Climate change to affect fish sizes and complex food webs
(University of Tasmania) Global climate change will affect fish sizes in unpredictable ways and, consequently, impact complex food webs in our oceans, a new IMAS-led study has shown.Led by IMAS and Centre for Marine Socioecology scientist Dr Asta Audzijonyte and published in the journal Nature Ecology and Evolution, the study analysed three decades of data from 30 000 surveys of rocky and coral reefs around Australia.
New temperature sensing mechanism in plants
Cell biologists reveal the phytochrome B molecule has unexpected dynamics activated by temperature, and behaves differently depending on the temperature and type of light. As climate change warms the world, crop growth patterns and flowering times will change. A better understanding of how phytochromes regulate the seasonal rhythms of plant growth will help scientists develop crops for optimal growth under the new climate and might shed light on cancer in animals.
How might climate change affect the spread of viruses? – Medical News Today
Predicting how future climate change will influence the spread of viral infections is fraught with difficulty. This is due to the complexity of interactions between climate, nature, and human activity. But annual fluctuations in some viral infections, such as seasonal…
Deserted beaches are a boon to sea turtles during nesting season
Images of empty beaches around the globe may seem strange to us, but to nesting sea turtles, the view has never looked better. Conservation officials tasked with managing nesting sites are reporting an increase in the number of female turtles…
American robins migrating 12 days earlier than they did 25 years ago
American robins can be found year-round almost anywhere in North America, from Canada’s lower provinces and southward, but many of the birds in northern areas head south for the winter. Recently, researchers have found that these robins have been migrating…
Study identifies new temperature sensing mechanism in plants
(University of California – Riverside) Cell biologists at the UC Riverside reveal the phytochrome B molecule has unexpected dynamics activated by temperature, and behaves differently depending on the temperature and type of light. As climate change warms the world, crop growth patterns and flowering times will change. A better understanding of how phytochromes regulate the seasonal rhythms of plant growth will help scientists develop crops for optimal growth under the new climate and might shed light on cancer in animals.
When three species of human ancestor walked the Earth
Scientists share details of the most ancient fossil of Homo erectus known and discuss how these new findings are forcing us to rewrite a part of our species’ evolutionary history.
Scientists show how parasitic infection causes seizures, psychiatric illness for some
Neuroscientists describe how the common Toxoplasma gondii parasite prompts the loss of inhibitory signaling in the brain by altering the behavior of nearby cells called microglia.
Ocean creatures keep millions of viruses at bay
The rainforest has long been a cradle for virus-kind. HIV, ebola and yellow fever all started out in those lush fortresses of biodiversity. But when it comes to harboring viruses, the rainforest has nothing on the ocean. Scientists have tallied…
