PAWS-On-Science Outreach! April 2013

(Or, how some Velcro, crayons, and enthusiasm can go a long way to engage kids in science). Like many ecologists (and ecologists-in-training), members of the Olden Lab spend a good deal of time dissecting complex ideas in ecology and statistics. Although the work is exciting and rewarding in its own right, we also have felt a desire and responsibility to use our findings to help inspire and...

Sounding out the impacts of urbanization on lakes

If you are wondering why you seem stressed out lately, it could be the noise around you. A recent lab publication showed that environmental noise levels at freshwater lakes (the places we like to live, recreate, and relax) can be noisy – quite noisy, in fact – depending on the level of surrounding urbanization. Noise levels at urban lakes surpassed thresholds established by the Environmental...

Species distributions

Ecologists are challenged to reconcile the historical biogeography of long-evolved native species with the emerging and rapidly expanding patterns of recently arrived non-indigenous species. In contrast to terrestrial species, freshwater fishes are uniquely constrained because their ability to respond to environmental change is limited to movement defined by the connectivity of water. Our...

Environmental flows

The water needs of people and natural ecosystems are expected to become increasingly in conflict. Water managers are cognizant of these pressures, yet there remains a critical knowledge gap of the ecological tradeoffs associated with dam and flow management, including instream flows presently mandated in the Pacific Northwest and elsewhere. Our research aims to advance the science and develop...

Science and management

Biological invasions are well recognized a leading threat to the structure and function of ecosystems. Our research aims to advance the science, management and policy of invasive species with the goal of providing information on ecological impacts, elucidating introduction pathways and weighing the costs and benefits of considering prevention versus mitigation strategies for existing or...
