    • The abundance of salamanders in forest stands with different histories of disturbance 

      Pough, F. Harvey; Smith, Ellen; Rhodes, Donald; Collazo, Andres (Elsevier: Forest Ecology and Management, 1987-07)
      Because of the importance of salamanders in forest food chains, the effects of forest management practices on populations of these animals warrant consideration. We compared the numbers and activity patterns of salamanders ...

    • Acid precipitation and embryonic mortality of spotted salamanders, Ambystoma maculatum 

      Pough, F. Harvey (American Association for the Advancement of Science: Science, 1976-04-02)
      Spotted salamanders breed in temporary pools formed in early spring by melted snow and rain. Many of these pools reflect the low pH of precipitation in the northeastern United States. Egg mortality is low (less than 1 ...

    • Acid precipitation and reproductive success of ambystoma salamanders 

      Pough, F. Harvey; Wilson, Richard (Springer: Water, Air and Soil Pollution, 1977-03)
      : The two species of mole salamander that occur in the Ithaca, New York, region (Ambystoma maculatum and A. jeffersonianum) breed in temporary ponds that are formed by accumulation of melted snow and spring rains. Water ...

    • Activity metabolism of the toad (Bufo americanus): Ecological consequences of ontogenetic change 

      Taigen, Theodore; Pough, F. Harvey (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 ...

    • The Advantages of ectothermy for tetrapods 

      Pough, F. Harvey (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 ...

    • Blood oxygen transport and delivery in reptiles 

      Pough, F. Harvey (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 ...

    • Diploid and tetraploid grey treefrogs (Hyla chrysoscelis and Hyla versicolor) have similar metabolic rates 

      Kamel, S.; Marsden, J.; Pough, F. Harvey (Elsevier: Comparative Biology and Physiology A, 1985)
      We measured oxygen consumption of the diploid frog Hyla chrysoscelis and its recently evolved tetraploid cryptic species Hyla versicolor at rest and during forced locomotory exercise. We also measured whole-body lactic ...

    • Ecological correlates of anuran exercise physiology 

      Taigen, Theodore; Emerson, Sharon; Pough, F. Harvey (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 ...

    • The ecological cost of morphological specialization: feeding by a fossorial lizard 

      Andrews, Robin; Pough, F. Harvey; Collazo, Andres; de Queiroz, A. (Springer: Oecologia, 1987-08)
      Head size and shape of reptiles may reflect selection for multiple uses. For example, sexual selection for large head size may enhance feeding efficiency. In contrast, morphological characteristics of the heads of fossorial ...

    • The effect of rattlesnake venom on digestion of prey 

      Thomas, Richard; Pough, F. Harvey (Elsevier: Toxicon, 1979)
      Rattlesnake venom injected into live mice before they were swallowed by non-venomous snakes speeded the process of digestion. This effect of venom was more pronounced when digestion was tested at 15°C than at 25°C. The ...

    • Effects of Body Temperature and Hydration State on Organismal Performance of Toads, Bufo americanus 

      Preest, Marion; Pough, F. Harvey (The University of Chicago Press: Physiological and Biochemical Zoology, 2003-03)
      Temperature and humidity are dominant environmental variables affecting performance of nocturnal, terrestrial amphibians. Toads are frequently active at body temperatures (Tb) and hydration states (HS) that yield suboptimal ...

    • Energy costs of subduing and swallowing prey for a lizard 

      Pough, F. Harvey; Andrews, Robin (The Ecological Society of America: Ecology, 1985-10)
      We measured the oxygen consumption (aerobic energy cost) and lactic acid production (anaerobic energy cost) of scincid lizards, Chalcides ocellatus, eating domestic crickets. Aerobic metabolism accounted for 90% or more ...

    • Internal fertilization in an oviparous frog 

      Townsend, Daniel; Stewart, Margaret; Pough, F. Harvey; Brussard, Peter (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 ...

    • Leech-Repellent Property of Eastern Red-Spotted Newts, Notophthalmus viridescens 

      Pough, F. Harvey (American Association for the Advancement of Science: Science, 1971-12-10)
      Eastern red-spotted newts (Notophthalmus viridescens, Salamandridae) are rarely attacked by leeches. This protection is not shared by related salamandrids or by Ambystoma (Ambystomatidae). Tetrodotoxin is not the repelent. ...

    • Male parental care and its adaptive significance in a neotropical frog 

      Townsend, Daniel; Stewart, Margaret; Pough, F. Harvey (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 ...

    • Melanin deposits associated with the venom glands of snakes 

      Pough, F. Harvey; Kwiecinski, Gary; Bemis, Willy (Wiley: Journal of Morphology, 1978-01)
      Melanin deposits in the heads of both true vipers (Viperinae) and pit vipers (Crotalinae) are concentrated over the dorsal and dorsolateral aspects of the venom glands. This pigment may occur in any or all of six sites ...

    • Metabolic correlates of anuran behavior 

      Taigen, Theodore; Pough, F. Harvey (Oxford University Press: American Zoologist, 1985)
      Frogs exhibit extensive diversity in their repertoires of social, reproductive, defensive, and predatory behavior, and in the metabolic processes that support these activities. Three aspects of anuran biology (foraging ...

    • Metabolic correlates of the foraging and social behaviour of dart-poison frogs 

      Pough, F. Harvey; Taigen, Theodore (Elsevier: Animal Behaviour, 1990-01)
      The foraging and social behaviour of four species of Panamanian dart-poison frogs, Dendrobatidae, were recorded and that information was combined with an analysis of aerobic and anaerobic metabolism and with published ...

    • Metabolism and activity of the spanish fringe-toed lizard (Lacertidae: acanthodactylus erythrurus) 

      Pough, F. Harvey; Busack, Stephan (Elsevier: Journal of Thermal Biology, 1978-10)
      1.In the field, adult fringe-toed lizards (Acanthodactylus erythrusus) had a mean body temperature of 38.8 ± 0.2 (S.E.) °C while subadults maintained a significantly lowr temperature (x average = 35.4 +/- 0.5 degrees ...

    • Mimicry of vertebrates: are the rules different? 

      Pough, F. Harvey (University of Chicago Press: American Naturalist, 1988-06)
      Examples of mimicry among vertebrates are numerically fewer than examples involving insects. The relatively small number of species of vertebrates, compared with the number of species of insects, probably explains some of ...
