Deafening insects mask true biodiversity assessed via acoustic surveys in Japan — ScienceDaily

A collaborative team of ecologists, led by those from Trinity College Dublin, has been using recordings of animal noises to assess biodiversity in sub-tropical Japan. The team assessed how effective these acoustic surveys were for pinpointing Okinawa’s wild and wonderful fauna in different sonic conditions — and discovered that the incessant choruses of the local cicadas disguise the true diversity of the region.

The work, just published in the journal Ecological Indicators, underlines the great potential that acoustic surveys have for characterising the biodiversity of habitats while also highlighting some major potential pitfalls.

Many scientists believe we are now living through the sixth mass extinction in Earth’s history, which has largely been driven by human actions and our exploitation of the environment, but there is general consensus that it is not too late to halt declines in biodiversity if we act now. However, we need to know which species

At least Aaron Yetter surveyed “the whole gamut of ducks,” including good numbers of mallards, on the aerial surveys during a week where the drought conditions and the unusual, even record, warmth, showed its impact on waterfowl and waterfowlers.

Aaron Yetter’s latest blog off the weekly aerial waterfowl survey for the Illinois Natural History notes “the whole gamut of ducks,” but also the impact of the drought conditions and record warmth.

November 6th, 2020 – Aerial Waterfowl Inventory Blog

We got up early this week and flew the survey on November 3rd. Duck numbers were pretty good and totaled right at or slightly above the 10-yr average. This week we had over 361,000 ducks in the Illinois River Valley, and almost 368,000 along the central Mississippi River. Several times this week as I was figuring out the species composition I thought, it’s the whole gamut of ducks. Literally, there was a

New Mexico Voter Surveys: How Different Groups Voted

The numbers on this page are preliminary estimates from A.P. VoteCast, a survey conducted for The Associated Press by NORC at the University of Chicago. These surveys were conducted online and by phone, largely in the days before the election.

The first vote choice estimates will be added shortly after all polls close.

Multi-drone system autonomously surveys penguin colonies — ScienceDaily

Stanford University researcher Mac Schwager entered the world of penguin counting through a chance meeting at his sister-in-law’s wedding in June 2016. There, he learned that Annie Schmidt, a biologist at Point Blue Conservation Science, was seeking a better way to image a large penguin colony in Antarctica. Schwager, who is an assistant professor of aeronautics and astronautics, saw an opportunity to collaborate, given his work on controlling swarms of autonomous flying robots.

That’s how, three-and-a-half years later, Schwager’s graduate student, Kunal Shah, found himself at the famous McMurdo Station, ready for the first Antarctic test flight of their new multi-drone imaging system, which coordinates the flight of multiple high-end autonomous drones — but can also work with hobby drones.

The project did not have an auspicious start. “My hands were freezing. The drone batteries were too cold to work. The drone remote control was too cold. My phone was

New ‘XR For Social Impact’ White Paper Surveys Use Cases For Immersive Technologies In Education, Healthcare, And Training

Games For Change releases social impact-driven XR landscape survey at the 2020 Unity for Humanity Summit.

Over the past decade, extended reality technologies (XR)—including augmented, mixed, and virtual reality—have graduated from the stuff of science fiction to that of mainstream reality. Games like Pokémon GO and Beat Saber have acclimated people outside of narrow insider communities to the potential of XR—in both gaming and non-gaming applications—as we push into the 2020s.

But while XR is increasingly included in conversations around possible zones of innovation, oftentimes it can be hard to understand the unique opportunities and risks associated with actually developing solutions using these technologies. This is particularly true for realms outside of games and entertainment, where value oftentimes needs to be established from the outset in order
