The Tungara Frog: A Study in Sexual Selection and Communication
- M. Ryan
- Biology
- 10 February 1986
In a Panamanian pond, male tungara frogs ("Physalaemus pustulosus") gather in choruses, giving their "advertisement" call to the females that move among them. If a female chooses to make physical… Expand
The evolution of mating preferences and the paradox of the lek
- M. Kirkpatrick, M. Ryan
- Biology
- Nature
- 1991
Why do females prefer elaborate male mating displays in species where they receive little more from males than their sperm? Here we review three hypotheses for the evolution of mating preferences:… Expand
The Role of Body Size, Phylogeny, and Ambient Noise in the Evolution of Bird Song
- M. Ryan, Eliot A. Brenowitz
- Biology
- The American Naturalist
- 1 July 1985
Morton found that the average emphasized frequency in the songs of tropical bird species in low-forest habitats was lower than that of species in grassland or edge habitats. He suggested that this… Expand
What do animal signals mean?
- D. Rendall, M. Owren, M. Ryan
- Psychology
- Animal Behaviour
- 1 August 2009
Animal communication studies often use analogies to human language and related constructs such as information encoding and transfer. This commonality is evident even when research goals are very… Expand
Benefit to male sailfin mollies of mating with heterospecific females.
- I. Schlupp, C. Marler, M. Ryan
- Biology, Medicine
- Science
- 21 January 1994
Female gynogens reproduce clonally but rely on sperm from heterospecific males to initiate embryogenesis. It has been assumed that males gain no benefit from such matings; thus, selection should… Expand
Craniofacial ontogeny in centrosaurine dinosaurs (Ornithischia: Ceratopsidae): taxonomic and behavioral implications
- Scott D. Sampson, M. Ryan, D. Tanke
- Biology
- 1 November 1997
Centrosaurine ceratopsians are characterized by well developed nasal horncores or bosses, relatively abbreviated supraorbital horncores or bosses, and adorned parietosquamosal frills. Recent study of… Expand
Bat Predation and the Evolution of Frog Vocalizations in the Neotropics
Bat predation has probably had an important influence on the evolution of frog vocalizations in the Neotropics. The rate at which fringe-lipped bats capture frogs is significantly higher when the… Expand
Sexual selection, receiver biases, and the evolution of sex differences.
- M. Ryan
- Biology, Medicine
- Science
- 25 September 1998
REVIEW Recent approaches to analyzing the evolution of female mating preferences emphasize how historical influences on female receiver systems can bias the evolution of male traits that females find… Expand
Patterns of advertisement call evolution in toads and chorus frogs
- R. Cocroft, M. Ryan
- Biology
- Animal Behaviour
- 1 February 1995
Patterns of evolution in the acoustic signals of two groups of anuran amphibians were examined. Call character matrices for clades ofBufo(Bufonidae) andPseudacris(Hylidae) were derived from analysis… Expand
