Pollinators: First Global Risk Index for Species Declines and Effects on Humanity 16 August 2021
Pollinators: First global risk index for species declines and effects on humanity 16 August 2021 ecosystems, including many that humans and other animals rely on for nutrition. If they go, we may be in serious trouble." Dicks assembled a 20-strong team of scientists and indigenous representatives to attempt an initial evaluation of the drivers and risks for pollinator declines worldwide. The research is published today in Nature Ecology & Evolution. The top three global causes of pollinator loss are habitat destruction, followed by land management—primarily the grazing, fertilizers and crop monoculture of farming—and then widespread pesticide use, according to the study. The effect of Credit: CC0 Public Domain climate change comes in at number four, although data are limited. Perhaps the biggest direct risk to humans across all Disappearing habitats and use of pesticides are regions is "crop pollination deficit": falls in quantity driving the loss of pollinator species around the and quality of food and biofuel crops. Experts world, posing a threat to "ecosystem services" that ranked the risk of crop yield "instability" as serious provide food and wellbeing to many or high across two-thirds of the planet—from Africa millions—particularly in the Global South—as well asto Latin America—where many rely directly on billions of dollars in crop productivity. pollinated crops through small-holder farming.

UNIVERSITY of READING Delivering Biodiversity and Pollination Services on Farmland
UNIVERSITY OF READING Delivering biodiversity and pollination services on farmland: a comparison of three wildlife- friendly farming schemes Thesis submitted for the degree of Doctor of Philosophy Centre for Agri-Environmental Research School of Agriculture, Policy and Development Chloe J. Hardman June 2016 Declaration I confirm that this is my own work and the use of all material from other sources has been properly and fully acknowledged. Chloe Hardman i Abstract Gains in food production through agricultural intensification have come at an environmental cost, including reductions in habitat diversity, species diversity and some ecosystem services. Wildlife- friendly farming schemes aim to mitigate the negative impacts of agricultural intensification. In this study, we compared the effectiveness of three schemes using four matched triplets of farms in southern England. The schemes were: i) a baseline of Entry Level Stewardship (ELS: a flexible widespread government scheme, ii) organic agriculture and iii) Conservation Grade (CG: a prescriptive, non-organic, biodiversity-focused scheme). We examined how effective the schemes were in supporting habitat diversity, species diversity, floral resources, pollinators and pollination services. Farms in CG and organic schemes supported higher habitat diversity than farms only in ELS. Plant and butterfly species richness were significantly higher on organic farms and butterfly species richness was marginally higher on CG farms compared to farms in ELS. The species richness of plants, butterflies, solitary bees and birds in winter was significantly correlated with local habitat diversity. Organic farms supported more evenly distributed floral resources and higher nectar densities compared to farms in CG or ELS. Compared to maximum estimates of pollen demand from six bee species, only organic farms supplied sufficient pollen in late summer. -

Clear Plastic Bags of Bark Mulch Trap and Kill Female Megachile (Hymenoptera: Megachilidae) Searching for Nesting Sites
JOURNAL OF THE KANSAS ENTOMOLOGICAL SOCIETY 92(4), 2019, pp. 649-654 SHORT COMMUNICATION Clear Plastic Bags of Bark Mulch Trap and Kill Female Megachile (Hymenoptera: Megachilidae) Searching for Nesting Sites Casey M. Delphia1*, Justin B. Runyon2, and Kevin M. O’Neill3 ABSTRACT: In 2017, we found 17 dead females of Megachile frigida Smith in clear plastic bags of com- posted bark mulch in a residential yard in Bozeman, Montana, USA. Females apparently entered bags via small ventilation holes, then became trapped and died. To investigate whether this is a common source of mortality, we deployed unmodified bags of mulch and those fitted with cardboard tubes (as potential nest sites) at three nearby sites in 2018. We found two dead M. frigida females and five completed leaf cells in one of these bags of mulch fitted with cardboard tubes; two male M. frigida emerged from these leaf cells. In 2018, we also discovered three dead female M. frigida and three dead females of a second leafcutter bee species, Megachile gemula Cresson, in clear bags of another type of bark mulch. Both mulches emitted nearly identical blends of volatile organic compounds, suggesting their odors could attract females searching for nesting sites. These findings suggest that more research is needed to determine how common and wide- spread this is for Megachile species that nest in rotting wood and if there are simple solutions to this problem. KEYWORDS: Leafcutter bees, solitary bees, cavity-nesting bees, Apoidea, wild bees, pollinators, Megachile frigida, Megachile gemula The leafcutter bees Megachile frigida Smith, 1853 and Megachile gemula Cresson, 1878 (Megachilidae) are widespread in North America (Mitchell 1960; Michener, 2007; Sheffield et al., 2011). -

Children's Perceptions of Rainforest Biodiversity
Children’s Perceptions of Rainforest Biodiversity: Which Animals Have the Lion’s Share of Environmental Awareness? Jake L. Snaddon1., Edgar C. Turner1,2.*, William A. Foster1 1 Department of Zoology, University of Cambridge, Cambridge, Cambridgeshire, United Kingdom, 2 Bedfordshire, Cambridgeshire, Northamptonshire and Peterborough Wildlife Trusts, Bedford, Bedfordshire, United Kingdom Abstract Globally, natural ecosystems are being lost to agricultural land at an unprecedented rate. This land-use often results in significant reductions in abundance and diversity of the flora and fauna as well as alterations in their composition. Despite this, there is little public perception of which taxa are most important in terms of their total biomass, biodiversity or the ecosystem services they perform. Such awareness is important for conservation, as without appreciation of their value and conservation status, species are unlikely to receive adequate conservation protection. We investigated children’s perceptions of rainforest biodiversity by asking primary-age children, visiting the University Museum of Zoology, Cambridge to draw their ideal rainforest. By recording the frequency at which children drew different climatic, structural, vegetative and faunal components of the rainforest, we were able to quantify children’s understanding of a rainforest environment. We investigated children’s perceptions of rainforest biodiversity by comparing the relative numbers of the taxa drawn with the actual contributions made by these taxa to total rainforest biomass and global biodiversity. We found that children have a sophisticated view of the rainforest, incorporating many habitat features and a diverse range of animals. However, some taxa were over-represented (particularly mammals, birds and reptiles) and others under-represented (particularly insects and annelids) relative to their contribution to total biomass and species richness. -

Abstract: Visual and olfactory floral signals play key roles in plant-pollinator interactions. In recent decades, studies investigating the evolution of either of these signals have increased considerably. However, there are large gaps in our understanding of whether or not these two cue modalities evolve in a concerted manner. Here, we characterized the visual (i.e., color) and olfactory (scent) floral cues in bee-pollinated Campanula species by spectrophotometric and chemical methods, respectively, with Citation: Milet-Pinheiro, P.; Santos, the aim of tracing their evolutionary paths.

This results in 137 species, which is 41% of all species that occur in the Netherlands. The species of priority are: Andrena rosae, A. labialis, A. wilkella, Bombus jonellus, B. muscorum and B. veteranus. Potential species of priority are: Andrena pilipes, A. gravida Bombus ruderarius B. rupestris and Nomada bifasciata. Threats to bees are: scaling up in agriculture, eutrophication, reduction of flowers, pesticides and competition with honey bees.
