Epigenetic Age Estimation for Hawaiian False Killer Whales (Pseudorca crassidens) in the Absence of ‘Known‐Age’ Individuals

open access: yesMolecular Ecology Resources, Volume 26, Issue 2, February 2026.
ABSTRACT Epigenetic aging models hold great promise for enhancing many aspects of wildlife research and management. However, their utility is limited by the need to train models using known‐aged animals, which are rare among wildlife species. We present a novel approach to developing methylation‐based age prediction models that enables us to train ...

Pollination and plant reproduction in the Cerrado, the world's most biodiverse savanna

open access: yesBiological Reviews, Volume 101, Issue 1, Page 74-105, February 2026.
ABSTRACT The Brazilian Cerrado is a continental‐wide biodiversity hotspot and the most species‐rich savanna ecosystem in the world. The main aspect characterising this biodiversity is that the landscape is arranged as an intricate mosaic of different plant formations, including grasslands, savannas, and forests, each harbouring distinct but ...

Overview of lightning location systems

Science & Technology Development Journal - Engineering and Technology, 2021
Lightning location systems provide valuable and vital data for study of lightning on the earth. Developed nations already built not only one but aslo many lightning location networks in their territories in order to collect highly reliable national dataset of lightning.

Lightning Sferics for Lightning Location – Complex Analysis

2021
<p>Lightning location networks commonly use the time stamps of the received radio waveforms from lightning flashes (sferics) at numerous stations to determine a single lightning flash location. In order to extract more information from the recorded lightning waveforms, a complex analysis of the received electromagnetic waves is ...

Performance of lightning locating systems in extracting lightning flash characteristics

Journal of Atmospheric and Solar-Terrestrial Physics, 2014
Abstract A study was carried out to compare the negative cloud to ground lightning discharges recorded using Swedish lightning locating system against time correlated direct field measurements. Only the first 200 ms time window was investigated. A total of 167 flashes were recorded and time matched against the lightning locating system records.

VHF Technique for Locating Lightning

Radio Science, 1969
The principles of a lightning location method using the VHF signals emitted by the discharge are outlined. Consideration of the source characteristics (notably signal strength and intervals between pulses; of the noise background; of the differences between the signals incident at spatially separated receivers; and of the electronic equipment now ...

Waveform and location analyses of localised lightning locating system

2010 International Conference on High Voltage Engineering and Application, 2010
Lightning mapping or locating systems are based on several working principles such as the Time of Arrival (ToA) and the Directional Finder (DF). The country wide lightning locating system (LLS) owned by TNB Malaysia is able to determine the coordinate of the cloud-to-ground lightning strike within 500m accuracy.

Lightning characteristics on Java island, observed by lightning location network

11th International Symposium on High-Voltage Engineering (ISH 99), 1999
To investigate characteristics of lightning in the tropics, an observation using a lightning detection network has been carried out on the Java Island (Indonesia) since February 1994, employing the combination of MDF and TOA techniques with four stations.
