A strong Community of Practice (CoP) can be powerful in supporting people to share, generate, and disseminate knowledge. This study evaluates the use of the Communities of Practice (CoP) approach for effective knowledge consolidation in the field of citizen science. Our paper offers an analysis of four CoPs that were set up as part of the European-based 3-year WeObserve project, with distinct themes of (1) co-design & citizen...
Tree Biomass Sensitivity to Ozone Exposure: Insights From a Decade of Free‐Air ExperimentsNARA Subscribed
Tropospheric ozone (O 3 ) is a pervasive stressor that impairs forest biomass and alters carbon allocation strategies. This study assessed biomass responses across 17 woody taxa under free‐air controlled exposure (FACE), integrating a decade of experiments conducted with an analogous exposure regime applied to deciduous and evergreen species. The analysis provided a comparative evaluation of existing flux‐based metrics. Statis...
Influence of Ketogenic Diet Lipid Composition on Anxiety-Like Behavior and Neurometabolic Profile in Healthy RatsNARA Subscribed
Ketogenic diets (KDs) modulate brain function, but how their fatty acid composition impacts behavior remains poorly understood. Male Wistar rats were fed a control diet (CD, n = 6), a classic ketogenic diet (CKD, n = 6) rich in saturated fatty acids (SAFAs), or a modified ketogenic diet (MKD, n = 6) enriched with polyunsaturated fatty acids (PUFAs) and DHA. After 100 days, both KDs induced similar ketosis and increased brain g...
The biggest landslide event in Brazil: preliminary analysis of the Rio Grande do Sul mega disaster in May 2024NARA Subscribed
An unprecedented precipitation event in Rio Grande do Sul, Brazil, between April and May 2024 caused widespread floods and landslides. This extreme event impacted 96% of the state’s municipalities, affecting approximately 2.4 million people and resulting in 183 deaths. This article reports the magnitude of this extreme event, focusing on the preliminary results of a comprehensive landslide inventory. Our analysis revealed that...
Biological approaches to mitigate heavy metal pollution from battery production effluents: advances, challenges, and perspectivesNARA Subscribed
Battery production generates effluents containing various pollutants, predominantly heavy metals such as lead (Pb), cadmium (Cd), nickel (Ni), copper (Cu), zinc (Zn), and chromium (Cr), which represent a serious risk to human health and the environment. Given their persistence, toxicity, and mobility in ecosystems and biota, heavy metals can bioaccumulate and, in some cases, enter the food chain. With this context in mind, thi...
Camera trap surveys of A tlantic F orest mammals: A data set for analyses considering imperfect detection (2004–2020)NARA Subscribed
Camera traps became the main observational method of a myriad of species over large areas. Data sets from camera traps can be used to describe the patterns and monitor the occupancy, abundance, and richness of wildlife, essential information for conservation in times of rapid climate and land‐cover changes. Habitat loss and poaching are responsible for historical population losses of mammals in the Atlantic Forest biodiversity...
The aim of this work was to evaluate the anti-inflammatory and antioxidant effects of ethyl acetate extract obtained from the leaves of Brazilian peppertree Schinus terebinthifolius Raddi (EAELSt). Total phenols and flavonoids, chemical constituents, in vitro antioxidant activity (DPPH and lipoperoxidation assays), and cytotoxicity in L929 fibroblasts were determined. In vivo anti-inflammatory and antioxidant properties were e...
Mammalian carnivores are considered a key group in maintaining ecological health and can indicate potential ecological integrity in landscapes where they occur. Carnivores also hold high conservation value and their habitat requirements can guide management and conservation plans. The order Carnivora has 84 species from 8 families in the Neotropical region: Canidae; Felidae; Mephitidae; Mustelidae; Otariidae; Phocidae; Procyon...
NEOTROPICAL ALIEN MAMMALS: a data set of occurrence and abundance of alien mammals in the NeotropicsNARA Subscribed
Biological invasion is one of the main threats to native biodiversity. For a species to become invasive, it must be voluntarily or involuntarily introduced by humans into a nonnative habitat. Mammals were among first taxa to be introduced worldwide for game, meat, and labor, yet the number of species introduced in the Neotropics remains unknown. In this data set, we make available occurrence and abundance data on mammal specie...
ATLANTIC EPIPHYTES : a data set of vascular and non‐vascular epiphyte plants and lichens from the Atlantic ForestNARA Subscribed
Epiphytes are hyper‐diverse and one of the frequently undervalued life forms in plant surveys and biodiversity inventories. Epiphytes of the Atlantic Forest, one of the most endangered ecosystems in the world, have high endemism and radiated recently in the Pliocene. We aimed to (1) compile an extensive Atlantic Forest data set on vascular, non‐vascular plants (including hemiepiphytes), and lichen epiphyte species occurrence a...
