Continental slopes, particularly the pockmark and salt diapir regions of the Santos Basin, represent extreme environments characterized by high hydrostatic pressure, low temperatures, elevated salinity, and limited organic matter, fostering unique bacterial communities. This study aimed to elucidate the metabolic strategies enabling survival in these conditions by exploring the genome of a Chromohalobacter israelensis strain i...

Rapid warming across Antarctica is reshaping terrestrial ecosystems, yet the dynamics of macroscopic fungi in this region remain largely undocumented. Here, we present the first ecological and statistical assessment of Agaricales fungi on Byers Peninsula, Livingston Island (South Shetland Islands, Antarctica), based on surveys conducted in February 2023. Across 20 sites, we recorded 2,566 basidiomes representing eight morphosp...

Marinobufagin (MBG), a cardiotonic steroid from Rhinella toads, exhibits potent antitumor activity. However, their involvement in the mammalian neurotoxicity remains unclear. Therefore, this study evaluated the systemic (neuro)toxicological action of MBG to understand its central effects, particularly those associated with seizure-inducing activity. Initially, physicochemical, pharmacokinetic, and drug-likeness profiles and mo...

Accurate detection of high-risk human papillomavirus (HPV) is central to cervical cancer screening. Current diagnostic strategies increasingly prioritize broad-spectrum assays to maximize genotype coverage. However, theoretical genotype breadth does not necessarily translate into effective sample-level detection when clinically dominant targets are present at low copy number. Here, we evaluated this analytical trade-off using...

Earth's biodiversity is central to ecosystem health and resilience, providing essential functions and services. The Red Sea is a recognised marine biodiversity hotspot with high endemism and unique environmental conditions that support extensive but poorly resolved biodiversity. Here, we applied metagenomic analyses to sediment samples collected from coastal to deep‐sea environments during the Red Sea Decade Expedition 2022 to...

Aim We investigate the distribution of dispersal modes — endozoochory (via animal ingestion), synzoochory (via animal seed accumulation) and anemochory (via wind)—and seed mass of woody plants across Brazilian ecosystems, testing whether their relative abundance in local plant communities could be predicted by climate, edaphic factors and dispersal agents (e.g., the main vectors moving seeds). We expected climate to be the mai...

The epidemiology of sporotrichosis, a neglected mycosis caused by Sporothrix species, has shifted in South America from classic sapronosis to urban zoonosis driven by feline transmission of the hypervirulent Sporothrix brasiliensis . However, the fine-scale transmission dynamics of this epidemic, particularly within households, remain poorly understood. Here, we dissect an intrafamilial outbreak in Brazil involving a cat (the...

Remote Sensing enables the acquisition of planting information through the spatial resolution of multispectral images obtained from Remotely Piloted Aircraft (RPA) in situ. This study aimed to evaluate the application of agricultural gypsum in citrus orchards using precision agriculture tools and image-based analysis. Multispectral images were acquired at three flight altitudes (80, 100, and 120 m) to assess their influence on...
