Infection reduces anti‐predator behaviors in house finches [PDF]

open access: yesJournal of Avian Biology, 2017
Infectious diseases can cause host mortality through direct or indirect mechanisms, including altered behavior. Diminished anti‐predator behavior is among the most‐studied causes of indirect mortality during infection, particularly for systems in which a parasite's life‐cycle requires transmission from prey to predator ...

Seasonal Patterns of Fat Deposits in Relation to Migratory Strategy in Facultative Migrants

open access: yesFrontiers in Ecology and Evolution, 2021
Physiological preparations for migration generally reflect migratory strategy. Migrant birds fuel long-distance flight primarily with lipids, but carrying excess fuel is costly; thus, the amount of fat deposited prior to departure often reflects the ...

More than putting on a performance in commercial homes: merging family practices and critical hospitality studies [PDF]

open access: yes, 2015
Critical hospitality studies and family studies have shown a developing theoretical convergence predicated by the ‘social turn’ in the study of hospitality.

Contrasting epidemic histories reveal pathogen-mediated balancing selection on class II MHC diversity in a wild songbird. [PDF]

open access: yesPLoS ONE, 2012
The extent to which pathogens maintain the extraordinary polymorphism at vertebrate Major Histocompatibility Complex (MHC) genes via balancing selection has intrigued evolutionary biologists for over half a century, but direct tests remain challenging ...

Are urbanization, biotic and social factors associated with the song frequency and song entropy attributes of three urban syntopic passerines?

open access: yesAvian Research
Urban environments have challenging characteristics for bird acoustic communication. High levels of anthropogenic noise, as well as vegetation structure (e.g., in urban parks), can potentially affect the song frequency characteristics of several bird ...

Complex interactions between bacteria and haemosporidia in coinfected hosts: An experiment

open access: yesEcology and Evolution, 2020
Hosts are typically coinfected by multiple parasite species whose interactions might be synergetic or antagonistic, producing unpredictable physiological and pathological impacts on the host. This study shows the interaction between Plasmodium spp.

Diverse wild bird host range of Mycoplasma gallisepticum in eastern North America. [PDF]

open access: yesPLoS ONE, 2014
Emerging infectious diseases often result from pathogens jumping to novel hosts. Identifying possibilities and constraints on host transfer is therefore an important facet of research in disease ecology.

Full Open Population Capture-Recapture Models with Individual Covariates [PDF]

open access: yes, 2010
Traditional analyses of capture-recapture data are based on likelihood functions that explicitly integrate out all missing data. We use a complete data likelihood (CDL) to show how a wide range of capture-recapture models can be easily fitted using ...

Rethinking brachycephaly: Anatomical implications and health considerations in lagomorphs

open access: yesThe Anatomical Record, EarlyView.
Abstract Brachycephaly in domestic rabbits is increasingly perceived by welfare organizations as associated with significant health complications, particularly oral pathologies. Despite this perception, comparative anatomical research into rabbit brachycephaly is limited compared to that of dogs and cats, compelling an in‐depth examination of its ...
