Nestling growth rate and food consumption increases under experimentally prolonged daylength in a New World sparrow

Journal of Avian Biology, Volume 2023, Issue 11-12, November/December 2023., 2023
When evaluating avian reproduction, life history theory examines the trade‐offs between parental effort, the number and size of offspring, and the rate of nestling development. The growth rates and body sizes of developing birds vary geographically and can diverge with both latitude and migratory strategy.

Delayed maturity does not offset negative impact afflicted by ectoparasitism in salmon

Theoretical Ecology, 2021
The negative effects of parasitism on host population dynamics may be mediated by plastic compensatory life-history changes in hosts. Theory predicts that hosts should shift their life-history towards early reproduction in response to virulent pathogens ...

Ectoparasitism of the feather chewing louse Colpocephalum trichosum on the Andean Condor Vultur gryphus

Neotropical Biodiversity, 2021
S Feather chewing lice are common and important ectoparasites of birds. Here we report for the first time the presence of the ectoparasite, Colpocephalum trichosum Harrison1916 (Phthiraptera: Menoponidae on the Andean condor Vultur gryphus Linnaeus, 1758

Sexual and developmental variations of ecto-parasitism in damselflies.

PLoS ONE, 2022
The prevalence and intensity of parasitism can have different fitness costs between sexes, and across species and developmental stages. This variation could arise because of species specific sexual and developmental differences in body condition ...

Infestation of two shrimp species of the genus Palaemon Fabricius, 1798 (Decapoda, Palaemonidae) by an isopod of the genus Probopyrus Giard & Bonnier, 1888 (Bopyridae) from the Brazilian southeast coast

Nauplius, 2018
We determined the infestation rate of Probopyrus sp. in populations of Palaemon pandaliformis (Stimpson, 1871) and P. northropi (Rankin, 1898) in the Ubatumirim River, localized in a mangrove ecosystem on Ubatumirim Beach, northern coast of the state of ...

Patterns of infestation by the trombiculid mite Eutrombicula alfreddugesi in four sympatric lizard species (genus Tropidurus) in northeastern Brazil

Parasite, 2008
We studied the parasitism by the chigger mite Eutrombicula alfreddugesi on four sympatric lizard species of the genus Tropidurus in Morro do Chapéu, Bahia state, Brazil: T. hispidus, T. cocorobensis, T. semitaeniatus and T. erythrocephalus.

The marine leech Stibarobdella loricata (Harding, 1924) (Hirudinea, Piscicolidae), parasitic on the angel shark Squatina spp. and sandtiger shark Carcharias taurus Rafinesque, 1810 (Chondrichthyes: Squatinidae, Carchariidae) in Southern Brazilian waters

Brazilian Journal of Biology
The presence of the marine leech, Stibarobdella loricata (Harding, 1924) (Hirudinea, Piscicolidae), is reported on the southern coast of Brazil, based on seven lots with 47 specimens, between 71 and 182 mm in total length, collected on the dorsal region ...
