Inflorescence and floral traits of the Colombian species of Tristerix (Loranthaceae) related to hummingbird pollination

open access: yesAnales del Jardín Botánico de Madrid, 2017
Floral diversification in Loranthaceae reaches its highest peak in the Andes. The flowers of the exclusively Andean genus Tristerix exhibit tubular and vividly coloured flowers pollinated by hummingbirds. We studied inflorescence and flower morphoanatomy

Influence of floral orientation on feeding behavior in Anna's hummingbirds

open access: yesJournal of Avian Biology, Volume 2025, Issue 3, May 2025.
Hover‐feeding by hummingbirds from pendent flowers relative to horizontal flowers increases the metabolic cost of flight, but in nature a large proportion of hummingbird‐pollinated flowers are nonetheless oriented near‐vertically downward. We used binary‐choice tests to assess behavioral preference of captive Anna's hummingbirds for these two ...

Geographic and Biological Drivers Shape Anthropogenic Extinctions in the Macaronesian Vascular Flora

open access: yesGlobal Change Biology, Volume 31, Issue 2, February 2025.
The anthropogenic extinction patterns and processes of the vascular flora in the model island region of Macaronesia have been investigated in the present study. We compiled all known extinction records, both at global and local scales, across the five archipelagos comprising the region (Azores, Madeira, Salvajes, Canary Islands, and Cabo Verde).

Pollination research in India: Current status, future vision and conservation implications 印度的传粉研究现状、愿景与保护启示

open access: yesIntegrative Conservation, Volume 3, Issue 4, Page 330-341, December 2024.
Despite the availability of data on plants and their pollinators from the Indian sub‐continent, detailed investigations that explain the intricacy of the mutualistic interaction at both population and community levels have largely been limited. This review explores the current status of pollination ecology research in India and suggests future ...

Ratio changes in blood‐feeding and voltinism in black flies (Diptera: Simuliidae) over a latitudinal gradient in North America north of Mexico

open access: yesMedical and Veterinary Entomology, Volume 38, Issue 4, Page 566-572, December 2024.
Female simuliid species traits of voltinism and feeding produce 5 two‐trait states: non‐feeding/univoltine, ornithophilic/univoltine, mammalophilic/univoltine, ornithophilic/multivoltine, mammalophilic/multivoltine. We examined latitudinal variation in each two‐trait state using three large databases.

Ornithophily in the genus Salvia L. (Lamiaceae)

open access: yes, 2007
This dissertation presents for the first time a survey of bird pollinated (ornithophilous) Salvia species. Within the approximately 1000 species of the worldwide distributed genus roughly 20% (186 spp.) are bird pollinated. Excepting four species in the Old World (South Africa and Madagascar), ornithophilous species are restricted to the New World ...

Floral Visitors and Florivory in Tacinga inamoena (Cactaceae) in the Ex Situ Collection of the Rio de Janeiro Botanical Garden

open access: yesJournal of Zoological and Botanical Gardens
Tacinga inamoena (K. Schum.) N.P. Taylor & Stuppy (Cactaceae, Opuntioideae) is a native Brazilian species found in the Caatinga phytogeographic domain. Although its flowers are adapted for bird pollination (ornithophily), few birds visit these plants in ...
