The Piney Woods is a temperate coniferous forest terrestrial ecoregion in the Southern United States covering 54,400 square miles (141,000 km2) of East Texas, southern Arkansas, western Louisiana, and southeastern Oklahoma. These coniferous forests are dominated by several species of pine as well as hardwoods including hickory and oak. Historically the most dense part of this forest region was the Big Thicket though the lumber industry dramatically reduced the forest concentration in this area and throughout the Piney Woods during the 19th and 20th centuries. The World Wide Fund for Nature considers the Piney Woods to be one of the critically endangered ecoregions of the United States. The United States Environmental Protection Agency (EPA) defines most of this ecoregion as the South Central Plains.
The Credit River is a river in southern Ontario, which flows from headwaters above the Niagara Escarpment near Orangeville and Caledon East to empty into Lake Ontario at Port Credit, Mississauga.

Mont-Saint-Bruno National Park is a small national park of Quebec located near the municipality of Saint-Bruno-de-Montarville, 15 kilometres (9.3 mi) to the east of Montréal on the south shore of the Saint Lawrence River. The park, with an area of 8.84 square kilometres (3.41 sq mi), notably includes Mont Saint-Bruno, one of the Monteregian Hills which peaks at 218 metres (715 ft). The mountain is shared with the Ski Mont Saint-Bruno ski resort, a quarry and a small Canadian Forces training camp. Despite its relatively small size, the mountain is known for its rich fauna and flora. Situated at the heart of the old signory of Montarville, its many lakes have permitted the construction and exploitation of many water mills, contributing to the region's economical success. A building from one of those mills, the "Vieux Moulin", still stands to this day and is used as a rest area for skiers and hikers in different seasons.
There are 14 species of amphibians and 5 species of reptiles known to occur in Mount Rainier National Park.
Parthenogenesis is a form of reproduction where eggs develop without fertilization, resulting in unisexual species. This phenomenon is closely related with reproductive modes such as hybridogenesis, where fertilization occurs, but the paternal DNA is not passed on. Among amphibians, it is seen in numerous frog and salamander species, but has not been recorded in caecilians.
