Chronic kidney disease is an increasing global public health concern, and the Developmental Origins of Health and Disease (DOHaD) concept proposes that adverse conditions during critical developmental windows predispose offspring to chronic disorders later in life. Maternal protein restriction (MPR), a well-established experimental model reflecting food insecurity, has been shown to impair nephrogenesis and promote long-term r...
Motivation The database initiated by the Mountain Invasion Research Network (MIREN) is one of the few globally implemented standardized vegetation surveys in mountains. The focus is on collecting plant species occurrences at 5‐year intervals along and adjacent to mountain roads spanning elevational gradients, with the goal of providing critical information about the ongoing spread of non‐native plants and the potential impacts...
Stonebrood in Argentinian wild bees: A neglected disease?NARA Subscribed
Review and future outlook for the removal of microplastics by physical, biological and chemical methods in water bodies and wastewatersNARA Subscribed
Microplastics (MPs) have become a major global environmental problem due to their accelerated distribution throughout different environments. Their widespread presence is a potential threat to the ecosystems because they alter the natural interaction among their constituent elements. MPs are considered as emergent pollutants due to the huge amount existing in the environment and by the toxic effects they can cause in living be...
Evaluating deep learning techniques for optimal neurons counting and characterization in complex neuronal culturesNARA Subscribed
The counting and characterization of neurons in primary cultures have long been areas of significant scientific interest due to their multifaceted applications, ranging from neuronal viability assessment to the study of neuronal development. Traditional methods, often relying on fluorescence or colorimetric staining and manual segmentation, are time consuming, labor intensive, and prone to error, raising the need for the devel...
The Punta Coles Natural Reserve (PCNR), located on the southern coast of the province of Ilo, Moquegua Region, Peru, houses an area rich in marine biodiversity which is composed of natural banks of benthic invertebrates, which constitute the potential and dynamic fishery of commercial interest for artisanal fishermen that impact the area. To mitigate this impact, all stakeholders need to know, understand, value, and balance th...
Admixture With Cultivated Sunflower Likely Facilitated Establishment and Spread of Wild Sunflower ( Helianthus annuus ) in ArgentinaNARA Subscribed
A better understanding of the genetic and ecological factors underlying successful invasions is critical to mitigate the negative impacts of invasive species. Here, we study the invasion history of Helianthus annuus populations from Argentina, with particular emphasis on the role of post‐introduction admixture with cultivated sunflower (also H. annuus ) and climate adaptation driven by large haploblocks. We conducted genotypin...
Dominance and rarity in tree communities across the globe: Patterns, predictors and threatsNARA Subscribed
Aim Ecological and anthropogenic factors shift the abundances of dominant and rare tree species within local forest communities, thus affecting species composition and ecosystem functioning. To inform forest and conservation management it is important to understand the drivers of dominance and rarity in local tree communities. We answer the following research questions: (1) What are the patterns of dominance and rarity in tree...
Coastal seas, shelf seas and marginal ice zones are dominated by small-scale ocean surface dynamic processes that play a vital role in the transport and exchange of climate-relevant properties such as carbon, heat, water and nutrients between land, ocean, ice and atmosphere. Mounting evidence indicates that ocean scales below 10 km have far-ranging impacts on air–sea interactions, lateral ocean dispersion, vertical stratificat...
Pollen, particularly from the Ambrosia genus, plays a pivotal role in triggering allergic rhinoconjunctivitis symptoms. This review delves into the global background of Ambrosia , focusing on its origins, invasive potential, and spread to South America. The ecological niche for Ambrosia species is explored, emphasizing its stability globally but exhibiting unique and dynamic features in South America. Information on Ambrosia p...
