Diversity and extracellular enzymatic activity of culturable yeasts isolated from soil in a Brazilian Amazonian rainforest biomeNARA Subscribed
The Amazon rainforest represents the largest and most biodiverse tropical rainforest in the world, comprising over half of the planet’s remaining rainforests. In this study, we investigated the yeast distribution in the soils in a Brazilian Amazonian rainforest biome. The collection sites included two upland forests, a black-water floodplain forest, and an Amazonian dark earth site. Yeasts were isolated using both enrichment a...
Biochar-driven shifts in the soil bacterial community structure of degraded semiarid soilsNARA Subscribed
Low biochar rates (5 Mg ha −1 ) increased bacterial richness and diversity in degraded soil. Biochar origin controlled microbial assembly and niche specialization patterns. Sewage-sludge biochar favored stress-tolerant and metal-adapted bacterial taxa. Cashew bagasse biochar enhanced nitrogen cycling and chemoheterotrophic functions. Network complexity peaked at intermediate biochar doses and declined at high rates. Biochar ha...
Main conclusion Commelina erecta L. leaf sheaths fuse postgenitally without KN1 ortholog expression, indicating a distinct molecular mechanism for sheath fusion in Commelinaceae , contrasting it from sheath formation in Poaceae . Abstract Leaf sheaths are common structures within monocotyledonous, being open or closed depending on the separation of their margins. In Commelinaceae, a family of monocotyledonous plants with simpl...
Commercial aquaculture of marine ornamental fishes disproportionately targets demersal spawners with simple husbandry requirementsNARA Subscribed
Marine aquaculture currently supplies over half of the fish consumed worldwide, mostly involving pelagic spawners. In contrast, marine ornamental fish aquaculture appears to rely more on demersal spawners, which may offer management advantages, such as parental care, larger eggs and larger larvae at hatching. We assessed whether ornamental fish aquaculture is biased towards species with simpler husbandry practices. Six reprodu...
Interpretable deep learning reveals spatiotemporal MRI features of brain aging that align with neurodegenerationNARA Subscribed
Cortical thinning and atrophy are hallmarks of brain aging that have been characterized using magnetic resonance imaging (MRI). Brain aging involves many neuroanatomic features whose effects on brain structure remain unexplored. To address this challenge, we trained interpretable deep neural networks (DNNs) to estimate brain age (BA) from T 1 -weighted ( T 1 w) MRI. By identifying MRI features unapparent to humans, DNNs can fi...
Distributed optical fibre sensing (DOFS) is a technology that enables continuous, real-time measurements of a range of environmental parameters along the length of a fibre optic cable. In this article, we review the recently emerged applications of DOFS techniques in physical oceanography and offer a perspective on the technology's potential for future growth within the field. The introduction of DOFS to physical oceanography...
Extreme Droughts Push Heterotrophic Functions Above Baseline Levels in a Neotropical EcosystemNARA Subscribed
Droughts are intensifying in the humid Neotropics, raising concerns about the impacts on ecosystem processes related to C cycling, such as decomposition and CO 2 respiration. In particular, the resilience of multiple functions to extreme droughts in Neotropical aquatic systems remains poorly understood, limiting our ability to predict drought‐driven feedbacks on C cycling. Here, we used rain shelters placed above tank bromelia...
In 2023, more than half of olive harvests ( Olea europaea ) across Spain, Greece, and Türkiye were lost to drought. The same year late freeze destroyed 90% of the peach crop ( Prunus persica ) on the Georgia Piedmont and the apple crop ( Malus domestica ) in central New York, Vermont, and southern Quebec. Climate extremes now rank with the costliest threats to agriculture, but their role in forest recovery from diebacks that a...
Alcohol and tobacco use among sexual and gender minority cancer survivors in relation to urbanicity/ruralityNARA Subscribed
Purpose Understanding how place of residence affects cancer-related health risks is paramount to addressing health disparities in sexual and gender minority (SGM) cancer survivors. This study examined the associations between urbanicity and other social drivers of health on current tobacco and alcohol use in SGM cancer survivors. Methods The OUT: National Cancer Survey Study was a cross-sectional, online survey created by the...
Museomics Sheds Light on Evolutionary Diversity in a Critically Endangered Cockatoo Species From WallaceaNARA Subscribed
Accurate identification of evolutionarily significant units of rare and threatened organisms provides a foundation for effective management and conservation. Up to seven subspecies of the critically endangered Yellow‐crested Cockatoo ( Cacatua sulphurea ) have been described, four of which were commonly recognised pre‐2014. In the absence of genotypic data, C. sulphurea subspecies delimitation has been based on morphology, beh...
An ichthyological borderland: The fishfauna of Nyungwe National Park and surroundings (Rwanda, East Africa)NARA Subscribed
Nyungwe National Park (NP) is a mountainous region situated in the southwestern part of Rwanda on Congo‐Nile watershed. In spite of the high biodiversity in primates, birds and plants, no fish were reported to occur in the park, probably because of the cold temperatures of the rivers. An expedition in 2022 examined the fish diversity within the Nyungwe NP and its buffer zones. Additional sampling was performed in the main rive...
SpiderATLAS : A Database of Spider Traits and Distributions in the Brazilian Atlantic ForestNARA Subscribed
Aim Biodiversity shortfalls related to limited knowledge about geographic distribution (Wallacean) and species traits (Raunkiæran) are extremely common in many animal groups and perhaps more evident in invertebrate groups such as spiders. This lack of knowledge could present challenges for researchers investigating the response and effects of spiders along large spatial scales, particularly in the Global South. The aim of the...
