However, what often goes unnoticed are the declines of smaller, cryptic, and less well-known species.<\/p>\n<p>In fact,<strong> amphibians are one of the most threatened taxa with 25% of species (~2000 species) being at risk of extinction<\/strong> and another 25% being data deficient or without evaluation by the International Union of Conservation of Nature (IUCN). This is obviously concerning, especially considering amphibians are often overlooked by researchers and in conservation. Our lack of knowledge on amphibians prevents us from understanding how this imperiled group of animals will respond to global change, including alterations to the environment that stem from human activities.<\/p>\n<p>The eastern red-backed salamander (<em>Plethodon cinereus<\/em>) is a small (5-13 cm) terrestrial salamander species commonly found across eastern North America. These little creatures get their name from the distinctive red stripe that runs along their back, although there are a variety of colour morphs that do not sport this stripe including the lead-back (no stripe), erythristic (entirely or mostly bright red or orange), and leucistic (reduced colouration) morphs. Eastern red-backed salamanders are part of the lungless salamander family Plethodontidae, which means they breathe only through their skin. This trait also makes them particularly sensitive to changes in their environment and makes them a great indicator species of forest health.<\/p>\n<\/div><\/section><br \/>\n\n<style type=\"text\/css\" data-created_by=\"avia_inline_auto\" id=\"style-css-av-lxuqpiys-2e88681efa44c9959463a710b9515b3d\">\n.avia-image-container.av-lxuqpiys-2e88681efa44c9959463a710b9515b3d img.avia_image{\nbox-shadow:none;\n}\n.avia-image-container.av-lxuqpiys-2e88681efa44c9959463a710b9515b3d .av-image-caption-overlay-center{\ncolor:#ffffff;\n}\n<\/style>\n<div  class='avia-image-container av-lxuqpiys-2e88681efa44c9959463a710b9515b3d av-styling- avia-align-center  avia-builder-el-8  el_after_av_textblock  avia-builder-el-last'   itemprop=\"image\" itemscope=\"itemscope\" itemtype=\"https:\/\/schema.org\/ImageObject\" ><div class=\"avia-image-container-inner\"><div class=\"avia-image-overlay-wrap\"><img class='wp-image-47175 avia-img-lazy-loading-not-47175 avia_image' src='https:\/\/wildlifepreservation.ca\/wp-content\/uploads\/2024\/06\/Thermal-Gradient.png' alt='' title='Thermal Gradient'  height=\"491\" width=\"1167\"  itemprop=\"thumbnailUrl\"  \/><\/div><\/div><\/div><\/p><\/div><div  class='flex_column av-rfikch-3810b8e2a3b2224842cc8a250d40d4a6 av_one_full  avia-builder-el-9  el_after_av_one_full  el_before_av_textblock  light-section first flex_column_div  column-top-margin'     ><p><section  class='av_textblock_section av-lxuqrucq-5ed8ab0abffc18db86b44296e548f785'   itemscope=\"itemscope\" itemtype=\"https:\/\/schema.org\/BlogPosting\" itemprop=\"blogPost\" ><div class='avia_textblock'  itemprop=\"text\" ><p><em>Thermal gradient schematic.

The gradient will be created using warm and cold water that will transfer their temperatures to the copper base through the copper piping fused to the bottom of the gradient on either side. Schematic by Joshua Christiansen.<\/em><\/p>\n<p>Les pluviers siffleurs <a href=\"https:\/\/www.rileyecology.com\/\">Riley Integrative Ecology Lab<\/a> at Mount Allison University in Sackville, New Brunswick is currently exploring the thermal ecophysiology of urban and natural populations of eastern red-backed salamanders (<em>Plethodon cinereus) to<\/em> study whether the environmental changes associated with urbanization are changing forest ecosystems and the wildlife within them in Atlantic Canada. In particular, urbanization can cause the urban \u2018heat island\u2019 effect where ambient, soil, and water temperatures increase due to increases in paved surface areas and reduced vegetation and water surfaces that are characteristic of urban areas.<\/p>\n<p>For our research, a total of 72 salamanders were collected from three urban and three natural sites and are being temporarily housed in a temperature- and humidity-controlled lab space at Mount Allison University. To assess the thermal preferences of these salamanders, researchers have built an annular (or donut shaped) enclosure with a temperature gradient along the bottom that will allow salamanders to explore the thermal environment and select the temperature they most prefer. The researchers are aiming to determine whether urban and natural salamanders prefer different temperatures, perhaps as a result of the urban heat island effect, or if there are no differences in their thermal preferences. Understanding how these salamanders react to different temperatures can reveal whether Atlantic Canada amphibians have the capacity to adapt to climate change and urbanization or if increases in temperature and urbanization may threaten the persistence of these animals in our changing world.<\/p>\n<p>At the end of the experiment, the salamanders will be released at their original capture locations, and they might just tell all their salamander friends that they were simply on vacation for a while!<\/p>\n<h5><em>WPC is supporting this research by providing salary support for Jaden Sellen, a field and lab technician in the Riley Integrative Ecology Lab.<\/em><\/h5>\n<\/div><\/section><br \/>\n\n<style type=\"text\/css\" data-created_by=\"avia_inline_auto\" id=\"style-css-av-lxuqscrb-c760cdea49ccf84f830247ca80e8124b\">\n.avia-image-container.av-lxuqscrb-c760cdea49ccf84f830247ca80e8124b img.avia_image{\nbox-shadow:none;\n}\n.avia-image-container.av-lxuqscrb-c760cdea49ccf84f830247ca80e8124b .av-image-caption-overlay-center{\ncolor:#ffffff;\n}\n<\/style>\n<div  class='avia-image-container av-lxuqscrb-c760cdea49ccf84f830247ca80e8124b av-styling- avia-align-center  avia-builder-el-11  el_after_av_textblock  avia-builder-el-last'   itemprop=\"image\" itemscope=\"itemscope\" itemtype=\"https:\/\/schema.org\/ImageObject\" ><div class=\"avia-image-container-inner\"><div class=\"avia-image-overlay-wrap\"><img class='wp-image-47174 avia-img-lazy-loading-not-47174 avia_image' src='https:\/\/wildlifepreservation.ca\/wp-content\/uploads\/2024\/06\/20240612_EasternRed-backedSalamander_Joshua-Christiansen_FromCSJBlog-1620x1080.jpg' alt='' title='20240612_EasternRed-backedSalamander_Joshua Christiansen_FromCSJBlog'  height=\"1000\" width=\"1500\"  itemprop=\"thumbnailUrl\"  \/><\/div><\/div><\/div><\/p><\/div><section  class='av_textblock_section av-lxutoi54-551f77a09871f22dec02768a8ae65a7b'   itemscope=\"itemscope\" itemtype=\"https:\/\/schema.org\/BlogPosting\" itemprop=\"blogPost\" ><div class='avia_textblock'  itemprop=\"text\" ><p><em>Eastern red-backed salamander.
