在巴西的Ilha Porchat海角发现了原生的Megalobulimus paranaguensis，这是Achatina fulica通常居住的地区。这些物种的人口结构进行了研究的相互作用。进行了空间分布、生态位重叠和标记-再捕获分析。M.的外唇。paranaguensis和环境变量进行了测量。A的丰度峰分别为1个和2个。fulica和M. paranaguensis，分别。A组存活率较高。富里卡。M的分布为聚集分布。paranaguensis，而A. fulica它从随机到聚集变化。这两个物种随着丰度的增加而聚集。M. paranaguensis在这个位置的寿命比它在附近位置的寿命短。褐云玛瑙螺生长受土壤温湿度的影响; paranaguensis受湿度的影响。利基重叠是随机的。结果表明，M. paranaguensis在A. fulica，但环境退化影响了M.应该进行评估。
Native Megalobulimus paranaguensis was identified on Brazil’s Ilha Porchat promontory, an area that Achatina fulica commonly populates. The population structures of these species were investigated for interactions. Spatial distribution, niche overlap and mark–recapture analysis were conducted. The outer lip of M. paranaguensis and environmental variables were measured. One and two abundance peaks were observed for A. fulica and M. paranaguensis, respectively. Survivorship was higher in A. fulica. Distribution was aggregate for M. paranaguensis, whereas for A. fulica it varied from random to aggregate. Both species aggregate as abundance increases. The lifespan of M. paranaguensis in this location is shorter than its lifespan in a nearby location. Achatina fulica was affected by soil temperature and humidity; M. paranaguensis was influenced by humidity. Niche overlap was random. The results show that M. paranaguensis can keep its natural activity and abundance in the presence of A. fulica, but environmental degradation impacts M. paranaguensis and should be evaluated.
