“…Pan traps worked effectively for a wide range of pollinators [63] and have already been used extensively [64][65][66][67][68]. They should be used in three different colors (yellow, blue, and white) [63,[69][70][71], mounted at standardized height relative to the vegetation [71,72], and should be spaced apart by at least 3-5 m for replication within sites [73]. …”

Historical and recent land use affects ecosystem functions in subtropical grasslands in Brazil

Abstract. Land-use changes such as conversion of semi-natural grasslands to agriculture, silviculture, or highintensity pastures affect biodiversity and ecosystem functions and services. However, which ecosystem functions are affected when highly diverse grasslands are converted remains largely unknown. As a model system, we studied 80 grasslands in Rio Grande do Sul, southern Brazil, comprising exceptionally diverse permanent grasslands that are traditionally managed with burning of accumulated biomass and moderate grazing, and four additional grassland types with different present or historical management: permanent grasslands with reduced or increased current management intensity and secondary grasslands after past agricultural or silvicultural use. We measured ten ecosystem functions covering all major below-and aboveground ecosystem components and the processes that link them, using the novel rapid ecosystem function assessment approach. Ecosystem functions included primary and secondary production, and species interactions, that is, herbivory, pollination, predation, seed dispersal, and decomposition. Ecosystem functions differed significantly among grassland types, most distinctly between permanent and secondary grasslands. Historical land-use changes to agriculture and silviculture led to altered ecosystem functions even after reconversion to grassland, including lower primary and secondary production, lower decomposition, lower seed dispersal capabilities, and higher invertebrate herbivory. Current management practices explained additional variation in some ecosystem functions, including strong positive effects of intensified management on secondary production. Other ecosystem functions such as pollination and predation were not affected. The findings suggest that conversion of grasslands to more intensive land-use types has long-lasting consequences for some ecosystem functions, with effects persisting even many years after reconversion, resulting in changes in the ecosystem services provided by these grasslands.

“…Pan traps of different colors placed at different heights have been successfully used as complementary methods in monitoring bee communities across a number of habitats and landscapes of both tropical and temperate environments (e.g., Wilson et al 2008, Tuell and Isaacs 2009, Droege et al 2010, Ulyshen et al 2010, Nuttman et al 2011, Gonçalves and Oliveira 2013, Geroff et al 2014. These traps have become popular among bee ecologists and conservation biologists because they are readily available, inexpensive, and are not collector biased.…”

Pan traps are among the most popular methods employed to survey bees and changes in some functional traits, such as body size, are increasingly used to understand how bee communities and species respond to landscape changes. Herein we assess body size differences between bees captured at ground-level and elevated (70 cm) pan traps in unmanaged urban habitats in northwestern Turkey. We compare body size at the community level as well as for the sweat bee Lasioglossum malachurum (Kirby) (Halictidae: Halictini), the most abundant species. We also compare the diversity, richness and abundance of bees sampled at both heights. A total of 31 species (13 genera of three families) were captured. We did not find significant differences in the abundance nor in the species richness between heights, and Simpson's indices were similar. At the community level, average intertegular distance was significantly greater in bees collected at the elevated traps than on the ground. Intertegular distances in L. malachurum did not differ between elevated and ground-level pan traps. Our results show an effect of pan trap height on bee body size in the urban habitat surveyed, thus suggesting that assessing bee body size from samples collected with either ground-level or elevated pan traps alone might result in biased estimates of this functional trait.
