Endangered flora in protected areas of Rio de Janeiro municipality ­ Rio de Janeiro State, Brazil

This study presents a qualitative analysis of endangered species occurrences in conservation units of Rio de Janeiro, one of the largest Brazilian municipalities in population size. Increasing human activities trigger changes in biodiversity, promote fragmentation, and reduce species distribution ranges, which can ultimately lead to declines in population sizes. One of the main goals of protected areas (PAs), such as conservation units, is to protect and conserve biodiversity. Here, we compiled all vascular plant species recorded within Rio de Janeiro PAs by consulting the Reference Center for Environmental Information (SpeciesLink), Flora do Brasil (2020), and primary data records contained in management plans. We compared this compilation with the list of Brazilian endangered plant species, verifying whether the management plans presented specific programs for these species. Of the 60 surveyed PAs, 24 had records of endangered species and only 17 had management plans, 14 of which had a specific program that contemplated the monitoring and/or conservation of endangered species. A total of 70 endangered species were recorded. The highest numbers of endangered species were found in the Tijuca National Park (41) and the Pedra Branca State Park (17), the two largest PAs with the two largest forest fragments. Despite the high number of endangered species and the number of protected areas that harbor them, few internal programs address endangered species conservation and management. Thus, efforts to maintain endangered species in protected areas can be aided by field data collections that confirm their occurrence and maintenance in these PAs.(AU)

Cave-dwelling gastropods (Mollusca: Gastropoda) of Brazil, state of the art and conservation: a critical review

In 2022, Salvador and co-authors published an up-to-date list of gastropod species recorded from Brazilian caves. That list included 18 species (15 land and three freshwater species) that were considered by the authors to be restricted to caves (troglobitic). In this contribution we argue that only six of the species listed by them as truly troglobites can be classified in that category. We disagree with some characteristics listed by Salvador and co-authors to diagnose the species they classify as cave-restricted and argue that those species do not have truly troglomorphic traits (characteristic of subterranean habitats). Since the Brazilian legislation considers the degree of association with caves as a decisive attribute to preserve them, it is important to clarify the characteristics are sufficient and necessary for a species to be classified as cave-dependent.

Odonata community in transition areas between Cerrado and Atlantic Forest biomes in south-central Minas Gerais, Brazil

Faunal inventories are essential for biota management and conservation, especially in areas with potential for the creation of conservation units. Inventories of insect taxa such as dragonflies and damselflies (Odonata), which perform several environmental services in aquatic and terrestrial ecosystems, are of great importance. In view of the above, this study aimed to update and expand the list of Odonata species in the Barroso region, Minas Gerais State, Brazil. This study was carried out in three areas of forest fragments in Atlantic Forest and Cerrado biomes in October 2020, December 2020, January 2021, and March 2021. The sampling effort was 8 hours per day during 20 days, totaling 140 sampling hours. A total of 43 Odonata species were recorded, which increased the richness of the study area from 57 to 76 species. The studied areas harbor rare and endangered species. However, since the last sampling in 2009, there has been a significant reduction in diversity in the Atlantic Forest fragment. In view of the changes that forest fragments are undergoing, we underscore the need to create a conservation unit, especially in Baú Forest.(AU)

Reprodução de procionídeos / Procyonids reproduction

Poucas informações a respeito da biologia dos procionídeos estão disponíveis para quem busca conhecer mais sobre essas espécies. Entretanto, alguns estudos a respeito da reprodução destes animais foram realizados. As principais espécies encontradas no Brasil são o quati, o guaxinim e o jupará, e, dentre esses, o quati se destaca por ser o que possui o maior número de informações reprodutivas. A maioria dos procionídeos aparece como espécies não ameaçadas, porém a falta de informações sobre estes animais pode fazer com que estes dados possam estar defasados. É importante o conhecimento reprodutivo dos procionídeos pois, devido as ações antrópicas que ocasionam a perda de habitat natural, essas espécies, em breve, podem entrar para a lista de animais ameaçados de extinção. Assim, esse artigo tem como objetivo descrever alguns dados por meios de estudos reprodutivos que podem auxiliar ao desenvolvimento de estratégias de conservação dessas espécies.(AU)

