Is the pollination efficiency of long-lived orchid flowers affected by age?
Revista Ceres, 2015 The long-lived flowers of orchids increase the chances of pollination and thus the reproductive success of the species. However, a question arises: does the efficiency of pollination, expressed by fruit set, vary with the flower age?

What climate adaptation can learn from evolutionary adaptation
Conservation Biology, EarlyView.Abstract Evolutionary and climate adaptation both describe how complex systems respond to environmental change, either via natural selection or deliberate human choices. Although adaptation in both contexts is expected to produce favorable outcomes, it can also result in maladaptation—ineffective, unintended, or harmful outcomes. As an emerging area of

Biologia floral e polinização por abelhas em siratro (Macroptilium atropurpureum Urb.)
Acta Scientiarum: Animal Sciences, 2008 Cette recherche a été réalisée pour évaluer la pollinisation chez le siratro en étudiant la période d'anthèse, la viabilité des grains de pollen et la production de graines. Deux traitements ont été utilisés, l'un couvert et l'autre découvert. La période d'anthèse était de 2,48 jours et de 3,56 jours (p = 0,0001) et la production était de 8,62 et 11,15

Impact of climate on the migration phenology of the endangered Little Bustard in Spain
Ibis, EarlyView.The phenology of animals is closely tied to seasonal climatic patterns so, by altering temperature and precipitation regimes, climate change disrupts the phenological cycles of species. More specifically, the influence of rising temperatures on the phenology of bird migration has been long studied.

Fly me to the canopy: Diptera communities in oak forest crowns as bioindicators of stand decline
Insect Conservation and Diversity, EarlyView.Diptera diversity: Oak decline increases the overall Diptera diversity, particularly in saproxylic and floricolous guilds, likely due to more open canopies and greater deadwood and floral resource availability. Family responses: Dolichopodidae, Empididae, Hybotidae and Anthomyiidae thrive in declining stands, whereas Mycetophilidae and other fungus ...

Biologia floral de Cleistes macrantha (Barb. Rodr.) Schltr. (Orchidaceae: Vanilloideae: Pogoniinae) [PDF]
Revista Brasileira de Botânica, 2003 Cleistes macrantha (Barb. Rodr.) Schltr. is widely distributed in Atlantic rain forests in south and southeastern Brazil, occurring in anthropogenic disturbed areas and in "restinga" vegetation. Aspects of the floral biology of C. macrantha were investigated in the Intervales nature reserve, in the interior of Sao Paulo state.
