Abstract A key factor contributing to the success of Darwin and Wallace’s theory of biological evolution by natural selection was its population-level perspective. This conceptual framework was not immediately adopted,...

IntroductionThe African sugarcane stalk borer (Eldana saccharina) is a major insect pest of sugarcane in Sub-Saharan Africa. Because its larvae reside inside sugarcane stalks, conventional measures are less effective. Po...

Abstract Neural populations that are able to extract quantitative information from multiple sensory domains are essential for the survival of numerous species. How quantity is encoded across different senses is far from ...

Abstract Background Melissa officinalis (balm) is a perennial medicinal. Climate change and high cultivation costs necessitate the breeding of new cultivars with improved stress tolerance and high metabolite content. How...

ABSTRACT Proper maintenance of the cold chain is essential to ensure both food quality and safety. This laboratory activity was designed to help undergraduate students understand the microbiological implications of cold ...

Aun cuando solo quedan menos de 500 ejemplares de huemul patagonico (Hippocamelus bisulcus) en Argentina, existe escasa información sobre su ecología y dinámicas poblacionales. Por primera vez en la historia de Argent...

Macrobrachium surinamicum is an indigenous prawn distributed from the lower Amazon and Tocantins river basins to Venezuela in the Orinoco Delta region. It is common bycatch fauna of Macrobrachium amazonicum artisan fishi...

In the House Wren (Troglodytes aedon), polygyny is characterized by males' partial desertion, males providing little or no help in feeding the nestlings of one of their mates. We evaluated whether contributions to feedin...

Thermal traits knowledge is elemental to forecasting the impacts of environmental change on lizard diversity. Daily and seasonal environmental temperature fluctuations are amplified in desert and semi-desert species. As ...

ObjectivesMevalonate kinase deficiency (MKD) is a metabolic disorder caused by a block in the mevalonate pathway, leading to impaired synthesis of cholesterol and isoprenoids. Clinically, MKD presents with recurrent infl...

This data paper describes bacterial and fungal communities associated with the sponge Chondrilla nucula collected from two Eastern Mediterranean populations (North and South Aegean Sea) and maintained under controlled co...

The pandemic of severe acute respiratory syndrome coronavirus 2 (SARS2) affected the geriatric population. Among research models, Golden Syrian hamsters (GSH) are one of the most representative to study SARS2 pathogenesi...

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...

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...

Developmental plasticity, the ability to regulate aspects of development in response to environmental cues, is hypothesized to evolve in response to environmental heterogeneity and may facilitate dispersal, novel habitat...

Abstract Background Flowering time is a key phenological trait in chickpea (Cicer arietinum L.), determining adaptation to different agro-climatic conditions and directly influencing yield. Here, we investigated the gene...

The HMGA1 (High Mobility Group AT-hook 1) gene is considered a candidate locus for growth- and fatness-related traits in pigs due to its involvement in transcriptional regulation and energy metabolism and its localizatio...

Hunting and gathering remained the main mode of subsistence of humanity for hundreds of thousands of years, beginning some 1.8 million years ago, and until the Neolithic Revolution (some 10,000 years ago), when agricultu...

Effective management of natural populations depends heavily on the capacity for understanding and predicting their habitat requirements. For endemic and threatened species like the mara (Dolichotis patagonum), this infor...

Abstract. With levels of medicine and pharmacology individualization constantly increasing, the scientific community is becoming seriously concerned about the safety of existing and developing drugs for the pediatric pop...

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 ...

We present the case of a 43-year-old male who presented to pulmonology with 3 years of chronic cough and recurrent sinopulmonary infections. He was diagnosed with bronchiectasis and found to have mild thrombocytopenia an...

Abstract Cuproptosis is a recently identified copper-dependent cell death pathway with growing relevance in tumor biology, yet its involvement in thyroid carcinoma (TC) remains poorly understood. In this study, we integr...
