Open AccessIntrogression of early shoot vigour in wheat modifies root systems, increases competitiveness and provides options for integrated weed management
Weeds are a major biotic stressor impacting crop production. Improving the competitiveness of wheat (Triticum aestivum L.) could provide a useful tool in integrated weed management. While wheat typically exhibits...

Open AccessField evaluation of electrophysiologically-active dung volatiles as chemical lures for trap** of dung beetles
Dung beetles are economically important beneficial insects that process dung. To locate this source, they use volatile organic compounds (VOCs). The objectives of the study were to evaluate the attractiveness ...

Metabolic profiling of benzoxazinoids in the roots and rhizosphere of commercial winter wheat genotypes
Integrated weed management in commercial wheat production is urgently needed due to increasing herbicide resistance and production costs. Benzoxazinoids (BXs), which include benzoxazinones and benzoxazolinones...

Open AccessPGRMC1 effects on metabolism, genomic mutation and CpG methylation imply crucial roles in animal biology and disease
Progesterone receptor membrane component 1 (PGRMC1) is often elevated in cancers, and exists in alternative states of phosphorylation. A motif centered on PGRMC1 Y180 was evolutionarily acquired concurrently w...

Metabolomic approaches for the identification of flavonoids associated with weed suppression in selected Hardseeded annual pasture legumes
Weed suppressive potential of annual pasture legumes has been previously described, the mechanism of interference with weeds has not been clearly elucidated. We, therefore, aimed to delineate the role of secon...

Identification of phytotoxic metabolites released from Rehmannia glutinosa suggest their importance in the formation of its replant problem
The yield and quality of medicinal tubers of Rehmannia glutinosa are seriously restricted by replanting problems. However, the origin and identification of the potential allelochemicals associated with this issue...

Plant Density and Rhizosphere Chemistry: Does Marigold Root Exudate Composition Respond to Intra- and Interspecific Competition?
The development of techniques to non-destructively monitor allelochemical dynamics in soil using polydimethylsiloxane (PDMS) microtubing (silicone tubing microextraction, or STME) provides a means to test impo...

Metabolomics and Metabolic Profiling: Investigation of Dynamic Plant-Environment Interactions at the Functional Level
Sessile plants routinely face challenges associated with environmental extremes or neighbouring competitors, and have therefore developed mechanisms that allow them to withstand constant exposure to these dive...

Open AccessErratum: Ecology and genetics affect relative invasion success of two Echium species in southern Australia
Scientific Reports 7: Article number: 42792; published online: 17 February 2017; updated: 16 March 2017 In the original version of this Article, the legend of Figure 4 was incorrect: “Figure 4: There are two s...

Open AccessEcology and genetics affect relative invasion success of two Echium species in southern Australia
Echium plantagineum and E. vulgare are congeneric exotics first introduced to Australia in the early 1800 s. There, E. plantagineum is now highly invasive, whereas E. vulgare has a limited distribution. Studies w...

Trap Function and Overview of the Trap** Process
Traps are devices that delimit the displacement of previously free-ranging entities in space through time. Examples of traps used for prey capture by organisms other than humans are spider webs, ant-lion traps...

Chapter
Intersections of Movers with Traps
Catch of randomly walking organisms by a trap can occur only after an intersection with the trap or the attractive plume from a trap. The proportion of a population of ballistic (straight-line) movers caught a...

Chapter
Competing Traps
Traps are defined as competing when the presence of one or more traps reduces the catch in a given trap below what would have been registered if the additional trap or traps were not present. Two traps compete...

Trap** to Achieve Pest Control Directly
In certain cases, mass trap** alone can reduce pest populations to tolerable levels. The time required for doing so increases with pest density. Thus, this pest management tactic may work satisfactorily at l...

Why Care About Trap** Small Organisms Moving Randomly?
Most small animals such as insects follow simple behavioral rules when foraging, including moving randomly when receiving no cues from potential resources. Nevertheless, various insects, mites, nematodes, and ...

Random Displacement in the Absence of Cues
Biological random walkers randomly select headings for new steps from a normal distribution more compressed (smaller circular standard deviation (c.s.d.)) than that of classical random walkers such as diffusin...

Experimental Method for Indirect Estimation of c.s.d. for Random Walkers via a Trap** Grid
Computer simulations demonstrated that the pattern of catch across a 5 × 5 grid of traps varies predictably with random-walker circular standard deviation (c.s.d.) when movers are released just outside a grid ...

Automated Systems for Recording, Reporting, and Analyzing Trap** Data
The substantial costs of labor to deploy and tend monitoring traps for agricultural pests provide strong impetus for the development and adoption of automated trap** systems. Early steps in this direction in...

Interpreting Catch in a Single Trap
Trap findability × efficiency × retention averaged across the set of animals populating a trap** area can be abbreviated as T fer . Then, catch per trap** area is ...
