The Relationship Between Forest Type and Amphibian Abundance

Follow the twitter account @nofibs4amphibs to learn more and see fun updates on the research project! Introduction Amphibians are cold-blooded vertebrates who undergo fascinating metamorphoses. Once upon a time, they were the top land predators from the Carboniferous to early Permian (Carroll 2009). A diverse group, they occupy many niches and play an invaluable role […]

Variation of the Refuge Depth of Salamanders at the Morgan Arboretum

Overview Although they are hidden amongst the leaf litter and often hard to spot, salamanders are key subjects in many ecological studies. While clearing out rocks from a site at the Morgan Arboretum, one of our team members noticed an abundance of salamanders underneath rocks located deeper in the soil. According to studies completed about […]

Amphibian Diversity, Abundance and Temporary Breeding Habitats in the Morgan Arboretum

We are the @ColdBloodedHopsters, a group of McGill students in the class St Lawrence Ecosystems (ENVB222) studying amphibians at the Morgan Arboretum. Make sure to follow us on Twitter for more updates on our research! Introduction: Although they only occupy 0.5% of all animal species, amphibians are a large and diverse group with over 6000 […]

Variation in the abundance of the red-backed “soil-amander”-Amphibians of the Morgan Arboretum

Introduction Nature is full of environmental and biological interactions. Some well-known, like how temperature and precipitation determine vegetation in different environments. Others are less obvious, and require keen observation to see. Last month, in the Morgan Arboretum, we looked at one of these subtle changes: how changing soil types affect the presence and abundance of […]

Salamanders of the Morgan Arboretum

Welcome fellow salamander enthusiasts! Some of you may already be familiar with our Twitter page (@MacSalamanders), if not, we are a group of four undergraduate students from McGill University (Montreal, QC) conducting a research project on salamanders. Salamanders and newts are amphibians within the Caudata order and belong to the Salamandridae family and Pleurodelinae subfamily, […]

Salamanders: their natural history and our research

Salamanders: their natural history and our research

Salamanders belong to the Caudata order. Along with Anura (frogs) and Gymnophiona (caecilians), they belong to the Amphibian group (Bishop 1943). Salamanders are often confused with lizards because of their similar body form but they lack scales. Instead salamanders have moist glandular skin that is permeable to water and unlike frogs, they have tails and […]
