We present the taxonomic treatment of Evolvulus in the state of Ceará, as part of the project "Flora do Ceará: Knowing to conserve". The study was based on the floristic-morphological analysis of specimens deposited in the ASE, CEN, EAC, ESA, HCDAL, HST, HUEFS, HUVA, HVASF, IPA, PEUFR, and UFP herbaria, specialized bibliography, typus collections available on on-line platforms, collections and field observations. In Ceará, we registered 13 species of Evolvulus: E. anagalloides, E. cardiophyllus, E. eleaegnifolius, E. ericifolius, E. filipes, E. glomeratus, E. gypsophiloides, E. linoides, E. nummularius, E. ovatus, E. phyllanthoides, E. pterocaulon, and E. sericeus. Of these, ten occur in protected areas from Ceara state. The greatest species richness for the genus (10) was registered in the open crystalline caatinga. Additionally, we present an identification key, morphological descriptions, geographic distribution, taxonomic and ecological comments, phenology and illustrations of the diagnostic characters of the species.

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).

We present the taxonomic treatment of Convolvulaceae for the Meruoca Massif, located in the Northwest region of the Ceará state, where there are remnants of Tropical Pluvial Sub-deciduous Forest (Dry Forest) and Tropical Pluvial-Nebular Rainforest (Wet Forest). The present study was based on the morphological analysis of specimens collected in the field and from the collections EAC, HUEFS, HUVA, PEUFR, and SPF. We recorded 24 species distributed in four genera: Ipomoea (18 species), Jacquemontia (three species), Distimake (two species), and Camonea (one species). We report the first records of I. cearensis for Atlantic Forest and I. aristolochiifolia to the state of Ceará. The taxonomic treatment includes identification key, morphological descriptions, geographic distribution, taxonomic and ecological comments, the period of flowering and fruiting, and photos and illustrations of the diagnostic characters.

The article focuses on a study which compared tidepool fish assemblages within and among habitats at Iparana and Pecém beaches, State of Ceará, Northeast Brazil using visual census techniques. The researchers conducted underwater censuses in four tidepools located along intertidal reefs at the beaches of Iparana. Study findings suggested that the taxonomic composition of fish species in Iparana and Pecém was consistent with several studies on tidepool fish fauna in the Brazilian coast. It concluded that tidepool ichtyofauna may be variable between and within reef sites.
