Rats are part of the urban ecosystem and an urban ecology approach to managing their populations may involve learning to share the city.
An ecosystems approach to cities that recognizes rats as part of the ecosystem can help address the challenges presented by urban rats.
Caracals that feed on poisoned rodents in Cape Town pass the toxins onto their young through contaminated milk.
Household rat poison is endangering caracals, and other wildlife species in Cape Town, that prey on poisoned rodents. If not managed, this can negatively alter the region's ecosystem.
Koalas can adapt to urban areas with enough suitable green spaces but would benefit from wildlife crossing areas to reduce their risk of being hit by cars.
Koalas can cope with the stresses of city life provided we plan urban developments in ways that help meet their basic needs.

Keeping urban habitats such as parks neat and tidy by removing dead wood and leaves is driving the species which live there to extinction.
A kangaroo finds refuge in a small patch of vegetation surrounded by a new housing estate.
Expanding cities and farmland have created many small, often isolated patches of vegetation. Long seen as having limited ecological value, a new study shows these are vital for endangered species.
Brisbane’s South Bank parkland isn’t exactly getting out in the wild, but experiences of urban nature are important for building people’s connection to all living things.
Moves to connect people with nature for both the conservation and health benefits point to the need for people to experience nature as they find it in the city, rather than only out in natural areas.

Urban trees are literally made with the help of human breath – they turn the carbon dioxide we breathe out into the building blocks of plant growth. So your local trees have a piece of you inside them.

It's becoming harder and harder for animals to find human-free spaces on the planet. New research suggests that to try to avoid people, mammals are shifting activity from the day to the nighttime.
Even pocket parks in cities (Duane Park in Lower Manhattan, pictured here) can shelter wildlife. Read below for ideas about urban biodiversity and other green innovations.
Trump administration rollbacks dominated news about the environment in 2017 – but beyond Washington D.C., many researchers are developing innovative visions for a greener future.
A coyote cools off in the shade of a leafy suburb. Wildlife interactions with pets and humans can transfer disease, including the tapeworm Echinococcus multilocularis.
A parasite found in coyotes, wolves and foxes is now spreading to dogs and their owners as its range expands across Canada.
The birds commonly seen in urban backyards of Australia are increasingly introduced species like this house sparrow, sharing a birdbath with a native red-browed finch.
We all know how vital it is for our native bird species to thrive. But what if the only birds that visit your garden are introduced "pest" species? Many people feel these birds deserve some love too.
Citizen science projects are a way to contribute to science from your own backyard.
From birds to bees, the wildlife in your backyard can tell us important things about the health of our environment.
Tim Laman was the overall winner of the Wildlife Photography Competition for his series Entwined Lives.
The Wildlife Photographer of the Year exhibition features sumptuous images: from giant cuttlefish courting to a vertigo-inducing portrait of an orangutan taken with a GoPro camera.
Native plants don’t need much space really.

It is possible to use small spaces such as transport corridors, verges and the edges of sporting grounds for native wildlife habitat restoration, helping to bring biodiversity back into cities.
Greening Manhattan: bringing nature into the city is one thing, making it part of our culture and everyday lives is another.
The rise of urban greening is an opportunity to recast the relationship between people and environment. Humans and non-human species are ecologically intertwined as inhabitants of cities.

Rats foul our food, spread disease and damage property, but we know very little about them. A biologist explains how he tracks wild rats in New York City, and what he's learned about them so far.
Koala numbers are in decline through increased urbanisation, but they can find a safe passage if one’s provided.
Koala numbers in parts of Australia are in decline as they move from development of their land. But they can learn to take safer routes if they are built as part of the urban design.
Much of the ‘smart cities’ rhetoric is dominated by the economic, with little reference to the natural world and its plight.

The rhetoric of 'smart cities' is dominated by the economic, with little reference to the natural world and its plight. Truly smart and resilient cities need to be more in tune with the planet.
New research shows that street lighting changes the activity of moths, and is likely to disrupt nocturnal pollination.
Worth crowing about? Birds that can problem-solve do best in cities.
Why are our cities full of crows, ravens and rainbow lorikeets, while other species decline? The answer comes down to street smarts, adaptability, and sometimes plain bullying.
