“…The pollen types identified in the State of Sergipe were found in other studies throughout Brazil, such as in the states of Bahia (Novais et al 2010), Minas Gerais (Modro et al 2011) and Piau ı (Lorenzon et al 2003), and even in other countries such as Mexico (Villanueva-G. 2002). Amongst the 46 pollen types identified in the bee pollen loads from Sergipe, 29 have an affinity with apicultural plant species indicated by Santos et al (2006) for the semiarid vegetation from northeast Brazil.…”

“…Also, comparisons with the data of several atlases were used for pollen type identification (Moncada & Salas 1983;Barth 1989;Roubik & Moreno 1991;Mart ınez-Hernand ez et al 1993;Silva 2007;Lima et al 2008;. The characteristics regarding the habit (arboreal, shrubby, herbaceous, liana and climber) of the plants related to each pollen type were obtained from Marchant et al (2002), Brito et al (2006), Queiroz (2009) and Modro et al (2011).…”

In Brazil, the production of bee pollen loads began modestly in the late 1980s, stimulated by consumption of natural products. Demand and consumption have increased, and there has been no increase in scientific studies. This work aims to expand scientific knowledge by identifying the plants used by Apis mellifera L. as sources of pollen loads in the State of Sergipe, Brazil. Twelve samples were collected from January to December 2011, in the municipalities of Barra dos Coqueiros, Brejo Grande, Estância and Pacatuba, all located in the eastern region of Sergipe. For the study of the pollen grains, the bee pollen underwent the usual laboratory processing techniques (acetolysis). For the analysis 500 grains were counted from each sample and, for botanical identification, the specialised literature and the pollen library were used. A total of 46 pollen types, distributed in 19 families, were found. Fabaceae was the family displaying the greatest diversity of pollen types (19), and the genus Mimosa L. was the most diverse (8). The families Asteraceae, Anacardiaceae, Myrtaceae and Rubiaceae were represented by three pollen types each, and Lamiaceae, only two types. The other 13 families presented one pollen type each. Only eight pollen types were classified as very frequent (> 50%); however, only Cocos nucifera occurred in 100% of the samples. It can be concluded that the families Arecaceae and Fabaceae are the major pollen sources for production of bee pollen in the state of Sergipe, followed by Asteraceae, Anacardiaceae, Poaceae and Rubiaceae. Pollen spectra revealed that at least 29 genera of plants contribute to the bee pollen load production in the tropical rainforest zone in northeastern Brazil.

“…In native vegetation of the Caatinga in the state of Paraiba, 14 pollen types collected by Melipona subnita were identified (MaiaSilva et al, 2015), whereas 52 pollen types for the same bee in the Lençóis Maranhenses National Park-Brazil (Pinto et al, 2014). The intrinsic learning of each colony, genetic characteristics, flower characteristics, availability of trophic resources and different levels of competition, are factors that influence the bees' collection behavior (Modro et al, 2011;Oliveira et al, 2009).…”

The objective of this study was to identify the species of pollen supplying plants that constitute the trophic niche of Melipona mandacaia in an urban area in the Caatinga domain (a tropical arid landscape). The collection of pollen in the colonies was carried out every 15 days, from October 2014 to September 2015. The pollen was removed directly from the storage pots in three distinct colonies. A total of 24 samples were analyzed and compared with the reference pollen collection, pollen catalogs and specialized literature. For the quantitative analysis, at least 1000 pollen grains per sample were identified. A total of 39 pollen types were identified, distributed in 17 botanical families, being one an indeterminate type. The most represented family was the Fabaceae (n = 16). The most frequent types were Leucaena leucocephala, Mimosa pudica and Melochia sp. There was a significant positive correlation between temperature and the number of pollen types throughout the study. Relative humidity and rainfall were abiotic variables that did not present a significant correlation. The rarefaction curve showed that probably most of the pollen types collected by the bees studied were sampled, since the accumulation curve showed a progressive tendency to stabilization, indicating that there was sample adequacy of the pollen types. The analysis of similarity revealed a high sharing of pollen sources between colonies.

“…Despite the negative aspects mentioned, mistletoes can also play an important role in urban ecosystems as they provide a food source for several animals (Cazetta and Galetti 2003;Modro et al 2011;Maruyama et al 2012), in addition to providing physical support for the construction of nests by several bird species (Cooney et al 2006). As suppression of the mistletoes in urban landscapes may compromise the fauna that depends on them, management of persisting urban mistletoe populations may be a better option (Watson 2001), and, consequently, information on the prevalence and intensity of mistletoe infection of urban trees is highly useful in urban forestry, as it facilitates more efficient management and monitoring of these plants.…”

One of the problems affecting the quality of urban trees is their infestation by mistletoes (aerial hemiparasite plants of the order Santalales). Identification of the main types of trees infested, and of the causes of infestation patterns, can help infestation control and the planning of efficient planting regimes. In this sense, the aim of this study was to evaluate the patterns of hemiparasite infestation in trees in an Amazonian urban environment. We aimed to answer (1) which species of mistletoes occur on urban trees in the city of Santarém, in the Brazilian Amazon; (2) what is the proportion and intensity of infestation on infected trees; and (3) if differences in infestation rates among tree species can be explained by mistletoe-tree compatibility. We assessed mistletoe incidence and intensity of infestation on trees in the main avenues of the city. To evaluate the role of mistletoe-tree compatibility in the observed parasitism patterns, we carried out a seed inoculation experiment with seeds of the most abundant mistletoe, Passovia theloneura. Seeds were planted on three tree species (Andira inermis, Handroanthus serratifolius, and Mangifera indica). The overall infestation rate was 19.3%, with exotic tree species more infested than natives. The experiment showed that incompatibility between P. theloneura and the native H. serratifolius is primarily responsible for the observed non-infestation. Mistletoes germinated on A. inermis grew better than those on M. indica, contrary to the infestation prevalence found in the field, suggesting that patterns of infestation are also influenced by seed deposition processes.

Identificação das principais espécies de árvores infestadas e das causas da infestação pode ajudar a controlar as ervas-de-passarinho e orientar o plantio de novas espécies de árvores. Nesse sentido, o objetivo deste estudo foi avaliar o padrão de infestação de hemiparasitas em árvores em um ambiente urbano da Amazônia. Nós buscamos responder: (1) quais espécies de ervas-de-passarinho ocorrem nas árvores urbanas da cidade de Santarém, na Amazônia Brasileira, (2) qual é a proporção e intensidade de infestação nas árvores afetadas e (3) se diferenças nas taxas de infestação entre as espécies de árvores podem ser explicadas pela compatibilidade entre ervas-de-passarinho e hospedeiro. Nós amostramos árvores nas principais avenidas da cidade. Para avaliar o papel da compatibilidade entre a erva-de-passarinho e o hospedeiro nos padrões de parasitismo observados, conduzimos um experimento de inoculação de sementes com a erva-de-passarinho mais abundante, Passovia theloneura. Sementes foram plantadas em três espécies de hospedeiros (Andira inermis, Hand...
