The stingrays Potamotrygon amandae and Potamotrygon falkneri are nonnative species established in the Upper Paraná basin. Although they are widely distributed, few studies on their diets or respective metabolic responses ... -
Leaching of benzimidazole antiparasitics in soil columns and in soil columns amended with sheep excreta
; Pinheiro, Rafael Silvio Bonilha; (Environmental Science and Pollution Research, 2020) [Artigo]
Benzimidazoles are anthelmintics frequently used in sheep farming due to the high susceptibility of these animals to parasitic diseases. Sheep excreta are often disposed onto soils as a fertilizer, and they may contain ... -
Climbing plants of a semideciduous seasonal forest remnant in southeastern Brazil
; Castello, Ana Carolina Devides; Rezende, Andréia Alves ; Koch, Ingrid (Rodriguesia, 2019) [Artigo]
Climbing plants play an important role on the dynamics of forest communities and are important as a source of food for wildlife. In this study we characterized these plants in a semideciduous seasonal forest (FES) and ... -
Thermal ecology, activity pattern, habitat, and microhabitats used by the skink Mabuya arajara (Squamata: Scincidae) in the Araripe Plateau, northeastern Brazil
; ; ; ; Anjos, Luciano Alves dos; (Journal of Natural History, 2019) [Artigo]
We evaluated the activity period, thermal ecology, habitats, and preference for microhabitats of the skink Mabuya arajara in a humid forest environment on the slope of the Araripe Plateau, Brazil. A total of 283 lizards ... -
How epidemiological patterns shift across populations in an exotic lizard
; ; ; ; Anjos, L. A.; (Journal of helminthology, 2019) [Artigo]
Several factors influence the dynamics and structure of parasite communities. Our goal was to investigate how the community composition, prevalence and abundance of parasites change across seven populations of the exotic ... -
