The free-living flatworm Macrostomum lignano [PDF]

EvoDevo, 2020
AbstractMacrostomum lignano is a free-living flatworm that is emerging as an attractive experimental animal for research on a broad range of biological questions. One feature setting it apart from other flatworms is the successful establishment of transgenesis methods, facilitated by a steady supply of eggs in the form of single-cell zygotes that can ...

Multicriteria GIS‐based analysis for the evaluation of the vulnerability of the marine environment in the Gulf of Trieste (north‐eastern Adriatic Sea) for sustainable blue economy and maritime spatial planning

People and Nature, Volume 5, Issue 6, Page 2006-2025, December 2023., 2023
Abstract The Gulf of Trieste, is a shallow semi‐enclosed sea of about 500 km2 in the north‐eastern part of the Adriatic Sea. The coastal and marine areas of the Italian region Friuli Venezia Giulia, which borders most of the Gulf of Trieste, are subject to significant pressure from human activities, especially in terms of maritime traffic, ports ...

Beached swords from Marano Lagoon (northern Adriatic) reveal ancient land–sea connections and recent coastal evolution

Archaeometry, Volume 65, Issue 2, Page 299-318, April 2023., 2023
Abstract Depositional and erosional processes, subsidence and sea‐level changes have strongly modified the coastal landscape of northern Adriatic lagoons. Such rapid transformations have induced significant consequences on human settlements and, thus, on the archaeological visibility of the area, still largely unexplored.

Sex‐specific paternal age effects on offspring quality in Drosophila melanogaster

Journal of Evolutionary Biology, Volume 36, Issue 4, Page 720-729, April 2023., 2023
We explored the effect of paternal age on offspring quality using Drosophila melanogaster. Older fathers produced heavier, higher quality offspring, particularly daughters. However, we did not detect any influence of paternal age on the ratio of offspring sexes.

Marine animal evolutionary developmental biology—Advances through technology development

Evolutionary Applications, Volume 16, Issue 2, Page 580-588, February 2023., 2023
Abstract Evolutionary developmental biology, the interdisciplinary effort of illuminating the conserved similarities and differences during animal development across all phylogenetic clades, has gained renewed interest in the past decades. As technology (immunohistochemistry, next‐generation sequencing, advanced imaging, and computational resources ...

Nutritional assessment models for diabetes and aging

Food Frontiers, Volume 3, Issue 4, Page 689-705, December 2022., 2022
Abstract Diabetes is a chronic disease, and its complexity and its various complications complicate studies in diabetes management. Aging is one of the main risk factors for diabetes, and elderly are a high‐risk group for developing the disease. In recent years, increasing evidence has revealed the underlying molecular basis for aging diabetes and its ...

Mating strategy predicts gene presence/absence patterns in a genus of simultaneously hermaphroditic flatworms

Evolution, Volume 76, Issue 12, Page 3054-3066, December 2022., 2022
Abstract Gene repertoire turnover is a characteristic of genome evolution. However, we lack well‐replicated analyses of presence/absence patterns associated with different selection contexts. Here, we study ∼100 transcriptome assemblies across Macrostomum, a genus of simultaneously hermaphroditic flatworms exhibiting multiple convergent shifts in ...

Adhesive organ regeneration in Macrostomum lignano [PDF]

BMC Developmental Biology, 2016
Abstract Background Flatworms possess pluripotent stem cells that can give rise to all cell types, which allows them to restore lost body parts after injury or amputation. This makes flatworms excellent model systems for studying regeneration. In this study, we present the adhesive organs of a marine flatworm as a simple

Evolution of sex allocation plasticity in a hermaphroditic flatworm genus

Journal of Evolutionary Biology, Volume 35, Issue 6, Page 817-830, June 2022., 2022
Interspecific variation in both sex allocation and sex allocation plasticity in the hermaphroditic flatworm genus Macrostomum, including among closely related species, suggests that both sex allocation and sex allocation plasticity are evolutionarily labile. Moreover, self‐fertilization, but not mating strategy, predicts the evolution of sex allocation

Frequent origins of traumatic insemination involve convergent shifts in sperm and genital morphology

Evolution Letters, Volume 6, Issue 1, Page 63-82, February 2022., 2022
Abstract Traumatic insemination is a mating behavior during which the (sperm) donor uses a traumatic intromittent organ to inject an ejaculate through the epidermis of the (sperm) recipient, thereby frequently circumventing the female genitalia. Traumatic insemination occurs widely across animals, but the frequency of its evolution, the intermediate ...
