Paleontologists have discovered fossil remains belonging to an enormous 'toothed' bird that lived for a period of about 60 million years after dinosaurs.
We found 92 threatened species reported in industrial catch records. This is shameful and unnecessary.
New regulations will allow oilsands companies to release 1.3 trillion litres of liquid waste into the Athabasca River in 2022. A new technology could clean the wastewater before it's let go.
Hurricane Harvey destroyed the fishing infrastructure of Aransas Bay and reduced fishing by 80% over the following year. This removed humans from the trophic cascade and whole food webs changed.
After the Black Summer bushfires, heavy rains extinguished many fires but turned high quality water in our rivers to sludge. This is how we better prepare for next time.
Twenty of these freshwater fish species have a 50% or greater probability of extinction within the next 20 years.
Between 1986 and 2016, Kenya lost about 21 of its seagrasses.
Fish need to cross roads too. But the tunnels built to channel rivers under roads and railways can block their migrations.
Pollutants from industrial and domestic sources in the Lagos lagoon represent a cocktail of environmental contaminants.
I've worked in threatened fish conservation and management for more than 35 years, but this species is special to me.
When the post-bushfire rains finally arrived, the situation for many fish species went from dangerous to catastrophic. A slurry of ash and mud washed into waterways, sending oxygen levels plummeting.
As climate change warms northern rivers and changes precipitation patterns, some types of cold-loving fish are failing.
Mediterranean groupers are not alone: they are home to a wide variety of parasites.
A new study shows high-fibre brown rice also contains more arsenic than white rice – so which is better for you?
Fish must be released into good quality water, with suitable habitat and lots of food. These conditions have been quite rare in Murray Darling rivers in recent years.
Colossal squid have eyes the size of soccer balls, and can weigh up to 700kg. That's a lot of calamari!
The NSW government is soon expected to grant environmental approval to Snowy 2.0. But that process should be halted.
With restaurants closed and prices dropping, fishers are finding new ways to keep their business above water.
From a scientific perspective, the results are fascinating and world-first. From a personal perspective, what I saw will stay with me for a long time.
The arrangement of bones in our specimen's fins are the same as those of 'fingers' in tetrapods. The only difference is the digits are locked within the fin, and not free moving.
