Decline in the number and size of populations of two Lymnaeidae living in central France over the last decade

Abstract: Field investigations in 2013–2014 on acid soils and in 2016–2017 on sedimentary soils showed that populations of two lymnaeids had decreased in number in central France since 1998. As several heat waves occurred in this region in 2018, 2019 and 2020, it was useful to check whether this decline had further increased in recent years. Surveys in 56 farms in the north-west and west of the Haute Vienne department (acid soils) and 37 farms in the south of Indre (sedimentary soils) were therefore carried out in 2020 … Show more

“…It was also observed in the number of overwintering snails in many populations [ 16 , 17 ]. In 2020–2021, this decline continued [ 18 ]. According to Vignoles et al [ 18 ], this decrease in 2020–2021 could be partly due to the occurrence of successive heatwave episodes during the summer months of 2018 to 2020.…”

“…In 2020–2021, this decline continued [ 18 ]. According to Vignoles et al [ 18 ], this decrease in 2020–2021 could be partly due to the occurrence of successive heatwave episodes during the summer months of 2018 to 2020. These results raised two questions: what was the rate of the decrease in the number and size of lymnaeid populations over the past 30 years?…”
