Syncrip/hnRNP Q is required for activity-induced Msp300/Nesprin-1 expression and new synapse formation. [PDF]

open access: yes, 2019
Memory and learning involve activity-driven expression of proteins and cytoskeletal reorganization at new synapses, requiring posttranscriptional regulation of localized mRNA a long distance from corresponding nuclei.

Drivers of insect herbivory resistance and tolerance to plant damage in the Brachypodium distachyon species complex

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise Insect herbivory is a major biotic factor shaping plant populations and driving the evolution of defensive traits. Polyploidy (whole‐genome duplication) often induces substantial phenotypic and genotypic changes that may affect species interactions, including herbivory.

Preimaginal mortality of Musca domestica (Diptera: Muscidae) due to Habronema muscae (Nematoda: Habronematidae)

open access: yesHelminthologia, 2017
In order to study the damage of Habronema muscae (Carter, 1861) on its intermediate host, Musca domestica Linnaeus, 1758, fly larval feeding experiments were carried out. For this, a defined number of praeimaginal stages of M.

Shaped by context: Evolutionary trajectories of desiccation tolerance in land plants

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Desiccation tolerance (DT), the ability to survive near‐complete cellular dehydration, is widespread in diaspores but rare in the vegetative tissues of land plants. The patchy and punctuated phylogenetic distribution of vegetative desiccation tolerance (VDT) suggests that the trait is both ancient and recurrent, yet the evolutionary ...

Natural spawning of four Epinephelus species in the laboratory [PDF]

open access: yes, 1996
Natural spawnings of four Epinephelus species reared in the laboratory were observed from 1987 to 1992. These species are: E. summana, E. caeruleopunctatus, E. macrospilus and E. fuscoguttatus.

Zebrafish and CRISPR—A synergistic approach to decipher and cure human diseases

open access: yesAnimal Models and Experimental Medicine, EarlyView.
Zebrafish, with high genetic homology to humans, serves as a powerful vertebrate model for disease modeling and drug discovery. Integration of CRISPR/Cas9 technology enables precise genome editing, facilitating the development of translational models for human diseases.

THE ART OF WAR: PATTERNS AND MECHANISMS UNDERLYING PREDATOR-INDUCED PLASTICITY OF AMPHIBIANS [PDF]

open access: yes, 2013
Organisms often employ phenotypic plasticity as a strategy to cope with variable environments. This is particularly true of predation threats, wherein prey induce defenses to reduce detection or capture by predators.

Mandible composition and properties in two selected praying mantises (Insecta, Mantodea)

open access: yesThe Anatomical Record, EarlyView.
Abstract Insects process their food with their cuticle‐based mouthparts. These feeding structures reflect their diversity and can, in some cases, showcase adaptations in material composition, mechanical properties, and shape to suit their specific dietary preferences.

Developmental and Transcriptomic Responses in Sea Urchin Larvae to an Urban‐Associated Pollutant

open access: yesEcology and Evolution
Urban environments provide a unique opportunity to investigate the impacts of novel stressors on organismal performance. Marine intertidal zones exist at the transition from sea to land, where they are exposed to a unique suite of stressors, including ...
