Research by scientists at the University of Liverpool suggests that being raised communally makes mice more competitive when they're older. It is well known that in many animals, including humans, early-life experiences have long-lasting effects on the development of behaviours later in life. In a new study published in Scientific Reports, researchers have investigated the effects of communal rearing on competitive and exploratory behaviours in adult male house mice.
Crickets that are exposed to human drugs that alter serotonin levels in the brain are less active and less aggressive than crickets that have had no drug exposure, according to a new study led by researchers from Linköping University. The findings have been published in Scientific Reports.
Population geneticists at Bielefeld University and the British Antarctic Survey have found that eleven seal species only narrowly escaped extinction. Their study has been published today in Nature Communications.
It takes energy to make weapons, but it may take even more energy to maintain them. Because leaf-footed bugs drop their legs, it is possible to measure how much energy they allocate to maintaining this appendage that males use to fight other males.
Demand for biofuels to fight climate change clouds the future for biodiversity, says the Executive Secretary of the Intergovernmental Platform on Biodiversity and Ecosystem Services (IPBES). The demand could cause a 10- to 30-fold expansion of green energy-related agricultural land use, adding crushing pressure on habitat for plants and animals and undermining the essential diversity of species on Earth. Anne Larigauderie made the remarks at a major UN biodiversity meeting in Egypt.
In collaboration with the National Autonomous University of Nicaragua, a research group from the UPV/EHU's Plentzia Marine Station has studied the bivalves in the mangroves on both coasts of Nicaragua in order to analyse how they are affected by the pollution brought down by the rivers. That way, it will be possible to use them as sentinels or indicators of environmental changes. The research has been published by the journal Science of the Total Environment.
In August of 2017, millions peered through protective eyewear at the solar eclipse -- the first total eclipse visible in the continental United States in nearly 40 years. During the event, researchers from the Cornell Lab of Ornithology and the University of Oxford watched radar to observe the behavior of birds and insects.
A study led by researchers of the UB quantifies the presence of textile microfibers in south European marine floors. They analysed the amount of these colored fibers, which vary between 3 to 8 mm but are extremely fine, with less than a 0.1 mm diameter, and which come mainly from washing machines. The results show the dominance of cellulosic fibers over synthetic polymers, and highlight several oceanographic processes pile and transport microfibers to marine hollows.
A new study sheds light on how toothed whales adapted their sonar abilities to occupy different environments. The study shows that as animals grew bigger, they were able to put more energy into their echolocation sounds -- but surprisingly, the sound energy increased much more than expected.
A study using animal-attached technology to measure food consumption in four very different wild vertebrates has revealed that animals using a high-risk strategy to find rarer food are particularly susceptible to becoming extinct, as they fail to gather food for their young before they starve.
