"This paper provides a remarkable surprise: the Nile crocodile is not a single species, as previously thought, but instead demonstrates two species - living side-by side - constitute what has been called the Nile croc." Said Marlys Houck, geneticist with San Diego Zoo Global's Institute of Conservation Research.
"Even more remarkably, they are not each other's closest relatives; one is more closely related to New World crocodilians. The cryptic Crocodylus suchus is a unique entity worthy of a conservation strategy separate from the Nile crocodile populations of East and southern Africa."
The study, published in the October issue of Molecular Ecology, provides important information about a species that is not only an important historical icon but also critically endangered. Recent survey efforts indicate that Crocodylus suchus is declining or extirpated throughout much of its distribution. Conservationists feel that without proper recognition of this species, current sustainable use-based management policies for the Nile crocodile may do more harm than good.
The San Diego Zoo Institute for Conservation Research is dedicated to generating, sharing and applying scientific knowledge vital to the conservation of animals, plants and habitats worldwide. The work of the Institute includes onsite research efforts at the San Diego Zoo and the San Diego Zoo Safari Park (historically referred to as Wild Animal Park), laboratory work at the Arnold and Mabel Beckman Center for Conservation Research, and international field programs involving more than 235 researchers working in 35 countries.
In addition to the Beckman Center for Conservation Research, the Institute also operates the Anne and Kenneth Griffin Reptile Conservation Center, the Frozen Zoo® and Native Seed Gene Bank, the Keauhou and Maui Hawaiian Bird Conservation Centers, Cocha Cashu Biological Research Station and the Desert Tortoise Conservation Center. The Zoo also manages the 1,800-acre San Diego Zoo Safari Park, which includes a 900-acre biodiversity reserve, and the San Diego Zoo. The important conservation and science work of these entities is supported in part by The Foundation of the Zoological Society of San Diego.

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event
On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...
Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.
Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....
Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).
When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...
Using a new cooling technique MPQ scientists succeed at observing collisions in a dense beam of cold and slow dipolar molecules.
How do chemical reactions proceed at extremely low temperatures? The answer requires the investigation of molecular samples that are cold, dense, and slow at...
Scientists from the Max Planck Institute of Quantum Optics, using high precision laser spectroscopy of atomic hydrogen, confirm the surprisingly small value of the proton radius determined from muonic hydrogen.
It was one of the breakthroughs of the year 2010: Laser spectroscopy of muonic hydrogen resulted in a value for the proton charge radius that was significantly...
