Stunningly patterned in gray with rusty flashes and black streaks, Flammulated Owls are rightfully a top target for many birders. But their cryptic coloration makes them challenging to find, especially during the daytime. As a result, they were once considered uncommon to rare on the landscape. However, they may be more common than birders think.

“The past 2 weeks have been very good—and very bad—for Martin Wikelski and Walter Jetz. In a key proof of principle of their space-based wildlife tracking project, they published a paper tracing the travels of 15 species, including the meanderings of an endangered saiga antelope across Central Asia and the marathon flights of cuckoos from Japan to Papua New Guinea.

A newly published study led by Yale School of the Environment researchers found that a projected urban expansion of up to 1.53 million square kilometers over the next three decades threatens the survival of more than 800 species — but also that a focus on urban planning that protects habitats can mitigate the impact.

According to Walter Jetz, an ecologist who leads Yale University’s biodiversity mapping efforts, it’s essential that policymakers make data-driven decisions about which areas to protect. Otherwise “you might gain a large percentage of area protected but you have done very little in actually safeguarding species.”

Other researchers, meanwhile, are trying to use satellite-derived information about vegetation to gain insights into the animals living there. Walter Jetz, a biodiversity scientist at Yale University, and colleagues have been developing computer models that incorporate data from the research literature about the conditions that various animal species require to thrive, such as plants used for food or nests.

Decades ago, Robert MacArthur and E.O. Wilson pioneered a theory to assess how larger conserved land areas support the survival of more species. Their original theory, developed in the 1960s, was born of research on island biogeography with the observation that larger islands contain more species, but it has since been applied more broadly to species preservation.

As the world’s nations prepare to set new goals for protecting biodiversity, Yale researchers have identified where data gaps continue to limit effective conservation decisions.

It never sat well with Moura that an estimated 85% of Earth’s species are still undescribed. So, in 2018, this newly minted Ph.D. in ecology teamed up with ecologist Walter Jetz at Yale University to come up with a way to better predict where those unknowns are.

The new approach, known as ICARUS — short for International Cooperation for Animal Research Using Space — will also be able to track animals across far larger areas than other technologies. At the same time, ICARUS has shrunk the size of the transmitters that the animals wear and made them far cheaper to boot.
