Refining generic limits in Hyacinthinae (Asparagaceae, Scilloideae): Conflict and concordance between morphology and phylogenomics

open access: yesJournal of Systematics and Evolution, EarlyView.
Using Angiosperms353 and plastid genome skimming approaches, the generic limits of Hyacinthinae were explored using DNA sequences to better understand their evolution. Floral morphology, a traditional generic delimiter, conflicts with the molecular groupings in many cases, but bulb morphology and cytogenetics define similar groups to DNA.

Ostensive communication in great apes: The evolution of Gricean intent

open access: yesMind &Language, EarlyView.
I discuss the evolution of ostensive behaviours (behaviours that display the communicative intent to influence others through the perception of signals and actions addressed to them). Ostensive communication evolved out of evolutionary adaptations to the challenges and opportunities created by the evolutionary scenario of the meeting of ...

Ingestion of attractive toxic sugar baits containing ivermectin before and after blood feeding affects the biology and reproduction of Aedes aegypti (Diptera: Culicidae)

open access: yesMedical and Veterinary Entomology, EarlyView.
Attractive toxic sugar bait containing ivermectin (ATSB‐IVM) ingestion markedly reduced blood feeding, survival, oviposition, egg production and larval hatching, with the strongest effects when baits were ingested before blood feeding. Timing of ingestion (48–96 h before or after blood feeding) shaped sublethal impacts across the first and second ...

Natural variation in OsMYB305 downregulating cytokinin‐mediated inhibition of leaf senescence contributes to regional adaptation in rice

open access: yesNew Phytologist, EarlyView.
Proposed regulatory model of OsMYB305 in leaf senescence. Summary Accumulating evidence has identified transcription factors (TFs) as key regulators of the onset and progression of leaf senescence. However, the regulatory role of the rice myeloblastosis (MYB) TF OsMYB305 in this process remains largely unknown.

How Does the Ultra‐Processed Food Industry Drive Consumption Through Product Design and Marketing? Mapping a Complex Commercial System According to Expert Mental Models and Evidence Review

open access: yesObesity Reviews, EarlyView.
ABSTRACT The corporations that produce and profit from ultra‐processed foods (UPFs), and the regulatory conditions under which they operate, have been major contributors to the global rise of obesity and noncommunicable diseases. The aim was to map the drivers and feedback systems of the product design and marketing domains of the UPF system and to ...

Isolation and Extraction of Artificial Sweetener (Stevia) Using Stevioside Conventionally

open access: yes
Introduction: The herb The Bertoni Stevia rebaudiana family (asteraceae or compositae) is used to extract stevioside from its leaves. It serves as a natural, minimal-calorie sweetener because of its pleasant flavour.

Protein Decoys, Alcohol, and Energy Intake: Testing a Mechanistic‐Ecological Model

open access: yesObesity Reviews, EarlyView.
ABSTRACT Ultra‐processed diets are associated with excessive energy intake, but studies examining the role of alcohol have produced conflicting results, despite the high energy density of ethanol. We constructed a mechanistic‐ecological model to explain this inconsistency and tested its predictions using population dietary data.
