Context dependency of the density–body mass relationship in litter invertebrates along an elevational gradient

摘要: Abstract How community structure responds to environmental changes in space and time is a key concern ecology. As synthesized indicator of structure, the density–body mass (DBM) relationship reflecting body size distributions can serve as linkage between response ecological processes function. However, drivers spatial temporal shifts DBM for brown food webs remain largely unknown. This study aimed find elevational pattern litter invertebrate communities understand causes climate resource factors shaping this different spatio-temporal contexts. We identified invertebrates temperate montane forest and, first time, examined by taking account contexts integrating growing dormant seasons. Furthermore, we assessed relative roles (i.e., temperature, light, moisture) quality quantity) distribution patterns. In general, demonstrated were size-structured at all elevations seasons, which underpins DBM. patterns slopes varied seasons: season shallower with increasing elevation. Contrasting, steeper elevation season. indicating that along elevation, larger benefited more compared smaller invertebrates, The context dependent: (1) temperature was fundamental driver across benefiting invertebrates; (2) crown density only matters season, light intensity invertebrates. No impact soil moisture on detected; (3) availability C:N C:S ratios) quantity amount), mainly functioning respectively. finding would enhance predictive understanding how change may restructure ecosystems from an allometric scaling perspective global warming.
