Natur på skolgården för lärande, hälsa och hållbarhet
- 2024. - 2024

Rapport (populärvet., debatt m.m.)abstract
- Gröna och artrika utemiljöer främjar barns och ungas välbefinnande och kunskap, bådegenom hälsofördelar kopplade till biologisk mångfald och genom att skapa förutsättningarför lek och lärande om natur och miljöfrågor. Skolgården skulle kunna bidra till allt detta,men är idag i hög grad en outnyttjad plats för biologisk mångfald och klimatanpassningav städer. I denna policy brief presenteras huvudsakliga motiv och möjliga åtgärder för attutveckla gröna miljöer och biologisk mångfald på skolgårdar och förskolegårdar.

Skånes humlor
- 2019
-
Annan publikation (populärvet., debatt m.m.)abstract
- Arbetet med affischen har gjorts med stöd av Lunds universitet. Ekologen Anna Persson har skrivit informativa texter och Karin Johnson på Biologiska museet har tagit fram humlearter från insektssamlingarna som sedan har illustrerats av Maj Persson, biolog och illustratör. Bilderna visar honan (drottningen) och hanen (drönaren) av varje skånsk humleart.

Evolutionary plant–pollinator responses to anthropogenic land-use change : impacts on ecosystem services

Tidskriftsartikel (refereegranskat)abstract
- Agricultural intensification at field and landscape scales, including increased use of agrochemicals and loss of semi-natural habitats, is a major driver of insect declines and other community changes. Efforts to understand and mitigate these effects have traditionally focused on ecological responses. At the same time, adaptations to pesticide use and habitat fragmentation in both insects and flowering plants show the potential for rapid evolution. Yet we lack an understanding of how such evolutionary responses may propagate within and between trophic levels with ensuing consequences for conservation of species and ecological functions in agroecosystems. Here, we review the literature on the consequences of agricultural intensification on plant and animal evolutionary responses and interactions. We present a novel conceptualization of evolutionary change induced by agricultural intensification at field and landscape scales and emphasize direct and indirect effects of rapid evolution on ecosystem services. We exemplify by focusing on economically and ecologically important interactions between plants and pollinators. We showcase available eco-evolutionary theory and plant–pollinator modelling that can improve predictions of how agricultural intensification affects interaction networks, and highlight available genetic and trait-focused methodological approaches. Specifically, we focus on how spatial genetic structure affects the probability of propagated responses, and how the structure of interaction networks modulates effects of evolutionary change in individual species. Thereby, we highlight how combined trait-based eco-evolutionary modelling, functionally explicit quantitative genetics, and genomic analyses may shed light on conditions where evolutionary responses impact important ecosystem services.

Intensive management reduces butterfly diversity over time in urban green spaces

- Loss and fragmentation of semi-natural grasslands have had negative consequences for grassland biodiversity, such as butterflies. Urban parks and other urban green spaces have so far largely been overlooked as suitable butterfly habitats, although they could potentially sustain diverse butterfly populations over time. We analysed the temporal change in butterfly species assemblages in urban green spaces in the city of Malmö, Southern Sweden. We studied changes in species richness and abundance of butterflies between 2006 and 2015 in 20 public urban green spaces, characterized by different management regimes. We sampled butterflies in traditional parks with intense grass cutting regimes, in semi-natural grasslands mowed only a few times per year, and in un-managed or irregularly managed ruderal sites. We found a slight increase in the total number of butterfly species in the study area, but a general decline in local species numbers in urban green spaces. Traditional urban parks had the greatest loss of species over time, and altogether the lowest number of species. In contrast, semi-natural parks and ruderal sites had higher numbers of butterfly species and also lost fewer species over time. Our study shows that intensive management strategies in urban green spaces have a negative impact on butterfly assemblages over time. We suggest that less intensive management strategies can be used to create high-quality areas for flower-visiting insects in urban green spaces, possibly in combination with planting larval host plant species, depending on the park type and design.

- Bumblebees are a key taxon contributing to the provision of crop pollination and ecosystem functioning. However, land use and climate change are two of the main factors causing bee decline across the world. In this study, we investigated how the flight period of bumblebee spring queens has shifted over the last century in Sweden, and to what extent such shifts depended on climate change, landscape context, latitude, and the phenology of bumblebee species. We studied ten species of bumblebees and used observations from museum specimens covering 117 years from the southernmost region in Sweden (Scania), combined with citizen-reported observations during the past 20 years across Sweden. We found that the flight period of bumblebees has advanced by 5 days on average during the last 20 years across Sweden. In the agriculture-dominated region of Scania, we found that in the late 2010s bumblebee spring queen activity in simplified landscapes had advanced by on average 14 days, compared to 100 years ago. In addition, in simplified landscapes the flight period of early species was significantly earlier compared to in complex landscapes. Our results provide knowledge on the intraspecific variation of phenological traits, indicating that early species (often common species) exhibit a higher plastic response to the environment, which may facilitate adaptation to both climate and landscape changes, compared to the late species of which many are declining.

Urban green spaces in Dhaka, Bangladesh, harbour nearly half the country's butterfly diversity

Tidskriftsartikel (refereegranskat)abstract
- Cities currently harbour more than half of the world's human population and continued urban expansion replaces natural landscapes and increases habitat fragmentation. The impacts of urbanisation on biodiversity have been extensively studied in some parts of the world, but there is limited information from South Asia, despite the rapid expansion of cities in the region. Here, we present the results of monthly surveys of butterflies in three urban parks in Dhaka city, Bangladesh, over a 3-year period (January 2014 to December 2016). We recorded 45% (137 of the 305 species) of the country's butterfly richness, and 40% of the species detected are listed as nationally threatened. However, butterfly species richness declined rapidly in the three study areas over the 3-year period, and the decline appeared to be more severe among threatened species. We developed linear mixed effect models to assess the relationship between climatic variables and butterfly species richness. Overall, species richness was positively associated with maximum temperature and negatively with mean relative humidity and saturation deficit. Our results demonstrate the importance of urban green spaces for nationally threatened butterflies. With rapidly declining urban green spaces in Dhaka and other South Asian cities, we are likely to lose refuges for threatened fauna. There is an urgent need to understand urban biodiversity dynamics in the region, and for proactive management of urban green spaces to protect butterflies in South Asia.
