Nordic Journal of Botany, EarlyView.Pollen limitation, a decrease in seed production due to insufficient pollen receipt, may influence plant demography and the evolution of sexual systems. Its empirical estimation of pollen supplementation of some of the flowers on an individual is well known to be prone to overestimation due to potential resource reallocation among the individual's ...

Is there a diel pattern to nectar secretion in the Red Bloodwood Corymbia gummifera? [PDF]
, 2013 Nectar secretion was measured at 6-h intervals over a 24-h period in flowers of the Red Bloodwood, Corymbia gummifera (family Myrtaceae). Secretion varied among time periods and among trees. There was no clear diurnal or nocturnal pattern.

Generalist‐pollinated Arabis alpina exhibits floral scent variation at multiple scales
Nordic Journal of Botany, EarlyView.Plants that depend on animals for reproduction often use complex floral traits to attract pollinators. Floral scent is recognized as part of the pollinator attraction module and can be shaped by plant‐pollinator interactions. In recent decades, research has started to reveal the dynamic properties of floral scent, identifying patterns of spatial and ...

Nordic Journal of Botany, EarlyView.Passiflora clypeophylla, an endemic species to the Guatemalan karstic forests last seen in 1889 and deemed extinct, was rediscovered in the Department of Alta Verapaz, east of Cobán. The species was known only from a single specimen hailed from the type locality, Rubel Cruz, where it has been found again. An additional location has been identified in a

A taxonomic update of the genus Clavija (Theophrastaceae) in Colombia and Ecuador
Nordic Journal of Botany, EarlyView.Two species of Clavija are described as new to science: C. neivea (Department Huila Colombia), which is similar to C. pungens (Willd. ex Roem. & Schult.) Decne. of coastal Ecuador, but distinguished by its chiefly elliptic leaf blades with less serrate margins and 4‐merous flowers; C. zamorae (Prov.

A contribution to the pollination ecology of Tabebuia pulcherrima (Bignoniaceae) in a sandbank area of the south of Santa Catarina State, Brazil [PDF]
Biotemas, 2004 Studies on pollination mechanisms in Bignoniaceae have show some evidence of co-evolution with its pollen vectors. Floral biology and flower visitors of Tabebuia pulcherrima were investigated in a sandbank area.

Oikos, EarlyView.Seasonal environmental cycles affect plant–pollinator interactions by altering plant phenology. Periods of low resource availability can filter pollinators and reduce the complexity of interaction networks, but the extent to which the functional morphology of pollinators influences such filtering remains unclear.
