“…Environmental gradients over large scales are expected to influence community assembly (Willig et al ., 2011, Cerini et al ., 2020b), given the high variation in abiotic features that can occur at regional scales and how such features shape the lives of organisms. The EMS framework is a useful tool to assess multiple competing hypotheses on species distribution structure (i.e., nestedness, checkerboardness, turnover, Leibold & Mikkelson, 2002; Presley & Willig, 2010) and to understand the role of abiotic gradients in shaping the metacommunity structure (Dallas et al ., 2016; He et al ., 2020).…”

“…Notably, none of the several analyses highlighted checkerboard patterns of metacommunities. Since the region studied is relatively northerly, this pattern could be anticipated because Odonata community checkerboardness follows the latitudinal gradient, with low likelihood of species segregation occurring in high‐latitude communities, whereas the occurrence of checkerboard structure increases towards low latitudes (Cerini et al ., 2020b).…”

“…In addition, we hypothesise Zygoptera are more likely to show a Clementsian structure than Anisoptera because of their lower dispersal capacity (Bried & Siepielski, 2018; Alves‐Martins et al ., 2019). On the other hand, we do not expect to find checkerboard patterns because, at high latitudes, communities show a low likelihood of species segregation (Cerini et al ., 2020b) probably due to higher importance of abiotic filtering on community structure in respect to species interactions. Anyway, since British Columbia spans a wide range of latitude and climate, the overall metacommunity structural patterns possibly determined by the environmental variables (i.e., nested rather than Clementsian or Gleasonian) are not easy to predict.…”

“…Among insects, Odonata have proved to be highly responsive to global changes (Hassall & Thompson, 2008;Ott, 2010;Ott & Samways, 2010;Cerini et al, 2020a), thus potentially representing a good model to be studied, especially at a large scale. Indeed, Odonata have widespread distribution all over the latitudinal gradient (Paulson, 2009(Paulson, , 2011, and high dispersion capacity (Corbet, 2004), and there are many available datasets on species occurrence both from scientific and amateur sources (Abbott, 2006(Abbott, -2020Cerini et al, 2020b).…”

The metacommunity concept, defined as a set of local communities connected by species dispersal, provides deep understanding of large‐scale ecological processes. The elements of the metacommunity structure (EMS) framework use occurrence data to differentiate among different patterns (i.e., checkerboard, nestedness, species turnover). Metacommunities of tropical Odonata show species turnover following latitude and temperature gradients but there are no such large‐scale studies for other regions. We performed EMS analysis with data for the Odonata of British Columbia, Canada, testing the role of five environmental variables (temperature, latitude, altitude, precipitation, landcover typology) in structuring the metacommunities and their turnover. The suborder Anisoptera drives the general pattern, with the communities showing a Clementsian‐type response (groups of species that replace each other along the environmental gradients) following temperature and latitude ordering. The Clementsian pattern determined by site temperatures reflects the turnover from a group of cold‐adapted species to one of warm‐adapted species, separated by many species with more generalised temperature requirements. Similarly, the Clementsian pattern associated with the latitude gradient indicates the substitution of a low‐latitude group in the south with a high‐latitude group in the north. The sites ordered by landcover did not show significant coherence and turnover. In a macro‐scale framework, Odonata species assemblages seem to be sensitive to the climatic and geographic variables of local sites (i.e., temperature and latitude), regardless of the surrounding habitat typology. The role of such variables in shaping the assembly of Odonata communities should be considered in large‐scale management and conservation projects.

“…First, Odonata are among the most well‐known insects in terms of biology, ecology, and distribution, thanks to years of scientific research (Corbet, 1999) and amateur collections and observations that contributed to build large datasets on species detailed distribution (e.g., “OdonataCentral,” Abbott, 2006–2022). Second, various studies have suggested that, in addition to habitat preference, interspecific interactions play a fundamental role in shaping Odonata communities and metacommunities (Cerini et al, 2019, 2020; Renner et al, 2019; Suutari et al, 2004). The data represent an updated and georeferenced version of the dataset from Blust and Pfeiffer (2015), a publication which summarized more than 80 years of Odonata collection activities (both scientific and amateur) in the state of Vermont.…”

The probability of occurrence of a given species in a target locality and assemblage is conditioned not only by environmental/climatic variables but also by the presence of other species (i.e., species co‐occurrence). This framework, already complex in nature, becomes even more complicated if one considers the functional traits of species that, in turn, might influence the structure of metacommunities in various ways. Depending on the ecological and environmental setting, functional similarity (i.e., convergence in morphological and ecological traits) between species might either reduce their co‐occurrence due to high niche overlap driving negative interactions or promote it if the similar traits are associated with local habitat suitability. Similarly, functional divergence might either promote species co‐occurrence by limiting negative interactions through niche separation or reduce it through trait mediated environmental filtering. Therefore, discriminating between these alternative scenarios—predicting whether two species will tend to co‐occur or not based on their traits—is extremely challenging. Here, we develop a novel protocol to tackle the challenge, and we demonstrate its effectiveness by showing that ecological species traits can predict species co‐occurrence in a large dataset of North American Odonata. To this end, we first used the Hierarchical Modeling of Species Communities framework to quantify the pairwise species co‐occurrence after controlling for environmental and climatic factors. Then, we used machine learning to generate models which proved capable of predict accurately the observed co‐occurrence patterns from species functional traits. Our approach offers a generalizable analytical framework with the potential to clarify long‐standing ecological questions.
