“…According to the beekeepers in our study, the honeybee Apis cerana cerana is declining in Western Nepal. The reported honeybee decline is likely indicative of a regional trend, consistent with previous reports of declining Apis cerana populations in Nepal and throughout Asia [21,30]. Because of declining bee populations, honey yields and the number of occupied beehives are also decreasing.…”

In understudied regions of the world, beekeeper records can provide valuable insights into changes in pollinator population trends. We conducted a questionnaire survey of 116 beekeepers in a mountainous area of Western Nepal, where the native honeybee Apis cerana cerana is kept as a managed bee. We complemented the survey with field data on insect–crop visitation, a household income survey, and an interview with a local lead beekeeper. In total, 76% of beekeepers reported declines in honeybees, while 86% and 78% reported declines in honey yield and number of beehives, respectively. Honey yield per hive fell by 50% between 2012 and 2022, whilst the number of occupied hives decreased by 44%. Beekeepers ranked climate change and declining flower abundance as the most important drivers of the decline. This raises concern for the future food and economic security of this region, where honey sales contribute to 16% of total household income, and where Apis cerana cerana plays a major role in crop pollination, contributing more than 50% of all flower visits to apple, cucumber, and pumpkin. To mitigate further declines, we promote native habitat and wildflower preservation, and using well-insulated log hives to buffer bees against the increasingly extreme temperature fluctuations.

This study aimed to identify challenges in the management of conservation units through a literature review and validate them from the perspective of professionals in the field, considering the context of the Amazon Region. To achieve this, a literature review and a survey were conducted with professionals working in the field of conservation unit management. The collected data were analyzed using the Lawshe method. The results indicated that ten out of fifteen analyzed challenges were validated by the professionals. The validated challenges included: lack of financial resources, urbanization advancement, land conflicts, monitoring and enforcement, climate change, deforestation and illegal exploitation, lack of environmental education, political bureaucracy, conflicts with local communities, and corruption. The validated challenges mainly relate to management issues and the lack of more efficient governance strategies. The findings provide valuable insights for the promotion of sustainable conservation policies in the Amazon.

“…To qualify species–habitat associations, studies often rely on expert‐collected (EC) data. However, such data have severe limitations, particularly in Southeast Asia, where there is a substantial data gap (Feeley & Silman, 2011) including for bees (Dorey et al., 2023; Orr et al., 2021; Warrit et al., 2023). Consequently, community science (CS) data have huge potential to contribute to ecological studies, particularly where professionally collected data are lacking or unfeasible to collect at large scales (Brown & Williams, 2019; Theobald et al., 2015).…”

Community science enhances modelled bee distributions in a tropical Asian city

Bees and the ecosystem services they provide are vital to urban ecosystems, but little is understood about their distributions, particularly in the Asian tropics. This is largely due to taxonomic impediments and limited inventorying, monitoring, and digitization of occurrence records. While expert collections (EC) are demonstrably insufficient by themselves as a data source to model and understand bee distributions, the boom of community science (CS) in urban areas provides an untapped opportunity to learn about bee distributions within our cities. We used CS observations in combination with EC observations to model the distribution of bees in Singapore, a small tropical city‐state in Southeast Asia. To address the restricted spatial context, we performed multiple bias corrections and show that species distribution models performed well when estimating the distribution of habitat specialists with distinct range limits detectable within Singapore. We successfully modelled 37 bee species, where model statistics improved for 23 species upon the incorporation of CS observations. Nine species had insufficient EC observations to obtain acceptable models, but could be modelled with the incorporation of CS observations. This is the first study to combine both EC and CS observations to map and model the occurrences of tropical Asian bee species for a highly urbanized region at such fine resolution. Our results suggest that urban landscapes with impervious surfaces and higher temperatures are less suitable for bee species, and such findings can be used to advise the management of urban landscapes to optimize the diversity of bee pollinators and other organisms.
