Fate and sublethal effects of metals during amphibian metamorphosis: A systematic review

open access: yes, 2021
Amphibians provide essential ecosystem services and are facing global decline. Exposure to contaminants is a contributing factor to this decline, with permeable skin and early aquatic life likely increasing amphibian susceptibility.

Strain rate-sensitive behavior and failure mechanisms of additively manufactured 309LSi stainless steel for next-generation structures

open access: yesNext Materials
This work explores how different crosshead speeds affect the tensile properties and fracture behaviour of ER309LSi austenitic stainless steel (ASS) fabricated using Cold Metal Transfer-based Wire Arc Additive Manufacturing (CMT-WAAM).

Indoles induce metamorphosis in a broad diversity of jellyfish, but not in a crown jelly (Coronatae). [PDF]

open access: yesPLoS ONE, 2017
Many animals go through one or more metamorphoses during their lives, however, the molecular underpinnings of metamorphosis across diverse species are not well understood.

A Review on the Biology, Ecology, and Management Tactics of Helicoverpa armigera (Lepidoptera: Noctuidae)

open access: yesTurkish Journal of Agriculture: Food Science and Technology, 2022
In the agronomical field, different internal and external factors are responsible for substantially diminished crop harvest. A hindrance that can be listed in those factors is insect pests.

The identity-metamorphosis-emancipation syntagm in people with disabilities

open access: yes, 2020
Worldwide, one in seven people have disabilities. In order for them to achieve emancipation, it is essential that their identity is recognized. This was a qualitative, descriptive study based on the analysis of oral reports regarding the life trajectory ...

Neuromuscular development of Aeolidiella stephanieae Valdez, 2005 (Mollusca, Gastropoda, Nudibranchia) [PDF]

open access: yes, 2010
Background: Studies on the development of the nervous system and the musculature of invertebrates have become more sophisticated and numerous within the last decade and have proven to provide new insights into the evolutionary history of organisms.

Metamorphosis of an Enzyme

open access: yesBiotechnology & Biotechnological Equipment, 2004
The protein shells of the bifunctional Lumazine/Riboflavin synthase complex found in bacteria, archaea and plants show some similarity to the assembly of small spherical viruses. Sixty lumazine synthase subunits form a T = 1 icosahedral capsid, which instead of nucleic acids in the central core, contains a trimer of riboflavin synthase.

Les métamorphoses de l’inimitié

open access: yesAteliers d'Anthropologie, 2022
The Ashéninka report stories of meetings with peyari, a fortuitous event viewed as contact with the dead’s universe of sociability, which is liable to plunge the witness into a state of pathological stupefaction.

The role of retinoic acid signaling in starfish metamorphosis

open access: yesEvoDevo, 2018
Background Although retinoic acid (RA) signaling plays a crucial role in the body patterning of chordates, its function in non-chordate invertebrates, other than its mediation of environmental cues triggering metamorphosis in cnidarians, is largely ...

Upregulation of E93 Gene Expression Acts as the Trigger for Metamorphosis Independently of the Threshold Size in the Beetle Tribolium castaneum.

open access: yesCell Reports, 2019
Body size in holometabolous insects is determined by the size at which the juvenile larva undergoes metamorphosis to the pupal stage. To undergo larva-pupa transition, larva must reach a critical developmental checkpoint, the threshold size (TS); however,
