In order to compare the effectiveness of birds and insects as pollinators, we studied floral biology bromeliad Aechmea nudicaulis (L.) Grisebach in biome Atlantic rain forest, southern Brazil. On Santa Catarina Island, flowering extends from mid-September end December, with diurnal anthesis. The reproductive system is obligatory xenogamy, thus pollinator-dependent. Flowers secrete 31.84 μl nectar per day, a mean sugar concentration 23.2%. Highest volume occur at beginning Most traits are...
The goal of the present study was to identify plant species used as food source, floral resources utilized, and insects that visit flowers in a grassland community southern Brazil. carried out an area one hectare, located formation Parque Estadual de Itapuã, State Rio Grande do Sul, flowering pattern seasonal, richness abundance higher during period high resource availability. Flowers 106 angiosperms (73 genera 34 families) were source for 219 (2,767 specimens) insects. A total 91.5% visited...
On Santa Catarina Island bees were collected between 1999 and 2006 using various methods, including netting, trap nesting, baiting. Vegetation types sampled comprised secondary forests, dunes, pastures, parks. A checklist of 166 species is presented. The family Apidae was represented by the highest number species, followed Megachilidae Halictidae. Only a few Colletidae Andrenidae recorded. Species richness occurrence genera are compared to results other collections performed in neighboring...
Orchid bees (Apidae: Euglossini) are important pollinators of several angiosperms in the Neotropics, especially orchids (Dodson and Frymire, 1961; Dressler, 1968; Ramirez et al., 2002). bee males visit flowers that offer fragrances as resources to them pollinators. This association is known ‘‘Perfume Flower Pollination Syndrome’’ (Vogel, 1963; 1982). To collect fragrances, use their forelegs adsorb scents subsequently stored special structures located hindlegs (Dressler, Over course lives,...
Phenological studies assist in forest ecosystems comprehension and evaluation of resource availability for wildlife, as well improving the understanding relationships between plants their pollinators dispersers. This study aims to describe reproductive phenophases riparian plant species correlate them with climatic variables. The phenology was analyzed biweekly throughout one year, recording absence or presence flowers/fruits. flowering phenophase occurred an increase number blossom October,...
Decomposition of leaf litter from pioneer tree species and development associated soil meso- macrofauna are fundamental for rehabilitation processes in reclaimed coal mining areas. The aim our study was to evaluate decomposition Schinus terebinthifolius Senna multijuga answer three basic questions: (i) What type degrades faster min\ing areas? (ii) Is correlated with the stage regeneration exposure time? (iii) Does influence diversity abundance collected? Experiments were carried out state...
A comunidade de abelhas (Hymenoptera, Apoidea) foi estudada no Parque Estadual do Itapuã, município Viamão, que diz respeito à diversidade, abundância relativa e atividade sazonal. As foram coletadas sobre as flores em duas áreas florestais, durante dois dias consecutivos por área, quinzenalmente, das 8 h às 18 h. No total, capturadas 3.306 pertencentes a 95 espécies cinco famílias ocorrentes Brasil. Dentre elas, Apidae família mais abundante (2.860 indivíduos) diversificada (36 espécies),...
ABSTRACT Floral characteristics often indicate the pollinators' functional group visiting plant and pollination syndromes associated with them. This idea has been challenged in past decades due to increasing evidence that most plants, including those exhibiting floral syndromes, are visited by large arrays of species differ their effectiveness as pollinators. Our study focuses on Mecardonia tenella (Plantaginaceae) from Araucaria forest southern Brazil, which exhibits oil flower syndrome....
Flower visitors of the bromeliad Aechmea lindenii (E Morren) Baker exhibiting an ornithophilous floral syndrome were studied in a secondary Atlantic forest at Santa Catarina Island. During spring season flower visiting animals 21 species belonging to one bird and eight arthropod orders observed on 80 plants. The orchid bee Euglossa annectans Dressler 1982, stingless Plebeia droryana (Friese 1900) hummingbird Thalurania glaucopis Gmelin 1788 most frequent visitors. latter was found be...