Little information about the biology of procyonids is available for those who want to know more about these species. However, some studies regarding the reproduction of these animals were developed. The main species found in Brazil are coati, raccoon, and kinkajou, among which the coati stands out for being the one with the highest number of reproductive information. Most procyonids appear as non-threatened species, but the lack of information about these animals may cause these data to be outdated. Reproductive knowledge of procyonids is important because, due to anthropic actions that cause loss of natural habitat, these species may soon enter on the list of endangered animals. Thus, this article aims to describe some data by means of reproductive studies that can help to develop conservation strategies for these species.(AU)

Abdominal ultrasound in amazonian manatee (Trichechus inunguis) (Natterer, 1883)

Abstract Morphophysiological species researches are fundamental, and diagnostic imaging is an excellent technique, already used in wild animals, with great application, not invasive and provide real-time information of each body. Amazonian manatees are on the list of endangered animals classified in the vulnerable category and knowledge of the normal pattern of ultrasound anatomy of organs and tissues is important for the maintenance and well-being of captive specimens contributing to reintroduction actions. The objective of the study was to standardize the examination technique and describe the ultrasound findings of the liver, gallbladder, stomach, urinary bladder and the subcutaneous tissue of the abdominal region in Trichechus inunguis, in order to contribute with the anatomical and sonographic knowledge and assist in the diagnosis and prognosis diseases. The study used 18 animals to describe the normal sonographic anatomy in the abdominal cavity of the Amazonian manatee. During abdominal scan, it was possible to visualize the features of the liver, gallbladder, stomach, urinary bladder obtained satisfactory results in this study. Therefore, other structures were not primarily identified by the reduced time, lots of fat and gases in intestines of animals.

Medium and large sized mammals and the effect of habitat heterogeneity from a Caatinga shrubby forest at Serra de Santa Catarina, Paraíba, Brazil

In xeric environments, such as Caatinga Biome, habitat characteristics such as phytophysiognomy type and presence of water bodies can represent higher resource availability. In this context, the present study investigated the effect of phytophysiognomies and presence of water bodies in the abundance and community structure of medium and large mammal species (MLM) in the Serra de Santa Catarina, Paraíba, Brazil. To evaluate these variables we conduct an effort of 373 camera-trap days, between August 2012 and November 2014. We recorded 12 MLM species, distributed in six orders and 11 families. From those, Kerodon rupestris is the only one listed in the Brazilian List of Threatened Fauna. Regarding the habitat, the Mann-Whitney showed a significant higher frequency to the Shrubby habitat and the ANOSIM showed no shifts in the community structure between Arboreal and Shrubby. Concerning the presence of water bodies, both the Mann-Whitney and the ANOSIM showed significant higher frequency to the habitat with water presence. We observed that both phytophysiognomy and water bodies are important variables which affect mainly the abundance of mammalian species from semiarid environments. Nonetheless, whereas the forest remnants get smaller the existence of water bodies becomes a preponderant factor to the MLM species and its community structure.(AU)

Microbiological featuring of two neotropical fish species from the quilombola area of maranhão state, Brazil / Caracterização microbiológica de duas espécies de peixes neotropicais oriundas de área quilombola maranhense, Brasil

The aim of study is to feature the microbiological quality of two neotropical fish species from the quilombola area of Maranhão State, Brazil. In order to do so, 21 samples of Hoplerythrinus unitaeniatus and 21 samples of Cichlasoma bimaculatum were captured in flooded environment. Collected fish were euthanized in laboratory environment; muscle fragments were removed for microbiological analyses focused on enumerating molds and yeasts, viable strict and facultative mesophilic microorganisms and coagulase-positive staphylococci; on counting total and thermotolerant coliforms; and on investigating Escherichia coli and Salmonella sp. Microbiological results were compared to the Brazilian legislation, which establishes the list of microbiological standards for food products. Among the assessed fish, 9.52% were classified as non-acceptable for human consumption, based on the Salmonella parameter. Enumerated coagulase-positive staphylococci ranged from < 10 to 3.9 x 104 CFU/g; 9.52% of assessed fish were classified as having intermediate standard for human consumption, whereas 4.76% were classified as non-acceptable for such a purpose. E. coli counting ranged from 3.6 to > 1,100MPN/g; 4.76% of assessed fish were classified as having intermediate standard for human consumption, whereas 4.76% were classified as non-acceptable for such a purpose. Total and thermotolerant coliforms' counting and the enumeration of viable strict and facultative aerobic microorganisms, as well as of molds and yeasts, have evidenced high microbial population rates; this finding suggests poor hygienic conditions at capture site, contaminated raw material and risk of incidence of enteropathogens. This finding has evidenced imbalance in the investigated environment, as well as compromised aquatic biodiversity.(AU)

