Deficits in cerebral blood flow (CBF) and cerebrovascular reactivity (CVR) may indicate vulnerability to vascular dysfunction and cognitive impairment. Prior findings on age-related change in CVR are mixed, and no studies to date have investigated age group differences in spontaneous CVR (sCVR) at rest. The present study compared whole brain and regional sCVR at rest between 24 healthy younger adults (ages 18–34) and 163 cogni...
Extrafloral nectaries (EFNs) are specialized plant glands that secrete nectar but are not related to pollination. Several ants feed on EFNs and, in exchange, they often attack herbivores, reducing the consumption of leaf tissue and floral parts, and enhancing plant performance. Although most empirical studies and reviews have demonstrated that ant visitation benefits EFN‐bearing plants, many others have failed to show ants as...
Dipteran parasitoids as biocontrol agentsNARA Subscribed
Numerous studies conducted on a variety of temporal and spatial scales around the world show that dipteran parasitoids can exert effective control over some insect pests. This paper provides an overview of major examples of successful classical and augmentative biological control initiatives, organized by major dipteran families which include parasitoid species (i.e., Tachinidae, Phoridae, Sarcophagidae, Cryptochetidae, Bombyl...
Contributions of the IUCN Red List of Ecosystems to risk‐based design and management of protected and conserved areas in AfricaNARA Subscribed
Protected and conserved areas (PCAs) are key ecosystem management tools for conserving biodiversity and sustaining ecosystem services and social cobenefits. As countries adopt a 30% target for protection of land and sea under the Global Biodiversity Framework of the United Nations Convention on Biological Diversity, a critical question emerging is, which 30%? A risk‐based answer to this question is that the 30% that returns th...
NEOTROPICAL FRESHWATER FISHES : A dataset of occurrence and abundance of freshwater fishes in the NeotropicsNARA Subscribed
The Neotropical region hosts 4225 freshwater fish species, ranking first among the world's most diverse regions for freshwater fishes. Our NEOTROPICAL FRESHWATER FISHES data set is the first to produce a large‐scale Neotropical freshwater fish inventory, covering the entire Neotropical region from Mexico and the Caribbean in the north to the southern limits in Argentina, Paraguay, Chile, and Uruguay. We compiled 185,787 distri...
Fatty acids are key components in the structural diversity of lipids and play a strategic role in the functional properties of lipids which determine the integrity of neuronal and glial cell membranes, the generation of lipid signaling mediators, and the chemical reactivity of acyl chains. The present study analyzes using gas chromatography the fatty acid profiles of 13 regions of the human central nervous system in healthy in...
Combined simulation and optimization framework for irrigation scheduling in agriculture fieldsNARA Subscribed
In the context of growing evidence of climate change and the fact that agriculture uses about 70% of all the water available for irrigation in semi-arid areas, there is an increasing probability of water scarcity scenarios. Water irrigation optimization is, therefore, one of the main goals of researchers and stakeholders involved in irrigated agriculture. Irrigation scheduling is often conducted based on simple water requireme...
