Invasive Species Eradication: Prioritizing Efforts and Understanding Costs

Invasive predators can have major impacts on native prey species. Eradication, if possible, can help native species rebound, but many invasion scenarios are complex and include multiple invasive predators. How do we decide which species to target first? While such decisions can be difficult, recent theoretical work has shed light on the most effective strategies.

Humans, Livestock, and Wild Carnivores

What comes to mind when you think of human and wildlife conflict? One major source of conflict is predation of livestock by wild carnivores. Livestock management strategies can help lessen conflict by reducing predation events, but those strategies must be based on sound ecological concepts to be most effective.

Which Nature is Your Nature?

Cultural understandings of nature vary widely, but global conservation efforts often fail to consider multiple perspectives regarding nature. Researchers have suggested a framework through which to better understand cultural conceptualizations of nature through language. By incorporating this framework into their correspondences, scientists may be better equipped to communicate their findings, and policy makers will have a platform from which to promote more inclusive legislation.

Excavating Extinction Histories

Extinct organisms may seem like grim study subjects, but their bones can teach us a lot about their role in the environment and what led to their extinction. By knowing how these animals contributed to their environment, we can better understand how ecosystems have changed over time. Studying their bones can also give us insight into why the organisms went extinct so that we can help prevent similar extinctions of modern species.

Is our environment affecting our weight?

When most of us think about gaining or losing weight, we see it as a straightforward equation of calories in vs. calories burned. If it’s really that simple, though, why do so many struggle with weight-loss even while following targeted diet and exercise plans? Recently, scientists have begun to identify “obesogens” – chemicals that boost obesity risk – in our environment. Understanding the role of these chemicals in obesity (in addition to diet, activity, genetics, and other known risk factors) may help us understand why some people have an especially difficult time losing weight.

The Color of Water Policy

What’s your favorite color – blue, or green? Water policy has focused traditionally on blue water (ground or surface water released into the atmosphere by evaporation), but there’s more to the water-use equation. To understand water use and availability more broadly, researchers are now considering the value and availability of green water (that which is released back to the atmosphere by plants). In this paper, green-water use and availability is investigated at a global scale, leading the authors to advocate for inclusion of green water into water policy considerations.

Gardeners for Biodiversity: How Surveys can Help Quantify Diversity in Urban Areas

Backyard gardens can boast surprising levels of biodiversity. Quantifying the diversity of many small gardens spread out across an urban area, however, can be difficult for scientists. In this study, researchers proposed a survey in which garden-owners were asked to give basic information about their gardens. From the responses, a statistical model was designed to determine the actual number of species present.