ABSTRACT The production of fruits and seeds many crops is increased when bees visit their flowers pollinating them. aim this study was to evaluate the effect different pollination treatments on ‘Bordô’ grapevine (Vitis labrusca L.) fruit quantity quality. Quantitative qualitative parameters plants visited by Apis mellifera L., manually self- cross-pollinated without were analyzed compared. Fruit high for all presented four per fruit, average, confirming that grape cultivar autogamous....
Climate change is suggested to be one of the possible drivers decline in pollinators. In this paper, we applied an ecological niche model modeling distributional responses face climate changes for subspecies Melipona quadrifasciata Lepeletier. This species divided into two based on difference yellow tergal stripes, which are continuous M. q. and interrupted anthidioides. The geographic distribution each also distinct. found colder regions Southern states Brazil, whereas anthidioides habitats...
Data on mammals in Brazilian Restinga are scarce, especially chiropterans. This study aims to analyze the composition of bat assemblages a degraded environment southern Brazil. The samplings were carried out municipality Jaguaruna, coast Santa Catarina state, from 2006 2016. Bats captured mist nets at understory layer. Richness, abundance and frequency considered order describe assemblage structure. We 514 individuals two families, eight genera 14 species. Species accumulation curve did not...
As áreas protegidas privadas (PPAs) são fundamentais para preservar e conservar a biodiversidade, contribuindo na manutenção dos processos ecológicos. Por este motivo, atores privados estão cada vez mais gerenciando terras conservação, originando PPAs. Visto importância dessas áreas, estudo teve como objetivo apresentar evolução aspectos históricos, definições, classificações situação das no contexto internacional. Para isso, foram utilizados dados do Banco de Dados Mundial sobre Áreas...
Encounters between flowers and invertebrates are key events for the functioning of tropical forests. Assessing structure networks composed interactions those partners leads to a better understanding ecosystem effects environmental factors on ecological processes. Gathering such data is, however, costly time-consuming, especially in highly diverse tropics. We aimed provide comprehensive repository available flower-invertebrate interaction information Atlantic Forest, South American forest...
A qualidade dos recursos naturais no sul catarinense sofreu um impacto negativo com a atividade mineradora do carvão final século XIX. Projetos de recuperação ambiental estão sendo implantados há quase uma década, modificando o cenário da na região. O objetivo deste trabalho foi verificar se processo reabilitação das áreas degradadas resulta em melhora água, utilizando os insetos bentônicos como indicadores. As coletas fauna aquática foram realizadas sub-bacia rio Fiorita, Siderópolis, SC,...

This study aims to evaluate the litterfall production of three areas in tropical rain forest, different successional stages, municipality Siderópolis, Southern Santa Catarina state. Fifteen collectors 0.25 m2 each were used, distributed transects per area (A1, A2 and AR). The highest occurred AR (8,131 kg.ha-1), followed by (4,253 kg.ha-1) A1 (2,740 kg.ha-1). produced significantly more leaves, reproductive material wastes. can be explained its developed forest structure, with large trees,...
A dispersão de sementes por aves é um processo importante para a manutenção e conservação dos ecossistemas, pois aumenta as possibilidades recrutamento das espécies vegetais com diminuição da mortalidade densidade-dependente. Na Mata Atlântica, palmeiras estão entre principais famílias que disponibilizam grande quantidade frutos carnosos adaptados à zoocórica e, consequentemente, são favorecidas pelo pela fauna. Entre palmeiras, Euterpe edulis Mart. destaca-se como espécie-chave fauna,...
O descontrole na exploração de carvão nos municípios da região Sul Santa Catarina resultou em diversas áreas degradadas que necessitam intervenção humana processos recuperação. Entretanto, os modelos tradicionais recuperação dessas restringem-se a cobertura do solo e plantio espécies nativas. É extrema importância novos levem consideração interação animal-planta, especial polinização, devido sua relação com perpetuação das vegetais. Diante disso, o presente estudo visou analisar as...