Objetivou-se caracterizar a qualidade microbiológica de duas espécies de peixes neotropicais oriundas de área qui-lombola maranhense, Brasil. Para isso, foram capturadas 21 amostras de Hoplerythrinus unitaeniatus e 21 amostras de Cichlasoma bimaculatum de ambiente alagável. No laboratório, os peixes foram eutanasiados, procedida a retirada dos fragmentos mus-culares e realizada as análises microbiológicas: enumeração de bolores e leveduras, micro-organismos mesófilos aeróbios estri-tos e facultativos viáveis e de estafilococos coagulase positiva, quantificação de coliformes totais e termotolerantes, pesquisa de Escherichia coli e Salmonella sp. Os resultados microbiológicos obtidos foram comparados com a legislação brasileira que estabelece a lista de padrões microbiológicos para alimentos. Dos peixes avaliados, 9,52% foram considerados inaceitáveis para consumo humano para o parâmetro Salmonella. A enumeração de estafilococos coagulase positivavariou de <10 a 3,9 x 104 UFC/g, sendo 9,52% dos peixes considerados com padrão intermediário e 4,76% inaceitáveis para consumo. A quanti-ficação de E. coli variou de 3,6 a >1.100 NMP/g, sendo 4,76% considerados com padrão intermediário e 4,76% inaceitáveis para consumo. A quantificação de coliformes totais e termotolerantes e a enumeração de micro-organismos aeróbios estritos e facultativos viáveis e bolores e leveduras revelou elevadas populações microbianas o que sugere más condições higiênicas do local de captura, matéria-prima contaminada e risco da presença de enteropatógenos, demonstrando desequilíbrio no ambiente estudado com comprometimento da biodiversidade aquática.(AU)

Pyometra in a tiger (Panthera tigris)

Background: Captive tigers can live a long life, around 26 years. Among the diseases described some of non-infectious origin are quite common, such as chronic kidney disease, spondylosis, and biliary cysts or tumors. On the other hand, pyometra has been frequently reported in lions, who have a higher risk of developing the disease than tigers and leopards. Pyometra is a disease with few descriptions in tigers and it may be related to the physiological features of the species. The animal is listed as Endangered on the International Union for the Conservation of Nature Red List of Threatened. The present report aims to describe the diagnosis and treatment of pyometra in a captive tigress. Case: A 7-year-old entire female tiger (Panthera tigris) weighing 140 kg was presented with a 3-day history of anorexia and prostration. For clinical examinations, collection of laboratory and imaging tests, the patient initially underwent dissociative anesthesia to allow catheterization of the cephalic vein and intravenous general anesthesia for orotracheal intubation followed by anesthetic maintenance in isoflurane. On general physical examination, the animal had normal colored mucosa, vital parameters within normal limits, and a body condition score of 6 on a scale of 9. There was no presence of vulvar secretion. The blood count and the biochemical exams showed values within the normal range for the species. The chest X-ray in the right and left views did not demonstrate pulmonary abnormalities. Ultrasonographic examination of the abdomen showed distension of the uterine body and horns, which have intraluminal hyperechoic fluid content without flocculation. Based on the imaging exam, the diagnosis was suggestive of pyometra. Exploratory celiotomy was performed via ventral midline, confirming the condition, which was treated by ovariohysterectomy. The surgical technique was performed as described for therapeutic ovariohysterectomy in dogs and cats. Culture of uterine content identified Escherichia coli. The histological analysis identified diffuse endometritis associated with follicular cysts. The tiger had complete recovery without any complications. The patient was releasing 13 days after the surgical procedure and in the last contact four months after the surgery, it was in perfect health conditions. Discussion: Pyometra in large exotic felids has been occasionally reported, mainly in animals more than 10 years of age. Although the tigress in the report is estimated to be seven years old. The patient in question started with anorexia and prostration and as there was already a history of cystic endometrial hyperplasia, a possible pyometra was suspected, despite being uncommon in the species. There was not vaginal discharge. The definitive diagnosis was by means of ultrasound examination and ovariohysterectomy was performed. Abdominal surgery for these large felids is complex, due to the intra-abdominal volume the flank approach or by laparoscopic is suggested, however in this case a ventral midline incision was performed without intercurrences and complications in the post-operative period. The surgical technique like that used in small animals was effective for the treatment of pyometra in the tigress with the use of ovariohysterectomy. Culture of uterine content identified Escherichia coli, which has been the most commonly isolated pathogen in pyometra of large felids. It was concluded that, as in bitches with pyometra, early diagnosis and surgical treatment is ideal for the patient's recovery.

