Mechanical injury is a prevalent challenge in the lives of animals with myriad potential
consequences for organisms, including reduced fitness and death. Research on animal …

Predator-induced defenses are well studied in plants and invertebrate animals, but have
only recently been recognized in vertebrates. Gray treefrog (Hylachrysoscelis) tadpoles …

In a replicated field experiment we studied the effects of natural densities of two exotic
consumers, the predatory and herbivorous signal crayfish (Pacifastacus leniusculus) and the …

Organisms that produce alternative, nondiscrete phenotypes in response to environmental
conditions are expected to alter their phenotypes in relation to the degree of environmental …

Two experimental approaches were used to determine if burst swimming speed in
Pseudacris regilla tadpoles is subject to selection by predatory garter snakes, Thamnophis …

Amphibian anomalies have been a source of curiosity for centuries and the literature on this
topic is enormous. We provide a comprehensive overview of the anomalies that have been …

Tadpoles are unusual among vertebrates in having a globose body with a laterally
compressed tail abruptly appended to it. Compared with most teleost fishes, tadpoles swim …

Many spatially complex environments are fractal, and consumers in these environments face
scale-dependent trade-offs between encountering high densities of small resource patches …

Synopsis. Tadpoles are exceptional among vertebrates in lacking vertebrae along most of
their body axis. Their caudal myotomes are also unusually simple for free-living vertebrates …

Interest in the culture of freshwater crayfish throughout Europe has increased during the last
few decades. However, the effects of both introduced and native crayfish species on the …
