To examine the extent to which aquatic prey-capture behavior in salamanders is stereotyped and how feeding kinematics scales with size, the ontogenetic variability of aquatic feeding behavior was examined in eight Salamandra salamandra. Feeding kinematics (seven duration and angular displacement variables), kinematic variance and capture performance were quantified and compared in the first several feedings after birth with a series of feedings 8 weeks later, just prior to metamorphosis. Analysis of variance revealed no statistically significant ontogenetic differences in the kinematic variables, and individual differences were found in only two variables (maximum gape angle and gape cycle time). A comparison of the relative kinematic variance within individuals revealed no significant differences in variance during ontogeny. In addition, capture success rate did not change. The strike is significantly faster than that of other salamanders. These results indicate that the initial prey-capture ...
Nine salamander hearts have been studied histologically by means of serial sections, cut in each of three planes (transverse, frontal and sagittal), and stained with haemalum and eosin, van Giesons acid fuchsin and iron-haematoxylin, and by the protargol method of Bodian. I his study has demonstrated muscular continuity between the several cardiac chambers, and the entile absence of any specialized muscle or nodal tissue at the junctional sites or in any other part of the heart. The heart muscle forms a continuum. The cardiac muscle fibres are characterized by their large size (i.e. breadth); they have the same general histological characters in all parts of the heart. Measurements are given for the fibres from various parts of the hearts of the salamander and frog. The muscular connexions between the various cardiac chambers have been studied in detail. In each of the chambers the musculature is arranged in a basket-work fashion, but at each of the junctional sites the muscle suddenly ...

Fire salamanders (Salamandra salamandra) and an earthworm, close-up. Fire salamanders are found in forested and hilly areas across continental Europe, living in leaf litter. Like other amphibians, they need streams or ponds in which to lay eggs. They are largely nocturnal, hunting at night for worms, insects and slugs. Their striking yellow and black colouration warns potential predators that they are highly toxic. - Stock Video Clip K003/1929
ABSTRACT: Highly virulent pathogens that cause host population declines confront the risk of fade-out, but if pathogen transmission dynamics are age-structured, pathogens can persist. Among other features of amphibian biology, variable larval developmental rates generate age-structured larval populations, which in theory can facilitate pathogen persistence. We investigated this possibility empirically in a population of Salamandra salamandra in Spain affected by Batrachochytrium dendrobatidis (Bd) at breeding sites that lacked alternative amphibian hosts. None of the adults presented infection by Bd. However, for the larvae, while environmental heterogeneity was the most important predictor of infection, the effect on infection dynamics was mediated by transmission from overwintered larvae to new larval recruits, which occurred only in permanent larval habitats. We suggest that interannual Bd maintenance in a host population that experiences mass mortality associated with infection can occur ...
The effect of past climatic changes on the distribution of organisms is a fertile field of research that has been tackled in many different ways. Because the fossil record provides direct access to the chronological and geographic dimensions of biological events occurred in the past, it can be a useful tool for assessing range contractions and expansions related to climatic changes. Here, we provide support for the recent shrinkage of the range of a frigophilous anuran, the common frog, Rana temporaria Linnaeus, 1758, by analyzing the amphibian fossil assemblage coming from the Grotta di Equi, a Late Pleistocene site (about 45 ka) located in the Apuan Alps (northern Apennine chain, Massa-Carrara Province, Italy). Besides, R. temporaria, the assemblage includes cf. Salamandra salamandra Linnaeus, 1758 and Bufo bufo Linnaeus, 1758. The presence of R. temporaria in the Apuan Alps during a cold interglacial phase at an elevation that is much lower than the minimum current elevation in the region (about

Approximately 55 extant species in 15 genera are recognized in this morphologically and behaviorally diverse family of salamanders. Geographic distribution is the largest of any salamander family, with four disjunct centers. Salamandrids occur primarily in Europe (throughout most of Europe, South into northern Africa and east into Asia), and Asia (especially India, Southern China, and mainland Southeast Asia). Two genera are endemic to North America.. The salamandrids are informally subdivided into two subgroups, the "true salamanders" (including the genera Chioglossa, Mertensiella, and Salamandra), and the newts (the remaining genera). The "true salamanders" tend to be smooth skinned, while the newts are unlike all other salamanders in having rough skin that is not slimy.. Most adult salamandrids are small, rarely exceeding 20 cm in length, and brightly colored. All salamandrids have toxic skin secretions (some produce tetrodotoxins), and many have bright warning coloration that is used in ...

