Variation in plant-animal interactions along an elevational gradient of moist forest in a semiarid area of Brazil

Acta Botânica Brasílica, 2016
Pollination and dispersal are critical ecological processes that directly affect the reproductive success of plants and are important for understanding the structure of plant communities.

Preliminary studies on ornithophilous floral visitors in the Australian endemic Passiflora herbertiana Ker Gawl. (Passifloraceae)

Journal of Pollination Ecology, 2015
The pollination biology of the Australian endemic species Passiflora herbertiana (Passiflora subgenus Decaloba, supersection Disemma, section Disemma) was investigated in a single population growing in the Witches Falls section of Mount Tamborine ...

Molecular phylogenetics clarifies generic boundaries of the papilionoid legume subtribe Clitoriinae

TAXON, Volume 75, Issue 3, June 2026.
Abstract Clitoriinae is a morphologically distinctive and pantropically distributed subtribe within the legume tribe Phaseoleae (Leguminosae, Papilionoideae), yet its genus‐level taxonomic classification remains uncertain. This study presents the most comprehensive phylogenetic analysis of Clitoriinae to date, integrating plastid (matK/trnK) and ...

Autogamy vs. Allogamy: Biotic-Dependent Populations Reveal Shift in the Reproduction System of an Essentially Autogamous Vanilla

Diversity
Flowering plants have evolved a wide range of strategies to avoid self-fertilization. Although allogamy is common among members of the genus Vanilla, V. lindmaniana is widely known for its ability to self-fertilize, resulting in fruit-set rates of 83–100%

Seasonal and Within‐Day Variation on Hummingbirds Visits and Dominance Hierarchy in a Brazilian Cerrado Area

Austral Ecology, Volume 51, Issue 3, March 2026.
ABSTRACT Plant‐hummingbird interaction networks can be influenced by environmental conditions and resources, which vary seasonally and daily. We aimed to understand how variations in these parameters across these two temporal windows influence patterns of plant‐hummingbird interactions and hummingbirds dominance hierarchies in a Brazilian Cerrado ...

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

Anales 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

Pollination Beyond the Usual Suspects: Endemic Neodrepanis coruscans Birds Visiting Tubular Flowers in Madagascar

African Journal of Ecology, Volume 63, Issue 4, June 2025.
ABSTRACT Bird pollination remains understudied in Madagascar. We document the first recorded observation of common sunbird‐asity Neodrepanis coruscans (Philepittidae), a Malagasy endemic which is not a true sunbird, visiting and potentially pollinating Bakerella clavata, a plant with long tubular flowers.

Síndromes de polinização e de dispersão em fragmentos da Floresta Estacional Semidecídua Montana, SP, Brasil Pollination and dispersal syndromes in semideciduous montane forest fragments, São Paulo State, Brazil

Acta Botânica Brasílica, 2007
Este estudo teve como objetivo conhecer a distribuição de síndromes de polinização e dispersão entre os estratos verticais e entre a borda e o interior de fragmentos da Floresta Estacional Semidecídua Montana, na Fazenda Bela Vista (46º52'W e 22º47'S ...

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

Journal 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

Global 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).
