Fish warn each other about danger by releasing chemicals into the water as a signal, research by the University of Saskatchewan (USask) has found. The USask researchers discovered that wild fish release chemicals called 'disturbance cues' to signal to other fish about nearby dangers, such as predators.
Galapagos giant tortoises, sometimes called Gardeners of the Galapagos, are creatures of habit. In the cool dry season, the highlands of the volcano slopes are engulfed in cloud which allows the vegetation to grow despite the lack of rain. On the lower slopes, however, there is no thick fog layer, and vegetation is not available year round. Adult tortoises thus spend the dry season in the higher regions, and trek back to the lower, relatively warmer zones where there is abundant, nutritious vegetation when the rainy season begins.
Fungi are the most common cause of diseases in crops and other plants and pose major threats to humans and other animals. The successful treatment of fungal diseases is difficult partly because the mechanisms for fungal pathogenesis remain largely unknown as well as that fungi are eukaryotes as the host cells. Multiple lifestyles have been recruited by fungi to live in different environments.
ST. PETERSBURG, Fla. (April 18, 2019)- The harmful algae that causes red tide is currently at near undetectable levels in Florida waters compared with the much higher concentrations at this time last year. The red tide algae, Karenia brevis, causes respiratory issues, is responsible for massive fish kills and is often blamed for damaging tourism.
An international team of researchers presents the first observations of the development of the skull and brain in the living coelacanth Latimeria chalumnae. Their study, published in Nature, provides new insights into the biology of this iconic animal and the evolution of the vertebrate skull.
Publishing in the journal Science, scientists propose a bold new target that would stave off biodiversity loss
If you've ever tended a garden or potted a plant, you know a few simple truths about green things -- they require water and nutrients to survive and their roots are good indicators of their overall health. So we water on a regular schedule, provide for root growth and add nutrient-rich soils to ensure a balanced diet.
In coral reef ecosystems, amid stony corals, fronds of algae and schools of fish, microorganisms are essential for recycling nutrients--transforming bits of organic matter into forms of nitrogen and phosphorus, for example, that are useful to photosynthetic organisms.
Researchers at University of Bonn develop a camera modeled on the African elephantnose fish
When species are introduced by humans into marine habitats, they can disrupt their new environment, according to a study at KAUST, which also identified key species for conservation efforts to focus on.
Shark and ray species commonly caught in the Mediterranean and Black seas are not being reported in official statistics, new research from the Sea Around Us initiative at the University of British Columbia shows.
New research by a global team of scientists has resulted in significant strides in ornithological classification and identified possible causes of diversity among modern bird species.
Svalbard reindeer adapt to dramatic climate change in a way that may foreshadow the future for other arctic species
A project conducted by researchers in Brazil and the US investigated bacteria living in symbiosis with insects as a source for novel drugs.
Deep in the ocean or underground, where there is no oxygen, Geobacter bacteria "breathe" by projecting tiny protein filaments called "nanowires" into the soil, to dispose of excess electrons resulting from the conversion of nutrients to energy.
