Maria Sibylla Merian\u27s Frogs

open access: yes, 2010
Maria Sibylla Merian (German, 1647-1717) is best known for her magnificent 1705 publication, Metamorphosis insectorum surinamensium, although she published earlier works on insect metamorphosis.

Strategic Innovation for Sustainability: A Conceptual Model Linking Digitalization, Social Dynamics, and Climate Change Mitigation

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT This study addresses a significant research gap in the literature by systematically reviewing and synthesizing the interplay between social dynamics, environmental changes, and organizational innovation. Although prior research has explored these dimensions in isolation, the integrative framework remains lacking.

Dynamics of Redox Metabolism during Complete Metamorphosis of Insects: Insights from the Sunflower Caterpillar Chlosyne lacinia (Lepidoptera)

open access: yesAntioxidants
Complete insect metamorphosis requires substantial metabolic and physiological adjustments. Although oxidative stress has been implicated in metamorphosis, details on redox metabolism during larva-to-pupa and pupa-to-adult remain scarce.

Timing is everything: PTTH mediated DHR4 nucleocytoplasmic trafficking sets the tempo of Drosophila steroid production

open access: yesFrontiers in Endocrinology, 2011
During development multicellular organisms must become sexually mature to reproduce. But what underlying developmental clock times this transition? Recent data shows that in fly larvae, nuclear-cytoplasmic trafficking of DHR4, a nuclear receptor, in ...

Growth and the expression of alternative life cycles in the salamander \u3ci\u3eAmbystoma talpoideum\u3c/i\u3e (Caudata: Ambystomatidae) [PDF]

open access: yes, 2003
Complex life cycles (CLCs) contain larval and adult phases that are morphologically and ecologically distinct. Simple life cycles (SLCs) have evolved from CLCs repeatedly in a wide variety of lineages but the processes that may underlie the transition ...

The effect of food on growth and metamorphosis of paedomorphs in Triturus alpestris apuanus [PDF]

open access: yes, 2001
The effect of food level on growth and metamorphosis of paedomorphs was examined in an experimental replicated design in Triturus alpestris apuanus. Paedomorphosis concerns the retention of larval characteristics in adult individuals.

Experimental and constitutive modeling investigations on marble in Jinping Underground Laboratory

open access: yesDeep Underground Science and Engineering, EarlyView.
The objective of this study is to reveal the underlying mechanisms behind the brittle‐ductile transition of the marble through a combination of experimental research and constitutive modeling. A series of triaxial compression and triaxial cyclic loading tests are conducted.

Robinow syndrome DVL1 variants disrupt morphogenesis and appendage formation in a Drosophila disease model

open access: yesDevelopmental Dynamics, EarlyView.
Abstract Background Robinow syndrome is a rare developmental syndrome caused by variants in genes in Wnt signaling pathways. We previously showed that expression of patient variants in Dishevelled 1 (DVL1) in Drosophila and chicken models disrupts the balance of canonical and non‐canonical Wnt signaling.
