The transformer gene controls sexual development in Drosophila suzukii

open access: yesInsect Science, EarlyView.
The transformer gene plays a key role in the genetic pathway for sexual development in Drosophila suzukii Abstract The genetic network of sex determination in the model organism Drosophila melanogaster was investigated in great detail. Such knowledge not only advances our understanding of the evolution and regulation of sexual dimorphism in insects ...

Integrable Hierarchy of Higher Nonlinear Schrödinger Type Equations

open access: yesSymmetry, Integrability and Geometry: Methods and Applications, 2006
Addition of higher nonlinear terms to the well known integrable nonlinear Schrödinger (NLS) equations, keeping the same linear dispersion (LD) usually makes the system nonintegrable. We present a systematic method through a novel Eckhaus-Kundu hierarchy,

Molecular mechanisms of sex determination in Lepidoptera: current status and perspectives

open access: yesInsect Science, EarlyView.
The genetic basis of sex determination in Lepidoptera was discovered in 2014 in the silkworm Bombyx mori. In this model species, the W chromosome‐derived small piRNA called Fem piRNA downregulates the expression of a Z‐linked gene, Masculinizer (Masc), which leads to the default female‐specific splicing of the doublesex gene (dsxF) and thus to female ...

CRISPR/Cas9‐based white pupae mutant lines in Bactrocera spp. for sterile insect technique applications

open access: yesInsect Science, EarlyView.
Bactrocera fruit flies are significant horticultural pests that cause major economic losses. A “neoclassical approach” incorporating genome editing via CRISPR/Cas9 to develop genetic sexing strains (GSS) could render the sterile insect technique (SIT) against these pests more efficient and cost‐effective.

Resource Availability and Habitat Quality Drive Time‐Lag Effects in High‐Altitude Ungulate Distribution

open access: yesIntegrative Zoology, EarlyView.
Our analysis revealed that while climate strongly influenced species distributions, habitat change drove most observed delays in distribution responses. In terms of community ecology, dispersed communities exhibited shorter time lags than concentrated groups. Analyses of lag duration revealed a 5–6‐year distribution lag effect in high‐altitude ungulate

Faith, gender and financial investment: Providence and Presbyterianism in Scotland and abroad

open access: yesAsia‐Pacific Economic History Review, EarlyView.
Abstract Mid‐nineteenth century fictional representations of misdirected investment by widows and clergy position them as ignorant in financial matters and hence pitiable. While scholars have recognised female agency in nineteenth century commerce, insufficient attention has been paid to religious belief in financial decision‐making.

Enhanced antioxidant performance of phlorotannin compounds from brown seaweed Sargassum tenerrimum via nanoliposomal encapsulation

open access: yesFood Chemistry Advances
Seaweeds contain natural antioxidants, known as phlorotannins; however, their direct use in food is limited. Nanoliposomes (NLs) have small, uniform particle sizes (20 nm), a high entrapment efficiency (90 %), and good stability.
