The East Texas toad, commonly seen in the Big Thicket, has been controversial among herpetologist and taxonomist, some arguing that it is a distinct species (Anaxyrus velatus) while others argue that it is a hybrid between Woodhouse's toad (Anaxyrus woodhousii) found to the west and Fowler's toad (Anaxyrus fowleri) found to the east.
Extent of temperate broadleaf and mixed forests An example of temperate broadleaf and mixed forest in La Mauricie National Park, Quebec.. Temperate broadleaf and mixed forest is a temperate climate terrestrial habitat type defined by the World Wide Fund for Nature, with broadleaf tree ecoregions, and with conifer and broadleaf tree mixed coniferous forest ecoregions.
Alaska is the most biodiverse state with 15 ecoregions across three biomes in the same realm. California comes in a close second with 13 ecoregions across four biomes in the same realm. By contrast, Rhode Island is the least biodiverse with just one ecoregion—the Northeastern coastal forests —encompassing the entire state.
A new classification and linear sequence based on molecular data can be found in an article by Christenhusz et al. [6] The conifers are an ancient group, with a fossil record extending back about 300 million years to the Paleozoic in the late Carboniferous period; even many of the modern genera are recognizable from fossils 60–120 million ...
