Can contrasting habitats influence predatory behavior in tropical forest scorpions?

Predation strategies are often habitat-dependent; therefore, contrasting biomes, such as rainforests and seasonally dry forests, may be useful for understanding how the environment influences predatory behavior. The aim of this study was to evaluate the prey capture behavior of scorpions from contra...

Description
Summary:Predation strategies are often habitat-dependent; therefore, contrasting biomes, such as rainforests and seasonally dry forests, may be useful for understanding how the environment influences predatory behavior. The aim of this study was to evaluate the prey capture behavior of scorpions from contrasting habitats in northeastern Brazil. The scorpions’ use of the stinger and movement probability after prey capture were analyzed. We collected 120 scorpions, 60 from the Atlantic Forest and 60 from the Caatinga drylands. Our results indicate that scorpions from the Atlantic Forest tended to use their stinger more frequently than those from the Caatinga habitat. We also found that Caatinga scorpions moved approximately 40% more after prey capture than the Atlantic Forest species. Environmental pressures related to the metabolic costs of venom production and potential predation risk may partially explain the differential behavior observed in this study. Therefore, our results suggest that despite the morphological differences between species, animals from contrasting habitats may show different prey capture strategies.
