1. Histological survey of protocerebral areas and retrocerebral complex of Melipona quadrifasciata anthidioides workers (Hymenoptera, Apidae, Meliponini) / Mapeamento histológico das áreas protocerebrais e do complexo retrocerebral de operárias de Melipona quadrifasciata anthidioides (Hymenoptera, Apidae, Meliponini)
The stingless bees colony comprises a queen, workers of diferent ages that perform different tasks and males only present before the queen´s fecundation. Among the workers, only the oldest ones foragers keep a direct contact with the light/dark environmental cycle. Biological rhythms are present and are generated by the circadian system located in the centr

2. The lithics of Lagoa Santa: a study of hunters-gatherers technological organization from Central Brazil / Os líticos de Lagoa Santa: um estudo sobre organização tecnológica de caçadores-coletores do Brasil Central
As relações entre a variabilidade e a variação dos conjuntos líticos de dois abrigos-sob-rocha do carste de Lagoa Santa - MG são analisadas em relação às estratégias de sobrevivência empregadas pelos grupos caçadores-coletores locais para lidar com as mudanças na disponibilidade de recursos no decorrer do Holoceno Inicial e Médio. Os processos

3. Ontogenesis of respiratory rhythms in Melipona quadrifasciata adult workers (Hymenoptera, Apidae, Meliponini). / Variações ontogenéticas nos parâmetros do ritmo respiratório de operárias de Melipona quadrifasciata (Hymenoptera, Apidae, Meliponini).
The eusocial organization promotes a behavioural development of adult worker-bees, based on an age-related division of labour. Workers switch from tasks inside the hive to foraging and undergo a progressive transition from controlled environment of the hive to a diurnal exposure to the environment outside the hive. The coordination of queen and workers act

4. Influence of the workers bee behavioral status on the preoviposition period and survival of queens of Melipona quadrifasciata Lep. (HYMENOPTERA:MELIPONINI) in laboratory conditions. / Influência do status comportamental das operárias sobre o período de pré-oviposição e sobrevivência de rainhas de Melipona quadrifasciata Lep. (Hymenoptera: Meliponini) em condições de laboratório
In this work it was aimed at a) to investigate the influence of the workers bee behavioral status of different origins in the recognition process and defensive behavior; b) the influence of the age of the queens and of the workers bee behavioral status in the acceptance process of virgin queens; c) influence of the workers bee behavioral status on the surviv

5. Extended Parental Care in Communal Social Groups
Recent developments in social insect research have challenged the need for close kinship as a prerequisite for the evolution of stable group living. In a model communal bee species, Lasioglossum (Chilalictus) hemichalceum, previous allozyme work indicated that groups of cooperating adult females are not relatives. Yet at any given time, not all group members

6. Honeybee colony integration: worker-worker interactions mediate hormonally regulated plasticity in division of labor.
Adult workers in honeybee (Apis mellifera) colonies exhibit plasticity in hormonally regulated, age-based division of labor by altering their pattern of behavioral development in response to changes in colony conditions. One form of this plasticity is precocious development: levels of juvenile hormone increase prematurely and bees begin foraging as much as 2

7. Behavioral performance in adult honey bees is influenced by the temperature experienced during their pupal development
To investigate the possible consequences of brood-temperature regulation in honey bee colonies on the quality of behavioral performance of adults, we placed honey bee pupae in incubators and allowed them to develop at temperatures held constant at 32°C, 34.5°C, and 36°C. This temperature range occurs naturally within hives. On emergence, the young adu
