“…In B. straminea, the genetic variation in both groups was similar, possibly reflecting a more recent spatial colonization potentialized by the high ability of the species to colonize new habitats (13,58). The expansion of the heat shock protein family in the genome of B. straminea (59) can improve the adaptability of the species to environmental stressors, causing B. straminea to spread to new environments across local and continental geographic scales.…”

IntroductionBiomphalaria glabrata, B. tenagophila, and B. straminea occurrence are crucial for estimating the risk of infectious human schistosomiasis in the neotropics. How different geographic sample strategies influence snail genetic diversity estimations were here investigated for three Schistosoma mansoni hosts.MethodsMitochondrial gene sequences were employed for Cytochrome C Oxidase I (COI), ribosomal RNA (rRNA) 16S, and a dataset with concatenated gene sequences (COI+16S), resulting in an improved scientific hypothesis regarding the geographical distribution of snail species. This study compared the sequences of snails from the Middle Paranapanema (MP) hydrographic basin in a geographically restricted area (inner group) to snails widely distributed across a broad geographical range in São Paulo (outer group), Brazil from 1999 to 2017. DNA sequence polymorphisms and haplotype diversity were estimated using DNAsp software. Haplotype network trees were constructed using a network program. The geographical distribution of the haplotypes was mapped using QGIS. Haplotype variation and distribution were tested for population structure using analysis of molecular variance (AMOVA).Results and discussionThe genetic diversity of B. glabrata, sampled from disconnected but geographically close freshwater collections, was partitioned into two sequence groups. The haplotype network showed that the diversity of B. straminea was more spatially partitioned than in B. tenagophila, which exhibited two population groups. The haplotype distribution pattern for B. tenagophila showed many unique and exclusive haplotypes for all three loci. AMOVA showed that genetic diversity could be high in species inhabiting small geographical areas, and a large river is not a local geographical barrier for snail migration. This study found that the survey dimensions and snail samplings influenced the genetic diversity results obtained by mitochondrial DNA molecular markers.

“…In the phylogenetic analysis, the studied virus was grouped with Pittsburgh sewage-associated virus 1, a virus that was isolated from an urban sewage sample with an undetermined host ( Cantalupo and Pipas, 2018 ). Biomphalaria virus 2 was originally identified in the microbiota of health snails Biomphalaria glabrata and B. pfeifferi , vectors of protozoa from the genus Schistosoma ( Palasio et al, 2021 ). Previous studies using RdRp indicated the phylogenetic relationship of Biomphalaria virus 2 with viruses of the family Secoviridae , the only one from the order Picornavirales that has been identified to be infecting plants to date.…”

Agroforestry systems (AFS) for cocoa production combine traditional land-use practices with local biodiversity conservation, resulting in both ecological and agricultural benefits. The cacao-cabruca AFS model is widely implemented in regions of the Brazilian Atlantic Forest. Carpotroche brasiliensis (Raddi) A. Gray (Achariaceae) is a tree found in cabruca landscapes that is often used for reforestation and biotechnological applications. Despite its importance, we still lack information about viruses circulating in C. brasiliensis, particularly considering the possibility of spillover that could affect cocoa production. In our study, we analyzed the Carpotroche brasiliensis virome from Atlantic Forest and cacao-cabruca AFS regions using metatranscriptomics from several vegetative and reproductive organs. Our results revealed a diverse virome detecting near-complete or partial coding sequences of single- and double-stranded DNA and RNA viruses classified into at least six families (Botourmiaviridae, Bromoviridae, Caulimoviridae, Genomoviridae, Mitoviridae, and Rhabdoviridae) plus unclassified elements. We described with high confidence the near-complete and the partial genomes of two tentative novel viruses: Carpotroche-associated ilarvirus and Carpotroche-associated genomovirus, respectively. Interestingly, we also described sequences likely derived from a rhabdovirus, which could represent a novel member of the genus Gammanucleorhabdovirus. We observed higher viral diversity in cacao-cabruca AFS and reproductive organs of C. brasiliensis with preferential tropism to fruits, which could directly affect production. Altogether, our results provide data to better understand the virome in this unexplored agroecological interface, such as cacao-cabruca AFS and forest ecosystem, providing information on the aspects of virus–plant interactions.

“…Elucidating how environmental variables have influenced past changes in snail occurrence can help to anticipate which areas may benefit from increased surveillance for disease emergence and facilitate more precise allocation of resources. Past efforts have mapped the current climate envelope of snail habitats at the national and regional scale as well as projected the climate envelope of the Biomphalaria under future climate conditions 13,14 . The last publication of a national model of Brazil in 2012 included climate variables and vegetation greenness to map the foundational by static distribution of Biomphalaria 13 .…”

Schistosomiasis is a debilitating neglected tropical disease caused by Schistosoma parasites. In the Americas, Brazil bears the largest burden of this disease with 2 to 6 million people currently infected. Schistosoma flukes are obligate parasites of freshwater Biomphalaria snails, thus controlling snail populations is critical to reducing schistosomiasis transmission risk. As snails are sensitive to a wide range of environmental and climatic drivers, we expect that their distribution has been, and will continue to be, significantly impacted by global environmental change. Here, we leveraged cutting edge machine learning models, remote sensing data, and a 30-year dataset on snail occurrence to map the historical and current habitat suitability of competent Biomphalaria intermediate hosts. We asked (i) What are the key features of the environment that influence the distribution of suitable snail habitat? (ii) How has snail distribution shifted with climate and urbanization throughout the last three decades? Our models show that variability in climate across time, particularly for variables related to precipitation, has likely influenced broad shifts in snail host range, whereas increase in urban areas has influenced fine scale, increases in Biomphalaria habitat suitability. Elucidating change in snail distribution through time - while accounting for non-linearities that are difficult to detect from case studies - can help to inform if and when schistosomiasis control strategies should be adapted.
