1. Moths (L epidoptera) are the major nocturnal pollinators of flowers. However, their
importance and contribution to the provision of pollination ecosystem services may have …

Caesalpinia echinata (brazilwood) is a threatened tree endemic to the Brazilian Atlantic
forest with a global importance as it is worldwide used to manufacture the most desirable …

The evolution of floral traits is often considered to reflect selection for increased pollination
efficiency. Known as the pollination‐precision hypothesis, increased pollination efficiency is …

Corolla shape is one of many floral traits used by pollinators when making foraging
decisions. Corolla shape has been implicated as a factor in floral isolation and evolutionary …

Scent glands, or osmophores, are predominantly floral secretory structures that secrete
volatile substances during anthesis, and therefore act in interactions with pollinators. The …

Background and aims A South American cactus species, Echinopsis ancistrophora
(Cactaceae), with dramatic among-population variation in floral traits is presented. Methods …

Variation in floral phenotype (color, depth, nectar) suggests incipient specialization for bee
or hawkmoth pollination across the geographic distribution of Echinopsis ancistrophora, with …

Circadian patterns of activity are considered ubiquitous and adaptive, and are often invoked
as a mechanism for temporal niche partitioning. Yet, comparisons of rhythmic behavior in …

The aim of this study was to analyse the reproductive biology of Echinopsis terscheckii, a
species endemic to northwest Argentina that has nocturnal flowers. We expected that this …

Biotic and abiotic context may affect the intensity of interspecific interactions and
subsequently drive locally particular phenotypic selection patterns on interacting traits. We …
