Ecological divergence in movement and habitat use of long-finned pilot whales (Globicephala melas) across the subpolar North AtlanticNARA Subscribed
Despite their widespread presence across the North Atlantic, it remains unclear how long-finned pilot whales ( Globicephala melas ) differ regionally in their movement patterns and habitat use, and what this means for population structure. Satellite transmitters attached to pilot whales in the Faroe Islands ( n = 11), East Greenland ( n = 6), and Iceland ( n = 2) between 2023 and 2025 revealed consistent regional differences i...
Biofertilizer Foliar Application to the Vineyard: Preliminary Effects On Grape Nitrogen, Aromatic and Phenolic CompositionNARA Subscribed
This work evaluated, for the first time, the effect of the biofertilizer BlueN® foliar application on grape composition. The experiment included a control (no treatment) and BlueN® foliar application at the onset of flowering. Treatments were arranged in a completely randomized block design with three replicates. Foliar application of BlueN® significantly increased total acidity, the only general parameter of grapes that was a...
Introduction Age estimation is an important tool for understanding the life history of animal populations, and several techniques have been developed, each with its own strengths and limitations. Methods In this study, we apply a novel age estimation method that utilizes trace element signals with seasonal components obtained through laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) on tusks of 16 narwhal...
One of the last pristine marine soundscapes, the Arctic, is exposed to increasing anthropogenic activities due to climate-induced decrease in sea ice coverage. In this study, we combined movement and behavioral data from animal-borne tags in a controlled sound exposure study to describe the reactions of narwhals, Monodon monoceros , to airgun pulses and ship noise. Sixteen narwhals were live captured and instrumented with sate...
Eyeballs from 121 fin whales ( Balaenoptera physalus ) and 83 harbor porpoises ( Phocoena phocoena ) were used for age estimation using the aspartic acid racemization (AAR) technique. The racemization rate ( k A sp ) for fin whales was established from 15 fetuses (age 0) and 15 adult whales where age was estimated by reading growth layer groups (GLGs) in the earplugs. The ( k A sp ) for harbor porpoises was derived from 15 por...
