Satellite Tracking of Adult and Immature Eastern Imperial Eagles

open access: yesПернатые хищники и их охрана, 2018
Four adult males, two adult females and two immature Imperial Eagles were trapped near Taif in Saudi Arabia close to the Red Sea while wintering. Three of theses eagles were trapped up to three times.

Using birds of prey to manage pest bird flocks under lethal and non-lethal conditions – A review

open access: yesRaptor Journal
Raptors have been successfully used to disperse and often control flocks of pest birds. However, the question that has not been resolved is, “If the raptor kills a small number of the target flock, does this improve the efficiency of control?” This mini ...

Patterns of energy acquisition by penguins: benefits of alternating short and long foraging trips. [PDF]

open access: yes, 2004
In some seabirds, foraging trips have been defined as either long or short, with the length of time spent traveling to the foraging area apparently a critical feature in determining foraging trip length.

Silicon‐Integrated Next‐Generation Plasmonic Devices for Energy‐Efficient Semiconductor Applications

open access: yesAdvanced Materials Technologies, EarlyView.
Silicon (Si)‐integrated plasmonics offer a pathway to next‐generation, energy‐efficient semiconductor applications. This review highlights advances using complementary metal–oxide–semiconductor (CMOS)‐compatible materials like transparent conductive oxides and novel architectures, particularly coupled hybrid plasmonic waveguides (CHPWs).

Behaviourally mediated predation avoidance in penguin prey: in situ evidence from animal-borne camera loggers [PDF]

open access: yesRoyal Society Open Science, 2018
Predator dietary studies often assume that diet is reflective of the diversity and relative abundance of their prey. This interpretation ignores species-specific behavioural adaptations in prey that could influence prey capture.

Harvesting and Conversation in a Predator-Prey System [PDF]

open access: yes, 2001
Optimal harvesting of prey in a predator-prey ecosystem is studiedunder the condition that the existence of the predator has value. Predators (birds) and humans (fishers) compete for prey (shellfish).

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 ...

The Annual Cycle of German Adult Ospreys – Studies in the Breeding and Wintering Areas as Well as During Migration Since 1995 by Means of Satellite Telemetry

open access: yesПернатые хищники и их охрана, 2018
German Ospreys (Pandion haliaetus) were thought to migrate to sub-Saharan Africa. However, most of the many ring recoveries were from juvenile birds, and adults had never been satellite-tracked.
