Assessing the effectiveness of foraging radius models for seabird distributions using biotelemetry and survey data (2019)

Critchley, Emma Jane; Grecian, W. J.; Bennison, Ashley; Kane, Adam; Wischnewski, Saskia; Cañadas, A.; Tierney, D.; Quinn, John L.; Jessopp, Mark J.

Abstract:

Relatively simple foraging radius models have the potential to generate predictive distributions for a large number of species rapidly, thus providing a cost‐effective alternative to large‐scale surveys or complex modelling approaches. Their effectiveness, however, remains largely untested. Here we compare foraging radius distribution models for all breeding seabirds in Ireland, to distributions of empirical data collected from tracking studies and aerial surveys. At the local/colony level, we compared foraging radius distributions to GPS tracking data from seabirds with short (Atlantic puffin Fratercula arctica, and razorbill Alca torda) and long (Manx shearwater Puffinus puffinus, and European storm‐petrel Hydrobates pelagicus) foraging ranges. At the regional/national level, we compared foraging radius distributions to extensive aerial surveys conducted over a two‐year period. Foraging radius distributions were significantly positively correlated with tracking data for all specie...

Biotelemetric Monitoring of Brain Neurochemistry in Conscious Rats Using Microsensors and Biosensors (2009)

Calia, Giammario; Rocchitta, Gaia; Migheli, Rossana; Puggioni, Giulia; Spissu, Ylenia; Bazzu, Gianfranco; Mazzarello, Vittorio; Lowry, John P.; O'Neill, Robert D.; Desole, Maria S.; Serra, Pier A.

Abstract:

In this study we present the real-time monitoring of three key brain neurochemical species in conscious rats using implantable amperometric electrodes interfaced to a biotelemetric device. The new system, derived from a previous design, was coupled with carbon-based microsensors and a platinum-based biosensor for the detection of ascorbic acid (AA), O2 and glucose in the striatum of untethered, freely-moving rats. The miniaturized device consisted of a single-supply sensor driver, a current-to-voltage converter, a microcontroller and a miniaturized data transmitter. The redox currents were digitized to digital values by means of an analog-to-digital converter integrated in a peripheral interface controller (PIC), and sent to a personal computer by means of a miniaturized AM transmitter. The electronics were calibrated and tested in vitro under different experimental conditions and exhibited high stability, low power consumption and good linear response in the nanoampere current rang...

IMPAQT Miniaturized Underwater Acoustic Telemetry Platform: Transmitter Node System Design (2020)

Jafarzadeh, Hamed; Belcastro, Marco; O'Flynn, Brendan

Abstract:

The marine environment and its natural resources are an essential part of the geographical ecosystem and a great food source for humans. In recent years, terrestrial wireless sensor networks and Internet of Things (IoT) technologies have developed rapidly; however, due to the limitation of signal propagation in water, there is less development and advancement in the underwater sensors network domain. IMPAQT is a European research project aiming at the development of the technologies and methods to promote and support inland, coastal zone and offshore Integrated Multi-Trophic Aquaculture (IMTA) sites. As part of the IMPAQT project, a novel underwater acoustic telemetry platform has been proposed and is under development, to provide a method to collect and transmit sensors data underwater. The proposed platform architecture consists of several ultrasonic transmitter sensor nodes and a gateway buoy as a data aggregator interface. Transmitter nodes will collect and log underwater sensor...

Marine Mammals and Megafauna in Irish Waters - Behaviour, Distribution and Habitat Use- Final Summary Report. (2013)

Marine Mammals and Megafauna in Irish Waters - Behaviour, Distribution and Habitat Use- Final Summary Report. (2013)

Berrow, S.D.; O’Brien, J.; O’Connor, I.; McGrath, D.; Wall, D.

Abstract:

Irish waters are internationally important for cetaceans (whales, dolphins and porpoises), with 24 species recorded to date. These range from the harbour porpoise, the smallest species in European waters, to the blue whale, the largest animal to ever have lived on Earth. All cetaceans and their habitats are protected under Irish and international law. The research termed Marine Mammals and Megafauna in Irish Waters – behaviour, distribution and habitat use was delivered under six Work Packages. The deliverables under this project will provide data which could be used to address a wide range of issues, and will contribute to developing policy advice on meeting Ireland’s statutory obligations.

Abstract:

All cetaceans and their habitats are protected under Irish and international law. The research termed Marine Mammals and Megafauna in Irish Waters – behaviour, distribution and habitat use was delivered under six Work Packages. Cetacean line transect surveys were conducted under Work Package 1 with the following goals: 1. Providing a baseline cetacean distribution and relative abundance data set for the Irish EEZ; 2. Filling spatial and temporal gaps identified in cetacean survey effort within the EEZ; 3. Preparing an Atlas of cetacean distribution and relative abundance for Irish waters; 4. Assessing the temporal use of marine habitats by cetaceans in Irish waters.

Marine Mammals and Megafauna in Irish Waters - Behaviour, Distribution and Habitat Use- WP3 Biotelemetry of Marine Megafauna in Irish Waters (2013)

Abstract:

Biotelemetry is the transmission of information from biological organisms through the atmosphere by radio waves. It encompasses a wide range of devices that can record environmental variables while attached to an animal, such as depth, salinity and temperature, while permitting the recording and transmitting of the position of an animal, commonly referred to as tracking. A review of biotelemetry, with reference to relevant species in Ireland, is presented. Although a number of marine species have been tagged and tracked in Ireland, these studies were generally of short duration or involved small numbers of individuals. However, these studies have shown that tracking marine megafauna in Ireland can be successful and that there is great potential for biotelemetry.
