Response of Bird Populations to Long-term Changes in Local Vegetation and Regional Forest Cover [PDF]

open access: yes, 2016
We analyzed data from a woodland site for a 59-year period to determine whether changes in bird populations are related to changes in the diversity and relative abundance of woody plant species even when vegetation structure, degree of forest ...

The Costs of Freely Granting Specific Performance [PDF]

open access: yes, 1982
For thousands of years the migratory birds has travelled across the earth in the same directions and returns to the same places generation through generation.

Preserve birds in their natural NZ habitat and save their “Wild Musick”. [PDF]

open access: yes, 2018
The Wild Musick framework has been created to support the Ministry of Business, Innovation and Employment (Tourism) NZ, Department of Conservation, Ministry of Conservation, and Ministry of Youth Development. It works to encourage the youth, and families

Photoconductivity‐Driven Quantum Efficiency Gain in Inorganic Ruddlesden‐Popper Layered Cs2PbBr2I2 Perovskite Photodetector for Visible Light Detection

open access: yesAdvanced Functional Materials, EarlyView.
Rational halogen mixing strategy was employed to shift the bandgap of Cs2PbBr2I2 from ultraviolet to visible region, enabling first realization of a visible‐light photodetector with this 2D layered Ruddlesden‐Popper perovskite material. Under illumination, light‐induced internal field forms and drives trap‐mediated persistent photoconductivity ...

Associations of Synoptic Weather Conditions With Nocturnal Bird Migration Over the North Sea

open access: yesFrontiers in Ecology and Evolution, 2020
The southern North Sea is part of an important flyway for nocturnal bird migration, but is also risky as it stretches over a large surface of water. Selecting nights with suitable weather conditions for migration can be critical for a bird’s survival ...

High individual repeatability of the migratory behaviour of a long-distance migratory seabird

open access: yesMovement Ecology, 2022
Background Understanding the evolution of migration requires knowledge of the patterns, sources, and consequences of variation in migratory behaviour, a need exacerbated by the fact that many migratory species show rapid population declines and require ...

Beyond Earth: Resilience of Quasi‐2D Perovskite Solar Cells in Space

open access: yesAdvanced Materials, EarlyView.
In the article (DOI: 10.1002/adma.202520433), Christoph Putz and co‐workers demonstrate rigid quasi‐2D perovskite solar cells operating in low Earth orbit, delivering stable power for more than 100 days under real‐space conditions. In‐orbit performance is correlated with extensive ground‐based thermal and proton‐irradiation studies on rigid and ...

Automatic detection of migrating soaring bird flocks using weather radars by deep learning

open access: yesMethods in Ecology and Evolution, 2023
The use of weather radars to detect and distinguish between different biological patterns greatly improves our understanding of aeroecology and its consequences for our lives.

Bird migration: Flying high to avoid overheating?

open access: yesCurrent Biology, 2021
Acts of flight have always baffled humans. Recent tracking studies of birds only add to the awe and mystery. A new study shows that migrating great snipes fly high - over two kilometres high - during the day and lower at night. Why?

Information Transmission Strategies for Self‐Organized Robotic Aggregation

open access: yesAdvanced Robotics Research, EarlyView.
In this review, we discuss how information transmission influences the neighbor‐based self‐organized aggregation of swarm robots. We focus specifically on local interactions regarding information transfer and categorize previous studies based on the functions of the information exchanged.
