| We report an unusual reproductive behavior of Hypsiboas pardalis (Spix, 1824). Species belonging to this genus usually are known to reproduce in lentic water bodies, with the development of exotrophic tadpoles. Herein, the bromeligenous behavior is reported for the first time in Hypsiboas Wagler, 1830. Although this reproductive behavior has been observed more than once here, we believe that it is not typical of Hypsiboas, being better characterized as an unusual reproductive mode for Hypsiboas, indicating the presence of plasticity in the reproductive modes of H. pardalis |

| The collects from mosquitoes' sample that repro-duce in leaf imbricate of bromeliads were done by two differents methods: a conven-tional method where the plants were felled and the water inside were dropped in a recipient and in the second method the samples were collected by sucking the water, so the plant wasn't felled. The number of bromeliads studied in each method was 120 plants from zero to 15 m height. The period of study lasted from january till december 1989. The bromeliads were collected monthly by each method. The score of immature was done at the laboratory. The variables studied were the number of leaf axils with water (Xi, Yi), water volume (cm³) inside each bromeliad (X2, Y2), the number of immature mosquitoes (larvae and pupae) inside each... |

| Microorganisms that live inside and around a plant can supply it with essential substances, such as phytohormones and essential nutrients. The present investigation aimed to isolate and characterize the phyllosphere, the endophytic, and the water tank bacteria associated with Vriesea gigantea and Tillandsia aeranthos. The bacteria were tested for siderophore and indole-3-acetic acid (IAA) production, phosphate solubilization, and presence of the nif H gene. Genetic diversity of the bacterial isolates was evaluated by rep-PCR. Sixty-eight bacterial strains were isolated from 3 different microhabitats of V. gigantea and from 2 microhabitats of T. aeranthos bromeliad plants. Gram-positive, spore-forming bacilli comprised most bacterial isolates. All isolates... |

| Bromeliaceae is one of the most relevant taxonomic groups of the Atlantic Forest, where the Brazilian southeastern region stands out as a center of diversity and endemism for many taxa of the family. We present a checklist of the 12 genera and 44 species of Bromeliaceae from the Pedra dos Pontões, in Mimoso do Sul municipality, Espírito Santo state, southeastern Brazil. The Bromelioideae (22 species) was the subfamily with most taxonomic diversity, followed by Tillandsioideae (18 species) and Pitcairnioideae (four species). We also report the first occurrence of four species (A. squarrosa, N. antoineanum, V. pseudoatra and V. pardalina) for the Espírito Santo state. Almost half of the taxa surveyed inhabit exclusively the vegetation associated to the rocky... |

| ABSTRACT The phytotelm-dwelling frogs from the genus Phyllodytes Wagler, 1830 have been characterized as specialist frogs regarding their diet strategy which is mainly composed by colonial insects. Herein, we used two species of ants (Camponotus sp. and Gnamptogenys sp.) with distinct defensive mechanisms to test the predatory behavior of Phyllodytes luteolus Wied, 1824. The experiment was conducted with frogs inhabiting a patch of 20 bromeliads (Aechmea cf. blanchetiana). Ants were offered randomly to the frogs until we obtained ten observations of predation of each ant species. We observed and recorded the time that P. luteolus needed to keep each ant species inside its mouth before it could ingest it. Predatory behavior was highly distinct. While... |

| Bromeliaceae is a morphologically distinctive and ecologically diverse family originating in the New World. Three centers of diversity, 58 genera, and about 3,140 bromeliad species are currently recognized. We compiled all of the studies related to the reproductive biology, genetic diversity, and population structure of the Bromeliaceae, and discuss the evolution and conservation of this family. Bromeliads are preferentially pollinated by vertebrates and show marked variation in breeding systems, from predominant inbreeding to predominant outcrossing, as well as constancy in chromosome number (2n = 2x = 50). Autogamous or mixed mating system bromeliads have a high inbreeding coefficient (F IS), while outcrossing species show low F IS. The degree of... |

| Microsatellite markers previously developed for Pitcairnia albiflos Herb. and Pitcairnia geysksii L.B.Sm. were used in cross-amplification tests of five other Bromeliaceae species. Ten (76.9%) out of the 13 evaluated pair of primers had positive results for some of the species tested. The number of polymorphic alleles ranged between two and four in most species. Ho values ranged between zero, in Pitcairnia flammea Lindl. (PaA05), Aechmea ramosa Mart ex Schult & Schult and Billbergia horrida Regel (PaC05), and one in Billbergia euphemiae E. Morren (PaA05, PaA10, PaC05 and PaD07). This study showed that microsatellite markers developed for P. albiflos and P. geysksii effectively amplified the DNA samples of Pitcairnia flammea, Aechmea nudicaulis (L.)... |

| We performed a scientometry to validate trends in the scientific production on phytotelmata and the importance of these microenvironments in the maintenance of biodiversity. We searched for articles in the Web of Science and looked at publications from 1987 to 2016. We collected years of publication, surveyed organisms, countries where the surveys took place, plants that accumulate phytotelmata, scientific journals that publish more about the topic and their respective IFs (Impact Factor) and the keywords of each article. We built a heatmap using the most frequent keywords in the studies, to investigate the topics studied over the years. We have found 293 publications, increasing over the years. Insects, anurans and crustaceans were the most studied... |
