“…Habitat alteration and the African honeybee invasion during the course of on-going pollination research has provided both general and occasionally unexpected insights (Kevan 1999). In Costa Rica, for instance, Frankie et al (cited in Kevan 1999) used a focal tree species to show marked change in native bees present at the beginning and end of a 23-year interval.…”

“…Of particular interest are insects with important ecological functions, such as predators, parasites and pollinators; these are frequently used in studies evaluating the effects of habitat loss on biodiversity (Tscharntke 1992;Kevan 1999;SteffanDewenter & Tscharntke 2002). However, such studies involving the Atlantic Forest are still rare (Viana et al 2006;Loyola & Martins 2008, 2009).…”

Nesting and use of pollen resources by Tetrapedia diversipes Klug (Apidae) in Atlantic Forest areas (Rio de Janeiro, Brazil) in different stages of regeneration. The nesting in trap-nests and use of pollen sources in larval food by Tetrapedia diversipes Klug, 1810 (Apidae) was compared between regenerating areas of Atlantic Forest. The study was conducted between April 2008 and October 2009 at União Biological Reserve, Rio de Janeiro, Brazil. T. diversipes nested in 66 trap-nests and showed a peak of nesting during the months of highest rainfall. The most frequent pollen type in brood cells during the wet season was Dalechampia sp. 1. During the dry season, the type Ludwigia sp. was the most frequent, followed by Dalechampia sp. 2. The high frequency of Dalechampia and Ludwigia species in the larval food, observed in both habitats and in the two seasons could be considered relevant for T. diversipes, suggesting highly selective diet based primarily on two plant species unrelated, but similar in size of pollen grains.
Nidificação e uso de fontes de pólen por Tetrapedia diversipes Klug (Apidae) em áreas de Mata Atlântica (Rio de Janeiro, Brasil) em diferentes estágios de regeneração. A nidificação em ninhos-armadilha e o uso de fontes de pólen no alimento larval por Tetrapedia diversipes Klug, 1810 (Apidae) foram comparados entre áreas de Floresta Atlântica em regeneração. O estudo foi realizado entre abril de 2008 e outubro de 2009 na Reserva Biológica União, Rio de Janeiro, Brasil. T. diversipes nidificou em 66 ninhos-armadilha e apresentou um pico de nidificação durante os meses de maior precipitação pluviométrica. O tipo polínico mais frequente nas células de cria durante a estação chuvosa foi Dalechampia sp. 1. Durante a estação seca, o tipo Ludwigia sp. foi o mais frequente, seguido de Dalechampia sp. 2. A alta frequência de espécies de Dalechampia e Ludwigia no alimento larval, observada em ambos os habitats e nas duas estações deve ser considerada um fato relevante para T. diversipes, sugerindo uma dieta altamente seletiva baseada primariamente em duas espécies vegetais não relacionadas, porém semelhantes quanto ao tamanho dos grãos de pólen

“…This lack of knowledge concerning the status and trends of the majority of species is worrying, but there is even greater concern for species that play important functional roles, such as pollinators (NRC, 2006;Potts et al, 2010a). Pollination is an essential ecosystem service, vital to the maintenance both of wild plant communities and agricultural productivity; and pollinators themselves can act as indicators of environmental health (Kevan, 1999). The value of insect pollination to European agriculture is estimated to be worth ~€22 billion per year (Gallai et al, 2009) with 84% of European crop varieties dependent, at least in part, on insect pollinators (Williams, 1994).…”

SummaryPollinating insects form a key component of European biodiversity, and provide a vital ecosystem service to crops and wild plants. There is growing evidence of declines in both wild and domesticated pollinators, and parallel declines in plants relying upon them. The STEP project (Status and Trends of European Pollinators, 2010-2015, www.step-project.net) is documenting critical elements in the nature and extent of these declines, examining key functional traits associated with pollination deficits, and developing a Red List for some European pollinator groups. Together these activities are laying the groundwork for future pollinator monitoring programmes. STEP is also assessing the relative importance of potential drivers of pollinator declines, including climate change, habitat loss and fragmentation, agrochemicals, pathogens, alien species, light pollution, and their interactions. We are measuring the ecological and economic impacts of declining pollinator services and floral resources, including effects on wild plant populations, crop production and human nutrition. STEP is reviewing existing and potential mitigation options, and providing novel tests of their effectiveness across Europe. Our work is building upon existing and newly developed datasets and models, complemented by spatially-replicated campaigns of field research to fill gaps in current knowledge. Findings are being integrated into a policy-relevant framework to create evidence-based decision support tools. STEP is establishing communication links to a Journal of Apicultural Research 50(2): 152-164 (2011)
