What are the issues with presence‐absence data for wildlife managers?

DI MacKENZIE - The Journal of Wildlife Management, 2005 - Wiley Online Library
Presence‐Absence data can be useful to wildlife managers in a wide variety of contexts,
from monitoring populations at large spatial scales to identifying habitats that are of high …

Precision and bias of methods for estimating point survey detection probabilities

BA Wintle, MA McCarthy, KM Parris… - Ecological …, 2004 - Wiley Online Library
Wildlife surveys often seek to determine the presence or absence of species at sites. Such
data may be used in population monitoring, impact assessment, and species–habitat …

Absent or undetected? Effects of non-detection of species occurrence on wildlife–habitat models

W Gu, RK Swihart - Biological conservation, 2004 - Elsevier
Presence–absence data are used widely in analysis of wildlife–habitat relationships. Failure
to detect a species' presence in an occupied habitat patch is a common sampling problem …

Efficient species‐level monitoring at the landscape scale

BR Noon, LL Bailey, TD Sisk… - Conservation …, 2012 - Wiley Online Library
Monitoring the population trends of multiple animal species at a landscape scale is
prohibitively expensive. However, advances in survey design, statistical methods, and the …

Detecting population declines over large areas with presence‐absence, time‐to‐encounter, and count survey methods

JF Pollock - Conservation Biology, 2006 - Wiley Online Library
Ecologists often discount presence‐absence surveys as a poor way to gain insight into
population dynamics, in part because these surveys are not amenable to many standard …

Improving precision and reducing bias in biological surveys: estimating false‐negative error rates

AJ Tyre, B Tenhumberg, SA Field… - Ecological …, 2003 - Wiley Online Library
The use of presence/absence data in wildlife management and biological surveys is
widespread. There is a growing interest in quantifying the sources of error associated with …

Modelling distribution and abundance with presence‐only data

JL Pearce, MS Boyce - Journal of applied ecology, 2006 - Wiley Online Library
Summary 1 Presence‐only data, for which there is no information on locations where the
species is absent, are common in both animal and plant studies. In many situations, these …

Modeling the probability of resource use: the effect of, and dealing with, detecting a species imperfectly

DI Mackenzie - The Journal of Wildlife Management, 2006 - Wiley Online Library
Resource‐selection probability functions and occupancy models are powerful methods of
identifying areas within a landscape that are highly used by a species. One common …

Estimating population density from presence–absence data using a spatially explicit model

DSL Ramsey, PA Caley… - The Journal of Wildlife …, 2015 - Wiley Online Library
ABSTRACT Presence–absence (detection/non‐detection) data are routinely collected in
wildlife studies where identification of individuals is impossible or impractical and where the …

Accounting for imperfect detection and survey bias in statistical analysis of presence‐only data

RM Dorazio - Global Ecology and Biogeography, 2014 - Wiley Online Library
Aim During the past decade ecologists have attempted to estimate the parameters of
species distribution models by combining locations of species presence observed in …
