Rabbits and biological control: two unexpected Christmas presents

Domesticated rabbits arrived in Australia with the first fleet and some became established as feral populations around colonial settlements as early as the 1830s. However, the situation changed dramatically…
Starlings were introduced to Australia by humans, but does that matter? Simon Evans

In defence of invasive alien species

My cat caught a starling this week. By the time I intervened, the poor bird’s leg was broken, the kitchen floor was strewn with feathers, and I had to make one of those awful decisions. Was I to leave…
Native or not? Red cabbage palms found in Palm Valley in the Northern Territory were introduced by Aboriginal people thousands of years ago. Jurriaan Persyn

What is a native and why should we care?

Honeybee decline warrants concern, but not panic

In many countries there has been concern about a decline in honeybees. You may have even heard that honeybees face dangers so dire that their imminent decline threatens world food production, with potential…
