American Anthropologist, EarlyView.ABSTRACT The evolutionary study of human dispersal is a key topic in biological anthropology. However, recent research has revealed inconsistencies between molecular and anatomical data across different timescales and geographic regions. Despite increased interdisciplinary dialogue, these discordances are rarely analyzed in depth or interpreted for ...

SUBSTANCES WITH JUVENILE HORMONE ACTIVITY IN CRUSTACEA AND OTHER INVERTEBRATES
The Biological Bulletin, 1958 1. A new assay for the juvenile hormone of insects is described which permits detection of very small amounts of hormone activity.2. Using this procedure extracts of a variety of invertebrates were assayed for juvenile hormone activity.3. Juvenile hormone activity was detected in Hydrozoa, Polychaeta, Oligochaeta, Lepidoptera, Coleoptera, Decapoda ...

Ibis, EarlyView.Mountain ecosystems are under strong environmental pressure and are considered highly vulnerable to climate change, which is likely to lead to forest expansion and loss of open alpine grasslands, threatening many specialized species. However, for most alpine birds, even basic ecological knowledge, such as their diet, remains limited, restricting our ...

RNA activation in insects: From emerging evidence to molecular applications
Insect Molecular Biology, EarlyView.Canonical RNA activation involves small RNAs interacting with promoter sequences, but there is also evidence of non‐canonical RNAa in eukaryotes. Emerging evidence suggests the presence of RNAa in insects. RNAa can be utilised as a tool for functional genomic studies in insects.

Journal of Fish Biology, EarlyView.Abstract Methods using environmental nucleic acids have become highly effective for monitoring aquatic biodiversity, with an array of suitable use cases, including metrics for fisheries assessment. Traditional methods for assessing fish populations often rely on invasive techniques with limited spatial and temporal coverage.

Activation of membrane guanylate cyclase by an invertebrate peptide hormone
Journal of Biological Chemistry, 1990 Peptide hormones can stimulate cyclic GMP synthesis through either of two general mechanisms: some peptides activate the cytoplasmic form of guanylate cyclase via a coupling factor called EDRF (endothelium-derived relaxation factor), while others activate the membrane form by interacting directly with an extracellular binding domain of the cyclase ...

Altered photoperiod affects behaviour in a key fish grazer, the thinlip grey mullet, Chelon ramada
Journal of Fish Biology, EarlyView.Abstract The aim of this study is to address experimentally the immediate impacts of an alteration of the photoperiod, simulating an extreme artificial light pollution, on the behaviour and stress of a key grazer fish common in temperate coastal ecosystems in Europe, the thinlip grey mullet, Chelon ramada.

Journal of Fish Diseases, Volume 48, Issue 4, April 2025.ABSTRACT The pejerrey (Odontesthes bonariensis) is a key species for recreational and commercial fisheries in Argentina and holds significant aquaculture potential. It has been introduced to various countries worldwide, including Japan, where intensive aquaculture has developed.

Desiccation tolerance mechanisms in the green lineage and beyond
New Phytologist, EarlyView.Ancient origin and recurrent evolution of desiccation tolerance in the green lineage. Summary Water is essential for life on Earth, yet some plants can survive the near‐complete loss of cellular water, a trait known as desiccation tolerance. Although rare in vegetative tissues of vascular plants, desiccation tolerance is scattered across the plant ...

A Novel AP2/ERF Transcription Factor Controls Trichome Initiation and Fruit Development in Cucumber
Plant Biotechnology Journal, EarlyView.ABSTRACT Trichomes, the hair‐like outgrowths of the plant epidermis, are critical for defence, reproduction and development. However, the underlying molecular mechanisms governing their initiation remain elusive. Here, we identified CsGL2, an AP2/ERF transcription factor, as a key integrator controlling trichome initiation and fruit development in ...
