“…Moreover, we also found that the variance explained by our model was higher when considering the random variable year, which could be due to the potential influence of yearly weather variablility and related food supply on the H/L ratio values (Norte et al 2009a;Banbura et al 2013;Fairhurst et al 2013). Finally, we cannot exclude the role of the high nest predation rates reported in this species (over 80% of nests in some Spanish populations, Herranz et al 1994;Pérez-Granados et al 2017;Gómez-Catasús et al 2021) and other berian groundnesting shrubsteppe passerines (> 70%, Suarez et al 1993, Yanes andSuárez 1995) in explaining the observed H/L ratio seasonal differences.…”

Stress in birds has been widely studied through the measurement of heterophil-to-lymphocyte ratio (H/L ratio). In this study we aimed to assess for the first time the potential variation of stress, measured as H/L ratio, associated to geography (between-country variation) and seasonality (between seasons and within the breeding season), as well as the leukocyte profiles, in the threatened Dupont’s Lark (Chersophilus duponti), using samples from Spain and Morocco. Furthermore, we tested whether variation in H/L ratio was associated with variables such as population density, presence of blood parasites and individual body condition. We found that H/L ratio did not vary between countries, but individuals captured during the breeding season showed higher values of H/L compared to non-breeding ones. Neither male density, nor date within the breeding season had an effect on the H/L ratio. In Spain, individuals with higher body condition showed lower H/L ratio regardless of whether they were malaria-infected. In Morocco, malaria-infected individuals showed higher values of H/L ratio than the non-infected birds. Moreover, we found that our average values of H/L ratio in Morocco were within the ranges of other passerines, but not in Spain. Individuals with higher H/L ratios may be more stressed or present higher capability to face stressful situations. Although H/L ratio is a useful and relatively easy way to obtain measure of stress, the impact that the environment might have on stress and the way it is explained by H/L ratio must be addressed carefully. This study provides new insight for this species’ biology and provides useful reference information to test the status and survival of other populations.

“…Clutch size usually varies between three and six eggs, with an incubation period of 11-14 days. fledglings leave the nest at between eight days (Dupont's lark) and 14 days (Tawny Pipit) (Calero-riestra & García, 2019;Cramp & Simmons, 1980;Gómez-Catasús et al, 2016;herranz et al, 2004;Pérez-Granados et al, 2016;Suárez, 1977).…”

“…The only exception is Dupont's lark, the resident species, whose first detected nesting attempt was in mid-March, coinciding with the start of the nest surveys. however, it is known that its reproductive period can extend from mid-late february to early July (Gómez-Catasús et al, 2016), though early dates may correspond with warmer locations in South or North-East Spain. In general, the dates provided in this work with those described so far for the Eurasian Skylark and the Western Black-eared Wheatear (Collar, 2021;.…”

SummaryThe co-occurrence of morphologically similar species may be enabled by differences in resource use that limit the effects of interspecific competition, allowing coexistence. This study aimed to evaluate differences in nest structure and to characterise nesting microhabitats to test for nesting niche segregation among sympatric steppe passerines. From 2016 to 2019, we monitored and characterised the nest structure and nesting habitat of 71 nests from five sympatric passerines in shrub steppes in Central Spain: the Eurasian Skylark Alauda arvensis, the Greater Short-toed Lark Calandrella brachydactyla, Dupont's Lark Chersophilus duponti, the Tawny Pipit Anthus campestris and the Western Black-eared Wheatear Oenanthe hispanica. Nest structure was characterised by eight morphometric variables, while principal component analyses (PCA), MANOVA and univariate ANOVA were performed to characterise and evaluate differences in nesting microhabitat between species in both horizontal and vertical dimensions. All species built their nests under short vegetation (< 20cm) and with a similar nest depth. However, there were significant differences among species for some of the considered variables. For example, the three monitored lark species built their nests in areas with lower plant cover compared to the two non-lark species. GLM on PCA axes showed that some species differed in some aspect of nesting niche. In general, the Eurasian Skylark built its nests in areas with higher grassland cover, while the Greater Short-toed Lark selected more open areas, with a higher bare ground cover. Dupont's Lark, the Tawny Pipit and the Western Black-eared Wheatear nested mainly in shrubby areas dominated by chamaephytes. Overall, our results suggest the existence of nesting microhabitat segregation, mainly of the Eurasian Skylark with the rest of the species, which may contribute to explaining the coexistence between species that could potentially compete for nesting sites. This work contributes to understanding how differences in species nest site preferences may facilitate coexistence between similar sympatric species.—Barrero, A., Cortés Caballero, B., Reverter, M., Gómez-Catasús, J., Bustillo-de la Rosa, D., Zurdo, J., Pérez-Granados, C. & Traba, J.

Gaussian processes and random fields have a long history, covering multiple approaches to representing spatial and spatio-temporal dependence structures, such as covariance functions, spectral representations, reproducing kernel Hilbert spaces, and graph based models. This article describes how the stochastic partial differential equation approach to generalising Matérn covariance models via Hilbert space projections connects with several of these approaches, with each connection being useful in different situations. In addition to an overview of the main ideas, some important extensions, theory, applications, and other recent developments are discussed. The methods include both Markovian and non-Markovian models, non-Gaussian random fields, non-stationary fields and space-time fields on arbitrary manifolds, and practical computational considerations.
