In the present study, we provide new tick records from Vilhena Municipality, in the Southeast of the State of Rondônia, Northern Brazil. Ticks collected from a capybara, Hydrochoerus hydrochaeris (Linnaeus), were identified as Amblyomma romitii Tonelli-Rondelli (1 female), and Amblyomma sp. (1 larva). Ticks collected from a harpy eagle, Harpia harpyja (Linnaeus), were identified as Amblyomma cajennense (Fabricius) (16 nymphs) and Haemaphysalis juxtakochi Cooley (1 nymph). Ticks collected from a yellow-footed tortoise, Chelonoidis denticulada (Linnaeus), were identified as Amblyomma rotundatum Koch (10 females, 2 nymphs), and Amblyomma sp. (2 larvae). The present record of A. romitii is the first in the State of Rondônia, and represents the southernmost record for this tick species, indicating that its distribution area is much larger than currently recognized. Although both A. cajennense and H. juxtakochi have been reported parasitizing various bird species, we provide the first tick records on a harpy eagle. A. rotundatum is widespread in the State of Rondônia, and has been previously reported on the yellow-footed tortoise. The present records increase the tick fauna of Rondônia to 26 species.

Lithodytes lineatus (Schneider, 1799) is a medium-sized frog distributed throughout South America and found in Brazil in the Amazonia and Cerrado domains. Here we document two new records of the species in forested areas in the state of Amapá, Northern Brazil, and provide an updated distribution map for it. The record of L. lineatus in the state of Amapá extends its distribution approximately 78 km from the nearest locality, Floresta Estadual do Paru, in the municipality of Monte Alegre, state of Pará, Brazil, and help to fill information gaps.

Birdwatching is a growing segment of ecotourism and South America’s protected areas have an enormous potential to contribute to the development of this activity. We present a simple protocol to assess the potential of protected areas to attract and receive birdwatchers. The protocol is based on the application of raw scores using the following criteria: i) potential of local avifauna to attract birdwatchers, ii) logistic facilities of the protected area, and iii) services for accommodation, communication, health support and transport available in the municipality/ies located near the protected area. The protocol was applied in a protected area located in the State of Acre, in the southwestern part of the Brazilian Amazon. Thirty bird species (11% of avifauna) achieved the highest level of attractiveness for birdwatchers. The protected area and its neighboring municipalities show median capacity for hosting birdwatchers. The application of the protocol in other protected areas will be necessary to improve its applicability. The method, however, could be useful for a preliminary analysis of the birdwatching potential of protected areas.

We present a preliminary list of the avifauna found at the Estação Ecológica do Cuniã (ESEC Cuniã) in Porto Velho, northern Rondônia, Brazil. This inventory is based on systematic records obtained by mist-netting and camera trapping and non-systematic visual and audio records collected within the study area in 2017 and 2019. The combined dataset includes 135 bird species representing 37 families. Among these species are endemic birds and migratory birds. Four of the species are described in the last decade, and the records represent expansions of these species’ known ranges to the state of Rondônia. Overall, the data show that the ESEC Cuniã has a considerable diversity of bird species and is important for the conservation of the fauna of the floodplains of the Amazon basin.

The common green racer Philodryas viridissima (Linnaeus, 1758) is an arboreal and terrestrial snake species broadly distributed in southern Venezuela, Colombia, Ecuador, Peru, Bolivia, Guiana, Suriname, French Guiana, Paraguay up to Argentina, and most of Brazil. In this study, we report the first record of P. viridissima in the state of Acre, Brazil, in the Chico Mendes Extractive Reserve. This record expands the species distribution in 280 km to the southwest of Boca do Acre, state of Amazonas, which was the nearest record of this species in Brazilian Amazon until now.

We report the first record of this species from the state of Acre (Brazil) in the Serra do Divisor National Park. This record extends the species distribution in 540 km to the southwest of Tabatinga, state of Amazonas, which was the nearest record of this species in Brazilian Amazon.

Gynandromorphism is a condition in which an organism simultaneously exhibits male and female morphological characteristics. In Colombia, the taxon Amblyomma cajennense is represented by the species Amblyomma patinoi and Amblyomma mixtum. In September of 2014, in the Colombian Orinoco region, adult ticks were collected and determined from natural infections in bovines and equines. A gynandromorph was described from a natural infestation on a bovine, and morphologically classified as A. mixtum. This is the first literature report of a gynandromorph of A. mixtum, and the first description of a gynandromorph for a tick species in Colombia.

Abstract Introduction: Hyperphosphatemia is associated with unfavorable outcomes, and the percentage of patients presenting with this condition in hemodialysis (HD) in kidney foundation units in the state of Santa Catarina (SC) is historically higher than that of patients in the state of Tocantins (TO). Objective: To assess the frequency of consumption of the main dietary sources of phosphorus and to compare them between the two states. Methodology: A cross-sectional study was carried out involving 123 patients, 66 of SC and 57 of TO: 52% were men, average age was 46.9 ± 15.7 years, and mean HD time 48 (57-71) months. A food frequency questionnaire (FFQ) with 33 items that are dietary sources of phosphorus was applied. A consumption score was calculated for sources of organic, inorganic, and total phosphorus, and the six-month average of phosphatemia was obtained. Results: The mean phosphatemia of SC patients was higher (6.2 ± 1.5 vs 4.7 ± 1.3 mg/dL, p <0001) than TO patients, as well as the prevalence of hyperphosphatemia (62% vs 28%; p <10001). In the total sample, the foods most frequently consumed were milk and beans. Comparing the frequency of consumption between the two states, a significant difference was found in 17 items. In TO, beef and beans were the foods most frequently consumed, and in SC, fourteen other items of the FFQ (pork, sausages, dairy products, etc.) were the most frequently consumed. Phosphatemia correlated with the frequency of consumption of inorganic phosphorus sources. Conclusion: the frequency of consumption of several items was different between the states, and this explains the differences in phosphatemia between the two regions.

ABSTRACT Peperomia is the second most diverse genus of Piperaceae, with an estimated 1,600 species and a pantropical distribution. This work aims to present a taxonomic synopsis of the genus in the State of Roraima, in the extreme north of the Brazilian Amazon forest and belonging to the central-south portion of the Guayana Shield. Based on collecting expeditions and analysis of specimens in various herbaria, 23 taxa were recognized, with two new records for the State and one of them, a new record for Brazil. The taxa are differentiated mainly by phyllotaxis, shape and size of their leaves, in addition to habit and fruits. They have been found in areas of lowland, submontane, montane, tepui and floodplain (várzea) forests and mostly show a distribution restricted to the Neotropics. Some species in the state are presently known exclusively from Mount Roraima, and restricted to a few specimens.

The State

Paxillus is a neotropical genus belonging to the subfamily Passalinae widespread from Mexico to Argentina. Brazil is known to harbor five species belonging to this genus with most of them presenting at head a flattened central tubercle lacking a free apex. However, one of these species, Paxillus macrocerus Reyes-Castillo & Fonseca, differs from that pattern by having a long central tubercle with a completely free apex. The present study describes and illustrates another new species, which has been found in the Brazilian Amazon, showing this same characteristic.
