Abstract The African catfish (Clarias gariepinus) is considered one of the most important species of catfish for aquaculture. It has a great capacity to withstand several stress factors, such as harsh abiotic conditions, in addition to wide feeding flexibility. However, the species was detected in the Guapimirim Environmental Protection Area in southeastern Brazil, threatening native fish diversity and ecosystem functioning of this ecosystem. In 2018, during the dry and wet seasons, samples of the fish community were collected at thirty-two sites of the Guapi-Macacu River, in addition to abiotic variables (salinity, pH, temperature, turbidity, dissolved oxygen, and transparency) to diagnose which factors influence the distribution of the alien species along the river. Multivariate analyses indicated that African catfish dominate the region in the buffer zone to the Environmental protection area, benefiting from higher levels of dissolved oxygen and temperature. However, C. gariepinus does not dominate yet the most protected area of Guapimirim, where the highest percentage of native fish species inhabit. Climate change associated with changes in abiotic factors might significantly contribute to the dominance of the invasive alien species in this protected area, which might colonize the entire river.

This study aimed to identify taxa belonging to the genera Monoraphidium and Ankistrodesmus (Chlorophyceae, Chlorophyta) in two wetland areas of Pantanal dos Marimbus (Baiano and Remanso) in the Marimbus-Iraquara Environmental Protection Area, Bahia State, Brazil, and contribute to the knowledge of Chlorophyceae of Bahia State and Brazil. The materials studied, which were of periphytic and metaphytic origin, came from 64 samples collected in April and June 2011. We identified 18 taxa, 13 from Monoraphidium and five from Ankistrodesmus. Eight taxa were additions to the continental microalgae flora of Northeastern Brazil. Two taxa rarely found in Brazil were collected during the study: Monoraphidium dybowskii and M. litorale.

Abstract Mundaú river basin is located at Center-North Ceará State and occupies a total area of 2,227 km2, including Estuário do Rio Mundaú Environmental Protection Area. This study aimed to catalog the fishes of this basin. Collections were performed with active and passive gear in 35 sampling sites, between 2012 and 2014, in several habitats (main channels, streams, floodplains, permanent and temporary pools, ponds, and dams). A total of 2,545 specimens were collected, belonging to 55 species distributed in 10 orders, 31 families, and 50 genera; 30 of these are strictly freshwater species, and 25 estuarine-marine species. Three species (Hemigrammus guyanensis Gery, 1995, H. rodwayi Durbin, 1909 and Poecilia sarrafae Bragança & Costa, 2011) represent new records for the Mid-Northeastern Caatinga ecoregion. Besides, two cynolebiid species, Hypsolebias sp. and Anablepsoides cearensis (Costa & Vono, 2009), were found and the latter, currently classified as critically endangered, had its occurrence area widened.

Eggs And Larvae

SummaryIn the current study, the structural characteristics of the egg and larva of the pentastomid Raillietiella mottae (Almeida, Freire, & Lopes 2008), are described and compared with those of other pentastomids. The eggs and larvae were obtained from lizards Phyllopezus periosus (Rodrigues 1986) and Phyllopezus pollicaris (Spix 1825) which were collected in the environmental protection area of Cachoeira de Missão Velha, Ceará state, northeastern Brazil (7° 13’ S; 39° 08’ W). Following collection, the specimens were transported to the Laboratorio de Zoologia (LZ-URCA) and deposited in terrariums to obtain the feces, which were collected and analyzed for the presence of pentastomid eggs. The eggs found were typical of the genus Raillietiella, differing from those of other genera due to the lack of an outer fl exible membrane. The larva had two pairs of limbs, each with a pair of terminal hooks. The limbs were unsegmented, ventrally curved, and supported by conical muscle structures with visible segmentation. The tail was bifurcate, and each section had a terminal bristle. Information on egg and larval morphology can be useful in the identification of genera and species. The current study provides a description of the eggs and embryos of a Pentastomida species from the Neotropical Region.

ABSTRACT Dimorphandra mollis is native to the Brazilian Savanna and has social, economic and environmental importance. This study aimed to evaluate the yield and diametric distribution of Dimorphandra mollis Benth. in the Pandeiros River Environmental Protection Area, in Bonito de Minas, Minas Gerais state, Brazil. Five areas were assessed, totaling five hectares (50 plots of 1,000 m2). The total number of plants, yield per plant (2018, 2019 and 2020) and diameter at breast height were recorded, considering all trees from the plots in diametric classes. The average diameter at breast height of all plants was 6.05 ± 3.07 cm, and that of the plants that produced in at least one of the evaluated years was 7.46 ± 3.15 cm. The diametric distribution showed classes with no individuals, indicating imbalance, as well as a trend to inverted “J” shape. The maximum annual yield was 8.08 kg ha-1 of dry fruits (2019), the minimum 0.42 kg ha-1 (2018), and the average 2.74 kg ha-1, with biennial characteristic.

Few Data

Abstract Amphibian research has grown steadily in recent years in the Amazon region, especially in the Brazilian states of Amazonas, Pará, Rondônia, and Amapá, and neighboring areas of the Guiana Shield. Even so, few data are available for the Amazonian savannas of Brazil. To contribute to the understanding of the diversity of the amphibians of these savannas, we surveyed 15 temporary ponds, six located in open areas, seven on the edge of savanna forest, and two within the forest, in the savanna of the Rio Curiaú Environmental Protection Area (EPA) in Macapá, in the state of Amapá, northern Brazil. Sampling occurred from May 2013 to August 2014 during periods when the ponds contained water. Amphibians were sampled through visual and auditory surveys conducted during both the day- and the nighttime periods on seven days each month over a total of 84 days. A total of 1574 individuals belonging to four families, 12 genera, and 28 species were recorded during the surveys. The cumulative species curve reached the asymptote, indicating that sampling effort was adequate. The number of species was 25% higher than that reported in other studies in Amazonian savannas. Twelve species were recorded for the first time in the savanna of Amapá. Lysapsus boliviana was the most common species (n = 332 of the individuals recorded). The greatest amphibian species richness found in the Rio Curiaú EPA was associated with the savanna mosaic, forest patches, lowland swamp, and temporary ponds. The results of this study contribute to the understanding of the diversity of amphibian species in the Guianan area of endemism in northern Brazil, and also the Amazonian savannas.
