“…Saff., are found at the study site, where the most species-rich tree families are Fabaceae, Myrtaceae and Lauraceae. The following are most abundant tree species at the study site (Correia et al, unpublished Kuijt (2003), the species is distributed throughout the Lesser Antilles, Central America and South America, except Chile, Argentina and Uruguay, at elevations ranging from sea level to 2000 m. The species is a monoecious, aerial hemiparasitic shrub, characterized by opposite, coriaceous and glabrous leaves, and bears spike inflorescences, forming globose and single-seeded berries (3 mm in diameter) that are yellowish-orange when ripe (Kuijt 2003;Moreira & Rizzini 1997). The species is easily recognizable by the pronounced parallel nervures on its leaves (Moreira & Rizzini 1997), and its fleshy fruits are locally consumed by birds such as Euphonia chlorotica (Linnaeus, 1766) (A.V.…”

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 of Atlantic Forest in southeast Brazil. We surveyed 397 tree individuals of 50 species within 25 families. Seven of those species (14%) bore P. crassifolium infections. Although prevalence at the individual level was low (11.6%), there were marked deviations in infection levels among species and families. Most (87%) of the infections (40 of 46) occurred in species belonging to the families Anacardiaceae (Lithraea molleoides and Tapirira guianensis) and Siparunaceae (Siparuna guianensis), which nevertheless accounted for only 26% of the potential individual hosts (103 of 397). We also performed an experiment simulating bird behavior. We inoculated 480 mistletoe seeds to the bark of four potential hosts in field, following the fate of the seeds for five months. No differences in host preference were observed. The low specificity detected at the local level was confirmed by a survey of exsiccata collected over the geographical distribution of the mistletoe, suggesting that P. crassifolium prevalence is more dependent on dispersal limitation than on mistletoe-host compatibility.

available online at httpj//www.idealibrary.com on I BE bl 0 @ Four sites with contrasting environmental stress in southeastern Brazil: relations of species, life form diversity, and geographic distribution to ecophysiological parameters Some ecophysiological parameters related to plant performance and fitness (carbon and nitrogen isotope composition and total C and N concentrations; in situ chlorophyll fluorescence measurements) were determined for over 30 species in four habitats bordering the montane Atlantic rain forest of Brazil, along a gradient of altitude and rainfall: a dry coastal forest, two areas of sandy coastal plain vegetation (restingas), and a high altitude campo. There was a considerable diversity of ecophysiological behaviour within and between the functional groups we created based on plant life-forms. For instance, both crassulacean acid metabolism (CAM) and C3 species were found in most life-forms sampled and throughout all habitats. Despite the variation in rainfall regimes, average overall water-use efficiency was similar between sites, particularly for C., species, while no clear pattern regarding nitrogen-use emerged in this respect. Acute and chronic photoinhibition were found in many species across this gradient, even in CAM plants. However, on average, chronic photoinhibition and lower energy dissipation capacity were more characteristic of plants from the restinga habitats. This suggests that, although plants colonizing these habitats have evolved features to deal with water shortage, adaptation to high light levels has not been fully achieved yet. The ecophysiological performance of some individual species in distinct habitats and in distinct microhabitats within habitats is also discussed. !

“…The author recognized 112 Neotropical species, including 34 currently placed in Santalaceae (formerly included in subfamily "Viscae"). Since then, publications mainly focused on regional accounts or studies on specific genera (e.g., Sugiyama & Mantovani 1987;Sugiyama 1992;Rizzini 1995;Moreira & Rizzini 1997;Caetano et al 2002;Stannard 2004;Reif & Andreata 2011;Dettke & Waechter 2014;Caires 2018;Araújo et al 2020). In Northeastern Brazil, the only states that present floristic treatments are Paraíba (Vasconcelos & Melo 2015) and Sergipe (Oliveira & Caires 2018).…”

Flora of Ceará, Brazil: Loranthaceae

This study provides a taxonomic treatment for the species of Loranthaceae in the state of Ceará, Northeastern Brazil. The survey was made based on the previous consultation of virtual herbaria, in loco visits, material loans, and photographs of diagnostic traits sent by herbarium curators. Morphological traits and geographic coordinates of all specimens collected in the State were recorded to prepare the distribution maps, identification key, and taxonomic descriptions for each taxon. A total of 184 specimens (discounting duplicates) from 30 herbaria were studied. Eight species are recorded for Ceará: Passovia pedunculata, Passovia pyrifolia, Psittacanthus cordatus, Psittacanthus dichroos, Psittacanthus eucalyptifolius, Struthanthus marginatus, Struthanthus polyrrhizus, and Struthanthus syringifolius. None are included in the IUCN Red List. However, four of them were collected inside protected areas (i.e., Passovia pedunculata, Psittacanthus cordatus, S. polyrrhizus, and S. syringifolius).
