Red-eared Slider × Yellow-bellied Slider
The red-eared slider × yellow-bellied slider (''Trachemys scripta elegans'' × ''Trachemys scripta scripta'') is an intergradation of a red-eared slider and yellow-bellied slider subspecies. On the side of its head where a normal yellow-bellied slider would have solid yellow, there will be red interposed. The bottom of the shell is a bright yellow with varying numbers of black dots. In the wild it eats minnows, plants, carrion, snails and insects that fall in the water. The average lifespan is usually over 30 years. The yellow facial markings of the yellowbelly are more distinct in this species but the red ear can still be seen This species often behaves similarly to the red eared slider References External links Variation and Species Status of Slider Turtles (Emydidae: Trachemys) in the Southwestern United States and Adjacent MexicoHybrid Red Eared Slider X Yellow Belly Sliderat YouTube YouTube is a global online video platform, online video sharing and social media ...

Project Noah
Project Noah is an online community dedicated to explore and document wildlife across the globe. "Noah" is an acronym for "networked organisms and habitats". This community formerly had an iPhone app in iTunes and an Android app in Google Play, but is now web only. Project Noah aims to become a common mobile platform for documenting the world's organisms. Beyond documentation, the iPhone app offers users an opportunity to participate in ongoing citizen science research projects by tagging contributions into specific field missions and can be used as a location-based field guide as well. All contributors are connected with an online community. The project's co-founder, Yasser Ansari, believes that "not only is there an educational need and an environmental need but a deep, deep human need for all of us to reconnect with our planet." Project Noah has won several awards. Currently, Project Noah has contributors from over 55 countries participating in a variety of missions ranging ...

Intergradation
In zoology, intergradation is the way in which two distinct subspecies are connected via areas where populations are found that have the characteristics of both. There are two types of intergradation: primary and secondary intergradation. Primary intergradation This occurs in cases where two subspecies are connected via one or more intermediate populations, each of which is in turn intermediate to its adjacent populations and exhibits more or less the same amount of variability as any other population within the species. Adjacent populations and subspecies are subject to cline intergradation, and in these situations it is usually taken for granted that the clines are causally related (by natural selection) to environmental gradients.Mayr E, Ashlock PD (1991). ''Principles of Systematic Zoology''. Second edition. McGraw-Hill. . Secondary intergradation When contact between a geographically isolated subspecies is reestablished with the main body of the species or with another is ...

Red-eared Slider
The red-eared slider or red-eared terrapin (''Trachemys scripta elegans'') is a subspecies of the pond slider (''Trachemys scripta''), a semiaquatic turtle belonging to the family Emydidae. It is the most popular pet turtle in the United States, is also popular as a pet across the rest of the world, and is the most invasive turtle. It is the most commonly traded turtle in the world. The red-eared slider is native from the Midwestern United States to northern Mexico, but has become established in other places because of pet releases, and has become invasive in many areas where it outcompetes native species. The red-eared slider is included in the list of the world's 100 most invasive species. Etymology The red-eared slider gets its name from the small, red stripe around its ears, or where its ears would be, and from its ability to slide quickly off rocks and logs into the water. This species was previously known as Troost's turtle in honor of an American herpetologist ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Yellow-bellied Slider
The yellow-bellied slider (''Trachemys scripta scripta'') is a land and water turtle belonging to the family Emydidae. This subspecies of pond slider is native to the southeastern United States, specifically from Florida to southeastern Virginia, and is the most common turtle species in its range. It is found in a wide variety of habitats, including slow-moving rivers, floodplain swamps, marshes, seasonal wetlands, and permanent ponds. Yellow-bellied sliders are popular as pets. Description Adult male yellow-bellied sliders typically reach in length; females range from . The carapace (upper shell) is typically brown and black, often with yellow stripes. The skin is olive green with prominent patches of yellow down the neck and legs. As the name implies, the plastron (bottom shell) is mostly yellow with black spots along the edges. Adults tend to grow darker as they age. Yellow-bellied sliders are often confused with eastern river cooters, who also have yellow stripes on the ne ...

Trachemys
''Trachemys'' is a genus of turtles belonging to the family Emydidae. Members of this genus are native to the Americas, ranging from the Midwestern United States south to northern Argentina, but one subspecies, the red-eared slider (''T. scripta elegans''), has been introduced worldwide. Species under this genus are commonly referred to as sliders.

Hybrid Animals
In biology, a hybrid is the offspring resulting from combining the qualities of two organisms of different breeds, varieties, species or genera through sexual reproduction. Hybrids are not always intermediates between their parents (such as in blending inheritance), but can show hybrid vigor, sometimes growing larger or taller than either parent. The concept of a hybrid is interpreted differently in animal and plant breeding, where there is interest in the individual parentage. In genetics, attention is focused on the numbers of chromosomes. In taxonomy, a key question is how closely related the parent species are. Species are reproductively isolated by strong barriers to hybridisation, which include genetic and morphological differences, differing times of fertility, mating behaviors and cues, and physiological rejection of sperm cells or the developing embryo. Some act before fertilization and others after it. Similar barriers exist in plants, with differences in flowering tim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
