Filling the gaps on parasites of : Helminth community structure of (Anura: Hylidae) from the Brazilian Amazon.

is an arboreal anuran widely distributed in South America. However, there are no parasitological studies conducted on the species, resulting in a parasite fauna completely unknown. Thus, this study aims to characterize the parasitic community structure of in the municipality of Pedra Branca do Amapari, Amapá state, Amazon region, Brazil.

Two names, one species: redescription and phylogenetic position of Freitas, 1959 provides new insights into the evolutionary history of the Cosmocercidae.

are gastrointestinal parasites of anurans, distributed throughout Central and South America. and are some of the most commonly reported species parasitising anurans from Brazil, and the morphological differences between them are unclear. In the present study, we redescribed based on a re-examination of type series and newly collected material from the frog in the state of Amapá, Brazil.

A new species of Aplectana Railliet & Henry, 1916 (Nematoda: Cosmocercidae) in the Brazilian Amazon and the taxonomic status of Aplectana longa.

Nematodes of the genus Aplectana Railliet & Henry, 1916 are common parasites of the digestive tract of amphibians and reptiles in the Neotropical region. During a parasite survey on Boana boans (Linnaeus, 1758), we found specimens of nematodes with Aplectana characteristics. We observed a set of characteristics that differs the species of our study from its congeners, and the present study describes a new species of Aplectana parasite of B.

Rhabdias Stiles and Hassal, 1905 comprises approximately 90 species of parasitic lung nematodes of amphibians and reptiles that have a wide distribution, with 21 species occurring in the Neotropics. In the present study, we describe Rhabdias waiapi n. sp.

Ectoparasites infecting (Mugiliformes: Mugilidae) in Amapá state estuary, in the northern Brazilian coast region.

In fish, one of the most important interactions is that occur between parasite species and environment. Wild fish interactions with parasites of different taxa can result in diseases for fish and consequently damages to the fishing industry. This study investigated the ectoparasite fauna in (Valenciennes, 1836), in Amapá state estuary, in Brazilian coast region.

Description of the tadpole of Dendropsophus haraldschultzi (Bokermann, 1962) (Anura: Hylidae), with comments on reproductive biology.

The genus Dendropsophus Fitzinger contains 108 recognized species (Frost 2020) distributed in nine species groups according to Faivovich et al. (2005). However, recent phylogenetic analysis recognized the presence of nonmonophyletic groups (e.

The tadpole of Amazophrynella teko (Anura: Bufonidae) from the eastern Amazon, Brazil.

The genus Amazophrynella Fouquet, Recoder, Teixeira, Cassimiro, Amaro, Camacho, Damasceno, Carnaval, Moritz, and Rodrigues, is represented by 12 nominal species and distributed in the Amazon region of Brazil, Bolivia, Colombia, Ecuador, Guyana, French Guiana, Peru, and Venezuela (Frost 2020). In the last eight years, ten species from this genus have been described. However, despite the wide distribution and diversity of these species, only the tadpole of Amazophrynella manaos Rojas, Carvalho, Ávila, Farias, and Hrbek from the Brazilian Amazon (Menin et al.

New records of hosts for and (Crustacea: Isopoda) in brackish fish from the coast of the State of Amapá (Brazil), with an update on the geographic distribution of .

Fish are parasitized by several species of crustaceans, including Cymothoidae and Corallanidae. The aim of this study was to investigate the crustacean parasite fauna in , , , , , , , , , , , , , and from the coast of the State of Amapá, eastern Amazon. In addition, an update on the geographic distribution of in Brazilian Amazon is present.

The tadpole of Elachistocleis helianneae Caramaschi, 2010 (Anura: Microhylidae).

The neotropical genus Elachistocleis Parker comprises 18 described species [including Elachistocleis ovalis (Schneider) which is considered a nomen dubium by Caramaschi (2010), with pending revision]. This genus is distributed in Central America and most of South America, from Panama and Trinidad to southern Paraguay, including central Argentina, Uruguay, Venezuela, Colombia, Bolivia, Guyana, Surinam, French Guiana, and Brazil (Marinho et al. 2018; Frost 2019).

Richness and composition of anuran assemblages from an Amazonian savanna.

The Amazonian savannas occupy approximately 150,000 km of the Brazilian Amazon, occurring in scattered isolated patches over large areas of forest in the states of Amapá, Amazonas, Pará, Roraima and Rondônia. Despite having considerable variation in the Anuran composition between locations and between the savanna's physiognomies, a systematic and geographically wide sampling has not been performed for the savanna from Amapá yet, located in the north of Brazil, eastern Amazonia. In this perspective, a study was conducted on the richness, composition, diversity, and abundance of Anuran species in a ​​savanna area in Amapá State.

The advertisement call of the Hoogmoed's harlequin toad Atelopus hoogmoedi Lescure, 1974 from northern Brazil (Anura, Bufonidae).

Harlequin toads (Atelopus) are distributed over a wide range in the Amazon Rainforest, mostly associated with streamlets in dense ombrophilous forests in lowland and sub-montane regions. Atelopus hoogmoedi Lescure, 1974a was considered as bearing full species status by Lötters et al. (2005), although until that moment this species had been assigned to a subspecies of A.

Anuran species composition of Cancão Municipal Natural Park, Municipality of Serra do Navio, Amapá state, Brazil.

In this study, the first survey of anuran species in the Cancão Municipal Natural Park is presented, a protected area of approximately 370 hectares of Amazonian forest located in the northwest center region of the state of Amapá, Brazil. The work was performed during the dry and rainy season, through active visual and auditory survey, totaling 216 man hours of sampling effort. Forty-nine species of anuran amphibians were recorded in the Cancão Municipal Natural Park, including three new records: , Pristimantis cf.

Detection of Rickettsia spp. in ticks parasitizing toads (Rhinella marina) in the northern Brazilian Amazon.

This study evaluated rickettsial infection in ticks collected on toads from the northern Brazilian Amazon (Amapá state), where to our knowledge there are neither records of ticks from amphibians nor rickettsial infections in ticks. During 2016-2017, a total of 22 free-living toads were captured and identified as Rhinella marina. Overall, 12 (54.

Resource Partitioning between Two Piranhas ( and ) in an Amazonian Reservoir.

The exploitation of resources by closely related species with similar niches may be mediated by differences in activity patterns, which may vary in nycthemeral scale and seasonal scale. Piranhas and are Neotropical predators that occur sympatrically in many environments of the Amazon basin. To evaluate the strategies adopted by these two species in a restricted environment (a reservoir), nycthemeral and seasonal samples were made, identifying the composition of the diet and their activity patterns.

Restoration Effects of the Riparian Forest on the Intertidal Fish Fauna in an Urban Area of the Amazon River.

Urbanization causes environmental impacts that threaten the health of aquatic communities and alter their recovery patterns. In this study, we evaluated the diversity of intertidal fish in six areas affected by urbanization (areas with native vegetation, deforested areas, and areas in process of restoration of vegetation) along an urban waterfront in the Amazon River. 20 species were identified, representing 17 genera, 14 families, and 8 orders.

The advertisement call of Ameerega pulchripecta (Silverstone, 1976)(Anura, Dendrobatidae).

The name Ameerega picta was once used to denote a lineage of poison frogs (Dendrobatidae) distributed throughout most of the Amazon basin (Silverstone 1976); more recently, to describe a phenetic group involving at least 18 species, Lötters et al. (2007) pointed out that some of the lineages were indeed derived from the former A. picta.
