Robust Peak Detection Techniques for Harmonic FMCW Radar Systems: Algorithmic Comparison and FPGA Feasibility Under Phase Noise

Signals
Accurate peak detection in the frequency domain is fundamental to reliable range estimation in Frequency-Modulated Continuous-Wave (FMCW) radar systems, particularly in challenging conditions characterized by a low signal-to-noise ratio (SNR) and phase ...

Validating gut flushing as a non‐lethal sampling technique for diet monitoring in agastric fish

Journal of Fish Biology, Volume 108, Issue 4, Page 1192-1199, April 2026.
Abstract Non‐lethal diet sampling is essential where individual‐level monitoring and welfare matter, yet evidence on season‐long outcomes in agastric fishes is scarce. We tested syringe‐based gut flushing in pond‐reared common carp Cyprinus carpio over one growing season (April–September) using PIT‐tagged fish assigned a priori to three handling ...

A Passive Rfid Transponder Using Harmonic Generation Of Nonlinear Transmission Lines [PDF]

, 2012
In conventional passive RFID systems, the reader (interrogator) transmits signals to serve not only as an interrogation signal, but also as a power source to the tag (transponder).

Selection Against Hybrids Maintains Genetic Divergence Between Populations of a Coastal Cleaner Fish Translocated Across a Genetic Break

Evolutionary Applications, Volume 19, Issue 3, March 2026.
ABSTRACT Genetic divergence between populations and/or species is mainly driven by reproductive isolation, that is, reduced gene flow, due to either pre‐ and/or postzygotic barriers. In this study, we investigate the role of (i) reproductive ecological interactions and (ii) mechanisms of evolutionary isolation between two genetically differentiated ...

Locating nests of endangered bumble bees: Lessons from field trials in northern Germany

Insect Conservation and Diversity, Volume 19, Issue 2, Page 268-279, March 2026.
Tracking bumble bees to find their nests using coloured strips of paper stuck to their thorax proved to be the most suitable method, while radio transponders were too heavy. Tracking times of up to 2 h and distances of up to 800 m were achieved with strips of pink craft tissue paper.

A blacktip's black tip: The reliability of using dorsal‐fin patterns for photo identification of blacktip reef sharks (Carcharhinus melanopterus)

Journal of Fish Biology, Volume 107, Issue 4, Page 1224-1236, October 2025.
Abstract Photo identification (photo ID) has increasingly become a valuable technique serving not only to identify individual animals but also to monitor populations, track migration patterns and assess wildlife health, among others uses. Various species of sharks are amenable to photo ID, among which the blacktip reef shark (Carcharhinus melanopterus)
