Phytosociology a Humid Forest of the Chapada of Araripe, Crato, CE, Brazil

The Chapada of Araripe is an exceptional landscape in the Caatinga, a seasonally dry tropical forest of northeastern Brazil, as it shelters several vegetation types, such as Carrasco, Cerrado, Cerradão and Humid Forest, different from the biome in which it is inserted. The first three phytophysiognomies mentioned above are already relatively well documented. However, studies of the Humid Forest of the Chapada of Araripe are still incipient. In this context, the objective of this work was to contribute to the knowledge of the composition and structural organization of the flora of a wetland area of the Chapada of Araripe, Crato-CE. The research was developed from April 2014 to February 2016 and all individuals with CAP ≥ 15 cm were sampled. The botanical material was collected in 100 plots (100 m × 10 m), between coordinates 7º14′36″S, 7º15′23.5″S and 39º28′50″W, 39º29′30.8″W at an elevation between 904 m and 963 m, at the top of the Chapada of Araripe, Crato-CE. The testimonial material was deposited in the Herbarium Caririense Dárdano de Andrade-Lima of the Regional University of Cariri. We sampled 3,067 individuals distributed in 59 species. The total basal area was 43,278 m2 and the density was 3,067 per hectare. The families Fabaceae, Myrtaceae, Rubiaceae, Lauraceae and Chrysobalanceae presented greater specific richness. The species Ocotea nitida (Meisn.) Rower, Protium heptaphyllum (Aubl.) Marchand, Licania sp. and Cordiera myrciiflora (K. Schum.) C. H. Press. & Delprete were the most important to the community due to the high IVI for the sampled area. The first occurrence of the genus Helicostylis for Ceará was recorded. The Humid Forest of Chapada of Araripe presents floristic elements from the Amazon Region, Cerrado and species of Atlantic Forest Domain.

Pycnandra is a genus of Sapotaceae (Chrysophylloideae), restricted to New Caledonia, and includes ~60 species. The genus is a member of the monophyletic Niemeyera complex of Australia and New Caledonia and it is characterised by the lack of staminodes and a fruit containing a single seed, plano-convex cotyledons and absence of endosperm. In New Caledonia, several segregate genera have been recognised, but weak cladistic support for these groups and homoplasious morphology renders a narrow generic concept untenable. Instead, a broad generic circumscription of Pycnandra with an infrageneric classification recognising the subgenera Achradotypus, Leptostylis, Pycnandra, Sebertia and Trouettia results in a stable nomenclature. Here we revise Pycnandra subg. Achradotypus that includes 14 species, of which five (P. belepensis, P. blaffartii, P. bracteolata, P. glabella, and P. ouaiemensis) are described as new. Members of subg. Achradotypus are distinguished from other subgenera on the basis of a character combination of two stamens opposite each corolla lobe (except P. litseiflora), glabrous leaves (except P. belepensis and P. decandra), a distinctive reticulate tertiary leaf venation (except P. comptonii), and sepal-like bracts that often are borne along the pedicel. All species are restricted to Grande Terre except for P. decandra, whose distribution also extends to nearby Art Island (Belep Islands), and P. belepensis, which is endemic to that same island. The members grow in a wide range of vegetation types from dry maquis to humid forest, from sea level to the highest mountain massif, and on ultramafic soils to schist and greywacke (not limestone). Because of past and present threats such as mining, logging and fire, preliminary IUCN Red List assessments are provided for all species. Five taxa (P. chartacea, P. decandra subsp. decandra, P. glabella, P. litseiflora, and P. neocaledonica) are proposed the IUCN status Endangered, and P. belepensis and P. ouaiemensis are proposed to be Critically Endangered. We suggest that some locations where these species occur should be given protection in the form of nature reserves.

SummaryClimatic and ecological factors can influence the parasite load of a host. Variation in rainfall, body size, and sex of the hosts may be related to the abundance of parasites. This study investigated the helminth fauna associated with a population of Norops brasiliensis, together with the effect of host biology (sex, body size, and mass) and variation in rainfall regime on the abundance of helminths. Species of three groups of endoparasites were found (Nematoda, Cestoda, and Trematoda), with nematodes as the most representative taxa with eight species, prevalence of 63.2 %, mean intensity of 4.0 ± 0.58 (1 – 25), and mean abundance of 2.66 ± 0.44 (0 – 25). Nine helminth species are new host records for N. brasiliensis. The nematode Rhabdias sp. had the highest prevalence (53.3 %). There was no significant relationship between abundance of the trematode Mesocoelium monas and host sex or season, although the abundance of this parasite increased significantly with host body size and mass, while abundance of nematodes was related to season and host mass. This study increases the knowledge about the diversity of helminth fauna associated with N. brasiliensis, revealing infection levels of hosts from northeastern Brazil.

In this study, we report the temporal occurrence and habitat and microhabitat use by anurans in two areas located in one highland marsh (brejo-de-altitude) in northeastern Brazil. Fieldwork was carried out between September 2011 and September 2012. The recorded anurans belong to 14 species distributed in five families: Hylidae (six), Leptodactylidae (five), Bufonidae, Odontophrynidae and Pipidae (one each). Vocalization activity was seasonal and concentrated in the wetter and warmer months, but correlated to rainfall only in the top in the Chapada do Araripe. Richness and abundance of calling anurans were lower in the humid forest of the slope than in Cerradão area in the top of the Chapada do Araripe. Scinax x-signatus vocalized during nine months, and along with Dendropsophus soaresi, Phyllomedusa nordestina and Physalaemus cuvieri presented the longest periods of vocalization with the highest number of species vocalizing in at the height of the rainy season. Males were recorded vocalizing in nine different microhabitats, Adenomera sp. uses leaf litter and P. cuvieri the edge of water bodies as calling site both two sampled areas. Differences in richness and abundance of anurans between the two habitats are probably due to physical characteristics, such as presence of lentic environments.

