"La publicación de la teoría de Charles Darwin supuso un antes y un después en el estudio de la vida en nuestro planeta. ¿De dónde venimos?, ¿cómo hemos llegado hasta aquí? Sin embargo, este tipo de preguntas no ...

The conquest of the terrestrial environment required numerous adaptations, although aerial respiration was what allowed animals to become completely independent of aquatic environments. Here, we analyze the specialized o...

Anthropogenic climate change is one of the main threats to global biodiversity, with amphibians being among the most vulnerable vertebrate groups. In this context, the IUCN currently lists 69 species of Neotropical glass...

Western corn rootworm (Diabrotica virgifera) (WCR) depends on the continuous availability of corn. Broad adoption of annual crop rotation between corn (Zea mays) and nonhost soybean (Glycine max) exploited WCR biology to...

Hibernation and daily torpor are two distinct forms of torpor, and although they are related, it is not known how and in which sequence they evolved. As the pattern of torpor expressed by the oldest marsupial order the o...

Abstract Background Poly(A) tails play crucial roles in regulating mRNA degradation and translation, yet their evolutionary dynamics remain largely unexplored. Results Here, we generate a comprehensive full-length RNA at...

Abstract Biological production of adipic acid, a crucial building block in nylon and polymer manufacturing, from renewable feedstocks has attracted attention as a sustainable alternative to the traditional petrochemical ...

ABSTRACT Although the issue of temporality has mainly been studied from Physics, this topic also exhibits diverse interesting aspects that could be addressed from a biological perspective. One possible way of approaching...

Abstract Selenoproteins incorporate the rare selenium-containing amino acid selenocysteine (Sec) and play crucial roles for redox homeostasis, stress response, and hormone regulation. Sec is inserted by co-translational ...

Animal promoters initiate transcription either at precise positions (narrow promoters) or dispersed regions (broad promoters), a distinction referred to as promoter shape. Although highly conserved, the functional proper...

Background - Plants in over one hundred families in habitats worldwide bear extrafloral nectaries (EFNs). EFNs display a remarkable diversity of evolutionary origins, as well as diverse morphology and location on the pla...

Abstract Background Comparative genomics and plastome phylogenomics have advanced significantly in recent years, highlighting the diversity, possible admixture, and non-neutral evolution of the predominantly considered n...

Abstract The unambiguous identification of individual chromosomes is fundamental to studying genome organisation and evolution. Sheepgrass (Leymus chinensis (Trin.) Tzvel), a perennial tetraploid grass closely related to...

Abstract The first truly terrestrial apex predators were carnivorous synapsids, which emerged in the Permian over 260 million years ago and evolved against a backdrop of harsh ecological change. In many ways, these preda...

Educators in the life sciences can be challenged by students who disagree with Darwin’s theory of evolution. This article analyses the history of Creationist’s attempts to introduce alternative explanations to Darwin...

The extended evolutionary synthesis (EES) emphasizes integrative approaches to understanding distributed adaptability, incorporating development and intergenerational effects, inclusive inheritance and niche construction...

Abstract Background Optimization of biotechnological processes is traditionally limited by time-consuming trial-and-error approaches and the complexity of simultaneously optimizing multiple, often conflicting objectives....

Dr. Carla Riva-Rossi has over 25 years’ experience studying the evolutionary ecology of anadromous fishes. She received an MS in biological sciences from the Facultad de Ciencias Naturales, Universidad Nacional de la P...

Abstract The social behaviors of microbes provide unique opportunities for testing social evolution theories. How can altruistic behaviors arise by natural selection is a central challenge in biology. Green-beard effect ...

Over more than six decades of dedicated research, Chang Meemann’s career has spanned a critical era marked by a paradigm shift in vertebrate evolution studies. Beginning in the 1950s, inspired by the pioneering ichthyo...
