Drone‐based radiotelemetry and imagery systems provide an advantage over traditional techniques for estimating survival of dependent juveniles

open access: yesWildlife Society Bulletin, EarlyView.
We used drone‐based radiotelemetry and multispectral imagery to estimate detection and survival probabilities of blue‐winged teal broods in Saskatchewan, Canada. Weekly brood survival probabilities, estimated via Cormack‐Jolly‐Seber models, increased with age and were comparable between drone methods.

Explorer Satellite Electronics [PDF]

open access: yes, 1960
A discussion is presented of the design restrictions and the philosophy which enabled the Explorer satellites to be first during the IGY to reveal the presence of a belt of intense cosmic radiation encircling the earth's equator.

Lack of capture‐induced mortality of neonates associated with variation in handling protocols

open access: yesWildlife Society Bulletin, EarlyView.
We found that handling metrics (e.g., handling time, number of collectors, and age at capture) had limited or no influence on the survival of neonatal mule deer, desert bighorn sheep, and Rocky Mountain bighorn sheep within the first few days of life. Furthermore, we found that handled mule deer and Rocky Mountain bighorn neonates were recruited at a ...

GNSS Spoofing Detection via the Intersection Angle between Two Directions of Arrival in a Single Rotating Antenna

open access: yesSensors
Spoofing against the Global Navigation Satellite System (GNSS) is an attack with strong concealment, posing a significant threat to the security of the GNSS. Many strategies have been developed to prevent such attacks, but current detection methods based

Autumn Migration of Mississippi Flyway Mallards as Determined by Satellite Telemetry [PDF]

open access: yes, 2012
We used satellite telemetry to study autumn migration timing, routes, stopover duration, and final destinations of mallards Anas platyrhynchos captured the previous spring in Arkansas from 2004 to 2007.

Spatial Dynamics and Lifespan of Adult Cicadas After Fire and Logging: A Radiotracking Study

open access: yesIntegrative Zoology, EarlyView.
This study investigates the effects of wildfire and post‐fire salvage logging on the survival, spatial behavior, and habitat selection of Lyristes plebejus cicadas in Mediterranean pine forests. A total of 63 cicadas were captured, tagged with radio transmitters, and released in three disturbance contexts: burnt‐logged, burnt‐unlogged, and unburnt ...

The Wind of Change: Mapping Wind Energy Growth and Multi‐Species Vulnerability in Sardinia, Mediterranean

open access: yesAnimal Conservation, EarlyView.
The rapid expansion of wind energy across the Mediterranean region calls for more advanced tools to assess and mitigate its impacts on biodiversity. In this study, we present an innovative approach combining 13‐year satellite imagery analysis and ecological modelling, to assess the spatiotemporal overlap between wind energy development and habitat ...
