“…Both droughts had obvious negative effects on plant growth in both natural and agricultural ecosystems, and undoubtedly contributed to lower foraging success by bees. For instance, in 2012, small carpenter bees ( Ceratina calcarata Robertson) foraged less efficiently and produced fewer broods than in 2013, when rainfall was normal (Lewis & Richards, ). Since lack of food in 1 year can result in both immediate and delayed demographic effects on bee populations (Crone, ), we surmise that the 2007 drought might have contributed to the low abundance and diversity of bees in 2008, while the drought of 2012 likely led to low abundance in that year and in 2013.…”

Abstract. 1. The effects of habitat restoration are usually studied using crosssectional comparisons of species assemblages among sites of various ages or disturbance levels. Longitudinal studies, however, are necessary for detecting longterm responses to habitat restoration and for understanding annual demographic variation.2. To investigate the time course of bee community restoration in sites previously made uninhabitable by anthropogenic disturbance, we studied a former landfill site for 10 years from initial revegetation in 2003 until 2013, comparing two restored sites with three nearby, undisturbed control sites. We used permutational multivariate analysis of variance and generalised additive mixed models to investigate how bee abundance and species richness varied over time (years), between seasons and between restoration levels.3. Landfill restoration and the creation of foraging and nesting habitat resulted in rapid and persistent occupation by bees, suggesting that efforts to restore bee communities can be successful when a source of colonists exists nearby.4. Based on earlier studies, we predicted that in restored sites there would be an initial rapid increase in bee abundance and species richness, followed by a decline to a stable intermediate level. This prediction was supported as bee abundance and species richness in restored sites increased until 2006/2007 and subsequently declined.5. In control sites, there were significant declines in abundance and species richness over time, despite a lack of anthropogenic disturbance. Possible contributors are changing weather patterns, especially severe droughts; plant community succession resulting in loss of bare ground for nesting sites; and increasing suburbanisation of the surrounding landscape.

“…In most Ceratina species that have been studied in-depth behaviourally, offspring are guarded by mothers until adulthood (Rehan & Richards, 2010b;Mikát et al, 2016). Benefits of prolonged maternal care include increased offspring survival (Mikát et al, 2016) and feeding of adult offspring by the mother (Lewis & Richards, 2017;Mikát et al, 2017). To date, facultative nest abandonment has only been described in the closely related species C. chalybea (Mikát et al, 2016).…”

“…Previous work has shown that mothers in some Ceratina species continue to feed their adult offspring after reaching adulthood (Sakagami & Maeta, 1977;Lewis & Richards, 2017;Mikát et al, 2017) and that dwarf eldest daughters can perform sibling provisioning in cases of maternal death (Mikát et al, 2017). Specific allocation of food to brood cells by mothers is linked to the provisioning of adult siblings by a sister.…”

“…Mothers usually guard offspring after the completion of brood cell provisioning until offspring reach adulthood (Rehan & Richards, 2010b;Mikát et al, 2016). When offspring develop into adults, mothers feed the adult juveniles pollen and nectar (Sakagami & Maeta, 1977;Lewis & Richards, 2017 ;Mikát et al, 2017) and usually die while feeding the mature offspring (Mikát et al, 2017). Therefore there is no possibility for new reproduction events.…”

“…Therefore there is no possibility for new reproduction events. In some species it has been shown that, if the mother dies, a sister of the young adults can perform provisioning (Lewis & Richards, 2017;Mikát et al, 2017). This helper sister is usually produced in the first brood cell position and is smaller than other females produced in the same nest (Lawson et al, 2016;Mikát et al, 2017).…”

1. Maternal investment can be influenced by several factors, especially maternal quality and possibilities for future reproduction. Mass provisioning Hymenoptera are an excellent group for measuring maternal investment because mothers distribute food sources to each brood cell for each offspring separately. Generally in aculeate Hymenoptera, larger females produce larger offspring and invest more in female offspring than in male offspring. 2. This study investigated patterns of maternal investment in Ceratina chalcites, which has an uncommon type of sexual size dimorphism in Hymenoptera: on average, males are heavier than females. It was found that larger females produce a significantly higher proportion of male offspring, as males are the costlier sex in this species. 3. Facultative nest guarding by females was observed. Females can guard offspring until adulthood, as is typical for bees of genus Ceratina (34.43% of nests); however, in the majority of cases (65.56% of nests), females plug and abandon the nest. Significant differences were found in the amount of investment between guarded and unguarded nests. Guarded nests had a greater number of provisioned brood cells and a higher proportion of male offspring. It is suggested that mothers have two facultative strategies – either she makes a large investment in the offspring of one nest or she abandons the first nest and carries out a second nesting elsewhere.
