“…Reasons explaining such environmental specialisation could be related to the invertebrate host specialisation and/or by haemosporidian life-history characteristics [ 23 ]. Remarkably, our findings revealed some differences in relation to previous studies evaluating single species or singular avian communities [ 1 , 24 – 26 , 57 ]. Thus, the presence of Plasmodium had been mostly explained with few predictors, namely the temperature of the warmest month [ 1 , 25 – 26 ] and rainfall of the warmest months [ 24 ].…”

Mountains are well-suited systems to disentangle the factors driving distribution of parasites due to their heterogeneity of climatic and habitat conditions. However, the information about the relative importance of environmental factors governing the distribution of avian haemosporidians on temperate mountains is very limited. The main goal of the present study is to identify the factors determining prevalence and richness in avian haemosporidians (Plasmodium, Haemoproteus and Leucocytozoon) at the community level along elevational gradients on two mountain ranges located around the northern and southern limits of the Iberian Peninsula (Spain). We used samples from 68 avian species and 1,460 breeding individuals caught over widespread woodland and open habitats. Our findings confirmed the importance of climatic variables explaining prevalence and richness on Iberian mountains. However, landscape variables and other factors named host richness and migration behaviour explained more variation than climatic ones. Plasmodium genus preferred open and warm habitats. Water sources were also important for the southern but not for the northern mountain. Haemoproteus and Leucocytozoon showed affinities for woodland areas. Climatic conditions for Haemoproteus and Leucocytozoon were dependent on the mountain range suggesting some adaptation of avian haemosporidian and their invertebrate vectors to the climatic particularities of both mountain massifs. In contrast to Plasmodium and Haemoproteus genera, Leucocytozoon prevalence and richness values were significantly higher in the southern mountain range. Overall, our findings at the community level has enriched the relative weight and effect direction of environmental factors governing the distribution and prevalence of the avian haemosporidian community. Also, our results provide a caution message about the precision of predictive models on parasite distributions based on climatic variables, since such predictions could overestimate the effect of climate change scenarios on the transmission of the haemosporidians.

“…However, in some cases, relationships between hematozoa infection and measures of body mass, body condition, and survival varied among hematozoa genera infecting birds and demographic characteristics of host populations including species, age, and sex (Schrader et al 2003;Ishak et al 2010;Lachish et al 2011;Rojo et al 2013;Meixell et al 2016). Other studies have found no relationship between hematozoa infection and bird growth (Shutler et al 1999b), wing length (Shurulinkov et al 2012), body mass (Bennett et al 1988;Shurulinkov et al 2012;Shutler et al 1999b), condition (Ashford 1971;Shurulinkov et al 2012;Sorensen et al 2016), or other health metrics (Shutler et al 1996(Shutler et al , 1999bStjerman et al 2004).…”

Waterfowl managers lack information regarding factors that may be reducing the positive response of waterfowl body condition to habitat improvements. Protozoan blood parasites (i.e., hematozoa) are commonly found in birds and have been related to reduced body mass, wing length, and body condition. We studied relationships between 12 measures of hematozoa infection and body mass, wing length, and body mass divided by wing length (i. After accounting for variation due to species, age-sex cohort, Central Valley region, and month, wing length, body mass, and body condition index were found to be negatively related to infection by Leucocytozoon and by ''any hematozoa'' but not related to infection by only Plasmodium or Haemoproteus, or coinfections of greater than one genus or parasite haplotype (albeit few ducks had Plasmodium or Haemoproteus infection or coinfections). Evidence of a negative relationship with infection was stronger for body mass and body condition index than for wing length and indicated that the relationships varied among species, age-sex cohorts, regions, and months. Compared with uninfected ducks, hematozoa-infected duck body mass, wing length, and body condition index was À1.63% (85% CI ¼À2.79% to À0.47%), À0.12% (À0.41% to 0.17%), and À1.38% (À2.49% to À0.26%), respectively. Although seemingly small, the À1.63% difference in body mass represents a large percentage (e.g., 38% for northern pintail) of the observed increase in wintering duck body mass associated with Central Valley habitat improvements. Because infection prevalence and relationship to body condition might change over time because of climate or other factors, tracking hematozoa infection prevalence might be important to inform and accurately assess the effect of conservation programs designed to improve waterfowl body condition.
