Species distribution model of invasive alien species Acacia nilotica for Central-Eastern Indonesia using Biodiversity Climate Change Virtual Laboratory (BCCVL)

Abstract

Abstract. Sutomo, Van Etten E. 2017. Species distribution model of invasive alien species Acacia nilotica for Central-Eastern Indonesia using Biodiversity Climate Change Virtual Laboratory (BCCVL). Trop Drylands 1: 36-42. Climate change may facilitate alien species invasion into new areas. This study uses Biodiversity and Climate Change Virtual Laboratory to develop a species distribution model (SDM) of Acacia nilotica (L.) Willd. ex Delile. based upon its naturalized distribution to project the potential distribution of A. nilotica throughout tropical environment of Indonesia under current and future climate conditions. Global biodiversity information facility database was utilized to obtain the species occurrences data. The climate factors were precipitation and temperature layers, available in Worldclim current conditions at 2.5 arcmin. We used Generalized Linear Model. The result was then projected to the year 2045 using RCP 8.5 greenhouse gas emissions scenarios to influence the climate model (CSIRO Mark 3.0. with 30'' resolution). Final results show that global climate change is likely to increase markedly the potential distribution of A. nilotica in Indonesia. By the year 2045, A. nilotica is most likely to spread to eastern parts of Indonesia. In general, our model performance is good (AUC = 0.82), however, like many other SDMs, it does not take into account biotic interactions as well as other environmental factors. Nonetheless, climatic suitability is an essential requirement for successful establishment of an invasive species and species distribution models that can disclose general patterns and convey useful estimate.

Review: The invasion of Acacia nilotica in Baluran National Park, Indonesia, and potential future control strategies

“…As of 2016, the prickly acacia has invaded more than 6000 hectares of BNP (Padmanaba et al 2017) and recently not only invading savannah but also the dry forest in BNP (Sutomo et al 2019). The invasion is predicted to be more severe in the future due to climate change (Sutomo and Etten 2017). Despite the invasion severity, the nutrient contents in the savannah soil remain stable (Samsoedin and Siregar 1997).…”

“…Despite the invasion severity, the nutrient contents in the savannah soil remain stable (Samsoedin and Siregar 1997). Based on the Habitat Suitability Index (HSI), the eastern part of the coastline area of Indonesia will likely be more prone to invasion (Sutomo and Etten 2017). East Java, Bali, Lombok, Sumba, Kupang, and West Papua have the highest risk, as trees have already reached Bali and Kupang (Sutomo and Etten 2017).…”

East Java, Bali, Lombok, Sumba, Kupang, and West Papua have the highest risk, as trees have already reached Bali and Kupang (Sutomo and Etten 2017). However, the model did not incorporate the effect of climate change on native species that potentially interact with the prickly acacia.…”

Smart farming: modeling distribution of Xanthomonas campestris pv. oryzae as a leaf blight-causing bacteria in rice plants

“…This technique is known as Species Distribution Modeling (SDM), Habitat Suitability Index (HSI), or Ecological Niche Model (ENM). On a broader scale, this application can also be used for various research such as: Identifying possible prospective locations to find an endangered species [14]; Assist the design of effective monitoring for an Invasive Alien Species (IAS) [15]; Identifying suitable sites for reintroduction of a species [16]; Assessing the impact of a climate (or climate change), land use (or land use changes) on the distribution pattern of a species [17]. This paper aims to conduct a species distribution model of leaf blight-causing bacteria, Xanthomonas campestris pv.…”
