The impact of urbanization on health depends on the health metric, life stage and level of urbanization: a global meta-analysis on avian species

Proceedings of the Royal Society B Biological Sciences, Journal Year: 2024, Volume and Issue: 291(2027)

Published: July 17, 2024

Stressors associated with urban habitats have been linked to poor wildlife health but whether a general negative relationship between urbanization and animal can be affirmed is unclear. We conducted meta-analysis of avian literature test biomarkers differed on average non-urban environments, there are systematic differences across species, biomarkers, life stages species traits. Our dataset included 644 effect sizes derived from 112 articles published 1989 2022, 51 bird species. First, we showed that was no clear impact when categorized the sampling locations as or non-urban. However, did find small this dichotomous variable replaced by quantitative representing degree at each location. Second, dependent type biomarker measured well individual stage, young individuals being more negatively affected. comprehensive analysis calls for future studies disentangle specific urban-related drivers might obscured in categorical versus comparisons.

Energy input, habitat heterogeneity and host specificity drive avian haemosporidian diversity at continental scales

Proceedings of the Royal Society B Biological Sciences, Journal Year: 2024, Volume and Issue: 291(2018)

Published: March 6, 2024

The correct identification of variables affecting parasite diversity and assemblage composition at different spatial scales is crucial for understanding how pathogen distribution responds to anthropogenic disturbance climate change. Here, we used a database avian haemosporidian parasites test the taxonomic phylogenetic structure genera Plasmodium , Haemoproteus Leucocytozoon from three zoogeographic regions are related surrogate Earth's energy input, habitat heterogeneity (climatic diversity, landscape heterogeneity, host richness human disturbance) ecological interactions (resource use), which was measured by novel assemblage-level metric niche overlap (degree generalism). We found that components input explained variation in each genus. influences while degree generalism genera. Furthermore, attributes (human footprint) can filter assemblages their relatedness. Finally, assembly processes resource use within modify species assemblages. Overall, our study highlighted genus-specific patterns with budget, disturbances generalism.

Urbanization enhances body condition, but not innate immune defences, in a common waterbird

Royal Society Open Science, Journal Year: 2025, Volume and Issue: 12(1)

Published: Jan. 1, 2025

There is a growing body of evidence that urbanization can affect condition and immune function in wild birds, although these effects may be complex taxa-specific. Here, we assessed the on (size-corrected mass haemoglobin concentration) innate defences (haemolysis-haemagglutination assay, haptoglobin concentration bacterial killing assay) 136 Eurasian coots (Fulica atra) from three urban non-urban populations across Poland. We also quantified heterophil to lymphocyte ratio control for potential effect physiological stress defences. found showed significantly better than ones. At same time, no relationship between any defence or condition. Thus, our study offers support condition-dependent function. Our analyses revealed significant differences male female both defences; however, sex-specific responses urbanization. In conclusion, provides correlative habitat enhances condition, but not coot.

PATHOGEN-INDUCED STRESS IN WILD HOUSE FINCHES (HAEMORHOUS MEXICANUS): LEUKOCYTE DYNAMICS AS HEALTH INDICATORS

Journal of Wildlife Diseases, Journal Year: 2025, Volume and Issue: 61(2)

Published: May 16, 2025

Birds are frequently stressed by their exposure to parasites and pathogens. The heterophil lymphocyte (H:L) ratio has been proposed as a measure of physiological stress. This study investigates the prevalence bacterial pathogen Mycoplasma gallisepticum Haemosporidia in Mexican House Finches (Haemorhous mexicanus). To test extent which pathogens stress hosts we compared total differential leucocyte counts four groups birds with different infection statuses: co-infected M. haemosporidia, infected either or neither. We hypothesized that would exhibit higher stress, reflected leukocyte parameters, plus, based on previous experiments, both haemosporidia benefit from presence each other. found 73.6% were gallisepticum, 43.1% haemosporida. Both had load birds. Higher H:L ratios single infection. highlights complexity immune responses under co-infection. Our results contribute understanding host-pathogen interactions physiology wild birds, highlighting importance hematological parameters indicators providing insights into ecological impacts infections avian populations. emphasizes significance studying profiles wild.

Published: June 23, 2021

Humans and wildlife are at risk from certain vector-borne diseases such as malaria, dengue, West Nile yellow fevers. Factors linked to global change, including habitat alteration, land-use intensification, the spread of alien species, climate operating on a scale affect both incidence distribution many diseases. Hence, understanding drivers that regulate transmission pathogens in wild is great importance for ecological, evolutionary, health, economic reasons. In this literature review, we discuss ecological factors potentially affecting two mosquito-borne circulating naturally between birds mosquitoes, namely, virus (WNV) avian malaria parasites genus Plasmodium. Traditionally, study pathogen has focused only vectors or hosts interactions them, while role landscape largely been ignored. However, an point view, it essential not interaction each these organisms but also understand environmental scenarios which processes take place. We describe here some similarities differences how research into systems may facilitate greater dynamics wild.

Abstract Background As habitat fragmentation increases, ecological processes, including patterns of vector-borne pathogen prevalence, will likely be disrupted, but ongoing investigations are necessary to examine this relationship. Here, we report the differences in prevalence Lyme disease ( Borrelia burgdorferi sensu lato, s.l.) and haemoproteosis Haemoproteus spp.) pathogens avian populations a fragmented habitat. B. s.l. is generalist that transmitted by Ixodes pacificus vectors California, an parasite Culicoides vectors. Methods To determine whether biotic (avian mammalian abundance) or abiotic characteristics (patch size water availability) correlated with infection change, screened 176 birds sampled across seven sites oak woodland northern California. Results While factors increase both pathogens, spp. was only associated individual-level traits, specifically foraging substrate diet, community-level characteristics, total mammal and, specifically, rodent abundance. Proximity factor found significant for reinforces importance availability transmission cycles. Larger patch sizes did not significantly affect Haemoproteus, burgdorferi. Conclusions These results highlight while environmental (specifically fragmentation) have limited role indirect impact (community composition) can consequences birds. Given pervasiveness fragmentation, our broad significance. Graphical abstract

Disease transmission prediction across wildlife is crucial for risk assessment of emerging infectious diseases. Susceptibility host species to pathogens influenced by the geographic, environmental, and phylogenetic context specific system under study. We used machine learning analyze how such variables influence pathogen incidence multihost assemblages, including one direct (coronaviruses bats) two vector-borne systems (West Nile Virus [WNV] birds, malaria birds). Here we show that this methodology able provide reliable global spatial susceptibility predictions studied host–pathogen systems, even when using a small amount information (i.e., <20% in database). found avian was mostly affected environmental factors an interaction between phylogeny geography, WNV geographic distances, whereas coronavirus geography. This approach will help surveillance field efforts providing cost-effective decisions on where invest limited resources.
