Shifts in vegetation phenology along flyways entail varying risks of mistiming in a migratory songbird

Ecosphere, 2016
Long‐term shifts in vegetation phenology generally follow the pattern of global warming. Yet, topographical complexity and biome diversity cause uneven spatial trends in the phenological response of vegetation to climate change.

Cold spell en route delays spring arrival and decreases apparent survival in a long-distance migratory songbird

BMC Ecology, 2017
Background Adjusting the timing of annual events to gradual changes in environmental conditions is necessary for population viability. However, adaptations to weather extremes are poorly documented in migratory species.

BirdVoxDetect: Large-Scale Detection and Classification of Flight Calls for Bird Migration Monitoring

IEEE/ACM Transactions on Audio Speech and Language Processing
Sound event classification has the potential to advance our understanding of bird migration. Although it is long known that migratory species have a vocal signature of their own, previous work on automatic flight call classification has been limited in ...

Estimates of aerial vertebrate mortality at wind farms in a bird migration corridor and bat diversity hotspot

, 2020
Three major flyways of the Nearctic – Neotropical bird migration system converge at the coastal plains of the Isthmus of Tehuantepec, Mexico. Approximately one million vultures and raptors traverse the area during the autumn migration season, and more ...

Hybrid Ferroelectric Tunnel Junctions with Intrinsic Nonlinearity and Self‐Rectification via Interfacial Reconstruction

Advanced Functional Materials, EarlyView.
Rapid thermal annealing reconstructs the BCFO/Nb:STO interface into an atomically thin reconstructed interfacial layer, which reshapes the tunneling barrier and converts a high‐TER ferroelectric tunnel junction into an intrinsically nonlinear, self‐rectifying device.

Influence of temperature and rainfall on the timing of the spring migration of Eurasian Wren Troglodytes troglodytes through the southern Baltic coast

The European Zoological Journal
Climate factors shape the spring phenology of migrant birds in Europe. We examined carry-over effects of temperature and rainfall in four regions of Europe on the spring migration timing of a medium-distance migrant, Eurasian Wren, at the southern Baltic

Information Transmission Strategies for Self‐Organized Robotic Aggregation

Advanced 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.
