Nest Predation and Nest-Site Selection of a Western Population of the Hermit Thrush
Audubon's Hermit Thrushes (Catharus guttatus auduboni) in central Arizona have a low nesting success (7 to 20%) due almost exclusively to nest predation. We examine the sites chosen for nesting and… Expand

An experimental test of colonization ability in the potentially invasive Didemnum perlucidum (Tunicata, Ascidiacea)
Exotic species invasions are one of the greatest threats to marine systems and ascidians have many characteristics that favor transport, colonization and establishment into new regions. Didemnum… Expand
Ascidians at the Pacific and Atlantic entrances to the Panama Canal
The Panama Canal region is susceptible to non-native species introductions due to the heavy international shipping traffic through the area. Ascidian introductions are occurring worldwide but little… Expand
Avoid nest predation when predation rates are low, and other lessons: testing the tropical–temperate nest predation paradigm
Nest predation is the most important cause of nest failure in most birds and latitudinal differences in nest predation rates and life histories suggest that nest predation has been influential in… Expand
Sexually distinct songs in the duet of the sexually monomorphic Rufous Hornero
- J. Roper
- 1 July 2005
Abstract The Rufous Hornero (Furnarius rufus: Family Furnariidae), common in southern Brazil, is a territorial, sexually monomorphic bird in which pairs sing duets. This family of birds is known for… Expand
The Rufous Hornero (Furnarius rufus) nest as an incubation chamber.
Foraging and incubation are mutually exclusive activities for parent birds. A trade-off is generated when a combination of food availability and temperature regulation force birds to choose one and… Expand
BREEDING BIOLOGY OF PASSERINES IN THE SUBTROPICAL BRAZILIAN ATLANTIC FOREST
Information on breeding biology of birds is fundamental for the understanding of life history evolution and conservation. This information is only beginning to accumulate for Neotropical birds but… Expand
A test of the Skutch hypothesis: does activity at nests increase nest predation risk?
Small clutches in tropical species of passerine birds may be a response to nest predation. The Skutch hypothesis predicts that nest predation increases with activity at nests, and activity at nests… Expand
Use of artificial substrata by introduced and cryptogenic marine species in Paranaguá Bay, southern Brazil
Abstract Ports are important locations for the introduction of marine species, while marinas and pontoons often serve as secondary habitats for these species. In a marina near Paranaguá Port, a major… Expand
