Adult amphibians, for example, share a similar characteristic that makes them responsive to changes in … Indicator species are a type of organism that signal the health, or lack of health, of environmental conditions. Examples of indicator species include the wood stork, peppered moth, river otters and lichens. The gray treefrog, sometimes called the Northern gray treefrog, is closely related to the Cope’s gray treefrog (Hyla chrysoscelis), with overlapping range and identical physical appearance.These two species are distinguishable based on variation in their calls. Frog Fire Salvage Project MIS Report 2016 2 1. Tracking changes in the geographic range, the beginning and ending of the calling season, and the population of frogs and toads in Canada can help us understand changes occurring in the environment. Frogs as indicator species There are many questions on whether frogs are a good example of indicator species. Frogs, which are considered to be an indicator species, play an important role in the ecosystem because they act as hunters and prey. Explain that the presence or absence of an indicator species reveals the environmental condition, such as water quality. Massive frog die-offs in the past have often been linked to the negative aspects of urban development, like the contamination of local water resources. Back to the sea, certain fishes are also considered as indicator species because of how their population reacts to the condition of their habitats. Indicator species can be all types of animals, plants, lichens, algae or bacteria. Introduce the term indicator species. Photo source:, available as public domain. It also means that anything in the environment is really easy for them to absorb. invertebrates. In addition, lowland leopard frogs are an indicator species of ecosystem health, and measures to protect them will inevitably benefit other the many other animals that rely on desert water sources for drinking. If an environment is contaminated with things like pollutants their health will really be affected. New Caledonia has no native species, and Polynesia was never colonized by frogs, except perhaps for invasive cane toads. Amphibians, such as frogs and salamanders, are excellent indicator species for aquatic habitats. Other known predators include opossums, skunks and turtles. Introduction The purpose of this report is to evaluate and disclose the impacts of the Frog Fire Salvage Project (Frog Project) on the habitat of the thirteen (13) Management Indicator Species (MIS) identified in the Blue Mountains Frog Bio-indicators In order to determine which frog species would be useful as indicators of stormwater pollution in the Blue Mountains, 22 paired sites were selected across the mountains. The Blue Mountains Frog Bio-indicator Study (White 1999) is still the only study of this type to be carried out in Australia. Only two species made it to Fiji, whilst Vanuatu has no native species, except the green and golden bell frog, Litoria aurea, which was introduced from eastern Australia. Frogs are indicator species: Frogs have skin that is permeable, which means things can pass through it. Amphibians, particularly tree frogs, have long been used as symbols of environmental conservation because of their importance as indicator species. Lowland leopard frogs are an important component of Saguaro National Park’s unique aquatic biodiversity. Frogs and toads can be used as indicator species, because they are vulnerable to changes in the atmosphere, the land, or the water. At this scale, the effects of restoration on population size, health, behavior, and reproduction of individual indicator species could be used to judge restoration success. Indicator species have certain qualities that make them important for scientists to study. This allows them to both breath and drink through their skin. It may be that many amphibians can be a great indicator species due to their versatility when it comes to their relation with the ecosystem for obvious reasons. Gray Treefrog Fact Sheet Two gray treefrogs. Research at the local scale consists of perfecting methods to study and monitor amphibians in the field and using these methods to ask appropriate questions. Frog eggs and tadpoles are frequently eaten by leeches and large marine insects.