Colheita de sêmen e inseminação artificial em onças-pintadas (Panthera onca) / Semen collection and artificial insemination in jaguars (Panthera onca)

A onça-pintada encontra-se classificada como "quase ameaçada" na lista vermelha de animais ameaçados da União Internacional para Conservação da Natureza (IUCN), com tendência ao declínio na América Latina, o que pode afetar o fluxo gênico elevando o risco de endogamia. Técnicas de reprodução assistida (TRAs) como colheita de sêmen e inseminação artificial (IA), são ferramentas que podem se tornar essenciais a manutenção da diversidade genética desses animais. A colheita de sêmen pode ser realizada por eletroejaculação (EEJ) ou colheita farmacológica (CF), sendo que podem ser aplicadas individualmente ou associadas, embora EEJ tenha se mostrado mais eficiente em inseminação artificial (IA) com sêmen a fresco. Para realização de IA a utilização de progestina oral (altrenogest), seguida da aplicação de gonadotropinas exógenas (Gonadotropina Coriônica equina-eCG e Hormônio Luteinizante suíno-pLH), tem se mostrado eficiente, promovendo ovulações consistentes. IA intratubárica (IA-IT) mostrou-se eficiente, tendo a vantagem de utilizar sêmen com baixo número de espermatozoides. O sucesso alcançado com o nascimento do primeiro filhote de Panthera onca utilizando TRAs se deve a vários fatores, dentre eles, a utilização de um novo protocolo hormonal ajustado à espécie; e a utilização da IA-IT, que possibilitou a utilização de sêmen com reduzido número de espermatozoides viáveis por inseminação.(AU)

The jaguar is classified as "near threatened" according International Union for Conservation of Nature red list, with a decreasing trend in the population of Latin America, increasing the risk of inbreeding. Assisted reproduction techniques (ARTs), such as semen collection and artificial insemination (AI), are tools that can become essential to maintain the genetic diversity of jaguars. Semen collection can be performed by electroejaculation (EEJ) or pharmacological collection (PC); and can be applied individually or associated, however EEJ was more efficient for artificial insemination (AI) with fresh semen. To perform Artificial Insemination (AI), oral progestin (altrenogest) followed exogenous gonadotropins (Gonadotropin Chorionic equine-eCG e Hormone Luteinizing porcine-pLH) application was efficient, promoting consistent ovulations. Similarly, laparoscopic oviductal insemination (IA-IT) was efficient, with the advantage to use low viable spermatozoa number by insemination. The success of jaguar cub birth using ARTs is due to several factors, among than, a new hormonal protocol adjusted to the species; and the use of IA-IT, which allowed the reduction in the number of sperm by insemination.(AU)

Avifauna of the Serra de Itabaiana National Park revisited: additions and deletions in a period of 15 years

The Serra de Itabaiana National Park (PARNASI) is known as an important conservation area in the ecotone between the Atlantic Forest and Caatinga in Northeast Brazil and is one of the main areas of fauna and flora studies in Sergipe. For this reason, there are some studies on its avifauna, which date back to its creation in 2005. However, after 15 years of establishment of PARNASI, an update of the inventory of birds is necessary due to adjustments in the management of the park. The present study aimed to update the bird inventory of the Serra de Itabaiana National Park, chronologically comparing the new ornithological records obtained, aiming to contribute to the knowledge and conservation of Sergipe's avifauna. The data were compiled from scientific publications, personal files and from documented records on a specialized website. The resulting list includes 227 bird species belonging to 49 families, including Thraupidae (28 species; 12.4%), Tyrannidae (25 species; 11.1%) and Accipitridae (17 species; 7.5%) as the most representative. The most representative guilds were insectivorous (87 species; 38.3%) and omnivorous (60 species; 26.4%), and by species independent of the forest environment (87 species; 38.3%). Fourteen bird species are threatened with extinction. Nine species are endemic to the Caatinga biome, eight to the Atlantic Forest and one to the Cerrado. We added 104 species to the first checklist produced for the PARNASI created in 2005, including Nyctibius grandis (Nyctibiidae), a new record for the state of Sergipe. PARNASI's updated list of bird species allows for a better assessment of its effectiveness in the conservation of the local avifauna, facilitating management actions that allow the coexistence and perpetuation of species over time.(AU)

