TL;DR: In this article, the effects of the stage of plant succession, from dense manuka scrub through to climax mixed kauri rain forest, and the openness of the undergrowth on the isopod fauna are discussed.
Abstract: SUMMARY The isopod fauna of a number of reserves and other sites in the Auckland Province is described and compared. The effects of the stage of plant succession, from dense manuka scrub through to climax mixed kauri rain forest, and the openness of the undergrowth on the isopod fauna are discussed.

TL;DR: Soil bacterial diversity indices had significant positive correlation with the contents of total nitrogen, total phosphorus, total potassium, hydrolyzed nitrogen and available potassium in the soil and the relative abundance of Firmicutes, Planctomycetes, Verrucomicrobia, Parcubacteria and Actinobacteria among three understory management measures.
Abstract: Given the importance of undergrowth vegetation to plantation ecosystem, this study analyzed the effects of three kinds of understory management measures, including understory preservation, understory removal, and interplanting, on the soil bacterial diversity, community structure and relative abundance under large diameter timber plantation of Cunninghamia lanceolata using high-throughput sequencing technology. The relationship between soil physical and chemical properties and bacterial community diversity were analyzed. The results showed that Chao1, Ace and Shannon indices of soil bacterial communities of understory preservation were higher than those of understory removal and interplanting. Actinobacteria, Acidobacteria and Chloroflexi were the dominant bacteria groups in the soil of C. lanceolata plantation. Compared with understory removal and interplanting, the relative abundance of Proteobacteria, Planctomycetes, Firmicutes and Verrucomicrobia in the soil of understory preservation was relatively high, while that of Actinobacteria, Acidobacteria and Chloroflexi was relatively low. There were significant differences in the relative abundance of Firmicutes, Planctomycetes, Verrucomicrobia, Parcubacteria and Actinobacteria among three understory management measures. The contents of moisture, total nitrogen, total phosphorus, hydrolyzed nitrogen and available phosphorus in the soil were important factors affecting soil bacterial community structure. Soil bacterial diversity indices had significant positive correlation with the contents of total nitrogen, total phosphorus, total potassium, hydrolyzed nitrogen and available potassium in the soil.

TL;DR: Results of field exploration conducted at Brantas Watershed of East Java indicated that there were at least 154 species of undergrowth scrubs, 47 species of agriculture-plantation crops, and 59 species of road shelter trees.
Abstract: In support of healthy agriculture development to improve farmer’s prosperity status, soil remediation and land conservation efforts maybe relied on the use of biomass of local vegetation. Results of field exploration conducted at Brantas Watershed of East Java indicated that there were at least 154 species of undergrowth scrubs, 47 species of agriculture-plantation crops, and 59 species of road shelter trees. The native undergrowth vegetations had undergone enormous seasonal variations. Biomass of predominance vegetations, e.g. Psophocarpus tetragonolobus, Phaseolus lunatus, Flemingia, Mimosa somian, Acacia villosa, Cassia mimosoides, Mucuna could potentially be used as organic matter sources to improve availability of nitrogen and phosphorus in soils. The amount of nitrogen and phosphorus contributed of the plant biomass significantly correlated with quality of the biomass.

TL;DR: Yanbaru, the northern montane portion of Okinawa Island, has historically been dominated by evergreen bloadleaf forests with remarkably rich biota, but many parts of the forest are now being destroyed as a result of government policy.
Abstract: Yanbaru, the northern montane portion of Okinawa Island, has historically been dominated by evergreen bloadleaf forests with remarkably rich biota, but many parts of the forest are now being destroyed as a result of government policy. Although there are many endemic animals and plants in the remaining natural forests, many of them are now in imminent risk of extinction. The status of populations of vertebrate animals listed in the Red List is described. Species diversity in Yanbaru forests is possibly highest among all Japanese forests, and this may be a dominant cause of the evolution and maintenance of many endemic species. However, the diversity has been diminished by forest cutting and removal of forest undergrowth by government subsidies. Suspension of clear-cutting and undergrowth removal, and change of proposed helipad sites from natural forest areas are necessary to preserve the unique biota of this area.
