Chewing lice (Insecta, Phthiraptera) and feather mites (Acari, Astigmata) associated with birds of the Cerrado in Central Brazil
TLDR
This is the first study of the ectoparasites of wild birds to be conducted in this region of Brazil and new host–parasite associations were registered for two species of chewing lice and for four species of feather mites, thus expanding the geographical distribution in Brazil of six chewing louse species.
Floral preferences of a neotropical stingless bee, Melipona quadrifasciata Lepeletier (Apidae: Meliponina) in an urban forest fragment.
TLDR
Bee abundance at flowers did not significantly correlate to food availability (expressed by flowering plant richness), and a relatively high similarity was found between plant species used by M. quadrifasciata, which was also found in studies carried out in São Paulo State.
Yeast communities associated with stingless bees.
TLDR
The yeast communities associated with the stingless bees Tetragonisca angustula, Melipona quadrifasciata and Frieseomelitta varia were studied, suggesting that a mutually beneficial interaction exists between them.
Diversity of bees and their floral resources at altitudinal areas in the Southern Espinhaço Range, Minas Gerais, Brazil.
TLDR
A one-year inventory of the bee flora and fauna at the quartzitic Ouro Branco Mountains and a two-year survey of the metaliferous Ouro Preto fields found that the southern Espinhaço areas can be given the status of permanent biodiversity preservation area.
Pollen and nectar harvesting by the stingless bee Melipona quadrifasciata anthidioides (Apidae: Meliponini) in an urban forest fragment in Southeastern Brazil
TLDR
Fifty‐five percent of visited plant families overlapped among Parque Estadual da Serra do Rola‐Moça and four other sites in Bahia, São Paulo and Paraná States and abundance of bees was not correlated to food availability.
Starmerella meliponinorum sp. nov., a novel ascomycetous yeast species associated with stingless bees.
TLDR
The sequence of the D1/D2 domains of the large-subunit rDNA showed that the novel species belongs to the Starmerella clade and is most closely related to Candida etchellsii, although the two differ in their sequences by 7% base substitutions.
Philodendron adamantinum (Araceae) lures its single cyclocephaline scarab pollinator with specific dominant floral scent volatiles
TLDR
This work studied the association between Philodendron adamantinum, a species endemic to the Espinhaco Range in Minas Gerais, South-East Brazil, and its exclusive pollinators, and analysed its floral scent composition, and performed field bioassays to verify the scent-mediated attraction of pollinators.
Do ticks and Borrelia burgdorferi s.l. constitute a burden to birds?
TLDR
It was found that infestation by ticks significantly increased heterophyl/lymphocyte ratio in Turdus merula suggesting increased stress, and confirmed Borrelia reservoir hosts may also present symptoms of infection, though these may be subtle.
The traditional knowledge on stingless bees (Apidae: Meliponina) used by the Enawene-Nawe tribe in western Brazil
TLDR
It is concluded that, as an example of other indigenous people, the Enawene-Nawe classify and identify the bees based not only on their structure and morphological aspects but also on the ecological, etiological, and social characteristics of the species.
The value of a tree species (Caryocar brasiliense) for a stingless bee Melipona quadrifasciata quadrifasciata
TLDR
The expansion of crop lands and increased logging for charcoal production in the Brazilian savannahs has reduced richness and abundance of Meliponini bees, but the high availability of nesting substrate did not seem to limit nest density nor cause the clumped pattern of nest distributions found for the study site.
