Visual survey by divers using open-circuit (OC) SCUBA is the most widely used approach to survey coral reef fishes. Therefore, it is important to quantify sources of bias in OC surveys, such as the possibility that avoidance of OC divers by fishes can lead to undercounting in areas where targeted species have come to associate divers with a risk of being speared. One potential way to reduce div...

Underwater ultrasonic sound of finless porpoises Neophocaena phocaenoides were monitored concurrent with visual observations in the Yangtze River, China. In a total of a 774 km cruise, 588 finless porpoises were sighted by visual observation and 44,864 ultrasonic pulses were recorded. The acoustic monitoring system could detect presence of the finless porpoises 82% of the time. False alarms in ...

and oculomotor control mechanisms during scanning eye movements is of particular importance to visual neurobiologists. Just as our eyes are unable to simultaneously fixate all the elements contained within a scene, our perception Princeton, New Jersey 08544 2 Systems Neurobiology Laboratory of those elements is likewise limited. The tremendous volume of information impinging on the retina impos...

This paper presents a survey registration framework to assist in the recurrent inspection of a natural environment. Our framework coarsely aligns surveys at the image–level using visual SLAM, and it registers images at the pixel–level using SIFT Flow, which enables rapid manual inspection. The variation in appearance of natural environments make data association a primary challenge of this work...

Documenting biodiversity, species occurrence, and status require reliable monitoring techniques, but the complex life history cryptic behavior of many anurans create challenges for conventional approaches. Environmental DNA (eDNA) surveys are a promising alternative (or complement) to anuran monitoring, their relative success has not been fully tested. We assessed comparative efficacy targeted ...
