Monstruos de una razón despierta. La influencia del relato bíblico en el desarrollo de las teorías científicas sobre el origen del hombre y sus variaciones

Culture & History Digital Journal, 2017
El triunfo de la razón como única forma de conocimiento natural fue sin duda el resultado más notable del cambio de paradigma que se produjo a lo largo de la llamada Revolución Científica que, desde el Renacimiento hasta la Ilustración, fue favoreciendo ...

Temperature Conditions in Artificial Sea Turtle Nests: Toward Optimized Hatchery Management

Ecology and Evolution, Volume 15, Issue 7, July 2025.
This study examined how environmental and management factors, such as wall distance and egg numbers, influence nest temperatures of Olive Ridley sea turtles in a hatchery on the Pacific coast of Guatemala. ABSTRACT Climate change poses a significant threat to species with temperature‐dependent sex determination, such as sea turtles.

The interplay between virus infection and water‐related stress is mediated by the plant metabolism of ascorbic acid

New Phytologist, Volume 247, Issue 1, Page 265-280, July 2025.
Summary Plants are often subjected to environmental variations in the context of infection such that virus‐induced and abiotic stresses co‐occur. One such environmental variation is water stress, which strongly impacts plant fitness. Although there is ample evidence of the beneficial effects of plant viruses under drought, the consequences of infection

Mutational load and adaptive variation are shaped by climate and species range dynamics in Vitis arizonica

New Phytologist, Volume 247, Issue 2, Page 998-1014, July 2025.
Summary Genetic load can reduce fitness and hinder adaptation. While its genetic underpinnings are well established, the influence of environmental variation on genetic load is less well characterized, as is the relationship between genetic load and putatively adaptive genetic variation.

Niveles y clases de variación morfológica y molecular: implicancias para el poblamiento americano [PDF]

, 2011
Las publicaciones de los últimos años en torno a la dinámica de la dispersión de nuestra especie en el continente Americano han defendido modelos de poblamiento basados en evidencias independientes (moleculares, morfológicas, arqueológicas) y han ...

Thermal tolerance is linked to anatomical but not morphological leaf traits in woody species of Andean tropical montane forests

Functional Ecology, Volume 39, Issue 6, Page 1537-1549, June 2025.
Read the free Plain Language Summary for this article on the Journal blog. Abstract The world is experiencing a rise in global temperatures as a result of climate change. Higher temperatures along with more frequent heat waves negatively impact physiological levels and ultimately lead to plant death.

Pyraloid Moth Assemblages Exhibit Complex Morphological Patterns Across an Ecuadorian Mountainous Forest

Biotropica, Volume 57, Issue 3, May 2025.
In this study, we examined how morphological traits and species diversity of Pyraloidea moths vary with temperature and vegetation cover along an Andean rainforest gradient in Ecuador. Using 4161 individuals (212 species) and cross‐validating with a larger dataset of 10,337 individuals (749 morpho‐species), we found a near‐linear decrease in diversity ...

Functional intraspecific variation in the base water potential for seed germination along soil microclimatic gradients

Functional Ecology, Volume 39, Issue 3, Page 897-911, March 2025.
Abstract The ability of plants to successfully regenerate depends on complex physiological and ecological processes, and one of the first vital stages is seed germination, which depends on temperature, light and water availability. Within species variation in seed germination allows differential responses when facing stimuli and is key for adaptation ...
