Understanding both the genetic diversity and geographical distribution of animal genetic resources is essential for their sustainable utilization, improvement, and conservation. Land snails that have adapted to arid conditions confront imminent threats such as habitat loss stemming from urbanization, agriculture, pollution, and the ever-growing impacts of environmental and climate change. The present study was undertaken to explore the current morphological variability within the land snail’s population in Algeria. From November 2022 to June 2023, 4 quantitative body measurements (shell size and live weight) and 2 qualitative traits (shell and flesh color) were recorded on 211 adult land snails from the 4 geographic provinces that comprise
different climate zones of Algeria. The collected data were first analyzed using multiple comparisons of least-square means (LSmeans), followed by generalized linear model (GLM) procedures, to explore the relationships among the measured morphometric traits and the 4 geographic zones. Univariate analyses indicated that all quantitative linear body measurements varied significantly (P.>0.05) across the phytogeographic zones. and the covariance analysis using the sampling month to illustrate the heat stress effect show a significant difference of weight body among land snail population from 4 regions. In addition, multivariate analysis show individual from Ain temouchent province are distinguished by their small shell size and low weight. These results need to be investigated further to clarify this biodiversity among land snail and their
environmental adaptation.
