Chalepogenus roitmani Roig Alsina (Hymenoptera: Apidae: Tapinotaspidini): description of the male and new geographical records for the species
(Magnolia Press, 2011)
Bees of the genus Chalepogenus Holmberg collect oils offered as a reward by flowers of a few plant families: Iridaceae, Calceolariaceae (formerly included in Scrophulariaceae, see Olmstead et al. 2001), and Solanaceae ...
Oil-producing flowers of Sisyrinchium species (Iridaceae) and their pollinators in southern South America
(Elsevier Gmbh, 2001-12)
The floral relationships existing between the mainly New World genus Sisyrinchium (Iridaceae) and oil-collecting bees were investigated in southern South America. In addition to a single species known before as producing ...
New insights into the phylogenetic relationships, character evolution, and phytogeographic patterns of Calceolaria (Calceolariaceae)
(Botanical Society of America, 2009-12)
Biogeographical patterns and diversification processes in Andean and Patagonian flora are not yet well understood. Calceolaria is a highly diversified genus of these areas, representing one of the most specialized plant - ...
Teasing out the functional groups of oil-collecting bees in the light of the pollination of Nierembergia flowers
(Springer, 2021-08)
Pollination interactions between plants bearing oil-flowers and oil-collecting bees are regarded as specialized, and within the major group of bees,oil-collecting bees are considered a special functional group of pollinators, ...
Do 120,000 years of plant–pollinator interactions predict floral phenotype divergence in Calceolaria polyrhiza? A reconstruction using species distribution models
(Springer, 2016-12)
Quaternary climatic changes impacted species demography and distribution worldwide. Although response to climate change could have been modulated by mutualistic interactions with other species, studies exploring the dynamics ...
Specialisation in pollen collection, pollination interactions and phenotypic variation of the oil-collecting bee Chalepogenus cocuccii
(EDP Sciences, 2020-04)
Bee pollen gathering from a few related plant species is a specialisation known as oligolecty. Although it is an extended phenomenon, it has been scarcely explored in oil-collecting bees. At the geographic level, there is ...
Sistemática do gênero Lanthanomelissa Holmberg (Hymenoptera, Apidae: Tapinotaspidini)
(2017-04-18)
O gênero Lanthanomelissa Holmberg, 1903 é representado por abelhas pequenas com distribuição restrita as áreas de campos do sul e sudeste do Brasil, do Paraguai e da Argentina. Descrito por Holmberg em 1903, o grupo apresenta ...
Pollination syndromes in a specialised plant-pollinator interaction: does floral morphology predict pollinators in Calceolaria?
(Wiley, 2015)
Pollination syndromes are defined as suites of floral traits evolved in response to selection
imposed by a particular group of pollinators (e.g., butterflies, hummingbirds,
bats). Although numerous studies demonstrated ...
