Honest signalling in predator–prey interactions: Testing the resource allocation hypothesis

Functional Ecology, Volume 39, Issue 10, Page 2833-2848, October 2025.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Warning signals are honest if they reliably deliver information about prey unprofitability to predators. One potential mechanism that may create and maintain a positive relationship between the strength of signals and defence is the resource allocation between these ...

From WGS to gels: Development and testing of PCR primers targeting toxic Digitalis in support of food safety

Applications in Plant Sciences, Volume 13, Issue 5, September-October 2025.
Abstract Premise This study capitalized on a library of single‐nucleotide polymorphisms created via whole genome sequencing (WGS) to develop and test a PCR assay for detecting toxic Digitalis species in food products. Complex foods can be difficult to analyze, but safeguarding consumer well‐being and public health necessitates that products regulated ...

Both synergism and interaction diversity explain the mixtures of defensive monoterpenes in spruce oleoresin

Functional Ecology, Volume 39, Issue 9, Page 2539-2551, September 2025.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Chemical defences, such as the monoterpenes of conifer oleoresin, frequently occur as complex blends of many components, but the selective pressures that maintain these mixtures are not yet known.

Biosynthetic approach to combine the first steps of cardenolide formation in Saccharomyces cerevisiae

MicrobiologyOpen, 2019
A yeast expression plasmid was constructed containing a cardenolide biosynthetic module, referred to as CARD II, using the AssemblX toolkit, which enables the assembly of large DNA constructs.

Using genetic data to predict the vulnerability of a native predator to a toxic invader [PDF]

, 2016
Australia has no native toad species, and as a consequence, many Australian predators lack resistance to the toxins of the invasive cane toad Rhinella marina, and die if they ingest one of these toads.

Within‐plant variation in chemical defence of Erysimum cheiranthoides does not explain Plutella xylostella feeding preference

Plant Biology, Volume 27, Issue 5, Page 861-872, August 2025.
Novel cardenolide defences co‐vary with other defences among leaves of Erysimum cheiranthoides, but while caterpillars avoid well‐defended leaves, cardenolides alone cannot explain herbivore behaviour. Abstract Plants invest a substantial fraction of their resources into defence against herbivores, with the highest levels of defence often allocated ...

Poison, plants and Palaeolithic hunters. An analytical method to investigate the presence of plant poison on archaeological artefacts [PDF]

, 2015
In this paper we present the development of a method for the detection of toxic substances on ancient arrow points. The aim is to go back in time until the Palaeolithic period in order to determine if poisonous substances were used to enhance the hunting

Allamanda cathartica leaves do not contain cardioactive glycosides [PDF]

Arquivo Brasileiro de Medicina Veterinária e Zootecnia
Allamanda cathartica, a plant used in traditional medicine for different purposes, has been considered a cardiotoxic plant. However, the alleged cardiac glycoside was not further studied. Thus, the present study aimed to determine whether the leaves of A.
