How changes in river geometry impact flood hazard in BrazilNARA Subscribed
Discovery of a novel emaravirus and an alphacytorhabdovirus infecting Spiraea in the USANARA Subscribed
Spiraea plants showing symptoms of virus infection were investigated using high-throughput sequencing which resulted in the identification of two novel viruses: an emaravirus named Spiraea chlorotic leaf spot distortion virus (SCLSDV), and an alphacytorhabdovirus named Spiraea alphacytorhabdovirus 1 (SpCRV-1). The complete genome of SCLSDV comprises four RNA segments, each encoding a distinct protein: RNA-dependent RNA polymer...
Inactivation of Avian Influenza Virus in Raw Milk KefirNARA Subscribed
Both highly pathogenic avian influenza virus (HPAIV) and its viral RNA have been detected in raw milk during the ongoing outbreak in dairy cows. While pasteurization effectively inactivates the virus in milk, comparatively little has been published on AIV inactivation in fermented dairy products made from raw milk. We evaluated the viability of two isolates of low pathogenic avian influenza virus (LPAIV) during fermentation of...
Tropical Montane Cloud Forests Have High Resilience to Five Years of Severe Soil DroughtNARA Subscribed
Tropical montane cloud forests (TMCFs) are globally important ecosystems, acting as large carbon sinks and supporting exceptional biodiversity. However, climate‐driven declines in rainfall threaten these forests, but their responses to long‐term soil moisture deficit remain poorly understood. We implemented a 5‐year throughfall exclusion (TFE) experiment in a Peruvian TMCF, reducing soil moisture by 69.1% across a 0.09 ha plot...
Lettuce Growth Under Desalinated Seawater Irrigation: Effects on Yield, Nutrient Uptake, and Soil PropertiesNARA Subscribed
The use of non-conventional water sources, such as desalinated seawater (DSW), for agricultural irrigation is increasing in arid and semi-arid regions, raising concerns about potential impacts on crop physiology, productivity, and soil health. This study assessed the agronomic effects of DSW irrigation on iceberg lettuce ( Lactuca sativa var. capitata ) grown over four consecutive seasons in outdoor pallet boxes. Three water q...
The Mongolian Gerbil ( Meriones unguiculatus ) diverged from rats/mice around 45 million years ago and developed adaptations to extreme temperatures and water scarcity. Another feature of the Mongolian Gerbils is their social monogamy similar to that of prairie voles. These observations suggest that there are potential differences in the Mongolian Gerbil brain that are distinct from that of rats and mice. The goal of the prese...
Speciation is rarely observable directly. A way forward is to compare pairs of ecotypes that evolved in parallel in similar contexts but have reached different degrees of reproductive isolation. Such comparisons are possible in the marine snail Littorina saxatilis by contrasting barriers to gene flow between parallel ecotypes in Spain and Sweden. In both countries, divergent ecotypes have evolved to withstand either crab preda...
Native Australian seedlings exhibit novel strategies to acclimate to repeated heatwave eventsNARA Subscribed
Heatwaves are becoming more intense and frequent. Plant photosystem thermal thresholds can vary with species, but also shift in response to environmental triggers. Both upper and lower thresholds can acclimate to repeated heatwaves through ecological stress memory, where prior exposure primes them for subsequent events. The extent to which acclimation to repeated heat stress events varies among environmental origin and/or spec...
Chemotherapy-Induced Cell-Surface GRP78 Expression as a Prognostic Marker for Invasiveness of Metastatic Triple-Negative Breast CancerNARA Subscribed
Metastasis remains the leading cause (90%) of cancer-related mortality, especially in metastatic triple-negative breast cancer (TNBC). Improved understanding of molecular drivers in the metastatic cascade is crucial, to find accurate prognostic markers for invasiveness after chemotherapy treatment. Current breast cancer chemotherapy treatments include doxorubicin and paclitaxel, inducing various effects, such as the unfolded p...
Specific myogenic microRNAs termed “myomiRNAs” are involved in skeletal muscle development and regeneration, and an obesogenic environment in utero may affect these processes. The present study aimed to determine whether this environment induced variations in the expression levels of myomiRs-31, −133, −136, −206, and −296 and whether the administration of (-)-epicatechin (Epi), an exercise mimetic, could modify these variation...
High resistance to non-native plant invasion exhibited in a maritime alpine environmentNARA Subscribed
Most alpine ecosystems are subject to non-native species invasion as climate warms and human disturbance increases. Therefore, it is important to identify the main barriers and facilitators of alpine plant invasions. While there is much research in continental alpine areas, there is limited research in maritime environments, which have distinctive biological, edaphic and geomorphologic features due to the scarcity of snow in w...
