Pond Slider
The pond slider (''Trachemys scripta'') is a species of common, medium-sized, semiaquatic turtle. Three subspecies are described, the most recognizable of which is the red-eared slider (''T. s. elegans''), which is popular in the pet trade and has been introduced to other parts of the world by people releasing it to the wild. Hatchling and juvenile pond sliders have a green upper shell (carapace), yellow bottom shell ( plastron), and green and yellow stripes and markings on their skin. These patterns and colors in the skin and shell fade with age until the carapace is a muted olive green to brown and the plastron is a dull yellow or darker. Some sliders become almost black with few visible markings. The carapace is oval with a bit of rounding and a central crest with knobs, but these features soften and fade with age, adults being smoother and flatter. For determining an adult slider's sex, males typically have much longer front claws than adult females, while females usually have ...

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] |
Sunning (behaviour)
Sunning or basking, sometimes also known as sunbathing, is a thermoregulatory or comfort behaviour used by animals, especially birds, reptiles, and insects, to help raise their body temperature, reduce the energy needed for temperature maintenance or to provide comfort. They may also have additional functions of ridding animals of ectoparasites, bacteria, or excess moisture. Birds Birds adopt special postures when sunning, these may include spreading out their feathers, flattening their body on soil, showing either their upper parts to the sun or facing the sun. Some authors separate the behaviours into sun-basking and sun-exposure - the former term used when the behaviour is strictly thermoregulatory in function while the latter term may be more appropriate if the behaviour serves functions other than raising body temperature. In some species, the sunbathing posture is adopted in very hot weather and the birds sometimes stay in close contact with hot soil. Birds may fluff up th ...

Reptiles Of Mexico
Reptiles, as most commonly defined are the animals in the class Reptilia ( ), a paraphyletic grouping comprising all sauropsids except birds. Living reptiles comprise turtles, crocodilians, squamates (lizards and snakes) and rhynchocephalians (tuatara). As of March 2022, the Reptile Database includes about 11,700 species. In the traditional Linnaean classification system, birds are considered a separate class to reptiles. However, crocodilians are more closely related to birds than they are to other living reptiles, and so modern cladistic classification systems include birds within Reptilia, redefining the term as a clade. Other cladistic definitions abandon the term reptile altogether in favor of the clade Sauropsida, which refers to all amniotes more closely related to modern reptiles than to mammals. The study of the traditional reptile orders, historically combined with that of modern amphibians, is called herpetology. The earliest known proto-reptiles originated around 31 ...

Turtles Of North America
Turtles are an order of reptiles known as Testudines, characterized by a special shell developed mainly from their ribs. Modern turtles are divided into two major groups, the Pleurodira (side necked turtles) and Cryptodira (hidden necked turtles), which differ in the way the head retracts. There are 360 living and recently extinct species of turtles, including land-dwelling tortoises and freshwater terrapins. They are found on most continents, some islands and, in the case of sea turtles, much of the ocean. Like other amniotes (reptiles, birds, and mammals) they breathe air and do not lay eggs underwater, although many species live in or around water. Turtle shells are made mostly of bone; the upper part is the domed carapace, while the underside is the flatter plastron or belly-plate. Its outer surface is covered in scales made of keratin, the material of hair, horns, and claws. The carapace bones develop from ribs that grow sideways and develop into broad flat plates tha ...

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.

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 ...

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 ...

Pond Sliders In Prospect Park (03861)
A pond is an area filled with water, either natural or artificial, that is smaller than a lake. Defining them to be less than in area, less than deep, and with less than 30% emergent vegetation helps in distinguishing their ecology from that of lakes and wetlands.Clegg, J. (1986). Observer's Book of Pond Life. Frederick Warne, London Ponds can be created by a wide variety of natural processes (e.g. on floodplains as cutoff river channels, by glacial processes, by peatland formation, in coastal dune systems, by beavers), or they can simply be isolated depressions (such as a kettle hole, vernal pool, prairie pothole, or simply natural undulations in undrained land) filled by runoff, groundwater, or precipitation, or all three of these. They can be further divided into four zones: vegetation zone, open water, bottom mud and surface film. The size and depth of ponds often varies greatly with the time of year; many ponds are produced by spring flooding from rivers. Ponds may be f ...

List Of Invasive Alien Species Of Union Concern
In 2016, following the EU Regulation 1143/2014 on Invasive Alien Species (IAS), the European Commission published a first list of 37 IAS of Union concern. The list was first updated in 2017 and comprised 49 species. Since the second update in 2019, 66 species are listed as IAS of EU concern. The species on the list are subject to restrictions on keeping, importing, selling, breeding and growing. Member States of the European Union must take measures to stop their spread, implement monitoring and preferably eradicate these species. Even if they are already widespread in the country they are expected to manage the species to avoid further spread. __TOC__ Sortable table of invasive alien species of Union concern ResourcesEU brochure on the 2017 list update with 49 species(pdf format)JRC report on the baseline distribution of the 37 species on the first list See also * List of invasive species in Europe (extensive list of alien species occurring in Europe) References {{Reflist ...

Carl Peter Thunberg
Carl Peter Thunberg, also known as Karl Peter von Thunberg, Carl Pehr Thunberg, or Carl Per Thunberg (11 November 1743 – 8 August 1828), was a Swedish naturalist and an "apostle" of Carl Linnaeus. After studying under Linnaeus at Uppsala University, he spent seven years travelling in southern Africa and Asia, collecting and describing many plants and animals new to European science, and observing local cultures. He has been called "the father of South African botany", "pioneer of Occidental Medicine in Japan", and the "Japanese Linnaeus". Early life Thunberg was born and grew up in Jönköping, Sweden. At the age of 18, he entered Uppsala University where he was taught by Carl Linnaeus, regarded as the "father of modern taxonomy". Thunberg graduated in 1767 after 6 years of studying. To deepen his knowledge in botany, medicine and natural history, he was encouraged by Linnaeus in 1770 to travel to Paris and Amsterdam. In Amsterdam and Leiden Thunberg met the Dutch botanist ...

Carapace
A carapace is a Dorsum (biology), dorsal (upper) section of the exoskeleton or shell in a number of animal groups, including arthropods, such as crustaceans and arachnids, as well as vertebrates, such as turtles and tortoises. In turtles and tortoises, the underside is called the plastron. Crustaceans In crustaceans, the carapace functions as a protective cover over the cephalothorax (i.e., the fused head and thorax, as distinct from the abdomen behind). Where it projects forward beyond the eyes, this projection is called a rostrum (anatomy), rostrum. The carapace is Calcification, calcified to varying degrees in different crustaceans. Zooplankton within the phylum Crustacea also have a carapace. These include Cladocera, ostracods, and Isopoda, isopods, but isopods only have a developed "cephalic shield" carapace covering the head. Arachnids In arachnids, the carapace is formed by the fusion of prosomal tergites into a single Plate (animal anatomy), plate which carries the e ...
