Little surprise saltwater crocodile swimming off local Darwin beach; I did let the surf lifeguards and swimmers know!

A BIG congratulations to Dr Tegan Dedman for completing her PhD @charlesdarwinuni.bsky.social. Effects of sea level rise on the tropical freshwater wetland communities

1500 km2 of tropical savanna dotted with crystal clear water holes. Camping off the beaten track in Litchfield National Park is pretty special

Easy to feel despondent with the state of the world these days but there are still glimmers…:)

We’re finished satellite tagging sailfish here in the Top End. Now we wait for the data and start mapping movements - more coming soon

Old animals not only provide stability to populations but they can also stabilise food webs.

Older individuals make vital contributions to moderate and long-lived species, migratory animals and this where knowledge and cultural transmission are important. We refer to these as old animal storage effects and synthesise the benefits across life history strategies

Second, research conducted on old animals usually focuses on the negative aspects of ageing but that literature is changing rapidly.

Old animals across a wide range of taxa provide important ecological functions, but these are being eroded.
