Pollination Syndromes in Mediterranean Orchids—Implications for Speciation, Taxonomy and Conservation [PDF]

open access: yes, 2018
The Mediterranean flora is spectacularly rich in orchid species that have evolved remarkable adaptations to their environment. Orchids have complex and delicate interactions with their pollinators, which makes them particularly prone to local extinction.

Pollinator‐dependence and specialization in three sunbird‐pollinated, fire‐stimulated flowering species

open access: yesPlant Biology, Volume 28, Issue 1, Page 215-224, January 2026.
Through field observations and experimental verification, we found that three bird‐pollinated plant species with fire‐stimulated flowering specialize in, and heavily depend on, sunbirds for pollination and reproduction. Abstract Fires dramatically reduce both floral resources and pollinator abundance, potentially compromising flowering plant ...

Methodological concerns and challenges in ecological studies with orchid bees (Hymenoptera: Apidae: Euglossina)

open access: yesBioscience Journal, 2012
The Neotropical orchid bees have been the focus of several ecological studies in the last four decades, mainly due to the ease of attracting males of their species to synthetic baits that simulate floral fragrances.

Low heat tolerance and high desiccation resistance in nocturnal bees and the implications for nocturnal pollination under climate change

open access: yesScientific Reports, 2023
Predicting insect responses to climate change is essential for preserving ecosystem services and biodiversity. Due to high daytime temperatures and low humidity levels, nocturnal insects are expected to have lower heat and desiccation tolerance compared ...

Thermal stability and muscle efficiency in hovering orchid bees (Apidae:Euglossini) [PDF]

open access: yesJournal of Experimental Biology, 2004
SUMMARYTo test whether variation in muscle efficiency contributes to thermal stability during flight in the orchid bee, Euglossa imperialis, we measured CO2 production, heat loss and flight kinematics at different air temperatures (Ta). We also examined the relationship between wingbeat frequency (WBF) and Ta in five additional species of orchid bees ...

Mimics and magnets : The importance of color and ecological facilitation in floral deception [PDF]

open access: yes, 2008
Plants that lack floral rewards can attract pollinators if they share attractive floral signals with rewarding plants. These deceptive plants should benefit from flowering in close proximity to such rewarding plants, because pollinators are locally ...

Ecological Interactions of the Sexually Deceptive Orchid Orchis Galilaea [PDF]

open access: yes, 2018
Plant species dependent on highly specific interactions with pollinators are vulnerable to environmental change. Conservation strategies therefore require a detailed understanding of pollination ecology.

Pollination ecology in the tropical Andes: moving towards a cross‐scale approach

open access: yesBiological Reviews, Volume 100, Issue 6, Page 2312-2345, December 2025.
ABSTRACT Plant–pollinator interactions structure ecological communities and represent a key component of ecosystem functioning. Pollination networks are expected to be more diverse and specialised in the tropics, but pollination ecology in these regions has been understudied in comparison to other areas.

Orchid bees as bio-indicators for organic coffee farms in Costa Rica: Does farm size affect their abundance?

open access: yesRevista de Biología Tropical, 2006
The potential of Euglossini bees, especially Euglossa, as biological indicators of organic vs non-organic coffee farms was studied in Atenas and San Isidro, Alajuela, Costa Rica using 1.8-cineole as lure.

Are orchid bees at risk? First comparative survey suggests declining populations of forest-dependent species

open access: yesBrazilian Journal of Biology
The two largest Atlantic Forest remnants in the state of Espírito Santo, eastern Brazil, namely ‘Reserva Biológica de Sooretama’ (REBIO Sooretama) and ‘Reserva Natural Vale’ (RNV), were surveyed for their orchid-bee faunas.
