Introduction Monitoring trends in wildlife populations and their response to pressures is integral but challenging for conservation managers. Wuthuga (dugongs (Dugong dugon)) are increasingly vulnerable as extreme climatic events, such as marine heatwaves and flooding, intensify with a warming climate and increasingly impact the seagrass they are dependent upon. Methods This study estimated wuthuga abundance using two methodol...

Estimating chlorophyll-a (Chl-a) concentrations from satellite ocean color data remains challenging in the Arctic, where freshwater inputs, colored dissolved organic matter (CDOM), suspended particles, and low sun elevation alter optical properties and influence blue–green reflectance. Here, we combine satellite and in situ observations to examine how freshwater-driven optical variability shapes satellite-derived Chl-a across...

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 full extent of the ecological threat posed by non-native invasive leguminous N-fixing trees to Italian ecosystems has not been thoroughly documented at the national level. This study, conducted by the Working Group on Alien Species of the Italian Botanical Society, aims to develop a comprehensive dataset that provides information on invaded and non-invaded areas, supporting multi-scale ecological analyses on the impact of...

Various underwater survey methods have been used for coral reef assessment and long-term monitoring; however, comparing data across different methods remains challenging and can obscure ecological patterns. This study compared and aligned three commonly used survey methods in Indonesia, including line-intercept transects (LIT) and point-intercept transects (PIT) recorded on dive slates, and underwater photo transects (UPT), to...

Semi-synthetic [FeFe] hydrogenases hold exciting potential as tuneable artificial metalloenzymes for efficient hydrogen conversion (H 2 $$\rightleftharpoons$$ 2 H + + 2e − ). This work investigates the role of the bridgehead ligand in the [FeFe] hydrogenase active site through the study of two bridgehead-modified active-site variants (2-oxapropane 1,3-dithiolate, ODT, and propane 1,3-dithiolate, PDT). Replacing the native 2-az...

While an immense number of natural products have been screened for bioactivity using a variety of phenotypic assays, elucidation of their protein targets remains a significant bottleneck limiting further clinical research. Next to conventional pulldown assays and modern developments, such as cellular thermal shift assays (CETSA), yeast three-hybrid (Y3H) has emerged as a powerful yet underutilized tool that provides a low-barr...

Introduction Toxicologists may use high dose n-acetylcysteine (HD-NAC) for early-treated high-risk acetaminophen ingestions (EHRAI) given concerns over standard NAC (S-NAC) dosing’s efficacy. We utilize the novel, clinically relevant outcome of mean additional 16-hour NAC maintenance infusions (NMI) to evaluate differences in treatment duration for EHRAI patients treated with S-NAC versus HD-NAC. Methods Retrospective multista...

Mass mortality events (MMEs) are decimating populations and compromising key ecosystem functions around the globe. One taxon particularly vulnerable to MMEs is freshwater bivalve mollusks. This group has important ecosystem engineering capacities and includes highly threatened and highly invasive taxa. Thus, MMEs of freshwater bivalves have important implications for conservation and ecosystems. Despite this, little is known a...

Lifestyle-related factors may affect cognition and increase the risk of developing dementia. However, the neurobiological mechanisms underlying the effect of lifestyle-related factors on the brain are not yet fully understood. Myelin, a vital element of brain health, has previously been shown to be involved in dementia-related cognitive decline. However, whether it plays a role in the relation between lifestyle-related factors...
