Fred Short, UNH research professor of natural resources and director of the worldwide program SeagrassNet, was among the 174 scientists who contributed to “The Impact of Conservation on the Status of the World’s Vertebrates,” released online this week in the journal Science.
“Some areas, including New Hampshire, are experiencing serious loss of seagrass distribution,” says Short, “but that is different than experiencing loss of a given species, which is what the Red List process evaluates.”
The survey focused primarily on vertebrate species, finding that 20 percent of the vertebrates reviewed are classified as “threatened” by the International Union for Conservation of Nature (IUCN) and an average of 52 species of mammals, birds and amphibians move one category closer to extinction each year. In addition, the article included three plant groups.
“Inclusion of these plant groups -- seagrasses, cycads and conifers – gives a context for what’s happening with vertebrates by looking at other organismal distribution,” says Short. “Plant species provide habitat and food for vertebrates.”
Short, who is the IUCN Red List Authority focal point for seagrasses, led a three-year assessment of the world’s seagrass species for conservation status. He notes that 14 percent of seagrass species are in threatened categories based on the Red List. “We’re polluting our oceans and coastal areas tremendously,” he says. “We are most certainly losing seagrass distribution, and at present 10 of the world’s 72 seagrass species are threatened. The trends are not encouraging.”
The Science paper, whose lead author is Michael Hoffman of the IUCN, emphasizes that its concerning findings should not obscure the impact of conservation efforts, without which species losses would have been 20 percent higher. “Nonetheless, current conservation efforts remain insufficient to offset the main drivers of biodiversity loss in these groups: agricultural expansion, logging, over-exploitation, and invasive alien species,” the authors write.
Short adds that the same drivers affecting vertebrates, along with coastal development, are also threatening seagrasses in the coastal oceans.

The University of New Hampshire, founded in 1866, is a world-class public research university with the feel of a New England liberal arts college. A land, sea, and space-grant university, UNH is the state's flagship public institution, enrolling 12,200 undergraduate and 2,200 graduate students.Photographs available to download:

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.
As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...
Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.
Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...
For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.
While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...
An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.
The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...
A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.
Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
