“…Pomacea lineata, in its turn, although less abundant, is quite resistant to desiccation. In a recent study, Glasheen et al (2017) confirmed that the survival capacity of these animals to drought conditions, due to the behavior of fully burying itself in the substrate. Regarding M. tuberculata, this species has combined high tolerance to both salinities' levels (Farani et al, 2000, Silva & Barros 2015, Bolaji et al, 2011 and temperature variations (Pointier 1993), and it also supports longer desiccation periods.…”

Freshwater mollusks from three reservoirs of Piauí, northeastern Brazil

The pronounced dry season determines the characteristics of the semiarid region of Brazil. Numerous small reservoirs are built to overcome this condition, accumulating multiple uses and causing important changes in the landscape and the local biota. Considering the limited amount of information about the malacofauna of reservoirs, mainly in the Northeast region of the country, this inventory provides a list of mollusks from three important reservoirs located in the city of São Julião, state of Piauí. The collections were carried out monthly between May/2017 and April/2018, sampling a total of 11,149 mollusks, corresponding to the species Melanoides tuberculata (Müller, 1774) (n = 9,724), Biomphalaria straminea (Dunker, 1848) (n = 1,361) and Pomacea lineata (Spix, 1827) (n = 64). The richness of mollusks from the three reservoirs was low, similar to those described in studies conducted in other regions of Northeast Brazil. There was a significant difference in the abundance of M. tuberculata and B. straminea among the studied reservoirs. These environments are not connected and are installed in urban and rural areas, presenting different ecological conditions. The relationship between the human population and the reservoirs, associated with the lack of sanitation, increases the risks of spreading waterborne diseases besides the development of environmental imbalance by the introduction of exotic species.

“…Pomacea canaliculata usually inhabits shallow, slow, or stagnant waters, including water bodies that often dry out over a year (Havel et al 2014, Hayes et al 2015. It is a species considered adapted to the conditions imposed by drought because it has an amphibious habit and estivation ability (Glasheen et al 2017). Despite its occurrence, this species is registered in only two states of the Northeast, and the environmental changes resulting from the scarcity of rainfall in this region does not limit its occurrence in the semiarid.…”

Despite the great diversity, economic and environmental importance of limnic mollusks, the group is still little investigated in the Brazilian semiarid region, especially in the state of Piauí. Thus, this work aims to gather information on the diversity of limnic mollusks in the Brazilian Northeast and the semiarid region, including new records for the state of Piauí, northeastern Brazil. For this, collections in the urban perimeter of the Itaim and Guaribas Rivers, municipalities of Itainópolis, and Picos, respectively, between October 2017 and September 2019. Besides, a literature review was conducted on studies of malacofauna in the Northeast and the Brazilian semiarid region. A total of 11 species from the classes Gastropoda and Bivalvia were collected on the rivers of Piauí, being the fi rst record of Uncancylus concentricus for the Northeast region. For lotic environments in the state of Piauí, Drepanotrema schubarti, Pomacea canaliculata, Pisidium dorbignyi and Stenophysa marmorata were registered for the fi rst time. Then, it was possible to verify that the Northeast of Brazil has 71 species registered, of which 34 occur in the semiarid. The diversity of species surveyed and the fi rst record of the occurrence of several of them for the semiarid region demonstrate the importance of expanding studies involving this group to other areas. The present study is the fi rst to gather and increase the information available on the fauna of limnic mollusks for the Northeast and Brazilian semiarid regions. The information gathered here may contribute to future research and to the species conservation and the environments they occupy, especially considering the presence of non-native and vector species.

“…Contrary to our hypothesis, the diet preference of the two snails was dominated by the algae Cladophora sp. Apple snails are capable of grazing on submersed and floating macrophytes and can produce changes in the natural vegetation of the wetlands they invade (Glasheen et al, 2017). Although macrophytes (e.g., Myriophyllum) are the preferred food for the P. maculata (Burlakova et al, 2009), they can consume other resources when macrophytes decline or are less palatable, including filamentous algae (Fang et al, 2010).…”

Responses of a native and a recent invader snail to warming and dry conditions: the case of the lower Ebro River

et al. 2019

Aquatic habitats have been highly modified by human actions that reduce their native diversity and create conditions suitable for tolerant alien species. Pomacea maculata was detected in 2009 in both the alluvial plain and the final stretch of the Ebro River. Since then, a permanent population has stabilized in the littoral area of the river where the water level fluctuates according to the river discharge. Melanopsis tricarinata is an endemic snail species highly affected by the reduction of its natural habitat. Currently, the two species do not share the same reaches in the river but the possibility exists, as the distribution of the P. maculata is constantly increasing. This study aims to analyse the diets and to assess the responses of both snails to global change. The diet of both species was analysed in the field and their responses to water warming and dryness compared under laboratory conditions. This study includes the calculation of future river water temperatures based on air temperature projections. In addition, based on water discharge management scenarios, the study estimated the increase in dry riverbed area. The diet of both snail species was similar and based on Cladophora. P. maculata better resisted high temperatures and dry conditions than M. tricarinata. The projections of water temperatures showed an increase in daily temperatures, especially in summer. The hydraulic model suggested that a relevant increase in dry riverbed areas will occur. Overall, these results provide insight into the global change factors that could favour P. maculata spread in the river and the reduction of suitable habitat for M. tricarinata and will be useful for future decisions of water discharge management.
