    A Checklist of Host-Parasite Interactions of the Order Crocodylia
    Book Description:

    Records of parasitism in crocodilians date back to the early 1800s, distributed among various types of published and unpublished materials. Analyzing parasite-host specificity, geographic distribution, and taxonomy can provide otherwise cryptic details about crocodilian ecology and evolution, as well as their local food web dynamics. This information is critical for improved conservation tactics for both crocodilians and their habitat.

    As climate change, anthropogenic conflict, and environmental pollution endanger crocodilian ecosystems, there is a need for organized information on crocodile, alligator, caiman, and gharial infectious diseases. This volume meets this need by delivering the first checklist of crocodilians and their parasites for researchers and scholars in biology, herpetology, and ecology in order to further the knowledge and study of crocodilian-parasite dynamics and improve our understanding of human impacts on ecosystems.

    The order Crocodylia comprises of an archaic lineage of reptiles descended from an archosaurian ancestor that lived about 254 million years ago (Janke and Arnason, 1997). Behavioral, morphological and physiological adaptations such as parental care, a four-chambered heart, and osmoregulation capabilities are crocodilian characteristics that distinguish them from other reptilians (Shine, 1988; Mazzotti and Dunson, 1989; Franklin and Axelsson, 1994). The immediate and non-hesitant immune system of crocodilians, in comparison to other vertebrates, is an exceptional evolutionary adaptation in response to wounds from intra- and interspecific conflict in bacteria-laden environments (Merchant et al., 2003, 2004, 2005). This suite of adaptations...

    Records of parasites in crocodilians date to the early 1800s. Sources of information on crocodilian parasites are widely scattered and often published in inaccessible journals. Previously published checklists of vertebrate or reptilian parasites have included crocodilians, however many did not include all crocodilian species, nor all crocodilian parasite species reported (York and Maplestone, 1926; Dubois, 1936b, 1938b; Schuurmans-Stekhoven, 1937; Hughes et al., 1941b,c, 1942; Skrjabin, 1951a,b,c, 1964; Yamaguti, 1954, 1958, 1971, 1975; Dubois, 1969; Lauckner, 1985; Baker, 1987; Thatcher, 1993; Huchzermeyer, 2003). For example, Lauckner (1985) in the Diseases of Marine Mammals edited by Kinne overlooked listing the parasites of...

    Crocodilians are large, long-lived apex predators. As top predators, they also may accumulate various trophically transmitted parasites by consuming a wide variety of prey hosts over a long period of time. These life-history traits enable them to acquire and accumulate various parasite species over many years. In general, crocodilians are parasitized by a diverse array of species (Table 1). Caiman crocodilus crocodilus has the greatest reported species richness of parasites (~49 species), followed by Crocodylus porosus (~36 species), C. niloticus (~36 species), and Alligator mississippiensis (~26 species) (Table 3). Both C. c. crocodilus and C. porosus are frequently studied species...

    This crocodilian-parasite database provides a foundation for future research on crocodilian parasitism. Data extrapolated from this study can be utilized to investigate the role of crocodilian parasites in food webs, and ecosystems, and how stressors may alter host-parasite dynamics. Studies have linked predator reduction to reduced presence of trophically transmitted parasites, and concomitant increase in other types of parasites of abundant hosts at lower trophic levels (Lafferty and Kuris, 1999; Bush et al., 2001; Lafferty et al., 2008). Moreover, the fundamental dependence of parasites on both host and environment supports the use of parasites as biological indicators of environmental conditions....

    Since the final edit was accepted, another report of crocodile parasitism has been published, as well as a study of the genetic divergence of Osteolaemus in different regions in Africa.

    A nematode parasite was discovered in the Nile crocodile (La Grange et al., 2013). Its placement is described under the crocodile-parasite section below, omitting the already documented data within the monograph. The reference is included after the description....
