There is no pulp necrosis or calcific metamorphosis of pulp induced by orthodontic treatment: biological basis

open access: yes, 2018
To biologically explain why the orthodontic treatment does not induce pulp necrosis and calcific metamorphosis of the pulp, this paper presents explanations based on pulp physiology, microscopy and pathology, and especially the cell and tissue phenomena ...

A comparison of monitoring methods for inferring demographics of a pond‐breeding amphibian population over 14 years

open access: yesThe Journal of Wildlife Management, EarlyView.
We used 4 sampling methods to estimate or index the abundance and sex ratio of spotted salamanders (Ambystoma maculatum) over 14 years. The present study highlights the importance of considering individual heterogeneity in capture probability when estimating abundance of pond‐breeding amphibians from capture data with imperfect detection. Abstract Long‐

Diversity of Insect Sesquiterpenoid Regulation

open access: yesFrontiers in Genetics, 2020
Insects are arguably the most successful group of animals in the world in terms of both species numbers and diverse habitats. The sesquiterpenoids juvenile hormone, methyl farnesoate, and farnesoic acid are well known to regulate metamorphosis ...

Morphogenesis in Drosophila melanogaster : an in vitro analysis

open access: yes, 2007
The aim of this thesis was to investigate morphogenesis in the fruit fly Drosophila melanogaster using three in vitro tissue culture systems. Primary embryonic cultures derived from Drosophila melanogaster were used to study the effect of the moulting

Plant and insect functional traits influence herbivore performance under climate change

open access: yesOikos, EarlyView.
Climate change is expected to disrupt many trophic interactions, including those between insect herbivores and their host plants, which could have detrimental effects at the ecosystem level. However, the response of insect herbivory to climate change can vary widely across species, and an understanding of the mechanisms underlying this variation is ...

Governance and infrastructure as pillars of performance: A socio‐ecological analysis of Ethiopian botanical gardens

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
While botanical gardens are often perceived merely as recreational spaces for a weekend walk, in the Global South, they are true lifelines for nature and for the people who depend on it. Our research in Ethiopia explored what actually keeps these gardens running long‐term.

Investigating the impact of estetrol and 17α-ethinylestradiol on thyroid hormonal signaling during zebrafish (Danio rerio) metamorphosis

open access: yesEcotoxicology and Environmental Safety
The thyroid axis orchestrates key biological functions in fish, including metamorphosis. Disruption of thyroid signaling by endocrine disrupting compounds (EDCs), particularly estrogens, remains understudied during this sensitive period.

HvarAKR1B1‐mediated tolerance in Hippodamia variegata: Deciphering the metabolic adaptation and fitness costs under prolonged starvation

open access: yesPest Management Science, EarlyView.
Starvation stress significantly affected the growth and development of Hippodamia variegata. Combined transcriptome and metabolome analysis and RNA interference verification revealed that HvarAKR1B1 may be involved in the response of Hippodamia variegata to starvation stress.

Mitochondrial iron supply is required for the developmental pulse of ecdysone biosynthesis that initiates metamorphosis in Drosophila melanogaster

open access: yes, 2015
Synthesis of ecdysone, the key hormone that signals the termination of larval growth and the initiation of metamorphosis in insects, is carried out in the prothoracic gland by an array of iron-containing cytochrome P450s, encoded by the halloween genes ...

Comprehensive assessment of chemical and microbial inducers for coral larval settlement across diverse coral species

open access: yesFrontiers in Marine Science
IntroductionCoral restoration efforts increasingly focus on enhancing larval settlement and post-settlement survival. However, the species-specific efficacy of different settlement inducers remains inadequately understood, limiting optimization of ...
