Article
Leticia Soares, Auteur ; GRACIELA Escudero, Auteur ; Victor A. S. Penha, Auteur ; Robert E. Ricklefs, AuteurAlthough shorebirds (Charadriiformes: suborders Scolopaci and Charadrii) face physiological stress during migration and experience a wide range of vector-suitable habitats across their distributions, haemosporidian parasites (order Haemosporida)[...]
Article
Alix E. Matthews, Auteur ; Vincenzo A. Ellis, Auteur ; Alison A. Hanson, Auteur ; Jackson R. Roberts, Auteur ; Robert E. Ricklefs, Auteur ; Michael D. Collins, AuteurHaemosporidian parasites (genera Plasmodium and Haemoproteus) are common blood parasites of birds transmitted by dipteran insect vectors. We analyzed blood samples from 329 individuals of 43 bird species in eastern Tennessee to better understand[...]

Annual adult survival in several new world passerine birds based on age ratios in museum collections
Robert E. Ricklefs, Auteur ; Toshi Tsunekage, Auteur ; Russell E. Shea, AuteurWe estimated annual survival from proportions of first-year and older birds in museum collections of several species of North American and Neotropical passerine birds (Order Passeriformes). The quality of estimates of survival from museum specim[...]
Article
Karen L. Krijgsveld, Auteur ; Robert E. Ricklefs, Auteur ; G. Henk Visser, AuteurWe measured daily energy expenditure (DEE) during the development periods of precocial chicks of five species of Arctic shorebirds spanning a broad range in size, in order to investigate the relationships between DEE, body size, and growth rate.[...]
Article
Robert E. Ricklefs, Auteur ; Julia Dodge Gray, Auteur ; Steven C. Latta, Auteur ; Maria Svensson-Coelho, AuteurWe compared the haemosporidian parasite faunas (Plasmodium and Haemoproteus) of small land birds on the islands of St Lucia, St Vincent and Grenada in the southern Lesser Antilles. The islands differ in distance from the South American source of[...]

Article
W. Douglas Robinson, Auteur ; Suzanne H. Austin, Auteur ; Tara R. Robinson, Auteur ; Robert E. Ricklefs, AuteurGrowth of avian embryos depends on heat transferred from incubating parents. Parental behavior, including nest characteristics, can influence the length of the incubation period by varying the temperature of incubated eggs, the length of parenta[...]
Article
Robert E. Ricklefs, Auteur ; Jeffrey Brawn, AuteurMany species of tropical birds have prolonged incubation periods compared to other tropical species and to most species in temperate latitudes. One hypothesis for prolonged incubation is that these tropical species reduce nest attendance to mini[...]
Article
Sylvia M. Fallon, Auteur ; Robert E. Ricklefs, AuteurMost comparative studies of avian blood parasites based on visual inspection of smears have reported Haemoproteus infections to be more prevalent than Plasmodium infections in both tropical and temperate locations. Recently, molecular techniques[...]

Article
Steven C. Latta, Auteur ; Robert E. Ricklefs, AuteurWe used PCR to screen for the presence of haemosporidian parasites (Phylum: Apicomplexa; Order: Haemosporida) in avian blood samples, and sequenced the parasite mitochondrial cytochrome b gene from infected hosts, to study patterns in the preval[...]
Article
Qinfeng Guo, Auteur ; Robert E. Ricklefs, AuteurThe species richness of 109 amphi-Pacific disjunct genera was examined in eastern Asia and North America. Although the entire flora of eastern Asia contains approximately one-third more species than that of North America, the difference in speci[...]
