Brain Experiment Using Salamanders: The Spemann-Mangold Experiments German scientist Hans Spemann and Ph d candidate Hilde Mangold take the proverbial cake for strange brain experiments.
In their momentous study, the brain of a live salamander was extracted and divided into sections.
The remainder as dropped back into the still-living salamander body and the salamander would jump up
Spemann and Mangold would also conduct studies involving splitting salamander embryos in two and injecting parts of one half into the other just to see what would happen. http://ts-si. org/biology/3305-brain-before-body-the-spemann-mangold-experiments 12.

#Road Runoff Spurring Spotted salamander Evolution A female spotted salamander gravid with eggs in route to her breeding pool.
Spotted salamanders exposed to contaminated roadside ponds are adapting to their toxic environments, according to a Yale paper in Scientific Reports.
This study provides the first documented evidence that a vertebrate has adapted to the negative effects of roads apparently by evolving rapidly Salamanders breeding in roadside ponds are exposed to a host of contaminants from road runoff.
#Brady found that salamanders in roadside ponds have higher mortality, grow at a slower rate
In roadside ponds, only 56 percent of salamander eggs survive the first 10 weeks of development,
the surviving salamanders may develop a genetic advantage over their counterparts living in woodland ponds.
The salamanders that survive year after year in the roadside ponds appear to have adapted to the harsh conditions.
salamanders are just bystanders to human activities. This suggests that the majority of species, which are targeted not specifically for human use,

#Woodland salamanders indicators of forest ecosystem recoverywoodland salamanders are a viable indicator of forest ecosystem recovery according to researchers from the U s. Forest Service's Pacific Southwest Research Station.
PSW Research Wildlife Biologist Dr. Hartwell Welsh and Garth Hodgson examined two species of woodland salamanders across four stages of tree development at Mill Creek--a disturbed
and body condition of two common species of salamander tracked closely with forest stand growth development and structural changes.
Using salamander population numbers and physiological condition on adjacent never harvested old-growth parkland to reference advancements along this developmental pathway they demonstrated relationships between salamander counts
and body condition and aspects of forest advancement including stand age tree size ambient moisture canopy closure
when woodland salamanders are found in high abundance it indicates a healthy forest having undergone ecological advancement and ecosystem recovery.
The woodland salamanders evaluated in Mill Creek were deemed credible due to their conservatism trophic role and high site fidelity which tie them closely to conditions of place.
and blue-spotted salamanders explained Sacerdote-Velat. Several amphibian species exhibit low hatching rates in sites that are infested heavily with European buckthorn.
tree salamanders have same dietssalamanders spend the vast majority of their lives below ground and surface only for short periods of time and usually only on wet nights.
When they do emerge salamanders can be spotted not only on forest floors but also up in trees and on other vegetation oftentimes climbing as high as 8 feet up.
Given their infrequent appearances aboveground it has never been clear to biologists why salamanders take time to climb vegetation.
Researchers at the University of Missouri recently conducted a study testing a longstanding hypothesis that salamanders might climb vegetation for food.
Previous research suggested that plant climbing might be a way for salamanders to access additional prey items like aphids
Connette and his colleagues tested the hypothesis by collecting red-legged salamanders (Plethodon sharmani) and examining their stomach contents.
The researchers captured an equal number of salamanders on the ground and up on trees or shrubs and then brought them back to the lab where they anesthetized them
The salamanders--minus their last meals--were returned then safely to their exact capture location. The stomach contents were preserved in alcohol
At the end they had a laundry list of things found in the guts of these salamanders.
What was surprising was that the salamanders collected on trees did not have anything one would associate with a plant-feeding insect like aphids.
The diet of the salamanders captured on the ground was the same as the diet of salamanders captured sitting high up on vegetation.
We found no evidence that climbing allows these salamanders to more fully exploit available food resources
or predator avoidance might be important influences on salamander populations said Connette. The study was prompted by the research of Curators'Professor Ray Semlitsch who has been studying salamander populations in the Appalachian mountains since 2005.
The mountain range's moist forests make it a global hot spot for a variety of salamander species. Connette said that by testing a possible explanation for climbing behavior the research also provides important background information about how salamanders can exist in high densities
in North american forests. The study Relationship between diet and microhabitat use of red-legged salamanders (Plethodon shermani) in southwestern North carolina appeared in the journal Copeia.

#Predation on invertebrates by woodland salamanders increases carbon capturewoodland salamanders perform a vital ecological service in American forests by helping to mitigate the impacts of global warming.
Woodland salamanders facilitate the capture of this carbon before it is released by feeding on invertebrates (beetles earthworms snails ants etc.
and other forest debris. Woodland salamanders are the most common vertebrate species in American forests;
Dr. Hartwell Welsh Jr. research wildlife biologist at the U s. Forest Service's Pacific Southwest Research Station (PSW) helped conduct a study in Northwestern Calif. that examined how woodland salamander
The objective of the study was to investigate the role of salamanders in regulating invertebrate abundances
The study included soil moisture as a covariate and field enclosures on the forest floor to quantify the effects of woodland salamanders.
and found that woodland salamander predation on invertebrates suppressed some populations of invertebrates and released others with the overall result of increased litter retention and carbon capture in the soil.
and raise awareness of the ecological role woodland salamanders play in the forest carbon cycle. The renowned evolutionary biologist E. O. Wilson once said it is the little things that run the world Dr. Welsh said.
#Salamanders help predict health of forest ecosystems, inform forest managementwoodland salamanders are small lungless amphibians that live in moist forest habitats throughout the U s. and the world.
Salamanders often serve as vital links in forest food chains; their population size and recovery from major disturbances can help predict the health of forest ecosystems.
Now researchers at the University of Missouri have determined that salamander population size reflects forest habitat quality
and can predict how ecosystems recover from forest logging activity. MU researchers believe these findings can be translated to other species within forest ecosystems throughout the world.
We also determined that salamander recovery --or the amount of time it takes for salamanders to repopulate a cut forest area--can help forest managers determine appropriate logging schedules.
Semlitsch and fellow researcher Grant Connette a graduate student in the Division of Biological sciences chose to study a forest area in the southern Appalachian mountains that has the highest diversity of salamanders in the world.
Although seldom seen in the daytime these animals breathe using their wet skin and forage at night.
The researchers conducted surveys of terrestrial salamanders which don't rely on water or streams to examine patterns of their abundance relative to timber harvest and species movement behavior.
They discovered that forests logged more than 100 years ago may still be affecting salamanders today.
Their research Life history as a predictor of salamander recovery rate from timber harvest in southern Appalachian forests U s a. was published in Conservation Biology.
