“…For logistical reasons, ants were only surveyed at sites D1, 3, and 4. Time since fire and environmental variables (canopy cover, understory vegetation cover, plant litter depth and dry litter weight) were recorded based on Neoh et al [14]. The level of ecological degradation in the peats was categorized based on Page et al’s classification [30] (Table 1).…”

“…The feeding natures of termites and ants suggest that they may be fundamental in food web dynamics in a given tropical peat swamp forest and may help maintain the stability of the ecological system. Termite and ant diversity usually decreases with increased land use disturbance [13,14,15]. The relatively high temperature of tropical peat fires and their long-lasting smoldering effects elicit greater detrimental impacts on soil-dwelling insects (e.g., termites) [16].…”

Fire has become a common feature in tropical drained peatlands, and it may have detrimental impacts on the overall biodiversity of the forest ecosystem. We investigated the effect of fire on termite and ant assemblages and the importance of remnant forest in restoring species diversity in fire-impacted tropical peat swamp forests. The species loss of both termites and ants was as high as 50% in some fire-impacted peats compared to remnant forests, but in most cases the species richness for termites and ants was statistically equal along the land uses surveyed. However, a pronounced difference in functional group composition of termites was detected. In particular, sites close to remnant forests contained two additional termite feeding groups so that they shared a similar composition structure with remnant forests but were significantly different from sites distant from remnant forests. In general, ants were resilient to fire, and the similarity index showed a high degree of similarity among ant communities in all land uses surveyed. The Shannon diversity index for termites and ants decreased with increasing distance from the remnant forests and level of ecological degradation. Peat vegetation variables and ecological degradation were important in shaping termite and ant communities in the tropical peatlands, but their relative importance was not significant in fire-impacted peats regardless of distance from the remnant forests. This study highlights the importance of remnant forests as a biodiversity repository and natural buffer that can enhance species diversity and recolonization of forest-adapted species.

“…The litter layer is a challenging system to study because of the high species richness and exceptional phylogenetic diversity of the fauna. Most research has therefore either used litter bags with mesh sizes chosen to exclude invertebrates of different sizes 3 , or has focused on a single taxonomic group 6 – 8 . Recently, however, DNA metabarcoding has been used to overcome the challenge of high taxonomic diversity and to give a broader view of the diversity and composition of the litter fauna 9 – 11 .…”

Seasonal changes in the diversity and composition of the litter fauna in native forests and rubber plantations

The litter layer of tropical forests supports a significant fraction of total arthropod diversity and decomposition of this layer is the main pathway by which nutrients are returned to the soil and CO2 to the atmosphere. Conversion of tropical forests to agriculture is the main threat to biodiversity and ecosystem services, and understanding effects on the litter layer is important for understanding and mitigating these impacts. We used high through-put DNA sequencing of the mitochondrial cytochrome c oxidase subunit I (COI) gene to assess seasonal changes in the diversity and composition of the litter fauna at five matched pairs of native forests and rubber plantations in tropical SW China every month for a year, and measured the environmental factors expected to drive intra-annual variation. Forests and rubber had very different arthropod assemblages throughout the year, with forests more species-rich than rubber in all months except February. Very high rates of intra-annual turnover in species composition in both forests and rubber were associated with seasonality in environmental variables, with the influence of particular variables differing among taxa. Tropical arthropods are very sensitive to seasonality and sampling at only one time of the year captures only a subset of the total community.

“…Furthermore, disturbed habitats experience different environmental conditions from undisturbed habitats (Van Nuland & Whitlow, ). Disturbed habitats support fewer microhabitats, such as leaf litter and logs (Loyola et al, ; Van Nuland & Whitlow, ), which are important niche for flightless arthropods (Neoh et al, ). Our results support previous studies, which demonstrated that arthropod assemblages are altered by the land use type (Mauda et al, ; Melliger et al, ; Van Nuland & Whitlow, ).…”
