Flow alteration is one of the most common threats to rivers and streams around the world. Alterations such as weirs, dams and water withdrawal for human uses tend to suppress natural flow variation causing a disconnection between rivers and floodplain wetlands. These changes to the natural hydrology of rivers can have detrimental effects for fish communities because many species of fish rely on periodic access to … Continue reading Managing native fish with environmental flows
Species interactions are the foundations of ecological science. As early as pre-school, we begin building food webs and discussing the basic principles of species survival and interactions between living and non-living parts of an ecosystem. We know herbivores eat plants and prefer ‘tasty’ ones; plants compete for light, nutrients, water and space; and historical land management impacts on future actions. What we still don’t know … Continue reading When it comes to reforestation, impacts on seedling growth from competition, herbivory and land-use legacy may be as predictable as a game of Rock-Paper-Scissors
Here’s a fantastic video from Romina Rader about her recently published paper “Organic farming and heterogeneous landscapes positively affect different measures of plant diversity“. Enjoy! You can also read more about the paper in this blog post from Journal Associate Editor Ailsa McKenzie. Continue reading Video: Plant diversity responses to organic farming and heterogeneity
The environmental benefits of green roofs in urban landscapes are clear, but do they benefit biodiversity conservation? This article was written by Marc Cadotte and originally posted on The EEB and Flow blog. Green roofs are now commonly included in the design of new public and private infrastructure, bolstered by energy savings, environmental recognition and certification, bylaw compliance, and in some cases tax or other … Continue reading Do green roofs enhance urban conservation?
