  • What Do Tadpoles Really Eat? Assessing the Trophic Status of an Understudied and Imperiled Group of Consumers in Freshwater Habitats
    Freshwater Biology (2007) 52, 386–395 doi:10.1111/j.1365-2427.2006.01694.x OPINION What do tadpoles really eat? Assessing the trophic status of an understudied and imperiled group of consumers in freshwater habitats RONALD ALTIG,* MATT R. WHILES† AND CINDY L. TAYLOR‡ *Department of Biological Sciences, Mississippi State University, Mississippi State, MS, U.S.A. †Department of Zoology and Center for Ecology, Southern Illinois University, Carbondale, IL, U.S.A. ‡Department of Biology, Austin Peay State University, Clarksville, TN, U.S.A. SUMMARY 1. Understanding the trophic status of consumers in freshwater habitats is central to understanding their ecological roles and significance. Tadpoles are a diverse and abundant component of many freshwater habitats, yet we know relatively little about their feeding ecology and true trophic status compared with many other consumer groups. While many tadpole species are labelled herbivores or detritivores, there is surprisingly little evidence to support these trophic assignments. 2. Here we discuss shortcomings in our knowledge of the feeding ecology and trophic status of tadpoles and provide suggestions and examples of how we can more accurately quantify their trophic status and ecological significance. 3. Given the catastrophic amphibian declines that are ongoing in many regions of the planet, there is a sense of urgency regarding this information. Understanding the varied ecological roles of tadpoles will allow for more effective conservation of remaining populations, benefit captive breeding programmes, and allow for more accurate predic- tions of the ecological consequences of their losses. Keywords: amphibian, assimilation, diet, feeding behaviour, omnivory Amphibians are disappearing from the planet at an of the functional roles and trophic status of general- alarming rate (Stuart et al., 2004; Lips et al., 2005).

    Pseudoeurycea naucampatepetl. The Cofre de Perote salamander is endemic to the Sierra Madre Oriental of eastern Mexico. This relatively large salamander (reported to attain a total length of 150 mm) is recorded only from, “a narrow ridge extending east from Cofre de Perote and terminating [on] a small peak (Cerro Volcancillo) at the type locality,” in central Veracruz, at elevations from 2,500 to 3,000 m (Amphibian Species of the World website). Pseudoeurycea naucampatepetl has been assigned to the P. bellii complex of the P. bellii group (Raffaëlli 2007) and is considered most closely related to P. gigantea, a species endemic to the La specimens and has not been seen for 20 years, despite thorough surveys in 2003 and 2004 (EDGE; www.edgeofexistence.org), and thus it might be extinct. The habitat at the type locality (pine-oak forest with abundant bunch grass) lies within Lower Montane Wet Forest (Wilson and Johnson 2010; IUCN Red List website [accessed 21 April 2013]). The known specimens were “found beneath the surface of roadside banks” (www.edgeofexistence.org) along the road to Las Lajas Microwave Station, 15 kilometers (by road) south of Highway 140 from Las Vigas, Veracruz (Amphibian Species of the World website). This species is terrestrial and presumed to reproduce by direct development. Pseudoeurycea naucampatepetl is placed as number 89 in the top 100 Evolutionarily Distinct and Globally Endangered amphib- ians (EDGE; www.edgeofexistence.org). We calculated this animal’s EVS as 17, which is in the middle of the high vulnerability category (see text for explanation), and its IUCN status has been assessed as Critically Endangered.

  • Functional Morphology and Evolution of Tail Autotomy in Salamanders
    Functional Morphology and Evolution of Tail Autotomy in Salamanders DAVID B. WAKE AND IAN G. DRESNER Department of Anatomy, The University of Chicago, Chicago, lllinois ABSTRACT Basal tail constriction occurs in about two-thirds of the species of plethodontid salamanders. The constriction, which marks the site of tail autotomy, is a result of a reduction in length and diameter of the first caudal segment. Gross and microscopic anatomical studies reveal that many structural specializations are associated with basal constriction, and these are considered in detail. Areas of weak- ness in the skin at the posterior end of the first caudal segment, at the attachment of the musculature to the intermyotomal septum at the anterior end of the same segment, and between the last caudosacral and first caudal vertebrae precisely define the route of tail breakage. During autotomy the entire tail is shed, and a cylinder of skin one segment long closes over the wound at the end of the body. It is suggested that specializations described in this paper have evolved jndepend- ently in three different groups of salamanders. Experiments and field observations reveal that, contrary to expectations, frequency of tail breakage is less in species with apparent provisions for tail autotomy than in less specialized species. The tail is a very important, highly functional organ in salamanders and it is suggested that selection has been for behavioral and structural adaptations for control of tail loss, rather than for tail loss per se. Tail loss and subsequent regeneration is sent facts concerning anatomical details a well documented phenomenon among of the basal tail region, a functional inter- the lower vertebrates.
