From economy to ecological management: Portfolio theory enlightens the performance of social-ecological systems

This guest post from David Angeler (@DGAngeler), Associate Editor for Journal of Applied Ecology on the paper “Performance of salmon fishery portfolios across western North America” by Jennifer Griffiths et al. (@JenAquatic @mark_scheuerell @SteveLindley831) Ecologists and managers are well aware of the reciprocal dependence of systems between people and nature. However, the linkages between social-ecological systems are complex and therefore difficult to measure. This limits … Continue reading From economy to ecological management: Portfolio theory enlightens the performance of social-ecological systems

Eyes in the sky see the secrets of the sea

This guest post is by Kylie L. Scales (@KylieScales) on her recent review paper “On the Front Line: frontal zones as priority at-sea conservation areas for mobile marine vertebrates.” The oceans may seem like Earth’s last remaining wilderness, but are in fact teeming with human activity as a result of intense and growing demand for marine resources. Consequently, large marine vertebrates such as seabirds, turtles, … Continue reading Eyes in the sky see the secrets of the sea

Managing native fish with environmental flows

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

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

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

Special Profile: Putting applied ecology into practice

The latest issue of Journal of Applied Ecology was published this week and, along with the usual line-up of interesting research papers, reviews, and the Editor’s Choice, the issue also includes the Special Profile: Putting applied ecology into practice. This Special Profile is the output from a Journal-sponsored symposium held at INTECOL last year: Putting applied ecology into practice: knowledge and needs for the 21st … Continue reading Special Profile: Putting applied ecology into practice

Video: Plant diversity responses to organic farming and heterogeneity

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

Do green roofs enhance urban conservation?

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?

Organic farming and habitat heterogeneity benefit functional diversity

Studies comparing biodiversity in conventional and organic farming systems are many and varied. They have studied different taxa, at different scales, in different landscapes and have done so by comparing a very wide range of different metrics. While the results of these studies have been diverse, a recent meta-analysis published in Journal of Applied Ecology by Tuck et al. “Land-use intensity and the effects of … Continue reading Organic farming and habitat heterogeneity benefit functional diversity

Disrupting herd migration boosts small carnivores

The important role of small carnivores (mesopredators) is being increasingly recognised in a variety of ecosystems, with negative impacts on biodiversity often being reported where mesopredator numbers are left unchecked. This generally occurs (and is studied) in systems where there have been changes in the numbers of big, apex predators. A new study by John-Andre Henden and colleagues from Norway published recently in Journal of … Continue reading Disrupting herd migration boosts small carnivores

Protecting freshwaters from forest harvesting

Most of us depend on paper, packaging, building materials and fuel wood. Forestry is an important industry, however, the impacts on freshwaters are immense and over the years forest managers have generally come to leave some trees alongside streams to protect freshwaters, i.e., riparian buffers. A new study by Richardson and Béraud shows that the impacts they are trying to protect against are more different … Continue reading Protecting freshwaters from forest harvesting
