“…While this is good news for safeguarding pollination services provided by bumble bees, it poses considerable conservation challenge. Agricultural areas, particularly intensive agricultural areas, may lack high quality habitat, often use pesticides which can be harmful, may be a source of pathogen exposure and sites of high competition for floral resources from managed bees (Cameron & Sadd, 2020; Colla et al, 2006; de Pereira et al, 2021; Grixti et al, 2009; Siviter et al, 2023; Szabo et al, 2012). Agricultural lands within conservation priority areas should be managed for more bee‐friendly practices including incorporating semi‐natural habitats, reducing or eliminating pesticide use, restricting the spread of disease from managed bees and providing enough natural floral resources to mitigate competition (Crone & Williams, 2016; Hemberger et al, 2021; Klatt et al, 2020; Miller et al, 2023; Purvis, Meehan, & Lindo, 2020).…”

Many bumble bee species are declining globally from multiple threats including climate change. Identifying conservation priority areas with a changing climate will be important for conserving bumble bee species. Using systematic conservation planning, we identified priority areas for 44 bumble bee species in Canada under current and projected climates (year 2050). Conservation priority areas were identified as those that contained targeted amounts of each species predicted occurrence through climate envelope models, while minimizing the area cost of conserving the identified conservation priority areas. Conservation priority areas in the two periods were compared to established protected areas and land cover types to determine the area of current and future priority sites that are protected and the types of landscapes within priority areas. Notably, conservation priority areas were rarely within established protected areas. Priority areas were most often in croplands and grasslands, mainly within the mountain west, central and Southern Ontario, Northern Quebec, and Atlantic Canada under all climate scenarios. Conservation priority areas are predicted to increase in elevation and latitude with climate change. Our findings identify the most important regions in Canada for conserving bumble bee species under current and future climates including consistently selected future sites.

“…In this context, pollinators are also called forest farmers because they are vital in spreading plant seeds to various forest areas and eventually growing new plants to maintain forest ecosystems, starting with a succession of Ficus trees (Shafie et al, 2023). In this regard, the low level of competition and the distance between each other influences the success rate of pollinators (Siviter et al, 2023).…”

This study aims to explore the concepts of ecology and biodiversity, the value of environmental preservation in gunungan wayang kulit purwa, and its correlation to science learning or environmental education in a science subject at the junior high school level to increase environmental awareness. This research employed a qualitative descriptive approach. This research included ethnographic research associated with symbolic interpretation in anthropology. The informants of this study were a puppeteer (dalang), a javanology expert, a gunungan wayang kulit purwa creator, and a biodiversity expert chosen by purposive sampling. Data were collected through semi-structured interviews, literature reviews, and content analysis. Data triangulation was applied to ensure the data validity. The data were analyzed using a spiral analysis model, including managing, reading, marking, describing, classifying, interpreting, and visualizing data continuously. The study results show that the gunungan wayang kulit purwa contains the conservation value and concept of ecology and biodiversity. This concept has a correlation with the material on ecology and biodiversity in the independent curriculum in a science subject at schools. The ecological concept includes biotic and abiotic components, symbiosis, pollinators and predators, food chains, food webs, competition, and the value of environmental preservation. The findings in the form of a link between ecological concepts and biodiversity in the gunungan wayang kulit purwa have implications for the potential use of gunungan wayang kulit purwa as a learning resource for science education in schools or environmental education to increase environmental awareness of the young generation.

“…While managed bees are the main provisioners of pollination services in most agro‐ecosystems (Free, 1993; Gallai et al, 2009), recent work has shown that pollinator diversity increases crop yield and quality (Katumo et al, 2022). Moreover, as the health and abundance of wild and managed bee populations continue to be challenged by multiple factors (Siviter et al, 2023), there is increased interest in understanding the pollination potential of alternate animal species (Stavert et al, 2018). While much attention should deservedly be paid to non‐bee hymenopteran pollinators for performing pollination services, insects from other orders, such as the Lepidoptera, Coleoptera and Diptera, have been demonstrated as viable options for various production systems.…”

Pollen associated with a Texas population of blow flies‐(Diptera: Calliphoridae) highlights underappreciated aspects of their biology

Over 80% of agricultural crops rely on insect pollination. Thus, pollinator biodiversity is critical for augmented plant yield and quality. Blow flies (Diptera: Calliphoridae) are acknowledged pollinators of several crops. However, there are many open questions regarding their importance in pollination ecology. For instance, there has not been a comprehensive assessment of pollen use by blow flies, and thus, it is unknown whether individuals visit few or many plant types per trip. At least one blow fly species (Lucilia sericata) can digest pollen and use the protein therein as an oogenic resource. However, it is unknown whether this is a commonly used strategy for protein acquisition, given that they are more commonly associated with faeces, carrion and myiasis. We surveyed the pollen found in blow fly guts to determine whether blow flies (a) consume pollen, and if so, which types of pollen; (b) exhibit species‐specific pollen use and (c) demonstrate sex‐specific pollen use. We collected blow flies from natural habitats around Central Texas from 2016 to 2019 and dissected their guts to look for the presence of pollen. We found widespread use of pollen from a variety of plants by six blow fly species and discovered a bias in the amount of pollen collected by female blow flies compared with males in some, but not all fly species. Pollen represents a relatively underappreciated aspect of blow fly biology, with the potential for several underappreciated ecological impacts ranging from disease ecology to plant diversity.
