1. COMUNIDADE DE INSETOS ASSOCIADOS AOS SICÔNIOS DE TRÊS ESPÉCIES DE FIGUEIRAS NO PANTANAL SUL MATOGROSSENSE / INSECT COMMUNITY ASSOCIATED WITH SYCONIA OF THREE FIG SPECIES IN PANTANAL SUL MATOGROSSENSE
Sicônios de figueiras apresentam uma diversificada interação com diferentes grupos de organismos. Neste estudo, nós caracterizamos a comunidade de insetos associados a três espécies de figueiras na região do Miranda/Abobral, Pantanal Sul matogrossense, obtendo dados sobre a riqueza de espécies e a abundância destes insetos. Verificamos a especificid

2. Caracterização ultraestrutural dos espermatozóides de três espécies do gênero Idarnes
Idarnes is a nonpollinating fig wasp genus associated with Ficus, section Americana. These wasps are known as mutualisms parasites because they exploit the mutualism established between the fig and their pollinator, causing a negative effect on pollinator wasp production, therefore affecting the figs ability to disperse pollen. We studied three species of Id

3. Efeito de vespas galhadoras (Hymenoptera: Chalcidoidea) na duração da receptividade floral de Ficus citrifolia (Moraceae) / Galler wasps (Hymenoptera, Chalcidoidea) effect on th length of floral receptivity of Ficus citrifolia (Moraceae)
The breeding success of Ficus trees and the maintenance of their mutualistic fig wasps depend on the successful pollination of pistilate flowers (seed production) and on the development of pollinating wasps in some galled ovaries (production of pollen vectors). The period during which pistilate flowers are receptive for pollination and oviposition is short c

4. Strategies of resource utilization in parasitic fig wasps / Estratégias de utilização de recursos em vespas parasitas do mutualismo figueiras - vespas de figo
Interações ecológicas interespecíficas que resultam em benefício para todos os organismos participantes são conhecidas como mutualismo. No entanto, a troca de benefícios apresenta custos para as espécies participantes. Este fato abre espaço para o surgimento de espécies que adotam estratégias oportunistas, denominadas parasitas de mutualismos. As

5. Pollination and parasitism in functionally dioecious figs.
Fig wasps (Agaonidae: Hymenoptera) are seed predators and their interactions with Ficus species (Moraceae) range from mutualism to parasitism. Recently considerable attention has been paid to conflicts of interest between the mutualists and how they are resolved in monoecious fig species. However, despite the fact that different conflicts can arise, little i

6. Cryptic species of fig-pollinating wasps: Implications for the evolution of the fig–wasp mutualism, sex allocation, and precision of adaptation
Fig-pollinating wasps have provided model systems for developing and testing theories of the evolution of mutualism, sex allocation, and precision of adaptation. With few exceptions, previous studies have assumed one species of pollinator wasp per host fig species. Here we report genetic data demonstrating the coexistence of previously undetected cryptic fig

7. Phylogenetic relationships, historical biogeography and character evolution of fig-pollinating wasps.
Nucleotide sequences from the cytochrome oxidase I (COI) gene were used to reconstruct phylogenetic relationships among 15 genera of fig-pollinating wasps. We present evidence supporting broad-level co-cladogenesis with respect to most but not all of the corresponding groups of figs. Using fossil evidence for calibrating a molecular clock for these data, we

8. Pollination mode in fig wasps: the predictive power of correlated traits.
The over 700 species of Ficus are thought to have co-speciated with their obligate pollinators (family Agaonidae). Some of these wasp species pollinate figs actively, while others are passive pollinators. Based on direct observations of mode of pollination in 88 species, we show that mode of pollination can confidently be predicted from fig traits only (anth

9. Modes and origins of mechanical and ethological isolation in angiosperms.
Mechanical and ethological isolation between species is widespread in angiosperms with specialized animal-pollinated flowers, being recorded in 29 species groups belonging to 27 genera and 16 families. Mechanical isolation occurs in two forms. (i) The common type, designated the Salvia type, operates when two or more species of flowers are adapted for differ
