Institute of Organic Chemistry with Center for Phytochemistry, Bulgarian Academy of Sciences, 1113 Sofia, Bulgaria.
Many biologically active compounds have been identified in the mucus of the garden snail , which are effective in the treatment of several diseases such as cancer, ulcers, wounds, etc. The incorporation of these compounds into the green synthesis of copper nanoparticles (CuONPs-Muc) was demonstrated in our previous study. Based on the synergistic effect of two reducing agents- snail mucus and ascorbic acid (AsA)-on CuSO.

Objective: To predict the potential geographic distribution of in Yunnan Province using random forest (RF) and maximum entropy (MaxEnt) models, so as to provide insights into surveillance and control in Yunnan Province.
Methods: The snail survey data in Yunnan Province from 2015 to 2016 were collected and converted into snail distribution site data. Data of 22 environmental variables in Yunnan Province were collected, including twelve climate variables (annual potential evapotranspiration, annual mean ground surface temperature, annual precipitation, annual mean air pressure, annual mean relative humidity, annual sunshine duration, annual mean air temperature, annual mean wind speed, ≥ 0 ℃ annual accumulated temperature, ≥ 10 ℃ annual accumulated temperature, aridity and index of moisture), eight geographical variables (normalized difference vegetation index, landform type, land use type, altitude, soil type, soil textureclay content, soil texture-sand content and soil texture-silt content) and two population and economic variables (gross domestic product and population).
High genomic connectivity within Anatoma at hydrothermal vents along the Central and Southeast Indian Ridge.
Sci Rep
January 2025
INES Integrated Environmental Solutions UG, Wilhelmshaven, Germany.
Hydrothermal vents are ecosystems inhabited by a highly specialized fauna. To date, more than 30 gastropod species have been recorded from vent fields along the Central and Southeast Indian Ridge and all of them are assumed to be vent-endemic. During the INDEX project, 701 representatives of the genus Anatoma (Mollusca: Vetigastropoda) were sampled from six abyssal hydrothermal vent fields.

- Norfolk Island is home to a unique land snail population, with 11 species classified as endangered or extinct due to habitat loss and predators.
- Since 2020, targeted surveys have reassessed the threat status of these snails, tracking species' distributions and implementing conservation strategies like predator control and breeding programs.
- Though initial breeding efforts showed high mortality rates, improvements in care resulted in sustainable growth rates, highlighting the need for better predator management and further refinement of conservation methods.
Reversing a reported case of transoceanic dispersal: Nudibranch identifications among tsunami debris.

In the aftermath of the 2011 east Japanese earthquake and tsunami, anthropogenic debris from the east coast of Japan floated across the Pacific Ocean to the west coast of North America. One such vessel from Iwate Prefecture arrived on the coast of Oregon, and the fouling community included specimens identified as the nudibranch Hermissenda crassicornis, which was previously thought to range from Japan to Baja California but has since been split into three species: H. crassicornis (northeastern Pacific), H.
