“…Accordingly, our results provide evidence supporting the hypothesis that both dispersal mechanisms and niche processes have collectively contributed to the turnover patterns of small mammals in the MSC. Furthermore, our findings also suggest that, due to a greater propensity for isolation caused by geographical barriers, dispersal mechanisms may exert a more pronounced influence on the community assembly of insectivores ( Wen et al, 2022b ).…”

“…Non-volant small mammals (hereafter “small mammals”) constitute excellent model species for studying community assembly and compositional turnover due to their relatively high species diversity, low dispersal ability, and narrow niche breadth, which facilitate community dissimilarity. As the two major small mammal taxa, glires (Rodentia and Lagomorpha) and insectivores (Eulipotyphla) differ substantially in body size, metabolic rate, diet, and habitat requirements ( Gliwicz & Taylor, 2002 ; Wen et al, 2022b ). Although both taxa are species-rich, glires exhibit enhanced dispersal capabilities compared to insectivores due to their larger body sizes.…”

“…In the current study, zeta diversity patterns of glires and insectivores were also compared. These two mammalian groups are characterized by different dispersal abilities and functional traits, including body size, diet, and habitat requirements ( Gliwicz & Taylor, 2002 ; Wen et al, 2022b ). Our results were consistent with the dispersal ability hypothesis, with the insectivores exhibiting a higher species turnover than glires, as well as complete species replacement at higher zeta orders (beyond ζ 15 ) and greater susceptibility to changes in distance between sites ( Figure 1H , I).…”

“…Second, communities can display non-directional change due to variable effects of dispersal limitation or biotic interactions on species range shifts. Dispersal limitation may limit the migration of species, leading to elevational distributions that are decoupled from preferred climate (Wen et al 2022). Likewise, elevational changes in the strength of local biotic interactions such as competition can result in downslope, upslope, or no change in species ranges (HilleRisLambers et al 2013, Alexander et al 2015).…”

Pervasive but lagged responses in the composition of small mammal communities to a century of climate change

Climate change has widespread effects on the distribution, abundance, and behavior of species around the world, leading to the reshuffling of ecological communities. However, it remains unclear whether individual species' range shifts scale up to result in communities whose rate of change lag, lead, or track the rate of climate change. We capitalized on a century-old data set originally collected by Joseph Grinnell and his students, plus modern resurveys, to measure long-term compositional responses of small mammal communities to climate change in historical and modern eras across three regions in the Sierra Nevada of California (Lassen, Yosemite, and Sequoia and Kings Canyon National Parks). Across this period, mean annual temperature in each region increased and mean annual precipitation decreased. We tested whether small mammal communities have shifted their composition in favor of species more adapted to hot and dry conditions, processes known as thermophilization and mesophilization respectively. We found positive thermophilization rates (communities composed of more warm-adapted species) in all three regions and negative mesophilization rates (communities composed of dry-adapted species) in one of the three regions. Importantly, thermophilization and mesophilization rates lagged behind corresponding rates of climate change on average by 0.90-1.2 °C and 26.5-111.0 mm, but the magnitude of lags was unrelated to region, amount of climate change, or their interaction. Previous work demonstrated high intraspecific variability in range shifts across the three regions in our study. Our results suggest that the net effects of climate change will be directional at the scale of the ecological community, despite variability in individual species responses to environmental change and the varied mechanisms that govern them. Communities, like many individual species, may already be out of equilibrium with ambient climate.

“…Recently, an increasingly large number of studies have explored “assemblage rules” in multiple taxa and systems. However, so far, there are no generalizable conclusions on the relationship between ecological process and biological community assembly (HilleRisLambers et al, 2012; Munkemuller et al, 2020; Wen et al, 2022). To better understand the ecological processes of community assembly, it is essential to consider the integrated effects of the spatial, environmental, and phylogenetic scales of the study system, as well as historical factors (Munkemuller et al, 2020).…”

Secondary and plantation forests are the main alternative forests remaining after the deforestation of primary forests. Understanding the conservation value of secondary and plantation forests is important for biological conservation. To explore the impact of forest conversion on biodiversity, we compared multiple diversity metrics (taxonomic, phylogenetic, and functional diversity) and community structure of small mammals in the primary, secondary, and plantation forests in Mt. Liangshan, Sichuan Province, China. Three field surveys were conducted in each of the three forest types to characterize local small mammal assemblages from 2017 to 2020. We found that the taxonomic, phylogenetic, and functional diversity of small mammals in the three forest types were similar at the landscape scale, while all diversity metrics were lowest in the plantation forest and highest in the primary forests at the site scale. The community structure analysis showed that habitat filtering was the dominant process driving the assembly of small mammal communities across the three forest types, and there was no statistically significant difference in small mammal community structure among the three forest types. Our results indicated that secondary and plantation forests in the nature reserves, adjacent to the primary forest and exposed to little human disturbance, also can provide important habitats for small mammals.
