Recolonizing native wildlife facilitates exotic plant invasion into Singapore's rain forests: Data and R script
<p>Halting biological invasions and rewilding extirpated fauna are conservation interventions to bolster biodiversity, species interactions, and ecosystems. These actions are often considered separately and the potential for reintroduced wildlife to facilitate invasive plants has been largely overlooked. Here, we investigate the role of Singapore's recolonizing native wild pigs (<em>Sus scrofa</em>) in facilitating an invasive weed <em>Miconia crenata </em>into tropical rain forests, which are normally highly resistant to invasion. We conducted line-transect surveys in 11 Singaporean rain forests and used generalized linear mixed models to consider the contribution of pigs' soil disturbances, human forest paths, and other environmental covariates, on the density of <em>M. crenata</em>. We found that <em>M. crenata</em> was more abundant at forest edges and invasion into forest interior was facilitated by pigs, paths, and canopy gaps, but that these effects were all additive, not synergistic (i.e. not multiplicative). These<span> results highlight how modern invasions are driven by multiple disturbances as well as propagule pressure (e.g. urban birds dispersing seeds at forest edges where they establish in pig soil disturbances). </span>Singapore's extensive native forest restoration efforts may have provided plentiful edge and secondary forests that are well suited to pigs and <em>M. crenata</em>, which in turn undermine the aims of fostering later-successional native plant communities. To prevent negative externalities, we suggest that plant restoration and rewilding projects consider the potential role of wildlife in facilitating non-native plants, and couple these actions with preliminary screening of unintended consequences and continued monitoring, as well as limiting human-mediated weed invasion to minimize propagule sources.</p>

Data and R code for: Handling- or digestion-limited predator: the role of body masses and habitat complexity in predator-prey feeding interaction
<p><span>Predator functional response is a key element of feeding interactions that quantify the per capita feeding rates of predators depending on prey density, and variation in its parameters is strongly associated with interaction strength and population dynamics. We studied 18 functional responses of the marine whelk-bivalve systems across three levels of predator body size and three prey species at two habitat structures. We found that the marine whelk can be a handling-limited predator which received less attention so far. We propose that the handling-limited predator can further be categorized into two types: pursuing-limited (where maximum feeding rate could be influenced by habitat complexity) and ingesting-limited (where maximum feeding rate is impacted not by habitat complexity, but predator-prey body mass ratios and prey defense strategy). Our results show that handling time scales negatively with predator-prey body mass ratios, but there are layers of complexity nested within this trend. We first provide an underlying mechanism of this trend is the transition from handling to digestion limitation with increasing predator-prey body mass ratios. In addition to confirming known body mass ratios and habitat structure effects, our study confirms the importance of prey types. Our study reveals that simple assumptions about body masses and prey defense strategy may usefully refine estimates of feeding interactions in complex food webs.</span></p>
