Researchers in the Global South (GS, developing countries) make valuable contributions to field of comparative physiology, but face economic and scientific disparities several unique challenges compared with colleagues North (developed countries). This Perspective highlights some challenges, knowledge gaps opportunity faced by GS researchers, especially those at early-career stages. We propose collaborative solutions help address these issues, advocate for promoting investment cultural...
The Araguaia River dolphin is endemic to the Tocantins-Araguaia Basin and under severe anthropogenic threats. Given species’ vulnerability historical neglect, preliminary data on its health physical parameters are presented, along with an evaluation of potential differences between individuals from areas varying human activity. A comparison these closely related species, Amazon I. geoffrensis , was also aimed. Twenty-four dolphins were captured released in Cantão State Park (protected area,...
In the last decades, knowledge about biology of Amazon river dolphin Inia geoffrensis has increased considerably. Accordingly, we present a review published literature on this dolphin, with focus topics most advancements and those that are important to species conservation. We also new information, including emerging other Inia. summarize current Inia, covering aspects taxonomy, distribution, life history reproduction, genetics, anatomy physiology, health, behavior, ecology, demographic...
The last relevant work that reviewed the biological and conservation aspects of Amazonian manatee (Trichechus inunguis) was published almost 30 years ago. In these three decades, scientific knowledge about species has advanced substantially. This review article updates various manatee, summarizing information present in literature. Topics such as morphology, habitat, distribution, population aspects, food feedings habits, reproduction, behavior, health, threats, status, efforts were...
ABSTRACT: The Amazonian manatee (Trichechusinunguis) is an aquatic mammal threatened with extinction. However, few studies have investigated the pathogens in this species, which may affect both animal and human health. This study aimed to evaluate frequency, distribution, patterns of antimicrobial susceptibility Staphylococcus spp. Escherichiacoli colonizing nasal rectal cavities manatees kept captivity at National Institute for Research (INPA) state Amazonas, Brazil. Rectal swabs from 44...
Abstract Monitoring reproductive rates in wild cetaceans is a crucial step towards adequate management of their populations. Their hormone profiles can be importance, especially when combined with behavioural or life history monitoring. Sampling biological matrices wild, free‐ranging difficult task. The purposes this review are: to describe briefly the different methods available for monitoring endocrine parameters and captive cetaceans, evaluate feasibility using various – blood, urine,...
The present study characterized the filamentous and yeast-like fungal microbiota of nasal cavity rectum Amazonian manatees (Trichechus inunguis) undergoing rehabilitation at Laboratory Aquatic Mammals, National Institute Research, Manaus, Amazonas, determined antifungal susceptibility these organisms. Nasal rectal swabs were collected from 22 calves three juveniles. samples seeded in Sabouraud agar supplemented with chloramphenicol 10%, incubated 26°C, observed daily for up to 7 d. growth...
Among pinnipeds, four Otariidae species (eared seals) have been reported as occasional or frequent vagrants along the coast of Brazil, mainly in southern region. These animals usually arrive debilitated during winter and are directed to rehabilitation. Nevertheless, available information on sanitary aspects stranded pinnipeds Brazil is limited. Increased fur seal strandings (n=23) were recorded 2018 season southeast (Iguape, Ilha Comprida, do Cardoso, Sao Paulo State) compared 2017 (n=2). Of...
Abstract Hemotropic Mycoplasma spp. (hemoplasmas) are uncultivable bacteria that infect mammals, including humans. We detected a potentially novel hemoplasma species in blood samples from wild river dolphins the Amazon River Basin, Brazil. Further investigation could determine pathogenicity and zoonotic potential of hemoplasma.
We assessed the health status and hematologic blood chemistry values of 48 juvenile green turtles ( Chelonia mydas) on southeastern coast Brazil (25°S 48°W). investigated impact size weight, nutritional condition, presence epibionts fibropapilloma tumors. Nutritional was good for 39 animals; these animals had higher serum albumin, cholesterol, phosphorus concentrations than 9 with a fair score. Reference hematology biochemistry were calculated individuals without fibropapillomas (FPs)....
Hematological values are of primary importance when investigating the health and physiological status populations as they reflect biological equilibrium aquatic ecosystems. The objectives this study to produce baseline for hematological parameters Amazon River dolphin (Inia geoffrensis), well investigate significant variations according sex, age, reproductive stress level. One-hundred-and-ten dolphins from Mamirauá Sustainable Development Reserve (3°3'S, 64°51'W), Central Amazon, Brazil,...
Background: Establishment of reference values for serum biochemical analytes is important monitoring health and physiological status captive animals. Objective: The purpose this study was to measure report ranges in Amazonian manatees ( Trichechus inunguis ). Methods: Blood samples were collected from 24 healthy that comprised a mixture adults, subadults, calves males females; measured analyzed using dry reagent bench‐top chemical analyzer. Comparisons made between sexes with previously...
Abstract Blood values of wild cetacean population are a valuable tool to drive proper management threatened species. Reference intervals 26 serum analytes were determined from 107 apparently healthy Amazon river dolphins ( Inia geoffrensis ) wild‐caught in the Mamirauá Sustainable Development Reserve (3°3′S, 64°51′W), central Amazon, Brazil. No differences detected between males and females or pregnant nonpregnant females. Calves had higher calcium than juveniles adults, alkaline phosphatase...
Evaluating renal function is essential for managing captive wild animals, particularly threatened species like the Amazonian manatee (Trichechus inunguis) in rehabilitation and prerelease programs. A series of urine diagnostic tests, such as gross appearance, semiquantitative chemical analyses, microscopic review sediments, quantitative analyses urea creatinine, were performed 57 free-catch samples. On same occasion, 52 serum samples from individuals analyzed creatine kinase activity, blood...
This study is part of the Projeto de Monitoramento Praia– Bacia Santos - (PMP-BS, Basin Beach Monitoring Project) and based on data from stranded cetaceans collected during beach monitoring in state São Paulo, between 2017 2021. Our aim was to assess temporal spatial patterns strandings, including main recorded species, stranding locations, their distribution throughout year. The analysis covered 258 beaches along coast which divided into three mesoregions: South Coast (LSP), Central (LCP),...
Blood analysis is a valuable tool that routinely applied in assessing the health and physiological status of freeranging animals (Borjesson et al., 2000).However, very few hematological studies have been performed on wild cetaceans, at least partially because major logistical difficulties obtaining samples from such large, mobile, wholly aquatic (St. Aubin 2000).Accidental or intentional entrapments by commercial fishing industry has granted some opportunities to collect examine blood harbor...
The use of alternative therapeutic approaches in wild animals has gained notoriety due to its efficiency, low cost and reduced or nonexistent stressors. present study evaluated the efficacy treatment a bilateral excoriative lesion region dorsal metacarpus Chilean skua (Catharacta chilensis) rehabilitation process with porous cell membrane, sold commercially, concomitance moxibustion sessions herbs (Artemisia vulgaris). healing time 14 days was when compared traditional techniques proved...
