The Greenhouse Frog (Eleutherodactylus planirostris) in the United States

open access: yesEDIS
This publication summarizes general knowledge about the greenhouse frog, a species introduced and established in the United States. Our target audience is primarily homeowners in Hawaii and Florida where the greenhouse frog is most common, but residents

Outbreeding depression in the common frog, Rana temporaria

open access: yesConservation Genetics, 2005
Theory suggests that parental relatedness is a continuous variable with a fitness optimum that we heretoforth will refer to as ‘optimal outbreeding’. In the present paper, we test this proposition from a conservation (translocation) perspective. Amphibians are facing a global decline and many amphibian populations are today small and threatened by ...

Amphibians and Reptiles of United States Department of Defense Installations [PDF]

open access: yes, 2018
The U.S. Department of Defense (DoD) occupies approximately 10.1 million ha of land within the U.S. spanning most ecosystems contained therein. To date, no comprehensive agency-wide inventory of amphibian and reptile species has been compiled.

Stochastic orders and the frog model

open access: yes, 2017
The frog model starts with one active particle at the root of a graph and some number of dormant particles at all nonroot vertices. Active particles follow independent random paths, waking all inactive particles they encounter. We prove that certain frog

Abnormality in the Urostyle of the Common Frog [PDF]

open access: yesNature, 1887
ATTENTION has recently been drawn to abnormalities in the vertebral column of Rana. (See Bourne, Quarterly Journal of Microscopical Science, January 1884; Howes, Anatomischer Anzeiger, 1 Jahrgang, 1886, Nr. 11; Lloyd Morgan, NATURE, November 1886.) One form of such abnormality is the addition of a supernumerary (tenth) vertebra.

Road Impacts on Abundance, Call Traits, and Body Size of Rainforest Frogs in Northeast Australia

open access: yesEcology and Society, 2010
Frogs are potentially sensitive indicators of road impacts, with studies indicating particular susceptibility to road mortality. Calling, i.e., breeding, behavior could also be affected by traffic noise.

Amphibian chytridiomycosis : a review with focus on fungus-host interactions [PDF]

open access: yes, 2015
Amphibian declines and extinctions are emblematic for the current sixth mass extinction event. Infectious drivers of these declines include the recently emerged fungal pathogens Batrachochytrium dendrobatidis and Batrachochytrium salamandrivorans ...

The tiger salamander as a promising alternative model organism to the axolotl for fracture healing and regenerative biology research

open access: yesThe Anatomical Record, EarlyView.
Abstract Scientists have been captivated by the ability to regenerate, focusing on uncovering the mechanisms of epimorphic regeneration and applying them to human medicine. The axolotl (Ambystoma mexicanum) has become the most intensively studied model in tetrapod regeneration research, particularly concerning limb regeneration.

Differential Uptake of Gold Nanoparticles by 2 Species of Tadpole, the Wood Frog (Lithobates Sylvaticus) and the Bullfrog (Lithobates Catesbeianus)

open access: yes, 2017
Engineered nanoparticles are aquatic contaminants of emerging concern that exert ecotoxicological effects on a wide variety of organisms. We exposed cetyltrimethylammonium bromide–capped spherical gold nanoparticles to wood frog and bullfrog tadpoles ...
