Abstract Clearing of woodlands is used by graziers to promote pasture production, even though understanding of impacts of clearing on native fauna is lacking. We evaluate impacts of clearing on biodiversity by comparing invertebrates associated with ground-layer vegetation of cleared woodlands (grasslands) to that of nearby uncleared woodlands. Two replicates of grasslands consisting of pastures dominated by introduced grasses were compared with two woodlands at each of four locations. The adjacent riparian forest to each grassland and woodland site allowed evaluation of the effect of woodland clearing on the adjacent riparian zone. All habitats were grazed. Invertebrates of ground-layer vegetation were sampled using three suction subsamples of 1m 2 at each site. Grasslands had significantly lower order richness and abundance of herbivores, pollinators and macroinvertebrates (food for birds) than the woodlands, whereas the riparian forests closely resembled each other in all metrics. Invertebrate assemblages of grasslands also differed significantly from those of the woodlands. BEST analysis showed that groundcover and leaf-litter percentage cover correlated strongest with invertebrate composition. This study has demonstrated that grazing management relying on clearing of fertile grassy woodlands of the rangelands of Central Queensland alters invertebrate diversity and assemblage. Thus, tree clearing not only leads to biodiversity losses in the canopy layer, but also in the ground-layer vegetation. Implications for insect conservation Pastoralists have the capacity to improve outcomes for invertebrate biodiversity by maintaining groundcover (ground-layer vegetation and litter cover) above 80%, by encouraging native pastures over introduced species such as Buffel Grass and by retaining native woodlands.

Abstract Bees are the most important pollinators and, like many other insects, are facing a global decline that threatens crop pollination services. Both honey bees and some wild bee species are used commercially for pollination, including pollination in blueberry and cherry orchards. In our study, we assessed bee visits to experimental blueberry and cherry orchards immersed in an urban landscape to understand how air-temperature affects the potential contribution of honey bees and wild bees to pollination services. The potential contribution to pollination services was estimated using the Pollination Importance Value index, where the pollen collected by the floral visitor is a determining variable. In our study, bumble bees and honey bees were the most important floral visitors in the orchards, followed by the wild bee Anthophora plumipes . We found that honey bees were affected by changes in air-temperature and their decrease in the potential contribution to pollination services was offset by the niche complementarity provided by bumble bees. Implications for insect conservation Even small changes in air-temperature can alter bee communities by affecting bee species susceptible to low temperatures. Our work is a first assessment of how climate change may affect the complementarity of pollinator communities in orchards. We suggest that strategies to mitigate local air-temperature changes in urban areas, focusing primarily on these species, could potentially have cascading effects that would support the overall pollination services provided by bee communities.

Abstract We assessed the Caraboidea communities of Gorongosa National Park (GNP) in Mozambique. Influence of tropical rainfall, after a long period of drought, was evaluated on alpha and beta diversity of tiger- and ground-beetles in the main habitat types of the park: miombo forests, mixed forests, transitional forests, and grasslands (open savannas). Tiger- and ground-beetle communities were sampled by pitfall traps set up in 25 sites of each habitat type along three sampling periods, comprising the transition of dry season to the wet season. After the first rainfall, an increase in alpha diversity was observed across GNP habitats, particularly in grasslands. Higher values of beta diversity were observed between the dry and wet sampling periods, particularly in grasslands. In contrast, community dissimilarities between sampling periods were not significant in the transitional forests. Community body size in grasslands increased after the rainfall, partly due to the occurrence of caraboid species that were exclusive of forest habitats during drought. Transitional forests, as ecotone habitat areas, appeared to support grassland species during drought, serving also as a source of forest species that may colonize the open areas in the wet season. Forest species will probably be more threatened by climate aridification and future landscape changes due to climate change.

Abstract Rapid urbanization is among the factors that decrease insect diversity. However, by offering suitable habitats, green roofs could lessen this adverse effect. Certain factors, like a nearby public garden, could be useful predictor variables to analyze to what extent green roofs can support insect communities. The study aimed to measure the insect diversity on intensive green roofs located near public gardens and on more isolated green roofs, within an urban setting. Insect species richness, abundance, and assemblages on the green roofs near public gardens differed from those on isolated green roofs. Results indicate that green roofs near public gardens will host more species, especially pollinators, consequently lessening urbanization’s negative effect. To properly understand how landscape factors impact insect communities on green roofs, future studies on green roofs’ biodiversity should consider public gardens and their influence on urban biodiversity. Implications for insect conservation The planning and establishment of a green roof near public gardens would probably enhance biodiversity conservation in an urban setting.
