The entire population of these birds – less than 125 – lives on one tiny island in the south Pacific, and without serious intervention, they will no longer exist. One University of Missouri researcher is trying to stop the birds' extinction by working with farmers and residents on the island inhabited by the kingfishers.
"If we lose these birds, we lose 50,000 years of uniqueness and evolution," said Dylan Kesler, assistant professor in fisheries and wildlife at the University of Missouri's School of Natural Resources in the College of Agriculture, Food and Natural Resources. "Because it has lived in isolation for a very long time, it's unlike any other bird. There is no other bird like this on the planet."In new studies published in the journal The Auk (published by the American Ornithologists Union) and the Journal of Wildlife Management, Kesler and his team of researchers have uncovered important information to help ensure the birds' survival and a unique way to attach radio transmitters to the birds to track them.
Exposed ground – the birds' food consists mainly of lizards, which are easier to spot where the ground is clear of vegetation. When coconut farmers conduct intermediate burns on their land – which are hot enough to kill brush, but do not lead to widespread fires or kill the lizards – it exposes more ground and the birds can see the lizards.
Dead trees for nesting – the birds create nests by flying into dead trees and hollowing cavities. Live trees are too hard and many farmers cut down their dead coconut trees. By encouraging farmers to leave some dead trees, the birds will continue to be able to build nests.
Lessoning the impact of predators – cats and rats, which were introduced to the island by humans, now hunt the Tuamotu Kingfisher. By wrapping metal bands around the trees, the predators are less likely to get into the nests, but Kesler is still searching for other solutions that might alleviate the pressure on the birds.
In a separate study, Kesler also developed a "weak-link" radio harness for the birds to wear. In previous studies with different birds, scientists have reported unintentional harm to the birds after attaching radio transmitters. That harm included scratching the birds, making the birds act peculiarly and introducing infections. Using this new harness, Kesler was able to track the birds during the study, and the harness was shed within two months.
"Unfortunately, even with all our work to date, the population is still crashing," Kesler said. "We're seeing some turnover, but each year when we return, there are more empty territories and the population decreases. At this rate, these birds will be gone within our lifetime."

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...

The efficiency of power electronic systems is not solely dependent on electrical efficiency but also on weight, for example, in mobile systems. When the weight of relevant components and devices in airplanes, for instance, is reduced, fuel savings can be achieved and correspondingly greenhouse gas emissions decreased. New materials and components based on gallium nitride (GaN) can help to reduce weight and increase the efficiency. With these new materials, power electronic switches can be operated at higher switching frequency, resulting in higher power density and lower material costs.
Researchers at the Fraunhofer Institute for Solar Energy Systems ISE together with partners have investigated how these materials can be used to make power...
