Abstract:Recently, the number of alien landscape species has dramatically increased, and this could be a serious threat, not only for native species but also in cases of outbreaks for farmers. Our objective was to examine the impact of the urban environment (positive or negative) on the diversity of native species; forecast biotic homogenization or diversification of urban fauna; and determine the extent to which each of the zones are affected by invasive species. To examine the effect of urbanization, we selected 16 areas ( across three urban zones and one zone in the protected area for comparison) for this study in 2015 in Nitra. We found that snails in open locations had significantly greater species diversity and abundance of individuals than in closed locations. Slightly degraded areas had the most abundant snail species, but areas heavily disturbed had high species diversity and incidence of individuals. It appears that heavily disturbed areas are suitable as new types of refuge for snails, e.g., for Helix lucorum (Linnaeus, 1758), which was recorded in Slovakia for the first time (numerically recorded at the railway station) in 2014.

“…Achatinadea samples were collected into two types of sites within the monomodal rainfores t area: intensive agricultural areas (Njombe and Kribi rural) versus area with less agricultural activity (Ebodje and the wild forest of Dibombari). Collection was performed at night between July to September 2020 using an adaptation of a square kilometer method [ 40 , 41 ]. Coordinates of the collection areas were also taken using a GPS Triton 200.…”

Cameroon monomodal rainforest zone has a strong agricultural activity and is therefore exposed to pesticides. Furthermore, the area possesses climatic factors that favor the growth of Achatinadea snails known as African giant snails, a delicacy for the local population. The present study aimed to evaluate pesticides contamination (less vs more exposed areas) through assessment of exposure and impact on Achatinadea snails. Achatinadea snails were collected within intensive agricultural areas (Njombe and Kribi rural) and in areas with less agricultural activity (Ebodje and Dibombari). Collection was performed at night between July and September 2020 using an adapted square kilometer method. Type, number, weight, and size of the collected snails were analyzed and compared using Welsh’s One-way Analysis of variance (ANOVA). After removing the soft part from the shell, the presence of pesticides was determined using mass spectrometry. Histological analysis of kidney and ovo-testis was performed using eosin-hematoxylin staining. Results showed that the main variety of snails collected are Archachatina marginata. In areas with less agricultural activity, snails are bigger than those from more agricultural areas heavily using pesticides. Furthermore, pesticides detection showed that glyphosate, but not metalaxyl, is present in animals coming from all the collection sites. Cypermethrin was found in all the samples except in those from Dibombari. Histology revealed that the structure of the kidney and ovo-testis of snails from more exposed areas is impaired. In conclusion, this study revealed that some pesticides are transferred to snail and impair the structure of important organs.

Land snails play a crucial role in maintaining ecosystem sustainability within their habitats. Therefore, understanding the characteristics of their communities is vital for ecological studies and the development of effective conservation strategies. In this study, we employed DNA barcoding (COI gene) to identify land snails inhabiting the Hyrcanian Forest. Furthermore, we examined the variations in their community composition along elevational gradients. Snail samples were collected from three distinct elevations in three different forest locations within the Hyrcanian area of Iran. Through our comprehensive analysis, we identified a total of 10 OTUs, which were further classified into seven families and nine genera. Remarkably, five of these genera had never been reported in the study region before. By employing statistical analyses such as ANOVA and PERMANOVA, we determined significant differences in the features of snail communities across different elevations. Interestingly, we observed a decline in OTU richness with increasing elevation; however, the maximum abundance of snails was found at higher elevations. The unique climatic conditions and spatial distribution of precipitation from lowlands to highlands, as well as from west to east, make the Hyrcanian forests an ideal case study area for understanding the dynamics of land snail communities. In summary, this study provides novel insights into the land snail communities thriving in the Hyrcanian forests. The findings from our research can contribute significantly to the development of effective conservation management strategies for forest ecosystems. By understanding the factors influencing the distribution and composition of land snail communities, we can make informed decisions to protect and preserve these valuable organisms and the balance they maintain within their habitats.
