Manipulation of carbohydrate diet and ensuing changes in weight and glycogen storage in bumble bee (Bombus impatiens) queens [PDF]

open access: yes, 2014
Bumble bees serve as important pollinators for human crops, but many of their populations have declined over the past 60 years. Bumble bee population decline is very important for humans because it reduces pollination services, which can lead to lower ...

Variability in Floral Scent in Rewarding and Deceptive Orchids: The Signature of Pollinator-imposed Selection? [PDF]

open access: yes, 2017
Background and Aims A comparative investigation was made of floral scent variation in the closely related, food-rewarding Anacamptis coriophora and the food-deceptive Anacamptis morio in order to identify patterns of variability of odour compounds in the

Experimental investigation of the effect of spatial aggregation on reproductive success in a rewardless orchid [PDF]

open access: yes, 2018
Plant reproductive success within a patch may depend on plant aggregation through pollinator attraction. For rewardless plants that lack rewards for pollinators, reproductive success may rely strongly on the learning abilities of pollinators.

Non-floral scent sources of orchid bees [PDF]

open access: yes
Observamos abejas euglosinas macho recolectando fragancias en 21 fuentes no florales en Centro y Sudamérica, lo que refuerza la hipótesis que estas fuentes desempeñan un papel importante en la biología de los perfumes de las abejas euglosinas. Un árbol de \(\it Protium\) proporcionó más del 50% de los perfumes para \(\textit {Eufriesea corusca}\) y fue

Orchid bee (Hymenoptera: Apidae) community from a gallery forest in the Brazilian Cerrado

open access: yesRevista de Biología Tropical, 2012
The orchid bees are a very important group of pollinators distributed in the Neotropics. Although a lot of studies concerning male euglossine bees have been done in this region, few works have so far been carried out in the Cerrado biome. This manuscript
