Evolutionary convergence on hummingbird pollination in Neotropical Costus provides insight into the causes of pollinator shifts. [PDF]

open access: yesNew Phytol, 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 ...

The importance of pollination and dispersal syndromes for the conservation of Cerrado Rupestre fragments on ironstone outcrops immersed in an agricultural landscape [PDF]

open access: yesNeotropical 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 ...

A geographical perspective on the relationship between Impatiens spur lengths and bill lengths of sunbirds in Afrotropical mountains. [PDF]

open access: yesEcol Evol, 2021
We focused on matching between spur lengths of the genus Impatiens and bill lengths of sunbirds in tropical Africa. For 25 mountain and island locations, we compiled information about the composition and traits of local Impatiens and sunbird assemblages.

Floral resource availability of Dicliptera squarrosa (Acanthaceae) and its dependence on hummingbirds for fruit formation in a forest fragment of Central Brazil [PDF]

open access: yesPlant 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 ...

Reproductive adaptations and the availability of pollinating vectors in white Indian teak (Gmelina arborea Roxb.) in tropical rain forest of Indo-Burma Hotspot

open access: yesTrees, 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-

Nectary structure is not related to pollination system in Trichocereeae cactus from Northwest Argentina

open access: yesAnais da Academia Brasileira de Ciências, 2021
Floral nectaries are essential for plant reproduction but little is known about the relationship between these secretory structures and pollination system in cacti.

Unravelling the mystery of red flowers in the Mediterranean Basin: How to be conspicuous in a place dominated by hymenopteran pollinators

open access: yesFunctional 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.

Global Trends in the Status of Bird and Mammal Pollinators [PDF]

open access: yes, 2015
Biodiversity is declining, with direct and indirect effects on ecosystem func-tions and services that are poorly quantified. Here, we develop the first globalassessment of trends in pollinators, focusing on pollinating birds and mam-mals.

Long‐term progression of inbreeding depression in a Mediterranean ornithophilous shrub

open access: yesPlant Species Biology, Volume 37, Issue 1, Page 103-117, January 2022., 2022
In Anagyris foetida, an ornithophilous Mediterranean species, vegetative and reproductive traits were analyzed in two progenies (selfed and outcrossed) 12 years after transplantation. Levels of inbreeding depression (ID) found were similar to the levels obtained 3 years after transplantation.

Pollination and breeding system of Canna paniculata(Cannaceae) in a montane Atlantic Rainforest: asymmetric dependence on a hermit hummingbird

open access: yesActa 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 ...
