“…However, differently of the Tetrapediini parasites and as observed in this study, Coelioxys exhibited a less specialized behavior, parasitizing nests of others bee groups, as the species of the genus Centris. This association with nests of the oil-collecting bees has also been reported by other authors such as Morato et al (1999), Aguiar and Martins (2002), Gazola andGarófalo (2009), Araujo et al (2018), Oliveira and Gonçalves (2017), Rocha-Filho et al (2017) and Araujo et al (2018).…”

“…Although the sampling effort, years and phytophysiognomy were different, the communities of SCF and EEC were structured by similar groups of natural enemies and host bees. Likewise, other authors reported similar composition in distinct Brazilian areas (Aguiar & Martins, 2002;Gazola & Garófalo, 2009;Mesquita & Augusto, 2011;Oliveira & Gonçalves, 2017;Rocha-Filho et al, 2017;Araújo et al, 2018), which evidences a closed relationship between these parasites species and their host bees. Evolutionary history and phylogenetic diversity are factors that strongly influence these ecological interactions (Michener, 2007;Staab et al, 2016;Andreazzi et al, 2017).…”

Interaction Network and Niche Analysis of Natural Enemy Communities and their Host Bees (Hymenoptera: Apoidea) in fragments of Cerrado and Atlantic Forest

2018

Natural enemies are important components of solitary bee communities that nest in preexisting cavities because they act as a relevant mortality factor and can regulate population growth. Despite this, the natural enemy-host interaction remains poorly investigated. This research aimed to determine the composition of the community, the structure of the interaction network, and niche overlap and breadth of natural enemy species in areas of Cerrado (Brazilian savanna) and Semideciduous seasonal forest (Atlantic Forest) in the state of São Paulo, Brazil. Trap-nests made of black cardboard and bamboo canes were provided in the field and inspected monthly in each area, from August 2001 to July 2003 at Cerrado and from June 2006 to May 2008 at the Semideciduous seasonal forest. A modular structure in the interaction network was observed for both areas with the populations of natural enemies showing high degrees of specialization. This structure confers higher stability against disturbances than less specialized webs since these adversities must spread more slowly through the network. The niche analysis showed low degrees of overlap for both, trophic and temporal, among the natural enemy populations.

“…Ilhabela, Boraceia, and Neblinas had species richness higher or similar than other trap-nests studies in Atlantic Forest fragments of Semideciduous vegetation which reached a maximum of 12 species (Garófalo, 2000;2008;Gazola & Garófalo, 2009;Oliveira & Gonçalves, 2017), forest urban remnants seven species (Alves-dos-Santos, 2003;Loyola & Martins, 2006), and seven species in Araucaria Forest (Buschini, 2006). However, it was lower when compared to studies performed in other biomes, such as 25 species in Cerrado (Camillo et al, 1995) and 14 species in Amazon (Morato & Campos, 2000).…”

“…Cantareira had lower number of species than aforementioned studies. However, as argued by Oliveira and Gonçalves (2017) comparisons between species richness obtained with trap-nests from different studies may be problematic because of the differences in sampling methodology, periods, the types, and arrangement of traps in the study areas.…”

“…In tropical countries trap-nesting bee species have been recorded in agroecosystems and forest fragments (Camillo et al, 1995;Morato & Campos, 2000;Viana et al, 2001;Klein et al, 2002;Alves-dos-Santos, 2003;Thiele, 2005;Buschini, 2006;Tylianakis et al, 2005;Klein et al, 2006;Pereira-Peixoto et al, 2014;Stangler et al, 2016). In Atlantic Forest, studies on the diversity of trap-nesting bee species and nesting biology were carried out mainly in Semideciduous vegetation (Garófalo, 2000;2008;Gazola & Garófalo, 2009;Rocha-Filho & Garófalo, 2015;Oliveira & Gonçalves, 2017) or forest urban remnants (Alves-dos-Santos, 2003;Loyola & Martins, 2006). Therefore, the knowledge about trap-nesting bees from the Ombrophilous Dense vegetation in the Atlantic Forest still is scarce (Menezes et al, 2012).…”

Trap-nesting Bees Communities from Protected Areas of Atlantic Forest, Southeastern Brazil

The solitary bees that use preexisting cavities can be captured in trap-nests allowing to collect data on nesting biology and associated organisms. This man-made trap-nest facilitates the understanding of environmental components and landscape composition in the fauna of solitary bees. Here, we aimed to increase the knowledge about trap-nesting bee species from four protected areas Atlantic Forest in southeastern Brazil and to test how abiotic local environmental components (temperature and rainfall) and forest cover affects the trap-nesting bee fauna. We recorded occupants from 847 nests founded by 17 bee species and seven cleptoparasite bees, associated to their host, summing 24 bee species sampled. The family with highest species richness was Megachilidae, and the species with the largest number of founded nests was Tetrapedia diversipes Klug (Apidae). Diptera, coleoptera, and hymenoptera parasitized 15.2% of the founded nests. The period of highest nest occupation occurred between November and February, which correspond to the warmest and most humid months in the region. We found significant positive correlation between the number of nests and monthly accumulated rainfall. We verified that Boraceia and Ilhabela have the best status conservation based on native forest cover and we sampled the highest diversity of species in these areas. We improved the knowledge on trap-nesting bees communities from Atlantic Forest on new species sampled in this biome with their nesting biology and highlighted that rainfall influences positively the nest founding throughout the year and native forest cover influences diversity of species.

Multi-trophic communities re-establish with canopy cover and microclimate in a subtropical forest biodiversity experiment

et al. 2021

Plant diversity affects multi-trophic communities, but in young regrowth forests, where forest insects are in the process of re-establishment, other biotic and also abiotic factors might be more important. We studied cavity-nesting bees, wasps and their natural enemies along an experimental tree diversity gradient in subtropical South-East China. We compared insect communities of experimental young forests with communities of established natural forests nearby the experiment and tested for direct and indirect effects of tree diversity, tree basal area (a proxy of tree biomass), canopy cover and microclimate on bee and wasp community composition, abundance and species richness. Finally, we tested if the trophic levels of bees, herbivore-hunting wasps, spider-hunting wasps and their natural enemies respond similarly. Forest bee and wasp community composition re-established towards communities of the natural forest with increasing tree biomass and canopy cover. These factors directly and indirectly, via microclimatic conditions, increased the abundance of bees, wasps and their natural enemies. While bee and wasp species richness increased with abundance and both were not related to tree diversity, abundance increased directly with canopy cover, mediated by tree biomass. Abundance of natural enemies increased with host (bee and wasp) abundance irrespective of their trophic position. In conclusion, although maximizing tree diversity is an important goal of reforestation and forest conservation, rapid closure of canopies is also important for re-establishing communities of forest bees, wasps and their natural enemies.
