Asynchrony in population abundance can buffer the effects of environmental change leading to greater community and ecosystem stability. Both environmental (abiotic) drivers and species functional (biotic) traits can influence population dynamics leading to asynchrony. However, empirical evidence linking dissimilarity in species traits to abundance asynchrony is limited, especially for understudied taxa such as insects.

It is unclear whether freshwater invertebrates, which are key providers of ecosystem services, are also declining. We addressed this question by analysing a long-term dataset of macroinvertebrate abundance collected from 2002 to 2019 across 5009 sampling sites in English rivers.

- Perseverance's Mastcam-Z captures detailed stereo and multispectral images, offering a comprehensive view of the geology in Jezero crater on Mars.
- The rocks depicted show features indicating they are of igneous or impactite origin, with minimal water alteration and include various mineral compositions like mafic silicates and olivine.
- Additional imaging reveals important atmospheric conditions, including dust variations and unique interactions caused by dust devils and the Ingenuity helicopter, which aid in understanding Mars' environment and assist in rover operations.
