Experimental Investigation of Observation Error in Anuran Call Surveys

JOURNAL OF WILDLIFE MANAGEMENT, 74(8), 1882–1893.

By: B. Mcclintock*, L. Bailey*, K. Pollock n & T. Simons*

author keywords: auditory detection; aural detection; detection probability; false negative; false positive; imperfect detection; monitoring; site occupancy; species occurrence
TL;DR: Recommend practices to mitigate for false positives when developing occupancy monitoring protocols that rely on auditory detections are recommended, including additional observer training, limiting the number of target species, and establishing distance and ambient noise thresholds during surveys.

2010 journal article

Unmodeled observation error induces bias when inferring patterns and dynamics of species occurrence via aural detections

ECOLOGY, 91(8), 2446–2454.

By: B. McClintock*, L. Bailey*, K. Pollock n & T. Simons n

author keywords: auditory detection; colonization; detection probability; false negative; false positive; imperfect detection; local extinction; measurement error; monitoring; observation error; site occupancy; species occurrence
MeSH headings : Animals; Anura / physiology; Hearing; Humans; Models, Theoretical; Observer Variation; Population Density; Population Dynamics; Vocalization, Animal / physiology
TL;DR: It is argued that all forms of observation error, including false positive errors and heterogeneous detection probabilities, must be incorporated into the estimation framework to facilitate reliable inferences about occupancy and its associated vital rate parameters. (via Semantic Scholar)

2006 journal article

Estimating site occupancy and detection probability parameters for meso- and large mammals in a coastal ecosystem

JOURNAL OF WILDLIFE MANAGEMENT, 70(6), 1625–1633.

By: N. Talancy, L. Bailey n, J. Sauer*, R. Cook & A. Gilbert*

author keywords: Cape Cod; detection probability; mammals; monitoring; multispecies; nondetection; presence-absence; site occupancy
TL;DR: It is believed that site occupancy is a useful state variable and suggest that monitoring programs for mammals using occupancy data consider detectability prior to making inferences about species distributions or population change. (via Semantic Scholar)

2006 journal article

Estimating the abundance of mouse populations of known size: Promises and pitfalls of new methods

ECOLOGICAL APPLICATIONS, 16(2), 829–837.

By: P. Conn*, A. Arthur*, L. Bailey n & G. Singleton*

author keywords: abundance estimation; Huggins-Alho model; MARK; mark-recapture; model averaging; Mus musculus; Pledger model
TL;DR: It is found that mark-recapture methods employing individual covariates yielded satisfactory abundance estimates for most populations, while model sets with heterogeneity formulations consisting solely of mixture distributions did not perform well for several of the populations.

2004 journal article

Assessing the fit of site-occupancy models

JOURNAL OF AGRICULTURAL BIOLOGICAL AND ENVIRONMENTAL STATISTICS, 9(3), 300–318.

By: D. MacKenzie & L. Bailey n

author keywords: goodness-of-fit; model fit; patch occupancy; Plethodon glutinosus; Plethodon oconluftee
TL;DR: Evidence is found that the most global model considered provides a poor fit to the data, hence an overdispersion factor is estimated to adjust model selection procedures and inflate standard errors. (via Semantic Scholar)

Comparing population size estimators for plethodontid salamanders

JOURNAL OF HERPETOLOGY, 38(3), 370–380.

By: L. Bailey*, T. Simons* & K. Pollock n

TL;DR: Results indicate that short-term closed-population, robust design, and depletion methods estimate surface population of salamanders (i.e., those near the surface and available for capture during a given sampling occasion) and that in longer duration studies, temporary emigration violates assumptions of both open- and closed- Population mark-recapture estimation models.

Estimating site occupancy and species detection probability parameters for terrestrial salamanders

ECOLOGICAL APPLICATIONS, 14(3), 692–702.

By: L. Bailey n, T. Simons n & K. Pollock n

author keywords: amphibian; detection probability; Great Smoky Mountains National Park; monitoring; plethodontid salamanders; site occupancy
TL;DR: A new method to estimate proportion of area occupied using detection/nondetection data from a terrestrial salamander system in Great Smoky Mountains National Park finds that time and large-scale habitat characteristics were important covariates in estimates of both proportion of Area occupied and detection probability.

Estimating survival and breeding probability for pond-breeding amphibians: A modified robust design

ECOLOGY, 85(9), 2456–2466.

By: L. Bailey n, W. Kendall, D. Church* & H. Wilbur*

author keywords: Ambystoma tigrinum; capture-recapture; detection probability; multistate models; pond-breeding amphibians; survival probability; temporary emigration; unobservable state
TL;DR: A multistate mark–recapture model is developed, using an open-robust design that permits one entry and one exit from the study area per season, and extends previous temporary emigration models (MSMR with an unobservable state). (via Semantic Scholar)

2004 journal article

Investigating species co-occurrence patterns when species are detected imperfectly

JOURNAL OF ANIMAL ECOLOGY, 73(3), 546–555.

By: D. MacKenzie*, L. Bailey n & J. Nichols

author keywords: detectability; Great Smoky Mountains National Park; likelihood; occupancy; Plethodon jordani; Plethodon glutinosus complex
TL;DR: A statistical method for modelling co-occurrence patterns between species while accounting for imperfect detection and site characteristics is presented and some evidence of a statistical interaction between species in terms of detectability is found that may be due to changes in relative abundances.

Large scale wildlife monitoring studies: statistical methods for design and analysis

Pollock, K. H., Nichols, J. D., Simons, T. R., Farnsworth, G. L., Bailey, L. L., & Sauer, JR. (2002, March). ENVIRONMETRICS, Vol. 13, pp. 105–119.

By: K. Pollock n, J. Nichols*, T. Simons n, G. Farnsworth n, L. Bailey n & . Sauer*

author keywords: absolute abundance; capture-recapture sampling; detection probability; distance sampling; long-term monitoring; relative abundance; removal sampling; wildlife monitoring studies
TL;DR: Basic concepts based on actual avian, amphibian, and fish monitoring studies are presented in this article and it is believed that the estimation of detection probability should be built into the monitoring design through a double sampling approach. (via Semantic Scholar)
