Moving I`iwi (Vestiaria coccinea) as a Surrogate for Future Translocations of Endangered `Akohekohe (Palmeria dolei) [PDF]

open access: yes, 2010
Translocations often play an important role in the recovery of endangered species. To assess feasibility for translocation of endangered `Akohekohe (Palmeria dolei), we conducted an experimental translocation of I`iwi (Vestiaria coccinea) from east to ...

Evidence for West Nile Virus and Usutu Virus Infections in Wild and Resident Birds in Germany, 2017 and 2018 [PDF]

open access: yes, 2019
Wild birds play an important role as reservoir hosts and vectors for zoonotic arboviruses and foster their spread. Usutu virus (USUV) has been circulating endemically in Germany since 2011, while West Nile virus (WNV) was first diagnosed in several bird ...

Self‐Aligned Waveguide Array Integrated with Flat Microlenses for Environment‐Adaptive and High‐Resolution Compound Eye Vision

open access: yesAdvanced Optical Materials, EarlyView.
For an amphibious high‐resolution compound eye vision system, environment‐adaptive self‐aligned waveguides are integrated with high‐density flat microlenses. Fabrication, optical performance, and environmental adaptability are investigated, demonstrating stable focusing, efficient light collection, and enhanced spatial resolution.

Occurrence of Fungi on Duck Egg Shells and Drug Resistance Analysis of Aspergillus spp. Isolates

open access: yesApplied Sciences
Fungi are a typical part of the microbiome of poultry houses, but some of the genera can be pathogenic for poultry and humans. An investigation was conducted on 200 duck eggs from 10 flocks to determine total fungal contamination on the eggshells.

Effect of Nanoparticle Distribution on Photothermal Absorption in Binary Mixtures of Colloidal Supraballs

open access: yesAdvanced Photonics Research, EarlyView.
This work combines molecular dynamics and finite‐difference time‐domain computational approaches to study the photothermal properties of melanin nanoparticle–based supra‐assemblies. Based on the results of this study, the binary mixtures of melanin and silica with higher concentrations of melanin and with more segregated levels of mixing are able to ...

Vision‐Assisted Avocado Harvesting with Aerial Bimanual Manipulation

open access: yesAdvanced Robotics Research, EarlyView.
This work outlines the design and implementation of a bimanual aerial robot that employs visual perception and learning to detect, reach, and harvest avocados. A new gripper and fixer arm assembly is used to harvest avocados, while visual perception enables the detection of avocados and estimation of their position and orientation for determining ...

Influence of rearing environment on development of perching and dustbathing behaviour in laying hens [PDF]

open access: yes, 2007
Studies have shown that perching and dustbathing behaviour in birds can be affected by how and when the behaviour develops. With the increasing trend away from cages and towards keeping laying hens in larger, more complex housing systems, it is important
