The effect of sugarcane vinasse on the dormant forms of aquatic invertebrates

Abstract: Aim To evaluate the impacts of vinasse on the hatching of dormant forms of aquatic invertebrates, through ex-situ experimental units. Methods Sediment samples were collected from three ponds in Parque Estadual Morro do Diabo, located in Teodoro Sampaio (SP), Brazil. Each experimental unit consisted of 100 g o...

The insecticide fipronil selectively reduces the net emergence of aquatic microinvertebrates from neotropical lake sediment egg banks.

Freshwater environments rely on the sediment dormant invertebrate stages for recolonization and the maintenance of biodiversity after environmental stressors. However, while these resting structures are resilient to natural physical extremes, the effects of anthropogenic contaminants on them remain poorly understood. S...

Dormant cysts are resistant to acute malathion toxicity, but hatching phenology is altered in Dendrocephalus brasiliensis (Crustacea: Anostraca)

Dendrocephalus brasiliensis Pesta, 1921 is an anostracan characteristic of temporary aquatic environments whose persistence depends on the viability of dormant cysts accumulated in the sediment. This study tested the hypothesis that nauplii are more sensitive to malathion than cysts and that exposure to the latter...
