Bees and pollinators: small creatures but great allies on earth
20/05/2022
Almonds, apples, coffee, or strawberries are all foods that we can enjoy thanks to the meticulous pollination activities of bees and other pollinating insects. In addition to food, these insects indirectly contribute to the provision of medicines and the production of fiber, biofuels, and othe...
Do agroecological practices enhance the supply of ecosystem services? A comparison between agroecological and conventional horticultural farms
01/01/2022
This study compared agroecological and conventional horticultural farms in terms of agroecological practices and ecosystem services supply. We conducted biophysical samplings and interviews on 24 agroecological and conventional farms over two summers in the Madrid Region (Spain).
Can landscape level semi-natural habitat compensate for pollinator biodiversity loss due to farmland consolidation?
01/01/2021
Traditional farming landscapes in China consist of small irregular fields with an intimately interspersed semi-natural habitat network of field margins, but are increasingly converted into consolidated ones that consist of standardized fields with reduced areas of field margins and other semi-natural habitat.
Pollinators contribute to the maintenance of flowering plant diversity
01/01/2021
Mechanisms that favour rare species are key to the maintenance of diverse communities. One of the most critical tasks for conservation of flowering plant biodiversity is to understand how plant–pollinator interactions contribute to the maintenance of rare species.
Revisiting the economic valuation of agricultural losses due to large-scale changes in pollinator populations
01/01/2021
Public concerns over declines in crop pollinator populations and their potential impact on food production have increased the need for economic valuations of the corresponding ecosystem services, particularly as policymakers have to justify costly agro-environmental measures to sustain them.
Fragmented landscapes affect honey bee colony strength at diverse spatial scales in agroecological landscapes in Kenya
01/01/2021
Landscape fragmentation and habitat loss at multiple scales directly affect species abundance, diversity, and productivity. There is a paucity of information about the effect of the landscape structure and diversity on honey bee colony strength in Africa.
Agroecological Strategies to Safeguard Insect Pollinators in Biodiversity Hotspots: Chile as a Case Study
01/01/2021
Industrial agriculture (IA) has been recognized among the main drivers of biodiversity loss, climate change, and native pollinator decline. Here we summarize the known negative effects of IA on pollinator biodiversity and illustrate these problems by considering the case of Chile, a “world biodiversity hotspot” (WBH) where food exports account for a considerable share of the economy in this country.
Natural habitat partially mitigates negative pesticide effects on tropical pollinator communities
01/01/2021
Land-use change and pesticides have been identified as two of the main causes behind pollinator decline. Understanding how these factors affect crop pollinator communities is crucial to inform practices that generate optimal pollination and ensure sustainable food production.
Diversity and composition of pollen loads carried by pollinators are primarily driven by insect traits, not floral community characteristics
01/01/2021
Flowering plants require conspecific pollen to reproduce but they often also receive heterospecific pollen, suggesting that pollinators carry mixed pollen loads. However, little is known about drivers of abundance, diversity or composition of pollen carried by pollinators
The role of functional diversity and facilitation in small-scale pollinator habitat
01/01/2021
People in urban and rural areas are planting habitat patches for pollinators in response to growing public awareness of the risks of pollinator declines; yet research rarely has been undertaken to inform the composition of such patches
Nocturnal pollinators strongly contribute to pollen transport of wild flowers in an agricultural landscape
01/01/2020
Dramatic declines in diurnal pollinators have created great scientific interest in plant–pollinator relationships and associated pollination services. Existing literature, however, is generally focused on diurnal pollinating insect taxa, especially on Apidae (Hymenoptera) and Syrphidae (Diptera) pollinators, while nocturnal macro-moths that comprise extremely species-rich flower-visiting families have been largely neglected.
The apiary influence range: A new paradigm for managing the cohabitation of honey bees and wild bee communities
01/01/2020
There is an emerging controversy among bee biologists, land managers and beekeepers about the legitimacy of high-density beekeeping in natural protected areas due to the risks of detrimental interactions with local wild bees.
Perceptions of keepers of stingless bees (Tetragonula, Austroplebeia) regarding Aboriginal beliefs and practices in Australia
01/01/2020
This study sought to better understand the diversity of keepers of stingless bees and indigenous social representations based in Brisbane and the adjoining regions, the center of stingless beekeeping in Australia; and to analyze the database in relation to highlighted cultural and spatial-temporal considerations.
Assessing indigenous and local knowledge of farmers about pollination services in cucurbit agro-ecosystem of Punjab, Pakistan
01/01/2020
In the present study, we have investigated the knowledge of farmers about bees and pollination in general in three districts i.e. Multan, Bahawalpur and Khanewal of southern Punjab, Pakistan.
Saving the Other Bees: The Resurgence of Stingless Beekeeping in the Zona Maya
01/01/2020
This paper discusses strategies for salvaging biodiversity through a case study exploring the revitalisation of keeping stingless bees in the Yucatan Peninsula. While once Melipona beecheii was at risk of extinction, fifteen years later the species and meliponiculture practices are thriving.
Pollinator-friendly management does not increase the diversity of farmland bees and wasps
01/01/2015
In order to reverse declines in pollinator populations, numerous agri-environment schemes have been implemented across Europe, predominantly focused on increasing the availability of floral resources.
