The Impact of Eucalyptus and Pine Plantations on the Taxonomic and Functional Diversity of Dung Beetles (Coleoptera: Scarabaeidae) in the Southern Region of Ecuador

Biology, Journal Year: 2024, Volume and Issue: 13(10), P. 841 - 841

This study sheds light on the complex relationship between land use, biodiversity, and functional traits of dung beetles in Ecuador. The results indicate that richness abundance vary across different uses regions, with forests generally having a positive impact, while eucalyptus pine plantations have negative effect certain areas. Specific indicator species, such as

Restoration of Natural Habitats as a Nature-based Solution for Sustaining Insect Biodiversity to Ensure Sustainable Food Production

Global Journal of Ecology, Journal Year: 2024, Volume and Issue: 9(2), P. 146 - 155

The rapid loss of natural habitats and resulting biodiversity in insect taxa is a serious concern that will impact future food production. Insect decline can be mainly attributed to the intensification agriculture with main drivers being habitat loss, fragmentation, use agro-chemicals. To mitigate pressure on we urgently need prioritize restoration land within agricultural landscapes. Changes landscapes as intensifies were investigated an Afromontane biome South Africa, using dung beetle assemblages indicators transformation. Five localities chosen for monitoring grassland Eastern Free State, Africa. A total 27 species classified 15 genera collected study area during November 2023. Land change from causes community structure beetles some functional groups becoming more dominant, while others disappear intensity increases. For efficient ecosystem functioning habitats, integrated approach specific necessary. protection large areas, degraded promotion livestock crops are adapted environment essential.

Influence of landscape and livestock management on dung beetle diversity in tropical cattle pastures

Research Square (Research Square), Journal Year: 2022, Volume and Issue: unknown

Published: July 8, 2022

Abstract To achieve a balance between conservation and livestock production in the context of highly degraded tropical landscapes, we need research approach that considers relationships among biodiversity, landscape structure, farming practices. Given dung beetles are sensitive to both changes local scale management practices, these insects used as ecological indicators provide information regarding pasture’s health. We assessed response beetle diversity practices structure 22 cattle pastures from regional relictual dominated by productive land uses. Livestock were best predictors for species richness, Shannon diversity, number individuals. Macrocyclic lactone use was negatively related richness individuals; high densities increased studied ranches. Patches old-secondary forest cover had positive significant relationship with every variable predictor biomass, but also contributed maintaining pastures, suggesting secondary forests favorable microclimatic conditions landscapes. This study provides evidence modified landscapes rational macrocyclic lactones can be useful tools favor ecosystem services they provide, thus ensuring pasture

Although the loss of native habitat is primary cause biodiversity change worldwide, understanding biodiversity's response to requires considering influence introduced anthropogenic habitats in modified landscapes.My thesis examined how and gain affected patterns, using Scarabaeinae beetles (aka dung beetles) as a study system.I analyzed various dimensions reduction tropical forest paired along gradient Brazilian Atlantic Forest.In first chapter, I observed changes beetle diversity this gradient.Deforestation was associated with patterns biotic differentiation, increases alpha gamma richness, "positive" responses that can be partly understood light history Forest proximity taxa sources open areas.In second explored composition structure communities one type may related those adjacent types.The interaction between gradients environmental influences community cover reduction.Findings reveal complex interplay factors shaping within habitats.Landscape structure, species associations, conversion significantly impacted composition, owing combined spillover, invasion, extinction.Landscape configuration, such increased edges pasture, turnover, underscoring importance managing areas preserve landscape biodiversity.This research brings crucial contributions influence, transcending prevalent geographical taxonomic biases.These findings guide strategies for conservation restoration landscapes, essential fundamental ecological processes.
