“…Excavation techniques have been improved and used since then to study nest architecture and reproductive output of many ground‐nesting bees. Unfortunately, this procedure is both destructive and extremely meticulous, given the challenge of tracking tunnels in the midst of falling debris (Marinho et al ., 2018). If internal nest architecture is not the focus, targeted emergence traps can be useful.…”

1. About 3/4 of all wild bee species nest in the soil and spend much of their life cycle underground. These insects require suitable environmental conditions for nest construction and for the development and survival of their offspring. However, there is little quantitative information on the nesting habitat requirements and preferences of ground-nesting bees. Moreover, there are almost no data on the effects of nesting conditions on these bees' fitness. 2. Here, to better understand the factors that influence nest-site selection in ground-nesting bees, we synthesise the literature on the nesting-habitat associations of these important pollinators. We also review techniques that can be used to study the nesting preferences of ground-nesting bees. 3. Our review reveals enormous variation among bee species in their associations with such nesting-habitat attributes as soil texture, compaction, moisture, temperature, ground surface features, and proximity to conspecifics or floral resources. However, more studies-particularly experimental ones-are needed to segregate the influence of each factor on bees' choices of nesting location, since multiple factors are often correlated. It is also unclear whether nesting-habitat associations vary geographically or seasonally within species, or phylogenetically among ground-nesting bee species, partly because we lack information on nesting habitat for many species. 4. We argue that studies using established habitat-selection methods are essential to properly identify nesting-habitat preferences of ground-nesting species. Finally, more research on nesting ecology is needed (especially in agroecosystems) to determine how best to support this diverse group of bees and the vital ecosystem service they provide.

“…The nesting habits of the species were directly observed and digitally recorded. To guide the excavations and to obtain the size of tunnels was followed the methodology proposed by Marinho et al (2018) which consists in to use a flexible rubber tube marked with centimeters. We used a tube with 0.6 cm of diameter and 150 cm in length.…”

An aggregation of the oil-collecting bee Epicharis dejeanii Lepeletier was studied at Ilha das Flores, southern Brazil. Data on seasonality, types of floral resources collected, and nesting biology were registered. The nesting area occupied 120 m 2 with density of up to 8 nests/m 2. The tunnel entrances remained always open and surrounded by a tumulus. Adult activity lasted approximately 70 days. The females built the nest, provisioned food, and layed the egg in 4 days. The nest's architecture was very diverse, and they were between 40 and 140 cm in depth with one or two brood cells at the end of the tunnel. Diapause occurred in the postdefecating larval stage, and there was no cocoon. Immature stages and nest architecture are described and illustrated.

“…Mayagüez is a coastal town and in these exact coordinates, Centris decolorata specimens were also collected ( Figure 1A ). Centris decolorata nests were excavated in two Mayagüez plots following the method by Marinho et al (2018) . A total of 46 individuals were collected for this study.…”

IntroductionInterest for bee microbiota has recently been rising, alleviating the gap in knowledge in regard to drivers of solitary bee gut microbiota. However, no study has addressed the microbial acquisition routes of tropical solitary bees. For both social and solitary bees, the gut microbiota has several essential roles such as food processing and immune responses. While social bees such as honeybees maintain a constant gut microbiota by direct transmission from individuals of the same hive, solitary bees do not have direct contact between generations. They thus acquire their gut microbiota from the environment and/or the provision of their brood cell. To establish the role of life history in structuring the gut microbiota of solitary bees, we characterized the gut microbiota of Centris decolorata from a beach population in Mayagüez, Puerto Rico. Females provide the initial brood cell provision for the larvae, while males patrol the nest without any contact with it. We hypothesized that this behavior influences their gut microbiota, and that the origin of larval microbiota is from brood cell provisions.MethodsWe collected samples from adult females and males of C. decolorata (n = 10 each, n = 20), larvae (n = 4), and brood cell provisions (n = 10). For comparison purposes, we also sampled co-occurring female foragers of social Apis mellifera (n = 6). The samples were dissected, their DNA extracted, and gut microbiota sequenced using 16S rRNA genes. Pollen loads of A. mellifera and C. decolorata were analyzed and interactions between bee species and their plant resources were visualized using a pollination network.ResultsWhile we found the gut of A. mellifera contained the same phylotypes previously reported in the literature, we noted that the variability in the gut microbiota of solitary C. decolorata was significantly higher than that of social A. mellifera. Furthermore, the microbiota of adult C. decolorata mostly consisted of acetic acid bacteria whereas that of A. mellifera mostly had lactic acid bacteria. Among C. decolorata, we found significant differences in alpha and beta diversity between adults and their brood cell provisions (Shannon and Chao1 p < 0.05), due to the higher abundance of families such as Rhizobiaceae and Chitinophagaceae in the brood cells, and of Acetobacteraceae in adults. In addition, the pollination network analysis indicated that A. mellifera had a stronger interaction with Byrsonima sp. and a weaker interaction with Combretaceae while interactions between C. decolorata and its plant resources were constant with the null model.ConclusionOur data are consistent with the hypothesis that behavioral differences in brood provisioning between solitary and social bees is a factor leading to relatively high variation in the microbiota of the solitary bee.
