The effects of parasites on host behavior : who benefits?

Creator:: Lefcort, Hugh G.
Abstract:: Some parasites may modify the behavior of their hosts. Altered behaviors may: 1) benefit the host in that they defend against the pathogen, 2) benefit the pathogen and represent manipulations of the host response, and 3) benefit neither the host or the pathogen and simply be a product of the...

Kin recognition in Townsend's chipmunks (Tamias townsendii)

Creator:: Fuller, Claire A.
Abstract:: Juvenile T. townsendii were tested at 55-62 days of age to determine whether 1) they could distinguish kin from non-kin and 2) whether this ability was based on familiarity or on genetic relatedness. Seventy-three pups were observed in 68 pairwise tests. The frequencies and durations of 8 behaviors as well...

Unpalatability as an antipredator defense in anuran larvae

Creator:: Peterson, Jeffrey A.
Abstract:: The tadpoles of several anuran species with groupforming larvae are relatively unpalatable to many of their potential predators. To more fully understand the role of palatability and its relationship to group formation as an antipredator defense in anuran amphibian larvae, I investigated the palatabilities of the larvae of three species...

The Effects of Nitrate and a Pathogenic Fungus, Batrachochytrium dendrobatidis, on Amphibians

Creator:: Negru, Delia
Abstract:: The current rate of global biodiversity loss and extinctions is unparalleled and a major concern. Freshwater organisms are facing particularly rapid rates of biodiversity loss. Amphibians, which require an aquatic environment for part of their life cycle, are one of the most vulnerable vertebrate groups. Amphibians are experiencing population declines,...

The Role of Emerging Pathogens in Amphibian Population Declines : Experimental Evidence

Creator:: Hambalek, Natalie M.
Abstract:: Rapid rates of biodiversity loss have supported the notion that Earth is experiencing a sixth major extinction event. The causes of worldwide biodiversity loss are multifaceted and context dependent. One of the most prominent groups experiencing population declines and extinctions are amphibians. Several pathogens and their associated diseases are especially...

The effects of multiple pathogens on amphibians in the Pacific Northwest

Creator:: Romansic, John M.
Abstract:: The earth is undergoing a “biodiversity crisis” characterized by loss of populations, species, genetic diversity, and ecosystem services. Part of this crisis consists of population declines, extinctions, and increased incidence of deformities in amphibians. It is unknown whether deformities contribute to these declines. Many cases of population declines in amphibians...

Indirect effects of ultraviolet-B radiation on larval amphibians as mediated by food quality and trophic interactions

Creator:: Scheessele, Erin A.
Abstract:: Ultraviolet-B radiation (UVB) is an abiotic stressor in both terrestrial and aquatic systems. The stratospheric ozone layer, depleted due to anthropogenic activities and the cause of elevated UVB at earth's surface over the last four decades, is predicted to recover by 2065. However, UVB levels in aquatic systems may continue...

Complexity in host-pathogen dynamics : dispersal uncertainties, metapopulation persistence and the role of a changing climate

Creator:: Xie, Yang
Abstract:: Emerging infectious diseases impact both human and wildlife populations. Infectious agents, in particular the aquatic fungus Batrachochytrium dendrobatidis (chytrid), have an influential role in driving global amphibian population declines. The emergence of the chytrid fungus has aspects of both geographic spread as well as climate shifts altering environmental conditions and...
