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.

Efficient Masked Autoencoder for Birdsong Representation with Applications on Wild Bird Species Classification

open access: yesIntegrative Zoology, EarlyView.
Research on mosquito feeding preferences and the malaria parasites they transmit is essential for understanding the interactions between hosts, vectors, and parasites. In this study, vertebrate hosts were identified in 72 mosquitoes. Most blood meals (58.7%) came from birds, representing 25 species, while 40.0% came from mammals (13 species), and 1.3 ...

Linking Snake Behavior to Nest Predation in a Midwestern Bird Community

open access: yes, 2010
Nest predators can adversely affect the viability of songbird populations, and their impact is exacerbated in fragmented habitats. Despite substantial research on this predator-prey interaction, however, almost all of the focus has been on the birds ...

Domination Versus Sisterhoods in the Blood Microbiota of Migrating Birds: Patterns of Within‐ and Between‐Individual Blood Parasite Diversity Revealed Through Metabarcoding

open access: yesIntegrative Zoology, EarlyView.
Avian haemosporidian blood parasites are typically identified through Sanger sequencing of a partial cytochrome b fragment, the MalAvi barcoding region. Next‐generation sequencing is seldom used for avian blood parasite identification; this study demonstrates a higher detection rate of co‐infections via metabarcoding and its possible implications ...

Russet Sparrows spot alien chicks from their nests

open access: yesAvian Research, 2018
Background In coevolutionary interactions between brood parasites and their hosts, host parents are under strong selection to evolve defenses against parasitism.

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.

Adapting to Urban Heights: Multidimensional Gradients Drive Nest‐Selection Plasticity and Trade‐Offs in a Human‐Commensal Sparrow

open access: yesIntegrative Zoology, EarlyView.
Urban Eurasian tree sparrows exhibit pronounced nest‐site plasticity, exploiting vertical building space while preferring lower nest heights when sites are abundant. Nest decisions are driven by altitude and building height rather than other factors, indicating a shift toward anthropogenic resources in cities.
