On the Brink
Some time ago ‘On the Brink’ looked at the various native bee species. In this edition it is the European honey bee (Apis mellifera) and its impact upon the environment that is being looked at. The European honey bee was introduced into Australia in 1822. While it was brought to

In the last Brink we looked at two native species that are easily mistaken for the house mouse and the black rat (both introduced). In this edition we continue looking at more rat and mouse look-alikes. Alpine and sub-alpine huts attract bushwalkers; they are always sited near water and have

Many years ago, I was visiting a friend who lived in the Environmental Living Zone near Kangaroo Ground. I went into the kitchen and disturbed a large mouse on the counter which promptly scurried off. I called out to my friend that she had a mouse in her kitchen. She

Loss of habitat is a major driver in the decline of our wildlife populations. Most people only think of habitat in terms of the broader landscape that supports the larger, more visible species of the ecosystem. In truth, habitat and species extend down to include the microscopic level. Habitats must

Islands are like an evolutionary petri dishes. Strange things happen to the resident species. Large species morph into small species and small species morph into large species in a process known as Foster’s rule. Some of the results are surprising. On an island where there are no large predators

Trail cameras are marvellous things. They can be set to keep watch on a site 24/7. No need to rely on stumbling across wildlife. No need for live trapping or netting. Trail cameras are revealing rare, ‘extinct’ and unrecorded species and their ranges. Recent trail camera footage has revealed

With poor spring rains, not much rain over summer and then the autumn rains failing it has been an increasingly tough time for the plants and animals of our forest. Much of this has gone unnoticed; only noticed when it becomes blatantly obvious. Most days I go for a walk

Most readers will be familiar with the extinction of the thylacine, or Tasmanian tiger (Thylacinus cynocephalus). Its range once extended over Papua and New Guinea, mainland Australia and Tasmania where it was an apex predator. It became extinct in PNG and mainland Australia around 3,500 years ago; probably due

This morning, I was sitting having my morning cuppa on the veranda when a butcher bird landed in a nearby tree. I knew there were butcher birds about -I had been hearing their powerful calls and the small wrens and silvereyes that frequent my garden had made themselves scarce. I

Dire wolves were not a fictional species of wolf created for Game of Thrones. Dire wolves (Aencyon dirus) actually existed in the Americas and went extinct as recently as 10,000 years ago. Their remains show they were bigger and lighter in colour than the modern-day grey wolf (Canis lupis)
