The impact of cattle grazing regimes on tropical savanna bird assemblages

AEC44(2)

Globally, agricultural land use is implicated in the decline of avifauna. In rangelands (areas used for livestock grazing), bird community responses to grazing can be complex, species‐specific and scale dependent. A greater understanding of bird responses to grazing will lead to more meaningful management recommendations.

Risk analyses are predictive systems designed to detect the risk of invasion by non‐native species. Although eucalypts are often considered moderately invasive given the extent of cultivation on a global scale, some species are widely recognized as invasive for transforming and impacting natural areas in several countries.

Responses of invasive predators and native prey to a prescribed forest fire

Fire shapes biome distribution and community composition worldwide, and is extensively used as a management tool in flammable landscapes. There is growing concern, however, that fire could increase the vulnerability of native fauna to invasive predators.

BREAKING NEWS! Small birds indifferent to miner cull

Most Australian species have been significantly disadvantaged by the massive losses of habitat that has occurred over the last 200 years of colonisation. This includes many of our native birds. However, some native species have actually flourished in this altered landscape, increasing in abundance and influence. This includes the notorious Yellow-throated Miner.  Continue reading BREAKING NEWS! Small birds indifferent to miner cull

But it’s the top of these hills that climate change is going to hit the hardest.  Continue reading Fire. Warming. Fire. Warming…. SHRUBS!

Coroner points the finger over recent extinctions

The death of a person is usually followed up with an investigation. People generally want to know the what, when, where and how the death happened. This is particularly important when the death is untimely or suspicious. People are really keen to find out who was responsible or at fault….and of course dish out some punishment. What about when an entire species dies?  Continue reading Coroner points the finger over recent extinctions

Little snails dig on leaves, indifferent to crabs


Secondary Invasion Part 3 – First, a brief recap… Yellow crazy ants invade rainforest on Christmas Island… They kill the native red land crab… And facilitate the high abundance of a whole community of exotic land snails (read the publication or the blog). So we know the mechanism of invasion success when it comes to those land snails…? Crab deletion right? Hmm, not quite the full story.  Continue reading Little snails dig on leaves, indifferent to crabs

Dingoes run the show… right down to the shrubs


If you’re a little shrub, and you thought you didn’t need to worry about apex predators… thought the vertebrate carnivore was in your area wasn’t important to your establishment and survival… Well you need to think again.  Continue reading Dingoes run the show… right down to the shrubs
