The Giant Marine Gastropod Campanile Giganteum (Lamarck, 1804) as a High‐Resolution Archive of Seasonality in the Eocene Greenhouse World

open access: yesGeochemistry, Geophysics, Geosystems, 2020
Giant gastropods are among the largest mollusks in the fossil record, but their potential as paleoseasonality archives has received little attention.

Intra- and Interspecific Foraging and Feeding Interactions in Three Sea Stars and a Gastropod from the Deep Sea

open access: yesBiology, 2023
Competitive interactions come in a variety of forms and may be modulated by the size and number of individuals involved, and/or the resources available.

Impact of the Antidiabetic Drug Metformin and Its Transformation Product Guanylurea on the Health of the Big Ramshorn Snail (Planorbarius corneus)

open access: yesFrontiers in Environmental Science, 2019
Pharmaceuticals can enter surface waters via sewage treatment plants. In the environment, the substances and their transformation products, formed by the degradation of the parent compounds, can affect aquatic wildlife, including freshwater invertebrates.

Biomineralization of primary carbonate cements: a new biosignature in the fossil record from the Anisian of Southern Italy

open access: yesLethaia, EarlyView., 2021
Biomineralization is a generic term used to indicate biological‐mediated mineral formation. In carbonate mineralization, nucleation of crystals can be: (1) controlled directly by the organisms, like in the skeletal formation of most metazoans; (2) induced by microbial communities, by indirect precipitation mediated by their metabolic activities; or (3)

Sexual selection gradients change over time in a simultaneous hermaphrodite

open access: yeseLife, 2017
Sexual selection is generally predicted to act more strongly on males than on females. The Darwin-Bateman paradigm predicts that this should also hold for hermaphrodites.

Diversity of gastropoda in the Pepe River Parangtritis, Bantul, D.I. Yogyakarta [PDF]

open access: yesBIO Web of Conferences
Gastropods are quite abundant in nature and their role in river ecosystems is very important. The Pepe River empties in the middle of Parangtritis Beach so it will be affected by tourism developed in the area.

Concomitant downregulation of neuropeptide genes in a marine snail with consecutive sexual maturation after a nuclear disaster in Japan

open access: yesFrontiers in Endocrinology, 2023
Consecutive sexual maturation (CSM), an abnormal reproductive phenomenon of a marine snail, Reishia clavigera, has occurred since 2017 in the vicinity of the Fukushima Daiichi Nuclear Power Plant after the nuclear disaster there.

Global Warming and Mass Extinctions Associated With Large Igneous Province Volcanism

open access: yesGeophysical Monograph Series, Page 83-102., 2021

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Functional Adaptations of Hemocytes of Aplysia depilans (Gmelin, 1791) and Their Putative Role in Neuronal Regeneration

open access: yesFishes
Invertebrates show great diversity in their responses to neural damage. Numerous invertebrate phyla, including gastropods, can replace all or a portion of their nervous systems.

A new genus of river snails, Bakyietaia (Mollusca, Viviparidae), from South China and the Indochinese Peninsula

open access: yesEuropean Journal of Taxonomy
A new genus of the river snail family Viviparidae, Bakyietaia Zhang, Yen & von Rintelen gen. nov., is described based on a comprehensive study of its morphology, anatomy, mtDNA (COI), ecology and distribution.
