Distribution and dispersal of invasive species redefining biogeography in Anthropocene

  In a recent study, data on native and invasive ranges of terrestrial gastropod species was used to analyse dissimilarities in species composition among 56 globally distributed regions. it was found that native ranges confirm the traditional biogeographic realms, reflecting natural dispersal limitations. however the distribution of…

Novel methods reveal Asian origins of invasive European species

Scientists from the French National Institute for Agricultural Research (INRA) have teamed up with colleagues from the Academy of Sciences in Beijing and the Zhejiang Agriculture and Forestry University to study the ability of Chinese insect and fungal pathogens to colonise European trees. Most recent invasive species found in European…

Myrtle Rust detected in Tasmania

Earlier this year, Myrtle Rust caused by the fungal species Puccinia psidii s.l., was detected in Tasmania, Australia. Myrtle Rust is currently being studied in south east Queensland by Hamilton Ecology Lab’s very own Nadine Nolan and this could have important implications for her work. More here

The power and limitations of weather models

Here at the Hamilton Ecology Lab, we often attempt to represent a real-world system with a model. This could be the effect of weather on organisms, the spread of an invasive plant pathogen or the cyclic nature of predator-prey relationships. Whilst models can help to represent different systems in the environment, it is important to…

Genetic study reveals origin and spread of invasive Walnut twig beetle.

Researchers from the Pacific South-west Research Station (PSW) and partners from the University of California, Riverside and U.S. Forest Service Forest Health Protection have characterised the beetle’s geographic distribution and range expansion through a genetic study across vast spatial areas. An evaluation of population genetics can…
