“…We quantified functional redundancy for 51 small mammal assemblages across Eurasia compiled in Hadfield et al (2014) and partially described in Krasnov et al (2010, 2020)2020. These data were compiled from published and unpublished regional assessments of small mammals over multiple years.…”

“…The original sources did not commonly include information about the sampling design or effort (Krasnov et al 2020). While the compilation of data from multiple sources and years, and lack of information about the sampling design are not ideal, this data set has been very useful for describing biogeographic patterns of mammal parasitic interactions (Vinarski et al 2007, Krasnov et al 2010, 2020, Hadfield et al 2014, Poisot et al 2017). The small mammal assemblages included 121 mammal species (Mammalia: Rodentia and Mammalia: Soricomorpha) and spanned over 34 degrees in latitude and more than 140 degrees in longitude.…”

“…Flea surveys were conducted in each of the sampled locations (Krasnov et al 2010, 2020, Hadfield et al 2014). Fleas (Insecta: Siphonaptera) are holometabolous ectoparasites most commonly found in small to medium‐sized mammals (Medvedev and Krasnov 2006).…”

This dataset also includes small mammal interactions with parasitic fleas (Insecta: Siphonaptera).…”

Functional redundancy (FR) is commonly invoked as one of the main mechanisms underlying ecological resilience. However, little is known about the extension of FR from single to multiple functions and its variation among ecological assemblages at biogeographic scales. We studied 51 assemblages of Eurasian small mammals (Mammalia: Rodentia and Mammalia: Soricomorpha), analyzing FR across and within assemblages. We quantified FR for trait sets related to five different functions: parasitic interactions, diet, habitat preferences, body mass and diel activity. We then evaluated the relationships between FR based on different functional trait sets across and within mammal assemblages, to determine whether small mammal assemblages and their species are redundant for single or multiple trait sets and thus, whether they are complementary or fully redundant when considering multiple functions. Further, we analyzed the influence of geography, climate, plant productivity and land use on FR. We found that FR based on mammal parasitic interactions, body mass and diel activity were positively correlated, whereas FR based on mammal body mass and habitat preferences were negatively related. These relationships were consistent across and within mammal assemblages. Additionally, FR mainly varied along geographic gradients (latitude and longitude). FR based on parasitic interactions, body mass and diel activity followed similar patterns, increasing at northern latitudes, possibly as a response to environmental filtering processes. FR for diet and habitat preferences increased at easterly longitudes, which may be due to landscape homogeneity in sites across central and eastern Asia. Despite redundancy across multiple functional trait sets, Eurasian small mammal assemblages were complementary when considering all five trait sets. Our results warn against conclusions drawn from the study of FR based on traits related to a single function.

“…Current evidence suggests that parasite turnover at broad scales is mostly affected by host diversity and climate, with a minor effect of spatial distance [10][11][12][13][14]. Since many parasites release larvae and eggs into the environment, climate has an impact on parasite survival, emergence and infectivity during these stages [15,16].…”

A robust understanding of what drives parasite β-diversity is an essential step towards explaining what limits pathogens' geographical spread. We used a novel global dataset (latitude −39.8 to 61.05 and longitude −117.84 to 151.49) on helminths of anurans to investigate how the relative roles of climate, host composition and spatial distance to parasite β-diversity vary with spatial scale (global, Nearctic and Neotropical), parasite group (nematodes and trematodes) and host taxonomic subset (family). We found that spatial distance is the most important driver of parasite β-diversity at the global scale. Additionally, we showed that the relative effects of climate concerning distance increase at the regional scale when compared with the global scale and that trematodes are generally more responsive to climate than nematodes. Unlike previous studies done at the regional scale, we did not find an effect of host composition on parasite β-diversity. Our study presents a new contribution to parasite macroecological theory, evidencing spatial and taxonomic contingencies of parasite β-diversity patterns, which are related to the zoogeographical realm and host taxonomic subset, respectively. This article is part of the theme issue ‘Infectious disease macroecology: parasite diversity and dynamics across the globe’.
