“…In this way, we show the explicit link between population demography and size structure dynamics in the eastern red‐backed salamander. Along with other plethodontids, this species has a high sensitivity to temperature warming (Moore et al., 2018; Riddell et al., 2018), and has been hypothesized to undergo phenotypic changes under climate change. These changes include some natural populations decreasing in size (Caruso et al, 2014), while others increasing in size (McCarthy et al., 2017).…”

“…It is also a species that is highly sensitive to warm temperatures and habitat loss [29–32]. For example, their surface activity is known to be influenced by variations in temperature and rainfall [18] and climate-modelled distributions predict a contraction of its geographical range and other plethodontids under future warmer climates [33,34]. Under these conditions, we expected low densities for P. cinereus near its southern range limit.…”

Unexpected spatial population ecology of a widespread terrestrial salamander near its southern range edge

Under the current amphibian biodiversity crisis, common species provide an opportunity to measure population dynamics across a wide range of environmental conditions while examining the processes that determine abundance and structure geographical ranges. Studying species at their range limits also provides a window for understanding the dynamics expected in future environments under increasing climate change and human modification. We quantified patterns of seasonal activity, density and space use in the eastern red-backed salamander ( Plethodon cinereus ) near its southern range edge and compare the spatial ecology of this population to previous findings from the core of their range. This southern population shows the expected phenology of surface activity based on temperature limitations in warmer climates, yet maintains unexpectedly high densities and large home ranges during the active season. Our study suggests that ecological factors known to strongly affect amphibian populations (e.g. warm temperature and forest fragmentation) do not necessarily constrain this southern population. Our study highlights the utility of studying a common amphibian as a model system for investigating population processes in environments under strong selective pressure.

“…Yet, ecological conditions across the island seem favourable for these salamanders. Moore et al (2018) examined the current climatic niche of Eastern Red-backed Salamander across its native range and modelled how the species' distribution could shift in response to climate change. They noted that although the species was not yet present on Newfoundland, the current available climatic niche was suitable (Moore et al 2018).…”

Furthermore, being a generalist invertebrate predator (Maglia 1996) allows Eastern Red-backed Salamander to consume a wide array of potential prey items.…”

The island of Newfoundland has no native amphibian taxa, although six species of Anura (i.e., frogs and toads) have been introduced since European colonisation, four of which have established self-sustaining populations. Here, we document Eastern Red-backed Salamander (Plethodon cinereus) on Newfoundland for the first time, in what appears to be a self-sustaining population near Conception Bay South. This is the first species of Caudata (i.e., newts and salamanders) to have been introduced to the island, as well as the first occurrence of Eastern Red-backed Salamander establishing a population outside its native range. The impact that this non-native species might have on forest ecosystems on Newfoundland is unclear and further study is required to determine whether eradication of the species from Newfoundland is necessary or feasible.
