4090 Trachemys scripta elegans Competition Experimental Laboratory T. s. elegans outcompetes and negatively impacts the growth of Pseudemys rubriventris, a near-threatened turtle species native to the Mid-Atlantic region, through facilitated competition for limited food resources. 27501
4093 Trachemys scripta elegans Competition Experimental Field Trachemys scripta elegans outcompeted native European pond turtle Emys orbicularis for preferred basking sites in deep-water away from the pond’s banks. France 35747
4101 Trachemys scripta elegans Competition Experimental Field The health and survival of the endangered European pond turtle (Emys orbicularis) declined in the presence of T. s. elegans in experimental ponds. Ain, France 35766
4102 Trachemys scripta elegans Competition Experimental Laboratory T. s. elegans demonstrated stronger, more aggressive feeding behaviors and better resource acquisition when placed in a heterospecific environment with Mauremys leprosa. Also, in competition with T. s. elegans, M. leprosa reduced its basking activity and avoided basking near the invasive turtles. This response in M. leprosa can lead to decreased efficiency in thermoregulation in individuals and could have physiological implications for species outcompeted for basking sites by the invasive. Madrid Province, Spain 35767
4103 Trachemys scripta elegans Competition Experimental Laboratory In competition with T. s. elegans, Mauremys leprosa reduced its basking activity and avoided basking near the invasive turtles. Madrid Province, Spain 35768
4106 Trachemys scripta elegans Competition Observational N/A Red-eared Sliders have been shown to outcompete Chinese native turtle Mauremys sinensis for food, basking sites, and nesting sites. Scientists have also observed this species aggressively attacking other native turtles through biting, pushing, swiping, and climbing, sometimes disturbing the mating of sympatric turtles. China 35785
4381 Trachemys scripta elegans Competition Anecdotal N/A Researchers suggest that T. s. elegans poses a significant threat to the critically endangered species, Batagur baska, a river terrapin native to Singapore. 36308
4384 Trachemys scripta elegans Competition Experimental Field T. s. elegans overlaps in niche for food resources with Mauremys reevesii, an endangered Korean turtle species that is likely being displaced as a result. Korea 36316
4385 Trachemys scripta elegans Competition Experimental Field The Western pond turtle, Actinemys marmorata, exhibited increased health and body condition when T. s. elegans was removed from its habitat. 36317
4386 Trachemys scripta elegans Competition Experimental Laboratory Polo-Cavia et al. (2011) suggest that Mauremys leprosa, a native turtle of the Iberian Peninsula and an endangered species, is being displaced from its food niche as a result of T. s. elegans introductions and aggressive behaviors. 35767
4388 Trachemys scripta elegans Competition Experimental Laboratory In heterospecific groups, Red-eared Sliders outcompeted endangered European turtles (Emys orbicularis) for preferred basking habitat. 35747
4389 Trachemys scripta elegans Competition Anecdotal N/A Red-eared sliders outcompete other turtles in their invaded range for food, nesting sites, mates, or basking places. 35785
4390 Trachemys scripta elegans Competition Observational Field The invasive red-eared slider has been shown to reach maturity earlier, produce more eggs, have superior fertility, and higher competitive ability for food and habitat resources compared to several chelonians in its invaded range and most other turtles. This species was more fecund in Spain than in its native range. Spain 36318
4391 Trachemys scripta elegans Competition Observational Field Peterman and Ryan (2009) show that the painted turtle (Chrysemys picta) and the red-eared slider share basking habitat preferences, however, no significant impacts from this interaction have been observed. Central Canal, Indianapolis, IL 36319
5625 Trachemys scripta elegans Competition Anecdotal N/A Reportedly,Trachemys scripta elegans in Turtle Pond located in Central Park, New York have outcompeted both Chrysemys picta and Chelydra sp. 34112
5626 Trachemys scripta elegans Competition Observational Field Chrysemys picta picta has declined in some areas of New York state in part due to the presence of Trachemys scripta elegans. 34112
6130 Trachemys scripta elegans Competition Observational Field Competition and disease from introduced Red-eared Slider (Trachemys scripta elegans) is a threat to co-existing native turtles, specifically the Western Painted Turtle (Chrysemys picta bellii). Vancouver, Vancouver Island, Sunshine Coast, British Columbia 41421
6572 Trachemys scripta elegans Competition Experimental Laboratory Iberian anuran tadpoles altered their movements when chemical cues were from native chelonians, but did not respond to cues from invasive Trachemys scripta elegans. This response, probably due to a lack of coevolutionary history, may explain why invasive red-eared sliders have a competitive advantage over native Iberian terrapins for food resources. 35767
6573 Trachemys scripta elegans Competition Anecdotal N/A Researchers suggest that Trachemys scripta elegans poses a significant threat to the critically endangered species, Batagur baska, a river terrapin native to Singapore 40919
6574 Trachemys scripta elegans Competition Anecdotal N/A In sympatry, the invasive red-eared slider (Trachemys scripta elegans) has been shown to reach maturity earlier, produce more eggs, have superior fertility, and higher competitive ability for food and habitat resources compared to several chelonians in its invaded range and most other turtles. 35747
