When honeybees come to town: Critical aspects of urban beekeeping and opportunities for regulation

People and Nature, Volume 8, Issue 3, Page 528-540, March 2026.
Abstract Urban areas are increasingly valued for their role in conserving wild pollinators. Honeybees are often regarded as ambassador species for pollinator conservation, and beekeeping is frequently perceived as a pro‐biodiversity activity, which has become highly popular in urban areas.

Pollination of Rapeseed (Brassica napus) by Africanized Honeybees (Hymenoptera: Apidae) on Two Sowing Dates

Anais da Academia Brasileira de Ciências, 2014
In this study, performed in the western part of the state of Paraná, Brazil, two self-fertile hybrid commercial rapeseed genotypes were evaluated for yield components and physiological quality using three pollination tests and spanning two sowing dates ...

Community‐level effects of Müllerian mimicry on pollinator diversity and functioning

Functional Ecology, Volume 40, Issue 3, Page 599-610, March 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Müllerian mimicry, a mutualistic interaction in which harmful species evolve similar warning signals, is often accompanied by niche divergence among mimetic species. While these aspects have traditionally been studied in an evolutionary context, their community‐level ...

Efeito da polinização por abelhas e outros insetos na produção de sementes de cebola Effect of pollination by bees and other insects on the production of onion seeds

Pesquisa Agropecuária Brasileira, 2003
A deficiência de polinização tem sido apontada como uma das causas da baixa produção de sementes na cultura da cebola. O objetivo deste trabalho foi avaliar a relação da presença de abelhas e outros insetos em flores de duas cultivares de cebola, Allium ...

Urban rendezvous: Spatiotemporal overlap is more important than abundance and trait matching for urban plant–pollinator interactions

Journal of Applied Ecology, Volume 63, Issue 1, January 2026.
Our study shows that the generalized structure of urban plant–pollinator interactions is mirrored in the mechanisms that shape them, as interactions are governed primarily by less restrictive drivers such as abundance and spatiotemporal overlap rather than by trait matching.

Movement Strategies of Neotropical Nectarivorous Birds: Insights From High‐Andean Hummingbirds and Flowerpiercers

Biotropica, Volume 58, Issue 1, January 2026.
Nectar is a highly variable, mostly unpredictable resource in tropical mountains. How do nectarivorous birds such as this male Great Sapphirewing cope? Fine‐scaled tracking of hummingbirds and flowerpiercers shows flexibility in daily movement strategies in the high Andes, possibly in response to fluctuating local conditions such as weather and ...

Quando um visitante floral é um polinizador? [PDF]

Rodriguésia, 2016
Resumo Os visitantes florais são animais que buscam, nas flores, recursos para si ou para sua prole. Às vezes uma mesma planta pode receber um espectro grande de visitantes, como é o caso de espécies cujas flores oferecem muito néctar. Porém, nem todo visitante floral realiza a polinização.

Landscape and crop diversity contributes to greater yield stability

Journal of Applied Ecology, Volume 62, Issue 11, Page 3092-3104, November 2025.
These findings underscore the importance of promoting crop diversity and maintaining heterogeneous agricultural landscapes, particularly in pollinator‐dependent crops. Promoting diverse agricultural landscapes with balanced heterogeneity can enhance the resilience of agricultural systems to climate change and contribute to long‐term food security ...
