Chilean Blue Whales: Fidelity to Feeding Areas and Migratory Connectivity With the Eastern Tropical Pacific 1NARA Subscribed
In the Eastern South Pacific (ESP), blue whale ( Balaenoptera musculus subsp.) aggregations have been described for two feeding areas (in northern and southern Chile) and in the Eastern Tropical Pacific (ETP). However, despite the knowledge of these areas, little is known about the seasonal movements of blue whales between them. Comparisons of 1074 individual blue whales, photographed across these regions from 1992 to 2019, re...
Chlorine in plants and soils of a tropical lower montane forest in Ecuador: Development during two decadesNARA Subscribed
Aims Cl is a micronutrient mainly supplied via deposition of marine aerosols. We assessed the development of Cl concentrations and stocks in plants and soils of a tropical montane forest far from a downwind ocean during two decades (1998–2019). Methods We measured Cl concentrations in solid samples with a new combustion-based method. Results The Cl concentrations in leaves of 17 tree species ranged 0.04–1.6 g kg −1 . Three tre...
Wet Atmospheric Deposition Damage on Coral Limestone: An Assessment for Conservation PurposesNARA Subscribed
Coral limestone is an important building material worldwide. In this research, a limestone of coral origin (called múcara stone from Veracruz, Mexico) was subjected to weathering tests with the aim to develop an equation relating wet atmospheric deposition volume to stone damage. A two-year rain sampling campaign was performed in Veracruz, Mexico. The volume weighted mean (VWM) of major ions in precipitation was used to prepar...
Ri plants characteristically exhibit a compact architectural growth habit, enhancing the economic value of ornamental varieties. These plants are obtained through the natural transformation of plant cells using wild strains of Rhizobium rhizogenes , which means they are not classified as genetically modified organisms (GMOs) in some countries, as USA or Japan. In the standard transformation protocol, rol genes are transferred...
Evaluating deep learning techniques for optimal neurons counting and characterization in complex neuronal culturesNARA Subscribed
The counting and characterization of neurons in primary cultures have long been areas of significant scientific interest due to their multifaceted applications, ranging from neuronal viability assessment to the study of neuronal development. Traditional methods, often relying on fluorescence or colorimetric staining and manual segmentation, are time consuming, labor intensive, and prone to error, raising the need for the devel...
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...
