“…On the other hand, simple landscapes, with olive grove predominance, were associated to higher richness of hymenopteran parasitoid families (Pascual, Rescia, et al, 2022) and higher abundance of the ground beetle Pterostichus globosus (Fabricius, 1792) (Lantero et al, 2019). The attack of P. oleae on olives was also positively related with the area of olive groves (Pascual, Ortega, & Villa, 2022), and in other study areas the abundance of P. oleae increased for higher percentages of surrounding olive groves (Alves et al, 2021).…”

“…In this study, landscape heterogeneity was driven by the dominance of olive groves, other crops and shrublands. In the same study area, landscape diversity affected negatively richness of hymenopteran parasitoids, and abundance of the olive fruit fly, B. oleae (Ortega et al, 2022; Pascual, Rescia, et al, 2022). In addition, in other growing areas, diversity of land uses surrounding olive groves decreased B. oleae and P. oleae abundances (Alves et al, 2021; Ortega & Pascual, 2014; Villa et al, 2020, Villa et al, 2022).…”

“…A complex landscape with a diversity of land uses supports syrphids community better than a more homogeneous landscape dominated by olive groves, because wild land uses provide resources for syrphids. In the same study area, CAO had also a negative effect on other insects, such as bees, although the responses of the different families varied slightly (Pascual, 2022), lacewings (Neuroptera: Chrysopidae) (Pascual, Rescia, Ayca Ondul, Paul, & Ortega, 2022), or the ground beetle Orthomus barbarus (Dejean, 1828) (Lantero et al, 2019). On the other hand, simple landscapes, with olive grove predominance, were associated to higher richness of hymenopteran parasitoid families (Pascual, Rescia, et al, 2022) and higher abundance of the ground beetle Pterostichus globosus (Fabricius, 1792) (Lantero et al, 2019).…”

Sustainability of agroecosystems depends on the ecosystem services, provided by beneficial organisms, such as the syrphids (Diptera: Syrphidae) acting as other‐insect predators and pollinators in different crops. In the case of olive groves, syrphids are predators of important pests and are endangered by the continuous intensification of agriculture, including landscape simplification. In this work, the effect of landscape structure on the abundance and species richness of syrphids in the olive agroecosystem of central Spain is assessed. Adult syrphids were sampled in 2015 and 2016 in the centre of circular areas of 15 olive grove landscapes (from 250 to 1500 m radius) representing a gradient of landscape complexity, in the province of Madrid, central Spain. The syrphid assemblage was made up of 57 species, although Eupeodes corollae, Eristalis tenax, Eristalis similis and Chrysotoxum intermedium made up 76% of the captures. Syrphid abundance and species richness were favoured in complex landscapes, with low olive grove area (CAO). Other landscape indices showed also this trend although their effect was not as strong and consistent as that of CAO. The area of scrublands (CAS) favoured syrphids in spring, but was unfavourable in autumn. The effect of Shannon's Evenness Index (SHEI) and mean shape index (MSI) was less consistent. The effect of CAO increased with increasing buffers radii, while the effect of CAS, SHEI and MSI was detected in general at smaller radii, indicating these indices affect different processes. Redundancy analysis (RDA) detected some differences between species regarding their abundance in spring versus autumn, and their relationship with landscape indices. This work provides new evidence that maintenance of complex landscapes is essential for maintaining functional biodiversity in the olive agroecosystem.

The study of yield-limiting factors of rye, a typical European cereal, is a crucial concern today as it significantly impacts global food safety. The objecive of the study was to determine the contribution of agroecological factors, namely bioclimatic variables, soil parameters, and landscape diversity, to the variation of rye yields in the central and northern regions of Ukraine, which is one of the world’s five largest producers of this crop. A symmetric log-logistic model was used to describe the dynamics of rye yields, and the parameters of this model can be used to analyze the spatial dynamics of yields, in particular, such characteristic points of the yield model as: the lower limit of the response (the lowest yield level); the upper limit (the highest yield level); the slope of the response curve in the vicinity of the inflection point, which shows the rate of yield change over time, ED50 – the time required to reach half of the maximum yield growth. In the preliminary principal component analysis, we identified 4 climate principal components and 6 soil principal components. Landscape diversity was assessed based on the Shannon index and distance to the protected areas. The results of the regression analysis revealed a statistically significant relationship between the parameters of rye yield and the identified environmental drivers. Among the rye yield parameters, the highest sensitivity to environmental factors was the upper yield limit (70%), and the lowest was the rate of yield increase (25%). Only the highest rate of yield growth demonstrated liner dependence on the Shannon index. Among the soil factors, the most influential for rye yields was the particle size distribution and especially the sand content. The rye yield parameters were primarily influenced by the variability of the temperature regime throughout extreme periods of the year and contrast in the temperature conditions. The yield parameters of rye were contingent upon the diversity of the landscape cover. The correlation between almost all yield characteristics and landscape-ecological diversity was not linear, leading to the identification of an optimal level of diversity in natural protected areas which results in the best rye yields.