High richness of non-volant mammals in a seasonal forest fragment in southeastern Brazil

The seasonal forest formations of the Atlantic Forest are a threatened and poorly known habitat. We present here a list of the non-volant mammals occurring in a 515­ha forest fragment known as Santa Maria and located in the Brazilian state of São Paulo. Our surveys are based on live trap captures, camera traps, and active searches for footprints, as well as secondary data. We list 29 species of non-volant mammals in the fragment, recorded between 1996 and 2021. One species found in the fragment, Leontopithecus chrysopygus, is globally endangered. Two species are classified as "vulnerable" in the global red list: Myrmecophaga tridactyla, and Tapirus terresris. One species, Panthera onca, is classified as "critically endangered" in São Paulo state. The red howler, Alouatta guariba, was not recorded after 1999 and has probably been extirpated in the fragment. We show that the number of non-volant mammal species in Santa Maria fragment is high, in relation to its size. The fragment is also in a strategic position, between the Morro do Diabo state park and the Black Lion Tamarin Ecological station, the two largest protected areas in the region. Considering its high mammal richness and its possible role as stepping stone for the local fauna, we recommend that the fragment become a protected area.(AU)

Checklist of the birds of Mato Grosso do Sul state, Brazil: diversity and conservation

Several phytogeographic regions (Cerrado, Pantanal, Atlantic Forest, Gran Chaco, and Chiquitano Dry Forests) converge in the state of Mato Grosso do Sul, Brazil, and influence regional biodiversity. Despite a list of birds in the state of Mato Grosso do Sul being published by Nunes et al. (2017), it is necessary to update and critically review avifauna records. In this study, we gathered the results of several records obtained from species lists and online data platforms of the 336 sites in this state over the last decades and grouped them into Main (Primary and Secondary) and Tertiary Lists. The avifauna of Mato Grosso do Sul is composed of 678 species, of which 643 (95%) have records proving their occurrence (Primary List), whereas 34 still lack documentation (Secondary List). The number of related species for Mato Grosso do Sul represents 34% of the Brazilian avifauna. Some species stand out for their unique occurrence in Mato Grosso do Sul, such as Melanerpes cactorum, Celeus lugubris, Phaethornis subochraceus, and Cantorchilus guarayanus, reflecting the influence of different phytogeographic regions of the Chaco and Chiquitano Dry Forests. Migrants represent 20% of the bird community occurring in the state, of which 93 species correspond to migrants from various regions of South America (south and west) and 40 to boreal migrants. Thirty-three species perform nomadic movements across the Pantanal Plain and other regions of the state. Thirty-one species are included in some conservation-threatened categories of global and/or national endangered species lists. Other 30 species are included in the near-threatened category at the global level and 23 at the national level. In addition, species typical of dry forests (in Serra da Bodoquena and Maciço do Urucum) and those from the Atlantic Forest in the south of the state deserve attention due to their restricted distribution and the high anthropogenic pressure on their habitat.(AU)

First list of parasitoids in flies of medical, veterinary, and forensic importance in Rio Grande do Sul Brazil

Abstract Necrophagous flies are of great importance for human and animal health. In places where their development occurs, parasitoids can be used as a tool to control these dipterans. In Brazil, the fauna of these parasitoids has been investigated in some regions. However, in Rio Grande do Sul, it is known the occurrence of only one species. Thus, this study aimed to create the first list of parasitoids in flies of medical and veterinary importance in Southern Brazil. Collections took place in the municipality of Pelotas (31º 42 S; 52º 18 W). Three replicates consisting of a 500 g bovine liver chunk placed in a tray were exposed to open air for 20 days. Then pupae were individualized and observed until their emergence. We identified 4,882 adult flies of Calliphoridae, Fanniidae, Muscidae, and Sarcophagidae. 4,040 parasitoids emerged, belonging to eight species, of which Nasonia vitripennis, Spalangia cameroni, Spalangia chontalensis, and Tachinephagus zealandicus are new records in Rio Grande do Sul state. Also, three undescribed species of the genus Aphaereta were collected. In spite of being the first attempt to inventory the fauna of hymenopteran parasitoids, this study may help in the development of management programs of these dipterans in the region.

