Changes in soil bacterial community diversity following the removal of invasive feral pigs from a Hawaiian tropical montane wet forest

Abstract: Nonnative, invasive feral pigs (Sus scrofa) modify habitats by disturbing soils and vegetation, which can alter biogeochemical processes. Soil microbial communities drive nutrient cycling and therefore also play important roles in shaping ecosystem structure and function, but the responses of soil microbes to nonnative ungulate removal remains poorly studied. We examined changes in the soil bacterial community over a ~25 year chronosequence of feral pig removal in tropical montane wet forests on the Island of … Show more

“…While several studies have investigated the effects of species invasions on environmental microbiomes, we still lack a generalized consensus across different environmental microbiomes and systems. Previous studies have found that invasive species increased environmental microbial diversity [13,19], while others reported a decrease [15,20,29]. However, the majority of studies did not analyze the microbial diversity, as they used techniques that did not allow for such analysis, or reported no changes [9,10,2328,30,11,12,14,1618,21,22].…”

“…Similarly, Collins et al [19] compared the soil microbial community of field sites invaded by Artemisia rothrockii to non-invaded sites. The study by Wehr et al [20] focused on the effects of feral pig ( Sus scrofa ) invasion on soil microbiome comparing invaded areas to those where pigs were removed over a ~25 year chronosequence. Finally, the only study performed in an aquatic environment [22] compared water samples collected in lake areas invaded by the exotic mussel Dreissena bugensis to non-invaded sites.…”

“…Nonnative feral pigs (Sus scrofa) alter ecosystem processes and biodiversity throughout temperate and tropical ecosystems worldwide (Anderson and Stone 1993;Campbell and Long 2009;Wehr et al 2018), and their activity has been shown to affect soils (Bueno et al 2013;Long et al 2017;Singer et al 1984;Wehr et al 2019), plant communities (Cole and Litton 2014;Drake and Pratt 2001;Setter et al 2002), animal abundance and distribution (Atkinson and LaPointe 2009;Galetti et al 2015;Keuroghlian et al 2009), and watershed function (Browning et al 2008;Cuevas et al 2010;Dunkell et al 2011;Strauch et al 2016). In 2000, the management of feral pigs cost * $800 million in the United States alone (Pimentel et al 2000) and has likely increased notably since.…”
