(Institute of Science and Technology Austria) Sanitary care in ants to fight disease is known to improve the wellbeing of the colony, yet it has been unclear how social disease defense interferes with pathogen competition inside the individual host body. In their recent study published in Ecology Letters, Sylvia Cremer and her research group at the Institute of Science and Technology Austria (IST Austria) revealed that collective care-giving has the power to bias the outcome of coinfections in fungus-exposed colony members.
(Universitat Autonoma de Barcelona) ‘Climate clubs’ offering membership for sub-national states, in addition to just countries, could speed up progress towards a globally harmonized climate change policy, which in turn offers a way to achieve stronger climate policies in all countries. This is the key finding of a new study by researchers from the Institute of Environmental Science and Technology of the Autonomous University of Barcelona (UAB), recently published in the open-access journal Environmental Research Letters.
(Smithsonian Tropical Research Institute) In eastern Panama, canid species from North and South America are occurring together for the first time. Urban and agricultural development and deforestation along the Mesoamerican Biological Corridor might be generating a new passageway for these invasive species adapted to human disturbance.
(Max Planck Institute for Evolutionary Anthropology) Territorial conflicts can turn violent in humans and chimpanzees, two extremely territorial species. An international team of researchers from the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany, has studied the effects of territoriality on female reproductive success in wild Western chimpanzees and found that high neighbor pressure at times when females typically reproduce can lead to reproductive delays with longer intervals between births. Having many males in a group, however, is of advantage and speeds up reproduction.
(University of California – Santa Cruz) Traditional explanations for why some animals are monogamous and others are promiscuous or polygamous have focused on how the distribution and defensibility of resources (such as food, nest sites, or mates) determine whether, for example, one male can attract and defend multiple females. A new model focuses instead on social interactions driven by genetically determined behaviors, and how competition among different behavioral strategies plays out, regardless of external factors such as defensible resources.
While there have been companies selling electric motorcycles since before Tesla was selling cars, Damon Motorcycles is looking to set itself apart from the competition by offering real safety systems to help reduce collisions
Mustangs have been a part of the landscape of the United States for centuries. Ever since the first horses escaped from Spanish conquistadors, feral horses have returned to their wild roots, roaming in small family bands lead by stallions, mixing…
