... The concept of ecological niche was proposed and refined by Johnson and Grinnell [1,2]; it emphasizes the survival environmental requirements across the geographic distribution of species [3,4] and the interactions between communities [5]. As research progressed, the ecological niche gradually developed from a functional definition to a geometric one of the environmental capacity or ecological space occupied by a species [6]. ...

... In general, we postulated that the impact of A. mellifera on the organization of pollination networks should be positively correlated with its interactive role within such networks. This is because Cruz et al. [37] recently showed that A. mellifera has a highly interactive role in global pollination networks. However, this role varies geographically and is shaped by environmental (e.g., temperature and precipitation) and anthropogenic factors (e.g., disturbance). ...

... The impact of humans on plant communities has been documented in the scientific literature [21][22][23]. According to Falcão et al. [21], human impacts, such as land use and habitat disturbance, can affect species composition and drive plant invasiveness. ...

... PBLM thus remains the method frequently used in empirical studies (e.g. Xing et al. 2020;Corro et al. 2021). ...

... These systems are influenced by and count on interactions developed in the rhizosphere at the interface between root and soil that is under the direct influence of root exudates. This is also a zone of intense microbial activity, concentration, and diversity [10][11][12][13][14][15][16][17]. ...

... This is caused by increased wave breaking as a result of eroded sand that nourishes the foreshore bathymetry during storm action. In contrast, higher elevated dunes form a barrier to potentially shield the adjacent hinterland from elevated water level and flooding (Keijsers et al., 2015;Maximiliano-Cordova et al., 2021;Van IJzendoorn et al., 2021;Figlus, 2022;Miocic et al., 2022). Furthermore, coastal dunes show a natural capacity for self-repair and post-storm recovery under favorable conditions (Gracia et al., 2018). ...

... The substantial contribution of belowground herbivory to shaping ecosystem structure and functions is widely appreciated (Blossey and Hunt-Joshi, 2003;Johnson and Murray, 2008). Nevertheless, the levels of root herbivory in natural ecosystems remain practically undetermined (Hunter, 2008), in contrast to the thousands of published estimates of leaf area losses to insects (Turcotte et al., 2014;Kozlov et al., 2015;Mendes et al., 2021). Most importantly, nothing is apparently known regarding the geographic and/or climatic variations in belowground herbivory, as we have been unable to identify any study addressing root losses to insects along latitudinal gradients (Zvereva and Kozlov, 2021). ...

... We sampled branches from the outer part of the crown of all species; for that, we used a slingshot-like apparatus to throw a rope in the selected branch and then bring it down for sampling. We collected the first 50 leaves from the base to the apex of each branch (according to the standardized protocol of Mendes et al., 2021). Leaves were taken to the laboratory, scanned and had their margins or limb completed to account for leaf area loss to herbivores using the software GIMP. ...

... Earlier research determined that there are considerable potential suitable areas for the species with edible fruits such as S. costaricensis, S. ocamponis and S. undatus. Additionally, they may extend their ranges depending on future scenarios of climate change (Sosa et al. 2020). Our field work, however, identified species with very restricted distributions that have not yet been studied and occupy coastal and seasonally tropical dry forests. ...

... Such generalists serve as keystone species for the persistence of the network (Vanparys et al., 2008, Pasquaretta et al., 2017, Dalsgaard et al., 2021. These generalist species contribute the most to nestedness and serve as network hubs, module hubs and connectors in the network, and tend to be the most abundant in the community (Watts et al., 2016, Neves et al., 2021. Native Apis cerana and alien A. mellifera served as super-generalist pollinators in the network and thus have a high contribution to the network. ...
