Response to simultaneous dehydration and thermal stress in three species of Puerto Rican frogs
(Springer: Journal of Comparative Physiology B: Biochemical, Systemic, and Environmental Physiology, 1984-11)
The response to simultaneous temperature and dehydration stress was examined in three species of Puerto Rican frogs. Eleutherodactylus antillensis is found primarily in hot, arid grasslands at low altitudes. Eleutherodactylus ...
Male parental care and its adaptive significance in a neotropical frog
(Elsevier: Animal Behaviour, 1984-05)
In the Puerto Rican frog Eleutherodactylus coqui, parental care is performed exclusively by males, and consists of attending the eggs and hatchlings at a terrestrial oviposition site. The two major behavioural components ...
Water balance of terrestrial anuran (Eleutherodactylus Coqui) eggs: importance of parental care
(The Ecological Society of America: Ecology, 1984-02)
The terrestrial eggs of the coqui of Puerto Rico are brooded almost continuously by the male parent from the time of oviposition until the fully metamorphosed hatchlings emerge from the eggs 15-20 d later. The gelatinous ...
Specializations of the body form and food habits of snakes
(Oxford University Press: American Zoologist, 1983)
Viperid snakes have stouter bodies, larger heads, and longer jaws than snakes in other families; there are no major differences between the two subfamilies of vipers in these features. A suite of morphological characters ...
Population density of tropical forest frogs: relation to retreat sites
(American Association for the Advancement of Science: Science, 1983)
The forest frog Eleutherodactylus coqui defends specific sites for retreats and nests in the Luquillo Forest, Puerto Rico. The hypothesis that shortages of nest and retreat sites limit population size was tested by placing ...
Ecological correlates of anuran exercise physiology
(Springer: Oecologia, 1982-01)
Studies of exercise physiology of anuran amphibians have led to the suggestion that there is a dichotomy between species that depend upon movement to escape from predators and species that utilize static defenses. This ...
Activity metabolism of the toad (Bufo americanus): Ecological consequences of ontogenetic change
(Springer: Journal of Comparative Physiology B: Biochemical, Systemic, and Environmental Physiology, 1981-06)
Following metamorphosis, juvenile toads form dense, heliothermic aggregations on the margins of the ponds from which they emerge. After a period of growth and development, during which body mass increases ten-fold, the ...
Internal fertilization in an oviparous frog
(American Association for the Advancement of Science: Science, 1981-04)
Eleutherodactylus coqui, an oviparous frog, undergoes internal fertilization. If this mode of fertilization occurs in other species of anurans, interpretations of anuran reproductive strategies based on the assumption of ...
Blood oxygen transport and delivery in reptiles
(Oxford University Press: American Zoologist, 1980)
Cenozoic reptiles are characterized by physiological morphological and ecological systems with low energy requirements compared to those of mammals. Ectothermy and low resting rates of metabolism are the primary physiological ...
The Advantages of ectothermy for tetrapods
(University of Chicago Press: American Naturalist, 1980-01)
The way of life of amphibians and reptiles, in contrast to that of birds and mammals, is based on low energy flow. Many of the morphological and physiological characteristics of ectothermal tetrapods that are normally ...
