The uniformly most powerful invariant test for two models of detection function in point transect sampling

open access: yesStatistica, 2013
Estimating population abundance is of primary interest in wildlife population studies. Point transect sampling is a well established methodology for this purpose.

Scarless platysmaplasty for platysmal bands

open access: yesIndian Journal of Plastic Surgery, 2004
Transection of plastysmal bands has required a surgical approach that leaves scars and limits patient activities for a period of time. The author has developed a sirnple method to transect the platysmal bands under local anesthesia without resorting to ...

Assessing Site Disturbance Using Two Ground Survey Methods in a Mountain Forest

open access: yesCroatian Journal of Forest Engineering, 2010
Assessment of disturbance can provide forest managers with information to make appropriate decisions on site rehabilitation and monitoring. This paper evaluates the accuracy of successive estimates of site disturbance using two ground survey methods. The

Daily survival and dispersal of adult Rhagonycha fulva (Coleoptera: Cantharidae) in a wooded agricultural landscape

open access: yesEuropean Journal of Entomology, 2018
Studies of insect population under field conditions to establish survival rates, longevity and dispersal rates are rare in the literature. These types of studies are important and can be used to inform studies of the effects of landscape composition and ...

Estimating the density of raccoon dogs (Nyctereutes procyonoides) and water deer (Hydropotes inermis) using thermal real-time drone surveys and distance sampling

open access: yesScientific Reports
Accurate estimation of population density and spatial distribution is essential for wildlife conservation and management, yet conventional survey methods face substantial limitations.

Density estimation of sound-producing terrestrial animals using single automatic acoustic recorders and distance sampling

open access: yesAvian Conservation and Ecology, 2018
Obtaining accurate information on the distribution, density, and abundance of animals is an important first step toward their conservation. Methodological approaches using automatic acoustic recorders for species that communicate acoustically are gaining

A Novel Scouring Method to Monitor Nocturnal Mammals Using Uncrewed Aerial Vehicles and Thermal Cameras—A Comparison to Line Transect Spotlight Counts

open access: yesDrones, 2023
Wildlife abundance surveys are important tools for making decisions regarding nature conservation and management. Cryptic and nocturnal mammals can be difficult to monitor, and methods to obtain more accurate data on density and population trends of ...

Improved Estimation of Bird Abundance and Energy Consumption by Combining Point and Transect Observations

open access: yes, 2023
Abstract Point counts and transect surveys are both common methods for estimating bird abundance (by species, genus, or family) in a given environment. Sometimes both methods are used in the same study. Point counts reflect abundance directly, while transect observations of bird feeding instances reflect both the bird abundance and the ...

Surface horizons of forest soils for the diagnosis of soil environment contamination and toxicity caused by polycyclic aromatic hydrocarbons (PAHs).

open access: yesPLoS ONE, 2020
Polycyclic aromatic hydrocarbons (PAHs) are persistent organic pollutants that are released into soils primarily from the air, with wet and dry deposition.

Incentives Increase Participation in Mass Dog Rabies Vaccination Clinics and Methods of Coverage Estimation Are Assessed to Be Accurate. [PDF]

open access: yesPLoS Neglected Tropical Diseases, 2015
In this study we show that incentives (dog collars and owner wristbands) are effective at increasing owner participation in mass dog rabies vaccination clinics and we conclude that household questionnaire surveys and the mark-re-sight (transect survey ...
