Fruit set of distylous Psychotria carthagenensis Jacq. (Rubiaceae) mediated by Apis mellifera (Apidae) and species of Augochloropsis (Halictidae) Acta Botanica
Faria,Rogério Rodrigues; Araujo,Andréa Cardoso.
Heterostyly is a floral polymorphism consisting in the presence of two morphs in the population that differ reciprocally in the position of their sexual organs. Heterostylous species depend on visitors to produce fruits, but the efficiency of insect species as pollinators greatly varies and depends on the morph visited. The aim of the present study was to determine the effect of a single visit by the bees Apis mellifera and species of Augochloropsis on the fruit set of the distylous species Psychotria carthagenensis.After a single visit from each bee species, flowers were bagged to monitor the fruit set. Pollination effectiveness between pollinators and morphs was compared. The results of the experiments were compared with data from manual intermorph...

Pollination biology and reproduction of Seemannia sylvatica (Kunth) Hanstein (Gesneriaceae) in the Serra da Bodoquena National Park, Mato Grosso do Sul Biota Neotropica
Camargo,Eduardo; Rodrigues,Licléia da Cruz; Araujo,Andréa Cardoso.
In Brazil, the family Gesneriaceae is represented by 23 genera and approximately 200 species. Seemannia sylvatica is an herb that occurs in dense populations in the riverbeds at Serra da Bodoquena. Goals of this study were to report the floral biology (on the first five days of anthesis), as well as to determine the breeding system and the pollinators of S. sylvatica. Data collection was conducted from June 2005 to July 2006 through monthly field trips, lasting for five days. Data on floral biology, breeding system and on the floral visitors were taken from individuals located along a track 2500 m long, in riparian forest of Salobrinha river. Flowers of S. sylvatica are tubular, red, with no perceptive odor and lasted more than five days (ca. 10 - 20 days...

Checklist of the flora in ironstone outcrops at the Urucum Plateau, Corumbá, Mato Grosso do Sul Biota Neotropica
Lima,Michele Soares de; Takahasi,Adriana; Damasceno-Junior,Geraldo Alves; Araujo,Andréa Cardoso.
Abstract: "Cangas" are ironstone outcrops occurring at the foot of the Urucum Plateau, on the western edge of Pantanal, Corumbá-MS. In Brazil, the knowledge about flora and ecology of the plant communities associated with these formations is still incipient. These habitats are among the most threatened and less studied in Brazil because of their association with high quality iron ore deposits. We present a cheklist of the flora from these formations, resulting from different authors' collecting efforts in 10 areas of the Plateau. A total of 302 species have been recorded; they were distributed in 53 botanical families and 175 genera. Poaceae (43 species), Fabaceae (41), Euphorbiaceae (22), Cyperaceae (19), Malvaceae (19), Convolvulaceae (15), Malpighiaceae...

Bees (Hymenoptera: Apoidea) and flowers in natural forest patches of southern Pantanal Biota Neotropica
Boff,Samuel; Araujo,Andréa Cardoso; Pott,Arnildo.
This is the first systematic survey of bees in the Pantanal wetland, Brazil. We recorded bee species and their floral resources within grassland and natural forest edge habitats in the Pantanal. Surveys were conducted during two to four-days per month, for a total of 12 months. Overall, we recorded 56 bee species visiting a total of 63 flowering plants. Asteraceae and Fabaceae presented the highest number of visited species, however Hyptis suaveolens (Lamiaceae) was the plant most visited by different bee species (18). The most generalist native bee was Trigona fuscipennis visiting a total of 17 flowering plant species. Apis mellifera, an exotic bee, visited 27 species. We also report the overlap (37.5%) in the use of floral resources between the exotic...
