Orchidaceae, one of the most numerous families in the world's flora, have evolved various
pollination strategies to favour cross-pollination, such as deceptive pollination and …

Small carpenter bees (genus Ceratina) are excellent taxa for studying early stages of social
evolution, as they have high within and between species variability in social and parental …

Solitary bees play a crucial role in ecological systems, contributing to the pollination of crops
and wild plants. All females are reproductive, and their habitat requirements include nesting …

It is increasingly recognised that intraspecific variation in traits, such as morphology,
behaviour, or diet is both ubiquitous and ecologically important. While many species of …

Arrhenotoky is the typical mode of reproduction in Hymenoptera. Diploid females develop
from fertilized eggs, whereas haploid males originate from unfertilized eggs. However, some …

Galls induced by Lipara lucens on common reed are adopted by bees and wasps as a
nesting cavity. Most of these species occur only in wetlands. Some of them are specialised …

We provide herein the first report of a nest of Ceratina (Ceratinula) fioreseana Oliveira, 2020,
a species that was recently described for the Cerrado domain. The nest was collected in a …

Arrhenotoky is typical mode of reproduction for Hymenoptera–females originate from
fertilized eggs, males from unfertilized eggs. However, some lineages of Hymenoptera have …

This thesis is made under the project “Seeds & Bees: selection of autochthon plants seeds
for the restoration and improvement of habitat for pollinators and biodiversity, made by …
