Status, Distribution, and Ecology of an Endangered Semi-Aquatic Frog (Atelognathus patagonicus) of Northwestern Patagonia, Argentina
It is concluded that A. patagonicus is gone from that lake, probably related to the introduction of an invasive fish species there, and high densities of animals the next year, as well as high levels of sick animals once again.
Plastic patterns in larval development of Endangered endemic Atelognathus patagonicus: implications for conservation strategies
The results highlight the importance of preserving a variety of wetlands, including both temporary and permanent ponds, to allow this species to continue to breed and develop in the face of current and potential anthropogenic disturbance, in particular that caused by the activity of local native pastoralists.
Relationship between morphotypes of Atelognathus patagonicus (Anura, Neobatrachia) and environmental conditions: evidence and possible explanation
It is believed that the change and subsequent reversal of the somatic features in these frogs are an opportunistic alternative showing remarkable plasticity of the species, which can thus inhabit both permanent and temporary ponds.
Role of the CNS in the control of the water economy of the toadBufo arenarum Hensel
Permeability of the skin to water is related to the osmolarity of the external environment in the normal toad and hypothalamic-hypophyseal mechanisms seem only in part to account for this responsiveness.
Dramatic decline and range contraction of the Endangered Patagonian frog Atelognathus patagonicus (Anura, Leptodactylidae)
The most severe problem facing the remaining populations is in the many lagoons currently not protected by Laguna Blanca National Park, and conservation efforts need to focus on the prevention of fish introductions in the wetlands areas on private land.
Antidiuretic responses to osmotic, ionic or volume stimulation of the brain in the unanesthetized toad, Bufo arenarum Hensel.
The brain of the toad is able to detect ionic and osmotic stimuli, these stimuli apparently affect different receptors in the brain, the antidiuresis initiated by these mechanisms is dependent on diencephalic integrity.
Seasonal trophic activity of the aquatic morphotype of Atelognathus patagonicus (Anura, Neobatrachia) and prey availability in the littoral benthos of a permanent pond in Argentinean Patagonia
The diet of the aquatic morphotype of Atelognathus patagonicus was studied in frogs collected from the Laguna Verde pond and there is a correspondence between the frogs' main food item and its presence in the benthos.
New obstetric systemic inflammatory response syndrome criteria for early identification of high-risk of sepsis in obstetric patients
The cut-off values for SIRS variables did not differ between healthy and infected obstetric patients, however, a higher cut-offs may help predict the population with a higher risk of severe maternal outcomes.
Feeding habits and their implications for the conservation of the endangered semiaquatic frog Atelognathus patagonicus (Anura, Neobatrachia) in a northwestern Patagonian pond
Data on the feeding habits of Atelognathus patagonicus in Laguna del Burro, in Neuquen Province is presented and conclusions about the design of conservation programs for the species are given.
Habitat Associations for the Endangered Frog Atelognathus patagonicus Within the Aquatic Environment: Key Microhabitats for Conservation
—The Laguna Blanca Aquatic Frog, Atelognathus patagonicus (Batrachylidae), is an endangered species endemic to a system of endorheic (i.e., no outlet) ponds in northwest Argentine Patagonia and is
