Conservation value and permeability of neotropical oil palm landscapes for orchid bees. [PDF]
PLoS ONE, 2013 The proliferation of oil palm plantations has led to dramatic changes in tropical landscapes across the globe. However, relatively little is known about the effects of oil palm expansion on biodiversity, especially in key ecosystem-service providing ...

Long‐term (1979–2019) dynamics of protected orchid bees in Panama
Conservation Science and Practice, 2021 Plants and pollinators are linked but their dynamics are scarcely known. Chemical monitoring of male “orchid bees” at two sites revealed 75% of species were stable or increasing.

Sociobiology, 2019 This work discusses the criteria proposed to consider wild bees as bioindicators and specifically applied to orchid bees in neotropical forests. Some of the issues are: 1) the deficiencies of the sampling methods, which makes it difficult to accurately ...

European Journal of EntomologyBody mass is an important morphological trait, which is associated with the physiology and ecology of insects. In the past, estimates of body mass were often based on general mathematical equations in which body mass was related to linear measurements of

Using ecological niche models and niche analyses to understand speciation patterns: the case of sister neotropical orchid bees. [PDF]
PLoS ONE, 2014 The role of past connections between the two major South American forested biomes on current species distribution has been recognized a long time ago. Climatic oscillations that further separated these biomes have promoted parapatric speciation, in which

Raising the sugar content--orchid bees overcome the constraints of suction feeding through manipulation of nectar and pollen provisions. [PDF]
PLoS ONE, 2014 Unlike most other bees, the long-tongued orchid bees ingest nectar using suction feeding. Although long tongues allow exploitation of flowers with deep spurs, the energy intake rate is optimal at 10-20% lower nectar sugar concentrations compared to that ...

Non-floral scent sources of orchid bees: observations and significance
BiotropicaMales of the neotropical orchid bees collect environmental volatiles to concoct complex species-specific perfumes that are later used in sexual communication. While perfumes are typically seen as being derived from floral sources, these bees also collect

Evidence of introduced honeybees (Apis mellifera) as pollen wasters in orchid pollination [PDF]
Scientific ReportsBiological invasions threaten global biodiversity, altering landscapes, ecosystems, and mutualistic relationships like pollination. Orchids are one of the most threatened plant families, yet the impact of invasive bees on their reproduction remains ...
