Terrestrial Ecosystem Ecology Lab: Dr. Paul Grogan

Lab mottos:
Quality transcends Quantity
Soil is not 'dirt'!
All components of nature have intrinsic value irrespective of their usefulness to humans1
Nothing in biology makes sense except in the light of evolution2... and very little in evolution makes sense except in the light of ecology3
Scale, scale, scale - it's the fundamental context that underlies all scientific understanding
Enjoy - It's later than you think
A thing is right when it tends to preserve the integrity, stability, and beauty of the biotic community. It is wrong when it tends otherwise4
Maybe the experiment of making apes smarter is an evolutionary dead-end5
Maybe our greatest need now is not more knowledge, but more wisdom6
Carpe diem - but not at the expense of others - other days, and other people

Ecosystem ecology is the study of species’ interactions with each other, and with their physical environment, all as parts of an integrated system.  It is a new and rapidly advancing branch of science that stresses the interconnected nature of our world.  Furthermore, humans and human activities are an inherent part of ecosystems, and therefore ecosystem-level ecological perspectives and methodologies are at the heart of much of the global change research agenda.  Researchers in ecosystem ecology are contributing fundamental science inputs into a wide range of current environmental issues including effects of changing land use and management practices, impacts of climate change and mitigation strategies, the functional significance of biodiversity, and assessments of sustainable resource use from both environmental and socio-economic perspectives.

Dr. Paul Grogan is Professor of Plant and Terrestrial Ecosystem Ecology in the Department of Biology at Queen's University, and was awarded a Canada Research Chair (Tier II) in the ecology of arctic ecosystems and their sensitivity to climate change (2003-2013).
