Effect of slaughter weights on some meat quality traits of Santa Inês lambs in a feedlot

Context The growing demand for more tender and healthy meat requires more precise parameters. Therefore, defining the ideal slaughter weight for sheep is crucial to strike a balance between productive performance and meat quality. Aims In this context, we aimed to evaluate the ef...

Functional trait space overlaps reveal ecological resilience of bird communities in Atlantic Forest fragments

While fragmentation is known to affect species diversity, the degree to which functional structure is retained relative to primary forests and the factors driving this retention remain poorly understood. Here, we applied the concept of ecological resilience to forest fragmentatio...

Parasitic fauna in the invasive lizard Hemidactylus mabouia (acertilia: ekkonidae), in anthropized environments of astern razilian mazon

Abstract This study characterizes the structure and ecological patterns of the endoparasite community associated with the exotic lizard Hemidactylus mabouia in three municipalities in western Pará, Brazil. A total of 156 individuals were examined, of which 71.15% (CI 63.49–77.95)...

A random forest isoscape model of bioavailable Sr for South America: a focus on southern Brazil

In recent years, advances in machine learning have greatly improved the generation of maps showing the geographic distribution of isotope ratios (isoscapes), which have become essential tools for environmental, mobility and provenance studies in both modern and archaeological con...

A cytogenetic analysis with chromosome painting in typical antbirds (Passeriformes, Thamnophilidae) and an inference on chromosome evolution in Passeriformes

Abstract The typical antbirds (Passeriformes, Thamnophilidae) are a monophyletic group comprising 225 species in 45 genera, primarily distributed in the lowland forests of the Neotropics. There is limited karyotypic information for this bird family, including chromosome morpholog...

From glow to risk: degree of exposure of Arctiinae moths (Lepidoptera: Erebidae) to light pollution in the Neotropics

Abstract The accelerated decline of insects is driven by anthropogenic pressures such as habitat loss, pesticide use, and climate change. Species vulnerability varies according to their exposure, sensitivity, and adaptive capacity to these threats. Artificial light at night (ALAN...

Adsorption of Pharmaceutical Contaminants from a Real Hospital Effluent Using Acai Biomass-Derived Biochar Modified via Magnetron Sputtering

Abstract A novel aluminum-coated biochar derived from açaí waste was successfully engineered via physical vapor deposition (magnetron sputtering) to remove the emerging pharmaceutical contaminants clorazepate (Clz) and diclofenac (Dic) from synthetic and real aqueous systems. A...
