Contrasting Effects of Grooming by Galápagos Mockingbirds on Parasitic Lice and Feather Mites

Austin R. Clayton, Sarah E. Bush, Matthew M. Waller, Dale H. Clayton

Grooming is the first line of defense against ectoparasites by birds. Avian grooming consists of preening with the bill and scratching with the feet. Captive birds are effective at controlling ectoparasites by grooming. However, the effectiveness of grooming for controlling parasites of …

PREVALENCE AND INTENSITY OF PARASITIC INSECTS ON PUERTO RICAN BIRDS

Matthew M. Waller, Nicole A. Amedee, Hannah M. Warr, Sarah E Bush et autres

Birds are host to four orders of parasitic insects: flies (Diptera), lice (Psocodea: Phthiraptera), true bugs (Hemiptera), and fleas (Siphonaptera). These parasites can lower host fitness and thus require birds to invest in defenses to minimize fitness losses. In Puerto Rico, virulent …

Kinship Analysis Confirms Tolerant Galapagos Mockingbirds Are a Source of Nest Flies That Threaten Darwin's Finches

Matthew M. Waller, Sarah E. Bush, Andrew D. Sweet, Dale H. Clayton

Host species have evolved different strategies for dealing with parasites. 'Vulnerable' hosts, which suffer reduced fitness from parasites, are under selection to evolve defences. 'Tolerant' hosts, by contrast, avoid reductions in fitness by mitigating parasite damage. When tolerant and vulnerable hosts co-occur, …

Quantifying resolution limits in pedestal profile measurements with Gaussian process regression

N.M. Cao, David R. Hatch, Craig Michoski, Todd Oliver et autres

Abstract Edge transport barriers in magnetically confined fusion plasmas, commonly known as pedestals, play a crucial role in achieving high confinement plasmas. However, their defining characteristic, a steep rise in plasma pressure over short length scales, makes them challenging to diagnose experimentally. …

Quantifying Resolution Limits in Pedestal Profile Measurements with Gaussian Process Regression

N.M. Cao, David R. Hatch, Craig Michoski, Todd Oliver et autres

Edge transport barriers (ETBs) in magnetically confined fusion plasmas, commonly known as pedestals, play a crucial role in achieving high confinement plasmas. However, their defining characteristic, a steep rise in plasma pressure over short length scales, makes them challenging to diagnose experimentally. …

Grooming time parallels molt intensity in wild‐caught feral rock pigeons

Paula Guzmán‐Delgado, Nicole A. Amedee, Hannah M. Warr, Ruby J. Linnell et autres

Feathers are critical for locomotion, communication, thermoregulation, waterproofing, and protection from UV radiation. To maintain these functions, birds care for their feathers by grooming, which consists of preening with the bill and scratching with the feet. Grooming cleans and arranges feathers, distributes …

Birds in arid regions have depauperate louse communities: Climate change implications?

Sarah E. Bush, Matthew M. Waller, Kyle M. Davis, Sonora F. Clayton et autres

Environmental factors such as temperature and humidity influence the distribution of free-living organisms. As climates change, the distributions of these organisms change along with their associated parasites, mutualists and commensals. Less studied, however, is the possibility that environmental conditions may directly influence …

Influence of Grooming on Permanent Arthropod Associates of Birds: Cattle Egrets, Lice, and Mites

Matthew M. Waller, Hannah M. Warr, Graham B. Goodman, Sarah E. Bush et autres

Birds have a diverse community of "permanent" arthropods that complete their entire life cycle on the body of the host. Because some of these arthropods are parasites that reduce host fitness, birds control them by grooming, which consists of preening with the …

A Gaussian process guide for signal regression in magnetic fusion

Craig Michoski, Todd Oliver, David R. Hatch, Abdoulaye Billo Diallo et autres

Abstract Extracting reliable information from diagnostic data in tokamaks is critical for understanding, analyzing, and controlling the behavior of fusion plasmas and validating models describing that behavior. Recent interest within the fusion community has focused on the use of principled statistical methods, …
