Arthropods are considered ecosystem engineers and are essential to the brown food web as they transform the soil by consuming plant debris and depositing feces that serve as food sources for micro- organisms, therefore, fostering microbial population growth and dispersal. This research aimed to assess how restoration stages affect arthropod populations and to validate the alternative state hypothesis. Arthropod abundance was significantly higher in primary forest compared to other forests at different restoration stages: • Evolutionary history of plant communities in this forest type favors arthropod population growth (Dinnage et al. 2012). When focusing solely on the predatory arthropod community, the abundance difference across habitat type was not significant: • Tree species diversity does not have an effect on predatory arthropod abundance (Vehvilainem et al. 2008). These findings offer a useful foundation to better address ground-dwelling organisms in reforestation efforts in the Neotropics as they partially validate the alternative state hypothesis.

Arthropods collected across the four habitattypes (abandoned pasture M=445.5,secondary forest M=313, primaryselectively-logged M=465.4 and primaryforest M=609.8) totaled 14,622 individualsand were classified into four orders:Arachnida, Crustacea, Insecta, andCollembola.Total arthropod abundance was significantlyhigher in primary forest compared to theother forest types.
Predatory Arthropod Abundance per Habitat Type
Predatory arthropods were further identified and classified into 14 taxonomic groups. Additional test shows that total predatory arthropod abundance was not significantly different across forest types.
