“…Heterogeneous landscapes offer more niches and complementary resources [78] than homogeneous landscapes and, hence, more functional groups are expected to coexist in such heterogeneous areas. In the Cantabrian Mountains, we found a positive relationship between landscape heterogeneity and functional diversity, consistent with the findings of other studies carried out in Central America [79] and Romania [80]. In mountains, the landscape is heterogeneous [37] as a result of topographic and climatic complexity, as well as traditional human intervention.…”

Knowledge on the relationships between species functional traits and environmental filters is key to understanding the mechanisms underlying the current patterns of biodiversity loss from a multi-taxa perspective. The aim of this study was to identify the main environmental factors driving the functional structure of a terrestrial vertebrate community (mammals, breeding birds, reptiles and amphibians) in a temperate mountain system (the Cantabrian Mountains; NW Spain). Based on the Spanish Inventory of Terrestrial Vertebrate Species, we selected three functional traits (feeding guild, habitat use type and daily activity) and defined, for each trait, a set of functional groups considering vertebrate species with common functional characteristics. The community functional structure was evaluated by means of two functional indexes indicative of functional redundancy (species richness within each functional group) and functional diversity. Ordinary least squares regression and conditional autoregressive models were applied to determine the response of community functional structure to environmental filters (climate, topography, land cover, physiological state of vegetation, landscape heterogeneity and human influence). The results revealed that both functional redundancy and diversity of terrestrial vertebrates were non-randomly distributed across space; rather, they were driven by environmental filters. Climate, topography and human influence were the best predictors of community functional structure. The influence of land cover, physiological state of vegetation and landscape heterogeneity varied among functional groups. The results of this study are useful to identify the general assembly rules of species functional traits and to illustrate the importance of environmental filters in determining functional structure of terrestrial vertebrate communities in mountain systems.

“…However, this approach has been focused only on the number of species. Therefore, to achieve a fuller understanding of the spatial patterns of biodiversity and its determinants, i.e., the environmental factors that regulate biodiversity, the spatial distribution of other facets or dimensions of biodiversity has become the subject of recent studies [5–10]. One of these dimensions is functional diversity, in which species are characterized by their functional traits, that are suspected to be relevant in their performance in specific habitats, providing a greater understanding of the links that exist between biodiversity and ecosystem functioning [8, 11–13].…”

“…However, it has recently been found that the species richness and functional diversity of mammals do not have a marked spatial congruence. Therefore, a disparity or spatial mismatch is often found in these dimensions of diversity; while species richness often correlates closely with environmental conditions, such as elevation, temperature and productivity, functional diversity depends on both environmental conditions and ecological interactions among coexisting species, such as competence [7, 8, 10, 23].…”

“…It is expected that the richness of cricetid rodents will be explained by elevation [31–33] while the functional diversity will be determined by a set of environmental factors. In addition, it has been seen that the spatial patterns of richness and functional diversity are unrelated (i.e., are spatially incongruent) in other groups of mammals with lower diversity [10], and therefore we assume that the lack of spatial congruence between these two dimensions of biodiversity will be even higher in a more diverse group, such as the cricetid rodents.…”

Spatial incongruence in the species richness and functional diversity of cricetid rodents

et al. 2019

Biodiversity is multidimensional and different mechanisms can influence different dimensions. The spatial distribution of these dimensions can help in conservation decisions through the location of complementary areas with high diversity. We analyzed congruence in spatial patterns of species richness and functional diversity of cricetid rodents in the state of Oaxaca, southern Mexico, at different scales, and environmental variables related. Potential distribution models were produced for 49 species of cricetids in Maxent and superimposed to obtain potential communities in cells of 25, 50,100, 200 and 400 km 2 . We estimated species richness (SR) and functional diversity (SES.FD) eliminating the species richness effect through null models. The patterns and spatial congruence of species richness and functional diversity are described. The relationships between the environmental variables (elevation, temperature, precipitation, net primary productivity and potential evapotranspiration) and the SR and SES.FD were explored using Generalized Linear Models (GLMs) and Generalized Additive Models (GAMs). The highest species richness was found in mountainous ecosystems while the highest functional diversity was in tropical forests, revealing a spatial incongruence among these components of biodiversity (r = -0.14, p = 0.42; Pearson correlation). The locations of the cells of low congruence varied according to spatial resolution. In univariate models, elevation was the variable that best explained species richness (R 2 = 0.77). No single variable explained the functional diversity; however, the models that included multiple environmental variables partially explained both the high and low functional diversity. The different patterns suggest that different historic, ecological and environmental processes could be responsible for the community structure of cricetid rodents in Oaxaca. These results indicate that one great challenge to be met to achieve more effective planning for biological conservation is to integrate knowledge regarding the spatial distribution of different dimensions of biodiversity.

“…However, several regional studies have used the total PD of a given site (often a grid cell) as its conservation value and thus did not consider that branches can be shared among sites. This departure from the basic framework of conservation planning based on the complementarity of sites (Margules and Pressey 2000) may originate from the community ecology framework where the total PD of a site is of interest (e.g., Gómez-Ortiz et al 2017; see the section titled Why Approaches in Community Ecology and Conservation Biology Should Be Different). Yet, in conservation biology, the purpose to maximize the protection of a region's diversity is not achieved with this method because sites with the highest total PD will most likely share branches and thus redundant information (Figure 1; Pollock et al 2017;Faith et al 2018a).…”

*AB1abstract *AB2The use of phylogenetic tools and studies has strongly increased in the last two decades especially in conservation biology and community ecology. Phylogenetic trees have been essential to understand the processes of community or network assembly, to identify centers of diversification, and to help protect Earth's evolutionary heritage. Despite two decades of research and syntheses, there are still many discussions on how phylogenetic diversity (PD) methods should be effectively applied to those fields. In particular, conservation approaches based on PD have become similar to these used in community ecology. Thus, the main benefit of using PD calculations in conservation biology may have been ignored or misinterpreted. Our goal is to discuss and provide guidelines to the use of PD in biodiversity conservation so that its benefits are not hidden or lost in the approaches employed. We also aim that benefits and uses are better recognized and more easily understood by researchers or practitioners who would like to include PD in their studies and conservation planning. *S1Introduction
