The importance of pollination and dispersal syndromes for the conservation of Cerrado Rupestre fragments on ironstone outcrops immersed in an agricultural landscape [PDF]
Neotropical Biology and Conservation, 2022 Studies on pollination and seed dispersal are essential for the conservation of plant diversity. In this study, we aimed to evaluate the pollination and dispersal syndromes of five fragments of the Cerrado Rupestre immersed in an agricultural landscape ...

Floral resource availability of Dicliptera squarrosa (Acanthaceae) and its dependence on hummingbirds for fruit formation in a forest fragment of Central Brazil [PDF]
Plant Ecology and Evolution, 2019 Background and aims – Hummingbirds are dependent and specialized on nectar-feeding, and many plants depend upon them for pollination. However, the degree of plant-pollinator interdependence varies greatly among species; thus, information on plant mating ...

Trees, Forests and People, 2021 For the effective management of economically and ecologically valuable tree species, it is crucial to understand pollination and resource allocation particularly in biotic pollinated species. Gmelina arborea Roxb. growing in moist tropical forest of Indo-

Ecosphere, Volume 14, Issue 11, November 2023., 2023 Abstract Nectar robbers and thieves are common antagonists in plant–pollinator communities, where they deplete nectar without pollinating flowers, substantially affecting plant reproduction. Nevertheless, little is known about the relative abundance of such nectar exploiters in communities, even though spatiotemporal changes in the frequencies of ...

Functional Ecology, Volume 36, Issue 11, Page 2774-2790, November 2022., 2022 Read the free Plain Language Summary for this article on the Journal blog. Abstract Red‐flowered species have traditionally been related to ornithophily, and the ‘bee avoidance’ hypothesis, that is, red flower colouration is a way to reduce visits from hymenopterans, has been proposed to explain this association.

New Phytologist, Volume 236, Issue 4, Page 1572-1583, November 2022., 2022 Summary The evolution of hummingbird pollination is common across angiosperms throughout the Americas, presenting an opportunity to examine convergence in both traits and environments to better understand how complex phenotypes arise. Here we examine independent shifts from bee to hummingbird pollination in the Neotropical spiral gingers (Costus) and ...

Acta Botânica Brasílica, 2015 We studied the pollination biology of Canna paniculata (Cannaceae), a plant species common in the Atlantic Rainforest of southeastern Brazil. The species presents specialized ornithophilous flowers, which in our study area are solely pollinated by the ...

Nectary structure of Ornithidium sophronitis Rchb.F. (Orchidaceae: Maxillariinae)
Acta Agrobotanica, 2012 Most orchids do not produce floral food-rewards. Instead, they attract pollinators by mimicry or deceit. When present, the most common floral food-reward is nectar.
