Unmanned aerial survey of elephants. [PDF]

PLoS ONE, 2013
The use of a UAS (Unmanned Aircraft System) was tested to survey large mammals in the Nazinga Game Ranch in the south of Burkina Faso. The Gatewing ×100™ equipped with a Ricoh GR III camera was used to test animal reaction as the UAS passed, and ...

Measuring the Luminance Contrast Sensitivity Function in Peripheral Vision

Color Research &Application, Volume 51, Issue 1, January/February 2026.
Luminance contrast detection thresholds of frequencies at eccentricities for a person. ABSTRACT We measured luminance contrast sensitivity functions (CSF) of four subjects by using Gabor stimuli up to 56°, 49°, 84°, and 63° in the nasal, superior, temporal, and inferior directions, respectively, of the left‐eye visual field.

Using optical vortex laser induced forward transfer to fabricate a twisted ferrite microcrystal array

APL Materials
We demonstrate direct printing from donor ink containing ferrite nanoparticles by employing laser induced forward transfer with an optical vortex possessing orbital angular momentum (OAM). We show, for the first time, that the as-printed dots are twisted

Low-Cost Panoramic Photogrammetry: A Case Study on Flat Textures and Poor Lighting Conditions

Geomatics
The article addresses the issue of panoramic photogrammetry for the reconstruction of interior spaces. Such environments often present challenges, including poor lighting conditions and surfaces with variable texture for photogrammetric scanning. In this

Conversion From Natural Broad‐Leaved Forest to Conifer Plantation Increases Relative Detritus Dependency of Aculeata Communities

Ecological Research, Volume 41, Issue 1, January 2026.
We compared the community structure of Aculeata bees and wasps in natural deciduous broadleaved forests and two coniferous plantations (Cryptomeria japonica, “Sugi” and Chamaecyparis obtusa, “Hinoki”) in southern Kyushu, Japan. Compared with natural forests, the dependence of Aculeata communities on the detritus‐based food chain increased in both ...

Leaf trichomes can alleviate water deficit stress and maintain diurnal photosynthesis by increasing leaf wetness and water absorption in Metrosideros polymorpha

Plant Species Biology, Volume 41, Issue 1, January 2026.
Leaf trichomes are often considered a key trait contributing to drought tolerance by increasing leaf wetness and enhancing foliar water uptake. However, their function has not been examined across a wide range of environmental conditions. Our field observations and manipulation experiments on Metrosideros polymorph—a species with trichomes that vary ...

The glandular hairs within the floral tube of Paederia foetida (Rubiaceae) and their influence on ant accessibility

Plant Species Biology, Volume 41, Issue 1, January 2026.
The glandular hairs in the floral tube of Paederia foetida has an effect on an ant's ability to enter a flower. Our results showed that trimming the glandular hairs increased the success rate of ants entering the floral tube. Abstract Hairs that grow on plant organs have been shown to play a variety of roles. Paederia foetida (Rubiaceae) is a perennial
