Camera trapping as a method for estimating abundance of Mexican wolves
Estimating wildlife abundance, particularly for rare and elusive species, is challenging because of time, cost, and methodological constraints. The Mexican wolf (Canis lupus baileyi), a federally‐listed endangered subspecies of gray wolf, is currently ...

Although arboreal camera trapping is a growing field, it has rarely been used for monitoring plant‐frugivore interactions in the trees. Frugivore foraging behavior generally occurs in trees, hence arboreal camera trapping can be a potentially useful tool

SOCRATES: Introducing Depth in Visual Wildlife Monitoring Using Stereo Vision
The development and application of modern technology are an essential basis for the efficient monitoring of species in natural habitats to assess the change of ecosystems, species communities and populations, and in order to understand important drivers ...

Single-atom trapping in holographic 2D arrays of microtraps with arbitrary geometries [PDF]
We demonstrate single-atom trapping in two-dimensional arrays of microtraps with arbitrary geometries. We generate the arrays using a Spatial Light Modulator (SLM), with which we imprint an appropriate phase pattern on an optical dipole trap beam prior ...

Use of camera trapping in determining Iberian lynx population parameters: The use area and its limitations [PDF]
Below are the results of the survey of the Iberian lynx obtained with camera-trapping between 2000 and 2007 in Sierra Morena. Two very important aspects of camera-trapping concerning its efficiency are also analyzed.

Assessing the status of wild felids in a highly-disturbed commercial forest reserve in Borneo and the implications for camera trap survey design. [PDF]
The proliferation of camera-trapping studies has led to a spate of extensions in the known distributions of many wild cat species, not least in Borneo. However, we still do not have a clear picture of the spatial patterns of felid abundance in Southeast ...

An open-access platform for camera-trapping data [PDF]
In southern Mexico, local communities have been playing important roles in the design and collection of wildlife data through camera-trapping in community-based monitoring of biodiversity projects. However, the methods used to store the data have limited

Low-cost optical manipulation using hanging droplets of PDMS [PDF]
We propose and demonstrate a low-cost optical micromanipulation system that makes use of simple microfrabricated components coupled to a smartphone camera for imaging. Layering hanging droplets of polydimethylsiloxane (PDMS) on microscope coverslips, and

Distance sampling with camera traps [PDF]
* Reliable estimates of animal density and abundance are essential for effective wildlife conservation and management. Camera trapping has proven efficient for sampling multiple species, but statistical estimators of density from camera trapping data for species that cannot be individually identified are still in development. * We extend point-transect

Free-roaming domestic cats (Felis catus) pose numerous risks to biodiversity conservation, especially in island ecosystems. However, the removal of cats is costly, labor-intensive, and often demands more resources than land managers have at their ...
