are affected. His work combines
theoretical, observational, and experimental studies under field and laboratory
conditions, to uncover the mechanistic bases for the impacts of biodiversity
loss on ecosystems. His work has demonstrated how the loss of species from
ecosystems affect their ability to resist invasion by other species, affect
production and nutrient cycling, and affect the reliability and stability
of ecosystems. He is actively involved in bringing the science of biodiversity
and ecosystem functioning to conservation, restoration, and policy development. |

| Current Research |
Currently, Dr. Naeem's field work concerns how extrinsic factors,
such as soil fertility and disturbance, interact with plant biodiversity
to regulate the spread of invasive plant species in old fields at the Cedar
Creek LTER in Minnesota. He plans to expand this work to Black Rock Forest
here in New York. His theoretical work examines how mathematical models
developed for reliability engineering can be used for understanding how
the reliability of ecosystems are affected by biodiversity loss, global
change, management, and environmental degradation. His synergistic work
involves coordinating a group effort to predict the local, regional, and
global impacts of biodiversity loss across a wide variety of ecosystems. |
