Diversity and Distributions, Volume 31, Issue 10, October 2025.ABSTRACT Aim The distribution of species relying on mutualistic partners for reproduction can be constrained by their partners' distribution. Nonetheless, biotic interactions are often overlooked when estimating the distributions of species (e.g., pollinators of a given plant and the proportion of them with their distribution modelled). In the Tropics,

Observations on fragrance collection behaviour of euglossine bees (Hymenoptera, Apidae)
Revista Brasileira de Entomologia, 2015 AbstractMale bees of the tribe Euglossini collect volatile chemicals secreted by orchids using dense patches of hair on the front tarsi. After collecting chemicals, the bee hovers while transferring these fragrances to invaginations on the hind tibiae. The fragrance collection and hovering behaviours are repeated multiple times.

More than fruity scents: Pollination biology, scent, and spectral reflectance of Annonaceae species
Plant Species Biology, Volume 40, Issue 5, Page 403-425, September 2025.We characterised the floral visual and olfactory cues of numerous Annonaceae species and reported their pollinators. We further assessed the olfactory space of most Annonaceae species available in the literature. Abstract The family Annonaceae possesses a broad array of floral phenotypes and pollination specializations, and are important in the plant ...

A strong immune response in young adult honeybees masks their increased susceptibility to infection compared to older bees [PDF]
, 2012 Honeybees, Apis mellifera, show age-related division of labor in which young adults perform maintenance ("housekeeping") tasks inside the colony before switching to outside foraging at approximately 23 days old. Disease resistance is an important feature

Functional Ecology, Volume 39, Issue 7, Page 1786-1798, July 2025.Read the free Plain Language Summary for this article on the Journal blog. Abstract Campanula flowers (Campanulaceae) are visited by generalist and specialist bees of different families. While generalists rely on common volatiles within the floral scent of Campanula, specialist Megachilidae mainly use unusual spiroacetals for host flower recognition ...

Hair‐based minimally invasive barcoding of bumblebees
Insect Conservation and Diversity, Volume 18, Issue 2, Page 127-139, March 2025.We investigated a minimally invasive sampling method for barcoding bumblebees based on hair. The method was tested with commercially reared specimens, older collection material and field‐caught animals. Barcoding success depends on sample origin—commercially reared and frozen collection samples yielded the best results. Wild‐caught animals' species (88%

Is the “Centro de Endemismo Pernambuco” a biodiversity hotspot for orchid bees?
Brazilian Journal of BiologyThe orchid-bee faunas (Hymenoptera: Apidae: Euglossina) of the three largest forest remnants in the “Centro de Endemismo Pernambuco”, northeastern Brazil, namely Estação Ecológica de Murici (ESEC Murici), RPPN Frei Caneca, and a forest preserve belonging

Revisiting ecological specialization: the case of plant–frugivore interactions
Oikos, Volume 2025, Issue 3, March 2025.Understanding the extent to which organisms exhibit specialization when interacting with or relying on distinct aspects of their biotic and abiotic environment is a central tenet in ecology and evolution. Despite the relevance of the concept and theoretical advances, specialization has and continues to be ambiguously defined. Here we review the uses of
