Are orchid bees at risk? First comparative survey suggests declining populations of forest-dependent species

Abstract: The two largest Atlantic Forest remnants in the state of Espírito Santo, eastern Brazil, namely 'Reserva Biológica de Sooretama' (REBIO Sooretama) and 'Reserva Natural Vale' (RNV), were surveyed for their orchid-bee faunas. Seventeen scent baits were used to attract orchid-bee males. Three-thousand, two hundred and twenty-five males belonging to 24 species were actively collected with insect nets during 100 hours in March, April and December, 2009. In comparison with a previous study in the same area twelve ye… Show more

“…Roubik (2004a) had already suggested that surveys of orchid-bee males with scent baits during a single day have great utility, and may reveal almost as much about local community structure as studies lasting a full year. The protocol proposed by Nemésio (2010b) has already been used in more than twenty areas in northeastern Brazil (Nemésio, 2010b; this study), southern Bahia (Nemésio, 2011a(Nemésio, , 2013a, northern Espírito Santo (Nemésio, 2011b(Nemésio, , 2013b, Minas Gerais (Nemésio, 2012c;Nemésio and Paula, 2013), and the Peruvian Amazon (Nemésio et al, 2014), always with a high number of collected specimens during a relatively short period of time. With more than 3,000 bees collected in only ten days, the present study revealed one of the highest abundances ever recorded with this 20-hour sampling strategy, only rivalled by the regions of Monte Pascoal, in southern Bahia (Nemésio, 2013d), and Linhares, in northern Espírito Santo (Nemésio, 2013b).…”

“…Some euglossine species are apparently sensitive to environmental disturbances (Powell and Powell 1987;Tonhasca et al 2002;Giangarelli et al 2009;Nemésio 2013), such as forest fragmentation and reduction in fragment size (Powell and Powell 1987;Sofia and Suzuki 2004;Giangarelli et al 2009). Apart from reductions in the abundance of orchid bees in forest fragments of reduced size, studies have shown that some species may have stronger dispersal limitations in fragmented landscapes, and the type of matrix may also affect the dispersal of some species of the group differently (Powell and Powell 1987;Milet-Pinheiro and Schlindwein 2005).…”
