Fractals, metamorphoses and symmetries in quantum field theory [PDF]

open access: yesEPJ Web of Conferences, 2022
The mechanism of spontaneous breakdown of symmetry in quantum field theory is reviewed, the Goldstone theorem derived and the formation of ordered patterns is discussed.

50 years on and still very much alive: ‘Apoptosis: a basic biological phenomenon with wide-ranging implications in tissue kinetics’

open access: yesBritish Journal of Cancer, 2022
Cell death is part of the lifecycle of every multicellular organism. Nineteenth-century pathologists already recognised that organised forms of cell death must exist to explain the demise and turnover of cells during metamorphosis (of insects ...

METAMORPHOSIS AND IDENTITY CONSTRUCTION IN SALMAN RUSHDIE’S THE SATANIC VERSE [PDF]

open access: yesUniversity of Bucharest Review. Literary and Cultural Studies Series, 2022
Metamorphic spaces (temporal, geographical and mental) produce metamorphic bodies and identities. Metamorphosis arises as a dynamic principle of survival in borderline zones.

Divergent nucleic acid allocation in juvenile insects of different metamorphosis modes

open access: yesScientific Reports, 2021
Nucleic acids help clarify variation in species richness of insects having different metamorphosis modes, a biological conundrum. Here we analyse nucleic acid contents of 639 specimens of aquatic insects collected from four high mountain streams of ...

Host–Parasitoid Phenology, Distribution, and Biological Control under Climate Change

open access: yesLife, 2023
Climate change raises a serious threat to global entomofauna—the foundation of many ecosystems—by threatening species preservation and the ecosystem services they provide.

Tadpole growth rates and gut bacterial community: Dominance of developmental stages over temperature variations.

open access: yesPLoS ONE, 2023
Tadpoles present an intriguing model system for studying the regulation and selection of gut microbiota. They offer a unique perspective to enhance our understanding of host-microbiota interactions, given their capacity to alter the dynamics of the gut ...

Local adaptation with high gene flow: temperature parameters drive adaptation to altitude in the common frog (Rana temporaria) [PDF]

open access: yes, 2014
Both environmental and genetic influences can result in phenotypic variation. Quantifying the relative contributions of local adaptation and phenotypic plasticity to phenotypes is key to understanding the effect of environmental variation on populations.

Genomic Analysis of Drosophila Neuronal Remodeling: A Role for the RNA-Binding Protein Boule as a Negative Regulator of Axon Pruning [PDF]

open access: yes, 2008
Drosophila mushroom body (MB) {gamma} neurons undergo axon pruning during metamorphosis through a process of localized degeneration of specific axon branches.

Perkembangan Metamorphosis Lalat Buah (Drosophilla Melanogaster) Pada Media Biakan Alami Sebagai Referensi Pembelajaran Pada Matakuliah Perkembangan Hewan

open access: yesBiotik: Jurnal Ilmiah Biologi Teknologi dan Kependidikan, 2015
Metamofosis adalah keseluruhan rangkaian perubahan bentuk dan ukuran sejak telur sampai menjadi dewasa (imago). Perkembangan metamorphosis sangat dipengaruhi oleh berbagai faktor.

Comparisons of genetic constraints across life stages and across temperatures from Genetic independence between traits separated by metamorphosis is widespread but varies with biological function

open access: yes, 2023
Why is metamorphosis so pervasive? Does it facilitate the independent (micro)evolution of quantitative traits in distinct life-stages, like it enables some limbs and organs to develop at specific life-stages? We tested this hypothesis by measuring the expression of 6400 genes in 41 Drosophila melanogaster inbred lines at larval and adult stages.
