Piscichuvirus-Associated Severe Meningoencephalomyelitis in Aquatic Turtles, United States, 2009–2021

Weerapong Laovechprasit, Kelsey T. Young, Brian A. Stacy, Steven B. Tillis et autres

Viruses from a new species of piscichuvirus were strongly associated with severe lymphocytic meningoencephalomyelitis in several free-ranging aquatic turtles from 3 coastal US states during 2009-2021. Sequencing identified 2 variants (freshwater turtle neural virus 1 [FTuNV1] and sea turtle neural virus 1 …

Successful Eradication of Signal Crayfish (Pacifastacus leniusculus) Using a Non-Specific Biocide in a Small Isolated Water Body in Scotland

Liza Ballantyne, David H. Baum, Colin W. Bean, Jo Long et autres

The North American signal crayfish (Pacifastacus leniusculus) has been present in Scotland since at least 1995 and the species is now known to be present in a number of catchments. Once established, few opportunities for containment exist and eradication can often be …

Avian cell-mediated immune response to drought

Jeanne Marie Fair, Shayna Whitaker

Regional droughts have far-reaching, substantial, and easily recognizable impacts on populations and the environment. One component of these impacts that is not widely recognized is impairment of immune function by drought-related physiological stress. We studied cell-mediated immune function of cavity-nestling Western Bluebirds …

Sources of variation in haematocrit in birds

Jeanne Marie Fair, Shayna Whitaker, Brandon L. Pearson

The validity of the haematocrit or packed cell volume as an indicator of condition in wild birds has recently been questioned. We reviewed over 300 published papers on haematocrit values for wild birds. These studies show that changes in haematocrit could be …

The costs of immunological challenge to developing mountain chickadees, Poecile gambeli, in the wild

Shayna Whitaker, Jeanne Marie Fair

The tradeoff between immunocompetence and development in avian species could have long‐term consequences relating to fitness. This study investigated the developmental cost of mounting a humoral immune response in growing mountain chickadees, Poecile gambeli . We immunologically challenged nestling chickadees using nonpathogenic …