Raillietiella gigliolii is a Neotropical pentastomid parasite found in Amphisbaena alba. Collections were made in northeastern Brazil in a remnant area of Atlantic Forest (07º 10' S and 35º 05' W) in the municipality of Cruz do Espírito Santo, Paraíba State, and in a Humid Forest area (07º 16' S and 39º 26' W) on the slopes of the Chapada do Araripe Mountains, municipality of Crato, Ceará state, Brazil. Nine specimens of A. alba and 12 of A. vermicularis were collected to gather basic ecological data (prevalence and mean intensity of infection) concerning these parasites. Raillietiella gigliolii was found infecting the lungs of both species. The prevalence for A. alba was 55.5% (5/9), with a mean intensity of infection of 5.0 ± 2.53 and amplitudes of 1-13. A. vermicularis demonstrated prevalence of 50%, with a mean intensity of infection of 5.3 ± 2.1 and amplitudes of 1-14. This represents the first record of R. gigliolii as a parasite of A. vermicularis. Our results suggest that R. gigliolii is a generalist parasite species and that an overlapping diet is the determinant factor in the sharing of its final hosts.

Vriesea baturitensis is described and illustrated as a new species. It is compared with V. friburgensis and V. rodigasiana, which we consider to be morphologically the most related species. The new taxon occurs in isolated Atlantic forest patches along the Baturité mountain range, in central-north Ceará state, Northeastern Brazil. It is characterized by the compact and regular rosette, a rounded leaf apex, stiff and erect peduncle, peduncle and primary bracts bright yellow, and the particular colors and sizes of the floral bracts and sepals. The humid habitat where the new species was found, known in Brazil as brejo de altitude, is surrounded by the Caatinga (Brazilian dry woodland) and due to its climatic conditions supports a rich flora of epiphytes. In Pico Alto we collected and photographed six different species of bromeliads, two of each being Guzmania and Vriesea, one of each being Aechmea and Racinaea. We conclude that the area of Pico Alto is an important remnant of humid forest and conservation measures to protect its epiphytes are urgently needed.

A New Species

Bauhinia includes about 150 species distributed across the tropics. Most Neotropical species belong to Bauhinia ser. Cansenia that includes unarmed trees and shrubs, mostly from areas under seasonally dry climate. A new species of this series is described here from the northeastern Brazilian states of Bahia and Sergipe. Bauhinia corifolia occurs in open vegetation on sandy soils of Restinga vegetation at the Atlantic coastal forests. It is morphologically similar to B. acuruana by sharing the entire and ovate leaflet with a retuse to emarginate apex and a cordate base, but differing by its tall shrub to treelet habit, larger leaves with a glabrous and glossy upper surface, shorter bracts, and longer flowers. We provide description, illustration and distribution map for the new species.

Study Aim. To assess species diversity and tree regeneration patterns of different vegetation types of Western Ghats, India. Rarefaction was used to estimate species diversity of different vegetation types. One-way ANOVA was used to test for differences in tree density and basal area of different vegetation types. Sorenson index of similarity was used to calculate change in species composition between mature trees and regenerating individuals. Results showed that species diversity and regeneration pattern of trees differ in different vegetation types of the forest landscape. Species-area and species-individual accumulation curve (rarefaction) against equal-sized sampling area in different vegetation types showed that species heterogeneity was higher in vegetation types at mid elevations while their abundance was higher in vegetation types at higher elevations. All the vegetation types of the study area were heterogeneously distributed. Tree regeneration was higher in species rich vegetation type with no sign of human disturbances. Change in species composition across mature and regenerating phase was more frequent in disturbed forest as compared to undisturbed or less disturbed forests. New entry species occur in all the vegetation types.

Spondias mombin L. is a fruit tree from the American continent from the Anacardiaceae family. In Brazil it is common in different vegetation types but is more frequent in the Atlantic and Amazonian rainforests. It is economically important because of its fruits, which are widely consumed raw or processed as fruit jellies, juices and ice creams. The leaves have great importance in the pharmaceutical industry because of their antibacterial properties. In the state of Pernambuco, cajá tree is widely distributed in the Zona da Mata region and less frequently in the Agreste and Sertão areas. In this work diversity and genetic structure were studied in four populations of cajá tree from Pernambuco's Zona da Mata, Northeast Brazil, using isozymes polymorphism analyses from electrophoreses. The result showed 100% of polymorphism (P) for nine alleles <img src="/img/revistas/rbf/v31n1/a24car02.jpg" align="absmiddle"> and the average of alleles per locus s was 2.4. The expected heterozygosity <img src="/img/revistas/rbf/v31n1/a24car01.jpg" align="absmiddle">ranged from 0.530 to 0.574 and the observed heterozygosity <img src="/img/revistas/rbf/v31n1/a24car03.jpg" align="absmiddle">, from 0.572 to 0.735. It was not observed inbreeding and the average F IT was -0.175, whereas within population inbreeding (f) varied from -0.08 to- 0.37. The genetic divergence among the populations (F ST) ranged from 0.006 to 0.028 and the average was 0.026. The average of estimated gene flow (Nm) was high (5.27). The CG-IPA population, corresponding to the germplasm collection of IPA, showed more than 96% of genetic similarity with other populations; therefore, it is a good representative of the existent genetic diversity in the Zona da Mata region.
