Abstract Cerrado is the largest and most biodiverse savannah worldwide. However, only a reduced amount of this ecosystem conserved, in last decades, vast agricultural expansion resulted substitution native vegetation for exotic pasturelands. Insects are key components both ecosystems Cerrado, performing critical functions maintenance. Our goal was to evaluate how transformation natural into cattle pastures (exotic pastures) affects insect communities biome. We conducted meta‐analysis using data on species richness abundance assemblages from conserved pastures. The analysis based set 23 scientific articles. Fourteen studies focused Coleoptera nine Hymenoptera. Conserved encompassed higher insects than pastures, but their did not differ between these two habitats. dung beetle increases significantly disturbed over time. Synanthropic that thrive altered environments could be masking actual decline sensitive environmental disturbances provoked by results highlight consequences structural homogenisation That is, despite having similar open‐canopy structure, land‐use change leads significant loss species, resulting drastic simplification communities.

Abstract Campinarana is a fragile white‐sand rainforest ecosystem in Amazonia, where mining activities have been an important driver of landscape transformation, threatening biodiversity.

Dung beetles are one of the most charismatic animal taxa. Their familiarity as ecosystem service providers is clear, but they also play a range roles in variety different ecosystems worldwide. Here, we give an overview current state dung beetle research and changes prevalence topics collated corpus 4,145 peer-reviewed articles research, spanning from 1930 until 2024. We used text-analysis tools, including topic modelling, to assess how literature on has changed over this period. Most split into three distinct, related discourses–the agri/biological topics, ecological taxonomic topics. Publications ‘effect veterinary chemicals’ ‘nesting behaviour’ showed largest drop time, whereas relating ‘ecosystem function’ had meteoric rise low presence before 2000’s being prevelant last two decades.
