Many coral diseases are characterized based on gross descriptions and, given the lack or difficulty of applying existing laboratory tools to understanding causes of coral diseases, most new diseases will continued to be described based on appearance in the field. Unfortunately, many existing descriptions of coral disease are ambiguous or open to subjective interpretation, making...

If you are interested in lichens and National Parks, now you can query a lichen database that combines these two elements. Using pull-down menus you can: search by park, specifying either species list or the references used for that area; search by species (a report will show the parks in which species are found); and search by reference codes, which are available from the first query...

The study of coral disease has suffered from an absence of systematic approaches that are commonly used to determine causes of diseases in animals. There is a critical need to develop a standardized and portable nomenclature for coral lesions in the field and to incorporate more commonly available biomedical tools in coral disease surveys to determine the potential causes of lesions in...

Oriental white-backed vultures (Gyps bengalensis; OWBVs) died of renal failure when they ingested diclofenac, a nonsteroidal anti-inflammatory drug (NSAID), in tissues of domestic livestock. Acute necrosis of proximal convoluted tubules in these vultures was severe. Glomeruli, distal convoluted tubules, and collecting tubules were relatively spared in the vultures that had early lesions...

A number of factors were identified as causes of mortality in 254 (59%) of 431 sea ducks submitted for necropsy at the USGS-National Wildlife Health Center, Madison, Wisconsin from 1975 until 2003. Bacteria causing large outbreaks of mortality were Pasteurella multocida and Clostridium botulinum Type E. Starvation was responsible for large mortality events as well as sporadic deaths of...

Wildlife veterinarians and rehabilitators treat a number of wildlife species that can carry infectious and zoonotic diseases. These can rapidly spread within a facility and to the caregivers when adequate measures are not taken. Financial constraints and reduced access to laboratories often limit identification of disease etiology of many cases admitted into wildlife rehabilitation...

Introduced avian pox virus and malaria have had devastating impacts on native Hawaiian forest birds, yet little has been published about their prevalence and distribution in forest bird communities outside of windward Hawaii Island. We surveyed native and non-native forest birds for these two diseases at three different elevations on leeward Mauna Loa Volcano at the Kona Forest Unit of...

This chapter is devoted to the diseases of anuran larvae that cause morbidity( illness) and mortality (death). The purpose of this chapter is to describe diseases that may be encountered in free-living tadpoles of the United States and Canada. Much of the information in this chapter comes from unpublished diagnostic examinations of amphibians done at the U.S. Geological Survey, National...

Few diseases are reported in salamanders. Two notable exceptions are infections by Ranavirus and Ichthyophonus. Except for mortality events associated with ranaviruses in tiger salamanders (Ambystoma tigrinum) and spotted salamanders (A. maculatum), dieoffs of salamanders are rarely detected or reported. Diseases presented in this chapter are those encountered in free-living salamanders...

The Point Reyes peninsula in northern California is about 45 km northwest of San Francisco and occasionally receives air masses from the city contributing to haze and lowered visibility. Although gaseous pollutants are not a problem, fine particulates containing carbon and other elements are measurable at the park. In this study, five lichen species were sampled along a 40-km linear...
