New research by the University of Plymouth represents one of the first studies to examine the effectiveness of targeted lionfish removals from both an ecological and a socio-economic perspective.
A landmark scientific study involving marine biologists from Greece, Turkey, Cyprus, Libya, Italy, Tunisia, the UK, the US and even Malta, documenting instances where native Mediterranean species have preyed upon two highly invasive marine fish - the Pacific red lionfish and the silver-cheeked toadfish - has just been published.
Scientists from UC Davis have developed a tool that is able to differentiate the endangered salt marsh harvest mouse from its non-endangered doppelgänger with up to 99% accuracy.
Whether summer or winter, midnight sun or polar night - the sand on the ocean floor is always inhabited by the same bacteria. Although the microbial communities differ between different ocean regions, they do not change between the seasons. Presumably, there is simply no room for change. Researchers at the Max Planck Institute for Marine Microbiology in Bremen, Germany, now describe this phenomenon in a study published in the journal ISME Communications.
New findings from zoologists working with birds in Southeast Asia are shining fresh light on the connections between animal behaviour, geology, and evolution - underlining that species can diversify surprisingly quickly under certain conditions. Sulawesi Babblers (Pellorneum celebense), shy birds that live in the undergrowth on Indonesian islands, have begun to diverge quite significantly despite being separated geographically for mere tens of thousands of years.
In a recent article in the journal Agriculture, Ecosystems & Environment, a group of researchers analysed how farmland consolidation influences wild pollinator communities. They discovered that consolidation, while trying to optimise the productivity and output of the land, reduces the diversity of pollinators by 30%.
For more than a century, researchers have relied on flat sketches of sharks' digestive systems to discern how they function -- and how what they eat and excrete impacts other species in the ocean. Now, researchers have produced a series of high-resolution, 3D scans of intestines from nearly three dozen shark species that will advance the understanding of how sharks eat and digest their food.
The Xerces blue butterfly is generally accepted as the first American insect species destroyed by urban development, but there are lingering questions about whether it was really a species to begin with, or just a sub-population of another common butterfly. In a new study, researchers analyzed the DNA of a 93-year-old Xerces blue specimen in museum collections, and confirmed that it was a unique species.
A new study shows that DNA duplication has been vitally important throughout the evolutionary history of gymnosperms, a diverse group of seed plants that includes pines, cypresses, sequoias, ginkgos and cycads.
This summer, if you see a butterfly with wings that are blue on top with orange spots underneath, you may have crossed paths with a male European Common Blue (or Polyommatus icarus), a newly introduced species in Canada. Could it be a fluke? Probably not, according to a group of researchers from the University of Ottawa who have taken a close look at this captivating blue creature. They are in fact the first to study its ecology.
