Abstract This study aimed to provide the floristic survey of Onagraceae in Ceará state. The floristic study consisted of analyzing material deposited in the herbaria EAC, ESA, FUEL, HCDAL, HUEFS, HUVA, HVASF, INPA, K, MO, NY, P, RB, UFRN and US, as well as field work carried out between 2015 and 2017. In the study area, Onagraceae is represented by the genus Ludwigia, and seven species were recorded: L. erecta, L. helminthorrhiza, L. hyssopifolia, L. leptocarpa, L. nervosa, L. octovalvis and L. tomentosa. All seven species were also sampled in Conservation Units, with L. erecta recorded in six of them. L. erecta and L. helminthorrhiza have a broader distribution in the state. L. nervosa and L. tomentosa are indicated as new occurrences for Ceará, both with only one record in the south of the state, expanding their range in Northeastern Brazil. The information in this manuscript allows identification of Onagraceae representatives in Ceará state, through morphological descriptions, identification keys, taxonomic comments, illustrations, photographs and geographic distribution data.

We present a list of aquatic and wetland plant species from the state of Paraíba, Brazil, based on the collections deposited in national and international herbaria. We identified 290 species belonging to 61 families. The checklist includes habit, localities of the collections in the state of Paraíba, and geographic distribution of each species. The amphibious habit was the most prevalent and the Sertão (semiarid inland region) was the region with the greatest collection effort. New occurrences have been registered for the state (14 species). Although our data reveal a high plant richness, we relate this richness to increased field expeditions.

ABSTRACT Seeking to expand the floristic studies for the Atlantic rainforest, we herein present, based on field trips (January 2011 to April 2013) and herbarium records, a list of vascular plants found in the Mata do Junco Wildlife Refuge, State of Sergipe, Northeastern Brazil. We registered a total of 380 species, 244 genera and 80 families, with 45 new occurrences for the Atlantic rainforest of the State of Sergipe. The most representative families were Fabaceae (36 species), Cyperaceae (29) and Poaceae (28). Herbs were the most representative regarding habit (167 species or 44%). We found two threatened species: Caesalpinia echinata Lam. and Campylocentrum pernambucense Hoehne, both in the "endangered" category. Overall, the results indicate that the Mata do Junco Wildlife Refuge is floristically similar to other areas of Atlantic rainforest in the State of Sergipe. Moreover, the existence of new records and of a threatened native species reinforces its importance for conservation.

Abstract The Cerrado is one of the most threatened biomes in Brazil. It is estimated that much of its original vegetation has been replaced by some type of human use. This is quite worrying, mainly in the northern part where the number of wildlife inventories is insufficient and creates the false impression of low diversity in the region. The Parque Estadual do Mirador-PEM, located in the south-central region of the state of Maranhão, presents vegetation typical of the Cerrado biome and corresponds to one of 46 priority areas for conservation in the state. Herein, we describe the species richness and composition of the anurofauna from the PEM and analyze the influence of different types of vegetation in its formation. Our inventory was conducted from December 2013 to February 2015, using the active search and auditory census methods on breeding sites in different water bodies of the park. We recorded 31 anuran species belonging to five families (species number in parentheses): Leptodactylidae (14), Hylidae (12), Bufonidae (3), Microhylidae (1) and Phyllomedusidae (1). The rarefaction curve and species richness estimators indicated that the sampling effort was enough to record most of the species in the region. The richness of anurans in the PEM was higher than reported by other authors for several areas of Cerrado. Most species have a wide distribution in Brazil or are strongly associated with the Caatinga or Amazon biomes. Only about 19% are endemic to the Cerrado biome. This study is the first to inventory the anurans species of the south-central region of state of Maranhão and provides important data on amphibian communities from the northern part of the Brazilian Cerrado.

The genus Xenohyla is currently composed of two species, X. truncata (Izecksohn, 1959) and Xenohyla eugenioi Caramaschi, 1998. Both species are usually found inside bromeliads; X. truncata inhabits the restingas of the state of Rio de Janeiro, southeastern Brazil, and X. eugenioi transitional areas between the Atlantic Forest and the Caatinga biomes in northeastern Brazil. We report the first record of X. eugenioi in the state of Sergipe, expanding the species geographic distribution by 423.4 km in a straight line in relation to its type locality, in the municipality of Maracás, south-central state of Bahia, Brazil.

"Restingas" (herbaceous/shrubby coastal sand-dune habitats) used to cover most of Rio de Janeiro State coast, and have suffered extensive degradation over the last five centuries. Using satellite images and field work, we identified the remaining restingas in the State, recording the factors that might cause their degradation. We used two mosaics of Landsat 7 scenes (spatial resolution 15 and 30 m) to map and evaluate preliminarly the remaining areas and conservation status. Each remnant area was checked in the field, degraded areas within it were mapped and subtracted from the remnants. We identified 21 restinga remnants totalling 105,285 ha. The largest and smallest restinga remnants were Jurubatiba (25,141 ha) and Itaipu (23 ha), respectively. We identified 14 causes of degradation. The most important were vegetation removal for housing developments, establishment of exotic plant species, change of original substrate, and selective removal of species of economic importance for the horticultural industry. All restingas had disturbed parts under strong pressure due to human activities. Due to intense habitat loss, and occurrence of endemic/threatened vertebrate species in restinga habitats, we strongly indicate the implementation of new conservation units to protect these fragile remnants. This habitat is steadily decreasing and most remnants lack legal protection. Therefore, under the current human pressure most of this unique habitat is likely to be lost from the State within the next few years.

The known diversity of treefrogs of the genus Phyllodytes has rapidly increased in recent years, currently comprising 14 species. Recent field work in the Atlantic Rainforest of the state of Bahia lead to the discovery of a new large species of Phyllodytes which is herein described based on multiple evidence including morphological, acoustical and genetic data. Phyllodytes sp. nov. is one of the largest species within the genus and presents immaculate yellowish dorsum and limbs. The advertisement call of the species is composed of 7–31 notes (half pulsed/pulsatile-half harmonic) with frequency-modulated harmonics. Phyllodytes sp. nov. has a karyotype of 2n = 22 chromosomes, as also found in other species of the genus. Genetic distance values of the 16S mitochondrial rRNA among Phyllodytes sp. nov. and its congeners range between 6.4 to 10.2%. The description of another new species for this state reinforces the need for further taxonomic work with Phyllodytes in this region that has been revealed as a priority area for research and conservation of this genus.