The terse reply could be said to be a clear rejection but when it came to Maxwell, this would only be seen as her way of hiding her embarrassment. Maxwell did not display any sign of taking offense as he moved his face closer to try kiss the blue hair within his grasp. Yō who had been stumped by the exchanges of the two before her had then returned to her senses and she recognized the danger in the situation. "You, You Stalker!" Whipping up a shimmering whirlwind, Yō made a straight charge towards Maxwells chest. Although he had already been prepared for counter attacks from the enemies, Maxwell, who was infatuated by Willa, was still sent flying into the passageways of the Palace by a kick that sank deeply into the back of his waist. Similarly, the stationed troops from [Salamandra], who were surprised audience not too long ago, had launched their pursuit and subsequent attacks. "Now. Use this time! Lets attack as one!" Under the shouted command, the Lesser Dragons who wielded spears and ...

Organisers: Frank Pasmans (Ghent University), Matthew Gray (University of Tennessee), An Martel (Ghent University), Molly Bletz (University of Massachusetts-Boston and Amphibian Survival Alliance), Andrew Cunningham (Zoological Society of London), and Debra Miller (University of Tennessee and Wildlife Disease Association). Outline: Batrachochytrium salamandrivorans (Bsal) is a recently discovered fungal pathogen that causes a necrotizing skin disease in susceptible amphibian species and is currently emerging on the European continent. Bsal is believed to be from Asia and was probably introduced to Europe through international trade of amphibians. Its presence on other continents remains unknown but several nations have begun surveillance programs due to Bsals potential to devastate amphibian biodiversity. Initial susceptibility trials suggest that over two-thirds of North American salamander species are susceptible to infection and about one-third have low infection tolerance and develop the ...

Session presented on Friday, July 25, 2014: Background and Purpose: An organization faces many challenges when building a new healthcare facility and preparing to move or expand into this facility. Strategies to plan and implement such a move have been described in the literature. Guzman, Nering, and Salamandra (2008) outline the use of specific project management tools and the application of the nursing process (assess, plan, implement, and evaluate) in organizational transition planning. The scope of a successful transition plan must address the roles and responsibilities of organizational members, licensing and regulatory requirements, a transition budget, move planning, and management of change related to transition (Guzman et al., 2008). Since the physical transition to the new facility is at the heart of a move or expansion project, other authors focus on specific guidelines for occupancy or activation planning. According to Wilson, Hejna, and Hosking (2004), Activation planning involves ...
We tested whether the sex pheromones that stimulate courtship clasping in male roughskin newts do so, at least in part, by amplifying the somatosensory signals that directly trigger the motor pattern associated with clasping and, if so, whether that amplification is dependent on endogenous vasotocin (VT). Female olfactory stimuli increased the number of action potentials recorded in the medulla of males in response to tactile stimulation of the cloaca, which triggers the clasp motor reflex, as well as to tactile stimulation of the snout and hindlimb. That enhancement was blocked by exposing the medulla to a V1a receptor antagonist before pheromone exposure. However, the antagonist did not affect medullary responses to tactile stimuli in the absence of pheromone exposure, suggesting that pheromones amplify somatosensory signals by inducing endogenous VT release. The ability of VT to couple sensory systems together in response to social stimulation could allow this peptide to induce variable behavioural

I got a tip that there were tiger salamanders with gills swimming around below Los Alamos reservoir, so I had to go see for myself. Theyre fabulous! Four to five inch salamanders with flattened tails and huge frilly gills behind their heads -- dozens of them, so many the pond is thick with them. Plenty of them are hanging out in the shallows or just below the surface of the water, obligingly posing for photos. I had stupidly brought only the pocket camera, not the DSLR -- and then the cameras battery turned out to be low -- so I was sparing with camera, but even so I was pleased at how well they came out, with the camera mostly managing to focus on the salamanders rather than (as I had feared) the surface of the murky water. I may go back soon with the DSLR. Its an easy, pleasant hike. Photos: Tiger Salamander larvae ...

In 1893, Julia Barlow Platt published her research on the origins of cartilage in the developing head of the common mudpuppy (Necturus maculosus) embryo. The mudpuppy is an aquatic salamander commonly used by embryologists because its large embryonic cells and nuclei are easy to see. Platt followed the paths of cells in developing mudpuppy embryos to see how embryonic cells migrated during the formation of the head. With her research, Platt challenged then current theories about germ layers, the types of cells in an early embryo that develop into adult cells..
