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 ...

Effects of a snowstorm event on the interactions between plants and hummingbirds: fast recovery of spatio-temporal patterns

Revista Mexicana de Biodiversidad, 2011
The global climatic change could cause, in some places, appearance of meteorological phenomena considered rare. If we understand the effect of these phenomena on birds we can understand how birds respond to weather changes. We report here the effect of a

Divergent pollination system and morph-dependent effects of corolla length on inaccuracy of reciprocity and reproductive success of a distylous species of Rubiaceae

Acta Botânica Brasílica, 2021
Intraspecific floral variations may affect the degree of generalization and efficacy of pollinators, with consequences for plant reproductive success.

Structural stability of plant–pollinator interactions despite seasonal abundance of long‐tongued hawkmoths

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.

Heterospecific pollen deposition among plants sharing hummingbird pollinators in the Brazilian Atlantic Forest

Rodriguésia
Hummingbirds are the most important group of pollinating birds in the Neotropics and tend to use, concomitantly, more than one plant species as food source. Pollen may be mixed on hummingbirds' body due to the visits to different plant species; therefore,

Floral trait similarity at the community‐level increases reproductive success suggesting facilitation through pollinator sharing

Oikos, EarlyView.
The ability of plants to attract pollinators is context‐dependent, influenced by floral traits, abundance, and resources from the plant community. Indirect interactions through shared pollinators, from competition to facilitation, may lead to varied reproductive outputs in plants, and the mechanisms behind these interactions remain to be fully ...

Breeding biology and distyly in Palicourea rigida H. B. & K. (Rubiaceae) in the Cerrados of Central Brazil Biologia reprodutiva e distilia em Palicourea rigida H. B. & K. (Rubiaceae) em Cerrados do Brasil Central

Acta Botânica Brasílica, 2010
Distyly is a floral polymorphism more common among the Rubiaceae than in any other angiosperm group. Palicourea rigida is a typically distylous species of the Rubiaceae widely distributed in the Brazilian Cerrados.

Three-Dimensional Kinematics of Hummingbird Flight [PDF]

, 2007
Hummingbirds are specialized for hovering flight, and substantial research has explored this behavior. Forward flight is also important to hummingbirds, but the manner in which they perform forward flight is not well documented.

Individual variation in perceived density of conspecifics and its impacts on the realization of ecological niches

Oikos, EarlyView.
Animals gather information about their surroundings, including their social environment, using a wide range of sensory modalities. Variation in reception, processing and interpretation of information (cues or signals) can lead to differences in how individuals perceive their local environment. Yet, how individual differences in environmental perception
