The range of the barred owl (Strix varia) has expanded westward over the past century and now entirely overlaps the range of the federally threatened northern spotted owl (S. occidentalis caurina) in the Pacific Northwest. We compared Haemoproteus blood parasite assemblages among northern spotted owls in their native range and barred owls in both their native and invasive ranges to evaluate predictions of five hypotheses about parasites and biological invasions: (1) Enemy Release, where hosts… 
Spillover but no spillback of two invasive parasitic copepods from invasive Pacific oysters (Crassostrea gigas) to native bivalve hosts
TLDR
The high frequency of M. orientalis spillover, in particular to native mussels, suggests that Pacific oysters may cause strong parasite-mediated indirect impacts on native bivalve populations.
The Journal of Wildlife Management
Barred owls (Strix varia) are forest‐dwelling owls, native to eastern North America, with populations that expanded westward into the range of the spotted owl (Strix occidentalis). Barred owls exert
Potential trophic cascades triggered by the barred owl range expansion
TLDR
It is posited that shared prey species and those uniquely consumed by barred owls, along with other competing native predators, may experience changes in behavior, abundance, and distribution as a result of increased rates of predation by rapidly expanding populations of barred Owls.
Host dispersal and landscape conversion are associated with the composition of haemosporidian parasites of the golden-winged warbler
TLDR
Golden-winged warblers may have been sensitive to novel parasites as they dispersed, and the high prevalence and diversity of parasite lineages in the north-west extent of their breeding range (Manitoba) indicates that this population may face unique pressures.
Review of the effects of barred owls on spotted owls
Barred owls (Strix varia) are forest‐dwelling owls, native to eastern North America, with populations that expanded westward into the range of the spotted owl (Strix occidentalis). Barred owls exert

The northern spotted owl (Strix occidentalis caurina) was listed as threatened under the Endangered Species Act in 1990 (USFWS 1990). Providing adequate amounts of suitable forest cover to sustain

THE EPIZOOTIOLOGY AND ECOLOGICAL SIGNIFICANCE OF MALARIA IN HAWAIIAN LAND BIRDS
TLDR
Avian malaria probably did not reach epizootic proportions on Hawaii until after 1920, but since that time it has had a negative impact on the population dynamics of the native forest birds and is today a major limiting factor, restricting both abundance and distribution of these species on the island.
Prevalence and diversity patterns of avian blood parasites in degraded African rainforest habitats
TLDR
It is found that the prevalence of Leucocytozoon and Haemoproteus infections were significantly higher in undisturbed than in deforested habitats, demonstrating that anthropogenic habitat change can affect host–parasite systems and result in opposing trends in prevalence of haemosporidian parasites in wild bird populations.
Is invasion success explained by the enemy release hypothesis
TLDR
Given the complexity of processes that underlie biological invasions, it is argued against a simple relationship between enemy ‘release’ and the vigour, abundance or impact of NIS.
Diversity, Prevalence, and Host Specificity of Avian Plasmodium and Haemoproteus in a Western Amazon Assemblage
TLDR
Within a local Neotropical assemblage of avian haemosporidia, community organization is highly complex and part of this complexity can be attributed to differences in host life history; diversity, particularly of Plasmodium spp.
Community relationships of avian malaria parasites in southern missouri
TLDR
Host-parasite relationships in a local area, including the role of parasites in sexual selection and the evolutionary maintenance of sex, are likely to be complex, with population and evolutionary dynamics involving many actors.
Release from Parasites as Natural Enemies: Increased Performance of a Globally Introduced Marine Crab
TLDR
A global assessment of the effect of parasitism and predation on the ecological performance of European green crab populations found that introduced species suffer less from parasites compared to populations where they are native.
Range Expansion of Barred Owls, Part I: Chronology and Distribution
TLDR
More than 12,500 records of Barred Owls in their expanded range from the earliest records to the present are mapped, the species' distribution is drawn and the general timing and flow of the range expansion is inferred.
Hematozoa from the Spotted Owl
TLDR
There were significant differences in the prevalence of these species of parasites occurring among the five populations of northern and California spotted owls sampled in California.
Blood parasites and reproductive success of Tengmalm's owls: detrimental effects on females but not on males?
TLDR
Leucocytozoon ziemanni reduced clutch size of females in 1991 when the abundance of the main food was intermediate, but had no apparent detrimental effect in 1992 when food abundance peaked.
Parasite spillback: a neglected concept in invasion ecology?
TLDR
It is hypothesized that parasite spillback could occur when a nonindigenous species is a competent host for a native parasite, with the presence of the additional host increasing disease impacts in native species, and called for greater recognition of parasite spill back as a potential threat to native species.
