We assume that the sampled migratory individuals from Padre Island used in this study possess high latitude breeding distributions throughout Alaska, Canada and Greenland as supported by band recovery [31], satellite telemetry studies [12], [32], [33] and genetics (this study; see below), and therefore represent the northern peregrine falcon breeding population in North America.
Mud pulse telemetry [1] is one of feasible wireless methods used for oil drilling operations, mainly for the control and transmission of the data from a well bottom to the surface during drilling operations.
Data were obtained using either tethers (n=10) or telemetry (n=4).
Flights were monitored in real-time via visual observers and a radio telemetry (2.4 GHz) link from a laptop computer.
In the previous sections we have seen that a batteryless low-power implant electronic system is critical for realizing the RF implantable wireless telemetry [51, 52].
In the present study, we used GPS-based telemetry (±5 to 10 m precision) to track ring-billed gulls from this colony to reconstruct their movements at the landscape level.
Regardless of the cause, premature cessation of transmission is a key challenge to telemetry [33].
To overcome this problem a very recent study described the use of inter-animal telemetry [19].
Therefore, other complementary methods may be more effective for informing habitat usage such as acoustic surveys (for marine mammals [15], [16]) and satellite telemetry [17].
Most studies of grouping behaviour in sharks however, have been either observations on captive sharks, anecdotal or inferred through fishery capture records, or from conventional telemetry [8] [11].
Systolic blood pressure was measured throughout the study using tail-cuff plethysmography (Narco Bio-systems, Houston, TX) as previously described and validated versus telemetry [20].
