| Abstract |
Biomphalaria pfeifferi and Biomphalaria camerunensis are intermediate hosts of the trematode Schistosoma mansoni. Up till now, very scanty data report the life history traits of these freshwater snails. This study was therefore conducted to provide further knowledge on the mating system of these two S. mansoni intermediate hosts in Cameroon. The study was performed following a three-step experimental design as follows: (i) for each species, a sample of young snails (G1), virgin and sexually mature was constituted and divided into two groups; (ii) in the first group, individuals were maintained isolated for the evaluation of the impact of self-fertilization on life history traits while in the second group, individuals were paired for few hours for the evaluation of cross-fertilization impact; (iii) in each group, fitness parameters (fecundity of G1 snails and survival of G2 offspring) were monitored during one month. The sexual maturity (age at first egg-laying) was reached, on average, at 63.9 (sd: 3.0) and 103.7 (sd: 36.6) days for B. pfeifferi and B. camerunensis, respectively. Copulation was observed in all paired individuals in both species. In B. pfeifferi, the fecundity (number of egg capsules and eggs) of young G1 individuals and survival of G2 offspring on D0 and D8 were similar between selfing and outcrossing individuals, and a very low inbreeding depression (0.063) was observed. In B. camerunensis, the fecundity of outcrossed individuals was significantly higher than that of selfed individuals. The hatching rate was significantly higher and the incubation time significantly shorter for cross-fertilized eggs as compared with self-fertilized eggs, and a high inbreeding depression (0.71) was observed. These findings may explain the high adaptability to more diverse and inconstant habitats, as well as the better compatibility of B. pfeifferi to S. mansoni compared with B. camerunensis, and may support the sustainability of S. mansoni life cycle where this intermediate host prevails. |

Attention Score in Context
This research output has an Altmetric Attention Score of 3. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 21 January 2016.
All research outputs
#7,470,187
of 22,837,982 outputs
Outputs from Parasites & Vectors
#1,857
of 5,467 outputs
Outputs of similar age
#123,358
of 393,663 outputs
Outputs of similar age from Parasites & Vectors
#40
of 150 outputs
Altmetric has tracked 22,837,982 research outputs across all sources so far. This one is in the 44th percentile – i.e., 44% of other outputs scored the same or lower than it.
So far Altmetric has tracked 5,467 research outputs from this source. They typically receive a little more attention than average, with a mean Attention Score of 5.7. This one has gotten more attention than average, scoring higher than 62% of its peers.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 393,663 tracked outputs that were published within six weeks on either side of this one in any source. This one has gotten more attention than average, scoring higher than 56% of its contemporaries.
We're also able to compare this research output to 150 others from the same source and published within six weeks on either side of this one. This one has gotten more attention than average, scoring higher than 70% of its contemporaries.
