Eschweilera nana is pollinated by a guild of pollinators consisting of mostly bees. Effective pollinators are large bees able to force their way into the closed androecium to access nectar. The morphology of the flowers diminishes self pollination and promotes cross-pollination. Although many pollinators make diurnal visits to the flowers, fruit set was very low in comparison with the number of flowers produced. Breeding system tests yielded only two fruits, one produced by xenogamy and another… 
Nectar production dynamics and daily pattern of pollinator visits in Brazil nut (Bertholletia excelsa Bonpl.) plantations in Central Amazon: implications for fruit production
TLDR
In the large-scale Brazil nut tree plantation studied here, where genetically identical individuals are planted together in high densities, even where bees move between trees, they seem to promote functional geitonogamy, determining pollen limitation.
Buds, Bugs and Bienniality: The Floral Biology of Eschweilera tenuifolia (O. Berg) Miers in a Black-Water Flooded Forest, Central Amazonia
TLDR
Insect infestation of buds can play an important role in regulating flower:fruit ratios, thus setting limits on individual total seed set, and biennial flowering in E. tenuifolia is likely to be an energy-conserving response in a highly physiologically-challenging environment.
Floral characteristics support nocturnal pollination and pollination syndrome in Barringtonia racemosa
To test for pollination syndrome and to complement records of foraging visitors of an associate mangrove, Barringtonia racemosa (L.) Spreng., aspects of its floral biology were investigated.
Nectar features, diurnal and nocturnal pollinators, and male fitness in Qualea grandiflora (Vochysiaceae)
TLDR
Pollination system of Qualea grandiflora, the most widespread woody species of Cerrado, the Neotropical savannas in Central Brazil, is investigated, focusing on nectar features, their relationship with nocturnal and diurnal pollinators and how nectar affects male fitness, measured through pollen removal.
The influence of El Niño and edge effects on the reproductive phenology and floral visitors of Eschweilera tetrapetala Mori (Lecythidaceae), an endemic species of the Atlantic Forest of northeastern Brazil
We compared the reproductive phenology and fl oral visitors of Eschweilera tetrapetala growing along the edge and in the interior of a submontane forest in the Chapada Diamantina mountains, Bahia
Paliurus Fruits from the Oligocene of South China and Their Phytogeographic Implications
TLDR
The discovery of the first P. favonii fossil described with detailed cuticular characteristics from China demonstrates that the genus existed in the Oligocene Ningming region, South China, and provides new information for understanding the fossil history.
Annotated catalog and bibliography of the cyclocephaline scarab beetles (Coleoptera, Scarabaeidae, Dynastinae, Cyclocephalini)
TLDR
This paper discusses the history of cataloging dynastine species, clarifies issues surrounding the neotype designations in Endrődi’s revision of Cyclocephalini, synthesizes all published distribution data for cyclocephaline species, and increases accessibility to the voluminous literature on the group by providing an easily searchable bibliography for each species.
How (much) do flowers vary? Unbalanced disparity among flower functional modules and a mosaic pattern of morphospace occupation in the order Ericales
TLDR
It is found that the floral morphospace is organized as a continuous cloud in which most clades occupy distinct regions in a mosaic pattern, that disparity increases with clade size rather than age, and that fossils fall in a narrow portion of the space.

Some pollination strategies in neotropical savannas and forests
  • G. Gottsberger
  • Environmental Science
    Plant Systematics and Evolution
  • 2004
TLDR
Evaluated trends of pollination strategies in neotropical savannas and forests suggest parallel modifications of the basic ornithophilous flower principle can be traced in different groups of theMalvaceae.
The Pollination and Androphore Structure of Some Amazonian Lecythidaceae
TLDR
The complex androphore structure of the Lecythidaceae is concluded to have evolved to protect the fertile stamens and to increase efficiency of pollination rather than as an adaptation to new pollinators.
Biología reproductiva de Eschweilera bogotensis (Lecythidaceae), en la Cordillera Occidental de Colombia
TLDR
Bites on the fruits observed in the field suggest that the disperser is a rodent, probably a squirrel, common at the study site, and Seed dispersal by animals, which eat part of the peel and seeds, is significant.
Pollination of two species of Vellozia (Velloziaceae) from high-altitude quartzitic grasslands, Brazil
TLDR
Low natural seed production compared to cross-pollination seed numbers suggests that pollen limitation is the main cause of low seed set of Vellozia leptopetala.

Observations on flower visitors to Bertholletia excelsa H.B.K. and Couratari tenuicarpa A.C. Sm. (Lecythidaceae)
TLDR
Pollen analysis indicated that all bees captured carried pollen of the host tree in question and had been foraging on flowers of plant species common in secondary growth near the Aleixo plantation.
