Rana sylvatica - an overview ScienceDirect Topic

  1. Rana sylvatica. Wood frogs are the only anuran for which a POS positive response has been demonstrated in response to freezing exposure (Moreira et al., 2016), supported by the evidence of increased enzyme activities of GPx and selenium-dependent GPx, as well as elevated GSH levels in several organs including brain, heart, kidney and liver during freezing (Joanisse and Storey, 1996)
  2. There are no recognized subspecies of the Wood Frog (Rana sylvatica). Frost et al. (2006) recommended placing these frogs in the genus Lithobates, but other authors argue against this, instead suggesting the recognition of subgenera within the monophyletic Rana (e.g., Pauley et al. 2009; Yuan et al. 201
  3. Rana sylvatica Wood Frog: family: Ranidae Taxonomic Notes: This species was placed in the genus Lithobates by Frost et al. (2006).However, Yuan et al. (2016, Systematic Biology, doi: 10.1093/sysbio/syw055) showed that this action created problems of paraphyly in other genera
  4. E' il caso di una rana che vive in Canada, la rana Sylvatica, che è in grado di resistere a temperature incredibili per un rettile, che notoriamente non ha la capacità di regolare il proprio.

  6. Il suo nome scientifico è Lithobates sylvaticus, ma è anche conosciuta come rana sylvatica o rana del legno. Vive soprattutto in Canada e Alaska, dove con l'arrivo dell'inverno le temperature calano drasticamente rendendo praticamente impossibile la vita normale a gran parte delle creature che abitano a quelle latitudini
  7. Praticamente a nessuno verrebbe in mente un anfibio, un animale a sangue freddo, eppure la rana lignea (Rana sylvatica) ha probabilmente l'adattamento al gelo più straordinario dell'intero regno.

Lithobates sylvaticus (antes Rana sylvatica) [2] é unha especie de ra amplamente distribuída en Norteamérica, desde o bosque boreal do Canadá e Alasca ao sur dos Montes Apalaches, con algunhas poboacións illadas notables noutras zonas, como en Carolina do Norte.A especie chamou a atención dos biólogos debido á súa tolerancia á conxelación, ao seu grao relativamente grande de vida.

Wood frogs (Rana sylvatica) can be distinguished from other local frogs by their dark mask extending back from each of their eyes.The rest of their body can vary from light tan to reddish brown; in fact, a single individual can vary their coloring seasonally. While other species, like the green frog, are often found in close proximity to water year round, wood frogs are rarely seen in. REPRODUCTION INTHE WOOD FROG, RANA SYLVATICA(ANURA:RANIDAE),FROM ARKANSAS The reproductive biology of the wood frog,Rana sylvatica, has received considerable scrutiny throughout much ofits broad range inNorth America (see review in Davis and Folkerts, 1986).

Yet for many species, there remain substantial gaps in our knowledge of such movement patterns. From 1999-2002, we documented movement patterns to and from breeding pools of both adult and juvenile Rana sylvatica LeConte (Wood Frog) and Ambystoma maculatum Shaw (Spotted Salamander) by using.

A slow decrease in ambient temperature (1°C every 2 days) from 3° to −2.1 °C was used to search for a specific trigger temperature. None was found. Instead it was found that, despite subzero temperature, animals which remained in a supercooled unfrozen state had low blood glucose (1.66. Rana sylvatica (wood frog) at southern latitudes, for example, migrate to ephemeral ravines to remain within suitable soil moisture levels (Rittenhouse & Semlitsch, 2007), suggesting that specific microhabitat selection can decrease chances of mortality vi Considerable study has focused on the physiological adaptations for freeze tolerance in the wood frog, Rana sylvatica, a northern species that overwinters within the frost zone, but little attention has been paid to the associated costs to organismal performance.Here we report that freezing causes transient impairment of locomotor endurance and adverse changes in exercise physiology that.

The Arctic Wood frog, (Rana Sylvatica) has an anti-freeze type blood that allows it to freeze during the winter months, then live throughout the season as usual when it thaws out. They can survive temperatures of up to minus 16 degrees Celsius in the Arctic Circle.
