New insights in gill/buccal rhythm spiking activity and CO2 sensitivity in pre- and post-metamorphic tadpoles (Pelophylax ridibundus)

, 2013
Central CO2chemosensitivity is crucial for all air-breathing vertebrates and raises the question of itsrole in ventilatory rhythmogenesis. In this study, neurograms of ventilatory motor outputs recorded infacial nerve of premetamorphic and ...

Morphology, ultrastructure and molecular characterisation of Spiroxys japonica Morishita, 1926 (Spirurida: Gnathostomatidae) from Pelophylax nigromaculatus (Hallowell) (Amphibia: Ranidae) [PDF]

, 2014
Gnathostomatid nematodes identified morphologically as Spiroxys japonica Morishita, 1926 were collected from the dark-spotted frog Pelophylax nigromaculatus (Hallowell) (Amphibia: Ranidae) in China.

Assessing the Presence, Pattern, and Environmental Correlates of Seasonal Skin Thickening in Anurans

Integrative Zoology, EarlyView.
Histological sections, like that of the ventral pectoral skin of Lithobates pipiens, were measured to assess variation in skin thickness throughout the year in three North American anuran species. After correcting for individual body size, we test whether skin thickness changes throughout the year and which factors (environment or life history) explain

The behavioral response of larval amphibians (Ranidae) to threats from predators and parasites. [PDF]

PLoS ONE, 2012
Organisms are exposed to strong selective pressures from several sources, including predators and pathogens. Response to such interacting selective pressures may vary among species that differ in life history and ecology in predictable ways.

Implementing real‐time acoustic monitoring for conservation: A case study using edge computing and satellite transmission

Conservation Science and Practice, EarlyView.
We evaluated a prototype acoustic monitoring device that performs onboard species classification and transmits detection summaries via satellite, enabling near real‐time data access from remote field sites. Deployed alongside conventional autonomous recording units at eight Northern Spotted Owl territories, the system demonstrated successful ...

American bullfrog (Lithobates catesbeianus) invasion in California

, 2020
Invasive species have far-reaching ecological and economic impacts. The American bullfrog (Lithobates catesbeianus) has spread globally through anthropogenic activity and has been named one of the world's worst invasive species. Bullfrogs have especially impacted native amphibians in California through predation, competition, and disease. Bullfrogs are

Morphological characterization of the gonads of bullfrog tadpoles (Lithobates catesbeianus) [PDF]

Journal of Morphological Sciences, 2015
Abstract Introduction: This work describes various aspects of early gonadal development of female and male in pre-metamorphic tadpoles (Lithobates catesbeianus) at Gosner stage 25. Materials and Methods: Ovaries and testicles were prepared for routine light microscopy for morphological study and for acridine orange technique fluroescent ...

Worldwide Invasions of Centrarchidae: The Dark Side of the Sunfish Family

Fish and Fisheries, EarlyView.
ABSTRACT Freshwater fish invasions are major drivers of global ecological change, disrupting native biodiversity and ecosystem functions. However, many invasive fish hold significant socioeconomic value, resulting in conflict over their management. Centrarchidae, which are globally distributed and are important for sportfishing and aquaculture, are now

Oviduct topography and irrigation in the bullfrog Lithobates catesbeianus (Shaw, 1802)

Biotemas, 2014
The bullfrog (Lithobates catesbeianus) is a species native to North America. It can reach about 20 cm in length and a body weight of 500 g. We used 30 adult frogs of the species Lithobates catesbeianus laying eggs to observe the oviduct. The animals were
