Shifts in cuticular hydrocarbon profiles of bees and wasps primarily reflect temperature variations rather than the amount of sealed ground surfaces in an urban landscape

Journal of Zoology, EarlyView.
The Urban Heat Island Effect (UHI) can potentially subject insects to heat and desiccation stress and likely induce shifts in their cuticular hydrocarbon (CHC) profile. We expected that warmer urbanized areas favour longer chain length of hydrocarbons as well as higher abundance of n‐alkanes in three Hymenoptera species. We found that temperature, more

Pollinator efficiency, rather than bee decline, explains a shift to hummingbird pollination in tropical montane forests

New Phytologist, EarlyView.
Hummingbird pollination is a hallmark of American plant diversity and has long been thought to evolve in tropical mountains due to declining bee activity. Using sister species of Costus specialized on bees (C. kuntzei) and hummingbirds (C. wilsonii), we show that this shift is not driven by reduced bee visitation with elevation, but by greater ...

Sensing Frames: A Contribution to Sensory Pluralism

Sociological Forum, EarlyView.
ABSTRACT Are expressions like “sense of responsibility,” “sense of community,” and “business acumen” merely metaphors, or do they refer to deeper, socially embedded forms of perception? This article introduces the concept of “sensing frames”: the socially learned, culturally shaped, and pragmatically enacted modalities through which people perceive and

Ecology and evolution of pyrazines in insects

Biological Reviews, Volume 101, Issue 4, Page 1937-1959, August 2026.
ABSTRACT Chemical communication is the oldest and most widespread form of signalling among and within organisms. Among the many compounds involved in such communication, pyrazines – nitrogen‐containing heterocyclic molecules – are especially intriguing due to their widespread occurrence across the tree of life, from bacteria and fungi to insects and ...

Support for Solitary Bee Conservation among the Public versus Beekeepers

, 2019
© 2019 The Author(s). The decline of European honey bees (Apis mellifera) has been a prominent part of supporting pollinator conservation among the public and conservation efforts, even while honey bees are not native to North America and may compete for

Nectar Robbery by Native and Invasive Bumblebees Reduces Floral Rewards but Not Seed Production in Desfontainia fulgens

Ecology and Evolution, Volume 16, Issue 7, July 2026.
We evaluated nectar robbery by native and invasive bumblebees in the hummingbird‐pollinated shrub Desfontainia fulgens in southern Chile. Nectar robbery strongly reduced nectar standing crop and altered floral visitation patterns, but these proximate effects did not translate into reduced seed production under natural pollination conditions.

Light and Pollination Limitation Alter Patterns of Fitness and Phenotypic Selection in Sagittaria trifolia L.: Insights From Sequential Inflorescences

Ecology and Evolution, Volume 16, Issue 7, July 2026.
We examined how light limitation and reduced pollinator access influence female fitness and phenotypic selection in Sagittaria trifolia across sequential inflorescences. Open‐grown plants produced the most inflorescences, flowers, and seeds, whereas mesh‐enclosed plants compensated for low early fruit set through later reproductive adjustment and ...

Use of Social Bees and Solitary Bees as Bioindicators of Environmental Contamination

International Journal For Multidisciplinary Research
With an emphasis on the biology of bee nesting, their ecological functions, and their efficacy in determining heavy metal pollution, this review paper summarises current research on bees as bioindicators of environmental contamination. Review brought attention to the solitary nesting behaviours of species such as Epanthidium tigrinum and Megachile ...
