“…Uma das explicações para a maior diversidade encontrada na área de Cerradão reside no fato de que habitats heterogêneos possuem condições ideais para o estabelecimento das espécies de formigas, tal como maior variedade de sítios para nidificação, de alimentos, microclimas e interações interespecíficas (HÖLLDOBLER; WILSON, 1990). Nesse aspecto, estudos comparativos da mirmecofauna em diferentes usos de solo, indicam que a diversidade de espécies de formigas tende a aumentar na medida que os ambientes apresentam uma vegetação, também mais diversificada , 2010;GOMES et al, 2013;LEMES;KÖHLER, 2017;SOUZA-CAMPANA et al, 2017;APOLINÁRIO et al, 2019).…”

“…Entre os grupos de insetos componentes da fauna epiedáfica, utilizados como bioindicadores da qualidade ambiental, destacam-se as formigas (APOLINÁRIO et al, 2019), por apresentarem muitos dos fatores exigidos aos bioindicadores, como: abundância local alta, riqueza de espécies local e global alta, muitos táxons especializados, facilidade de serem amostradas, facilidade de serem separadas em morfoespécies e sensibilidade às mudanças nas condições do ambiente (MAJER, 1983). Nesse sentido, diversos estudos utilizam as formigas como bioindicadores da qualidade do ambiente, comparando sua diversidade associada aos diferentes usos do solo, incluindo plantios comerciais de eucalipto (MARINHO et al, 2002;LEMES;KÖHLER, 2017;SOUZA-CAMPANA et al, 2017;APOLINÁRIO et al, 2019).…”

O Cerrado é o segundo maior bioma brasileiro e vem sofrendo com os impactos negativos em sua área original. Tais impactos podem ser mensurados por meio de bioindicadores, dentre os quais, destacam-se as formigas. Nesse contexto, o presente estudo objetivou avaliar a diversidade de formigas associadas a duas áreas de diferentes fitofisionomias do bioma Cerrado e um plantio de eucalipto, em Monte Carmelo – MG (18º43’29” S e 47º29'55" O). Para a caracterização da mirmecofauna, foram utilizadas armadilhas de queda, instaladas a 10 m de distância entre si, no interior de três áreas distintas: Várzea e Cerradão (vegetação típica do bioma Cerrado) e um plantio de Eucalyptus sp. As coletas foram realizadas mensalmente, de janeiro a dezembro de 2018. Em cada coleta utilizaram-se oito armadilhas por área, totalizando 24 armadilhas. Após 48 horas de exposição, o material coletado nas armadilhas foi recolhido e levado ao laboratório para triagem e sequente identificação. No período do estudo, foi encontrada a maior abundância de formigas na área de Eucalipto (749), seguidas das áreas Várzea (291) e Cerradão (274). As áreas avaliadas possuem a mesma riqueza de espécies de formigas, sendo que foram encontradas 17 espécies de formigas em cada área, o que corroborou com a curva de rarefação que não identificou diferença significativa entre as áreas. A área de Cerradão apresentou maiores índices de diversidade e equitabilidade (H´ = 2,07 e J´ = 0,73). O diagrama de Venn indicou que as três áreas compartilharam 10 espécies de formigas entre si. Nesse aspecto, a área de Cerradão apresentou Azteca alfari, Linepithema neotropicum e Ectatomma opaciventre, como espécies exclusivas, enquanto as demais áreas apresentaram duas espécies cada. Os índices de diversidade, equitabilidade e composição da mirmecofauna encontrados, caracterizam a área de Cerradão como um ambiente ecologicamente mais equilibrado.

“…Functional diversity trends in neotropical landscapes translate biodiversity into changing attributes to influence resilience and ecosystem functioning (Apolinário et al, 2019; Philpott & Armbrecht, 2006). The diverse roles and ubiquity of ants contribute to highlighting their potential as functional indicators (Tiede et al, 2017).…”

“…Human activities reduce structural complexity and transform resource opportunities as well as microclimatic and abiotic conditions for ants (Groc et al, 2014). The primary forest myrmecofauna, largely characterised by specialised competitive traits, tend to be replaced by omnivorous and generalist traits favoured by novel niches (Apolinário et al, 2019; García‐Martínez et al, 2015). Trampling by livestock, agricultural machinery and vegetation control cause additional simplification of ecosystems, inevitably limiting the range of available niches (da Silva et al, 2022).…”

1. Environmental stressors and changes in land use have led to rapid and dramatic species losses and a reduction in associated ecosystem services.2. Functional diversity has increasingly been suggested as an alternative for evaluating anthropogenic disturbances and restoration programs because it reflects different aspects of the relationship between biological diversity, ecosystem functioning and environmental constraints.3. Ants are important components of terrestrial food webs and a key group associated with diverse interactions and ecosystem processes.4. Additionally, their sensitiveness and rapid response to environmental changes pave the way for their use as informative metrics for monitoring several processes that threaten biodiversity and ecosystem services. 5. Consequently, ants' functional diversity might be considered leading edge indicators to assess ecosystem changes to ongoing anthropogenic disturbances.6. The purpose of this study was to gauge the usefulness of epigaeic and leaf-litter ants' functional responses towards measuring ecosystem degradation (and/or restoration) in the Brazilian Amazon. 7. Our results demonstrate that functional traits exhibited sensitivity to ongoing changes, as well as different responses to specific environmental disturbances.8. Communities supporting ants with specialised functional traits associated with pristine ecosystems suffered high species loss and were correlated with specific anthropogenic stressors. 9. The results obtained pinpoint the importance of pristine ecosystems for conserving unique functional attributes and biodiversity in neotropical forest landscapes. 10. We highlight the significance of further studies in this scope to guide environmental managers and practitioners in applying the best policies for integrated neotropical landscapes conservation, considering the competing interests of farmers, foresters and conservationists, but also the unpredictable effects of local and regional environmental changes.

“…The identification of ant fauna to the genus level followed baCCaro et al (2015). Next, ants were separated into morphospecies and identified to the species level whenever possible by comparison with previously identified individuals and based on ant species identification keys found in the literature, a process similar to that carried out by GoMes et al (2013) andaPolinário et al (2019). The insects of the orders Coleoptera, Hemiptera, and Orthoptera were collected, identified, and counted.…”

Ant functional groups and their effects on other insects in organic and conventional cropping areas

et al. 2023

The present research aimed to study the functional groups of ants in organic and conventional cropping areas and assess their influence on the abundance of other insects in agroecosystems. Sampling was carried out in eight rural properties with organic, and eight with conventional crops in Paraíba do Sul, state of Rio de Janeiro, Brazil. Fifteen pitfall soil traps were installed to collect ants in each property, in April and May 2016. The ants collected were dry-mounted and identified. The insect abundances of the orders Coleoptera, Hemiptera, and Orthoptera were also obtained. Ants were classified into seven functional groups. The functional group with the largest number of species was “omnivores that inhabit the soil and the leaf litter,” followed by “omnivores that inhabit the soil, the leaf litter, and the plants.” The group “omnivores that inhabit the soil and the leaf litter” showed the highest abundance of ants in both types of crops. The mean richness of functional groups was significantly higher in organic than in conventional crops. We only observed the effect of the abundance of ants of the group “omnivores that inhabit the soil, the leaf litter, and the plants” on the abundance of coleopterans in conventional crops. Hence, areas with organic crops are more favorable for maintaining an ant fauna with higher functional diversity than areas using the conventional cropping system.
