Understanding the interaction between groundwater and surface water is crucial for an effective management. This study investigates vertical variability of radon gas (Rn-222) concentrations other physicochemical parameters (pH, electrical conductivity, redox potential, temperature) in artificial lake (Aguieira Dam's reservoir) Mondego River, Portugal, that intensively controlled by human factors. Over nine surveys conducted from May 2022 to September 2023, we observed significant temporal...
ABSTRACT Ecological release is a key concept that describes how species increase their density and expand niche in response to reduced competition. This phenomenon commonly studied island systems, but its occurrence naturally isolated habitats within continents remains underexplored. To address this gap, we compared lizard assemblages between the remnants of coastal Atlantic Forest (non‐isolated areas) forest relicts. Our predictions were areas, dimensions (e.g., diet) should be larger due...
Abstract Ecological characteristics and environmental variation influence both host species composition parasite abundance. Abiotic factors such as rainfall temperature can improve development increase its reproduction rate. The comparison of these assemblages between different environments may give us a more refined analysis how environment affects the helminth aim present study was to evaluate temporal variation, size, sex affect abundance in Tropidurus hispidus lizard Caatinga, Restinga...
Context: Ethnozoological studies have shown that Spilotes pullatus Linn. (Colubridae: Ophidia), is associated with medicinal and magic-religious uses in Brazil.Objectives: This study was designed to determine the chemical composition of oil extracted from body fat S. test its antimicrobial properties, alone association aminoglycosides, against fungi bacterial strains concentrations ranging between 1024 0.5 µg/mL.Material methods: The snakes were collected Chapada do Araripe, county Crato,...
Abstract We investigated the parasites of five lizard species belonging to Phyllodactylidae (Phyllopezus pollicaris and Gymnodactylus geckoides) Gekkonidae (Hemidactylus agrius, Lygodactylus klugei Hemidactylus brasilianus) families in a semiarid region Brazil. Six nematode were identified: Parapharyngodon alvarengai Spauligodon oxkutzcabiensis (Pharyngodonidae), Physaloptera lutzi (Physalopteridae), Skrjabinelazia intermedia (Seuratidae), Trichospirura sp. (Rhabdochonidae) Piratuba...
We examined 31 specimens of Rhinella granulosa from the semiarid Caatinga region northeastern Brazil for presence gastrointestinal nematodes. found 7 nematode taxa: Rhabdias androgyna, Raillietnema spectans, Aplectana membranosa, Oswaldocruzia sp., Physaloptera and cosmocercidae larvae. The total prevalence was 25.8% by mean intensity infection (± SD) 50 ± 7.36. in males 10% with an 4 while females it 42.85% a 42 8.55. juveniles presented 14.28% 4. represents new host following nematodes: sp.
Abstract The distribution of parasites within host populations and communities, the mechanisms responsible for these patterns, are poorly understood aspects wildlife parasitology. Here, we evaluate influence average abundance endoparasite variance, using endoparasites lizards from Caatinga domain (semiarid region), north-eastern Brazil. We hypothesized that, due to high number generalist species, they may occur randomly throughout in an aggregate pattern. In addition, evaluated degree which...
Summary We tested the role of sex, size, and mass lizards Phyllopezus pollicaris , Gymnodactylus geckoides Hemidactylus agrius Lygodactylus klugei brasilianus on rates pentastomid infection in Brazilian Caatinga. collected 355 individuals these five species, which four (prevalence infection: P. 15.9 %, G. 1.4 H. 28.57 4.16 %) were infected by Raillietiella mottae . Parasite abundance was influenced host body size only Host sex did not influence parasites any species. are three new records...
The parasitic fauna of reptiles is considered understudied compared to that other vertebrates and even less well known than the chelonians. Yet parasites are one main controllers host populations because they can strongly impact population structure species diversity. objective present study was identify helminth infecting freshwater turtles Phrynops geoffroanus Mesoclemmys tuberculata, evaluate effects features (body mass sex) seasonality (dry rainy seasons) on abundance parasites, compare...
We identified Miranda's white-lipped frog ( Leptodactylus macrosternum) as a new host for chiggers Hannemania sp.). A total of 57 larvae sp. were found on 31 frogs examined from semiarid region northeastern Brazil.
