Spatial ecology

Paper by Alan Pearse & Grant Hamilton published: "Giant coral reef fishes display markedly different susceptibility to night spearfishing"

Alan Pearse & Grant Hamilton have recently had a paper accepted for publication in Ecology and Evolution. This paper investigates the effect of spearfishing and habitat associations on the abundance of humphead wrasse (Cheilinus undulatus) and bumphead parrotfish (Bolbometopon muricatum). These fish are listed as Endangered and…

Discovery of new gene may lead to increased spatial range of wheat

Scientists at the University of California, Davis have recently discovered the a fourth gene in wheat responsible for wheat vernalization, the biological process requiring cold temperatures to trigger flower formation. Identification of the newly characterized VRN-D4 gene and its three previously discovered counterpart genes is crucial…

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…

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…

Genetic diversity increases in invasive population

Typically, invasive species suffer from a lack of genetic diversity compared to their source populations because populations start from a small set of founding individuals. But in a unique twist, it turns out that New Zealand’s stoat population has greater genetic diversity today than the one in Britain, posing some important questions…

Queensland agriculture continues biosecurity battle as Cucumber Green Mottle Mosaic Virus detected on north Queensland farm

A plant virus that wiped out the majority of the Northern Territory’s melon industry, has been found on a watermelon farm in north Queensland. It was initially thought the disease was contained to the Northern Territory however the recent detection of CGGMV on a north Queensland farm has important implications in regards to the spatial…
