Do amino and fatty acid profiles of pollen provisions correlate with bacterial microbiomes in the mason beeOsmia bicornis?

Bee performance and well-being strongly depend on access to sufficient appropriate resources, in particular pollen nectar of flowers, which constitute the major basis bee nutrition. Pollen-derived microbes appear play an important but still little explored role plant pollen–bee interaction dynamics, e.g. through affecting quantities ratios nutrients. To better understand how collected by bees may affect larval health nutrition, we investigated correlations between floral, bacterial nutritional composition provisions gut communities solitary megachilid Osmia bicornis . Our study reveals quality complete community as well individual members both guts. In fatty acid profiles interact with specific community, indicating that pollen-derived bacteria provisioning.

Missing the bigger picture: Why insect monitoring programs are limited in their ability to document the effects of habitat loss

Conservation Letters, Journal Year: 2023, Volume and Issue: 16(3)

Published: April 3, 2023

Abstract The fate of insects in the Anthropocene has been widely discussed scientific literature, popular media, and policy circles. This recent attention is justified because reductions insect abundance diversity have potential to undermine stability terrestrial ecosystems. Reports declines also accompanied by skepticism that healthy be expected discussion. However, we are concerned about a prevalent misconception equates reports from monitored natural areas with global status insects. In vast majority cases, for arthropods undeveloped thus do not record or even necessarily reflect masses continuously being impacted habitat loss urban, suburban agricultural expansion. We address this discuss ways which conservation can enhanced correctly locating results monitoring programs within our broader knowledge biodiversity loss.

Negative effects of urbanisation on diurnal and nocturnal pollen‐transport networks

Ecology Letters, Journal Year: 2023, Volume and Issue: 26(8), P. 1382 - 1393

Published: June 5, 2023

Abstract Pollinating insects are declining due to habitat loss and climate change, cities with limited floral resources may be particularly vulnerable. The effects of urban landscapes on pollination networks remain poorly understood, comparative studies taxa divergent niches lacking. Here, for the first time, we simultaneously compare nocturnal moth diurnal bee pollen‐transport using DNA metabarcoding ask how affected by increasing urbanisation. Bees moths exhibited substantial divergence in communities plants they interact with. Increasing urbanisation had comparable negative both taxa, significant declines pollen species richness. We show that an important, but overlooked, component wild flowering plants, horticultural crops, trees. Our findings highlight need include non‐bee when assessing status critical plant‐insect interactions urbanised landscapes.

Linking climate warming and land conversion to species’ range changes across Great Britain

Nature Communications, Journal Year: 2023, Volume and Issue: 14(1)

Published: Oct. 30, 2023

Abstract Although increased temperatures are known to reinforce the effects of habitat destruction at local landscape scales, evidence their additive or interactive is limited, particularly over larger spatial extents and longer timescales. To address these deficiencies, we created a dataset land-use changes 75 years, documenting loss half (>3000 km 2 ) semi-natural grassland Great Britain. Pairing this with climate change data, tested for relationships distribution in birds, butterflies, macromoths, plants ( n = 1192 species total). We show that individual warming land conversion unambiguously persistence probability 40% species, decreased it 12%, were reflected both range contractions expansions. Interactive relatively rare, being detected less than 1 5 overall effect on extinction risk was often weak. Such individualistic responses emphasise importance including species-level information policies targeting biodiversity adaptation.

Ecological and life‐history traits predict temporal trends in biomass of boreal moths

Insect Conservation and Diversity, Journal Year: 2023, Volume and Issue: 16(5), P. 600 - 615

Published: May 29, 2023

Abstract Dramatic insect declines, and their consequences for ecosystems globally, have received considerable attention recently. Yet, it is still poorly known if ecological life‐history traits can explain declines whether decline occurs also at high latitudes. Insects' diversity abundance are dramatically lower latitudes compared to the tropics, insects might benefit from climate warming in high‐latitude environments. We adopted a trait‐ biomass‐based approach estimate temporal change between 1993 2019 Finnish macro‐moth communities by using data 85 long‐running light traps. analysed spatio‐temporal variation biomass of moth functional groups with Joint Dynamic Species Distribution Models while accounting environmental variables. did not detect any declining trends total groups, most were stable over time. Moreover, increased species coniferous trees, lichens, or mushrooms as hosts, multivoltine species, well monophagous oligophagous feeding on trees. found that length temperature growing season, winter climatic conditions, habitat structure all partially explained biomass. Although boreal rapidly changing due turnover, terms they seem contradict trend dramatic observed globally. This may lessen immediate possibility negative bottom‐up trophic cascades food webs.
