Biological Earth observation with animal sensors

, 2022
Space-based tracking technology using low-cost miniature tags is now delivering data on fine-scale animal movement at near-global scale. Linked with remotely sensed environmental data, this offers a biological lens on habitat integrity and connectivity ...

Animal migration: linking models and data beyond taxonomic limits

, 2009
An international workshop on animal migration was held at the Lorentz Center in Leiden, The Netherlands, 2–6 March 2009, bringing together leading theoreticians and empiricists from the major migratory taxa, aiming at the identification of cutting-edge ...

Avian Immunome DB: an example of a user-friendly interface for extracting genetic information

BMC Bioinformatics, 2020
Background Genomic and genetic studies often require a target list of genes before conducting any hypothesis testing or experimental verification. With the ever-growing number of sequenced genomes and a variety of different annotation strategies, comes ...

Ontogenetic niche shifts as a driver of seasonal migration [PDF]

, 2020
Ontogenetic niche shifts have helped to understand population dynamics. Here we show that ontogenetic niche shifts also offer an explanation, complementary to traditional concepts, as to why certain species show seasonal migration.

Intensive hunting changes human-wildlife relationships [PDF]

PeerJ, 2022
Wildlife alter their behaviors in a trade-off between consuming food and fear of becoming food themselves. The risk allocation hypothesis posits that variation in the scale, intensity and longevity of predation threats can influence the magnitude of ...

Timing avian long-distance migration: from internal clock mechanisms to global flights [PDF]

, 2017
Migratory birds regularly perform impressive long-distance flights, which are timed relative to the anticipated environmental resources at destination areas that can be several thousand kilometres away.

The Monarch Butterfly as a Model for Understanding the Role of Environmental Sensory Cues in Long-Distance Migratory Phenomena

Frontiers in Behavioral Neuroscience, 2020
The awe-inspiring annual migration of monarch butterflies (Danaus plexippus) is an iconic example of long-distance migratory phenomena in which environmental sensory cues help drive successful migration. In this mini-review article, I begin by describing

Opposition-Based Animal Migration Optimization [PDF]

Mathematical Problems in Engineering, 2013
AMO is a simple and efficient optimization algorithm which is inspired by animal migration behavior. However, as most optimization algorithms, it suffers from premature convergence and often falls into local optima. This paper presents an opposition-based AMO algorithm. It employs opposition-based learning for population initialization and evolution to

Home on the Range: Factors Explaining Partial Migration of African Buffalo in a Tropical Environment

, 2012
Partial migration (when only some individuals in a population undertake seasonal migrations) is common in many species and geographical contexts. Despite the development of modern statistical methods for analyzing partial migration, there have been no ...

Time synchronisation for millisecond-precision on bio-loggers

Movement Ecology
Time-synchronised data streams from bio-loggers are becoming increasingly important for analysing and interpreting intricate animal behaviour including split-second decision making, group dynamics, and collective responses to environmental conditions ...
