Evolution in an Urbanizing World
In Port Phillip City, this arboreal individual has found an urban alternative to climb! https://twitter.com/SeabirdResearch/status/1666378562184826881?s=20 The Common Ringtail Possum (Pseudocheirus peregrinus) is a marsupial species, widely distributed across its native continent of Australia. This animal is arboreal and traditionally could be found in forests and woodlands primarily on the eastern coast of Australia. Currently, ringtail... Continue Reading →
The growing field of urban evolutionary ecology studies the impact of urbanization on its resident species. Often, that involves comparisons between conspecific urban and non-urban populations. Jackson et al. took a different perspective in this study. They analyzed the divergence between populations living in adjacent but isolated city parks. They developed their study around a...

Check out these dueling kangaroos in a park in Australia's Gold Coast region! New Yorkers are used to seeing squirrels and rats roam around, but Australian residents sometimes encounter much larger mammal species in their cities. There are four species of kangaroos that occupy different ranges across the Australian continent. The Red Kangaroo, Macropus rufus, is... Continue Reading →
Australia is well known for its wild animals, they are so different than what we non-Aussies are used to seeing. This week, we found an echidna in a garden! These egg-laying mammals are found everywhere in Australia, so it seems like it was a matter of time to see on in a backyard. Do you... Continue Reading →
James Baxter-Gilbert and colleagues from down under — Julia Riley and Martin Whiting — have been digging into the ecological and evolutionary responses to urbanization in a charismatic and common (at least if you're in Australia) group of lizards: Australian water dragons (Intellagama lesueurii). Previously, we told you about their findings that urban dragons are innately bold. In... Continue Reading →
Wildfires have been devastating southeastern Australia, and along with these fires comes an increase in anthropogenic noise as firetrucks race to the scene. Gregory Andrews spotted this Australian Magpie in Newcastle, New South Whales mimicking the sound of a fire truck. https://twitter.com/isobelroe/status/1212500562102505472?s=20 Do you have a photo or video of an urban species doing something...

City life can be difficult for many organisms. Cities are louder, brighter, hotter, and often more contaminated with toxins than nearby less-developed areas. Ever-increasing research is showing that organisms are coping with the urban environment in many ways. Urban great tits (Parus major) living in areas with high amounts of noise pollution sing at a...

Did you know that kangaroos are really common in parts of Australia? Here's a mob of kangaroos passing through a neighborhood! Do you have a photo or video of an urban species doing something unusual? What about a rare plant or animal that you were surprised to find in a city? If so, let... Continue Reading →
Urbanization is a global form of habitat change that alters native habits and either excludes the animals that live there or forces them to acclimate to novel environments. Altering behavioral strategies can allow individuals to quickly acclimate and successfully colonize urban habitats, reproduce and live within them. In two studies presented at SICB, researchers, Dr.... Continue Reading →
