Under the current global biodiversity crisis, there is a need for automated and noninvasive monitoring techniques that can gather large amounts of data cost‐effectively at various ecological scales, from local to large spatial scales. These data can then be analyzed to inform stakeholders and decision‐makers. One such technique is passive acoustic monitoring, which is commonly coupled with automatic identification of animal sp...
Soil microbial activity is a key indicator of soil health, traditionally assessed using methods like enzymatic activity, community-level physiological profiling (CLPP), microbial biomass, and soil respiration. This study introduces isothermal microcalorimetry assessed with the CalScreener™ system as a novel tool for evaluating soil activity and validates its use in assessing the impact of anthropogenic pollutants like micropla...
Key conservation actions for European steppes in the context of the Post-2020 Global Biodiversity FrameworkNARA Subscribed
The Kunming–Montreal Global Biodiversity Framework (KM–GBF) envisions a world living in harmony with nature by 2050, with 23 intermediate targets to be achieved by 2030. However, aligning international policy and national and local implementation of effective actions can be challenging. Using steppe birds, one of the most threatened vertebrate groups in Europe, as a model system, we identified 36 conservation actions for the a...
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...
Bacterial septicemia and herpesvirus infection in Antarctic fur seals (Arctocephalus gazella) stranded in the São Paulo coast, BrazilNARA Subscribed
In August 2021, two juvenile male Antarctic fur seals ( Arctocephalus gazella ) stranded in the southeastern Brazilian coast and were referred to rehabilitation centers. The animals presented increased body temperature, prostration, respiratory distress and despite treatment died. A necropsy following a standardized protocol was performed, and formalin-fixed tissues were processed for microscopic examination. Samples were scre...
Efficacy of powdered alfalfa leaves to ameliorate the toxic effects of aflatoxin B1 in turkey poultsNARA Subscribed
This experiment was conducted to determine the effect of an adsorbent material based on powdered alfalfa leaves added in the aflatoxin B 1 (AFB 1 )-contaminated diet of turkey poults on production parameters, blood cell count, serum biochemistry, liver enzymes, and liver histology. For this purpose, three hundred and fifty female Nicholas-700 poults were randomly assigned into five treatments: (1) Control, AFB 1 -free diet; (2...
Metabolic quotient and specific enzymatic activity in response to the addition of organic amendments to mining tailingsNARA Subscribed
Adding organic amendments to mining tailings to ameliorate extreme conditions that limit plant growth is a common practice in reclamation projects; still, the impact on microbial activity is not commonly considered. This work aimed to explore the use of the metabolic quotient and specific enzymatic activity as indicators of microbial carbon use efficiency in response to adding organic amendments to mining tailings. An experime...
Aim To determine the relationships between the functional trait composition of forest communities and environmental gradients across scales and biomes and the role of species relative abundances in these relationships. Location Global. Time period Recent. Major taxa studied Trees. Methods We integrated species abundance records from worldwide forest inventories and associated functional traits (wood density, specific leaf area...
Validation of a neural network based model to predict foF2NARA Subscribed
Magnetic and elemental characterization of the particulate matter deposited on leaves of urban trees in Santiago, ChileNARA Subscribed
Airborne particulate matter is a serious threat to human health, especially in fast-growing cities. In this study, we carried out a magnetic and elemental study on tree leaves used as passive captors and urban dust from various sites in the city of Santiago, Chile, to assess the reliability of magnetic and elemental measurements to characterize particulate matter pollution from vehicular origin. We found that the magnetic susc...
