Establishing an Ecuadorian Isoscape: The Importance of Baseline Strontium Data in a Volcanic Landscape. [PDF]

Am J Biol Anthropol
ABSTRACT Objectives Strontium isotopes (87Sr/86Sr) have been used worldwide to track migrations and identify nonlocal individuals in the past. In South America, these studies often use comparative baseline maps, or isoscapes, established by samples from archaeological fauna and geologic formations. However, baseline research has focused on coastal Peru

Human land-use changes the diets of sympatric native and invasive mammal species. [PDF]

Ecol Evol, 2023
We simultaneously study the diet of nine native and two invasive mammal species inhabiting three different anthropogenic land‐uses across six bioclimatic regions using environmental DNA and stable isotope analysis. We show that land‐use influences the trophic relationships in invaded communities.

Environmental and human factors shape the trophic ecology of a widespread marine predator. [PDF]

J Anim Ecol
Our study reveals how environmental factors and fishing pressure influence swordfish diet, highlighting trophic shifts under future climate scenarios. We provide a novel framework to strengthen our ability to plan for and manage the redistribution of species under global change ensuring that the energetic needs of predators are met.

Chromosomal Inversion Associated With Diet Differences in Common Quails Sharing Wintering Grounds. [PDF]

Ecol Evol
A large chromosomal inversion in common quails (Coturnix coturnix) is associated with phenotypic traits. In a wintering population in southern Spain, we found all three karyotypes coexisting but showing differences in migratory behavior and diet, as exemplified by the isotopic signature.

Hydroethanolic Extract of Solanum paniculatum L. Fruits Modulates ROS and Cytokine in Human Cell Lines. [PDF]

Oxid Med Cell Longev, 2020
Solanum paniculatum L. or popularly known as “jurubeba” is an herbal medicinal plant. A few studies have investigated its biological effects; however, research aimed at elucidating the redox balance effects from its fruits has not been reported so far. ROS interplays in various fields of medicine such as chemotherapy. Here, we evaluated antioxidant and

The role of nutritional impairment in carbon-water balance of silver fir drought-induced dieback. [PDF]

Glob Chang Biol, 2022
Declining silver fir trees show lower foliar concentrations of essential nutrients such as P, K, Cu and Ni than non‐declining trees. This nutritional impairment exacerbates and amplifies the negative effects of drought on tree functioning and growth, considering the relationship of tree nutritional status with water‐use efficiency and growth resilience

Estadios Isotópicos Marinos. Estratigrafía de los isótopos del oxígeno

Cuaternario y Geomorfología, 2022
La estratigrafía de los isótopos del oxígeno no es un método de datación por sí mismo, sino que es necesaria la comparación de nuestros registros con secuencias isotópicas “globales “para su correlación.

Diferentes modos de vida, diferentes dietas. Caries e isótopos estables en dos poblaciones burgalesas medievales

Munibe Antropologia - Arkeologia, 2022
Se comparan dos poblaciones burgalesas medievales con cementerios excavados en roca: Palacios de la Sierra (siglos IX-XIII), núcleo con economía basada principalmente en ganadería y explotación maderera en un entorno frío y montañoso, y Santa María de ...
