Evolution in an Urbanizing World
Fragmentation of habitat patches is one of many consequences that occurs due to urbanization. This fragmentation can lead to isolated populations that are completely surrounded by urban structures. This isolation can happen on relatively quick timescales, as quickly as 30 years! Due to the loss of habitat patches available for nesting, there can be plant-pollinator... Continue Reading →
Populations are often challenged to live in novel or rapidly changing environments. This is probably most clear in cities where new habitat is being created causing native species to encounter novel habitat features. But because of this, cities set the stage to help researchers understand the plastic and evolutionary shifts that occur in wild organisms.... Continue Reading →
Although I wasn't able to attend the meeting, the International Urban Wildlife Conference looks like it was a great success and I have enjoyed following along thanks to our great contributors and the hard work of co-editor Elizabeth Carlen. Here are some highlights: We Have Stickers! I drew these to pass out at the meeting... Continue Reading →
For most of us, our interest in urban ecology is rooted in the desire to better understand and conserve biodiversity. Once researchers better understand the science behind issues facing our urban species, the next step is engaging the wider public on how to beset conserve these species. This theme was present almost every talk I... Continue Reading →
Following the plenary at IUWC 2019, this session focused on integrating urban ecology research with community engagement. The speakers here built on some of the ideas expressed by Chris Schell previously on this site. Pigeons & Passers-by Elizabeth Carlen, an editor for this blog and PhD student in the Biological Sciences department at Fordham University... Continue Reading →
Suboptimal movement across the urban landscape can lead to injury or death and, thus, has a high fitness cost. Many cities have developed wildlife corridors that allow animals to move through the urban matrix while reducing their chances of being struck by a vehicle. But what if impervious surfaces, such as bike paths, can act... Continue Reading →
This session included three very different community science projects--from otters in Singapore to cats around the world! Otters! Philip Johns, of Yale-NUS College, studies the foraging behaviors in urban smooth-coated otters in Singapore. Singapore is very urban, and all of its waterways are highly modified--similar to those in Los Angeles. Despite this, about 18 families... Continue Reading →
Aaron Anderson is a Ph.D. student in Horticulture at Oregon State University, where he works in the Garden Ecology Lab. Aaron’s project was inspired by the Garbuzov and Ratnieks paper entitled ‘Listmania: the strengths and weaknesses of lists of garden plants to help pollinators’. In this paper, the authors note that many pollinator plant lists... Continue Reading →
A critical issue when managing for habitat in urban areas is habitat size. What is the minimum viable patch size for a species of concern? Can multiple smaller patches, such as yards and parks, collectively “scale up” to provide connected, suitable habitat? Michael Vermeulen, an M.S student at Portland State University, spoke at IUWC2019 about... Continue Reading →
Raptors are making a comeback in cities around the world, thanks to the discontinuation of DDT. We've highlighted raptors including Red-tailed Hawks and Peregrine Falcons previously in our Urban Observation of the Week. Within cities, pigeon and rat populations provide ample food and researchers in many cities are investigating what resources and landscape variables dictate... Continue Reading →
Urban yards have a large potential for providing habitat, and important considerations when studying these spaces are the tritrophic interactions between plant species, herbivores, and predators. Dr. Marion Dresner, Professor at Portland State University, has spent years studying these interactions in backyard habitats and is particularly interested in understanding how the management of backyards provides...

Dr. Gail Langellotto, Professor of Urban and Community Horticulture at Oregon State University, was the first speaker in the "Urban Garden Ecology" section at the 2019 IUWC. Dr. Langellotto has been conducting research in garden ecosystems since her first faculty job at Fordham University. An entomologist by training, when she moved to the Bronx she... Continue Reading →
If you live in a city you may not realize that urban populations of bats are all around you. But Liza Lehrer and Shannon Pederson, who work on urban bats, know that bats are common in cities, even if you don't always see them. Lehrer started off by describing how bats are under threat due...

The International Urban Wildlife Conference kicked off Monday morning in Portland, OR with a Plenary Session titled "Collaboration and Conservation: Applications to Urban Wildlife" featuring talks by Dr. Chris Schell, Deeohn Ferris, and Bob Sallaniger followed by a panel discussion. Dr. Schell, Assistant Professor of Urban Ecology at the University of Washington, Tacoma and Life... Continue Reading →
The 2019 International Urban Wildlife Conference will take place in Portland, Oregon from June 2nd-5th. This meeting is a great chance to connect with other scientists studying urban evolution and hear about the wide range of research that is being conducted in urban environments. Talk submission has already closed, but registration is open until May... Continue Reading →
