“…Soil arthropods are litter transformers and predators—they contribute to organic matter decomposition and nutrient cycling (Lavelle et al, 1997). Yet, their ecology, trophic interactions and function in ecosystems are not well understood and are the subject of ongoing research focused on the impact of environmental factors (Lamarre et al, 2016; Soares et al, 2021), the effect of short‐term disturbances (Migge‐Kleian et al, 2007), seasonality (Grimbacher et al, 2018), habitat fragmentation (Vasconcelos & Bruna, 2012), changes during forest recovery (Hopp et al, 2010; Tayllon Serra et al, 2021) or the basic structure of food webs (Lagerlöf et al, 2017; Pollierer et al, 2021).…”

Forest soil and leaf litter support diverse arthropod mesofauna for which diversity dynamics is challenging to study due to the high number of species and specimens, small body size and limited taxonomic knowledge. Immature stages (larvae) are even harder to identify than adults, as their morphology is largely unknown. Therefore, larvae are often ignored, even though they may form a substantial proportion of specimens collected, are less mobile than adults and their exclusion may provide an incomplete diversity profile. Here, we use Oxford Nanopore DNA barcoding to investigate whether the inclusion of larvae provides a more complete taxonomic, phylogenetic and functional diversity profiles in leaf litter beetles (Coleoptera) from a subtropical forest in Taiwan. Our results indicate that larvae represent up to 38% of beetle specimens per sample, but most of them belong to 2–3 common species. Larvae of most beetle species are rarely collected repeatedly or in multiple specimens, possibly due to special habitat requirements or high seasonality. Taxonomic, phylogenetic and incidence‐based functional diversity measures were not affected by the exclusion of larvae in the Staphylinidae dataset but were strongly biased in all‐beetle dataset, especially when only common or abundant species were considered. Taxonomic beta diversity was not affected by the omission of larvae. Our results indicate that immature stages may be omitted in ecological studies of arthropods in case both adults and larvae co‐occur in the same habitat, and the sites are sampled repeatedly. Caution is needed (1) in groups in which larvae and adults do not inhabit the same environment or strongly differ in biology, (2) when rare species are omitted or (3) when functional diversity is calculated from abundance data.

“…Therefore, the capacity of the veredas to maintain high levels of humidity in the soil emphasizes its hydrological importance, since it ensures the perennity of water courses. This also provides a milder environment for the fauna of the Cerrado, which can find shelter and food during the dry season (Brandão 1991; Soares et al 2021b).…”

“…High levels of moisture and environmental and biological diversity make veredas important for the maintenance of wildlife resources (Brandão et al 1991; Soares et al 2021b), environmental services, such as carbon immobilization (Soares et al 2021a; Wantzen et al 2012), and hydrological balance (Munhoz et al 2011). The relationship between the chemical characteristics of the soil and the zones of the veredas is complex and may be influenced by other factors such as geomorphical characteristics (Ramos et al 2006; Campos et al 2013), and surrounding land use (Sousa et al 2015).…”

This work aimed to identify: (1) heterogeneity patterns in veredas, considering tree/shrubby regeneration and chemical and physical characteristics of the soil;(2) how the vereda zones (edge, intermediate and core) can influence the tree/ shrubby regeneration and (3) which microenvironmental characteristics determine the distribution of native tree/shrubby regenerants and of the invasive species Pinus caribaea Morelet. For this, we collected environmental and biophysical data and sampled the regeneration of tree/shrubby species in 30 plots in two different veredas. The moisture and chemical characteristics of the soil, and regeneration composition were similar among the vereda zones, but showed important variations among sample units. In addition to soil moisture, soil chemical elements and canopy coverage characteristics also formed environmental gradients. The native tree/shrubby species occupied different positions along the environmental gradient of the veredas. The invasive species P. caribaea was more concentrated in less declined sites, in more basic and more humid soils, together with most native species. In general, the results demonstrate the absence of clear zoning, as well as the importance of environmental heterogeneity and the control of biological invasion for the maintenance of native tree/shrub regeneration.
