“…Tingginya nilai INP Alternanthera philoxeroides di Danau Batur diakibatkan oleh sifat vegetasi ini yang dapat hidup secara amfibi, memiliki kemampuan bertahan hidup yang tinggi walaupun hanya sedikit terendam air, mengingat sifat danau yang volume airnya dapat berubah-ubah seiring waktu. Selain itu, jenis vegetasi ini memiliki toleransi suhu yang baik, Alternanthera philoxeroides dapat hidup dalam suhu 4 o C selama 72 jam (3 hari) dan dapat mentolerir suhu tahunan rata-rata antara 10-20 o C disamping suhu optimum untuk melakukan fotosintesis, yaitu 30 -37 o C. Vegetasi ini juga mampu bertahan hidup dalam air yang berkondisi tercemar bahan kimia dan dapat mengubah siklus nutrisi dari badan air (Bassett et al, 2012).…”

Batur lake is an aquatic natural resource that has a very important value in terms of ecological functions and economic functions. Batur lake gets pressure due to discharges of various types of waste generated from plantation activities, community settlements, cultivated feed residues in floating net cages, tourism activities and water transportation waste. It can cause ecosystems disruption in Batur lake, especially on the aquatic vegetation. This study aims to determine the species diversity and the influence of community activities on aquatic vegetation in Batur lake. This research was conducted from February to March 2017 at Batur Lake using quantitative descriptive method. Sampling was conducted at five stations by taking data and samples of aquatic vegetation, measuring water quality (temperature, pH, DO, clarity and turbidity) and water samples for testing nitrate, phosphate and sulfide acid content. The aquatic vegetation species that found were seven types, namely Alternanthera philoxeroides, Persicria decipiens, Phragmites australis, Eicchornia crassipes, Ceratophyllum demersum, Pistia stratiotes and Azolla pinnata. The value of diversity is in the low category. Uniformity of aquatic vegetation in Lake Batur waters ranged from 0.62257 - 0.874. The dominant value ranges from 0.22435 - 0.61563. The highest density values were found in species of Alternanthera philoxeroides at station II with 880 ind/m2 and 40 ind/m2 of Persicaria decipiens as the lowest density species. The water quality parameters give a significant influence on the growth of aquatic vegetation in Batur lake waters.

“…Many species in the orders Hemiptera (true bugs) and Lepidoptera and a few Thysanoptera (thrips) and Coleoptera (beetles) species are considered host specific during some or all life stages (Triplehorn & Johnson ), and these species may be greatly affected by increased abundance of novel plants (Tables ). When an invasive plant dominates the vegetation community, hemipterans may be less abundant (e.g., Spyreas et al ; Holmquist et al ; Bassett et al ) or absent (e.g., Samways et al ; Derraik et al , Table ), resulting in changes in composition. Although little research has focused on nonagricultural systems, Thysanoptera also may be less abundant or absent in areas dominated by invasive plants (e.g., Derraik et al ; Lindsay & French ; Holmquist et al , Table ).…”

Non-native plants have invaded nearly all ecosystems and represent a major component of global ecological change. Plant invasions frequently change the composition and structure of vegetation communities, which can alter animal communities and ecosystem processes. We reviewed 87 articles published in the peer-reviewed literature to evaluate responses of arthropod communities and functional groups to non-native invasive plants. Total abundance of arthropods decreased in 62% of studies and increased in 15%. Taxonomic richness decreased in 48% of studies and increased in 13%. Herbivorous arthropods decreased in response to plant invasions in 48% of studies and increased in 17%, likely due to direct effects of decreased plant diversity. Predaceous arthropods decreased in response to invasive plants in 44% of studies, which may reflect indirect effects due to reductions in prey. Twenty-two percent of studies documented increases in predators, which may reflect changes in vegetation structure that improved mobility, survival, or web-building for these species. Detritivores increased in 67% of studies, likely in response to increased litter and decaying vegetation; no studies documented decreased abundance in this functional group. Although many researchers have examined effects of plant invasions on arthropods, sizeable information gaps remain, specifically regarding how invasive plants influence habitat and dietary requirements. Beyond this, the ability to predict changes in arthropod populations and communities associated with plant invasions could be improved by adopting a more functional and mechanistic approach. Understanding responses of arthropods to invasive plants will critically inform conservation of virtually all biodiversity and ecological processes because so many organisms depend on arthropods as prey or for their functional roles, including pollination, seed dispersal, and decomposition. Given their short generation times and ability to respond rapidly to ecological change, arthropods may be ideal targets for restoration and conservation activities.