Resumo Moscas necrófagas possuem grande importância para a sanidade humana e animal. Onde estas se desenvolvem ocorrem parasitoides que podem ser utilizados como ferramentas para o controle desses dípteros. No Brasil, a fauna desses parasitoides vem sendo investigada em algumas regiões e no Rio Grande do Sul é conhecida a ocorrência de apenas uma espécie. Portanto, o objetivo deste estudo foi criar a primeira lista de espécies de parasitoides de moscas de importância médica e veterinária ocorrentes no extremo sul do Brasil. As coletas foram realizadas no município de Pelotas (31º 42 S; 52º 18 O). Foram montadas três réplicas de bandejas contendo, cada uma, 500 g de fígado bovino, expostas ao ar livre durante 20 dias. Na sequência, as pupas foram individualizadas e observadas até a emergência. Foram identificados 4.882 adultos pertencentes às famílias Calliphoridae, Fanniidae, Muscidae e Sarcophagidae. Emergiram 4.040 parasitoides, pertencentes a oito espécies, das quais Nasonia vitripennis, Spalangia cameroni, Spalangia chontalensis e Tachinephagus zealandicus são novas ocorrências para o Rio Grande do Sul. Foram coletadas três espécies ainda não descritas do gênero Aphaereta. Apesar de ainda ser um primeiro esforço de inventariar a fauna de himenópteros parasitoides, este estudo pode auxiliar no desenvolvimento de programas de manejos desses dípteros na região.

Cave-dwelling gastropods (Mollusca: Gastropoda) of Brazil: state of the art and conservation

An up-to-date list of exclusively cave-dwelling gastropod species recorded in Brazil is presented including updated taxonomy, detailed geographic information, and illustration of types. The list includes 18 cave-exclusive (troglobitic) gastropods encompassing 15 land and three freshwater species, with the status of further species pending additional studies. Their unusual morphology and diversity are discussed, as well as their conservation status and prospects in the current Brazilian environmental and political scenario.(AU)

New records for the poorly-known monotypic genera Exallostreptus and Guaporeptus, and a list of species from Mato Grosso state, Brazil (Diplopoda: Spirostreptida: Spirostreptidae)

New records for the species Exallostreptus vanzolinii Hoffman, 1988 and Guaporeptus paradisius Hoffman, 1988, known only from the state of Rondônia, are made from the state of Mato Grosso, Brazil. Figures of gonopods, first and second leg-pair of males are provided. In addition, an updated list of 19 Spirostreptidae species from Mato Grosso is provided, with the species Plusioporus salvadorii, Trichogonostreptus (Oreastreptus) mattogrossensis, and Urostreptus tampiitauensis widely distributed in the state.(AU)

Rotifers of Bahia State, Brazil: News records and limitations to studies

Abstract A first checklist of Rotifera species in freshwater environments in Bahia State, in northeastern Brazil, is provided. The list includes sampling data from 26 aquatic environments (lotic and lentic) undertaken from 2010 to 2016. One hundred and fifty-five species were recorded, with 68 new records for the state. The family Brachionidae and Lecanidae were the most representative (54.8%). The greatest richness was recorded in the Colônia River (57 species). Those results reflect the low numbers of studies previously undertaken in the region, indicating more research needs to be focused on Rotifera biodiversity in Bahia, the fifth largest state in Brazil (567,295 km2) with large numbers of freshwater bodies.

Resumo É fornecida uma primeira lista de verificação das espécies de Rotifera em ambientes de água doce no Estado da Bahia, nordeste do Brasil. A lista de espécies inclui dados de amostragem de 26 ambientes aquáticos (lóticos e lênticos) de 2010 a 2016. Cento e cinquenta e cinco espécies foram registradas, com 68 novos registros para o estado. As famílias Brachionidae e Lecanidae foram as mais representativas (54,8%). A maior riqueza foi registrada no rio Colônia (57 espécies). Esses resultados provavelmente refletem o número de estudos na região, sugerindo mais pesquisas sobre a biodiversidade de Rotifera na Bahia, o quinto maior estado do Brasil (567.295 km2) com grande número de corpos aquáticos de água doce.
