Journal of Pollination Ecology, 2011 Floral syndromes are traditionally thought to be associated with particular pollinator groups. Ornithophilous flowers tend to have traits that facilitate bird pollination such as having long, narrow, tubular corollas, often vivid coloration and diluted ...

Noûs, EarlyView.ABSTRACT How should we understand the duration of a pleasant or unpleasant sensation, insofar as its duration modulates how good or bad the experience is overall? Given that we seem able to distinguish between subjective and objective duration and that how well or badly someone's life goes is naturally thought of as something to be assessed from her ...

Noûs, EarlyView.ABSTRACT Philosophers often think agency is essentially connected with rationality, intention, or control. However, Minimalists argue that agency is just the power to cause a change; acids and boulders are agents too. Many philosophers treat Minimalism as a wild outlier, assuming its falsity without argument.

Basis of the vocal communication in hummingbirds [PDF]
, 2023 Although hummingbirds draw attention to their unique hovering flight, as other birds, they strongly rely on sounds to communicate. As songbirds and parrots, hummingbirds convergently evolved the capacity of learning how to produce certain vocalizations ...

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 ...

Resilience of floral scent emission after florivory
Plant Biology, EarlyView.Florivory is thought to affect floral traits, impacting pollination. However, our data suggest a stability in post‐florivory scent emission, which may guarantee the maintenance of pollinator visitation regardless of florivory, indicating a resilience of natural systems with multiple and simultaneous interactions. Created in BioRender. Tunes, P.

Botanical Sciences, 2010 We assessed nectar production patterns, the breeding system, and overall pollinator dependence of Psittacanthus schiedeanus (Schlecht. & Cham.) G.Don (Loranthaceae), a mistletoe species that blooms in the late summer of the eastern cloud forests of ...
