Journal of Biogeography, Volume 53, Issue 1, January 2026.ABSTRACT Aim To investigate macroevolutionary and biogeographic patterns of chromosome number variation in ants (Formicidae), and to test whether chromosomal diversity is taxonomically structured, associated with species richness, varies with latitude, and accumulates over evolutionary time. Location Global.

Integrative Conservation, Volume 4, Issue 4, Page 546-554, December 2025.Desertification is increasing in the Brazilian Semiarid, leading to loss of species and ecosystem services, while precise data on biodiversity distribution and trends are lacking. Public engagement in scientific projects can improve ecosystem protection.

Brazilian Journal of Biology, 2004 We examined the spatial implications of maximum flight distance for several species of stingless bees. Data suggested that maximum flight distance in Meliponini is a function of body size, especially generalized wing size, which can be estimated through ...

Recruitment communication in stingless bees (Hymenoptera, Apidae, Meliponini) [PDF]
Apidologie, 2004 The stingless bees (Hymenoptera, Apidae, Meliponini) have evolved sophisticated communication systems that allow foragers to recruit nestmates to good resources. Over the past 50 years, a growing body of research has shown that foragers can communicate three-dimensional resource location, uncovered several potential communication mechanisms, and ...

Insect Conservation and Diversity, Volume 18, Issue 6, Page 1027-1036, November 2025.Both local and landscape factors associated with habitat availability and quality determine the persistence of stingless bees across fragments. Places where the species occurs have local and landscape characteristics distinctive from those where it is absent.

24 million years of pollination interaction between European linden flowers and bumble bees
New Phytologist, Volume 248, Issue 4, Page 2111-2127, November 2025.Summary Pollination is the most common insect–plant mutualism, binding them in a co‐evolutionary framework. Historic evidence of this interaction can be partly inferred from time‐calibrated molecular phylogenies of plant and insect lineages or directly from fossils.

The Life Histories of the "Uruçu Amarela" Males (Melipona flavolineata, Apidae, Meliponini)
Sociobiology, 2018 Here we describe the life histories of adult males of the the Amazonian stingless bee Melipona flavolineata Friese, commonly known as “uruçu amarela”. Males reach sexual maturity inside nests, presenting seminal vesicles full of sperm cells and becoming ...

New occurrence of B chromosomes in Partamona helleri (Friese, 1900) (Hymenoptera, Meliponini) [PDF]
Genetics and Molecular Biology, 2009 Cytogenetic analyses of the stingless bee Partamona helleri collected in the state of Bahia, Northeast Brazil revealed the chromosome numbers n = 18 in the haploid males and 2n = 35 in the diploid females. All karyotypes displayed one large acrocentric B chromosome, which differs from the minute B chromosomes previously described in the populations ...
