“…The imagos (adult stage) of different species feed on sap, leaves, flowers, fruits, bark and fungi (Monné & Bezark, 2015). Due to their saproxilophagous behavior, it has been suggested that some species of this family have specific relationships with plant taxa, and thus, the moment of emergence of the imagos could be determined by the phenology of the host plants (e.g., optimizing the availability of oviposition sites, Vargas-Cardoso et al, 2018). In this way, the seasonal patterns of the emergence of Cerambycidae imagos could reflect an optimal time for their reproduction (Keszthelyi, 2015; Monné & Bezark, 2015).…”

Global climate change is expected to affect temperature and precipitation patterns worldwide, which in turn is likely to affect insect phenology, distribution and diversity. To improve our understanding of such processes, it is important to understand how insects may respond to changes in seasonality, and how these affect their activity, patterns of distribution and species richness. The tropical dry forest (TDF) is a highly seasonal ecosystem, for which two seasons are commonly described (rainy and dry) and there is a lack of information on the combined effect of both precipitation and temperature on the insect communities. In order to evaluate the seasonal patterns in the community of Cerambycidae in a TDF, historical climatic variables were obtained, and an annual sampling of the family was carried out, using three collection techniques. We found that the Cerambycidae family showed a more complex response to climate, than simply the rainy and dry season of the year. The relationship between diversity and composition of cerambycids with changes in temperature and precipitation showed four seasonal communities which were synchronized with phenological processes of the TDF. Climate change could reduce biodiversity, causing seasonal patterns to lose complexity, either because the climatic characteristics of a season disappear and/or because the duration of a season expands, these changes will modify the ecological processes of the TDF, since they would generate changes in the flora and fauna associated with the different seasons.

“…To record interactions between the saproxylophagous beetles and their host tree species, a field experiment was conducted. A total of 65 host tree species were selected based on previous studies of cerambycid specificity [47]. The selected individuals were of diameter at breast height (DBH) � 2 cm, and height � 2 m. Rearing of cerambycid larvae was chosen as the most suitable method for determination of the preferences of this group for their host trees [20].…”

“…The indices related to the organization of the interactions (number of interactions and effective partners) explained the greater variation in the ordination (PC 1). It is possible that this pattern is due to generalist and abundant species such as E. comus and Lagocheirus obsoletus obsoletus [47,80], which were the most important in terms of a number of interactions. Our hypothesis was partially confirmed, since the rest of the variation in the data (PC 2) was explained by the index of species-level specialization and the body size of the beetles in the canopy treatments (Rc, Dc).…”

Despite its high ecological importance, the commensal interactions at community level are poorly studied. In tropical dry forests (TDF) there is a great diversity of species adapted to the high seasonality that characterizes them; however, little is known regarding how the spatial and temporal availability of resources generates changes in the pattern of commensal interactions. We experimentally studied changes in the diversity, composition, and pattern of interactions in spatio-temporal associations between the saproxylophagous beetles and their host trees in a TDF in Morelos, Mexico. A total of 65 host tree species were selected, from which 16 wood sections were obtained per species. These sections were exposed in the field to allow oviposition by the cerambycids under four different (spatio-temporal) treatments. We analyzed the network structure and generated indices at species level (i.e., specialization, species strength, and effective partners) and those related to physical characteristics of the wood (hardness and degradation rate) and the cerambycids (body size). In total, 1,323 individuals of 57 species of cerambycids emerged. Our results showed that, independently of the space and time, the network presented a nested and modular structure, with a high specialization degree and a high turnover of cerambycid species and their interactions. In general, we found that the cerambycids are mostly associated with softwood species with a lower decomposition rate of wood, as well as with the most abundant host species. The commensalistic interactions between the cerambycids and their host trees are highly specialized but are not spatio-temporally static. The high turnover in the interactions is caused by the emergence patterns of cerambycids, which seem to restrict their use to certain species. The knowledge of the spatio-temporal variation in Cerambycidae-host tree interactions allows us to predict how environmental and structural changes in the habitat can modify the species ensemble, and therefore its interactions.

The climatic seasonality of the TDF determines the variation in the spatial and temporal availability of the resources (e.g., food and water) and thus generates changes in the abundance, richness, composition, and interactions of the species [4,5]. Part of the biota of the TDF can survive the drought because they present resting cycles below ground (e.g., hemicryptophyte and cryptophyte plants), or remain active in chambers that provide them with suitable conditions to continue growth, such as in the case of the sapro...
