Heat, safety or solitude? Using habitat selection experiments to identify a lizard's priorities
TLDR
This study emphasizes the complexity of habitat-selection behaviour in these lizards, and clarifies the criteria used in retreat-site selection when (as is commonly the case) the animal must choose between conflicting priorities. Expand
A Brave New World for an Old World Pest: Helicoverpa armigera (Lepidoptera: Noctuidae) in Brazil
TLDR
Molecular evidence via mitochondrial DNA (mtDNA) cytochrome oxidase I and Cyt b partial gene sequences for the successful recent incursion of H. armigera into the New World is provided, showing that at least two matrilines are present in Brazil. Expand
Genomic innovations, transcriptional plasticity and gene loss underlying the evolution and divergence of two highly polyphagous and invasive Helicoverpa pest species
TLDR
The extreme polyphagy of the two heliothines is associated with extensive amplification and neofunctionalisation of genes involved in host finding and use, coupled with versatile transcriptional responses on different hosts. Expand
WHY DOES TAIL LOSS INCREASE A LIZARD'S LATER VULNERABILITY TO SNAKE PREDATORS?
TLDR
Tail loss increased a lizard's chances of being consumed first by a diurnal snake (Demansia psammophis), but not by a nocturnal species (Rhinoplocephalus nigrescens). Expand
Frequency of Alleles Conferring Resistance to the Bt Toxins Cry1Ac and Cry2Ab in Australian Populations of Helicoverpa armigera (Lepidoptera: Noctuidae)
TLDR
It is suggested that alleles conferring resistance to Cry1Ac are rare and that a relatively high baseline frequency of allele conferring Resistance to Cry2Ab existed before the introduction of Bt cotton containing this toxin. Expand
Can pregnant lizards adjust their offspring phenotypes to environmental conditions?
TLDR
The modifications in body mass, tail length and response to snake scent plausibly reduce the offspring's vulnerability to predatory snakes, and hence may constitute adaptive maternal manipulations of the neonatal phenotype. Expand
Incipient Resistance of Helicoverpa punctigera to the Cry2Ab Bt Toxin in Bollgard II® Cotton
TLDR
This report of field evolved resistance to a protein in a dual-toxin Bt-crop has precisely fulfilled the intended function of monitoring for resistance; namely, to provide an early warning of increases in frequencies that may lead to potential failures of the transgenic technology. Expand
TRADING HEAT AND FOOD FOR SAFETY: COSTS OF PREDATOR AVOIDANCE IN A LIZARD
TLDR
During the initial six months of the experiment, lizards reared in enclosures covered with scent from a natural predator became active later in the day, showed reduced mobility, and selected “safer” substrate microhabitats than did lizards raised in encl closures covered with control scent. Expand
Sedentary snakes and gullible geckos: predator–prey coevolution in nocturnal rock-dwelling reptiles
TLDR
These data support the notion that the 'ambush' predator benefits by remaining sedentary within a retreat-site for long periods, because it thereby minimizes the extent to which it spreads its scent over the rocks forming the crevice. Expand
Vip3A Resistance Alleles Exist at High Levels in Australian Targets before Release of Cotton Expressing This Toxin
TLDR
It is appropriate to pre-emptively screen key targets of Bt crops elsewhere, especially those such as H. zea in the USA, which is not only closely related to H. armigera but also will be exposed to Vip in several varieties of cotton and corn. Expand
