In 2017, the group from the Optics of Photosynthesis Lab (OPL) developed a new method to measure a small but important signal produced by all plants, and in this case trees. This signal is a called chlorophyll fluorescence and it is an emission of radiation at the visible and near-infrared wavelengths.
Most amber inclusions are organisms that lived in the forest. It is very rare to find sea life trapped in amber. However, an international research group led by Prof. WANG Bo from the Nanjing Institute of Geology and Palaeontology of the Chinese Academy of Sciences (NIGPAS) reported the first known ammonite trapped in amber in a study in PNAS published on May 13.
GAINESVILLE, Fla. --- The human environmental footprint is not only deep but old. Ancient traces of this footprint can be found in animal bones, shells, scales and antlers at archaeological sites. Together, these specimens tell the millennia-long story of how humans have hunted, domesticated and transported animals, altered landscapes and responded to environmental changes such as shifting temperatures and sea levels.
Unraveling the secrets of the relationship between coral and the algae living inside it will help prevent coral bleaching, University of Queensland researchers believe.
Climate change has already increased the spread and severity of a fatal disease caused by Ranavirus that infects common frogs (Rana temporaria) in the UK, according to research led by ZSL's Institute of Zoology, UCL and Queen Mary University of London published today in Global Change Biology (10 May 2019).
An international team of researchers discovered a previously unknown visual system that may allow color vision in deep, dark waters where animals were presumed to be colorblind. The research appears on the cover of the May 10, 2019, issue of the journal Science.
A recently documented stand of bald cypress trees in North Carolina, including one tree at least 2,624 years old, are the oldest known living trees in eastern North America and the oldest known wetland tree species in the world.
Fish living up to 1500 meters below the surface have developed a surprisingly diverse vision that could help them determine predator from prey in the dimly-lit depths of their fish-eats-fish world.
Scientists have discovered how two closely-related species of Asiatic dayflower can coexist in the wild despite their competitive relationship. Through a combination of field surveys and artificial pollination experiments, the new study shows that while reproductive interference exists between the two species, Commelina communis, and Commelina Communis forma ciliata, both can counter the negative effects of this interference through self-fertilization.
ANN ARBOR--A new University of Michigan study provides the first evidence of transitive inference, the ability to use known relationships to infer unknown relationships, in a nonvertebrate animal: the lowly paper wasp.
A study of parasitic crustaceans attaching themselves inside the branchial cavities (the gills) of their fish hosts was recently conducted in order to reveal potentially unrecognized diversity of the genus Elthusa in South Africa. While there had only been one species known from the country, a new article published in the open-access journal ZooKeys adds another three to the list. For one of them, the research team from North-West University (South Africa): Serita van der Wal, Prof Nico Smit and Dr Kerry Hadfield, chose the name of the fictional character Xena, the warrior princess. The reason was that the females appeared particularly tough with their characteristic elongated and ovoid bodies. Additionally, the holotype (the first specimen used for the identification and description of the previously unknown species) is an egg-carrying female. Formally recognised as Elthusa xena, this new to science species is so far only known from the mouth of the Orange River, Alexander Bay, South Africa (Atlantic Ocean). It is also the only Elthusa species known to parasitise the intertidal Super klipfish (Clinus supercilious). In fact, this is the first time an Elthusa species has been recorded from any klipfish (genus Clinus). To describe the new species, the scientists loaned all South African specimens identified as or appear to belong to the genus Elthusa from both the French National Museum of Natural History (Paris) and the Iziko South African Museum (Cape Town).
UNIVERSITY PARK, Pa. -- A thousand years ago, Native Americans in South America used multiple psychotropic plants -- possibly simultaneously -- to induce hallucinations and altered consciousness, according to an international team of anthropologists.
At least a quarter of the world's approximately 8,000 known species of amphibian are recognized as threatened and at risk of extinction. But due to a lack of data on many amphibian species, only about 44 percent of amphibians have up-to-date assessments on their risk of extinction, compared to nearly 100 percent of both birds and mammals.
DURHAM, N.H.--A distinct strain of canine distemper virus, which is a widespread virus of importance to wildlife and domesticated dogs, has been identified in wild animals in New Hampshire and Vermont, according to pathologists with the New Hampshire Veterinary Diagnostic Lab at the University of New Hampshire. No virus in this distinct subgroup of canine distemper virus has yet been reported in a domesticated dog.
Cooperation within a group of people is key to many successful endeavors, including scientific ones. According to a study published in Nature Communications, cooperation among competing fishers can boost fish stocks on coral reefs.
