The impact of Methyl parathion and Carbaryl was evaluated on an ecologically important soil Collembola, Cyphoderus sp. Enzyme characteristics demonstrate substrate optimum at 1 10(-2) mol/L temperature optimum at 30 degrees C with a pH requirement of 8.0. In vivo inhibition of whole body AChE reveals higher degree of inhibition by LD50 dose of Methyl parathion as compared to that of Carbaryl where maximum inhibition was noticed at the agricultural dose.

Panama, located in the heart of the Mesoamerican hotspot, harbors an extraordinary species diversity across the Tree of Life. The Collembola species of the genus play an important role in soil biological processes such as decomposition, being used to monitor soil health and functional parameters. However, the limitation of morphological characters and molecular resources hampers the evaluation of local soil diversity.

An estimated 467 kt of plastic used in agriculture annually end up in European soils, potentially breaking down into secondary microplastics (MPs). Not much is known about the possible effects of these MPs on organisms residing in the soil. To properly assess their environmental risk, experimental data is needed on the toxicity of MPs to the survival and reproduction of model organisms.

Collembola play a key role in soil ecosystems by decomposing organic matter. Most of them inhabit the upper layers of the soil and are susceptible to contamination present in the pore water. These arthropods serve as model organisms in ecotoxicology for short and long-term exposure.

Soil arthropods are important biological components of the soil food web, which are highly sensitive to environmental disturbances and can rapidly respond to changes in the external environment, then reflect the stability and health of the soil ecosystem. We investigated the community structure of soil arthropod and their responses to grazing intensity along soil depth (from topsoil to subsoil) through a manipulated grazing treatment with four intensity levels (no grazing, light grazing, moderate grazing and heavy grazing) in an alpine grassland in the Qinghai Lake basin. The results showed that: (1) Collembola was the dominant group in the experimental site.

Covering up to September 2024Collembola, commonly known as springtails, are abundant and important members of soil ecosystems. Due to their small size and hidden life, not much is known about their secondary metabolites. This chemistry is remarkably different from that of insects, with which they share a common ancestor, although they diverged already around 450 mya.
