Eldorado, 09972-270, Diadema, SP, Brazil Abstract: Direct facilitation is characterized by the positive effect of one individual on the other through changes in abiotic conditions and the creation of novel habitats. We aimed to present a systematic review of the literature about direct facilitation in tropical forests, emphasizing knowledge gaps and suggesting future lines of inquiry. We asked: (1) What is the existing literature about direct facilitation in tropical forests? (2) What kind of methodological approach (experimental or observational) has been more used? (3) What kind of study, pairwise species or community level, are more common? (4) What vegetative habits are more common between facilitators and facilitated species? (5) What hypotheses are more commonly tested? (6) How often epiphytism has been approached as facilitation? Based on literature search, we found thirty-five studies examining direct facilitation in plants mainly in the Neotropics (69%). The number of observational and experimental studies was similar. Most studies were based on pairwise comparisons of species. Trees were the most common nurse plants representing 51% of the studies, followed by shrubs (20%). This was the same for facilitated plants: trees corresponded to 48% and shrubs to 21%. The most common facilitation mechanism in tropical forest was the improvement of aboveground microclimate conditions (43%). Epiphytism is still marginally explored (11%, only 4 out of 35 studies) as a direct mechanism of facilitation. Given that about nine per cent of the world vascular flora are epiphytes that demand facilitators to survive, it is timely to widen the scope of field studies about facilitation towards such direct mechanisms.

Flowers visited by hummingbirds in an urban Cerrado fragment, Mato Grosso do Sul, Brazil. Biota Neotrop. 13(4): http://www.biotaneotropica.org.br/v13n4/en/ abstract?article+bn00213042013 Abstract: Hummingbirds are the main vertebrate pollinators in the Neotropics, but little is known about the interactions between hummingbirds and flowers in areas of Cerrado. This paper aims to describe the interactions between flowering plants (ornithophilous and non-ornithophilous species) and hummingbirds in an urban Cerrado remnant. For this purpose, we investigated which plant species are visited by hummingbirds, which hummingbird species occur in the area, their visiting frequency and behavior, their role as legitimate or illegitimate visitors, as well as the number of agonistic interactions among these visitors. Sampling was conducted throughout 18 months along a track located in an urban fragment of Cerrado vegetation in Campo Grande, Mato Grosso do Sul, Brasil. We found 15 species of plants visited by seven species of hummingbirds. The main habit for ornithophilous species was herbaceous, with the predominance of Bromeliaceae; among non-ornithophilous most species were trees from the families Vochysiaceae and Malvaceae.

Although invasive species can have substantial impacts on animal communities, cases of invasive species facilitating native species by removing their predators have rarely been demonstrated across vertebrate trophic linkages. The predictable spread of the invasive cane toad (Rhinella marina), however, offered a unique opportunity to quantify cascading effects. In northern Australia, three species of predatory monitor lizards suffered severe population declines due to toad-induced lethal toxic ingestion (yellow-spotted monitor [Varanus panoptes], Mertens’ water monitor [V. mertensi], Mitchell’s water monitor [V. mitchelli]). We, thus, predicted subsequent increases in the abundance and recruitment of prey species due to the reduction of those predators. Toad-induced population-level declines in the water monitor species approached 50% over a five-year period spanning the toad invasion, apparently causing fledging success of the Crimson Finch (Neochmia phaeton) to increase from 55% to 81%.

    REVIEW ARTICLE DOI: 10.1038/s41467-018-06779-w OPEN Ecology and evolution of facilitation among symbionts Flore Zélé 1, Sara Magalhães 1, Sonia Kéfi 2 & Alison B. Duncan 2 Facilitation occurs when one species positively impacts the fitness of another, and has predominantly been studied in free-living species like plants. Facilitation can also occur among symbiont (mutualistic or parasitic) species or strains, but equivalent studies are 1234567890():,; scarce. To advance an integrated view of the effect of facilitation on symbiont ecology and evolution, we review empirical evidence and their underlying mechanisms, explore the factors favouring its emergence, and discuss its consequences for virulence and transmission. We argue that the facilitation concept can improve understanding of the evolutionary forces shaping symbiont communities and their effects on hosts. 1 cE3c: Centre for Ecology, Evolution, and Environmental Changes, Faculty of Sciences, University of Lisbon, Edifício C2, piso-3, 1749-016 Lisboa, Portugal. 2 ISEM, Université de Montpellier, CNRS, EPHE, IRD, Montpellier Cedex 05, France.

Abstract: Different frog-bromeliad associations are frequently reported from various habitats of Central and South America. Here, we present the first data on the association of two hylid species (Dendropsophus nanus and Scinax nasicus) with the bromeliad Bromelia balansae in the Brazilian Pantanal. Both treefrog species use rosettes of B. balansae as a diurnal shelter and foraging ground.
