Seafloor-foraging sea snakes sometimes perform a puzzling wiggle
Researchers have for the first time closely tracked the fine-scale diving behavior of two species of sea snakes that forage along the seafloor and discovered that one species performs a curious wiggle while traveling underwater. "Most sea snakes live their entire lives in water, but, like seals and turtles, they cannot breathe underwater," says University of Adelaide Ph.D. candidate, Shannon Coppersmith, who led the study.
Seafood unfairly singled out in microplastics debate
An international team of researchers, led by Heriot-Watt University and involving the University of Adelaide, analysed how plastic contamination in food is studied and reported. They found that more than 70 per cent of scientific and media coverage on microplastics in food has focused on seafood, contributing to the public perception that eating fish is the biggest risk.
Research ties fossil fuel projects to warming, climate disasters
An emissions-impact calculation method used by the Intergovernmental Panel on Climate Change (IPCC) has been employed to assess the amount of warming a single Australian fossil fuel project will cause based on its projected CO2 emissions, and the follow-on impacts to human health and the environment.
Fishy forensics improves tracking of fish migrations
As the world’s oceans warm, tropical fish species are moving into cooler waters and exploring new habitats beyond their traditional ranges. Researchers have discovered a new way to track their migration patterns by combining environmental DNA with visual surveys. “Climate change has already caused more than 12,000 species to shift their homes across land, freshwater and the sea,” says the University of Adelaide’s Dr Chloe Hayes, who has published a study on the new approach.

When domesticated rabbits go feral, new morphologies emerge
Originally bred for meat and fur, the European rabbit has become a successful invader worldwide. When domesticated breeds return to the wild and feralize, the rabbits do not simply revert to their wild form—they experience distinct, novel anatomical changes.
Illegal shark product trade evident in Australia and New Zealand
Research from the University of Adelaide's School of Biological Sciences and Wildlife Crime Research Hub has highlighted evidence of shark products entering both Australia and Aotearoa/New Zealand, including clear patterns in flows between the two countries. According to the study, published in Pacific Conservation Biology, the products identified were carried in personal luggage and postage, likely transported for personal use, as trophies, or for resale or consumption.
World-first highly cave-adapted wasp discovered in Nullarbor Caves of Australia
A team of researchers from the University of Adelaide, in collaboration with cavers, has uncovered a large number of eyeless, cave-adapted invertebrates—including spiders, cockroaches, centipedes, and, remarkably, a wasp. The wasp is the only known example in the world to show physical adaptations for life in complete darkness. It has no functional eyes, greatly elongated legs and antennae, and extremely reduced wings—an extraordinary example of evolution in extreme environments.
Energy poverty's mental health harms are about more than money
A University of Adelaide study has found that the negative effects of energy poverty on mental health are not only related to income stress and therefore differ depending on how energy poverty is defined. Lead author Dr. Rubayyat Hashmi, from the University's Australian Center for Housing Research, compared the impacts of monetary energy poverty, measured through energy expenditure and income, and self-reported energy poverty, which is a measure of perceived energy-related hardship or well-being.
The monotreme sex gene is unlike that of all other mammals Original
Researchers from the University of Adelaide, in collaboration with the University of Melbourne, University of Queensland and Monash University, have discovered that the genetic mechanism that determines sex in monotremes is different from that in all other mammals. Monotremes, which include echidnas and platypuses, differ in many aspects of their biology from all other mammals. Most distinctly, they lay eggs into a transient pouch rather than give birth to live young.
Climate change poses severe threat to bowhead whale habitat
New research examining 11,700 years of bowhead whale persistence throughout the Arctic projects that sea ice loss due to climate change will cause their habitat to severely contract by up to 75 per cent. An international team led by researchers from the University of Adelaide and the University of Copenhagen reconstructed an 11,700-year ecological baseline for bowhead whales, which are a threatened Arctic native species.

The team also found that the few patches of suitable bowhead habitat predicted to remain in the year 2100 will exist outside their current distribution, directly impacting conservation policies. “By identifying the extent and location of bowhead whale habitat that is likely to be lost in coming decades, our projections provide vital information to guide future management efforts of this emblematic species,” said Professor Eline Lorenzen, from the University of Copenhagen’s Globe Institute.
Scientists describe 71 new Australian bee species
A team of Australian researchers has discovered 71 new native bee species belonging to the resin pot bees, or Megachile (Austrochile), which are unique to Australia and present in every state and territory except Tasmania. As their name suggests, the bee species builds resin pots to protect their brood, with solitary mother bees hanging their pots individually from twigs or as clusters on the bark of trees.
Echidna microbiome changes while moms nurse puggle, research reveals
Research from the University of Adelaide shows microbial communities in echidna pseudo-pouches undergo dramatic changes while the animal is lactating, which could help in creating an environment for their young, known as puggles, to thrive. Echidnas are monotremes, which are the only mammals that lay eggs. The early developmental stage at which they hatch from their egg means that the puggles lack a functioning immune system.
Water molecules form harmonized networks during hydrolytic reactions
Researchers from the University of Adelaide have discovered how water molecules are organized during plant hydrolytic reactions, knowledge that could have sweeping consequences for the biomedical, pharmaceutical, food and chemical industries. The research team, led by Professor Maria Hrmova from the University of Adelaide, identified enzyme components that underlie water molecule networks and function as principal operators to regulate water flux during hydrolytic reactions.

The MAPHEUS 15 sounding rocket was successfully launched at 7:38am (UTC) on Monday, 11 November, and contained 21 scientific experiments from organisations all around the world.
Politicization of water use exacerbates farmers' distrust, researchers find
Researchers have found that in agricultural areas with declining resource availability, climate-adaptation risks increase when discussion about water allocation becomes politicized. The finding was made through the examination of water management in the Langhorne Creek viticultural region, where researchers assessed the hydrosocial risk in 2021.
Politicisation of water use exacerbates farmers’ distrust
The finding was made through the examination of water management in the Langhorne Creek viticultural region, where researchers assessed the hydrosocial risk in 2021. “Hydrosocial risks arise from the social processes that influence, and are influenced by, human interactions with water,” says Associate Professor Douglas Bardsley, from the University of Adelaide’s School of Social Sciences, who produced the study in association with colleagues Associate Professor Georgina Drew and Dr Bill Skinner.
Research shows that glossy black-cockatoos prefer to feed from trees growing in acidic soils
Glossy black-cockatoos are seed-eating birds that feed almost exclusively on the cones of drooping sheoak trees. However, counter-intuitively, they select trees that grow on the poorest soils found on ancient sedimentary rocks. "Sheoak trees are three times more likely to be used as feeding trees if they are growing on non-limestone sedimentary rocks," says Dr. Gay Crowley, from the University of Adelaide's School of Social Sciences.

Research shows the ocean is becoming too loud for oysters
Baby oysters rely on natural acoustic cues to settle in specific environments, but new research from the University of Adelaide reveals that noise from human activity is interfering with this critical process. "The ocean's natural sound is gradually hushing due to habitat loss, leading to a quieter natural environment increasingly drowned out by the crescendo of man-made noise pollution," explained lead author Dr. Brittany Williams, from the University's Southern Seas Ecology Laboratories.
