Biodiversity estimates from different camera trap surveys: a case study from Osogovo Mt., Bulgaria

Nature Conservation Research: Заповедная наука, 2018
Inventorying mammal assemblages is vital for their conservation and management, especially when they include rare or endangered species. However, obtaining a correct estimation of the species diversity in a particular area can be challenging due to ...

Density Estimation of Unmarked Populations Using Camera Traps in Heterogeneous Space

Wildlife Society Bulletin, 2020
Camera traps are commonly used to monitor animal populations, but statistical estimators of density from camera‐trap data for species that cannot be individually identified are still in development, and few models take space use into account.

Camera‐trapping version 3.0: current constraints and future priorities for development

Remote Sensing in Ecology and Conservation, 2019
Camera traps are a widely used tool in wildlife research and conservation, but in situ factors such as theft, poor performance in extreme environments and damage by wildlife may be hindering the effectiveness of the technology.

Using camera traps to estimate ungulate abundance: a comparison of mark–resight methods

Remote Sensing in Ecology and Conservation, 2022
Many global wildlife populations are experiencing unprecedented declines. Estimates of population abundance are needed to effectively manage common species and to conserve vulnerable species.

Automated distance estimation for wildlife camera trapping

Ecological Informatics, 2022
The ongoing biodiversity crisis calls for accurate estimation of animal density and abundance to identify sources of biodiversity decline and effectiveness of conservation interventions. Camera traps together with abundance estimation methods are often employed for this purpose.

Mammal population density estimation using camera traps based on a random encounter model: theoretical basis and practical recommendations

Nature Conservation Research: Заповедная наука, 2023
Estimating the population density of mammals has long been one of the problematic tasks of both fundamental population ecology and practical programmes for their conservation and management. The majority of methods for population density estimation using

Camera trapping of large mammals in Yenice Forest, Turkey: local information versus camera traps [PDF]

Oryx, 2009
Abstract Information on large mammals in Turkey is limited, and widely applicable, reliable field methods need to be used to gather appropriate data for conservation and management. To evaluate local information on mammal species we conducted interview and ground surveys, followed by a camera trap survey, during January–May 2006 in Yenice Forest, a ...

Matrix metalloproteinase‐9 regulates cell adhesion and membrane protrusive activity of ovarian cancer cells

FEBS Open Bio, EarlyView.
Matrix metalloproteinase‐9 (MMP9) drives ovarian cancer progression. Using MMP9‐null cells (M9‐KO) created from ovarian cancer cells, we found MMP9 loss did not block Epidermal Growth Factor (EGF)‐driven E‐cadherin dissolution or EMT but delayed and reduced EGF‐driven membrane protrusions. Transient MMP9 re‐expression drove membrane protrusion.

Camtrap DP: an open standard for the FAIR exchange and archiving of camera trap data

Remote Sensing in Ecology and Conservation
Camera trapping has revolutionized wildlife ecology and conservation by providing automated data acquisition, leading to the accumulation of massive amounts of camera trap data worldwide. Although management and processing of camera trap‐derived Big Data

Targeting burrows improves detection in giant pangolin Smutsia gigantea camera-trap surveys

Oryx
The Endangered giant pangolin Smutsia gigantea is rare and elusive across its Central African range. Because of its solitary and nocturnal nature, the species is difficult to study and so its ecology is little known.
