Title
Estimating cue production rates to support passive acoustic density estimates: learning from cetaceans
Abstract
Many animals produce sounds which can be detected by acoustic sensors, hydrophones on water and microphones in air. Given several shortcomings of visual based methods, for some groups of animals, passive acoustics might be an ideal method for monitoring wild populations. In the last decade, passive acoustic density estimation has been replacing traditional visual surveys for some groups of cetaceans, in particular echolocating deep divers hard to survey visually. We present an introduction to passive acoustic density estimation, in particular cue counting, where sounds of interested are used to estimate animal density. We narrow our focus on the fundamental aspect of cue rates, that is, the number of sounds produced per animal per unit time, a fundamental quantity required to convert the number of sounds detected in a set of sensors into an estimate of animal abundance. The bulk of the talk will provide examples drawn from ACCURATE, an ongoing project that hopes to synthesize the existing knowledge about cue rate production and estimation in cetaceans. Examples will include narwhals, beaked whales, and sperm whales. We will try to make it an interesting talk for biologists and ecologists and statisticians alike, and since many animals besides cetaceans produce sounds, it might be interesting to anyone interested in estimating animal abundance.
Biography
BSc in Biology (University of Lisbon, UL), MSc in Probability and Statistics (UL) and PhD in
Statistics in 2007 (University of St Andrews, UStA). Working at CREEM, UStA, as a Senior
Research Fellow. Interested in animal abundance estimation, focused on passive acoustic data, but also in the wider use of statistics in ecology and statistical literacy. Has written +100 papers applying a suite of statistical methods, mostly under ecological contexts. He is an invited professor at the department of Animal Biology of the Faculty of Sciences UL, where he teaches statistics to biologists.

Buenos dias,Este jueves un poquito antes de la comida, Tiago Marques nos va hablar de como podemos saber cuantas baleas hay 'escuchando' los Océanos o sea, del proyecto ACCURATE, de aplicaciones de acústica y sobretodo un poquito de estadística aplicada a Ecología.Así empezamos con las palestras del IRSE, (esta que será conjunta con IPMA en formato on-line).Hasta jueves,Marta y Maria GraziaEl link para el evento:https://videoconf-colibri.zoom.us/j/91404148973?pwd=THBLL2xjeFlsRU5RSy9jdHY4UFljUT09
