An introduction to the city spider Spiders are the most diverse and abundant terrestrial predators on earth. This group of species is, in turn, a crucial contributor to the earth's ecosystems as we know them: they control insect populations directly, which indirectly changes plant diversity and productivity. Since many of the earths ecosystems are under... Continue Reading →
Urbanizationโs Hidden Pleiotropic Effect on Pigeon Plumage Color and Blood Cholesterol
Some fries left on the ground, a half-eaten sandwich, or some breadcrumbs kindly given by someone on a park bench. Pigeons (Columba livia) in the city don’t shy away from eating human-derived foods. Although most pigeons are eager to eat our food scraps, this behaviour has been linked to a likely downside: the urban lifestyle... Continue Reading →
New Lit Alert: How does urbanization affect natural selection?
How does urbanization affect natural selection? Anne Charmantier, Tracy Burkhard, Laura Gervais, Charles Perrier, Albrecht I. Schulte-Hostedde & Megan J. Thompson Abstract Urbanisation is one of the most significant contributors to the Anthropocene, and urban evolutionary ecology has become an important field of research. While it is commonly assumed that cities impose new and/or stronger... Continue Reading →
SEEP: Integrating society, ecology, evolution, and plasticity to advance urban evolutionary ecology
In the first SEEP workshop urban evolutionary ecologists discussed collaborations with the network of Long Term Ecological Research Stations (LTER) to integrate human socio-cultural dynamics in studies of urban ecology and evolution. The field of urban evolution has only recently begun to incorporate the social dynamics of urban communities as an important covariate shaping ecology... Continue Reading →
Social-Ecological Frameworks and What the Future May Hold
“There are ecologists in urban areas, and then there are urban ecologists” - Dr. Chris Schell This point made by my advisor (Dr. Christopher Schell) creates a clear distinction that there are urban ecologists who do not fully integrate social processes (nor the full human, e.g., perceptions, culture) in their studies. And there are urban... Continue Reading →
How Do We Begin To Center Environmental Justice in Urban Ecology Research?
How Do We Begin To Center Environmental Justice in Urban Ecology Research?How Do We Begin To Center Environmental Justice in Urban Ecology Research? Urban ecology has many definitions depending on who you ask. An urban planner or a sociologist may define urban ecology as "the study of the ways that human and ecological systems evolve...

Incorporating Human Society into Urban Ecology
Urban habitats and landscapes are considerably different from their rural and natural counterparts. Rural and natural habitats experience diluted human effects (e.g., disturbance, low pollution), while urban areas and urban wildlife endure more significant impacts from humans. When we think about the influence of cities and urbanization, we typically think of more "direct" impacts such... Continue Reading →
Los Angeles Lizards: Shifts in Morphology Associated with Urban Living
Ecomorphology describes how an animal’s physical traits (called morphology) match how it uses its habitat. It is assumed that ecomorphology results from performance-morphology relationships across different habitats. For instance, running speed (a measure of performance) could be affected by limb length (a measure of morphology), but this relationship varies based on habitat (e.g. type of... Continue Reading →
