“…The dominance of dipterans in Malaise trap samples across the three anthropogenic forests was similar to previous findings, for example, Zhang et al (2016) reported that the collections from traps deployed in a tropical forest in southern mainland China comprised 43% dipterans ( n = 848). Similarly to Coleoptera and Lepidoptera, the proportion of Diptera was significantly affected by the interaction between forest type and maximum temperature.…”

Arthropod communities in the tropics are increasingly impacted by rapid changes in land use. Because species showing distinct seasonal patterns of activity are thought to be at higher risk of climate-related extirpation, global warming is generally considered a lower threat to arthropod biodiversity in the tropics than in temperate regions. To examine changes associated with land use and weather variables in tropical arthropod communities, we deployed Malaise traps at three major anthropogenic forests (secondary reserve forest, oil palm forest, and urban ornamental forest (UOF)) in Peninsular Malaysia and collected arthropods continuously for 12 months. We used metabarcoding protocols to characterize the diversity within weekly samples. We found that changes in the composition of arthropod communities were significantly associated with maximum temperature in all the three forests, but shifts were reversed in the UOF compared with the other forests. This suggests arthropods in forests in Peninsular Malaysia face a double threat: community shifts and biodiversity loss due to exploitation and disturbance of forests which consequently put species at further risk related to global warming. We highlight the positive feedback mechanism of land use and temperature, which pose threats to the arthropod communities and further implicates ecosystem functioning and human well-being. Consequently, conservation and mitigation plans are urgently needed.

Species richness and turnover among indigenous and introduced plants and insects of the Southern Ocean Islands

Simultaneously investigating variation in species richness and turnover for indigenous and introduced communities holds great promise as a means to understand the relative contributions of ecological processes to community structure. Such insight will advance understanding of the ways in which environmental change may affect future community dynamics. Using a recently developed multi‐site turnover metric, zeta diversity (ζ), we explored species turnover patterns across indigenous and introduced insect and vascular plant communities of the Southern Ocean Islands. In addition, we used updated species occurrence and high‐resolution environmental data to reexamine previously described patterns and drivers of species richness across the region. Species richness variation in indigenous insect and vascular plant communities was largely explained by island isolation and temperature, whereas human visitation frequency was strongly associated with introduced species diversity of both groups. Indigenous communities of both plants and insects had faster rates of species turnover across sites and less inter‐island connectivity than their introduced counterparts. Zeta diversity analyses suggested that stochastic processes were more influential than niche‐related processes on the observed patterns of turnover of indigenous insects. Meanwhile, turnover patterns of introduced insects and indigenous and introduced vascular plants were indicative of the dominance of niche‐related processes. These outcomes highlight very different diversity patterns across indigenous and alien communities and indicate that different ecological processes may underlie diversity variation across these islands and taxonomic groups.

“…Greater levels of arthropod biodiversity in native forest is not a surprise, given their more diverse vegetation structures and species compositions, which are well known to be positively correlated with arthropod diversity (Castagneyrol & Jactel, ; Haddad et al, ; Stork, Mcbroom, Gely, & Hamilton, ; Zhang et al, ), but the greater diversity and similarity of mixed plantations to native forests is somewhat surprising, especially as they mostly just comprise small‐scale monocultures, planted in checkerboard pattern. However, planting different tree species near each other not only provides more diverse vegetation per se but also, because the species vary in height and three‐dimensional structure, almost certainly allow greater sunlight penetration to the understorey, which in turn should result in greater availability of food and other resources.…”

Aim: China's Grain for Green Program (GFGP) is the largest reforestation programmein the world and has been operating since 1999. The GFGP has promoted the establishment of tree plantations over the restoration of diverse native forests. In a previous study, we showed that native forests support a higher species richness and abundance of birds and bees than do GFGP plantations and that mixed-species GFGP plantations support a higher level of bird (but not bee) diversity than do any individual GFGP monocultures (although still below that of native forests). Here, we use metabarcoding of arthropod diversity to test the generality of these results. Location: Sichuan, China.Methods: We sampled arthropod communities using pan traps in the land cover types concerned under the GFGP. These land use types include croplands (the land cover being reforested under the GFGP), native forests (the reference ecosystem as the benchmark for the GFGP's biodiversity effects) and the dominant GFGP reforestation outcomes: monoculture and mixed-species plantations. We used COI-amplicon sequencing ("metabarcoding") of the arthropod samples to quantify and assess the arthropod community profiles associated with each land cover type.Results: Native forests support the highest overall levels of arthropod species diversity, followed by mixed-species plantations, followed by bamboo and other monocultures. Also, the arthropod community in native forests shares more species with mixed-species plantations than it does with any of the monocultures. Together, these results broadly corroborate our previous conclusions on birds and bees but show
