“…In reality, however, ant diversity decreased due to the richness decrease of forest-specialist ants (SLD) and the great abundance increase of disturbance-tolerant ants (OF). The different functional responses of ants to various disturbances such as land use, mining, and fire have been well established in Australia (Majer 1983;Andersen et al 2002Andersen et al , 2009.…”

Diversity decrease of ant (Formicidae, Hymenoptera) after a forest disturbance: different responses among functional guilds

Background: Disturbance is one of the main causes for determining diversity of natural communities. A 3-year (2003 to 2005) monitoring of ant communities at a Long-Term Ecological Research (LTER) site in South Korea revealed a drop of ant diversity due to a forest disturbance which was evidenced by decrease of leaf area index (LAI) associated with the dropping of tree branches. In order to determine the process of the decrease in diversity, we compared the annual change of functional ant guilds, which are composed of forest ground foragers (FGF), forest vegetation foragers (FVF), soil and litter dwellers (SLD), and open-land foragers (OF). Results: Four functional guilds of ants responded differently to the forest disturbance; FGF and SLD decreased, but OF and FVF increased. Species richness decreased, due to the decrease in SLD, and species evenness decreased mainly due to a sudden increase in an OF species, Formica japonica. Based on these findings, a mechanism is proposed for the decrease in ant diversity after the forest disturbance.

“…The simplified habitats created by management practices in commercial forests often favours generalist species and decrease the diversity of forest specialists such as litter-dwelling cryptic species (Andersen et al 2009), which require a complex litter layer. Generalist ants are more likely to find sufficient resources within a patch, as compared to specialist species, which have limited mechanisms of dispersal and prefer locally limited resources (Pacheco et al 2009).…”

community richness and composition across a gradient from Eucalyptus plantations to secondary Atlantic Forest. Biota Neotrop. 11(1): http://www.biotaneotropica.org.br/v11n1/en/abstract?inventory+bn00811012011.Abstract: Secondary forests and exotic tree plantations are expanding across tropical landscapes. However, our current understanding of the value of these human-dominated forest landscapes for invertebrate biodiversity conservation is still very poor. In this paper, we use the leaf-litter ant fauna to assess invertebrate diversity in one commercially managed Eucalyptus plantation (four years old), two abandoned plantations of different regeneration ages (16 and 31 years), and one neighboring secondary Atlantic Forest in Southeastern Brazil. There was a clear gradient in species richness from the secondary forest to the managed Eucalyptus plantation; richness and diversity peaked in secondary forest and in the older regenerating Eucalyptus plantation. Significantly more species were recorded in secondary forest samples than in Eucalyptus plantations, but Eucalyptus plantations had a similar level of richness. Furthermore, a non-metric multidimensional scaling analysis revealed clear differences in species composition between the younger managed Eucalyptus plantation (understory absent) and habitats with sub-developed or developed understory. Eucalyptus plantations were characterized by an assemblage of widespread, generalist species very different from those known to occur in core forest habitats of southeastern Brazil. Our results indicate that while older regenerating Eucalyptus plantations can provide habitat to facilitate the persistence of generalist ant species, it is unlikely to conserve most of the primary forest species, such as specialized predators, Dacetini predators, and nomadic species.

No entanto, nossa compreensão sobre o valor destas florestas para a conservação da biodiversidade de invertebrados ainda é incipiente. Neste trabalho, usamos a fauna de formigas de serapilheira para avaliar a diversidade desses insetos entre três florestas de Eucalyptus, sendo uma comercial (quatro anos de idade) e duas abandonadas em diferentes idades de regeneração (16 e 31 anos) e uma área de Mata Atlântica secundária. A riqueza total foi mais alta na floresta secundária e nos plantios de Eucalyptus abandonados há mais tempo. A densidade de espécies na floresta secundária foi significativamente maior quando comparado as plantações de Eucalyptus, mas não difere entre eucaliptais; análise de ordenação revelou diferenças na composição de espé...

“…For example, species richness can increase following single fire events (Neville et al, 1997;Andersen, 1988), with higher fire frequencies (Vanderwoude et al, 1997;Andersen et al, 2009;but see Wittkuhn et al, 2011) and can decrease with time-since-fire (York, 1994;Jackson and Fox, 1996). Here, species density as well as standardized species richness appeared to be resistant to individual prescribed fires.…”
