This week in GigaScience we published a new genomic analysis of the endangered Oriental Stork, bringing good news: The population’s genetic health is still surprisingly strong, with high genetic diversity and low levels of inbreeding. Climate change, forest wildfires, hunting and the expansion of agriculture, industry and other human activities threaten the Oriental Stork ( Ciconia boyciana ), which is listed as
Morpho butterflies are emblematic species of the Amazonian rainforest known for their metallic shades of blue and green. Despite their conspicuous looks and fascinating biology, large-scale genome sequencing efforts have somewhat neglected them – until now.
Researchers have completed and released a chromosome-scale genome sequence of the Aldabra giant tortoise providing a much needed genetic resource for rescue efforts . The Aldabra giant tortoise is one of only two giant tortoise species left in the world, and it is currently on the threatened list. Conservation efforts are underway, but more and better tools to improve the chance of long-term success are greatly needed.
The SAMtools suite of tools for manipulating sequencing data one of the most ubiquitous tools in bioinformatics, as the “glue” holding together much of bioinformatics we see it used in pretty much every genomics pipeline we are submitted.
With the recent launch of our new GigaByte journal you may have noticed some interesting genome datasets being published, including the banjo frog, common dragonet fish, and extremely rare Nyssa yunnanensis tree. Joining these species on the genomics tree of life this month is a small mouse-like marsupial called the brown antechinus.
Bats are mammals like no other – airborne, mostly nocturnal, often hidden away in caves, capable of using echolocation for in-flight navigation. No two bat species are alike, however. Their diversity of morphology, life styles and feeding habits is staggering. New bat genomics research published today in GigaScience explores
**Today, GigaScience published a report on the genome of a truly unique species: the giant squid Architeuthis dux . The elusive animal is the main character in ancient stories about sea monsters and it is known as “the kraken” in many legends. For a long time its mere existence was questionable, until, in 1857, the Danish naturalist Japetus Steenstrup made the link between those legends and the enormous cephalopod.
New genomic data from five birds-of-paradise reveal genes that are shaped by selection and help explain the origin of their spectacular plumage. Birds-of-paradise, with their elaborate and colorful feathers and their complex courtship displays, are a school-book example of sexual selection.
In GigaScience , Benjamin Makepiece and his co-authors from Liverpool present genome assemblies of two trombidid mite species, the itch-inducing chigger mite and its more benign cousin, the velvet mite. The bite of the chigger mite can transmit a life-threatening bacterial disease, scrub typhus.
Photo: UNSW Sydney The cane toad Rhinella marina is native to Central and South America. But thanks to humans and the sugar cane trade, the species now thrives also in Australia and other places where it doesn’t belong. The invasive species comes with an unpleasant surprise for native Australian predators, such as snakes or freshwater crocodiles: R. marina kills them with its toxic secretions.
