1. Structural development of the fruits and seeds in three mistletoe species of Phoradendron (Visceae: Santalaceae)
Resumo Phoradendron é um gênero de plantas hemiparasitas clorofiladas do Novo Mundo, que tem distribuição desde os Estados Unidos até a Argentina, incluindo o leste da Índia. Os nomes dados aos frutos de representantes de Visceae são variáveis, incluindo baga viscosa ou pseudobaga, apresentando uma única semente sem testa. Nesse trabalho, foi realiz

2. Host preference of the hemiparasite Struthanthus flexicaulis (Loranthaceae) in ironstone outcrop plant communities, southeast Brazil
Struthanthus flexicaulis is a hemiparasite abundant in ironstone outcrops in southeast Brazil. We evaluated its host preference among species of the plant community, taking into account the abundance and foliage cover of the hosts. The importance of each species in the community and the mortality caused by the parasite were assessed based on a quantitative s

3. Hemiparasitism effect on Baccharis dracunculifolia DC. and consequences to its major galling herbivore
ABSTRACTMistletoes obtain nutrients and water from their hosts, with varying effects among those hosts. We assessed the factors that influence the colonization of the mistletoe Struthanthus flexicaulis on Baccharis dracunculifolia and the subsequent effects on host performance. We evaluated the incidence of S. flexicaulis according to size (height classes) a

4. Host specificity and experimental assessment of the early establishment of the mistletoe Phoradendron crassifolium (Pohl ex DC.) Eichler (Santalaceae) in a fragment of Atlantic Forest in southeast Brazil
Mistletoe establishment relies heavily on a seed reaching a proper host plant. Small frugivorous birds usually disperse large numbers of mistletoe seeds. However, in the field, mistletoes are absent from some potential available hosts. We investigated whether the mistletoe Phoradendron crassifolium has some preferences for specific host trees in a fragment o

5. Two mistletoes are too many?: Interspecific occurrence of mistletoes on the same host tree
Mistletoe can have a major impact on the fitness of the host plant. If there is more than one species of mistletoe on the same host tree, the overall impact might be amplified. We report the occurrence of more than one species of mistletoe on the same host tree. Although it is not a rule in the field, to our knowledge, there have been no studies of this topi

6. A infestação da vegetação arbórea do Passeio Público de Curitiba, Paraná, por erva-de-passarinho: um estudo de caso.
Foi analisada a infestação por erva-de-passarinho na população arbórea do Passeio Público de Curitiba,PR. No local predomina a vegetação arbórea nativa, correspondendo a 68% da composição florística total de 130 espécies de árvores nativas e exóticas. Essa predominância se repete, também, em relação ao número de indivíduos encontrados (6

7. História natural da erva-de-passarinho Psittacanthus robustus (Loranthaceae) em uma área de campo rupestre do sudeste brasileiro : interações com hospedeiras, dispersores, polinizadores e insetos herbívoros / Natural history of the mistletoe Psittacanthus robustus (Loranthaceae) at a rupestrian filed site in southeastern Brazil : interactions with hosts, seed dispersers, pollinators and insect herbivores
In this study I investigated some aspects of the natural history of the woody mistletoe Psittacanthus robustus Mart. (Loranthaceae) in rocky outcrops in the Serra do Cipó, southeastern Brazil. This species was recorded parasitizing eight host species in Five families, although trees within Vochysiaceae comprise the main hosts. Pattern of distribution was cl

8. Especificidade de hospedeiros por Struthanthus aff. polyanthus (Loranthaceae) em uma área de cerrado, Uberlândia, Minas Gerais
O objetivo deste estudo foi verificar se Struthanthus aff. polyanthus apresenta especificidade por hospedeiros em área de cerrado do Clube Caça e Pesca Itororó de Uberlândia, e discutir se a abundância dos hospedeiros e arquitetura dos galhos influenciam a relação de especificidade. A área amostrada de 1,3 ha foi percorrida registrando-se a ocorrênc

9. Apparent response of small cell lung cancer to an extract of mistletoe and homoeopathic treatment.
A patient with small cell lung carcinoma was treated initially with extracts of mistletoe and homoeopathic treatment and appeared to respond. Subsequently radiotherapy was given and the patient lived for five years seven months, which is much longer than is usual with this type of tumour.
