“…We found that ant species richness was remarkably constant across the chronosequence, conveying a high resistance to disturbance. However, ant richness has been reported to have idiosyncratic responses to chronosequences in the majority of studies, as some report an increase of species richness or diversity with regeneration time (Bihn et al, 2008; Rocha‐Ortega et al, 2018), while others found no such relationship (Belshaw & Bolton, 1993; Estrada & Fernández, 1999; Hethcoat et al, 2019; Schmidt et al, 2013; Staab et al, 2014). Ultimately, species richness changes depend on the species pool that is specialized to disturbed areas, which replace forest species during disturbance.…”

Regrowing secondary forests dominate tropical regions today, and a mechanistic understanding of their recovery dynamics provides important insights for conservation. In particular, land‐use legacy effects on the fauna have rarely been investigated. One of the most ecologically dominant and functionally important animal groups in tropical forests are the ants. Here, we investigated the recovery of ant communities in a forest–agricultural habitat mosaic in the Ecuadorian Chocó region. We used a replicated chronosequence of previously used cacao plantations and pastures with 1–34 years of regeneration time to study the recovery dynamics of species communities and functional diversity across the two land‐use legacies. We compared two independent components of responses on these community properties: resistance, which is measured as the proportion of an initial property that remains following the disturbance; and resilience, which is the rate of recovery relative to its loss. We found that compositional and trait structure similarity to old‐growth forest communities increased with regeneration age, whereas ant species richness remained always at a high level along the chronosequence. Land‐use legacies influenced species composition, with former cacao plantations showing higher resemblance to old‐growth forests than former pastures along the chronosequence. While resistance was low for species composition and high for species richness and traits, all community properties had similarly high resilience. In essence, our results show that ant communities of the Chocó recovery rapidly, with former cacao reaching predicted old‐growth forest community levels after 21 years and pastures after 29 years. Recovery in this community was faster than reported from other ecosystems and was likely facilitated by the low‐intensity farming in agricultural sites and their proximity to old‐growth forest remnants. Our study indicates the great recovery potential for this otherwise highly threatened biodiversity hotspot.

“…Se implementaron seis técnicas de muestreo en cada estación: cebos alimenticios, los cuales consisten en vasos desechables pequeños provistos en su interior de atún con azúcar: 1. ubicados en troncos de árboles a 1.50 m de altura en el fragmento de bosque y en los arbustos en la zona de pastizal; 2. trampas hipogeas enterradas aproximadamente a 10 cm de profundidad, y 3. trampas epígeas en la superficie del suelo. Las hormigas capturadas en los cebos se colectaron después de cuatro horas [16]. 4. colecta manual, entre trampa y trampa se realizó, en un tiempo fijo de 10 minutos/hombre en sitios como la hojarasca, troncos caídos y bajo las piedras [17] para un total aproximado de dos horas y media -hombre por transecto.…”

Abiotic factors can negatively or positively affect the structure of communities; studying these factors is important to identify the causes that structure ant communities; taking into account this situation and that in the Amazon foothills region, particularly in the Putumayo department, few studies have been carried out and there is insufficient knowledge about the ecology of many species, this research was aimed to evaluate the effect of environmental variables in the assembly of ants, evaluating the hypothesis: the assembly of forest and grassland ants reflect changes in environmental variables (ambient temperature, soil temperature and relative humidity). In the municipality of Orito, in a secondary forest of the Amazon foothills and its grassland matrix, a 100 m transect was traced, locating 10 stations 10 m apart, in these, ants were sampled with: pitfall traps, corner baits: arboreal, epigeal and hypogeal, leaf litter extraction and manual capture. With the averages of the environmental variables in each station and the diversity and richness data per month of sampling, the Poisson regression analysis was performed and with the data of the morphospecies and the averages of the measured variables, the principal component analysis was performed. The results indicated that, the ants assemblages did not reflect the changes of the variables, some species responded to these patterns. Therefore, to understand the dynamics of the functioning of the ecosystems of the Amazonian foothills, it is necessary to study the biology of each species; However, it was determined that, the habitats studied share generalist species and contain exclusive species that contribute to the diversity of ants in the Amazonian foothills, consequently the sites must be conserved.

These studies have successfully evaluated restoration and recovery from a variety of anthropogenic impacts.…”

Bioassessment evaluates ecosystem health by using the responses of a community of organisms that integrate all aspects of the ecosystem. A variety of bioassessment methods have been applied to aquatic ecosystems; however, terrestrial methods are less advanced. The objective of this study was to examine baseline differences in ant communities at different seral stages from clear cut to mature pine plantation as a precursor to developing a broader terrestrial bioassessment protocol. Comparative sampling was conducted at nine sites having four seral stages: clearcut, 5 year recovery, 15 year recovery, and mature stands. Soil and vegetation data were also collected at each site. Ants were identified to genus. Analysis of the ant data indicated that ants respond strongly to habitat changes that accompany ecological succession in managed pine forests, and both individual genera and ant community structure can be used as indicators of successional change. Ants exhibited relatively high diversity in both early and mature seral stages. High ant diversity in mature seral stages was likely related to conditions on the forest floor favoring litter dwelling and cold climate specialists. While ants may be very useful in identifying environmental stress in managed pine forests, adjustments must be made for seral stage when comparing impacted and unimpacted forests.
