Flight metabolic rate and Pgi genotype influence butterfly dispersal rate in the field.
Dispersal is a key life-history trait, especially in species inhabiting fragmented landscapes. The process of dispersal is affected by a suite of morphological, physiological, and behavioral traits,Expand
Flight Orientation Behaviors Promote Optimal Migration Trajectories in High-Flying Insects
Not at the Mercy of the Wind How can insects that migrate at high altitudes on fast-moving winds influence their direction of migration, when wind speeds typically exceed their self-propelled airExpand
Vertical-Looking Radar: A New Tool for Monitoring High-Altitude Insect Migration
Abstract Many insect species engage in high-altitude, wind-borne migration, often several hundred meters above the ground. At these heights they can use the wind to travel tens or hundreds ofExpand
High‐altitude migration of the diamondback moth Plutella xylostella to the U.K.: a study using radar, aerial netting, and ground trapping
Abstract 1. The high‐altitude wind‐borne migration of the diamondback moth Plutella xylostella in the U.K. in 2000 was investigated (a) by direct monitoring of insect flight by vertical‐looking radarExpand
Adequacy of Some Important Browse Species In Overwintering of Mule Deer.
Winter is a critical period for game animals in temperate climates. During this season food supplies are at or near their minimum; cold and inclement weather puts stresses on the bodily functions ofExpand
Displaced honey bees perform optimal scale-free search flights.
Honey bees (Apis mellifera) are regularly faced with the task of navigating back to their hives from remote food sources. They have evolved several methods to do this, including compass-directedExpand
Honeybees perform optimal scale-free searching flights when attempting to locate a food source
We show that when a food source at a known location ceases to be available, flying insects will exhibit search patterns that optimise the rediscovery of such resources. Expand
Tracking butterfly movements with harmonic radar reveals an effect of population age on movement distance
We used harmonic radar to track freely flying Glanville fritillary butterfly (Melitaea cinxia) females within an area of 30 ha. Butterflies originated from large and continuous populations in ChinaExpand
Tracking butterfly flight paths across the landscape with harmonic radar
For the first time, the flight paths of five butterfly species were successfully tracked using harmonic radar within an agricultural landscape. Until now, butterfly mobility has been predominantlyExpand
Radar Tracking and Motion-Sensitive Cameras on Flowers Reveal the Development of Pollinator Multi-Destination Routes over Large Spatial Scales
Automated tracking of bumblebees and computer simulations reveal how bees locate a series of flowers and optimize their routes to visit them all.
