Flowering cycles of woody bamboos native to southern South America
(Springer Tokyo, 2014-03)
Neotropical woody bamboos range from northern Mexico to southern Argentina and Chile. The most interesting aspect of bamboo biology is their flowering habit. The species that are the most intriguing are those that manifest ...
Flowering Phenology and the Influence of Seasonality in Flower Conspicuousness for Bees
(2021-02-16)
Flowering patterns are crucial to understand the dynamics of plant reproduction and resource availability for pollinators. Seasonal climate constrains flower and leaf phenology, where leaf and flower colors likely differ ...
And after fire, the Cerrado flowers: A review of post-fire flowering in a tropical savanna
(2021-07-01)
Post-fire flowering is a fire-adaptive trait that is underused in fire ecology literature to describe plant responses to fire. Most of the species described so far as having this strategy occur in mediterranean vegetation, ...
Floral anatomy of Paepalanthoideae (Eriocaulaceae, Poales) and their nectariferous structures
(2007-01-01)
• Background and Aims: Eriocaulaceae (Poales) is currently divided in two subfamilies: Eriocauloideae, which comprises two genera and Paepalanthoideae, with nine genera. The floral anatomy of Actinocephalus polyanthus, ...
Nectar Replaced by Volatile Secretion: A Potential New Role for Nectarless Flowers in a Bee-Pollinated Plant Species
(Frontiers Media Sa, 2018-09-05)
The presence of nectarless flowers in nectariferous plants is a widespread phenomenon in angiosperms. However, the frequency and distribution of nectarless flowers in natural populations, and the transition from nectariferous ...
Does fire induce flowering in Brazilian subtropical grasslands?
(Wiley-Blackwell, 2014-10-01)
QuestionsWe aimed to analyse the effect of fire on flowering in subtropical grasslands, by addressing the following questions: will fire history affect flowering? If yes, do fire feedbacks influence flowering or is it just ...
Directional selection for flowering time leads to adaptive evolution in Raphanus raphanistrum (Wild radish)
(Wiley Blackwell Publishing, Inc, 2016-04)
Herbicides have been the primary tool for controlling large populations of yield depleting weeds from agro-ecosystems, resulting in the evolution of widespread herbicide resistance. In response, nonherbicidal techniques ...
Phoretic dispersal on bumblebees by bromeliad flower mites (Mesostigmata, Melicharidae)
(Springer Basel Ag, 2012-02-01)
Nectarivorous flower mites (Mesostigmata: Melicharidae) live mostly on hummingbird-pollinated plants in the New World. We observed Proctolaelaps sp. living on Neoregelia johannis (Bromeliaceae) in a coastal rain forest ...
Flowering phenology adjustment and flower longevity in a South American alpine species
(MDPI, 2021)
Delayed flowering due to later snowmelt and colder temperatures at higher elevations in the alpine are expected to lead to flowering phenological adjustment to prevent decoupling of peak flowering from the warmest time of ...
Phenological aspects of flowering and fruiting at the Ecological Station of Paulo de Faria-SP-Brazil
(1997-12-01)
The present work was carried out at 'Estacao Ecologica de Paulo de Faria', north of the state of Sao Paulo, southeast of Brazil (19°55'-19°58'S and 49°31'-49°32'W). The flowering and fruiting phenology of trees, shrubs, ...
