Brett Smith for redOrbit.com - Your Universe Online A report published in the journal PLOS ONE from a pair of researchers at Griffith University in Australia has refined the species status for the New Zealand moa – a large, extinct flightless bird. "Despite more than 100 years of research being devoted to the issue, determining species status is challenging, especially where there is an absence of substantial morphological, physiological, and behavioral data," explained study author...

Our View On How Nature Is Structured Changed By DNA Barcodes
2014-01-21 14:11:58

University of Helsinki How you seek is what you find To understand how feeding interactions are structured, researchers from Finland and Canada chose to focus on one of the simplest food webs on Earth: the moths and butterflies of Northeast Greenland, as attacked by their specialist enemies, parasitic wasps and flies developing on their prey (called host), killing it in the process. "What we found in this system was mind-boggling", explains Helena Wirta, the lead author of the study....

Marine Mammal Diversity Can Be Monitored Accurately With DNA
2013-12-30 16:05:20

Lee Rannals for redOrbit.com - Your Universe Online Researchers have determined that DNA barcoding could be useful in accurately monitoring marine mammal biodiversity. Up to now, scientists have had a difficult time monitoring marine mammal biodiversity. Some species can be easily observed, while others are more difficult because of their scarcity or their discrete behavior. Researchers collaborated to determine whether or not DNA barcoding could be useful for monitoring this type of...

Developing DNA Barcode Libraries From Museum Collections
2013-12-30 13:26:26

Pensoft Publishers The ability to sequence the DNA of plants and animals has revolutionized many areas of biology, but the unstable character of DNA poses difficulties for sequencing specimens in museum collection over time. In an attempt to answer these issues, a recent study of 31 target spider species from the Naturalis Biodiversity Center in Leiden, discovers that both time and body size are significant factors in determining which specimens can produce DNA barcode sequences. The study...

DNA Barcodes Help Identify Palms
2013-12-30 13:01:17

Pensoft Publishers Reliable and cost-effective species recognition is the dream of many scientists, and has important applications. While the use of morphological features is often uncertain, and can lead to misidentification, species identification based on the composition of short DNA sequences -the so-called "DNA barcodes"- has proven to be the safest way to reach this goal, both in animals and in many groups of plants. Palms belonging to the genus Phoenix, including the...

Museum Bird DNA Is Ready To Use In Naturalis Biodiversity Center
2013-12-30 12:35:31

Pensoft Publishers DNA barcoding is used as an effective tool for both the identification of known species and the discovery of new ones. The core idea of DNA barcoding is based on the fact that just a small portion of a single gene already can show that there is less variation between the individuals of one species than between those of several species. Thus, when comparing two barcode sequences one can establish whether these belong to one single species (viz. when the amount of...

Norway Identifies 1,165 New Species Since 2009
2013-12-19 12:18:03

Norwegian University of Science and Technology More than a thousand new species –nearly one-quarter of which are new to science – have been discovered in Norway since a unique effort to find and name all of the country's species began in 2009. The Norwegian Taxonomy Initiative is one of just two government efforts worldwide where scientists are being funded to find and catalogue the country's true species diversity. The Norwegian initiative is focused on describing poorly known...

Species Such As The Cyber-Centipede Get Big Help From Big Data
2013-10-29 06:43:21

[ Watch the Video: 3D Model Of Cyber-Centipede ] April Flowers for redOrbit.com - Your Universe Online In 1735, Swedish botanist Carl Linnaeus introduced taxonomic descriptions that are designed to allow scientists to tell one species from another. A new study, published in Biodiversity Data Journal, describes a new futuristic method for describing new species that moves far beyond traditional ones. This new method combines next generation molecular methods, barcoding, and novel...

Overlooked Diversity In The Diamondback Moth
2013-08-29 11:26:57

Pensoft Publishers The tiny diamondback moth (scientific name: Plutella xylostella) gets its common name from the array of diamond shapes along the margin of its forewing. Despite their diminutive size, the caterpillars of the diamondback moth exert tremendous damage on many crops including cabbage, broccoli, and crucifers at large. More than $1 billion is spent globally each year in efforts to control damage by this moth, reflecting its amazing capacity to evolve resistance to both...
