“…Fragment size effects on species diversity, percentage of Centris , and parasitism rate Contrary to our expectations, fragment size had no effect on bee diversity. Previous studies in tropical systems relating bee diversity to size have revealed variable results, some showing an increase in diversity with size (Chacoff and Aizen 2005;Brosi 2009;Meneses Calvillo et al 2010) and others finding no relationships between fragment size and diversity (Brosi et al 2007b;Gazola and Garófalo 2009). This variability could be due to many factors, since little is known about the nesting behavior of bees in tropical forests.…”

-Secondary rainforest remnants might contribute to biodiversity conservation and preservation of healthy interspecific interactions with ongoing fragmentation. We studied the vertical distribution of trap-nesting bees along a fragmentation gradient of secondary forest remnants in Costa Rica. Fragment size did not affect bee abundance, diversity, and parasitism and mortality rates. However, height and edge effects influenced bee communities. Bees were more abundant in the canopy and the understory compared to an intermediate height, and bee diversity was higher in the canopy. Tree location (forest edge, intermediate distance, forest center) did not affect abundance but did affect bee diversity since most species preferred the forest interior. The cuckoo bees Aglaomelissa duckei and Coelioxys sp. 1 only partly followed their hosts' patterns, two Centris species. We conclude that an increasing amount of edge habitat will have negative consequences for bee communities and will reduce the conservation value of secondary forest fragments. fragmentation effects / parasitism rate / mortality rate / secondary forest fragments / vertical stratification

“…As Gotelli and Colwell (2010) observed, lack of independence between samples can be neglected if rarefaction curves are functions of the number of samples. Comparison of species richness with unequal sampling effort, which incorporates sample-based rarefaction curves, is often used (Calvillo et al, 2010;Banaszak-Cibicka and Żmihorski, 2012;Żmihorski et al, 2013). To estimate the true species number, we applied 2 estimators: Chao2 (Chao, 1984) and Jackknife2 (Burnham and Overton, 1979).…”

a b s t r a c t Wild bees (apiformes) were studied in 4 crop fields and 8 refuge habitats for 2 -5 years in agricultural landscapes in the pleven and plovdiv regions of Bulgaria. in total, 233 bee species were recorded. Bee forage plants visited by the honey bee and wild apiformes are listed for each refuge habitat. species composition is given for individual habitats, including fields of alfalfa (medicago sativa), oilseed rape (Brassica napus), sunflower (Helianthus annuus), and radish (raphanus sativus). species richness and dominance structure of bee communities in the 2 regions are compared, and species responsible for significant differences are identified.

“…Although ours is the first study that reports on Australian stingless bees and the effects of tropical fragmentation, it follows a number of studies from other tropical regions. In a study of tropical forest fragments in Mexico, Calvillo et al (2010) found no effect of suggest that dispersal of the species may benefit from forest fragmentation and degradation. These studies, and our own, highlight the diverse responses of stingless bee species to habitat fragmentation and also the regional differences found throughout the tropics.…”

“…Bees (Hymenoptera: Apoidea) are the most important pollinator group globally. Empirical studies on the effects of habitat fragmentation on bees are historically uncommon (Cane, 2001), and even with a rise in interest in this topic over recent years, most studies that have been conducted focus on the neotropics (e.g., Aizen & Feinsinger, 1994;Brosi, Daily, Shih, Oviedo, & Duran, 2008;Calvillo, Ramirez, Parra-Tabla, & Navarro, 2010;Ferreira et al, 2015;Powell & Powell, 1987;Tonhasca Jr, Blackmer, & Albuquerque, 2002). While these studies have had mixed results, including both negative (e.g., Aizen & Feinsinger, 1994;Calvillo et al, 2010) and neutral (e.g., Tonhasca Jr et al, 2002) effects of fragmentation on bee diversity, they all tend to show that different bee groups respond differently to fragmentation, probably as a result of distinct nesting and foraging traits among species (Brosi et al, 2008).…”

The effect of habitat fragmentation on the bee visitor assemblages of three Australian tropical rainforest tree species

Tropical forest loss and fragmentation can change bee community dynamics and potentially interrupt plant–pollinator relationships. While bee community responses to forest fragmentation have been investigated in a number of tropical regions, no studies have focused on this topic in Australia. In this study, we examine taxonomic and functional diversity of bees visiting flowers of three tree species across small and large rainforest fragments in Australian tropical landscapes. We found lower taxonomic diversity of bees visiting flowers of trees in small rainforest fragments compared with large forest fragments and show that bee species in small fragments were subsets of species in larger fragments. Bees visiting trees in small fragments also had higher mean body sizes than those in larger fragments, suggesting that small‐sized bees may be less likely to persist in small fragments. Lastly, we found reductions in the abundance of eusocial stingless bees visiting flowers in small fragments compared to large fragments. These results suggest that pollinator visits to native trees living in small tropical forest remnants may be reduced, which may in turn impact on a range of processes, potentially including forest regeneration and diversity maintenance in small forest remnants in Australian tropical countryside landscapes.
