“…The black Portuguese millipede, Ommatoiulus moreletii, had the most articles (27), probably due to its status as a nuisance pest in urban areas. The European earwig, Forficula auricularia, is an introduced species that is considered to be the predominant earwig pest in Australian broad-acre systems (Bower 1993;Quarrell et al 2018), causing damage to several crop types including canola, cereals and some legumes; the study of Hill et al (2019) is a recent modelling study on this species. Pest slaters (Isopoda), such as Porcellio scaber, had fewer articles (seven).…”

“…More recently, studies have been undertaken to understand the feeding behaviours of some of these pests. There is increasing interest locally, with three articles published in Australia since 2014 (Quarrell et al 2017;Hill et al 2019;Quarrell et al 2018). In contrast, damage caused by O. moreletii was limited to lupin, lucerne and canola.…”

“…Several species of exotic and native earwigs (Dermaptera) present in Australia, with diverse diets, appear to have the potential to be both natural enemies and pests. The European earwig, Forficula auricularia, is an introduced species that is considered to be the predominant earwig pest in Australian broad-acre systems (Bower 1993;Quarrell et al 2018), causing damage to several crop types including canola, cereals and some legumes; the study of Hill et al (2019) is a recent modelling study on this species. Despite this, we found only four articles for this species ( Fig.…”

“…F. auricularia seems to be increasing in status as an agricultural crop pest worldwide (Sakai 1987;Quarrell et al 2018). There is increasing interest locally, with three articles published in Australia since 2014 (Quarrell et al 2017;Hill et al 2019;Quarrell et al 2018). Earwigs are also described as a beneficial natural enemy in some agricultural systems (see section below); however, factors that lead to them feeding on crop seedlings rather than invertebrates or stubble are unknown.…”

Identifying critical research gaps that limit control options for invertebrate pests in Australian grain production systems

Integrated Pest Management (IPM) is often described as a knowledge-intensive approach to invertebrate pest management, requiring information on the biology, ecology and phenology of a pest combined with an understanding of the interactions between crop growth and pests and between pests and their natural enemies. We conducted a systematic quantitative literature review to summarise what is known about pest and natural enemy species common to Australian grain production systems, based on 1513 published and unpublished research studies. Drawing on this information, we address three issues: what are the knowledge gaps in relation to grain pests and their natural enemies, do these knowledge gaps limit the development of an IPM package for grain growers in Australia and what further ecological or biological information might growers require to enhance the use of IPM approaches for managing pests? The main gaps identified include a lack of understanding around specific factors that lead to pest outbreaks or factors that could be useful for predicting when and where pest outbreaks will occur in the future. Monitoring techniques for many pests are not well developed, and therefore, it is difficult to link the density recorded in a field with crop damage and yield loss and to develop economic thresholds that can be linked with intervention decisions. For most natural enemies, the impact in terms of reduction in pest numbers has not been quantified, with very few studies including both pests and natural enemies together. There is large variability in the level of control provided by natural enemies between years and regions, and the factors leading to this variability are not well understood. Finally, the lack of taxonomic resolution for individual species within groups is identified as a critical knowledge gap. We suggest that a more comprehensive fundamental knowledge base is required across the invertebrate community in grain systems aimed at reducing insect pest outbreaks, combined with a greater depth of understanding in monitoring strategies for pests that contribute to pesticide-use decisions.

“…For example, exotic pet introduction depends on their release into the environment; thus, propagule pressure for these animals should be higher in large urban centres and their surroundings, and closer to residences [ 22 , 23 ]. As a result, the inclusion of human activity measures in the SDM allows combining the probability of introduction or release (and accessibility) with climatic suitability of habitat [ 24 , 25 ] to provide more realistic scenarios.…”

Pet distribution modelling: Untangling the invasive potential of Trachemys dorbigni (Emydidae) in the Americas

Human activities have been changing the global biogeographic patterns by the introductions of invasive species. For reptiles, the invasion rate increase of non-native species is remarkably related to the pet trade, especially for freshwater turtles. Here we estimated the invasive potential of the South American turtle Trachemys dorbigni in the Americas using a combination of climatic and human activity variables. We built species distribution models based on data from the native and invasive ranges, using the ensemble model from five different algorithms (GAM, MAXENT, BRT, RF and GBM). We compared the two models’ performance and predictions, one calibrated with only climatic variables (climate-driven), and the second also included a descriptive variable of human activity (climate plus human-driven). Suitable areas for T. dorbigni covered occurrence areas of its congeners and highly diversified ecoregions, such as the eastern USA, the islands of Central America, and the south eastern and eastern Brazilian coast. Our results indicate that human activities allow T. dorbigni to establish populations outside of its original climatic niche. Including human activity variables proved fundamental to refining the results to identify more susceptible areas to invasion and to allow the efficient targeting of prevention measures. Finally, we suggested a set of actions to prevent T. dorbigni becoming a highly impacting species in the areas identified as more prone to its invasion.

Variations in seasonal (not mean) temperatures drive rapid adaptations to novel environments at a continent scale

The recent development of human societies has led to major, rapid, and often inexorable changes in the environment of most animal species. Over the last decades, a growing number of studies formulated predictions on the modalities of animal adaptation to novel or changing environments, questioning how and at what speed animals should adapt to such changes, discussing the levels of risks imposed by changes in the mean and/or variance of temperatures on animal performance, and exploring the underlying roles of phenotypic plasticity and genetic inheritance. These fundamental predictions, however, remain poorly tested using field data. Here, we tested these predictions using a unique continental‐scale data set in the European earwig Forficula auricularia L., a univoltine insect introduced in North America one century ago. We conducted a common garden experiment, in which we measured 13 life‐history traits in 4,158 field‐sampled earwigs originating from 19 populations across North America. Our results first demonstrate that 10 of the 13 measured life‐history traits are associated with two sets of variations in seasonal temperatures, that is, winter–summer and autumn–spring. We found, however, no association with the overall mean monthly temperatures of the invaded locations. Furthermore, our use of a common garden setup reveals that the observed patterns of variation in earwigs’ life‐history traits are not mere plastic responses to their current environment, but are either due to their genetic background and/or to the environmental conditions they experienced during early life development. Overall, these findings provide continent‐scale support to the claims that adaptation to thermal changes can occur quickly (in less than 100 generations), even in insects with long life cycles, and emphasize the importance of variation in seasonal temperature over mean population temperatures in climate adaptation.
