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.

Using by‐catch data from wildlife surveys to quantify climatic parameters and timing of phenology for plants and animals using camera traps

Remote Sensing in Ecology and Conservation, 2020
Gaining a better understanding of global environmental change is an important challenge for conserving biodiversity. Shifts in phenology are an important consequence of environmental change.

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 ...

Biomimetic Iridescent Skin: Robust Prototissues Spontaneously Assembled from Photonic Protocells

Advanced Functional Materials, EarlyView.
Uniform nanoparticles are induced to form arrays (photonic crystals) in the cores of biopolymer capsules, endowing these ‘protocells’ with structural color. These protocells are then assembled into large self‐standing objects, i.e., prototissues, with robust mechanical properties as well as iridescent optical properties.

Single-atom trapping in holographic 2D arrays of microtraps with arbitrary geometries

, 2014
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 ...

Particle tracking stereomicroscopy in optical tweezers: control of trap shape [PDF]

, 2010
We present an optical system capable of generating stereoscopic images to track trapped particles in three dimensions. Two-dimensional particle tracking on each image yields three dimensional position information.

An Open Standard for Camera Trap Data [PDF]

Biodiversity Data Journal, 2016
Camera traps that capture photos of animals are a valuable tool for monitoring biodiversity. The use of camera traps is rapidly increasing and there is an urgent need for standardization to facilitate data management, reporting and data sharing. Here we offer the Camera Trap Metadata Standard as an open data standard for storing and sharing camera trap

Reconfigurable Magnetic Soft Microrobot for Acoustically Triggered Targeted Bacterial Sterilization

Advanced Functional Materials, EarlyView.
Reconfigurable magnetic soft microrobots integrate in situ‐grown piezoelectric zinc oxide nanorods that produce reactive oxygen species upon acoustic excitation. Combining magnetically guided transport with thermally induced planar reconfiguration, the microrobots achieve targeted delivery and enhanced bacterial sterilization through efficient on ...
