“…Soil microorganisms and their primary consumers in the S″ compartment can move within the water microfilm ( via passive dispersal), but narrower windows of aqueous phases and higher viscosity may impose formidable challenges to movement in the S″ compartment (Tecon & Or, ). Nevertheless, large‐scale dispersal (from m to km) of soil microorganisms is a common phenomenon regulated mostly via rainfall and wind events and also by human‐mediated dispersal (Vos et al ., ; Thakur et al ., ). Although the dispersal ability of soil organisms will vary among different spatial compartments, it is important to note that species traits and soil structure will both impose challenges on the dispersal of soil organisms.…”

Soil is one of the most biodiverse terrestrial habitats. Yet, we lack an integrative conceptual framework for understanding the patterns and mechanisms driving soil biodiversity. One of the underlying reasons for our poor understanding of soil biodiversity patterns relates to whether key biodiversity theories (historically developed for aboveground and aquatic organisms) are applicable to patterns of soil biodiversity. Here, we present a systematic literature review to investigate whether and how key biodiversity theories (species–energy relationship, theory of island biogeography, metacommunity theory, niche theory and neutral theory) can explain observed patterns of soil biodiversity. We then discuss two spatial compartments nested within soil at which biodiversity theories can be applied to acknowledge the scale‐dependent nature of soil biodiversity.

“…For example, the number of fungal species on earth is unknown, but estimates range from 1.5 to several million, the majority of which have not yet been described (Crous et al 2015;Hawksworth and Lüking 2017). The lack of 'visibility' of microorganisms has been repeatedly provided as the reason for their absence from invasion science (Desprez-Loustau et al 2007;Sakalidis et al 2013;Wingfield et al 2017;Thakur et al 2019). Most IFPs remain undetected until visible negative impacts are observed within the recipient environment.…”

“…Despite this, these microorganisms may still affect important ecosystems functions, and likely play an important role in facilitating invasions by other taxa. There has been a growing acknowledgement of the importance of studying and understanding these invasions (see Desprez-Loustau et al 2007;Litchman 2010;Gladieux et al 2015;Crous et al 2016;Dickie et al 2017;Thakur et al 2019).…”

“…Importantly, also where, when and how invasions can be stopped or mitigated. The issue of microbial invasions has been described as one of the most pressing topics facing invasion science (Ricciardi et al 2017;Thakur et al 2019). Therefore, a greater inclusion of IFPs and microorganisms in general, is essential for the continued advancement of the field of invasion science.…”

Invasive alien species are widely recognised as significant drivers of global environmental change, with far reaching ecological and socio-economic impacts. The trend of continuous increases in first records, with no apparent sign of saturation, is consistent across all taxonomic groups. However, taxonomic biases exist in the extent to which invasion processes have been studied. Invasive forest pathogens have caused, and they continue to result in dramatic damage to natural forests and woody ecosystems, yet their impacts are substantially underrepresented in the invasion science literature. Conversely, most studies of forest pathogens have been undertaken in the absence of a connection to the frameworks developed and used to study biological invasions. We believe this is, in part, a consequence of the mechanistic approach of the discipline of forest pathology; one that has been inherited from the broader discipline of plant pathology. Rather than investigating the origins of, and the processes driving the arrival of invasive microorganisms, the focus of pathologists is generally to investigate specific interactions between hosts and pathogens, with an emphasis on controlling the resulting disease problems. In contrast, central to the field of invasion science, which finds its roots in ecology, is the development and testing of general concepts and frameworks. The lack of knowledge of microbial biodiversity and ecology, speciation and geographic origin present challenges in understanding invasive forest pathogens under existing frameworks, and there is a need to address this shortfall. Advances in molecular technologies such as gene and genome sequencing and metagenomics studies have increased the “visibility” of microorganisms. We consider whether these technologies are being adequately applied to address the gaps between forest pathology and invasion science. We also interrogate the extent to which the two fields stand to gain by becoming more closely linked.

“…However, despite these significant preventative efforts, "biological spills" keep occurring at an alarming rate and show no signs of abating (Seebens et al, 2017;Meurisse et al, 2019;Thakur et al, 2019). While prevention, early detection, and eradication are our critical frontline defenses, once breached, established, non-native, tree-killing forest PIPs often cause widespread mortality of native trees.…”

Maintenance and restoration of forest ecosystems will be key to achieving necessary carbon sequestration goals, protecting biodiversity, and supporting healthy economies and societies. Forest ecosystems are increasingly threatened by non-native forest insects and pathogens. A portion of these pests are able to overcome prevention and containment efforts and become established in naïve ecosystems. Once established these pests pose a long-term large-scale threat to forest ecosystems, which current policy and response frameworks are poorly equipped to address. We propose the creation of a federal Center for Forest Pest Control and Prevention to implement end-to-end responses to forest pest invasions using an ecologically-informed framework that fully integrates host tree resistance development and deployment.
