Dung beetles are one of the most representative groups insects associated with livestock, as they take advantage manure livestock for food and reproduction. They have been widely used a bio-indicator group to evaluate their responses land-use change other environmental disturbances by analyzing species diversity at different spatial temporal scales. However, impacts management practices, forms, history on dung beetle still poorly understood. This paper is an exhaustive systematic review existing peer-reviewed indexed literature taxonomic (species richness composition), functional diversity, ecological functions from provinces biogeographic domains in tropical grazing lands Neotropics. We analyzed timeline studies conducted so far, we detected increasing produced mainly South America. included frequent objectives, tendencies, software, statistical analyses.

Dung removal increases under higher dung beetle functional diversity regardless of grazing intensification

Nature Communications, Год журнала: 2023, Номер 14(1)

Опубликована: Дек. 6, 2023

Abstract Dung removal by macrofauna such as dung beetles is an important process for nutrient cycling in pasturelands. Intensification of farming practices generally reduces species and functional diversity terrestrial invertebrates, which may negatively affect ecosystem services. Here, we investigate the effects cattle-grazing intensification on field experiments replicated 38 pastures around world. Within each study site, measured managed with low- high-intensity regimes to assess between-regime differences beetle removal, whilst also considering climate regional variations. The impacts were heterogeneous, either diminishing or increasing richness, diversity, rates. more variable across sites than within sites. increased richness sites, while consistently enhanced independently cattle grazing intensity climate. Our findings indicate that, despite intensified stocking rates, services related decomposition can be maintained when a functionally diverse community inhabits human-modified landscape.

Season‐driven climatic variables influence the temporal patterns of functional diversity and taxonomic dissimilarity of dung beetles in introduced Brazilian pasture ecosystem

Ecological Entomology, Год журнала: 2024, Номер 49(4), С. 556 - 568

Abstract Understanding the processes and mechanisms that underlie spatiotemporal patterns of biodiversity is paramount relevance, given ongoing global climate land cover changes. Here, we investigated influence season‐related climatic variables on two dimensions dung beetle diversity (taxonomic functional) at different scales (alpha beta) within an introduced Brazilian pasture ecosystem. We sampled beetles over 52 consecutive weeks, comprising dry rainy seasons. related taxonomic functional to (temperature, precipitation humidity) using absolute values changes from samplings (Δ, differences between samplings). found higher species richness abundance in season. Changes caused effects only dispersion, temporal β‐diversity losses but not beetles. However, these are dependent In season, increased a decrease dispersion opposite pattern was Similarly, temperature decreases both beetles, with Season‐associated showed contrasting metrics. Temporal may be driven by variables, which can associated sorting or traits their thermal niche.

Habitat simplification affects functional group structure along with taxonomic and phylogenetic diversity of temperate‐zone ant assemblages over a ten‐year period

Oikos, Год журнала: 2024, Номер 2024(6)

Опубликована: Фев. 8, 2024

Biodiversity is declining at various scales due to habitat simplification. Nevertheless, there scarce information on how the biotic and abiotic changes linked simplification affect several diversity dimensions, such as taxonomic, functional, phylogenetic diversities. This study investigated whether transforming natural oak forests into induced grasslands affected species diversity, functional group structure, of ant assemblages inhabiting a temperate forest in central Mexico. We placed over 1000 pitfall traps five sampling events covering ten‐year period. used Hill numbers evaluate differences between vegetation types patterns time. Ant were classified stress‐related groups, which analyzed for their association with proportional abundance calculated standardized effect size mean nearest taxon distance quantify evolutionary history test non‐random within years. Species richness did not differ types, yet showed greater q = 1 2 orders. , also found three bioindicators each type vegetation. Regarding cold climate specialists associated forests. In contrast, generalist predominant grasslands. Higher an overdispersed structure was forest, whereas lower clustered pattern grassland. These results indicate that may number species, but rather increases relative reorganizes ecosystem, particularly shifting towards dominance closely related broad‐stress‐tolerant groups. highlight importance integrating further dimensions properly reassembly dynamics after simplification, understand mechanisms driving this biodiversity loss.

Abstract Humans have substantially transformed the global land surface, resulting in decline variation biotic communities across scales, a phenomenon known as “biological homogenization.” However, different biota are affected by biological homogenization to varying degrees, but this and underlying mechanisms remain little studied, particularly soil systems. To address topic, we used metabarcoding investigate biogeography of protists their prey/hosts (prokaryotes, fungi, meso‐ macrofauna) three human land‐use ecosystem types (farmlands, residential areas, parks) natural forest ecosystems subtropical temperate regions China. Our results showed that degree community largely differed between taxa functional groups protists, was strongly positively linked colonization ability Removal analysis introduction widespread, generalist (OTUs, operational taxonomic units) rather than loss narrow‐ranged, specialist OTUs major cause homogenization. This increase seemingly alleviated negative impact use on taxa, carried risk losing diversity. Finally, prey/host environmental conditions were also important drivers systems, with importance being more pronounced phagotrophic parasitic phototrophic protists. Overall, our study depends is resources conditions. Importantly, not diversity conservation efforts should target at highly sensitive local extinction, such parasites.

Importance of restoration of dung beetles in the maintenance of ecosystem services

Ecological Solutions and Evidence, Год журнала: 2024, Номер 5(1)

Опубликована: Янв. 1, 2024

Abstract Dung beetles have key roles in ecosystems including accelerating dung decomposition, improving nutrient cycling and influencing physical (such as structure) chemical pH available nutrients) soil properties. Without beetles, decomposition slows, is impaired, water infiltration decreases. face various threats, climate change, anthropogenic chemicals habitat degradation. However, there limited information on the restoration of areas where they been lost. The framework utilized this review considers three primary facets: environmental conditions, which encompass crucial abiotic features; biotic characteristics, involve all other species; focal species, denote native functional groups species that require reintroduction or re‐establishment. This aims to examine ecosystem services provided by highlight threats conceptualize a for these organisms.

Flood did not cause the taxonomic and functional homogenization of Chironomidae (Diptera) community in a Neotropical floodplain

Acta Limnologica Brasiliensia, Год журнала: 2024, Номер 36

Опубликована: Янв. 1, 2024

Abstract: Aim We investigated the hypothesis that flood decreases taxonomic and functional beta diversity of Chironomidae (Diptera) larvae among floodplain lakes, causing biotic homogenization. Methods collected benthic samples using a modified Petersen grab in 18 lakes period (March 2011) drought (September Upper Paraná River floodplain. compared periods multivariate dispersion analysis (PERMDISP). Results found similar between hydrological periods. Conclusions did not find evidence homogenization due to pulse. Our findings suggest other mechanisms besides increasing connectivity environmental similarity pulse may structure community, such as variation identity flood-tolerant morphospecies across lakes.
