Chemical niche differentiation among sympatric species of orchid bees [PDF]

Ecology, 2009
Male Neotropical orchid bees (Euglossini) collect volatile substances (fragrances) from flowers and other sources (e.g., decaying wood) and store them in specialized hind tibial pockets. The accumulated chemicals are later emitted during courtship display, presumably to lure conspecific females for mating.

Deforestation narrows pollen diet diversity of generalist orchid bees

Journal of Insect Conservation
Orchid bee species are important pollinators in the Neotropics. While male orchid bees are known to have a close interaction with odor-rewarding flowers, orchid bee females are often pollen generalists.

Rediscovery of Passiflora clypeophylla (subgenus Decaloba): a highly threatened and narrow endemic species found within a karstic canyon in Guatemala

Nordic Journal of Botany, EarlyView.
Passiflora clypeophylla, an endemic species to the Guatemalan karstic forests last seen in 1889 and deemed extinct, was rediscovered in the Department of Alta Verapaz, east of Cobán. The species was known only from a single specimen hailed from the type locality, Rubel Cruz, where it has been found again. An additional location has been identified in a

Convergent evolution of floral signals underlies the success of Neotropical orchids [PDF]

, 2013
The great majority of plant species in the tropics require animals to achieve pollination, but the exact role of floral signals in attraction of animal pollinators is often debated.

Animating blossom: Time‐lapse to encourage plant awareness in the YouTube era

PLANTS, PEOPLE, PLANET, EarlyView.
Time‐lapse videos can effectively capture key traits of flower blossoms, such as color, 3D structure, and temporal changes, making them valuable complements to herbarium specimens and other botanical collections. Despite the abundance of such videos on YouTube, most provide no ecological and botanical insights.

More than symbioses : orchid ecology ; with examples from the Sydney Region [PDF]

, 2013
The Orchidaceae are one of the largest and most diverse families of flowering plants. Orchids grow as terrestrial, lithophytic, epiphytic or climbing herbs but most orchids native to the Sydney Region can be placed in one of two categories.

Diverse pollination systems of the twin-spurred orchid genus Satyrium in African grasslands [PDF]

, 2013
The large terrestrial orchid genus Satyrium underwent evolutionary radiations in the Cape floral region and the grasslands of southern and eastern Africa. These radiations were accompanied by tremendous diversification of the unusual twin-spurred flowers

Pollination‐related plant traits under environmental changes: Seasonal and daily mismatches produce temporal constraints

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Pollination is a key tenet of ecosystem sustainability and food security, but it is threatened by climate change. While many studies investigated the response of plant‐pollination traits to temperature, few attempted multifactorial and integrative approaches with ...

Sympatric Speciation: Perfume Preferences of Orchid Bee Lineages [PDF]

Current Biology, 2008
Female attraction to an environmentally derived mating signal released by male orchid bees may be tightly linked to shared olfactory preferences of both sexes. A change in perfume preference may have led to divergence of two morphologically distinct lineages.
