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

New Phytol
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 ...

Role of forest edges and other seminatural linear landscape features in structuring wild bee habitat connectivity in intensively managed landscapes. [PDF]

Conserv Biol
Abstract Pollinator conservation schemes typically focus on conserving existing, restoring degraded, or creating new wild bee habitats. Their effectiveness depends on dispersal corridors enabling habitat colonization by bees. However, the role of seminatural linear landscape structures (LLS) in connecting pollinator communities across intensively ...

First large-scale study reveals important losses of managed honey bee and stingless bee colonies in Latin America. [PDF]

Sci Rep
Over the last quarter century, increasing honey bee colony losses motivated standardized large-scale surveys of managed honey bees (Apis mellifera), particularly in Europe and the United States.

Bee Body Size and Foraging Behavior Predict the Pollination Role of Bees in a Buzz-Pollinated Plant Community. [PDF]

Ecol Evol
We investigated how bee traits influence pollination success in a buzz‐pollinated plant community. Larger body size and floral sonication strongly predicted stigma contact, a proxy for pollination efficiency, while longer handling times were associated with reduced effectiveness.
