Cardiovascular Plasticity and Adaptation of High‐Altitude Birds and Mammals

open access: yesIntegrative Zoology, EarlyView.
This schematic depicts the cardiovascular adaptations of mammals and birds to high‐altitude hypoxia. It highlights key phenotypic changes in oxygen transport and cardiac responses, driven by molecular mechanisms including transcriptional regulation and genetic modifications.

Urbanization and Vector Species Shape Avian Malaria Prevalence in Mosquitoes

open access: yesIntegrative Zoology, EarlyView.
Avian malaria prevalence was assessed in two mosquito species across urban and peri‐urban habitats. No infections were detected in either species in urban areas, while a 2.53% prevalence was found in the native Culex pipiens from peri‐urban sites, highlighting the influence of urbanization on parasite transmission dynamics.

The role of a synanthropic bird in the nest niche expansion of a secondary cavity nester to man‐made structures

open access: yesEcology and Evolution, 2022
Species with similar ecological characters often compete with each other; however, a species may also facilitate the survival or reproduction of another ecologically similar species, although such interaction is rarely documented in birds.

Fall Field Report, August–November 2015 [PDF]

open access: yes, 2015
To start, a housekeeping item: in the species accounts that follow, whenever I use the term migrant I am referring to fall migration only. Many species, of course, have differing migration strategies and timing in spring and fall. Much of the data used

Urbanization, environmental stabilization and temporal persistence of bird species: A view from Latin America [PDF]

open access: yes, 2018
Background. A scarcely studied consequence of urbanization is the effect of temporal stabilization of the environment on bird communities. This alteration is thought to dampen environmental variations between day and night, seasons and years, promoting a

Prey Partitioning in a Diverse Carnivore Community: Implications for Reintroduced Fishers in Washington

open access: yesAnimal Conservation, EarlyView.
Using fecal DNA metabarcoding, we quantified dietary overlap among reintroduced fishers and sympatric coyotes, bobcats, and Pacific martens in Washington's North Cascades. Niche overlap was substantial for common prey but varied with body size, revealing fine‐scale resource partitioning that may limit fishers' access to energetically efficient prey ...

Future Tense [PDF]

open access: yes, 2020
Nature - Humans - Past - Future - Presence - Absence These familiar terms are the stepping stones of thought that went into my thesis work. While some may pair these words together as dichotomies, I concentrate on the balancing act that exists between

Narratives of Strength: Exploring Storytelling as a Tool for Resilience in Families

open access: yesChild &Family Social Work, EarlyView.
ABSTRACT Resilience, originally viewed as a psychological capacity to ‘bounce back’ from challenges, is now understood to be shaped by broader social inequalities, including gender, socio‐economic status, politics and ethnicity. This study explores how stories and narratives can help nurture resilience and improve well‐being among those residing in an ...
