Seed production, pollination requirement, seed characteristics related to quality and the relationship between number and mass of seeds were examined for Panicum racemosum in three successional populations in southern Brazilian coastal dunes. The seed production was generally low and declined further between the frontal dunes and the backdunes, dropping from 4.05 seeds per panicle in the former to 1.8 seeds in the latter. However fertility (% fertile florets) did not differ among the three habitats. Plants cross-pollinated in a glasshouse showed an increase in seed production to 41.4 seeds compared to no seed production in self-pollinated plants. Caryopses varied in mass from 3.2 to 12.2 mg with a mean of 7.98 mg. A strong negative correlation was found...

A study of the reproductive biology of B. chinensis (L.) DC. (Iridaceae) was realized comprising floral biology and breeding systems. The floral biology studies included analyses of nectar production, occurence of osmophores, corolla pigments, ultraviolet reflexion and absortion patterns, viability of pollen, pollinators and flower visitors. The breeding systems were studied taking into account the results of manual pollinators tests. B. chinensis is self-compatible bul cross-pollination is more frequent. The effective pollinators are Plebeia droryana (Friese, 1906) (45,7%), Trigona spinipes (Fabricius, 1793) (27,3%), Tetragonisca angustula (Latreille, 1811) (9,3%). Others insects visitors are considered nectar and pollen thieves. The flowering begins...

For the first time the pollination of a poorly known, terrestrial orchid, Habenaria pleiophylla Hoehne & Schlechter, 1921 (Orchidaceae) by a passion vine butterfly, Heliconius erato phyllis (Fabricius, 1775) (Lepidoptera, Nymphalidae) is reported. Number of pollinia-carrying individuals was determined on a population of H. erato phyllis in Horto Florestal Barba Negra, Barra do Ribeiro County, Rio Grande do Sul State. The pollination mechanism was described under laboratory conditions, in association with the butterfly feeding habit and the orchid flower morphology. Habenaria pleiophylla pollinia are cemented during nectar feeding on the ventral portion of the compound eyes near H. erato phyllis proboscis base. The pollinia are transferred to the...

(Biologia floral de Vochysia cinnamomea Pohl (Vochysiaceae) em cerrados do Triângulo Mineiro, MG). Vochysia cinnamomea é uma arvoreta de cerrado comum na região do triângulo mineiro. Apresenta flores zigomorfas com pétalas amarelas e cálice gamossépalo com um dos lobos maior e calcarado. As flores abrem pela manhã e duram apenas um dia. Apresentam um estame que se desprende durante a antese, depositando o pólen no estilete, o que representa um tipo de apresentação secundária de pólen. As flores são visitadas principalmente por abelhas do gênero Epicharis e outras Anthophoridae, que são os polinizadores primários, mas beija-flores e esfingídeos diurnos também foram observados. A planta é parcialmente autocompatível, sendo os frutos formados por...

This work aimed to study the pollination ecology of the tropical weed Triumfetta semitriloba Jacq. (Tiliaceae), in Viçosa, South-eastern Brazil, during the flowering season of 1993 and 1994. Two patches located in pasture (P1 and P2) and one patch in a forest trail (P3) were chosen and ten plants on each patch were sorted. The number of opened flowers were counted during one day, in each flowering month and patch. All observed flower visitors were identified and their behavior while visiting flowers was recorded. Frequency of visits to flowered branches was obtained and some pollinator individuals were captured for analysis of pollen load. Flowers are conspicuously yellow and actinomorphic, with five nectaries around the ovary base, and opened sequentially...

A biologia floral e a polinização por abelhas Euglossini de uma Annonaceae é descrita pela primeira vez e as adaptações a esse modo de polinização são comparadas às de outras espécies da família, que é predominantemente polinizada por coleópteros. A espécie Unonopsis guatterioides foi estudada em dois fragmentos de mata de terra firme no município de Manaus (AM). As flores são protogínicas e permanecem abertas expondo os estigmas e estames durante a antese que ocorre entre dois dias. São visitadas por machos de Eulaema bombiformis (Euglossini) que coletam o odor o qual se assemelha ao de "capim cidreira" (Andropogum nardus L.). Visitas de abelhas Meliponidae e coleópteros Chrysomelidae também foram registradas. Unonopsis guatterioides apresenta dicogamia...

Inspite of Etythrina species exhibit morphologic attributes for adaptation to pollination by nectarivorous birds mentioned in the literature, E. speciosa is pollinated by lots of bees (Apinae and Meliponinae) which show a great urban occurrence. Systems of E. speciosa floral reproduction, fenology, diversity, frequency and constancy of insects visiting at different hours and flowering periods were studied. E. speciosa is Biocompatible, but xenogamy is the predominant system of reproduction. A large diversity of insects visiting the inflorescences was observed, with predominance of bees. The bee species showed a higher frequency: Apis mellifera Linnaeus, 1758 (45,0 %), Trigona spinipes (Fabricius, 1793) (28,6%), Trigona hyalinata (Lepeletier, 1836) (12,2 %)...

Ecosystem health and agricultural wealth in North America depend on a particular invertebrate fauna to deliver pollination services. Extensive losses in pollinator guilds and communities can disrupt ecosystem integrity, a circumstance that today forces most farmers to rely on honey bees for much fruit and seed production. Are North America's invertebrate pollinator faunas already widely diminished or currently threatened by human activities? How would we know, what are the spatiotemporal scales for detection, and which anthropogenic factors are responsible? Answers to these questions were considered by participants in a workshop sponsored by the National Center for Ecological Analysis and Synthesis in October of 1999, and these questions form the nucleus...

North American Dipteran Pollinators: Assessing Their Value and Conservation Status

Ecology and Society

Kearns, Carol Ann; University of Colorado at Boulder; kearnsca@rtt.colorado.edu.

Recent attention to pollinator declines has focused largely on bees and vertebrates. However, few pollination systems are obligate, and pollinators that complement the role of bees may respond differently to environmental disturbance. The conservation status of North American fly pollinators remains undocumented. In this paper, methods for monitoring shifts in dipteran pollinator abundance are discussed. The need for further basic research into pollination by flies is addressed, and the significance of dipteran conservation is considered.

Habitat Fragmentation and Native Bees: a Premature Verdict?

Ecology and Society

Cane, James H; USDA-ARS; jcane@biology.usu.edu.

Few studies directly address the consequences of habitat fragmentation for communities of pollinating insects, particularly for the key pollinator group, bees (Hymenoptera: Apiformes). Bees typically live in habitats where nesting substrates and bloom are patchily distributed and spatially dissociated. Bee studies have all defined habitat fragments as remnant patches of floral hosts or forests, overlooking the nesting needs of bees. Several authors conclude that habitat fragmentation is broadly deleterious, but their own data show that some native species proliferate in sampled fragments. Other studies report greater densities and comparable diversities of native bees at flowers in some fragment size classes relative to undisrupted habitats, but find...

A field survey of flowering plants used as food resource by the adults of Heliconius erato phyllis (Fabricius, 1775) was carried out in four sites located in Rio Grande do Sul state, Brazil. Samples were taken in preserved areas of the Atlantic Rain and Myrtaceae forests, an Eucalyptus plantation, and an urban park. Adult feeding frequencies on flowers were registered monthly from December 1996 to May 1997, on plants located on previously marked 200 m long transects. Flowers on which H. erato phyllis fed in the field were collected, drawn and morphometrically characterized. Feeding was registered on flowers of twenty-three species, of which seventeen are new records for H. erato in Brazil . The use of a given plant varied among localities, as a function of...
