Habitat-associated detection of Toxoplasma gondii and Sarcocystis spp. in Cetaceans from the Brazilian coastNARA Subscribed
Cetaceans are sentinels of marine ecosystem health and are increasingly exposed to protozoal pathogens. This study investigated the occurrence and molecular identity of Sarcocystidae protozoa in 159 stranded cetaceans representing 21 species along the Brazilian coast. Molecular analysis based on PCR amplification and sequencing of the sarcocystid internal transcribed spacer 1 (ITS1) region revealed infections in 14 individuals...
Drought modulates ozone stress through BVOCs, antioxidant defenses, and metabolic responses in a tropical treeNARA Subscribed
Main conclusion Water limitation attenuated ozone-induced oxidative stress in Eugenia uniflora, maintaining physiological stability and promoting targeted biogenic volatile organic compounds (BVOCs) and metabolic adjustments rather than large-scale disruption. Abstract Tropical forests are increasingly exposed to multiple environmental stressors, yet the combined effects of drought and ozone on native tropical tree species rem...
Fruit-mediated Autoallelopathic Effects on Seed Germination of Pilosocereus catingicola subsp. salvadorensisNARA Subscribed
Autoallelopathy refers to the inhibitory effect of plant-derived compounds on seeds or seedlings of the same species and may influence germination and early establishment. In this study, we evaluated the potential autoallelopathic effect of the funicular pulp of Pilosocereus catingicola subsp. salvadorensis on the germination of its own seeds. We collected fruits from 20 individuals belonging to Caatinga and Restinga populatio...
Biodiversity and Management as Central Players in the Network of Relationships Underlying Forest ResilienceNARA Subscribed
Global change is threatening the integrity of forest ecosystems worldwide, amplifying the need for resilience‐based management to ensure their conservation and sustain the services they provide. Yet, current efforts are still limited by the lack of implementation of clear frameworks for operationalizing resilience in decision‐making processes. To overcome this limitation, we aim to identify reliable and effective drivers of fo...
Between 2022 and 2023 ascaridoid nematodes of the genus Hexametra were recovered from two captive central bearded dragons ( Pogona vitticeps Ahl) in the Extremadura region of Spain. These nematodes were identified by an integrative approach combining morpho-anatomical and molecular data. We used two rRNA regions (D2–D3 expansion segments of the 28S, and ITS fragments), and the partial region of the cytochrome oxidase I gene (C...
ORF, an operational framework to measure resilience in social–ecological systems: the forest case studyNARA Subscribed
Resilience is commonly addressed when dealing with the sustainable planning and management of social–ecological systems, but we lack a unified framework for its quantitative assessment and application. We present an operational resilience framework (ORF) based on recognizing and relating several elements: system variables (e.g., ecosystem services), disturbances and stressors acting at given spatiotemporal scales, a reference...
In recent years, the environmental effects of both active and legacy mining activity have motivated many research groups worldwide through the use of a variety of methods that have been conducted among diverse environments. In this study, we measured radionuclide concentrations at two coastline locations of the Northern Aegean Sea: Stratoni and Ierissos. We deployed KATERINA II, an in situ gamma ray spectrometer. Our results i...
Understanding biosecurity: knowledge, attitudes and practices of seaweed farmers in the PhilippinesNARA Subscribed
Farmers are one of the most important components of any plant-based cultivation industry. The Philippines is one of the world’s major producers of red carrageenophyte algae and has tens of thousands of farmers involved in this industry. The production of algae such as Kappaphycus and Eucheuma increased significantly from the early 1970s, when the industry was established, before declining from the mid-2000s, due to a number of...
Urinary metabolic signatures reflect cardiovascular risk in the young, middle-aged, and elderly populationsNARA Subscribed
The predictive value of traditional cardiovascular risk estimators is limited, and young and elderly populations are particularly underrepresented. We aimed to investigate the urine metabolome and its association with cardiovascular risk to identify novel markers that might complement current estimators based on age. Urine samples were collected from 234 subjects categorized into three age-grouped cohorts: 30–50 years (cohort...
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...
