Solid phase extraction using molecular imprinting polymers (MISPE) for the determination of estrogens in surface water by HPLC

Revista Ambiente & Água, 2017
Estrogens are emerging pollutants and traditional sewage treatments unable to remove them. They are harmful to human health and to the environment. It is therefore important to evaluate the presence and concentration of estrogens in water bodies and ...

Chemical properties and protective effect of Rosmarinus officinalis: mitigation of lipid peroxidation and DNA-damage from arsenic exposure

Journal of Applied Botany and Food Quality, 2018
Recent studies have implicated dietary factors in the cause and prevention of important diseases, with strong evidence that plant’s compounds can protect against these diseases.

Inside a duck‐billed dinosaur: Vertebral bone microstructure of Huallasaurus (Hadrosauridae), Upper Cretaceous of Patagonia

The Anatomical Record, EarlyView.
Abstract Dinosaurs evolved a unique respiratory system with air sacs that contributed to their evolutionary success. Postcranial skeletal pneumaticity (PSP) has been used to infer the presence of air sac systems in some fossil archosaurs. While unambiguous evidence of PSP is well documented in pterosaurs and post‐Carnian saurischians, it remains absent

Widespread distribution of large silesaurids evidenced by a new record from the Middle Triassic of southwest Gondwana

The Anatomical Record, EarlyView.
The largest silesaurid known from South America is described here, demonstrating that silesaurids reached large body sizes in southwestern Gondwana. This discovery further underscores the widespread geographic distribution and temporal persistence of large silesaurids across Pangea, despite faunal turnovers and environmental events such as the Carnian ...

Stereochemical Modulation of Palladacyclopentadienyl Complexes Bearing Diphosphine Ligands: A Key to Enhanced DNA Interaction and Anticancer Activity

European Journal of Inorganic Chemistry, EarlyView.
A modular library of structurally robust palladacyclopentadienyl Pd(II) complexes bearing achiral and chiral diphosphines was developed, revealing a strong influence of diphosphine design and ligand chirality on cytotoxicity and selectivity against ovarian cancer cells, including platinum‐resistant models.

Multiple scales of fear: foraging behaviour of white‐naped jays in semiarid landscapes

Oikos, EarlyView.
Animals must constantly balance the need to find resources with the risk of predation. Not only avoiding direct encounters with predators but also assessing the overall risk of their environment using cues, social information or habitat traits at multiple spatial and temporal scales.

Balancing tracks and trees: Assessing railroad impact on Brazilian biodiversity

PLANTS, PEOPLE, PLANET, EarlyView.
The Brazilian West–East Integration Railway (FIOL) aims to boost the national economy by improving commodity transport; however, it crosses three of Brazil's most biodiverse and fragile regions: the Caatinga, Cerrado and Atlantic Forest. Using digitised plant records and land‐use analyses, our study reveals significant vegetation loss within the ...

Comparação entre metodologias de amostragem de água para quantificação de variáveis limnológicas em ambiente lótico

Revista Ambiente & Água, 2017
Objetivou-se, com o presente trabalho, avaliar duas metodologias de amostragem de água (amostra coletada na profundidade de 15-30 cm e amostra integrada), para determinação de variáveis limnológicas em uma seção transversal do rio Catolé Grande, em ...

Development of Microsatellite Markers for Ex Situ Management of the Harpy Eagle Using Next Generation Sequencing

Zoo Biology, EarlyView.
ABSTRACT The Harpy Eagle (Harpia harpyja), one of the largest birds of prey in the world, is threatened with extinction throughout its entire area of occurrence in the Neotropics. While conservation efforts for the wild populations are crucial, it is also important to focus on ex situ conservation actions.

Demographic buffering in natural populations: A multi‐level perspective

Journal of Animal Ecology, EarlyView.
We introduce a multi‐level framework that unites stochastic elasticities with nonlinear selection to test demographic buffering. Applying it across mammals reveals a key insight: ecological robustness to variability often decouples from evolutionary constraint, reshaping how we understand resilience under environmental stochasticity.
