Physiological Entomology, EarlyView.The Lauxaniid fly Incurviseta cf. maculifrons (Malloch, 1925) is a locally abundant but poorly understood flower visitor in the Australian Alpine. We describe the flower visitation, pollen transport, pollen diet and mouthpart morphology of I. cf. maculifrons using field observations, pollen analyses and scanning electron microscopy. I. cf.

Genetic interactions among floral homeotic genes of Arabidopsis [PDF]
, 1991 We describe allelic series for three loci, mutations in which result in homeotic conversions in two adjacent whorls in the Arabidopsis thaliana flower. Both the structure of the mature flower and its development from the initial primordium are described ...

Plant Biology, EarlyView.Drought stress leads to reduced nectar secretion and alters nectar composition of day‐ and night‐flowering Nicotiana species, which may impair plant–pollinator interactions. Abstract The frequencies of droughts worldwide will increase in the future due to climate changes. Nectar composition of plant species varies in relation to pollinator and can also

Where is the reward? Floral nectaries in Aspidosperma australe flowers [PDF]
RodriguésiaNectaries are secretory structures that produce a solution rich in sugars, which are involved in animal-plant interactions. Such secretory structures can be externally distinguishable (recognizable), as in glands or discs, or not, as in some gynoecial ...

Plant Biology, EarlyView.Drought duration affects ant–plant interactions: extrafloral nectar quality initially increases and subsequently declines, and ant interaction patterns closely track these nectar dynamics. Abstract Mutualistic plants use non‐structural sugar (NSC) to produce carbon‐based resources to reward partners.

Extrafloral-nectar based partner manipulation in plant-ant relationship [PDF]
, 2015 Plant–ant interactions are generally considered as mutualisms, with both parties gaining benefits from the association. It has recently emerged that some of these mutualistic associations have, however, evolved towards other forms of relationships and,

Taxonomy and diversity of Marcgraviaceae, north of the São Francisco river, northeast Brazil
Nordic Journal of Botany, Volume 2026, Issue 4, April 2026.This study provides a comprehensive assessment of Marcgraviaceae species diversity north of the São Francisco river in northeastern Brazil, analyzing species richness and distribution patterns across 384 000 km² of phytogeographic domains. Through field collections, herbarium studies (both physical and digital), and detailed morphological analyses, we ...
